A spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.
A space station is a spacecraft which remains in orbit and hosts humans for extended periods of time. It therefore is an artificial satellite featuring habitation facilities. The purpose of maintaining a space station varies depending on the program. Most often space stations have been research stations, but they have also served military or commercial uses, such as hosting space tourists.
Human spaceflight programs have been conducted, started, or planned by multiple countries and companies. Until the 21st century, human spaceflight programs were sponsored exclusively by governments, through either the military or civilian space agencies. With the launch of the privately funded SpaceShipOne in 2004, a new category of human spaceflight programs – commercial human spaceflight – arrived. By the end of 2022, three countries and one private company (SpaceX) had successfully launched humans to Earth orbit, and two private companies had launched humans on a suborbital trajectory.
Launch Complex 39A (LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida. The pad, along with Launch Complex 39B, was first constructed in the 1960s to accommodate the Saturn V launch vehicle, and has been used to support NASA crewed space flight missions, including the historic Apollo 11 moon landing and the Space Shuttle. The site is currently leased by SpaceX and supports launches of the Falcon 9 and Falcon Heavy rockets.
Katherine Megan McArthur is an American oceanographer, engineer, and NASA astronaut. She has served as a Capsule Communicator (CAPCOM) for both the Space Shuttle and International Space Station (ISS). Megan McArthur has flown one Space Shuttle mission, STS-125 and one SpaceX mission, SpaceX Crew-2 on Crew Dragon Endeavour. She is known as the last person to be hands on with the Hubble Space Telescope via the Canadarm. McArthur has served in a number of positions including working in the Shuttle Avionics Laboratory (SAIL). She is married to fellow astronaut Robert L. Behnken.
Shannon Walker is an American physicist and a NASA astronaut selected in 2004. She launched on her first mission into space on June 25, 2010, onboard Soyuz TMA-19 and spent over 163 days in space.
An EXpedite the PRocessing of Experiments to Space Station (ExPRESS) Logistics Carrier (ELC) is an unpressurized attached payload platform for the International Space Station (ISS) that provides mechanical mounting surfaces, electrical power, and command and data handling services for Orbital Replacement Units (ORUs) as well as science experiments on the ISS. The ELCs were developed primarily at the Goddard Space Flight Center in Greenbelt, Maryland, with support from JSC, KSC, and MSFC. ELC was formerly called "Express Pallet" and is the unpressurized counterpart to the pressurized ExPRESS Rack. An ELC provides scientists with a platform and infrastructure to deploy experiments in the vacuum of space without requiring a separate dedicated Earth-orbiting satellite.
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft.
Thomas Gautier Pesquet is a French aerospace engineer, pilot, European Space Agency astronaut, actor, musician, and writer. Pesquet was selected by ESA as a candidate in May 2009, and he successfully completed his basic training in November 2010. From November 2016 to June 2017, Pesquet was part of Expedition 50 and Expedition 51 as a flight engineer. Pesquet returned to space in April 2021 on board the SpaceX Crew Dragon for a second six-month stay on the ISS.
Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of a reusable space capsule and an expendable trunk module, has two variants: the 4-person Crew Dragon and Cargo Dragon, a replacement for the Dragon 1 cargo capsule. The spacecraft launches atop a Falcon 9 Block 5 rocket, and the capsule returns to Earth through splashdown. Since 2020, when Dragon 2 flew its first crewed and uncrewed flights, it has proven to be the most cost-effective spacecraft ever used by NASA.
Expedition 65 was the 65th long duration expedition to the International Space Station. The mission began on 17 April 2021 with the departure of Soyuz MS-17 and was initially commanded by NASA astronaut Shannon Walker serving as the third female ISS commander, who launched in November 2020 aboard SpaceX Crew-1 alongside NASA astronauts Michael S. Hopkins and Victor J. Glover, as well as JAXA astronaut Soichi Noguchi. They were joined by the crew of Soyuz MS-18, which is made up of Russian cosmonauts Oleg Novitsky and Pyotr Dubrov, as well as NASA astronaut Mark Vande Hei.
The Artemis program is a Moon exploration program led by the United States' National Aeronautics and Space Administration (NASA), formally established in 2017 via Space Policy Directive 1. It is intended to reestablish a human presence on the Moon for the first time since the Apollo 17 mission in 1972. The program's stated long-term goal is to establish a permanent base on the Moon to facilitate human missions to Mars.
SpaceX CRS-23, also known as SpX-23, was a Commercial Resupply Service mission to the International Space Station, successfully launched on 29 August 2021 and docking the following day. The mission was contracted by NASA and was flown by SpaceX using the Cargo Dragon C208. This was the third flight for SpaceX under NASA's CRS Phase 2 contract awarded in January 2016. It was the second mission for this reusable capsule.
SpaceX Crew-3 was the Crew Dragon's third NASA Commercial Crew operational flight, and its fifth overall crewed orbital flight. The mission successfully launched on 11 November 2021 at 02:03:31 UTC to the International Space Station. It was the maiden flight of Crew Dragon Endurance.
Polaris Dawn was a private crewed spaceflight operated by SpaceX on behalf of Shift4 CEO Jared Isaacman, the first of three planned missions in the Polaris program. Launched 10 September 2024 as the 14th crewed orbital flight of a Crew Dragon spacecraft, Isaacman and his crew of three — Scott Poteet, Sarah Gillis and Anna Menon — flew in an elliptic orbit that took them 1,400 kilometers (870 mi) away from Earth, the farthest anyone has been since NASA's Apollo program. They passed through parts of the Van Allen radiation belt to study the health effects of space radiation and spaceflight on the human body. Later in the mission, the crew performed the first commercial spacewalk.
The Polaris program is a private spaceflight program organized by entrepreneur Jared Isaacman. Building on his experience as commander of the Inspiration4 mission—the first all-civilian spaceflight—Isaacman contracted with SpaceX to establish Polaris. The program involves two missions using SpaceX's Crew Dragon spacecraft and is planned to culminate in the first crewed launch on Starship.
Fram2 is a planned private human spaceflight mission, operated by SpaceX on behalf of entrepreneur Chun Wang. During the mission, the 16th crewed orbital flight of a Crew Dragon spacecraft, Wang and his all-civilian crew — Jannicke Mikkelsen, Eric Philips and Rabea Rogge — will be propelled into a polar orbit, a first for a human spaceflight mission. During the three to five day mission, the crew says they will conduct scientific research.
