Full sea testing ran April 6–30, 2009, at various locations off the coast of NASA's Kennedy Space Center with media coverage. 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 with significant cost overruns, behind schedule by four years or more in several essential components, and unlikely to be capable of meeting any of its scheduled goals. As

720-584: A Science Platform", and "Design of a Gateway-Based Cislunar Tug". Teams of undergraduate and graduate students were asked to submit a response by 17 January 2019 addressing one of these four themes. NASA selected 20 teams to continue developing proposed concepts. Fourteen of the teams presented their projects in person in June 2019 at the RASC-AL Forum in Cocoa Beach, Florida, receiving a US$ 6,000 stipend to participate in

810-552: A boilerplate (mock-up) Orion capsule to an altitude of approximately 6,000 feet (1,800 m). The test used three solid-fuel rocket motors – the main thrust motor, an attitude control motor and the jettison motor. 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

900-536: 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 canceled, ending development of the Altair, Ares I, and Ares V. The Orion Crew Exploration Vehicle survived the cancellation and was transferred to be launched on the Space Launch System. The Orion development program

990-471: A contributor to The Hill newspaper and an author of several space exploration studies, stated in an article that the "lunar orbit project doesn't help us get back to the Moon". Whittington also pointed out that a lunar orbiting space station was not used during the Apollo program and that a "reusable lunar lander could be refueled from a depot on the lunar surface and left in a parking orbit between missions without

1080-518: A crew vehicle for a return to the Moon. 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, while a service module was included for life support and propulsion. With a diameter of 5 meters (16 ft 5 in) as opposed to 3.9 meters (12 ft 10 in), the Orion CEV would have provided 2.5 times greater volume than

1170-584: A future destination, as someone who lived on the ISS for 200 days, I cannot envision a new technology that would be developed or validated by building another modular space station. Without a specific goal, we're unlikely to ever identify one". Virts further criticized NASA for abandoning its planned goal of separating crew from cargo, which was put in place following the Space Shuttle Columbia disaster in 2003. Apollo 11 astronaut Buzz Aldrin stated that he

1260-641: A heavy-lift Ares V launch vehicle for lunar missions. 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 . 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

1350-498: A jettison motor (JM). The AM provides the thrust needed to accelerate the capsule, while the ACM is used to point the AM and the jettison motor separates 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," which uses

1440-520: A large near-Earth asteroid and use robotic arms with anchoring grippers to retrieve a 4-meter boulder from the asteroid. A secondary objective was to develop the required technology to bring a small near-Earth asteroid into lunar orbit – "the asteroid was a bonus." There, it could be analyzed by the crew of the Orion EM-5 or EM-6 ARCM mission in 2026. [REDACTED]  This article incorporates public domain material from websites or documents of

1530-410: A lightweight crew capsule proposed by Bigelow Aerospace in collaboration with Lockheed Martin. It was to be based on the Orion spacecraft that Lockheed Martin was developing for NASA. It was never developed. It was to be a lighter, less capable and a less expensive version of the full Orion. Orion Lite was intended to provide a stripped-down version of the Orion that would be available for missions to

1620-435: A lunar flyby. Flights are expected to achieve a yearly cadence from Artemis IV onward in 2028. A proposal curated by William H. Gerstenmaier before his 10 July 2019 reassignment suggests four launches of the crewed Orion spacecraft and logistical modules aboard the SLS Block 1B to the Gateway. The crewed Artemis   4 through   7 would launch yearly, testing in situ resource utilization and nuclear power on

1710-585: A narrow corridor and a total of 1.5 cubic meters (53 cubic feet) of personal space to be shared by four astronauts. Mars Society founder Robert Zubrin called the Gateway "NASA's worst plan yet" in an article in the National Review . He said, "We do not need a lunar-orbiting station to go to the Moon . We do not need such a station to go to Mars . We do not need it to go to near-Earth asteroids . We do not need it to go anywhere. Nor can we accomplish anything in such

1800-564: A number of ways. For example, the FTA did not have a crew on board, and the avionics were a prototype of what is planned for production Orions. The PA-1 test took place on 6 May 2010 at the U.S. Army's White Sands Missile Range in New Mexico . It was also the final flight done under the auspice of the Constellation program before it was cancelled. The Orion capsule used in the test is on display at

1890-605: A part of the now-canceled Asteroid Redirect Mission . On 7 November 2017, NASA asked the global science community to submit concepts for scientific studies that could take advantage of the Deep Space Gateway's location in cislunar space. The Deep Space Gateway Concept Science Workshop was held in Denver, Colorado, from 27 February to 1 March 2018. This three-day conference was a workshop where 196 presentations were given for possible scientific studies that could be advanced through

1980-519: A similar capsule, the CST-100 , which has no Orion heritage, and was one of the two systems selected under NASA's Commercial Crew Development (CCDev) program to transport crew to the ISS. Orion Lite's primary mission would be to transport crew to the International Space Station (ISS), or to private space stations such as the planned B330 from Bigelow Aerospace. While Orion Lite would have

2070-535: A space station to orbit it". Former NASA astronaut Terry W. Virts , who was a pilot of STS-130 aboard Space Shuttle Endeavour and commander of the ISS on Expedition 43 , wrote in an op-ed on Ars Technica that the Gateway would "shackle human exploration, not enable it". He also said, "If we don't have the goal [of Gateway], we are putting the proverbial chicken before the egg by developing " Gemini " before we know what " Apollo " will look like. Regardless of

2160-486: A station that we cannot do in the Earth-orbiting International Space Station , except to expose human subjects to irradiation – a form of medical research for which a number of Nazi doctors were hanged ". Zubrin also stated, "If the goal is to build a Moon base, it should be built on the surface of the Moon. That is where the science is, that is where the shielding material is, and that is where

2250-453: A total engine output fractionally under 50 kW. In 2019, the contract to manufacture the PPE was awarded to Maxar Technologies . After a one-year demonstration period, NASA intended to "exercise a contract option to take over control of the spacecraft". Its expected service time is about 15 years. In late 2023, it was reported that flight qualification testing was occurring on the thrusters for

2340-418: Is "quite opposed to the Gateway" and that "using the Gateway as a staging area for robotic or human missions to the lunar surface is absurd". Aldrin also questioned the benefit of the idea of sending "a crew to an intermediate point in space, pick up a lander there and go down". Conversely, Aldrin expressed support for Robert Zubrin 's Moon Direct concept which involves lunar landers traveling from Earth orbit to

2430-744: 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 Artemis I , the debut launch of the Space Launch System.

Water landing is 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 . The spacecraft employs

2610-786: 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 m (79 cu ft) of living space per crew member, the use of an additional Deep Space Habitat (DSH) module featuring propulsion will be needed for long-duration missions. The complete spacecraft stack is known as the Deep Space Transport . The habitat module will provide additional space and supplies, as well as facilitate spacecraft maintenance, mission communications, exercise, training, and personal recreation. Some concepts for DSH modules would provide approximately 70.0 m (2,472 cu ft) of living space per crew member, though

2700-502: Is following Space Policy Directive 1", speaking of the Gateway and following up with "I would argue that we got there in 1969. That race is over, and we won. The time now is to build a sustainable, reusable architecture. [...] The next time we go to the Moon, we're going to have American boots on the Moon with the American flag on their shoulders, and they're going to be standing side-by-side with our international partners who have never been to

2790-477: Is larger than Apollo 's and can support more crew members for short or long-duration missions. The European service module propels and powers the spacecraft as well as storing oxygen and water for astronauts. Orion relies on solar energy rather than fuel cells, which allows for longer missions. The Orion crew module (CM) is a reusable transportation capsule that provides a habitat for the crew, provides storage for consumables and research instruments, and contains

3600-399: The orbital inclination could be shifted with a relatively small Δ v expenditure, allowing access to most of the lunar surface. Spacecraft launched from Earth would perform a powered flyby of the Moon (Δ v ≈ 180 m/s) followed by a Δ v ≈ 240 m/s NRHO insertion burn to dock with the Gateway as it approaches the apoapsis point of its orbit. The total travel time would be 5 days;

3690-540: The "crawl, walk, run" approach established by PORT. The "crawl" phase was performed August 12–16, 2013, with the Stationary Recovery Test (SRT). The SRT demonstrated the recovery hardware and techniques that were to be employed for the recovery of the Orion CM in the protected waters of Naval Station Norfolk using the LPD-17 type USS Arlington as the recovery ship. The "walk" and "run" phases were performed with

3780-556: The Apollo CM. The service module was originally planned to use liquid methane (LCH 4 ) 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 was to be launched on the Ares I rocket to low Earth orbit, where it would rendezvous with the Altair lunar lander launched on

3870-535: The Apollo capsule and will carry four astronauts. After extensive study, NASA selected the Avcoat ablator system to provide heat protection encountered during reentry 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 the Space Shuttle orbiter for early flights. The CM uses Glass cockpit digital control systems derived from those of

3960-631: The DSH module is in its early conceptual stage. DSH sizes and configurations may vary slightly, depending on crew and mission needs. The mission may launch in the mid-2030s or late-2030s. The Asteroid Redirect Mission ( ARM ), also known as the Asteroid Retrieval and Utilization ( ARU ) mission and the Asteroid Initiative , was a space mission proposed by NASA in 2013. The Asteroid Retrieval Robotic Mission (ARRM) spacecraft would rendezvous with

4050-706: The Forum. The "Lunar Exploration and Access to Polar Regions", from the University of Puerto Rico at Mayagüez , was the winning concept. On 27 September 2017, an informal joint statement on cooperation regarding the program between NASA and Russia's Roscosmos was announced. However, in October 2020 Dmitry Rogozin , director general of Roscosmos, said that the program is too “U.S.-centric” for Roscosmos to participate, and in January 2021, Roscosmos announced that it would not participate in

4140-595: The Gateway, with just with one logistics module, we think we can extend to about twice the mission duration, so 30 days to 60 days. Obviously, the more crew time you have in lunar orbit helps us with research in the human aspects of living in deep space. The more duration we have, certainly that'll help us buy down significant risk with the extreme environments that we're going to be subjecting our crews to. Because we've got to go figure out how to operate in deep space. Obviously we'll demonstrate new hardware and offer that sustainable flexible path for our Lunar Lander system. With

4230-486: The Gateway. Griffin thinks that after that is achieved, the Gateway would then serve as a fuel depot. In a written testimony to Congress, Griffin stated that the current architecture requiring staging operations at a Gateway based in a lunar polar near-rectlinear halo orbit (NRHO) with a 6.5-day period was disadvantageous in that immediate return to the Gateway from the lunar surface is possible only on 6.5-day centers and that no early human lunar mission should knowingly accept

4320-510: The International Space Station earlier than the more capable Orion, which is designed for longer duration missions to the Moon and Mars . Bigelow had begun working with Lockheed Martin in 2004. A few years later Bigelow signed a million-dollar contract to develop "an Orion mockup, an Orion Lite", in 2009. The proposed collaboration between Bigelow and Lockheed Martin on the Orion Lite spacecraft has ended. Bigelow began work with Boeing on

4410-451: The Moon before". Dan Hartman, the program manager for Gateway, on 30 March 2020, told Ars Technica that the benefits of using Gateway are extending the mission duration, buying down risk, providing research capability and the capability to re-use ascent modules. When you go single, I'll say direct mission to the Moon, you're limited on the supplies, either with the Lander or with Orion. With

4500-596: The Orion program had expended funding totaling $ 22.9 billion in nominal dollars. This is equivalent to $ 29.4 billion in 2024 dollars using the NASA New Start Inflation Indices. In 2024, the US Congress approved "up to" $ 1.339 billion for the NASA Orion spacecraft. Excluded from the prior Orion costs are: For 2021 to 2025, NASA estimates yearly budgets for Orion from $ 1.4 to $ 1.1 billion. In late 2015,

4590-490: The Orion program was assessed at a 70% confidence level for its first crewed flight by 2023, but in January of 2024 NASA announced plans for a first crewed flight of Orion no earlier than September 2025. 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. However, a production and operations contract awarded to Lockheed Martin in 2019 indicated NASA will pay

5580-429: The lander elements (ascent and descent/transfer) on an SLS Block 1B. If an independent transfer element is required, it can be launched on a commercial launcher". George Abbey , a former director of NASA's Johnson Space Center , said, "The Gateway is, in essence, building a space station to orbit a natural space station, namely the Moon. [...] If we are going to return to the Moon, we should go directly there, not build

5670-444: The launch pad or during the first 300,000 feet (91 km) of the rocket's climb to orbit. On March 2, 2009, a full size, full weight command module mockup (pathfinder) began its journey from the Langley Research Center to White Sands Missile Range in southern New Mexico for at-gantry launch vehicle assembly training and for LES testing. On May 10, 2010, NASA successfully executed the LES PAD-Abort-1 test at White Sands, launching

5760-571: The lunar surface and back. Architect René Waclavicek, who was involved with the design of the I-HAB module, noted the difficulty of designing a comfortable living quarter for astronauts visiting Gateway. His team was forced to shrink the size of the module to the point where its diameter is just 1.2 meters (4 feet), owing to the limited amount of weight current launch vehicles can carry to Lunar orbit and other technical limits. Additionally, most of I-HAB's 8 cubic meters (280 cubic feet) of available space will be filled with life support equipment, leaving

5850-403: The lunar surface with a partially reusable lander. Artemis   7 would deliver a crew of four astronauts to a surface lunar outpost known as the Lunar Surface Asset. The Lunar Surface Asset would be launched by an undetermined launcher and would be used for extended crewed lunar surface missions. Another repair mission to the Hubble Space Telescope is also possible. The Orion capsule

5940-443: The lunar surface", reducing the time delay. His final opinion was that the Gateway is "a great way to spend a great deal of money, advancing science and humanity in no appreciable way". On 10 December 2018, NASA Administrator Jim Bridenstine said at a presentation "There are people who say we need to get there, and we need to get there tomorrow", speaking of a crewed mission to the Moon, countering with "What we're doing here at NASA

6030-498: The more durable heat shield of the Orion would be replaced with a lighter weight heat shield designed to support the lower temperatures of Earth atmospheric re-entry from low Earth orbit. Additionally, the current proposal calls for a mid-air retrieval , wherein another aircraft captures the descending Orion Lite module. To date, such a retrieval method has not been employed for crewed spacecraft, although it has been used with satellites . The first crewed flight, Artemis II , will be

6120-429: The need for a big, complex space station". Astrophysicist Ethan Siegel wrote an article in Forbes titled "NASA's Idea For A Space Station In Lunar Orbit Takes Humanity Nowhere". Siegel stated that "Orbiting the Moon represents barely incremental progress; the only scientific "advantages" to being in lunar orbit as opposed to low Earth orbit are twofold: 1. You're outside of the Van Allen belts . 2. You're closer to

6210-478: The ongoing set of NextSTEP-2 awards made in 2016 to study development and make ground prototypes of habitat modules that could be used on the Gateway as well as other commercial applications, so the Gateway is likely to incorporate components developed under NextSTEP as well. The PPE will use four 6 kW BHT-6000 Busek Hall-effect thrusters and three 12 kW NASA / Aerojet Rocketdyne Advanced Electric Propulsion System (AEPS) Hall-effect thrusters for

For supporting the first crewed mission to the station ( Artemis IV ) planned for 2028, the Gateway will begin as a minimal space station composed of only two modules: the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO). Both PPE and HALO will be assembled on Earth and launched together on

6390-442: 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 CM. 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 Orion. The service module

6480-419: The prime contractor $ 900 million for the first three Orion capsules and $ 633 million for the following three. In 2016, the NASA manager of exploration systems development said that Orion, SLS, and supporting ground systems should cost "US$ 2 billion or less" annually. NASA will not provide the cost per flight of Orion and SLS, with associate administrator William H. Gerstenmaier stating "costs must be derived from

6570-601: The production of a second European service module for use on the first crewed Orion flight, Artemis II . On October 26, 2018, the first unit for Artemis I was assembled in full at Airbus Defence and Space's factory in Bremen, Germany. In the event of an emergency on the launch pad or during ascent, the Launch Abort System (LAS) will separate the crew module from the launch vehicle using three solid rocket motors: an abort motor (AM), an attitude control motor (ACM), and

6660-512: The program. As of January 2024, the Canadian Space Agency (CSA), the European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA) and Mohammed Bin Rashid Space Centre (MBRSC) plan to participate in the Gateway project, each contributing a robotic arm called Canadarm3 (CSA), refuelling and communications hardware, habitation and research capacity and an airlock module. These international elements are intended to launch after

6750-445: The project. While the project is led by NASA, the Gateway is meant to be developed, serviced, and used in collaboration with the CSA , ESA , JAXA , and commercial partners. It will serve as the staging point for both robotic and crewed exploration of the lunar south pole and is the proposed staging point for NASA's Deep Space Transport concept for transport to Mars. Formerly known as

6840-416: The quiescent period, crew life support would be provided by another module, such as the proposed Lunar Gateway . The spacecraft's life support, propulsion, thermal protection, and avionics systems can be upgraded as new technologies become available. At launch, the Orion spacecraft includes both crew and service modules, a spacecraft adapter and an emergency launch abort system. The Orion 's crew module

6930-469: The resources to make propellant and other useful things are to be found". Retired aerospace engineer Gerald Black wrote in an article on The Space Review stating that the Gateway is "useless for supporting human return to the lunar surface and a lunar base". He added that it was not planned to be used as a rocket fuel depot and that stopping at the Gateway on the way to or from the Moon would serve no useful purpose and cost propellant. Mark Whittington,

7020-436: The return to Earth would be similar in terms of trip duration and Δ v requirement if the spacecraft spends 11 days at the Gateway. The crewed mission duration of 21 days and Δ v ≈ 840 m/s is limited by the capabilities of the Orion life support and propulsion systems. Gateway will be the first modular space station to be both human-rated, and autonomously operating most of the time in its early years, as well as being

7110-644: The risk of stranding a crew, whether on the surface or in lunar orbit, for days at a time. Clive Neal, a University of Notre Dame geologist and advocate for the lunar exploration program, called the Gateway "a waste of money" and stated that NASA is "not fulfilling space policy by building an orbital space station around the Moon". Former NASA Associate Administrator Doug Cooke wrote in an article on The Hill stating, "NASA can significantly increase speed, simplicity, cost and probability of mission success by deferring Gateway, leveraging SLS, and reducing critical mission operations". He also wrote, "NASA should launch

7200-422: The same exterior dimensions as the Orion, there would be no need for the deep space infrastructure present in the Orion configuration. As such, the Orion Lite would have been able to support larger crews of around 7 people as the result of greater habitable interior volume and the reduced weight of equipment needed to support an exclusively low-Earth-orbit configuration. In order to reduce the weight of Orion Lite,

7290-535: The spacecraft's primary propulsion, while eight R-4D-11 engines, and six pods of custom reaction control system engines developed by Airbus, provide the spacecraft's secondary propulsion. Orion is intended to be launched atop a Space Launch System (SLS) rocket, with a tower launch escape system . Orion was conceived in the early 2000s by Lockheed Martin as a proposal for the Crew Exploration Vehicle (CEV) to be used in NASA's Constellation program and

7380-511: The use of the Gateway. In 2018, NASA initiated the Revolutionary Aerospace Systems Concepts Academic Linkage (RASC-AL) competition for universities to develop concepts and capabilities for the Gateway. The competitors were asked to employ original engineering and analysis in one of four areas; "Gateway Uncrewed Utilization and Operations", "Gateway-Based Human Lunar Surface Access", "Gateway Logistics as

7470-586: Was announced by NASA on May 24, 2011. Its design is based on the Crew Exploration Vehicle from the canceled Constellation program , which had been a 2006 NASA contract award to Lockheed Martin. The command module is being built by Lockheed Martin at the Michoud Assembly Facility , while the Orion service module is being built by Airbus Defence and Space in Bremen with funding from the European Space Agency. The CM's first uncrewed test flight (EFT-1)

7560-523: Was dubbed the Deep Space Habitat . That proposal led to funding in 2015 under the NextSTEP program to study the requirements of deep space habitats. In February 2018, it was announced that the NextSTEP studies and other ISS partner studies would help to guide the capabilities required of the Gateway's habitation modules. The solar electric Power and Propulsion Element (PPE) of the Gateway was originally

7650-471: Was held, and the winner was the proposal from a consortium led by Lockheed Martin. It was later named "Orion" after the stellar constellation and mythical hunter of the same name, and became part of the Constellation program under NASA administrator Sean O'Keefe . Constellation proposed using the Orion CEV in both crew and cargo variants to support the International Space Station and as

7740-595: Was launched in 2014 during Exploration Flight Test-1 , while at least four test articles were produced. Orion was primarily designed by Lockheed Martin Space Systems in Littleton, Colorado , with former Space Shuttle engineer Julie Kramer White at NASA as Orion's chief engineer. As of 2022 , three flight-worthy Orion spacecraft were under construction, with one completed and an additional one ordered, for use in NASA's Artemis program . The first completed unit, CM-002,

7830-436: Was launched on November 16, 2022, on Artemis I . Orion uses the same basic configuration as the Apollo command and service module (CSM) that first took astronauts to the Moon, but with an increased diameter, updated thermal protection system, and other more modern technologies. It is designed to support long-duration deep space missions with up to 21 days of active crew time plus 6 months' quiescent spacecraft life. During

7920-566: Was launched without the EUS atop a Delta IV Heavy rocket on December 5, 2014, and lasted 4 hours and 24 minutes before landing at its target in the Pacific Ocean . On November 30, 2020, it was reported that NASA and Lockheed Martin had found a failure with a component in one of the Orion spacecraft's power data units but NASA later clarified that it did not expect the issue to affect the Artemis I launch date. For fiscal years 2006 through 2023,

8010-634: Was restructured from three different versions of the Orion capsule, each for a different task, to the development of the MPCV as a single version capable of performing multiple tasks. On December 5, 2014, a developmental Orion spacecraft was successfully launched into space and retrieved at sea after splashdown on the Exploration Flight Test-1 (EFT-1). Before EFT-1 in December 2014, several preparatory vehicle recovery tests were performed, which continued

8100-410: Was selected by NASA in 2006. Following the cancellation of the Constellation program in 2010, Orion was extensively redesigned for use in NASA's Journey to Mars initiative; later named Moon to Mars. The SLS became Orion's primary launch vehicle, and the service module was replaced with a design based on the European Space Agency 's Automated Transfer Vehicle . A development version of Orion's crew module
