SpaceX Demo-2 (also referred to as Crew Demo-2, SpaceX Demonstration Mission 2, Dragon Crew Demo-2, and Launch America) is the first crewed test flight of the Crew Dragon spacecraft,[8] for launch to the International Space Station on 30 May 2020 at 19:22:45 UTC. Demo-2 is the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission, STS-135, in 2011. Douglas Hurley is spacecraft commander on Crew Dragon Demo-2, joined by Robert L. Behnken as joint operations commander. Crew Dragon Demo-2 is also the first two-person orbital spaceflight launched from the United States since STS-4 in 1982.

The first attempt to launch on 27 May 2020 was aborted due to bad weather caused by Tropical Storm Bertha 16 minutes and 53 seconds prior to launch. A second attempt launched successfully on 30 May 2020 at 19:22:45 UTC.

Mission
The Crew Dragon Demo-2 mission is intended to complete the validation of human-rated spaceflight operations using SpaceX hardware. If successful, the demonstration flight will allow for human-rated certification of the Crew Dragon spacecraft, and the Falcon 9 rocket, the crew transportation system, launch pad, and SpaceX's capabilities. The mission includes astronaut testing of Crew Dragon capabilities on orbit.

The Crew Dragon capsule launched atop a Falcon 9 rocket from Kennedy Space Center Launch Complex 39A on 30 May 2020, and will dock to pressurised mating adapter PMA-2 on the Harmony module of the ISS on 31 May 2020. Hurley and Behnken will work alongside the crew of Expedition 63 for 30 to 90 days, meaning the landing of the spacecraft will occur no later than 28 August 2020.

Docking and undocking operation will be autonomously controlled by the Crew Dragon spacecraft, but monitored by the flight crew in case manual intervention becomes necessary.

The first stage booster landed autonomously on the floating barge Of Course I Still Love You, which was prepositioned in the Atlantic Ocean.

Upon returning to Earth, the Crew Dragon capsule will splashdown into the Atlantic Ocean, where it will be recovered by the Go Navigator recovery vessel.[14]

NASA calculated Loss Of Crew (LOC) probability for test flight is 1-in-276, even lower than the commercial crew program requirement threshold of 1-in-270. The 1-in-276 number includes mitigations to reduce the risk, such as on-orbit inspections of the Crew Dragon spacecraft once it is docked at the space station to look for damage from micrometeoroids and orbital debris (MMOD). NASA pegs the overall risk of a Loss Of Mission (LOM) is 1-in-60. That risk covers scenarios where the Crew Dragon does not reach the space station as planned, but the crew safely returns to Earth.

An official launch weather forecast for Dragon Crew Demo-2 by the 45th Weather Squadron of the U.S. Space Force, for the original launch time at 20:33:33 UTC on 27 May, predicted a 50% probability of favorable conditions. The launch was scrubbed at 16 minutes and 53 seconds before launch due to thunderstorms and light rain in the area. The second and successful launch took place on 30 May 2020 at 19:22:45 UTC with a 50% probability of favorable conditions. The other launch windows were 31 May 2020 at 19:00:07 UTC with a 60% probability of favorable conditions and 2 June at 18:13 UTC with a 70% probability of favorable conditions.
