The SpaceX Demonstration Mission 1 , or SpX-DM1 or Demo-1 for short , was the first unmanned orbital flight of the reusable American spaceship Crew Dragon .

After the pad abort test , the SpX-DM1 mission was the second launch of a Crew Dragon, but its first flight on a launcher, the Falcon 9 .

Mission history

The spacecraft developed by SpaceX and intended for both manned and unmanned missions took off without a crew on this first orbital test flight on March 2, 2019. The course of the flight corresponded exactly to that which was planned for the first manned mission. The next day, it docked fully automatically with the International Space Station (ISS). It was the first automatic docking maneuver of a US spacecraft at the ISS and the first docking maneuver of a spacecraft with docking nozzles of the new International Docking System Standard (IDSS).

The undocking maneuver took place on March 8, 2019. Then the spaceship landed on parachutes off the coast of Florida in the Atlantic . All previous Dragon landings had been in the Pacific .

Reactions

US President Donald Trump congratulated SpaceX on its success five days before the end of the mission. After the successful landing on March 8, the previous US President Barack Obama and the head of the Russian space agency Roscosmos , Dmitri Rogozin , congratulated . Roskosmos had previously shown skepticism and ordered that the ISS commander Oleg Kononenko get to safety behind four closed bulkheads while the Crew Dragon capsule docks.

Steve Stich, Deputy Head of the Commercial Crew Program of NASA , was pleased with the progress of the demonstration mission. The received in-flight measurements have shown that the performance ( performance ) of the spaceship was better than expected, and that docking "phenomenal" and undocking have to work properly. The heat protection system on landing also worked well. But there are still further measurement data to be evaluated.

The live coverage of the DM1 mission, jointly designed by SpaceX and NASA, was awarded an Emmy in the Outstanding Interactive Program category. It is one of around 120 categories in which the 2019 Emmy was awarded.

Subsequent Crew Dragon missions

Further planning envisaged overhauling the spaceship and using it in June 2019 for the so-called in-flight abort test, in which the space capsule's rescue system is triggered in flight. Originally, this test was supposed to take place before SpX-DM1; however, the flight to the ISS was brought forward. In the summer of 2019, a manned flight with a newly built Crew Dragon capsule and the SpX-DM2 mission should take place, the first manned US space flight since the last space shuttle flight STS-135 in 2011.

However, six weeks after being recovered from the Atlantic, the DM1 Dragon capsule exploded during an engine test on a test stand. Nobody was harmed, but the further scheduling became obsolete for the time being.
