109-629: EGS holds and operates the following assets: EGS was originally entitled the Ground Systems Development and Operations ( GSDO ) Program. It has its roots in the Constellation program (2005-2010), but only took control of assets and commenced operations under SLS (from 2010). For example, after the final launch of the Space Shuttle , GSDO took responsibility for LC-39A . However, there were no plans to use this pad, and basic maintenance

218-521: A J-2X rocket engine. NASA selected the Ares designs for their anticipated overall safety, reliability and cost-efficiency. NASA began developing the Ares I low Earth orbit launch vehicle (analogous to Apollo's Saturn IB ), returning to a development philosophy used for the original Saturn I , test-launching one stage at a time, which George Mueller had firmly opposed and abandoned in favor of "all-up" testing for

327-542: A low Earth orbit by the Ares I rocket (the "Stick"), developed by Alliant Techsystems , Rocketdyne , and Boeing . Formerly referred to as the Crew Launch Vehicle (CLV), the Ares I consisted of a single Solid Rocket Booster (SRB) derived in part from the primary boosters used in the Space Shuttle system, connected at its upper end by an interstage support assembly to a new liquid-fueled second stage powered by

436-469: A nuclear thermal rocket stage for each payload, in order to boost them to Mars. Alternatively, chemical (specifically liquid hydrogen/liquid oxygen) propellant stages could have been used, although this would have required more launches. One cargo payload would include a Mars Ascent Vehicle (MAV), as well as In-situ resource utilization equipment to generate propellant for the MAV. The second cargo payload would be

545-727: A statement for the record for various subcommittees of the United States Congress. Most GAO studies and reports are initiated by requests from members of Congress, including requests mandated in statute, and so reflect concerns of current political import, for example to study the impact of a government-wide hiring freeze. Many reports are issued periodically and take a long view of U.S. agencies' operations. The GAO also produces annual reports on key issues such as Duplication and Cost savings and High-Risk Update. The GAO prepares some 900 reports annually. The GAO publishes reports and information relating to, inter alia : Each year

654-649: A "sustainable course of long-term exploration." NASA estimated that the original policy would cost $ 230 billion (in 2004 dollars) through 2025, including the Commercial Crew and Cargo program, which is separate from the Constellation program. However, unsolved technical and design challenges made it impossible for NASA to provide a conclusive estimate. Upon taking office, President Obama declared Constellation to be "over budget, behind schedule, and lacking in innovation." A review concluded that it would cost on

763-482: A June 2019 Government Accountability Office report, NASA concurred that 3D modeling software shall be used "to better integrate components, manage requirement changes, and provide up-to-date designs for all stakeholders". The GAO report stated: "The improved design processes the EGS program is pursuing in the development of the second Mobile Launcher, including the development of a 3D model to facilitate integrated design, have

872-461: A Pacific Ocean splashdown. The Crew Module would then be flown back to Kennedy Space Center for refurbishment, while lunar samples would be routed to the Johnson Space Center 's (JSC) Lunar Receiving Laboratory for analysis. The Orion Asteroid Mission was a proposed NASA mission to a near-Earth asteroid (NEA) which would use the standard Orion spacecraft , and a landing module based on

981-519: A Space Conference on April 15, 2010, in Florida. This came at a time when the president's administration was being criticized considerably for leaving the Constellation Program out of the 2011 budget. At the conference, President Obama and top officials, as well as leaders in the field of spaceflight, discussed the future of U.S. efforts in human spaceflight and unveiled a plan for NASA that followed

1090-667: A complete review, termed the Exploration Systems Architecture Study , which reshaped how NASA would pursue the goals laid out in the Vision for Space Exploration, and its findings were formalized by the NASA Authorization Act of 2005 . The Act directed NASA to "develop a sustained human presence on the Moon, including a robust precursor program to promote exploration, science, commerce and US preeminence in space, and as

1199-523: A countdown simulation of loading the SLS with liquid oxygen and hydrogen — complete with surprise issues the team had to work real-time. July 25, 2019 – A flow test of the Ignition Overpressure Protection and Sound Suppression water deluge system was conducted on the mobile launcher at Launch Pad 39B.

1308-517: A crew module (CM) similar to the Apollo command module , but capable of sustaining four to six crew members; a cylindrical service module (SM) containing the primary propulsion systems and consumable supplies; and the Launch Abort System (LAS), which provides capability for the astronauts and Crew Module to escape from the launch vehicle should problems arise during launch ascent. The Orion Crew Module

1417-496: A habitat that the astronauts would live in during the stay on the surface. In the next launch window, 26 months after the first, the crew would go to Mars in an interplanetary transfer vehicle with nuclear thermal rocket and propellant modules assembled in Earth orbit. Once at Mars, the crew would rendezvous with the Mars habitat in orbit, land on Mars, and explore for 500 days. The crew would use

1526-563: A heavier lift capacity than the Ares I booster provided. In addition to these two boosters, NASA designed other spacecraft for use during Constellation, including the Orion crew capsule, the Earth Departure Stage secondary booster, and the Altair lunar lander. The Orion spacecraft was designed for the Constellation program as a crew compartment for use in low Earth orbit . Lockheed Martin

1635-684: A later flight. Unlike the Apollo CM, which was used only for one flight, an Orion CM could theoretically be used up to ten times under normal operating conditions. Unlike the Apollo missions, where both the Apollo command and service module and the Apollo Lunar Module were launched together on the Saturn V rocket, the crewed Orion spacecraft would be launched separately from the uncrewed EDS and lunar lander. The Ares V/Altair stack would be assembled at

1744-570: A list that encompasses the public, private, and non-profit sectors. The GAO is headed by the comptroller general of the U.S. , a professional and non-partisan position in the U.S. government. The comptroller general is appointed by the president , by and with the advice and consent of the Senate , for a fifteen-year, non-renewable term. The president selects a nominee from a list of at least three individuals recommended by an eight-member bipartisan, bicameral commission of congressional leaders. During such

1853-428: A modified Altair lunar lander. Most of its specific details are now deprecated by the cancellation of the Constellation Program and related designs. Such a mission could assess the potential value of water, iron, nickel, platinum and other resources on the asteroid; test possible ways to extract them; and possibly examine or develop techniques which could be used to protect the Earth from asteroid impacts . This would be

1962-657: A new funding bill for 2011. NASA continues the development of the Orion spacecraft for deep space travel. In an effort to reduce costs, it has contracted for private development of vehicles for use in low Earth orbit. Since May 2020, the Commercial Crew Development program has used the SpaceX Crew Dragon spacecraft to bring people to and from the International Space Station, while Boeing's Starliner spacecraft started operating in 2024 for

2071-547: A process known as Earth orbit rendezvous . NASA planned to use the first vehicles developed in the Constellation Program for Earth-orbit tasks formerly undertaken by the Space Shuttle . But unlike the X-33 and other programs intended to replace the Shuttle, Constellation reused concepts from the Apollo and Space Shuttle programs . The shape of the Orion command module closely resembles

2180-618: A proposal for continued crewed space exploration after the completion of the International Space Station and the planned retirement of the Space Shuttle program in 2010. This proposal was to be a way to "establish an extended human presence on the Moon" to "vastly reduce the costs of further space exploration." Included in this would be the "harvesting and processing of lunar soil into rocket fuel or breathable air." According to Bush, experience gained could help "develop and test new approaches and technologies and systems" to begin

2289-542: A robust research and development program that would include work on propellant depots . After reviewing the report, and following congressional testimony, the Obama administration decided to exclude Constellation from the 2011 United States federal budget . On February 1, 2010, the President's proposed budget was released, which included no funding for the project, and it became law on April 15, 2011. President Obama hosted

2398-465: A speed of 17,500 mph (28,200 km/h) to 300 mph (480 km/h). After reentry was completed, the forward assembly would be jettisoned, and two drogue parachutes released, followed at 20,000 feet (6,100 m) by three main parachutes and airbags filled with nitrogen (N 2 ), which does not combust when exposed to heat, allowing the spacecraft to splashdown. The Command Module would then be returned to Kennedy Space Center for refurbishment for

2507-570: A stepping stone to future exploration of Mars and other destinations." Work began on this revised Constellation Program, to send astronauts first to the International Space Station , then to the Moon , and then to Mars and beyond. Subsequent to the findings of the Augustine Committee in 2009 that the Constellation Program could not be executed without substantial increases in funding, on February 1, 2010, President Barack Obama proposed to cancel

2616-446: A term, the comptroller general has standing to pursue litigation to compel access to federal agency information. The comptroller general may not be removed by the president, but only by Congress through impeachment or joint resolution for specific reasons. Since 1921, there have been only eight comptrollers general, and no formal attempt has ever been made to remove a comptroller general. Labor-management relations became fractious during

2725-473: A variation based on the Orion), and the Ares V cargo-launch vehicle. A design study utilizing Constellation launch vehicles, known as Design Reference Architecture 5.0, was completed in 2009. In DRA 5.0, a Mars mission would have involved multiple launches of an Ares V rocket, as well as an Ares I to launch the crew. In the first Mars launch window , two cargo payloads would be launched into Earth orbit, as well as

2834-541: Is Gene Dodaro , who has served in the position since March 13, 2008. The work of the GAO is done at the request of congressional committees or subcommittees or is mandated by public laws or committee reports.

The program manager of EGS stated in January 2020 that: "The EGS team has finished mobile launcher testing at the launch pad and will finish testing at the VAB in January. At that point, all of the launch infrastructure will be tested and ready for operations." ML-1

3706-458: The Ares V rocket, a rocket based on both Space Shuttle and Apollo technologies. Orion would have been launched separately and would have linked up with Altair in low Earth orbit. Also, unlike Apollo, Orion would have remained uncrewed in lunar orbit while the entire crew landed on the lunar surface. Toward the end of the mission, the Altair spacecraft would have launched into lunar orbit to link up with

3815-597: The European Parliamentary Technology Assessment (EPTA) as an associate member. In 2019, the GAO established a new mission team, the Science, Technology Assessment, and Analytics team, which has primary responsibility for technology assessments. The GAO has published a TA Design Handbook to help technology assessment teams analyze the impact of technology and make complex issues more easily understood and useful to policymakers. The GAO defines TA as

3924-715: The Lunar Orbit Rendezvous method adopted by the Apollo program 's lunar missions with the Earth Orbit Rendezvous method which had also been considered. The name Ares (the Greek god called Mars in Roman mythology) was chosen for the boosters as a reference to the project's goal of landing on Mars. The numbers I and V were chosen to pay homage to the Saturn rockets of the 1960s. The Orion spacecraft would have been launched into

4033-525: The Moon , versus the Saturn V 's 45 metric tons (99,000 lb) lunar payload. The Ares V design consisted of six RS-68 engines with assistance from a pair of 5.5-segment SRBs. Five RS-25 engines were originally planned for the Ares V, but the RS-68 engines are more powerful and less complex and therefore less expensive than the SSMEs. The Ares V would have flown for the first eight minutes of powered flight, then

4142-522: The Saturn V . As of May 2010, the program got as far as launching the first Ares I-X first-stage flight on October 28, 2009 and testing the Orion launch abort system before its cancellation. Ares V would have had a maximum lift capacity of about 188 metric tons (414,000 lb) to low Earth orbit (LEO), compared to the Space Shuttle 's capacity of 24.4 metric tons (54,000 lb), and the Saturn V 's 118 metric tons (260,000 lb). The Ares V would have carried about 71 metric tons (157,000 lb) to

4578-534: The Vehicle Assembly Building and then transported to LC-39A , and the Ares ;M/Orion stack would be transported to the adjacent Pad 39B. The Ares V/EDS/Altair stack would be launched first, into a 220 miles (360 km) high circular orbit. Approximately 90 minutes later, the Ares I/Orion would then launch with the crew into a nearly identical orbit. The Orion would then rendezvous and dock with

4687-481: The Altair to land at a near-polar landing site suitable for a future lunar base. Approaching the lunar far side, the Orion/Altair combination would orient the Altair's engines forward and make the lunar orbit insertion (LOI) burn. Once in lunar orbit, the crew would refine the trajectory and configure the Orion spacecraft for uncrewed flight, allowing all four crew members to transfer to the Altair vehicle and land on

4796-614: The Altair, the crew would perform the Trans Earth Injection (TEI) burn for the return trip to Earth. After a two-and-a-half-day coast, the crew would jettison the Service Module (allowing it to burn up in the atmosphere) and the CM would reenter the Earth's atmosphere using a special reentry trajectory designed to slow the vehicle from its speed of 25,000 miles per hour (40,200 km/h) to 300 miles per hour (480 km/h) and thus allow

4905-608: The Altair/EDS combination already in low-Earth orbit. After the necessary preparations for lunar flight, the EDS would fire for 390 seconds in a translunar injection (TLI) maneuver, accelerating the spacecraft to 25,000 miles per hour (40,200 km/h). After this burn, the EDS would be jettisoned. During the three-day trans-lunar coast, the four-man crew would monitor the Orion's systems, inspect their Altair spacecraft and its support equipment, and correct their flight path as necessary to allow

5014-626: The Augustine Panel's "Flexible Path to Mars" option, modifying President Obama's prior proposal to include the continuing development of the Orion capsule as an auxiliary system to the ISS and setting the year 2015 as the deadline for the design of a new Super Heavy Launch Vehicle. In October 2010, the NASA authorization bill for 2010 was signed into law which canceled Constellation. However, previous legislation kept Constellation contracts in force until passage of

5123-484: The Block II (lunar) Orion CSM and Altair ascent stage would have been adopted. NASA planned to use two separate boosters for the Constellation Program missions – the Ares I for crew and the Ares V for cargo. This would have allowed the two launch vehicles to be optimized for their respective missions, and allowed a much higher total lift for the Ares V without being cost-prohibitive. The Constellation Program thus combined

5232-516: The Earth Departure Stage would have placed itself and the Altair spacecraft into low Earth orbit while awaiting the arrival of the Orion. Toward the end of the program, it became apparent that the ablatively-cooled RS-68B engines would not withstand the heat from the solid rocket boosters at launch, and NASA began again to consider using RS-25 engines instead of upgrading the RS-68 to be regeneratively-cooled . The Earth Departure Stage (EDS)

5341-823: The GAO analysts bargaining unit; the local voted to name itself IFPTE Local 1921, in honor of the date of the GAO's establishment. On February 14, 2008, the GAO analysts' union approved its first-ever negotiated pay contract with management; of just over 1,200 votes, 98% were in favor of the contract. The GAO also establishes standards for audits of government organizations, programs, activities, and functions, and of government assistance received by contractors, nonprofit organizations, and other nongovernmental organizations. These standards, often referred to as Generally Accepted Government Auditing Standards (GAGAS), are to be followed by auditors and audit organizations when required by law, regulation, agreement, contract, or policy. These standards pertain to auditors' professional qualifications,

5450-580: The GAO issues an audit report on the financial statements of the United States Government. The 2010 Financial Report of the United States Government was released on December 21, 2010. The accompanying press release states that the GAO 'cannot render an opinion on the 2010 consolidated financial statements of the federal government , because of widespread material internal control weaknesses, significant uncertainties, and other limitations'. As part of its initiative to advocate sustainability ,

5559-533: The GAO publishes a Federal Fiscal Outlook Report, as well as data relating to the deficit . The U.S. deficit is presented on a cash rather than accruals basis, although the GAO notes that the accrual deficit "provides more information on the longer-term implications of the government's annual operations". In FY 2010, the US federal government had a net operating cost of $ 2,080 billion, although since this includes accounting provisions (estimates of future liabilities),

5668-652: The GAO's current mission statement, the agency exists to support the Congress in meeting its constitutional responsibilities and to help improve the performance and ensure the accountability of the federal government for the benefit of the American people. The name was changed in 2004 to the Government Accountability Office by the GAO Human Capital Reform Act to better reflect the mission of

5777-651: The IRS, the Centers for Medicare and Medicaid Services, the Department of Veterans Affairs, and the Department of Homeland Security, among others. Unsuccessful bidders for government contracts may submit protests if they have reason to challenge an agency's decision, and the GAO may then release a report on the decision, redacted if necessary. Various GAO decisions have confirmed that: In reviewing protests of an agency’s evaluation, [GAO] does not reevaluate proposals, rather, we review

5886-490: The J-2X, NASA engineers visited museums, searched for Apollo-era documentation and consulted with engineers who worked on the Apollo program. "The mechanics of landing on the Moon and getting off the Moon to a large extent have been solved," said Constellation program manager Jeff Hanley. "That is the legacy that Apollo gave us." However, as the J-2X program progressed, it became apparent that, because of revised safety requirements and

5995-597: The Lunar Module, was not designed to be reusable, and the ascent stage would be discarded after use. The Altair descent stage was to be powered by four RL-10 rocket engines, which are also those used in the Centaur upper stage of the Atlas V rocket. Unlike the current RL-10 engines in use, these newer RL-10s were to have the ability to throttle down to as low as 10% rated thrust (the older specifications allow for 20%), thus allowing

6104-412: The MAV to return to their interplanetary vehicle in Mars orbit, which would then be used to return to Earth. The mission would conclude with the re-entry and landing of the Orion capsule. NASA lists a number of reasons for a human return to the Moon on its website: In the words of former NASA Administrator, Michael D. Griffin , "The goal isn't just scientific exploration.... It's also about extending

6213-474: The Moon, while the Orion waits for their return. Upon receiving clearance from Mission Control, the Altair would undock from the Orion and perform an inspection maneuver, allowing ground controllers to inspect the spacecraft via live TV mounted on Orion for any visible problems that would prevent landing (on Apollo this was done by the Command Module Pilot). After receiving approval from ground controllers,

The design of the launch vehicle taking Orion into orbit, the Ares I , employs many concepts from the Apollo program. The design of the J-2X engine intended for use on the Ares V booster rocket was originally to be similar to the J-2 engine of the Apollo-era Saturn V and Saturn IB rockets. In designing

6867-694: The agency in "taking corrective action in the face of a clearly meritorious protest". The GAO confirmed in 2014 that its jurisdiction includes investigation of protests raising allegations of agency violation of the Procurement Integrity Act . After the closing of the Office of Technology Assessment (OTA) in 1995, Congress directed the GAO to conduct a technology assessment (TA) pilot program. Between 2002 and 2005, three reports were completed–-use of biometrics for border security, cyber security for critical infrastructure protection , and technologies for protecting structures in wildland fires. The GAO reports and technology assessments, which are made available to

6976-456: The agency's current course invited "failure, disillusionment, and [loss of] the longstanding international perception that human space-flight is something that the United States does best." The report recommended that Mars be the next major goal of human space flight. Several possible paths for reaching the planet by 2037 were explored in the report, which noted that returning to the Moon would offer "significant advantages" as an intermediate step in

The most recent GAO strategic plan, for 2018–2023, sets out four goals, namely: The Forensic Audits and Investigative Service (FAIS) team provides Congress with high-quality forensic audits and investigations of fraud, waste, and abuse; other special investigations; and security and vulnerability assessments. Its work cuts across a diverse array of government programs administered by

7194-405: The crew would then enter the Altair and fire the ascent stage engine to lift off from the surface, using the descent stage as a launchpad (and leaving it as a platform for future base construction). Upon entering orbit, the Altair would rendezvous and dock with the waiting Orion spacecraft, and the crew would then transfer, along with samples collected on the Moon, back to the Orion. After jettisoning

7303-408: The crew would then reenter the Orion, seal itself off from the ISS, and then undock from the station. Once the Orion reached a safe distance from the ISS, the Command Module (after having jettisoned the disposable service module) would re-enter in the same manner as all NASA spacecraft prior to the Shuttle, using the ablative heat shield to both deflect heat from the spacecraft and to slow it down from

7412-435: The design of its new Space Launch System . One of the main goals of Constellation was the development of spacecraft and booster vehicles to replace the Space Shuttle . NASA had already begun designing two boosters, the Ares I and Ares V , when the program was created. Ares I was designed for the sole purpose of launching mission crews into orbit, while Ares V would have been used to launch other hardware which required

There is a facility within the Bid Protest Regulations for the GAO to recommend reimbursement of a bidder's protest costs if the procuring agency takes corrective action in response to a protest. The circumstances justifying bid protest cost reimbursement must involve "undue delay" by

7739-482: The even larger SLS Block 1B was undesirable, as it would induce a 33-month delay between SLS launches to undertake the needed modifications. Congress funded $ 350M in 2018 for construction of ML-2, and in 2019 NASA awarded a $ 383M 44-month contract, with completion scheduled for March 2023. ML-2 is expected to run into fewer challenges than ML-1, the Inspector General report states, as NASA is "taking steps to incorporate lessons learned" from ML-1. For example, as suggested by

Like Apollo, Constellation would have flown a lunar orbit rendezvous mission profile, but unlike Apollo, Constellation would have also employed Earth orbit rendezvous , conveying the crew to the vehicle. The lander, known as Altair , would have been launched separately on

8393-462: The initial stack during takeoff, would meet with the International Space Station . After getting the go ahead from Houston, Orion would then dock with the ISS. The six-man crew (at a maximum) would then enter the station in order to perform numerous tasks and activities for the duration of their flight, usually lasting six months, but possibly shortened to four or lengthened to eight, depending upon NASA's goals for that particular mission. Once completed,

8502-435: The landing gear. Like its predecessor, the Altair design consists of two parts: an ascent stage which houses the four-person crew; and a descent stage consisting of the landing gear, and storage for the majority of the crew's consumables (oxygen and water) and for scientific equipment. Unlike the Lunar Module, Altair was designed to land in the lunar polar regions favored by NASA for future lunar base construction. Altair, like

8611-549: The landing module in a manner similar to that of Apollo 13 before entering the atmosphere for a Pacific Ocean splashdown. The ultimate goal of NASA's Constellation program was a crewed mission landing humans on Mars in the 2030s as a spiritual successor to the Apollo Applications Program in the 1960s. The mission would utilize the hardware of the Constellation Project, primarily the Orion spacecraft (or

On September 19, 2007, GAO analysts voted by a margin of two to one (897–445), in a 75% turnout, to establish the first union in the GAO's 86-year history. The analysts voted to affiliate with the International Federation of Professional and Technical Engineers (IFPTE), a member union of the AFL–CIO . There are more than 1,800 analysts in

8938-423: The office. The GAO's auditors conduct not only financial audits, but also engage in a wide assortment of performance audits. Over the years, the GAO has been referred to as "The Congressional Watchdog" and "The Taxpayers' Best Friend" for its frequent audits and investigative reports that have uncovered waste and inefficiency in government. News media often draw attention to the GAO's work by publishing stories on

9047-444: The order of $ 150 billion for Constellation to reach its objective if adhering to the original schedule. Another review in 2009, ordered by President Obama, indicated that neither a return to the Moon nor a crewed flight to Mars was within NASA's current budget. The Augustine panel proposed various options, that included two primary destination points (the Moon and deep space), three different types of Super Heavy Launch vehicles , and

9156-551: The polar regions of the Moon. There were no well-defined plans at the time of cancelation for a crewed flight to Mars , the ultimate goal of the project, but a mission to a Near-Earth asteroid was in the initial planning phase as of 2008. After being manufactured at private plants, the parts of the Ares I/Orion stack would be tested and assembled at the Vehicle Assembly Building at the Kennedy Space Center . Once assembly

9483-406: The primary activities of EGS has been to prepare all infrastructure needed to launch SLS. SLS will use a mobile launcher platform , which is a launch structure that moves out with the rocket to the launch pad ( LC-39B ), carried atop a Crawler Transporter . Under the Constellation program , a new platform was constructed, called Mobile Launcher-1 (ML-1), for the Ares I . This initial construction

9592-479: The process. The National Space Society (NSS), a private nonprofit, regards a return to the Moon as a high priority for the US space program, in order to develop the body of scientific knowledge of the Moon, particularly in regards to its potential for the creation of new industries, in order to provide further funding for further space exploration. On January 14, 2004 President George W. Bush requested that NASA develop

9701-587: The program's booster rockets: Ares (the Greek equivalent of the Roman god Mars ). The technological aims of the program included the regaining of significant astronaut experience beyond low Earth orbit and the development of technologies necessary to enable sustained human presence on other planetary bodies. Constellation began in response to the goals laid out in the Vision for Space Exploration under NASA Administrator Sean O'Keefe and President George W. Bush . O'Keefe's successor, Michael D. Griffin , ordered

9810-423: The program, effective with the passage of the U.S. 2011 fiscal year budget . He then revised administration statements in a major space policy speech at Kennedy Space Center on April 15, 2010. On October 11, the signing of the NASA Authorization Act of 2010 shelved the program, with Constellation contracts remaining in place until Congress would act to overturn the previous mandate. In 2011, NASA adopted

9919-401: The public, have become essential vehicles for understanding science and technology (S&T) implications of policies considered by the Congress. Since 2008, Congress has established a permanent TA function within the GAO. This new operational role augments GAO's performance audits related to S&T issues, including effectiveness and efficiency of U.S. federal programs. In 2010, the GAO joined

10028-544: The quality of audit effort, and the characteristics of professional and meaningful audit reports. In 1992, the GAO hosted the XIV INCOSAI , the fourteenth triennial convention of the International Organization of Supreme Audit Institutions (INTOSAI). The GAO is a United States government electronic data provider, as all of its reports are available on its website, except for certain reports whose distribution

10137-689: The range of human habitat out from Earth into the Solar System as we go forward in time.... In the long run a single-planet species will not survive.... If we humans want to survive for hundreds of thousands or millions of years, we must ultimately populate other planets ... colonize the Solar System and one day go beyond." A report published in June 2014 by the US National Academy of Sciences called for clear long-term space goals at NASA. The report said that

10246-546: The same purpose. Furthermore, it seeks human-rating for the launch vehicles in the United States Air Force's Evolved Expendable Launch Vehicles program. Private spacecraft are also operating under the Commercial Resupply Services program bringing cargo to ISS. The Orion spacecraft and Ares V (also Jupiter DIRECT family of rockets) was modified and reauthorized in 2010/2011 as the main payload of

10355-517: The second stage with liquid hydrogen (LH 2 ) and liquid oxygen (LOX) fuel, and the crew, wearing all-purpose spacesuits , would enter the spacecraft three hours before liftoff. Once they were locked in, and after all systems were cleared by controllers at both the Cape and Mission Control in Houston, the Ares I would then launch. After a two-day orbital chase, the Orion spacecraft , having jettisoned much of

10464-463: The system. May 6, 2020 – Launch Pad 39B at NASA's Kennedy Space Center in Florida is the site of NASA's return to the Moon and is now ready for Artemis 1 —an uncrewed mission around the Moon and back. Exploration Ground Systems (EGS) has completed modifications and upgrades to the launch pad for the Space Launch System (SLS) rocket and Orion spacecraft to help accomplish NASA's lunar exploration goals. April 27, 2021 – The last component of Artemis 1 ,

10573-427: The two craft would separate to a safe distance and the Altair's descent engines would fire again for powered descent to a pre-determined landing spot previously selected by uncrewed spacecraft. Upon landing, the crew would put on their extravehicular activity (EVA) spacesuits and commence the first of five to seven lunar EVAs, collecting samples and deploying experiments. After completing their Lunar Sortie operations,

10682-509: The use of Altair for both the lunar orbit insertion (LOI) and landing stages of lunar missions. The ascent stage was designed to be powered by a single engine, likely a hypergolic engine similar or identical to the main engine of the Orion CSM, which would use the descent stage as both a launchpad and a platform for future base construction. Alternately, there was a small possibility that the original plan of using LOX/CH 4 –fueled engines on board

10791-401: The world’s most powerful rocket sent an uncrewed Orion spacecraft to lunar orbit and back in preparation for sending humans to live and work on the Moon.

10900-524: Was completed and a launch date was set, the crawler-transporter would transport the completed stack, along with the launch support tower and the Mobile Launcher-1 , out to LC-39B . Once the crawler-transporter reached the pad, the stack and the Launcher Platform would be left in place and the crawler-transporter removed to a safe distance. After final safety checks, the ground crew would fill up

11009-601: Was completed in August 2010, at a cost of $ 234 million. After the cancellation of Constellation and the beginning of SLS, NASA decided to modify ML-1 for SLS. In August 2011, it was estimated that modifying ML-1 would cost $ 54M, modifying the old Space Shuttle launch platform would cost $ 93M, and building a brand new platform would cost $ 122M. However, in March 2020, a report from the NASA Inspector General came out, stating that ML-1

11118-523: Was completed on the Orion Service Module Umbilical (OSMU) on the MLP. The test verified umbilical arm alignment, rotation speed, and latch back systems. The OSMU will transfer power, data, and coolant for the electronics, and purge air for the environmental controls to the Orion service module and Launch Abort System. October 30 – November 6, 2018 – Underway Recovery Test-7 (URT-7) was conducted in

11227-478: Was costing millions per year. In 2013, NASA signed a long-term lease of LC-39A to SpaceX . Blue Origin filed a protest to the Government Accountability Office that the pad should not be made exclusive, and should be operated by a tenant that would sublease to multiple different users and rockets to take advantage of. However, the GAO rejected this petition and allowed the lease to SpaceX, as there

11336-405: Was designed to be the main transport vehicle for astronauts on lunar missions. The Altair design was much larger than its predecessor, the Apollo Lunar Module , at almost five times the volume, occupying a total of 1,120 cubic feet (32 m ) compared with the Apollo lander's 235 cubic feet (6.7 m ). It was to stand 32 feet (9.8 m) tall and span 49 feet (15 m) wide from tip to tip of

11445-557: Was established as the General Accounting Office by the Budget and Accounting Act of 1921. The act required the head of the GAO to: investigate, at the seat of government or elsewhere, all matters relating to the receipt, disbursement, and application of public funds, and shall make to the President ... and to Congress ... reports [and] recommendations looking to greater economy or efficiency in public expenditures. According to

11554-563: Was intended to support multiple users. However, as time went on, the alternate launch vehicles that were to use LC-39B were all eventually removed from the plan or canceled entirely, such as Liberty and OmegA . OmegA was the final removal, with its cancellation and planned demolition of its launch tower in September 2020. This leaves EGS solely focused on supporting the Space Launch System and Orion spacecraft , meaning LC-39B will enjoy at most one launch per year under current launch manifests. In

11663-546: Was no stated preference by NASA for or against a multiuser approach. EGS was intended in general to "support several different kinds of spacecraft and rockets that are in development ... unlike previous work focusing on a single kind of launch vehicle, such as the Saturn V or Space Shuttle ... EGS's mission is to transform the center from a historically government-only launch complex to a spaceport that can handle several different kinds of spacecraft and rockets—both government and commercial.". The other LC-39 pad, LC-39B, specifically

11772-486: Was selected as the prime contractor for the Orion project on August 31, 2006, and Boeing was selected to build its primary heat shield on September 15, 2006. NASA initially planned to develop different Orion capsules tailored for specific missions. The Block I Orion was to be used for International Space Station missions and other Earth orbit missions, while the Block II and III variants were designed for deep-space exploration. Orion's design consists of three main parts:

11881-479: Was the propulsion system designed to put the Altair upper stage on a lunar trajectory from within low Earth orbit. It was designed as the second liquid-fueled stage of the Ares V rocket. The Orion spacecraft would have been launched separately by Ares I, and then met and docked with the Ares V-launched EDS/Altair combination, delivering the crew and configuring the spacecraft for its journey to the Moon in
