Boeing Orbital Flight Test 2
The Boeing Orbital Flight Test-2 (also known as Boe-OFT-2) was a repeat of Boeing's unsuccessful first Orbital Flight Test (Boe-OFT) of its Starliner spacecraft. The uncrewed mission was part of NASA's Commercial Crew Program. OFT-2, using Starliner Spacecraft 2, launched 19 May 2022 and lasted 6 days. Starliner successfully docked with the International Space Station (ISS) on 21 May 2022. It stayed at the ISS for 4 days before undocking and landing in the White Sands Missile Range on 25 May 2022.
The capsule carried approximately 245 kg (540 lb) of supplies and test equipment to simulate future missions with astronauts and their cargo on board. Some of the cargo included flags from historically black colleges and universities and pins of Rosie the Riveter and 16 EMU water absorption pads.
Starliner was loaded with 500 pounds of cargo to bring to the ISS–mostly food with some small EVA components. Astronauts unloaded this cargo and replaced it with 600 pounds of nitrogen-oxygen recharge tanks to take down. Once on the ground, the tanks were to be refurbished and then flown again.
Starliner again carried the Anthropomorphic Test Device (ATD) Rosie (aka "Rosie the Rocketeer") for its second flight. It also carried a plush toy of Kerbal Space Program character Jebediah Kerman as a zero-G indicator.
The first flight of Starliner after the December 2019 OFT-1 flight failed to rendezvous with the station due to software problems. Boeing and NASA agreed on another uncrewed flight test of the spacecraft's systems. As part of the original fixed-price contract this flight was paid by Boeing, at an estimated out-of-pocket cost to Boeing of US$410 million. The mission was planned to use the hardware, Starliner spacecraft, and Atlas V originally planned for use on the Boe-CFT crewed flight test.
The second Atlas V N22, designated AV-082, launched the Starliner spacecraft on its second uncrewed test flight to the International Space Station. The capsule docked with the space station, then returned to Earth to land in the Western United States after an orbital shakedown cruise ahead of Boeing Crewed Flight Test.
OFT-2 was the second flight of an Atlas V without a payload fairing and with a dual-engine Centaur upper stage. The dual-engine Centaur uses two RL10s and is required for Starliner flights in order to provide a launch trajectory that allows a safe abort at any point in the mission.
Boeing modified the design of the Starliner docking system after the OFT-1 flight, adding a hinged re-entry cover below the expendable nosecone for additional protection during the capsule's fiery descent through the atmosphere similar to the one used in the SpaceX Dragon 2 nosecone. This was tested on the OFT-2 mission. This flight also marked the first time that a spacecraft with NASA's docking system docked to the ISS, as Dragon’s docking system was designed by SpaceX themselves.
