SpaceX’s Dragon spacecraft successfully separates from the second stage of the company’s Falcon 9 rocket during NASA’s SpaceX 28th commercial resupply services mission to the International Space Station. Liftoff occurred at 11:47 a.m. EDT on June 5, 2023, from NASA Kennedy Space Center’s Launch Complex 39A in Florida.
SpaceX plans to reuse the Cargo Dragons up to five times. The Cargo Dragon launches without SuperDraco abort engines, without seats, cockpit controls and the life support system required to sustain astronauts in space.
The four members of NASA’s SpaceX Crew-6 mission move their Dragon Endeavour spacecraft between docking ports on the International Space Station. Aboard are: NASA astronauts Steve Bowen and Woody Hoburg, UAE astronaut Sultan Alneyadi, Roscosmos cosmonaut Andrey Fedyaev.
The crew will undock from the space-facing port of the station’s Harmony module, then dock at the station’s forward Harmony port. Endeavour is relocating to make room for SpaceX’s 28th cargo resupply mission, currently scheduled to arrive in June.
NASA’s SpaceX Crew-1 mission gets underway with the successful liftoff of the company’s Falcon 9 rocket and Crew Dragon spacecraft carrying NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japan Aerospace Exploration Agency astronaut Soichi Noguchi. Launch occurred November 15, 2020, at 7:27 p.m. EST from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Crew-1 is the first regular crew mission of a U.S. commercial spacecraft with astronauts to the International Space Station as part of NASA’s Commercial Crew Program.
After the Space Shuttle program was brought to an end in 2011, NASA no longer had a spacecraft system capable of sending humans to space. As a result, it was forced to fly its astronauts to the International Space Station (ISS) aboard the Russian Soyuz space vehicle, at a cost of up to US$80 million per astronaut. As an alternative, NASA contracted with private companies such as SpaceX for the Commercial Crew Program, which is expected to cost 50% less than Soyuz once in regular operation. Up to the launch, NASA has awarded a total of US$3.1 billion for the development of the Dragon 2. The Demo-2 mission is expected to be SpaceX’s last major test before NASA certifies it for regular crewed spaceflights. Prior to that, SpaceX had sent twenty cargo missions to the ISS, but never a crewed one.
Crew Dragon Demo-2 (officially Crew Demo-2, SpaceX Demo-2, or Dragon Crew Demo-2) was the first crewed test flight of the Crew Dragon spacecraft. The spacecraft, named Endeavour, launched on 30 May 2020 at 19:22:45 UTC and carried NASA astronauts Douglas Hurley and Robert Behnken to the International Space Station in the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission, STS-135, in 2011, and the first ever operated by a commercial provider. Demo-2 was also the first two-person orbital spaceflight launched from the United States since STS-4 in 1982.
Demo-2 was intended to complete the validation of crewed spaceflight operations using SpaceX hardware and to receive human-rating certification for the spacecraft, including astronaut testing of Crew Dragon capabilities on orbit. During their time aboard, Behnken conducted four spacewalks with fellow American astronaut Chris Cassidy to replace batteries brought up by a Japanese cargo vehicle.
Docking and undocking operations were autonomously controlled by the Crew Dragon, but monitored by the flight crew in case manual intervention becomes necessary. The spacecraft soft docked with the International Space Station at 14:16 UTC on 31 May 2020. Following soft capture, 12 hooks were closed to complete a hard capture 11 minutes later. Hurley and Behnken worked alongside the crew of Expedition 63 for 62 days. Endeavour autonomously undocked from the station at 23:35 UTC on 1 August 2020 and returned the astronauts to Earth on 2 August 2020 in the first water landing by astronauts since 1975.
Endeavour will be refurbished and reused for the SpaceX Crew-2 mission, expected to launch in February 2021. Crew Dragon’s next mission, SpaceX Crew-1 — SpaceX’s first operational astronaut flight — is slated to fly with four Expedition 64 astronauts in late September 2020.
Dragon 2 is a class of reusable spacecraft developed and manufactured by U.S. aerospace manufacturer SpaceX, intended as the successor to the Dragon cargo spacecraft. The spacecraft launches atop a Falcon 9 Block 5 rocket and returns via ocean splashdown. When compared to Dragon, Crew Dragon has larger windows, new flight computers and avionics, redesigned solar arrays, and a modified outer mold line.
The spacecraft has two planned variants – Crew Dragon, a human-rated capsule capable of carrying up to seven astronauts, and Cargo Dragon, an updated replacement for the original Dragon. Crew Dragon is equipped with an integrated launch escape system in a set of four side-mounted thruster pods with two SuperDraco engines each. Crew Dragon has been contracted to supply the International Space Station (ISS) with crew under the Commercial Crew Program, with the initial award occurring in October 2014 alongside Boeing CST-100 Starliner. Crew Dragon’s first non-piloted test flight to the ISS launched in March 2019.
SpaceX conducted an in-flight abort test from Kennedy Space Center Launch Complex 39A in Florida on 19 January 2020 at 15:30 UTC. The Crew Dragon test capsule was launched in an atmospheric flight to conduct a separation and abort scenario in the troposphere at transonic velocities, at max Q, where the vehicle experiences maximum aerodynamic pressure. The test objective was to demonstrate the ability to safely move away from the ascending rocket under the most challenging atmospheric conditions of the flight trajectory, imposing the worst structural stress of a real flight on the rocket and spacecraft. The abort test was performed using a regular Falcon 9 Block 5 rocket.
