Watch the astronauts give a tour of their new Crew Dragon spacecraft

SpaceX is set to retire its current fleet of Dragon capsules, in use since 2010, next year and begin flying supplies to the International Space Station on a new variant of the Dragon spacecraft based on the model in development to carry astronauts.

SpaceX launched a Falcon 9 rocket from Florida’s Space Coast Wednesday evening with the SES 11/EchoStar 105 communications satellite, a video relay and data distribution platform jointly developed by SES and EchoStar.

A Northrop Grumman Cygnus cargo ship arrived at the International Space Station on Monday, delivering nearly four tons of supplies and experiments to the research lab and its crew, including a $23 million titanium toilet and a high-definition virtual reality camera planned for use on a future spacewalk.
