Frank Lee Culbertson Jr. is an American former naval officer and aviator, test pilot, aerospace engineer, NASA astronaut, graduate of the US Naval Academy, and member of the United States Astronaut Hall of Fame. He served as the commander of the International Space Station for almost four months in 2001 and was the only U.S. citizen not on Earth when the September 11 attacks occurred.
Edward Michael "Mike" Fincke is an American astronaut who formerly held the American record for the most time in space. His record was broken by Scott Kelly on October 16, 2015.
Sunita Lyn "Suni" Williams is an American astronaut, retired U.S. Navy officer, and former record holder for most spacewalks by a woman (seven) and most spacewalk time for a woman. Williams was assigned to the International Space Station as a member of Expedition 14 and Expedition 15. In 2012, she served as a flight engineer on Expedition 32 and then commander of Expedition 33. In 2024, she returned to the ISS on the Boeing Crew Flight Test, the first crewed mission of the Boeing Starliner; her return to Earth has been delayed until February 2025. As such, from August 2024 until February 2025, Williams and fellow astronaut Butch Wilmore are pivoting ahead to undertake various scientific experiments and maintenance tasks aboard the International Space Station.
Eric Allen Boe is a retired United States Air Force fighter pilot, Colonel, test pilot, and a current, active NASA astronaut. He flew as the pilot of Space Shuttle missions STS-126 and STS-133.
Alan Goodwin "Dex" Poindexter was an American naval officer and a NASA astronaut. Poindexter was selected in the 1998 NASA Group (G17) and went into orbit aboard Space Shuttle missions STS-122 and STS-131.
Barry Eugene "Butch" Wilmore is an American NASA astronaut and United States Navy test pilot. He has had three spaceflights, the first of which was an 11-day Space Shuttle mission in November 2009, to the International Space Station. Wilmore was designated as pilot with five other crew members on Space Shuttle Atlantis for the mission STS-129. He served as part of Expedition 41 to the International Space Station, and in 2024 returned to the ISS on the Boeing Crew Flight Test, the first crewed mission of the Boeing Starliner. As of October 2024 he is in space and is set to return to Earth in 2025.
Douglas Gerald Hurley is an American engineer, former Marine Corps pilot, and former NASA astronaut. He piloted Space Shuttle missions STS-127 and STS-135, the final flight of the Space Shuttle program. He launched into space for the third time as commander of Crew Dragon Demo-2, the first crewed spaceflight from American soil since STS-135 and became, together with Bob Behnken, the first astronaut in history launching aboard a commercial orbital spacecraft. He was also the first Marine to fly the F/A-18 E/F Super Hornet. His call sign is "Chunky", and he was sometimes referred to by this name on the communication loops.
STS-135 was the 135th and final mission of the American Space Shuttle program. It used the orbiter Atlantis and hardware originally processed for the STS-335 contingency mission, which was not flown. STS-135 launched on July 8, 2011, and landed on July 21, 2011, following a one-day mission extension. The four-person crew was the smallest of any shuttle mission since STS-6 in April 1983. The mission's primary cargo was the Multi-Purpose Logistics Module (MPLM) Raffaello and a Lightweight Multi-Purpose Carrier (LMC), which were delivered to the International Space Station (ISS). The flight of Raffaello marked the only time that Atlantis carried an MPLM.
The Boeing Starliner is a spacecraft designed to transport crew to and from the International Space Station (ISS) and other low-Earth-orbit destinations. Developed by Boeing under NASA's Commercial Crew Program (CCP), it consists of a reusable crew capsule and an expendable service module.
Development of the Commercial Crew Program (CCDev) began in the second round of the program, which was rescoped from a smaller technology development program for human spaceflight to a competitive development program that would produce the spacecraft to be used to provide crew transportation services to and from the International Space Station (ISS). To implement the program, NASA awarded a series of competitive fixed-price contracts to private vendors starting in 2011. Operational contracts to fly astronauts were awarded in September 2014 to SpaceX and Boeing, and NASA expected each company to complete development and achieve crew rating in 2017. Each company performed an uncrewed orbital test flight in 2019.
The retirement of NASA's Space Shuttle fleet took place from March to July 2011. Discovery was the first of the three active Space Shuttles to be retired, completing its final mission on March 9, 2011; Endeavour did so on June 1. The final shuttle mission was completed with the landing of Atlantis on July 21, 2011, closing the 30-year Space Shuttle program.
Nicole Victoria "Duke" Aunapu Mann is an American test pilot and NASA astronaut. She is an F/A-18 Hornet pilot and a graduate of the US Naval Academy, Stanford University, and the US Naval Test Pilot School. She has over 2,500 flight hours in 25 types of aircraft and 200 carrier landings, and has flown 47 combat missions in Iraq and Afghanistan. Mann completed astronaut training in 2015 and was assigned in August 2018 to Boe-CFT, the first crewed test flight of the Boeing CST-100 Starliner, but subsequently reassigned to the SpaceX Crew-5, becoming the first female commander of a NASA Commercial Crew Program launch.
Boeing Crew Flight Test (Boe-CFT) was the first crewed mission of the Boeing Starliner capsule. Launched on 5 June 2024, the mission flew a crew of two NASA astronauts, Barry E. Wilmore and Sunita Williams, from Cape Canaveral Space Force Station to the International Space Station. The mission was meant to last eight days, ending on 14 June with a landing in the American Southwest. However, the capsule's thrusters malfunctioned as Starliner approached the ISS. After more than two months of investigation, NASA decided it was too risky to return Wilmore and Williams to Earth aboard Starliner. Instead, the Boeing spacecraft returned uncrewed on 7 September 2024, and the astronauts will ride down on the SpaceX Crew-9 spacecraft in February 2025.
Boeing Starliner-1, also called Post Certification Mission-1 (PCM-1), is planned to be the first operational crewed mission of the Boeing Starliner to the International Space Station (ISS) as part of the Commercial Crew Program. It will be the fourth orbital flight mission of the Starliner overall.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
