Q&A with Tim Ellis, CEO and co-founder of Relativity Space (members only)

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral at 1:50 a.m. EDT (0550 GMT) Sunday with the Telstar 19 VANTAGE communications satellite, a powerhouse spacecraft designed to beam broadband and in-flight WiFi signals across the Americas and the North Atlantic. The rocket’s first stage successfully landed at sea aboard SpaceX’s drone ship.

The nuclear power generator for NASA’s Perseverance rover has been installed on the spacecraft atop an Atlas 5 rocket at Cape Canaveral, and mission managers gave a green light Wednesday to continue preparations for the rover’s July 30 launch toward Mars.

NASA says it is interested in flying astronauts and scientists on commercial suborbital vehicles, like those being tested by Virgin Galactic and Blue Origin, to provide additional training and research opportunities augmenting missions to the orbiting International Space Station.
