Space policy of the United States

From Wikipedia, the free encyclopedia

The space policy of the United States includes both the making of space policy through the legislative process, and the implementation of that policy in the civilian and military US space programs through regulatory agencies. The early history of United States space policy is linked to the US–Soviet Space Race of the 1960s, which gave way to the Space Shuttle program. There is a current debate on the post-Space Shuttle future of the civilian space program.

Space policy process

United States space policy is drafted by the Executive branch at the direction of the President of the United States, and submitted for approval and establishment of funding to the legislative process of the United States Congress

Space advocacy organizations may provide advice to the government and lobby for space goals. These include advocacy groups such as the Space Science Institute, National Space Society, and the Space Generation Advisory Council, the last of which among other things runs the annual Yuri's Night event; learned societies such as the American Astronomical Society and the American Astronautical Society; and policy organizations such as the National Academies.

Drafting

In drafting space policy, the President consults with the National Aeronautics and Space Administration (NASA), responsible for civilian and scientific space programs, and with the Department of Defense, responsible for military space activities, which include communications, reconnaissance, intelligence, mapping, and missile defense. The President is legally responsible for deciding which space activities fall under the civilian and military areas. The President also consults with the National Security Council, the Office of Science and Technology Policy, and the Office of Management and Budget.

The 1958 National Aeronautics and Space Act, which created NASA, created a National Aeronautics and Space Council chaired by the President to help advise him, which included the Secretary of State, Secretary of Defense, NASA Administrator, Chairman of the Atomic Energy Commission, plus up to one member of the federal government, and up to three private individuals "eminent in science, engineering, technology, education, administration, or public affairs" appointed by the President. Before taking office as President, John F. Kennedy persuaded Congress to amend the Act to allow him to set the precedent of delegating chairmanship of this council to his Vice President (Lyndon B. Johnson). The Council was discontinued in 1973 during the presidency of Richard M. Nixon. In 1989, President George H. W. Bush re-established a differently constituted National Space Council by executive order, which was discontinued in 1993 by President Bill Clinton. President Donald Trump reestablished the Council by executive order in 2017.

International aspects of US space policy may involve diplomatic negotiation with other countries, such as the 1967 Outer Space Treaty. In these cases, the President negotiates and signs the treaty on behalf of the United States according to his constitutional authority, then presents it to the Congress for ratification.

Legislation

Once a request is submitted, the Congress exercises due diligence to approve the policy and authorize a budgetary expenditure for its implementation. In support of this, civilian policies are reviewed by the House Subcommittee on Space and Aeronautics and the Senate Subcommittee on Science and Space. These committees may exercise oversight of NASA's implementation of established space policies, monitoring progress of large space programs such as the Apollo program, and in special cases such as serious space accidents like the Apollo 1 fire, where Congress oversees NASA's investigation of the accident. 


The Senate Foreign Relations Committee conducts hearings on proposed space treaties, and the various appropriations committees have power over the budgets for space-related agencies. Space policy efforts are supported by Congressional agencies such as the Congressional Research Service and, until it was disbanded in 1995, the Office of Technology Assessment, as well as the Congressional Budget Office and Government Accountability Office.

Congress' final space policy product is, in the case of domestic policy a bill explicitly stating the policy objectives and the budget appropriation for their implementation to be submitted to the President for signature into law, or else a ratified treaty with other nations.

Implementation

Civilian space activities have traditionally been implemented exclusively by NASA, but the nation is transitioning into a model where more activities are implemented by private companies under NASA's advisement and launch site support. In addition, the Department of Commerce's National Oceanic and Atmospheric Administration operates various services with space components, such as the Landsat program.

Military space activities are implemented by the Air Force Space Command, Naval Space Command, and Army Space and Missile Defense Command.

Licensing

Any activities "which are intended to conduct in the United States a launch of a launch vehicle, operation of a launch or re-entry site, re-entry of a re-entry vehicle" needs a license to operate in outer space. This license needs to by applied for by "any citizen of or entity organized under the laws of the United States, as well as other entities, as defined by space-related regulations, which are intended to conduct in the United States… should obtain a license form the Secretary of Transportation" compliance is monitored by the FAA, FCC and the Secretary of Commerce.

Space programs in the budget

Funding for space programs occurs through the federal budget process, where it is mainly considered to be part of the nation's science policy. In the Obama administration's budget request for fiscal year 2011, NASA would receive $11.0 billion, out of a total research and development budget of $148.1 billion. Other space activities are funded out of the research and development budget of the Department of Defense, and from the budgets of the other regulatory agencies involved with space issues.

International law

The United States is a party to four of the five space law treaties ratified by the United Nations Committee on the Peaceful Uses of Outer Space. The United States has ratified the Outer Space Treaty, Rescue Agreement, Space Liability Convention, and the Registration Convention, but not the Moon Treaty.

The five treaties and agreements of international space law cover "non-appropriation of outer space by any one country, arms control, the freedom of exploration, liability for damage caused by space objects, the safety and rescue of spacecraft and astronauts, the prevention of harmful interference with space activities and the environment, the notification and registration of space activities, scientific investigation and the exploitation of natural resources in outer space and the settlement of disputes."

The United Nations General Assembly adopted five declarations and legal principles which encourage exercising the international laws, as well as unified communication between countries. The five declarations and principles are:
The Declaration of Legal Principles Governing the Activities of States in the Exploration and Uses of Outer Space (1963)
All space exploration will be done with good intentions and is equally open to all States that comply with international law. No one nation may claim ownership of outer space or any celestial body. Activities carried out in space must abide by the international law and the nations undergoing these said activities must accept responsibility for the governmental or non-governmental agency involved. Objects launched into space are subject to their nation of belonging, including people. Objects, parts, and components discovered outside the jurisdiction of a nation will be returned upon identification. If a nation launches an object into space, they are responsible for any damages that occur internationally.
The Principles Governing the Use by States of Artificial Earth Satellites for International Direct Television Broadcasting (1982)
The Principles Relating to Remote Sensing of the Earth from Outer Space (1986)
The Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992)
The Declaration on International Cooperation in the Exploration and Use of Outer Space for the Benefit and in the Interest of All States, Taking into Particular Account the Needs of Developing Countries (1996)

History

Eisenhower administration

President Dwight Eisenhower was skeptical about human spaceflight, but sought to advance the commercial and military applications of satellite technology. Prior to the Soviet Union's launch of Sputnik 1, Eisenhower had already authorized Project Vanguard, a scientific satellite program associated with the International Geophysical Year. As a supporter of small government, he sought to avoid a space race which would require an expensive bureaucracy to conduct, and was surprised by, and sought to downplay, the public response to the Soviet launch of Sputnik. In an effort to prevent similar technological surprises by the Soviets, Eisenhower authorized the creation in 1958 of the Defense Advanced Research Projects Agency (DARPA), responsible for the development of advanced military technologies.

Space programs such as the Explorer satellite were proposed by the Army Ballistic Missile Agency (ABMA), but Eisenhower, seeking to avoid giving the US space program the militaristic image Americans had of the Soviet program, had rejected Explorer in favor of the Vanguard, but after numerous embarrassing Vanguard failures, was forced to give the go-ahead to the Army's launch.

Later in 1958, Eisenhower asked Congress to create an agency for civilian control of non-military space activities. At the suggestion of Eisenhower's science advisor James R. Killian, the drafted bill called for creation of the new agency out of the National Advisory Committee for Aeronautics. The result was the National Aeronautics and Space Act passed in July 1958, which created the National Aeronautics and Space Administration (NASA). Eisenhower appointed T. Keith Glennan as NASA's first Administrator, with the last NACA Director Hugh Dryden serving as his Deputy.
 
NASA as created in the act passed by Congress was substantially stronger than the Eisenhower administration's original proposal. NASA took over the space technology research started by DARPA. NASA also took over the US manned satellite program, Man In Space Soonest, from the Air Force, as Project Mercury.

Kennedy administration

Early in John F. Kennedy's presidency, he was inclined to dismantle plans for the Apollo program, which he had opposed as a senator, but postponed any decision out of deference to his vice president whom he had appointed chairman of the National Advisory Space Council and who strongly supported NASA due to its Texas location. This changed with his January 1961 State of the Union address, when he suggested international cooperation in space. 

In response to the flight of Yuri Gagarin as the first man in space, Kennedy in 1961 committed the United States to landing a man on the Moon by the end of the decade. At the time, the administration believed that the Soviet Union would be able to land a man on the Moon by 1967, and Kennedy saw an American Moon landing as critical to the nation's global prestige and status. His pick for NASA administrator, James E. Webb, however pursued a broader program incorporating space applications such as weather and communications satellites. During this time the Department of Defense pursued military space applications such as the Dyna-Soar spaceplane program and the Manned Orbiting Laboratory. Kennedy also had elevated the status of the National Advisory Space Council by assigning the Vice President as its chair.

Johnson administration

President Lyndon Johnson was committed to space efforts, and as Senate majority leader and Vice President, he had contributed much to setting up the organizational infrastructure for the space program. However, the costs of the Vietnam War and the programs of the Great Society forced cuts to NASA's budget as early as 1965. However, the Apollo 8 mission carrying the first men into lunar orbit occurred just before the end of his term in 1968.

Nixon administration

President Nixon visits the Apollo 11 astronauts in quarantine after observing their landing in the ocean from the deck of the aircraft carrier USS Hornet.
 
Apollo 11, the first Moon landing, occurred early in Richard Nixon's presidency, but NASA's budget continued to decline and three of the planned Apollo Moon landings were cancelled. The Nixon administration approved the beginning of the Space Shuttle program, but did not support funding of other projects such as a Mars landing, colonization of the Moon, or a permanent space station.

On January 5, 1972, Nixon approved the development of NASA's Space Shuttle program, a decision that profoundly influenced American efforts to explore and develop space for several decades thereafter. Under the Nixon administration, however, NASA's budget declined. NASA Administrator Thomas O. Paine was drawing up ambitious plans for the establishment of a permanent base on the Moon by the end of the 1970s and the launch of a manned expedition to Mars as early as 1981. Nixon, however, rejected this proposal. On May 24, 1972, Nixon approved a five-year cooperative program between NASA and the Soviet space program, which would culminate in the Apollo-Soyuz Test Project, a joint-mission of an American Apollo and a Soviet Soyuz spacecraft, during Gerald Ford's presidency in 1975.

Ford administration

Space policy had little momentum during the presidency of Gerald Ford. NASA funding improved somewhat, the Apollo–Soyuz Test Project occurred and the Shuttle program continued, and the Office of Science and Technology Policy was formed.

Carter administration

The Jimmy Carter administration was also fairly inactive on space issues, stating that it was "neither feasible nor necessary" to commit to an Apollo-style space program, and his space policy included only limited, short-range goals. With regard to military space policy, the Carter space policy stated, without much specification in the unclassified version, that "The United States will pursue Activities in space in support of its right of self-defense."

Reagan administration

The first flight of the Space Shuttle occurred in April 1981, early in President Ronald Reagan's first term. Reagan in 1982 announced a renewed active space effort, which included initiatives such as privatization of the Landsat program, a new commercialization policy for NASA, the construction of Space Station Freedom, and the military Strategic Defense Initiative. Late in his term as president, Reagan sought to increase NASA's budget by 30 percent. However, many of these initiatives would not be completed as planned. 

The January 1986 Space Shuttle Challenger disaster led to the Rogers Commission Report on the causes of the disaster, and the National Commission on Space report and Ride Report on the future of the national space program.

George H. W. Bush administration

President George H. W. Bush continued to support space development, announcing the bold Space Exploration Initiative, and ordering a 20 percent increase in NASA's budget in a tight budget era. The Bush administration also commissioned another report on the future of NASA, the Advisory Committee on the Future of the United States Space Program, also known as the Augustine Report.

Clinton administration

During the Clinton administration, Space Shuttle flights continued, and the construction of the International Space Station began. 

The Clinton administration's National Space Policy (Presidential Decision Directive/NSC-49/NSTC-8) was released on September 14, 1996. Clinton's top goals were to "enhance knowledge of the Earth, the solar system and the universe through human and robotic exploration" and to "strengthen and maintain the national security of the United States." The Clinton space policy, like the space policies of Carter and Reagan, also stated that "The United States will conduct those space activities necessary for national security." These activities included "providing support for the United States' inherent right of self-defense and our defense commitments to allies and friends; deterring, warning, and if necessary, defending against enemy attack; assuring that hostile forces cannot prevent our own use of space; and countering, if necessary, space systems and services used for hostile purposes." The Clinton policy also said the United States would develop and operate "space control capabilities to ensure freedom of action in space" only when such steps would be "consistent with treaty obligations."

George W. Bush administration

The launch of the Ares I-X prototype on October 28, 2009 was the only flight performed under the Bush administration's Constellation program.
 
The Space Shuttle Columbia disaster occurred early in George W. Bush's term, leading to the report of the Columbia Accident Investigation Board being released in August 2003. The Vision for Space Exploration, announced on January 14, 2004 by President George W. Bush, was seen as a response to the Columbia disaster and the general state of human spaceflight at NASA, as well as a way to regain public enthusiasm for space exploration. The Vision for Space Exploration sought to implement a sustained and affordable human and robotic program to explore the solar system and beyond; extend human presence across the solar system, starting with a human return to the Moon by the year 2020, in preparation for human exploration of Mars and other destinations; develop the innovative technologies, knowledge, and infrastructures both to explore and to support decisions about the destinations for human exploration; and to promote international and commercial participation in exploration to further U.S. scientific, security, and economic interests.

To this end, the President's Commission on Implementation of United States Space Exploration Policy was formed by President Bush on January 27, 2004. Its final report was submitted on June 4, 2004. This led to the NASA Exploration Systems Architecture Study in mid-2005, which developed technical plans for carrying out the programs specified in the Vision for Space Exploration. This led to the beginning of execution of Constellation program, including the Orion crew module, the Altair lunar lander, and the Ares I and Ares V rockets. The Ares I-X mission, a test launch of a prototype Ares I rocket, was successfully completed in October 2009. 

A new National Space Policy was released on August 31, 2006 that established overarching national policy that governs the conduct of U.S. space activities. The document, the first full revision of overall space policy in 10 years, emphasized security issues, encouraged private enterprise in space, and characterized the role of U.S. space diplomacy largely in terms of persuading other nations to support U.S. policy. The United States National Security Council said in written comments that an update was needed to "reflect the fact that space has become an even more important component of U.S. Economic security, National security, and homeland security." The Bush policy accepted current international agreements, but stated that it "rejects any limitations on the fundamental right of the United States to operate in and acquire data from space," and that "The United States will oppose the development of new legal regimes or other restrictions that seek to prohibit or limit U.S. access to or use of space."

Obama administration

The Obama administration commissioned the Review of United States Human Space Flight Plans Committee in 2009 to review the human spaceflight plans of the United States and to ensure the nation is on "a vigorous and sustainable path to achieving its boldest aspirations in space," covering human spaceflight options after the time NASA plans to retire the Space Shuttle.

On April 15, 2010, President Obama spoke at the Kennedy Space Center announcing the administration's plans for NASA. None of the 3 plans outlined in the Committee's final report were completely selected. The President cancelled the Constellation program and rejected immediate plans to return to the Moon on the premise that the current plan had become nonviable. He instead promised $6 billion in additional funding and called for development of a new heavy lift rocket program to be ready for construction by 2015 with manned missions to Mars orbit by the mid-2030s. The Obama administration released its new formal space policy on June 28, 2010, in which it also reversed the Bush policy's rejection of international agreements to curb the militarization of space, saying that it would "consider proposals and concepts for arms control measures if they are equitable, effectively verifiable and enhance the national security of the United States and its allies."

The NASA Authorization Act of 2010, passed on October 11, 2010, enacted many of these space policy goals.

Trump administration

President Trump signs an executive order re-establishing the National Space Council, with astronauts Dave Wolf and Al Drew, and Apollo 11 astronaut Buzz Aldrin (left-to-right) looking on.
 
On June 30, 2017, President Donald Trump signed an executive order to re-establish the National Space Council, chaired by Vice President Mike Pence. The Trump administration's first budget request keeps Obama-era human spaceflight programs in place: commercial spacecraft to ferry astronauts to and from the International Space Station, the government-owned Space Launch System, and the Orion crew capsule for deep space missions, while reducing Earth science research and calling for the elimination of NASA's education office.

On December 11, 2017, President Trump signed Space Policy Directive 1, a change in national space policy that provides for a U.S.-led, integrated program with private sector partners for a human return to the Moon, followed by missions to Mars and beyond. The policy calls for the NASA administrator to "lead an innovative and sustainable program of exploration with commercial and international partners to enable human expansion across the solar system and to bring back to Earth new knowledge and opportunities." The effort will more effectively organize government, private industry, and international efforts toward returning humans on the Moon, and will lay the foundation that will eventually enable human exploration of Mars.

The President stated "The directive I am signing today will refocus America's space program on human exploration and discovery." "It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use. This time, we will not only plant our flag and leave our footprints -- we will establish a foundation for an eventual mission to Mars, and perhaps someday, to many worlds beyond." 

"Under President Trump's leadership, America will lead in space once again on all fronts," said Vice President Pence. "As the President has said, space is the 'next great American frontier' – and it is our duty – and our destiny – to settle that frontier with American leadership, courage, and values. The signing of this new directive is yet another promise kept by President Trump." 

Among other dignitaries on hand for the signing, were NASA astronauts Sen. Harrison "Jack" Schmitt, Buzz Aldrin, Peggy Whitson, and Christina Koch. Schmitt landed on the Moon 45 years to the minute that the policy directive was signed as part of NASA's Apollo 17 mission, and is the most recent living person to have set foot on our lunar neighbor. Aldrin was the second person to walk on the Moon during the Apollo 11 mission. Whitson spoke to the president from space in April aboard the International Space Station and while flying back home after breaking the record for most time in space by a U.S. astronaut in September. Koch is a member of NASA's astronaut class of 2013.

The Orion Multi-Purpose Crew Vehicle (Orion MPCV) is an American-European interplanetary spacecraft intended to carry a crew of four astronauts to destinations at or beyond low Earth orbit (LEO). Currently under development by the National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) for launch on the Space Launch System, Orion is intended to facilitate human exploration of the Moon, asteroids and of Mars and to retrieve crew or supplies from the International Space Station if needed.

The Orion MPCV was announced by NASA on May 24, 2011, and is currently under development. Its design is based on the Orion Crew Exploration Vehicle from the cancelled Constellation program. It has two main modules. The Orion command module is being built by Lockheed Martin at the Michoud Assembly Facility in New Orleans. The Orion service module, provided by the European Space Agency, is being built by Airbus Defence and Space.

The MPCV's first test flight (uncrewed), known as Exploration Flight Test 1 (EFT-1), was launched atop a Delta IV Heavy rocket on December 5, 2014, on a flight lasting 4 hours and 24 minutes, landing at its target in the Pacific Ocean at 10:29 Central (delayed from the prior day due to technical and weather problems). The first mission to carry astronauts is not expected to take place until 2023 at the earliest, although NASA officials have said that their staff is working toward an "aggressive internal goal" of 2021. However, a July 2016 Government Accountability Office report cast doubt on even the 2023 launch date, suggesting it may slip up to six months. The report gave only a 40% confidence in the 2021 launch date, and suggested the aggressive goal may be counterproductive to the program.

History

Funding history and planning

For fiscal years 2006 through 2018, the Orion program had expended funding totaling $15,983 million in nominal dollars. This is equivalent to $18,138 million adjusting to 2018 dollars using the NASA New Start Inflation Indices.

2006-2018 Total $15,983

Excluded from the prior Orion costs are:
  1. Costs "for production, operations, or sustainment of additional crew capsules, despite plans to use and possibly enhance this capsule after 2021"
  2. Costs of the first service module and spare parts to be provided by the European Space Agency for the test flight of Orion in 2020 (about $1 billion)
  3. Costs to assemble, integrate, prepare and launch the Orion and its launcher (funded under the NASA Ground Operations Project, currently about $400M per year)
  4. Costs of the launcher, the SLS, for the Orion spacecraft
For 2019 to 2023, NASA "notional" yearly budgets for Orion range from $1.1 to $1.2 billion. As of late 2015, the Orion program has a 70% confidence level for its “first Orion mission with astronauts by 2023” according to the Associate Administrator for NASA, Robert Lightfoot.

There are no NASA estimates for the Orion program recurring yearly costs once operational, for a certain flight rate per year, or for the resulting average costs per flight. Bill Hill, NASA manager of exploration systems development has indicated “My top number for Orion, SLS, and the ground systems that support it is $2 billion or less” (annually). NASA associate administrator William H. Gerstenmaier has indicated, “[per mission] costs must be derived from the data and are not directly available. This was done by design to lower NASA's expenditures.”

Orion Crew Exploration Vehicle (CEV)

Orion CEV design as of 2009.
 
On January 14, 2004, U.S. President George W. Bush announced the Crew Exploration Vehicle (CEV) as part of the Vision for Space Exploration. The CEV was partly a reaction to the Space Shuttle Columbia accident, the subsequent findings and report by the Columbia Accident Investigation Board (CAIB), and the White House's review of the American space program. The CEV effectively replaced the conceptual Orbital Space Plane (OSP), which was proposed after the cancellation of the Lockheed Martin X-33 program to produce a replacement for the Space Shuttle. As the Vision for Space Exploration was developed into the Constellation program under NASA administrator Sean O'Keefe, the Crew Exploration Vehicle was renamed the Orion Crew Exploration Vehicle, after the stellar constellation of the same name.

Constellation proposed using the Orion CEV in both crew and cargo variants to support the International Space Station and as a crew vehicle for a return to the Moon. The Apollo-like design included a service module for life support and propulsion and the crew/command module was originally intended to land on solid ground on the US west coast using airbags, but later changed to ocean splashdown. The Orion CEV weighs about 23 tonnes, less than the 30 tonne Apollo command and service module. The crew module would weigh about 8.9 tonnes, greater than the equivalent Apollo command module at 5.8 tonnes. With a diameter of 5 metres as opposed to 3.9 metres, the Orion CEV would provide 2.5 times greater volume as compared to the Apollo CM. The service module was originally planned to use liquid methane (LCH4) as its fuel, but switched to hypergolic propellants due to the infancy of oxygen/methane-powered rocket technologies and the goal of launching the Orion CEV by 2012.

The Orion CEV design consisted of two main parts: a conical crew module (CM) and a cylindrical service module (SM) holding the spacecraft's propulsion system and expendable supplies. Both were based substantially on the Apollo command and service modules flown between 1967 and 1975.

The Orion CEV was to be launched on the Ares I rocket to low Earth orbit, where it would rendezvous with the Altair lunar surface access module (LSAM) launched on a heavy-lift Ares V launch vehicle for lunar missions.

Cancellation of Constellation program

Artist's conception of the Orion spacecraft as then designed in lunar orbit.
 
On May 7, 2009, the Obama administration enlisted the Augustine Commission to perform a full independent review of the ongoing NASA space exploration program. The commission found the then current Constellation Program to be woefully under-budgeted, behind schedule by four years or more in several essential components, with significant cost overruns, and unlikely to be capable of meeting any of its scheduled goals under its current budget. As a consequence, the commission recommended a significant re-allocation of goals and resources. As one of the many outcomes based on these recommendations, on October 11, 2010, the Constellation program was cancelled, ending development of the Altair, Ares I, and Ares V. The Orion Crew Exploration Vehicle survived the cancellation and was renamed the Multi-Purpose Crew Vehicle (MPCV), to be launched on the Space Launch System.

Orion Multi-Purpose Crew Vehicle (MPCV)

Through the program restructuring from Constellation to Post Constellation, the Orion development program moved from the development of three different versions of the Orion capsule, each for a different task, to the development of a single version capable of performing multiple tasks. On October 30, 2014, the somewhat redesigned Multi-Purpose spacecraft completed its first flight readiness review (FRR), allowing the vehicle to be integrated with the Delta IV rocket and readied for launch. On December 5, 2014 it was successfully launched into space and retrieved at sea after splashdown on the Exploration Flight Test 1 (EFT-1), marking NASA's re-entry into the business of designing and producing new crewed spacecraft.

Asteroid Redirect Mission

This mission would have placed an asteroid in lunar orbit, rather than sending astronauts to an asteroid in deep space. It was a part of the FY2014 budget request. Originally planned for 2017, then 2020, and then for December 2021, the mission was given its notice of defunding in April 2017. The launch vehicle would have been either a Delta IV Heavy, SLS or Falcon Heavy. The boulder would have arrived in lunar orbit by late 2025, where it was to be further analyzed both by robotic probes and by a future crewed mission called ARCM (Asteroid Redirect Crewed Mission).

The development of advanced solar electric propulsion technology originally meant for this mission continues for its potential application on the proposed Lunar Orbital Platform-Gateway.

Design

The Orion MPCV takes basic design elements from the Apollo command module that took astronauts to the Moon, but its technology and capability are more advanced. It is designed to support long-duration deep space missions, with up to 21 days active crew time plus 6 months quiescent. During the quiescent period crew life support would be provided by another module such as a Deep Space Habitat. The spacecraft's life support, propulsion, thermal protection, and avionics systems are designed to be upgradeable as new technologies become available. 

The MPCV spacecraft includes both crew and service modules, and a spacecraft adaptor. 

The MPCV's crew module is larger than Apollo's and can support more crew members for short or long-duration missions. The service module fuels and propels the spacecraft as well as storing oxygen and water for astronauts. The service module's structure is also being designed to provide locations to mount scientific experiments and cargo.

Crew module (CM)

The Orion crew module (CM) is the reusable transportation capsule that provides a habitat for the crew, provides storage for consumables and research instruments, and serves as the docking port for crew transfers. The crew module is the only part of the MPCV that returns to Earth after each mission and is a 57.5° frustum shape, similar to that of the Apollo command module. As projected, the CM will be 5.02 meters (16 ft 6 in) in diameter and 3.3 meters (10 ft 10 in) in length, with a mass of about 8.5 metric tons (19,000 lb). It was manufactured by the Lockheed Martin Corporation. It will have more than 50% more volume than the Apollo capsule, which had an interior volume of 5.9 m3 (210 cu ft), and will carry four to six astronauts. After extensive study, NASA has selected the Avcoat ablator system for the Orion crew module. Avcoat, which is composed of silica fibers with a resin in a honeycomb made of fiberglass and phenolic resin, was formerly used on the Apollo missions and on select areas of the space shuttle for early flights.

Orion's CM will use advanced technologies, including:
  • "Glass cockpit" digital control systems derived from those of the Boeing 787 Dreamliner.
  • An "autodock" feature, like those of Russian Progress spacecraft, the European Automated Transfer Vehicle, and the SpaceX Dragon 2, with provision for the flight crew to take over in an emergency. Prior American spacecraft (Gemini, Apollo, and Space Shuttle) have all needed manual piloting for docking.
  • Improved waste-management facilities, with a miniature camping-style toilet and the unisex "relief tube" used on the space shuttle (whose system was based on that used on Skylab) and the International Space Station (based on the Soyuz, Salyut, and Mir systems). This eliminates the use of the much-hated plastic "Apollo bags" used by the Apollo crews.
  • A nitrogen/oxygen (N
    2
    /O
    2
    ) mixed atmosphere at either sea level (101.3 kPa or 14.69 psi) or reduced (55.2 to 70.3 kPa or 8.01 to 10.20 psi) pressure.
  • Far more advanced computers than on prior crew vehicles.
The CM will be built of the aluminium-lithium alloy used on the Space Shuttle external tank, and the Delta IV and Atlas V rockets. The CM will be covered in the same Nomex felt-like thermal protection blankets used on parts on the shuttle not subject to critical heating, such as the payload bay doors. The reusable recovery parachutes will be based on the parachutes used on both the Apollo spacecraft and the Space Shuttle Solid Rocket Boosters, and will also use Nomex cloth for construction. Water landings will be the exclusive means of recovery for the Orion CM.

To allow Orion to mate with other vehicles, it will be equipped with the NASA Docking System, which is somewhat similar to the APAS-95 docking mechanism used on the Shuttle fleet. The spacecraft will employ a Launch Escape System (LES) like that used in Mercury and Apollo, along with an Apollo-derived "Boost Protective Cover" (made of fiberglass), to protect the Orion CM from aerodynamic and impact stresses during the first ​2 12 minutes of ascent. Its designers claim that the MPCV is designed to be 10 times safer during ascent and reentry than the Space Shuttle. The CM is designed to be refurbished and reused. In addition, all of the Orion's component parts have been designed to be as generic as possible, so that between the craft's first test flight in 2014 and its projected Mars voyage in the 2030s, the spacecraft can be upgraded as new technologies become available.

ATV-based European service module (ESM)

In May 2011 the ESA director general announced a possible collaboration with NASA to work on a successor to the ATV (Automated Transfer Vehicle). On June 21, 2012, Airbus Defence and Space announced that they had been awarded two separate studies, each worth €6.5 million, to evaluate the possibilities of using technology and experience gained from ATV and Columbus related work for future missions. The first looked into the possible construction of a service module which would be used in tandem with the Orion capsule. The second examined the possible production of a versatile multi purpose orbital vehicle.

On November 21, 2012, the ESA decided to develop an ATV-derived service module for the Orion MPCV. The service module is being manufactured by Airbus Defence and Space in Bremen, Germany. NASA announced on January 16, 2013 that the ESA service module will first fly on Exploration Mission 1, the debut launch of the Space Launch System.

Testing of the European service module began in February 2016, at the Space Power Facility.

On 16 February 2017 a €200m contract was signed between Airbus and the European Space Agency for the production of a second European service module for use on the first crewed Orion flight, called Exploration Mission-2 (EM-2).

Launch Abort System (LAS)

In the event of an emergency on the launch pad or during ascent, a launch escape system called the Launch Abort System (LAS) will separate the crew module from the launch vehicle using a solid rocket-powered launch abort motor (AM), which will produce more thrust (though for a much shorter duration) than the Atlas 109-D booster that launched astronaut John Glenn into orbit in 1962. There are two other propulsion systems in the LAS stack: the attitude control motor (ACM) and the jettison motor (JM). The ACM is a thruster system on the escape tower used to position and orient the capsule. The jettison motor is a solid rocket system used to separate the LAS from the crew capsule. On July 10, 2007, Orbital Sciences, the prime contractor for the LAS, awarded Alliant Techsystems (ATK) a $62.5 million sub-contract to, "design, develop, produce, test and deliver the launch abort motor." ATK, which had the prime contract for the first stage of the Ares I rocket, intended to use a "reverse flow" design for the motor. On July 9, 2008, NASA announced that ATK had completed a vertical test stand at a facility in Promontory, Utah to test launch abort motors for the Orion spacecraft. Another long-time space motor contractor, Aerojet, was awarded the jettison motor design and development contract for the LAS. As of September 2008, Aerojet has, along with team members Orbital Sciences, Lockheed Martin and NASA, successfully demonstrated two full-scale test firings of the jettison motor. This motor is important to every flight in that it functions to pull the LAS tower away from the vehicle after a successful launch. The motor also functions in the same manner for an abort scenario.

Existing craft mockups and testing

  • Space Vehicle Mockup Facility (SVMF) in Johnson Space Center, includes a full-scale Orion capsule mock-up for astronaut training.
  • Exploration Flight Test 1 (EFT-1) Orion (originally designated OFT-1), constructed at Michoud Assembly Facility, was delivered by Lockheed Martin to the Kennedy Space Center on July 2, 2012 and launched and recovered on December 5, 2014.
  • The Boilerplate Test Article (BTA) underwent splashdown testing at the Hydro Impact Basin of NASA's Langley Research Center. This same test article has been modified to support Orion Recovery Testing in the Stationary and Underway recovery tests. The BTA contains over 150 sensors to gather data on its test drops. Testing of the 18,000 pound mockup ran from July 2011 to January 6, 2012.
  • The Ground Test Article (GTA) stack, located at Lockheed Martin in Denver, is undergoing vibration testing. It is made up by the Orion Ground Test Vehicle (GTV) combined with its Launch Abort System (LAS). Further testing will see the addition of service module simulator panels and Thermal Protection System (TPS) to the GTA stack.

  • The Drop Test Article (DTA), also known as the Drop Test Vehicle (DTV) is undergoing test drops at the US Army's Yuma Proving Ground in Arizona. The mock Orion parachute compartment is dropped from an altitude of 25,000 feet from a C-130. Testing began in 2007. Drogue chutes deploy around 20,000 and 15,000 feet. Testing of the reefing staged parachutes includes partial failure instances including partial opening and complete failure of one of the three main parachutes. With only two chutes deployed the DTA lands at 33 feet per second, the maximum touchdown speed for Orion's design. Other related test vehicles include the now-defunct Orion Parachute Test Vehicle (PTV) and its replacement the Generation II Parachute Test Vehicle (PTV2). The drop test program has had several failures in 2007, 2008, and 2010. The new PTV was successfully tested February 29, 2012 deploying from a C-17. Ten drag chutes will drag the mockup's pallet from the aircraft for the drop at 25,000 feet. The landing parachute set of eight is known as the Capsule Parachute Assembly System (CPAS). The test examined air flow disturbance behind the mimicked full size vehicle and its effects on the parachute system. The PTV landed on the desert floor at 17 mph (7.6 m/s). A third test vehicle, the PCDTV3, was successfully tested in a drop on April 17, 2012. "The test examined how Orion's wake, the disturbance of the air flow behind the vehicle, would affect the performance of the parachute system."

Environmental testing

NASA performed environmental testing of Orion from 2007 to 2011 at the Glenn Research Center Plum Brook Station in Sandusky, Ohio. The Center's Space Power Facility is the world's largest thermal vacuum chamber.

Launch abort system (LAS) testing

ATK Aerospace successfully completed the first Orion Launch Abort System (LAS) test on November 20, 2008. The LAS motor could provide 500,000 lbf (2,200 kN) of thrust in case an emergency situation should arise on the launch pad or during the first 300,000 feet (91 km) of the rocket's climb to orbit. The 2008 test firing of the LAS was the first time a motor with reverse flow propulsion technology of this scale had ever been tested.

On March 2, 2009, a full size, full weight command module mockup (pathfinder) began its journey from the Langley Research Center to the White Sands Missile Range, New Mexico, for at-gantry launch vehicle assembly training and for LAS testing. On May 10, 2010, NASA successfully executed the LAS PAD-Abort-1 test at White Sands New Mexico, launching a boilerplate (mock-up) Orion capsule to an altitude of approximately 6000 feet. The test used three solid-fuel rocket motors – a main thrust motor, an attitude control motor and the jettison motor.

Future LAS test plans: As of April 2018, NASA planned to launch the Orion Multi Purpose Crew Vehicle Ascent Abort 2 test flight (AA‑2) from the Spaceport Florida Launch Complex 46 in 2019.

Pre-launch Orion splashdown recovery testing

Before the first test flight and recovery of the Orion space vehicle at sea in December 2014, several preparatory vehicle recovery tests were performed. In 2009 during the Constellation phase of the program, the Post-landing Orion Recovery Test (PORT) was designed to determine and evaluate methods of crew rescue and what kind of motions the astronaut crew could expect after landing. This would include conditions outside the capsule for the recovery team. The evaluation process supported NASA's design of landing recovery operations including equipment, ship and crew needs. 

The PORT Test used a full-scale boilerplate (mock-up) of NASA's Orion crew module and was tested in water under simulated and real weather conditions. Tests began March 23, 2009 with a Navy-built, 18,000-pound boilerplate when it was placed in a test pool at the Naval Surface Warfare Center's Carderock Division in West Bethesda, Md. Full sea testing ran April 6–30, 2009, at various locations off the coast of NASA's Kennedy Space Center with media coverage.

Under the Orion program testing, Orion continued the "crawl, walk, run" approach used in PORT testing. The "crawl" phase was performed August 12–16, 2013 with the Stationary Recovery Test (SRT). The Stationary Recovery Test demonstrated the recovery hardware and techniques that were to be employed for the recovery of the Orion crew module in the protected waters of Naval Station Norfolk utilizing the USS Arlington as the recovery ship. The USS Arlington is a LPD 17 amphibious assault ship. The recovery of the Orion crew module will utilize unique features of the LPD 17 class ship to safely and economically recover the Orion crew module and eventually its astronaut crew.

The "walk" and "run" phases were performed with the Underway Recovery Test (URT). Also utilizing the LPD 17 class ship, the URT were performed in more realistic sea conditions off the coast of California in early 2014 to prepare the US Navy / NASA team for recovering the Exploration Flight Test 1 (EFT-1) Orion crew module. The URT tests completed the pre-launch test phase of the Orion recovery system.

Exploration Flight Test 1

EFT-1
 
At 7:05 AM EST on December 5, 2014 the Orion capsule was launched atop a Delta IV Heavy rocket for its first test flight, and splashed down in the Pacific Ocean about 4.5 hours later. Although it was not crewed, the two-orbit flight was NASA's first launch of a human-rated vehicle since the retirement of the Space Shuttle fleet in 2011. Orion reached an altitude of 3,600 mi (5,800 km) and speeds of up to 20,000 mph (8,900 m/s) on a flight that tested Orion's heat shield, parachutes, jettisoning components, and on-board computers. Orion was recovered by USS Anchorage and brought to San Diego, California for its return to Kennedy Space Center in Florida.

Orion program mission schedule

As of July 2018, the first flight of NASA's next-generation heavy-lift rocket, the Space Launch System (SLS), is scheduled for mid-2020 for an Orion lunar flyby mission called Exploration Mission-1 (EM-1), but it will not include a human crew. Although NASA has always planned for the first flight of the SLS to take place without a crew on board, the Trump administration's transition team asked, in early 2017, for an internal evaluation of the possibility of making it a crewed flight. Robert Lightfoot, then NASA's acting administrator, said "based on the results of this internal evaluation, a crewed flight would be technically feasible, but the agency will proceed with its initial plan to make the rocket's first flight uncrewed." 

The Lunar Orbital Platform-Gateway (LOP-G) is a proposed space station in lunar orbit intended to serve as an all-in-one solar-powered communications hub, science laboratory, short-term habitation module, and staging area for rovers and other robots. Various components of the Gateway would be launched on commercial launch vehicles and on the Space Launch System as Orion co-manifested payloads on the flights EM-3 through EM-9.\

Mars missions

The Orion capsule is designed to support future missions to send astronauts to Mars, probably to take place in the 2030s. Since the Orion capsule provides only about 2.25 m3 (79 cu ft) of living space per crew member, the use of an additional Deep Space Habitat module will be needed for long duration missions. The habitat module will provide additional space and supplies, as well as facilitate spacecraft maintenance, mission communications, exercise, training, and personal recreation. Some plans for DSH modules would provide approximately 70.0 m3 (2,472 cu ft) of living space per crew member, though the DSH module is currently only in its early planning stages. DSH sizes and configurations may vary slightly, depending on crew and mission needs. The mission is planned to launch in 2033.
