The Falcon 9 rocket has been developed and built by the private company SpaceX, with the idea of reusing the parts of the rocket to reduce the price. It has two stages and is 70 meters high. The first stage, after being separated from the rest of the rocket, returns to land on a platform in the sea, or on land. It has landed 51 times and can be reused up to 10 times with little maintenance required. It is then reused on different flights. The second stage burns up in the atmosphere after launch so it is not reused. This rocket was first launched in June 2010 and has had numerous improvements. Versions that have been launched include V1.0 (2010-2013) V1.1 (2013-2016) V1.2 Full Thrust (2015-2018) and Block 5 (2018-).

The Crew Dragon capsule is derived from the Dragon Capsule that has been used to carry cargo to and from the International Space Station to Earth. Both Capsules have been launched a total of 22 times and have reached the ISS 21 times, 9 of those with a reused capsule. In the case of Crew Dragon, the capsule will not be reused to send astronauts, but will be used again to send cargo. It can carry up to 7 astronauts although NASA will only use it for four.

The capsule has 8 Superdraco engines to separate it from the rocket in case something goes wrong (to protect the lives of the astronauts). It would separate the capsule by 800 meters in 8 seconds. It also uses 16 Draco engines to maneuver and move the capsule.

When it returns to earth, the capsule separates the lower part from the upper part. It enters the atmosphere using the heat shield to prevent the capsule from breaking up and splashes down into the Atlantic using four parachutes.

As it is the first time that astronauts are launched with this capsule and rocket, only two will go up, but in next missions they will occupy four places.

Commander - Douglas Hurley. He has previously flown the STS-127 and STS-135 space shuttle missions, spending a total of 28 days 11 hours 12 minutes and 54 seconds in space. He was born in New York in 1966 and attended Tulane University and later the United States Naval Tes Pilot School.

Pilot - Robert Bhenke: Has previously flown the space shuttle missions STS-123 and STS-130 and spent a total of 29 days 12 hours 17 minutes and 18 seconds in space. He was born in Missouri in 1970 and attended Washington University in St Louis and the U.S. Air Force Test Pilot School.
