"NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery."

The NASA Vision note Circa 2025, changes every presidential administration

The National Aeronautics and Space Administration is the U.S. government agency concerned with space exploration, founded in 1958 as the successor to the National Advisory Committee for Aeronautics (NACA). It is not a military agency; it's a civilian agency (although some personnel, particularly astronauts, may be military officers on special assignment to the agency as a tour of duty). Much of the "military vs. civilian" confusion is likely due to the frequent misconception of NASA's responsibilities, as the agency is frequently portrayed as conducting activities—such as tracking objects in Earth orbit, or launching and controlling secret satellites, for example—that generally fall within the purview of military or intelligence communities (most often the United States Air Force, or since 2019 the United States Space Force). Furthermore many astronauts (especially in the early daysnote For instance, all Mercury astronauts, all Gemini astronauts save one, and all Apollo astronauts save two were serving members of the US military at the time of flight—and the Gemini civilian was one of the Apollo ones, as well. The exceptions were Neil Armstrong—who flew on Gemini 8 as well as Apollo 11—who was a former naval aviator, and Harrison Schmitt, a civilian U.S. Geological Survey geologist who flew on Apollo 17) were military officers when they flew.

Generally, a radio transmission addressed to "Houston" (especially from anyone in space) is a reference to NASA's Mission Control Center at Lyndon B. Johnson Space Center in the Texan city of the same name. And no, JSC (or KSC) is not the only NASA center in existence, nor is it the NASA headquarters. In fact, there are nine main NASA facilities note Ames Research Center (in Mountain View, CA, not far from Google's HQ), Armstrong/Dryden Flight Research Center (at Edwards Air Force Base in Southern California), Glenn/Lewis Research Center (at the edge of Cleveland, OH), Goddard Space Flight Center (in Greenbelt, MD, northeast of DC), Johnson Space Center (Houston), Kennedy Space Center (Cape Canaveral, FL), Langley Research Center (Hampton, VA, next to Langley AFB), Marshall Space Flight Center (Huntsville, AL), Stennis Space Center (border of Louisiana and Mississippi between Biloxi and New Orleans), and a bunch of facilities they micromanage alongside Jet Propulsion Laboratory note  a laboratory under the California Institute of Technology (Caltech) but largely funded through NASA, similar to the deal the University of California has with the Department of Energy to fund Lawrence Berkeley National Laboratory in Berkeley in Pasadena, CA, Deep Space Network,note  in Madrid, Spain; Canberra, Australia; Goldstone, California two other tracking stations, two abandoned tracking stations in Australia, the NASA infrared telescope at Mauna Kea on the Big Island of Hawaii, and finally, the NASA Headquarters, located in a fairly nondescript building around the corner of 300 E Street SW, Washington, D.C.. note  the most recent ones, anyways. Past locations include the Little White House and the Cosmo Club. Future locations include the moon.

The Mercury Program

The Russians had put Yuri Gagarin in space, so the US played catch-up. The goal of this program was simply putting Americans in orbit. After a test flight involving Ham the Chimp, Alan Shepard (who ) and John Glenn (the first American in orbit) made their famous flights.

The Right Stuff is a movie about the Mercury astronauts, based on a nonfiction book by Tom Wolfe. The Astronaut Wives Club is a miniseries about their wives, based on a nonfiction book by Lily Koppel.

The manned Mercury missions (and two notable not-technically "manned" missions) are:

The Gemini Program

Within three weeks after the first successful Mercury flight, in mid-1961, President Kennedy announced that the United States should commit to the goal of "landing a man on the Moon and returning him safely to the Earth" before the end of the 1960s. This, of course, meant that they needed a lot of practice. The Gemini Program focused on staying in space for long periods of time in two-person capsules, spacewalking, and rendezvous and docking in orbit.

Despite its crucial importance to the space race, Gemini is the forgotten middle child of the space program. Outside of non-fiction books, the most exposure it's gotten is half of an episode of the HBO Docudrama Mini Series From the Earth to the Moon. There were some proposals to use Gemini as a quicker means of getting (fewer people) to the Moon, or using it as the basis for a larger orbital ship called Big Gemini—these tended to be suppressed by NASA after they had committed to Apollo.

The official pronunciation was "GEM-in-ee".

The Apollo Program

NASA's most famous program. The Apollo spacecraft was a three-person vessel that had three main parts: the Command Module, a squat cone note Actually its profile wasn't a perfect circle, it was very slightly ovoid so that the astronauts would have a little control over its direction during re-entry. Additionally, the cone was truncated and the apex was removed to make way for docking equipment where the crew spent most of their time and which was the only bit that would survive re-entry; the Service Module, a big cylinder where all of the life-support equipment was kept; and the Lunar Module, the funny spidery thing that actually landed on the Moon. Missions to the Moon were propelled by the Saturn V, America's largest ever rocket, and the largest rocket ever successfully used (the Soviet N1 and Energia rockets were larger, but the N1 was a catastrophic failure and kept secret until 1990, and Energia was too expensive to be useful, especially after the Soviet collapse resulted in a near-bankrupt Russia). Notable missions include:

Skylab and the Apollo Applications Program

From the beginning of the Apollo program, NASA had been looking into using spare Apollo hardware for a number of other scientific missions. This outgrowth of Apollo was called the Apollo Applications Program, which proposed a number of ambitious ideas. These included plans for a manned orbital observatory, a Venus flyby using the third stage of the Saturn V as a "wet workshop," and various lunar habitats. The only one of these ideas to reach fruition was Skylab, a Space Station built into an empty stage from a spare Saturn V. Skylab suffered severe damage during its launch in 1973, but the crews that followed it up managed to repair it, and it was inhabited for most of the next nine months. Early shuttle missions were planned to resuscitate the station, but delays to the shuttle program and increased sun activity in 1979 saw Skylab deorbit over Australia on (ironically) July 4, 1979.

Apollo-Soyuz Test Project

A successful docking of an American Apollo and a Soviet Soyuz spacecraft in space in 1975. Generally considered the formal end of The Space Race and is significant for many reasons:

The Space Shuttle

Designed to be the opposite of the Saturn V, the Shuttle note officially called the Space Transportation System in NASA's nomenclature has been described as a "do anything vehicle, but not a go anywhere one": it is a versatile vehicle and was designed to be an economical one. (That's by the standards of space flight to begin with, and it actually ended up costing a lot more per launch than envisioned.) It could not, however, get further than low Earth orbit (though some works of fiction have the Space Shuttle going beyond Earth orbit). The Shuttle was originally proposed as part of a complete infrastructure of American Earth-orbit facilities, including the Space Station Freedom (see below); budgetary cutbacks meant that only one portion of the proposal could be funded, and the Shuttle was selected. Somewhat ironically, it is only in the final stages of its life-cycle that the advent of the International Space Station has allowed the Shuttle to be used in the capacity for which it was originally designed.

Strictly speaking, the big black-and-white thing that looks kind of like an airplane is called an "orbiter"; the space shuttle consists of an orbiter, a large external fuel tank (which is not recovered—a new one must be used every time), and two Solid Rocket Boosters (which were recovered and reused). Six orbiters have been built in total:

The entire space shuttle fleet was decommissioned in 2011, in favor of a new system known as Orion that could have, when using the new Ares-class rockets, been able to go back to the Moon. This new system was soon cancelled, but Orion was moved into the under-development "Space Launch System." See "Project Constellation" for more details.

The International Space Station

An outgrowth of a design project known as Space Station Freedom, which was initiated under the Reagan administration. By the 1980s, the Soviets had wrested back the top dog position in manned spaceflight with the Salyut series of stations. The launch of Mir cemented this. note  Mir was designed with a life of 5 years; it lasted 15 and shrugged off accidents that should have killed it. Mir's modular design (basically being built in parts from different modules launched separately) made it perhaps the first true station of science fiction lore, unlike the preceding ones which were built on the ground and sent up in one package; this permitted a much more capable and advanced station. Not for nothing is Mir considered along with Gagarin and Apollo one of the main achievements of spaceflight in the last century. Space Station Freedom was supposed to be the US's answer. Following a series of budget cutbacks (and a trimmed-down redesign, jokingly known as "Space Station Fred"), the Freedom proposal was abandoned in favor of the ISS, a collaborative project between NASA, the Russian Space Agency, the Canadian Space Agency, the multinational European Space Agency, and the Japan Aerospace Exploration Agency. This orbital science research facility is commanded from mission control centers in Houston, U.S. (which typically has overall operational control); Moscow, Russia; Oberpfaffenhofen, Germany; and Tsukuba, Japan.

It has been said, not entirely inaccurately, that the ISS came about because each member had something they lacked. The Russians lacked money, NASA expertise, and the Canadians, Japanese, and Europeans a human spaceflight program, and ISS rectified this. note  That the Russians got money, NASA got access to Russian know-how, and the Canadians, Japanese, and Europeans a manned space program without the costs and dangers of building their own hardware Launched in 1998 and permanently manned since 2000, it is now the size of a five bedroom suburban house in living space alone, and nearly a million kilograms in mass. The ISS is essentially two stations: the Russian Orbital module (the larger part), which is basically Mir mark 2, and the US Orbital Section, which is a mishmash of sections built by the other partners, though mainly comprised of elements meant for Space Station Freedom, plus the cancelled European station Columbus.

Project Constellation

NASA's latest manned spaceflight project called for the Shuttle to be retired some time around 2010 and replaced by the Orion spacecraft, a semi-reusable capsule similar to the Apollo spacecraft. New rockets were being developed, Ares I and V. The Orion spacecraft, together with the Altair lander, would have been capable of manned lunar missions, near-Earth asteroid encounters, and potentially even interplanetary travel. The first test launch of the program, Ares I-X, took place on October 27, 2009.

In a development that has been controversial to say the least, the 2011 federal budget proposed by President Barack Obama (who was openly hostile towards Constellation, calling it "over-budget, behind schedule, and lacking in innovation") on February 1, 2010 does not include any elements of Constellation, effectively canceling the program to develop the boosters and redefining the Orion capsule as a "Multi-Purpose Crew Module." In its place, the administration has proposed a stronger focus on education and research to develop "game-changing technologies" before continuing with a manned exploration agenda, with American access to the International Space Station delegated to a rapidly-growing commercial spaceflight industry. This has garnered a mixture of both approval and criticism within NASA and within Congress (which has final authority over the budget)—some say that previous exploration goals were too ambitious for current technology, while others insist that if a clear-cut goal for exploration is defined, the required technology will be developed as it is needed (as it was during Apollo). Time will tell what the final outcome is.

The Artemis Program

To replace the Ares boosters as the primary launch vehicle for the Orion/Multi-Purpose Crew Module, NASA has worked on a new booster called the Space Launch System. Reusing as much Space Shuttle hardware as possible, including longer versions of the solid rocket boosters and a four-engine configuration of the RS-25 main engines used by the Space Shuttle, the SLS continues the Ares concept with all flight-tested hardware. Many say the SLS needs a better name, one name kicked around by space enthusiasts being Neptune to follow up on Saturn (as a rocket named Uranus would probably spawn even more juvenile jokes than the planet already has).

In 2019, both Orion and the SLS were integrated into the new Artemis program by the Trump adminstration. The new goal is for a manned lunar landing by 2024 (later delayed to 2026), with at least one woman and one astronaut of color. Said mission, Artemis 3, will have Orion meet up with a SpaceX Starship HLS landing craft in lunar orbit.

After several delays due to problems with the SLS rocket, the first launch of the Artemis program (Artemis 1) took place on November 16, 2022, with the (unmanned) Orion capsule as payload to test its systems in a flight (just orbit) to the Moon.

Commercial Orbital Transportation Services and Commercial Crew Program

Considering the bureaucratic mess involved in developing any kind of American-operated flight hardware for getting to the International Space Station (or beyond) in the post-Shuttle era, NASA has smartly hedged its bets by developing the Commercial Orbital Transportation Services, or COTS, program to help support private companies to develop, build and launch cargo spacecraft for ISS. Basically, private companies take care of the ISS while NASA plays in space with spacecraft funded by taxpayers.

Three companies have contracts. One has a remarkable lead overall: SpaceX. Officially called "Space Exploration Technologies Corporation"note Which sounds like what NASA would've called a private-sector spinoff of itself, to be honest and founded by Paypal and Tesla billionaire Elon Musk, the company has developed its Falcon launch vehicles and its crew/cargo module, the Dragon, and is the first private company to launch a spacecraft to the ISS on May 22, 2012, and dock their vehicle to the ISS. They started operational flights in October 2012. The Dragon and Falcon are designed to be almost-fully reusable, with extremely cool recovery/abort modes that bring expended Falcon boosters back to Earth via a powered rocket landing, Space: 1999 style. Also on the first contract was Orbital ATK (formerly Orbital Sciences) and their Cygnus cargo spacecraft. Despite a catastrophic (and rather spectacular) crash of the ORB-3 cargo rocket in October, 2014, they continued sending supplies thanks to a United Launch Alliance Atlas V launch vehicle until Orbital returned to flight on their Antares rocket by mid-2016.

A second contract of the program has Cygnus and Dragon returning to supply the ISS, plus an unmanned winged vehicle back under NASA's fold: Sierra Nevada Corporation's Dream Chaser Cargo spacecraft. Dream Chaser Cargo adds a second supply vehicle, after Dragon, capable of safely returning unneeded or completed experiments from its glide back to Earth. Unlike the Dragon and Cygnus (both use their own launch vehicle), the DC-Cargo will ride an Atlas V to the ISS.

Getting cargo to the ISS has been comparably easier than getting crew to the station. Until 2011 (with some downtime after the Columbia accident), the Space Shuttle program was the normal means for most Expedition crews to reach and return from the station. With the STS program's end in 2011, NASA rented seats on the Russian Soyuz spacecraft to reach the station, though this is becoming more difficult owing to deteriorating relations between the United States and Russia regarding the Ukraine Crisis and North Korea. It doesn't help that Russia has embargoed the sale of rocket engines for rockets launching military payloads.

To resolve this expensive and somewhat embarrassing hitchhiking, NASA introduced the Commercial Crew Program, a contract that would choose one or two private companies to build and supply new human-rated, reusable spacecraft with launch vehicles. Three companies competed for the contract: SpaceX (already handling cargo runs as well) with a new, sleek Dragon spacecraft, Sierra Nevada Corporation's Dream Chaser mini-shuttle, and the CST-100, a Boeing-led project with a capsule similar in appearance to the old Apollo and Orion spacecraft.

By September 2014, NASA chose SpaceX's Dragon V2 (called by NASA as the "Crew Dragon") and Boeing's CST-100 (now also known as the "Starliner") as the new low-earth-orbit manned ferries to the ISS, leaving the SNC Dream Chaser snubbed as a manned vehicle (although SNC successfully picked up a COTS contract 2 with a smaller unmanned cargo variant noted above). The Dragon V2 started flying crew up in earnest in 2020. The CST-100 did so in 2024, but was plagued with thruster pressurization issues, leaving the astronauts stuck on the ISS for eight months longer than anticipated.

There were quite a few proposals that lobbied to be selected. One of the most interesting came from the United Space Alliance, who wanted to keep Atlantis and Endeavour flying, only commercially instead of at taxpayers' expense; the two shuttles would fly twice a year between 2013 and 2017 (most likely, each shuttle would fly once per year), and would presumably be back to launching commercial and military satellites like they did in the 80s and 90s before the advent of the ISS (flights to the ISS with the commercial shuttles would probably involve crew transfer and resupply with one of the pressurized logistics modules, as the remaining modules can be launched on conventional rockets). As you can imagine, this proposal was not selected, but generally speaking, it was probably the most logical, since all of the Space Shuttle infrastructure was still in place when the proposal was made, and the technology was proven (unlike the other proposals).

Unmanned Missions

There are lots of these, given that robotic probes are much better at traveling far and wide to explore the solar system, not needing any life support, fuel to accelerate astronauts and their support systems to reasonable speeds, more fuel to accelerate that fuel, protection from cosmic rays, landing craft that can take off from other planets/moons, methods of surviving on said other worlds, and usually, no need for return journeys. Also, no lives to be lost, of course. Since mindless robot explorers are not as glamorous or exciting to watch as astronauts, the probe fleet is obviously not as well known as, say, Apollo, but some of them have leaked into the public consciousness nonetheless.

Mars Missions: Venus Missions:

This was more the Soviets' thing, but the US did have a few notable Venus missions.

Mercury Missions:

The exploration of Mercury is quite difficult, as one has to get rid of a lot of the momentum provided by Earth's translation around the Sun but keep enough to safely dodge the Sun and enter Mercury orbit, explaining why just two probes, both from NASA, have reached it

note The European-Japanese BepiColombo is en route towards it

:

The Outer Solar System:

The outer solar system probes, undoubtedly one of NASA's specialities, are generally fly-bys, with a few orbiters and one lander to date. Five of them (The

Pioneers

, the

Voyagers

and

New Horizons

) have achieved escaped velocity for the solar system and are headed out into interstellar space, where they'll roam for millions of years unless picked up by a faster spacecraft at some far future date or, god forbid, extraterrestrials. None, however, are headed for any nearby star, and at the speeds at which they are traveling, they'd take tens of thousands of years to cover the distances to the stars anyway. Most of these probes rely on RTG

note Radioisotope Thermoelectric Generators—not nuclear reactors in the traditional sense, they convert the heat energy from decaying plutonium directly into electricity

units to power themselves; however, the combination of more efficient solar cells and increasingly expensive nuclear fuel has lead to solar power becoming a viable option (such as with

Dawn

and

Juno

).

Solar Missions: Earth Science Missions:

NASA also looks down at Earth. After all, the

Earthrise

is a major symbol of environmental protection. Although not as prominent as other unmanned probes, NASA's Earth science probes have contributed a lot to the climatologist community, looking at things such as deforestation, the ozone holes, ice cap melting, tracking hurricanes, etc.

Here

is a handy list of all of the Earth science probes.

Aviation

The first "A" in NASA stands for Aeronautics, after all. Although NASA's manned space missions get most of the attention, and NASA's unmanned space missions get most of the attention not already garnered by the manned missions, NASA also engages in and/or encourages research into improving flight within Earth's atmosphere.

It was NASA's predecessor, NACA (National Advisory Committee for Aeronautics), for example, who contracted the development of the Bell X-1 rocket plane to break the sound barrier. NASA also led the way with research into the Scramjet for the (now cancelled) National Aerospace Plane, and is looking into laminar airflow to allow supersonic aircraft to cruise more efficiently. In other words, NASA is trying to restart the supersonic airliner industry.

Aeronautical research is mainly conducted in the original NACA centers—Glenn, Ames, Armstrong, and Langley. Chances are, if there is a modern aircraft buzzing overhead, it contains an airfoil from the NACA airfoil series. Famous figures such as Orville Wright and Charles Lindbergh once chaired NACA. A few years before the start of WWII, it was one of NACA's European "spies" that noticed Hitler was a little too suspicious with the constructions of new aeronautical laboratories, all of which had technology that greatly dwarfed NACA's ability. NACA applied to Congress for more research funding, but the Great Depression was still rampaging, so that went nowhere until the war started. Nevertheless, NACA's research helped the development of warplanes during the war.

Everything Else

The geek side of The Internet likes to remind any willing audience that modern NASA doesn't just do spaceflight, manned or unmanned. And they're right—federal charters mandate NASA to perform bioengineering, renewable energy, and climate research, sometimes as complementary to spaceflight research. The details to those "other" researches are outside of this wiki's scope, so here is a brief rundown of what one would expect to turn up when modern "NASA" is mentioned on the Internet:
