Its director was Michael Freilich (2006–2019). NASA supports research in
256-478: A federal structure with two overlapping power centers so that each citizen as an individual is subject to the powers of state government and national government. To protect against abuse of power, each branch of government – executive, legislative, and judicial – had a separate sphere of authority and could check other branches according to the principle of the separation of powers . Furthermore, there were checks and balances within
384-582: A "driving force in American government" and a "remarkably resilient institution". Congress is the "heart and soul of our democracy", according to this view, even though legislators rarely achieve the prestige or name recognition of presidents or Supreme Court justices ; one wrote that "legislators remain ghosts in America's historical imagination." One analyst argues that it is not a solely reactive institution but has played an active role in shaping government policy and
512-468: A Senate and House of Representatives." The House and Senate are equal partners in the legislative process – legislation cannot be enacted without the consent of both chambers. The Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue -raising bills. The House initiates impeachment cases, while
640-607: A decade of reliance on the Russians. In 2019, NASA announced the Artemis program , intending to return to the Moon and establish a permanent human presence. This was paired with the Artemis Accords with partner nations to establish rules of behavior and norms of space commercialization on the Moon. In 2023, NASA established the Moon to Mars Program office. The office is designed to oversee
768-629: A month after the Soviet Yuri Gagarin became the first human in space, executing a full orbital spaceflight. NASA's first orbital spaceflight was conducted by John Glenn on February 20, 1962, in the Friendship 7 , making three full orbits before reentering. Glenn had to fly parts of his final two orbits manually due to an autopilot malfunction. The sixth and final Mercury mission was flown by Gordon Cooper in May 1963, performing 22 orbits over 34 hours in
896-570: A permanently manned space station and to do it within a decade. In 1985, NASA proposed the Space Station Freedom , which both the agency and President Reagan intended to be an international program. While this would add legitimacy to the program, there were concerns within NASA that the international component would dilute its authority within the project, having never been willing to work with domestic or international partners as true equals. There
1024-628: A possible source of antimatter at the center of the Milky Way and observing that the majority of gamma-ray bursts occur outside of the Milky Way galaxy. The Chandra X-ray Observatory was launched from the Columbia on STS-93 in 1999, observing black holes, quasars , supernova , and dark matter . It provided critical observations on the Sagittarius A* black hole at the center of the Milky Way galaxy and
1152-444: A powerful effect of waking up a somewhat dormant Congress which investigated presidential wrongdoing and coverups; the scandal "substantially reshaped" relations between the branches of government, suggested political scientist Bruce J. Schulman . Partisanship returned, particularly after 1994; one analyst attributes partisan infighting to slim congressional majorities which discouraged friendly social gatherings in meeting rooms such as
1280-514: A revised constitution with a two-chamber or bicameral Congress. Smaller states argued for equal representation for each state. The two-chamber structure had functioned well in state governments. A compromise plan, the Connecticut Compromise , was adopted with representatives chosen by population (benefiting larger states) and exactly two senators chosen by state governments (benefiting smaller states). The ratified constitution created
1408-532: A space station since the agency was created. In 1973, following the end of the Apollo lunar missions, NASA launched its first space station, Skylab , on the final launch of the Saturn V. Skylab reused a significant amount of Apollo and Saturn hardware, with a repurposed Saturn V third stage serving as the primary module for the space station. Damage to Skylab during its launch required spacewalks to be performed by

#17330853308331536-566: A state's at-large representation to the federal government by senators. Most incumbents seek re-election, and their historical likelihood of winning subsequent elections exceeds 90 percent. The historical records of the House of Representatives and the Senate are maintained by the Center for Legislative Archives, which is a part of the National Archives and Records Administration . Congress
1664-595: A tie. The House of Representatives has six non-voting members . Congress convenes for a two-year term , commencing every other January. Elections are held every even-numbered year on Election Day . The members of the House of Representatives are elected for the two-year term of a Congress. The Reapportionment Act of 1929 established that there be 435 representatives, and the Uniform Congressional Redistricting Act requires that they be elected from single-member constituencies or districts . It
1792-497: Is also required that the congressional districts be apportioned among states by population every ten years using the U.S. census results, provided that each state has at least one congressional representative. Each senator is elected at-large in their state for a six-year term, with terms staggered , so every two years approximately one-third of the Senate is up for election. Each state, regardless of population or size, has two senators, so currently, there are 100 senators for
1920-551: Is an independent agency of the U.S. federal government responsible for the civil space program , aeronautics research, and space research. Established in 1958 , it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science . It has since led most of America's space exploration programs, including Project Mercury , Project Gemini ,
2048-663: Is directly responsible for the governing of the District of Columbia , the current seat of the federal government. The First Continental Congress was a gathering of representatives from twelve of the Thirteen Colonies . On July 4, 1776, the Second Continental Congress adopted the Declaration of Independence , referring to the new nation as the "United States of America". The Articles of Confederation in 1781 created
2176-440: Is elected and gives each House the power to create its own structure. Section Seven lays out the process for creating laws, and Section Eight enumerates numerous powers. Section Nine is a list of powers Congress does not have, and Section Ten enumerates powers of the state, some of which may only be granted by Congress. Constitutional amendments have granted Congress additional powers. Congress also has implied powers derived from
2304-486: Is essentially charged with reconciling our many points of view on the great public policy issues of the day. Congress is constantly changing and is constantly in flux. In recent times, the American South and West have gained House seats according to demographic changes recorded by the census and includes more women and minorities . While power balances among the different parts of government continue to change,
2432-433: Is extraordinarily sensitive to public pressure. Several academics described Congress: Congress reflects us in all our strengths and all our weaknesses. It reflects our regional idiosyncrasies, our ethnic, religious, and racial diversity, our multitude of professions, and our shadings of opinion on everything from the value of war to the war over values. Congress is the government's most representative body ... Congress
2560-583: The Faith 7 . The Mercury Program was wildly recognized as a resounding success, achieving its objectives to orbit a human in space, develop tracking and control systems, and identify other issues associated with human spaceflight. While much of NASA's attention turned to space, it did not put aside its aeronautics mission. Early aeronautics research attempted to build upon the X-1's supersonic flight to build an aircraft capable of hypersonic flight . The North American X-15
2688-529: The tabloidization of media coverage. Others saw pressure to squeeze a political position into a thirty-second soundbite. A report characterized Congress in 2013 as unproductive, gridlocked, and "setting records for futility". In October 2013, with Congress unable to compromise, the government was shut down for several weeks and risked a serious default on debt payments, causing 60% of the public to say they would "fire every member of Congress" including their own representative. One report suggested Congress posed

The Soviet Union's launch of Sputnik 1 ushered in the Space Age and kicked off the Space Race . Despite NACA's early rocketry program, the responsibility for launching the first American satellite fell to the Naval Research Laboratory 's Project Vanguard , whose operational issues ensured
3072-658: The Big Bang . The James Webb Space Telescope , named after the NASA administrator who lead the Apollo program, is an infrared observatory launched in 2021. The James Webb Space Telescope is a direct successor to the Hubble Space Telescope, intended to observe the formation of the first galaxies. Other space telescopes include the Kepler space telescope , launched in 2009 to identify planets orbiting extrasolar stars that may be Terran and possibly harbor life. The first exoplanet that
3200-540: The Board of Education . Congress began reasserting its authority. Lobbying became a big factor despite the 1971 Federal Election Campaign Act . Political action committees or PACs could make substantive donations to congressional candidates via such means as soft money contributions. While soft money funds were not given to specific campaigns for candidates, the money often benefited candidates substantially in an indirect way and helped reelect candidates. Reforms such as
3328-527: The Commerce Clause , the enumerated power to regulate commerce, in rulings such as McCulloch v. Maryland , have effectively widened the scope of Congress's legislative authority far beyond that prescribed in Section Eight. Constitutional responsibility for the oversight of Washington, D.C. , the federal district and national capital, and the U.S. territories of Guam , American Samoa , Puerto Rico ,
3456-569: The Congress of the Confederation , a unicameral body with equal representation among the states in which each state had a veto over most decisions. Congress had executive but not legislative authority, and the federal judiciary was confined to admiralty and lacked authority to collect taxes, regulate commerce, or enforce laws. Government powerlessness led to the Convention of 1787 which proposed
3584-599: The Conservative Coalition . Democrats maintained control of Congress during World War II . Congress struggled with efficiency in the postwar era partly by reducing the number of standing congressional committees. Southern Democrats became a powerful force in many influential committees although political power alternated between Republicans and Democrats during these years. More complex issues required greater specialization and expertise, such as space flight and atomic energy policy. Senator Joseph McCarthy exploited
3712-660: The Earth Observing System ; advancing heliophysics through the efforts of the Science Mission Directorate 's Heliophysics Research Program; exploring bodies throughout the Solar System with advanced robotic spacecraft such as New Horizons and planetary rovers such as Perseverance ; and researching astrophysics topics, such as the Big Bang , through the James Webb Space Telescope ,

Launched in the 1990s and early 2000s, the Great Observatories program are among NASA's most powerful telescopes. The Hubble Space Telescope
4736-631: The STS-1 mission, designed to serve as a flight test for the new spaceplane. NASA intended for the Space Shuttle to replace expendable launch systems like the Air Force's Atlas , Delta , and Titan and the European Space Agency 's Ariane . The Space Shuttle's Spacelab payload, developed by the European Space Agency, increased the scientific capabilities of shuttle missions over anything NASA
4864-616: The STS-60 mission in 1994 and the Discovery rendezvoused, but did not dock with, the Russian Mir in the STS-63 mission. This was followed by Atlantis' STS-71 mission where it accomplished the initial intended mission for the Space Shuttle, docking with a space station and transferring supplies and personnel. The Shuttle- Mir program would continue until 1998, when a series of orbital accidents on
4992-471: The Space Race when the Soviet Union gave up its lunar ambitions. As the first human to step on the surface of the Moon, Neil Armstrong uttered the now famous words: That's one small step for man, one giant leap for mankind. NASA would conduct six total lunar landings as part of the Apollo program, with Apollo 17 concluding the program in 1972. Wernher von Braun had advocated for NASA to develop
5120-609: The Space Shuttle began in 1972, with Rockwell International contracted to design the orbiter and engines, Martin Marietta for the external fuel tank , and Morton Thiokol for the solid rocket boosters . NASA acquired six orbiters: the Enterprise , Columbia , Challenger , Discovery , Atlantis , and Endeavour The Space Shuttle program also allowed NASA to make major changes to its Astronaut Corps .

Despite these successes, Congress was unwilling to fund further interplanetary missions and NASA Administrator James Webb suspended all future interplanetary probes to focus resources on the Apollo program. Following the conclusion of the Apollo program, NASA resumed launching interplanetary probes and expanded its space science program. The first planet tagged for exploration
5632-445: The second-wave feminism movement , when activists moved into electoral politics. Beginning in the 1970s, donors and political action committees like EMILY's List began recruiting, training and funding women candidates. Watershed political moments like the confirmation of Clarence Thomas and the 2016 presidential election created momentum for women candidates, resulting in the Year of
5760-479: The "biggest risk to the U.S. economy" because of its brinksmanship , "down-to-the-wire budget and debt crises" and "indiscriminate spending cuts", resulting in slowed economic activity and keeping up to two million people unemployed. There has been increasing public dissatisfaction with Congress, with extremely low approval ratings which dropped to 5% in October 2013. In 2009, Congress authorized another delegate for
5888-439: The 1960s opened the possibility for Black, Asian American, Latina and other non-white women candidates to run for Congress. Racially polarized voting, racial stereotypes and lack of institutional support still prevent women of color from reaching Congress as easily as white people . Senate elections, which require victories in statewide electorates, have been particularly difficult for women of color. Carol Moseley Braun became
6016-516: The 1960s, blending the administration's dual aeronautics and space missions. NASA viewed a spaceplane as part of a larger program, providing routine and economical logistical support to a space station in Earth orbit that would be used as a hub for lunar and Mars missions. A reusable launch vehicle would then have ended the need for expensive and expendable boosters like the Saturn V . In 1969, NASA designated
6144-690: The 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle . Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program , and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program . NASA's science division is focused on better understanding Earth through
6272-790: The 2002 Bipartisan Campaign Reform Act limited campaign donations but did not limit soft money contributions. One source suggests post-Watergate laws amended in 1974 meant to reduce the "influence of wealthy contributors and end payoffs" instead "legitimized PACs" since they "enabled individuals to band together in support of candidates". From 1974 to 1984, PACs grew from 608 to 3,803 and donations leaped from $ 12.5 million to $ 120 million along with concern over PAC influence in Congress. In 2009, there were 4,600 business, labor and special-interest PACs including ones for lawyers , electricians , and real estate brokers . From 2007 to 2008, 175 members of Congress received "half or more of their campaign cash" from PACs. From 1970 to 2009,

#17330853308336656-450: The Air Force as the military space lead. Plans for human spaceflight began in the U.S. Armed Forces prior to NASA's creation. The Air Force's Man in Space Soonest project formed in 1956, coupled with the Army's Project Adam, served as the foundation for Project Mercury . NASA established the Space Task Group to manage the program, which would conduct crewed sub-orbital flights with the Army's Redstone rockets and orbital flights with
6784-448: The Air Force's Atlas launch vehicles. While NASA intended for its first astronauts to be civilians, President Eisenhower directed that they be selected from the military. The Mercury 7 astronauts included three Air Force pilots, three Navy aviators, and one Marine Corps pilot. On May 5, 1961, Alan Shepard became the first American to enter space, performing a suborbital spaceflight in the Freedom 7 . This flight occurred less than
6912-457: The American response as a "police action". According to Time magazine in 1970, "U.S. presidents [had] ordered troops into position or action without a formal congressional declaration a total of 149 times." In 1993, Michael Kinsley wrote that "Congress's war power has become the most flagrantly disregarded provision in the Constitution," and that the "real erosion [of Congress's war power] began after World War II." Disagreement about

Despite attacks on the goal of landing astronauts on the Moon from the former president Dwight Eisenhower and 1964 presidential candidate Barry Goldwater , President Kennedy was able to protect NASA's growing budget, of which 50% went directly to human spaceflight and it was later estimated that, at its height, 5% of Americans worked on some aspect of the Apollo program. Mirroring
7168-478: The Army Ballistic Missile Agency's original Saturn I . The Apollo spacecraft was designed and built by North American Aviation , while the Apollo Lunar Module was designed and built by Grumman . To develop the spaceflight skills and equipment required for a lunar mission, NASA initiated Project Gemini . Using a modified Air Force Titan II launch vehicle, the Gemini capsule could hold two astronauts for flights of over two weeks. Gemini pioneered
7296-401: The Congress has started and ended at noon on the third day of January of every odd-numbered year. Members of the Senate are referred to as senators; members of the House of Representatives are referred to as representatives, congressmen, or congresswomen. Scholar and representative Lee H. Hamilton asserted that the "historic mission of Congress has been to maintain freedom" and insisted it was

Development of the Saturn V rocket was led by Wernher von Braun and his team at the Marshall Space Flight Center , derived from
7680-493: The Government of the United States, or in any Department or Officer thereof". Article Four gives Congress the power to admit new states into the Union. One of Congress's foremost non-legislative functions is the power to investigate and oversee the executive branch. Congressional oversight is usually delegated to committees and is facilitated by Congress's subpoena power. Some critics have charged that Congress has in some instances failed to do an adequate job of overseeing
7808-435: The House expanded delegates, along with their powers and privileges representing U.S. citizens in non-state areas, beginning with representation on committees for Puerto Rico's resident commissioner in 1970. In 1971, a delegate for the District of Columbia was authorized, and in 1972 new delegate positions were established for U.S. Virgin Islands and Guam . In 1978, an additional delegate for American Samoa were added. In

NASA also launched missions to Mercury in 2004, with the MESSENGER probe demonstrating as the first use of a solar sail . NASA also launched probes to the outer Solar System starting in the 1960s. Pioneer 10 was the first probe to the outer planets, flying by Jupiter , while Pioneer 11 provided
8448-402: The Moon and going to Mars. Embracing this approach, NASA's Commercial Crew Program started by contracting cargo delivery to the International Space Station and flew its first operational contracted mission on SpaceX Crew-1 . This marked the first time since the retirement of the Space Shuttle that NASA was able to launch its own astronauts on an American spacecraft from the United States, ending

No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. Kennedy gave his " We choose to go to the Moon " speech the next year, on September 12, 1962 at Rice University , where he addressed the nation hoping to reinforce public support for
8832-409: The Russians be included. In 1993, the Clinton Administration announced that the Space Station Freedom would become the International Space Station in an agreement with the Russian Federation. This allowed the Russians to maintain their space program through an infusion of American currency to maintain their status as one of the two premier space programs. While the United States built and launched
8960-507: The Russians to fly to the International Space Station for four days, despite the opposition of NASA to the idea. Advocates of this new commercial approach for NASA included former astronaut Buzz Aldrin , who remarked that it would return NASA to its roots as a research and development agency, with commercial entities actually operating the space systems. Having corporations take over orbital operations would also allow NASA to focus all its efforts on deep space exploration and returning humans to
9088-431: The Senate decides impeachment cases. A two-thirds vote of the Senate is required before an impeached person can be removed from office. The term Congress can also refer to a particular meeting of the legislature. A Congress covers two years; the current one, the 118th Congress , began on January 3, 2023, and will end on January 3, 2025. Since the adoption of the Twentieth Amendment to the United States Constitution ,

Mariner 5 was the first NASA spacecraft to flyby Mars, followed by Mariner 6 and Mariner 7 . Mariner 9 was the first orbital mission to Mars. Launched in 1975, Viking program consisted of two landings on Mars in 1976. Follow-on missions would not be launched until 1996, with
9344-602: The Space Shuttle Columbia disaster in 2003, NASA was forced to rely on Russian Soyuz launches for its astronauts and the 2011 retirement of the Space Shuttle accelerated the station's completion. In the 1980s, right after the first flight of the Space Shuttle, NASA started a joint program with the Department of Defense to develop the Rockwell X-30 National Aerospace Plane. NASA realized that
9472-418: The Space Shuttle allowed NASA to begin recruiting more non-military scientific and technical experts. A prime example is Sally Ride , who became the first American woman to fly in space on STS-7 . This new astronaut selection process also allowed NASA to accept exchange astronauts from U.S. allies and partners for the first time. The first Space Shuttle flight occurred in 1981, when the Columbia launched on
9600-505: The Space Shuttle and expand space exploration beyond low Earth orbit. Constellation was intended to use a significant amount of former Space Shuttle equipment and return astronauts to the Moon. This program was canceled by the Obama Administration . Former astronauts Neil Armstrong , Gene Cernan , and Jim Lovell sent a letter to President Barack Obama to warn him that if the United States did not get new human spaceflight ability,
9728-544: The Space Shuttle began flying, selling it as an orbital laboratory, repair station, and a jumping off point for lunar and Mars missions. NASA found a strong advocate in President Ronald Reagan , who declared in a 1984 speech: America has always been greatest when we dared to be great. We can reach for greatness again. We can follow our dreams to distant stars, living and working in space for peaceful, economic, and scientific gain. Tonight I am directing NASA to develop
9856-660: The Space Shuttle, while a massive technological accomplishment, would not be able to live up to all its promises. Designed to be a single-stage-to-orbit spaceplane, the X-30 had both civil and military applications. With the end of the Cold War , the X-30 was canceled in 1992 before reaching flight status. Following the Space Shuttle Columbia disaster in 2003, President Bush started the Constellation program to smoothly replace
9984-483: The Space Shuttle. Due to technical challenges, the spacecraft was cancelled in 2001. Despite this, it was the first time a commercial space company directly expended a significant amount of its resources into spacecraft development. The advent of space tourism also forced NASA to challenge its assumption that only governments would have people in space. The first space tourist was Dennis Tito , an American investment manager and former aerospace engineer who contracted with
10112-571: The Space Station Freedom was controversial, with much of the debate centering on cost. Several redesigns to reduce cost were conducted in the early 1990s, stripping away much of its functions. Despite calls for Congress to terminate the program, it continued, in large part because by 1992 it had created 75,000 jobs across 39 states.

Grant in which influential lobbies advocated for railroad subsidies and tariffs on wool. Immigration and high birth rates swelled
10368-578: The U.S. risked become a second or third-rate space power. As early as the Reagan Administration, there had been calls for NASA to expand private sector involvement in space exploration rather than do it all in-house. In the 1990s, NASA and Lockheed Martin entered into an agreement to develop the Lockheed Martin X-33 demonstrator of the VentureStar spaceplane, which was intended to replace
10496-569: The US's premier aeronautics agency, NACA formed the core of NASA's new structure by reassigning 8,000 employees and three major research laboratories. NASA also proceeded to absorb the Naval Research Laboratory's Project Vanguard, the Army's Jet Propulsion Laboratory (JPL), and the Army Ballistic Missile Agency under Wernher von Braun . This left NASA firmly as the United States' civil space lead and
10624-538: The White House a little more in favor of the executive branch", according to one account. Past presidents, including Ronald Reagan , George H. W. Bush , Bill Clinton , and George W. Bush , have made public statements when signing congressional legislation about how they understand a bill or plan to execute it, and commentators, including the American Bar Association , have described this practice as against

NASA traces its roots to the National Advisory Committee for Aeronautics (NACA). Despite being the birthplace of aviation, by 1914 the United States recognized that it was far behind Europe in aviation capability. Determined to regain American leadership in aviation,
12928-402: The internal structure of Congress is important to understand along with its interactions with so-called intermediary institutions such as political parties , civic associations , interest groups , and the mass media . The Congress of the United States serves two distinct purposes that overlap: local representation to the federal government of a congressional district by representatives and
13056-486: The lack of term limits favored incumbent white men, making the widow's succession – in which a woman temporarily took over a seat vacated by the death of her husband – the most common path to Congress for white women.

In 2003, a second space shuttle was destroyed when the Columbia was destroyed upon reentry during the STS-107 mission, resulting in the loss of the spacecraft and all seven astronauts. This accident marked the beginning of the retiring of the Space Shuttle program, with President George W. Bush directing that upon the completion of the International Space Station,
15360-731: The spirit of the Constitution. There have been concerns that presidential authority to cope with financial crises is eclipsing the power of Congress. In 2008, George F. Will called the Capitol building a "tomb for the antiquated idea that the legislative branch matters". The Constitution enumerates the powers of Congress in detail. In addition, other congressional powers have been granted, or confirmed, by constitutional amendments. The Thirteenth (1865), Fourteenth (1868), and Fifteenth Amendments (1870) gave Congress authority to enact legislation to enforce rights of African Americans, including voting rights , due process , and equal protection under
15488-579: The use of fuel cells instead of batteries, and conducted the first American spacewalks and rendezvous operations . The Ranger Program was started in the 1950s as a response to Soviet lunar exploration, however most missions ended in failure. The Lunar Orbiter program had greater success, mapping the surface in preparation for Apollo landings and measured Selenography , conducted meteoroid detection, and measured radiation levels. The Surveyor program conducted uncrewed lunar landings and takeoffs, as well as taking surface and regolith observations. Despite

Follow-on missions included the Pioneer Venus project in the 1970s and Magellan , which performed radar mapping of Venus' surface in the 1980s and 1990s. Future missions were flybys of Venus, on their way to other destinations in
15872-434: Was a joint NASA–U.S. Air Force program, with the hypersonic test aircraft becoming the first non-dedicated spacecraft to cross from the atmosphere to outer space. The X-15 also served as a testbed for Apollo program technologies, as well as ramjet and scramjet propulsion. Escalations in the Cold War between the United States and Soviet Union prompted President John F. Kennedy to charge NASA with landing an American on

In
16384-492: Was launched in 1990 on STS-31 from the Discovery and could view galaxies 15 billion light years away. A major defect in the telescope's mirror could have crippled the program, had NASA not used computer enhancement to compensate for the imperfection and launched five Space Shuttle servicing flights to replace the damaged components. The Compton Gamma Ray Observatory was launched from the Atlantis on STS-37 in 1991, discovering
