President Donald Trump departs Air Force One after arriving at NASA’s Kennedy Space Center Launch and Landing Facility ahead of SpaceX’s Demo-2 mission, Saturday, May 30, 2020, in Florida. NASA’s SpaceX Demo-2 mission is the first launch with astronauts of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. The test flight serves as an end-to-end demonstration of SpaceX’s crew transportation system. Behnken and Hurley are scheduled to launch at 3:22 p.m. EDT on Saturday, May 30, from Launch Complex 39A at the Kennedy Space Center. A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to low-Earth orbit for the first time since the conclusion of the Space Shuttle Program in 2011.

The Space X capsule being tested at NASA Langley’s Splash Test Basin. A series of drop tests into the Hydro Impact Basin at the Landing and Impact Research Facility at NASA’s Langley Research Center in Hampton, Virginia helped SpaceX’s Crew Dragon capsule prepare to safely land astronauts. A mock-up of the capsule with two instrumented crash test devices seated inside was tested in March 2019, representing how the capsule may impact the water during splashdown with different wind and parachute dynamics. Data collected helps understand pressures on the capsule and how those forces affect the spacecraft and occupants. Crew Dragon will carry NASA astronauts Bob Behnken and Doug Hurley to the International Space Station in the Demo-2 mission, the final SpaceX flight test for NASA’s Commercial Crew Program and the first flight of astronauts to orbit from U.S. soil since the space shuttle’s retirement in 2011.

The Space X capsule being tested at NASA Langley’s Splash Test Basin. A series of drop tests into the Hydro Impact Basin at the Landing and Impact Research Facility at NASA’s Langley Research Center in Hampton, Virginia helped SpaceX’s Crew Dragon capsule prepare to safely land astronauts.
