Crew Dragon was designed with three windows so passengers can take in views of Earth, the Moon and the wider solar system right from their seats. Crew Dragon has an Environmental Control and Life Support System (ECLSS) that provides a comfortable and safe environment for crew members. During their trip, astronauts on board can set the spacecraft’s interior temperature to between 65 and 80 degrees Fahrenheit. Crew Dragon features an advanced abort system with eight SuperDraco engines and a series of parachutes that can be activated instantaneously from the moment they are armed on the launch pad all the way through orbital insertion. SpaceX has designated two U.S. offshore splashdown sites for the Crew Dragon. The primary splashdown location is in the Atlantic Ocean offshore from Cape Canaveral, Florida. The secondary splashdown location is in the Gulf of Mexico, ranging from south of Brownsville, Texas, to an area north of the Florida Keys up to 170 nautical miles offshore. In August 2018, NASA announced the first astronauts who will fly aboard Demo-2 and SpaceX's first operational mission, or Crew-1. In Demo-2, NASA astronauts Bob Behnken and Doug Hurley will be the first to fly aboard Crew Dragon. The Demo-2 flight test is part of the path to certification for Crew Dragon. Following the successful Demo-2 flight test and completion of the NASA certification process, SpaceX will begin regular crew rotation missions to the space station, beginning with Crew-1. Those assigned to Crew-1 are NASA astronauts Victor Glover, Mike Hopkins, Shannon Walker and JAXA astronaut Soichi Noguchi. NASA has ordered six crew rotation missions to the International Space Station from SpaceX. Crew-1 will be the first of these rotation missions.
