A single AJ10 engine provides 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. Although compatible with other launch vehicles, Orion is primarily intended to launch atop a Space Launch System (SLS) rocket, with a tower launch escape system. Orion was originally 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. Lockheed Martin's proposal defeated a competing proposal by Northrop Grumman and was selected by NASA in 2006 to be the CEV. Originally designed with a service module featuring a new "Orion Main Engine" and a pair of circular solar panels, the spacecraft was to be launched atop the Ares I rocket. Following the cancellation of the Constellation program in 2010, Orion was heavily redesigned for use in NASA's Journey to Mars initiative; later named Moon to Mars. The SLS replaced the Ares I as Orion's primary launch vehicle, and the service module was replaced with a design based on the

Spacecraft description

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 modern technologies. It will be capable of supporting long-duration deep space missions with up to 21 days of active crew time plus 6 months' quiescent spacecraft life. During the quiescent period crew life support would be provided by another module, such as the proposed

Deep Space Habitat The Deep Space Habitat (DSH) is a series of concepts by NASA that would be used to support crewed exploration missions to the Moon, asteroids, and eventually Mars. The Orion spacecraft includes both crew and service modules, a spacecraft adapter and an emergency launch abort system. The Orion crew module 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.

Crew module (CM)

Orion Spacecraft Outfitted Interior 2021 (no labels)

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 the docking port for crew transfers. The crew module is the only part of the spacecraft that returns to Earth after each mission and is a 57.5° frustum shape with a blunt spherical aft end, in diameter and in length, with a mass of about . It was manufactured by the Lockheed Martin Corporation at Michoud Assembly Facility in New Orleans. It will have 50% more volume than the Apollo capsule and will carry four to six astronauts. After extensive study, NASA has 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. Orion's CM will use advanced technologies, including: *

, for the Orion spacecraft For 2021 to 2025, NASA estimates yearly budgets for Orion from $1.4 to $1.1 billion. In late 2015, the Orion program was assessed at a 70% confidence level for its first crewed flight by 2023. 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 the prime contractor $900M for the first three Orion capsules and $633M 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 the data and are not directly available. This was done by design to lower NASA's expenditures" in 2017.

The idea for a Crew Exploration Vehicle (CEV) was announced on January 14, 2004, as part of the Vision for Space Exploration after the Space Shuttle ''Columbia'' accident. The CEV effectively replaced the conceptual Orbital Space Plane (OSP), a proposed replacement for the Space Shuttle. A design competition was held, and the winner was the proposal from a consortium led by Lockheed Martin. It was later named "Orion" after the stellar

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 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 as opposed to , the Orion CEV would have provided 2.5 times greater volume than 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 was to be launched on the Ares I rocket to low Earth orbit, where it would rendezvous with the Altair lunar lander launched on a heavy-lift

ATK Aerospace successfully completed the first Orion Launch Abort System (LAS) test on November 20, 2008. The LAS motor could provide of thrust in case an emergency situation should arise on the launch pad or during the first 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 the White Sands Missile Range, 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 New Mexico, launching a boilerplate (mock-up) Orion capsule to an altitude of approximately . The test used three solid-fuel rocket motorsthe main thrust motor, an attitude control motor and the jettison motor.

Splashdown recovery testing

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, including 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, boilerplate in a test pool. Full sea testing ran April 6–30, 2009, at various locations off the coast of NASA's Kennedy Space Center with media coverage.

Cancellation of Constellation program

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 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.

Orion Multi-Purpose Crew Vehicle (MPCV)

The Orion development program 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).

Orion splashdown recovery testing

Before EFT-1 in December 2014, several preparatory vehicle recovery tests were performed, which continued the "crawl, walk, run" approach established by PORT. 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 LPD-17 type USS Arlington as the recovery ship. The "walk" and "run" phases were performed with the Underway Recovery Test (URT). Also utilizing an LPD 17 class ship, the URT was 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. Delta IV Heavy on pad with Orion EFT-1 (KSC-2014-4686)

Orion Lite

History

Orion Lite is an unofficial name used in the media for a lightweight crew capsule proposed by Bigelow Aerospace in collaboration with

. It was to be based on the Orion spacecraft that Lockheed Martin was developing for NASA. It would be a lighter, less capable and cheaper version of the full Orion. The intention of designing Orion Lite would be to provide a stripped-down version of the Orion that would be available for missions to 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",Bigelow still thinks big
, '' The Space Review'', 2010-11-01, accessed 2010-11-02. " n October 2010Bigelow revealed that he had been working with Lockheed Martin on a capsule concept in the 2004–2005 period. 'We engaged in a million-dollar contract a couple years after that with Lockheed, and they created for us 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 a similar capsule, the CST-100, which has no Orion heritage, and was selected under NASA's Commercial Crew Development (CCDev) program to transport crew to the ISS.

Design

Orion Lite's primary mission would be to transport crew to the International Space Station, or to private space stations such as the planned B330 from Bigelow Aerospace. While Orion Lite would have 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 be 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.Space Hotel Visionary Proposes Modified "Orion Lite" Spaceship for NASA: Bigelow Airspace's concept is for low Earth-orbit missions only

Recovery

In order to reduce the weight of Orion Lite, 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.
