AMERICA’S newest capsule for astronauts is rocketing towards the International Space Station on a test flight by SpaceX.

A Falcon rocket blasted off with the Crew Dragon capsule from Nasa’s Kennedy Space Centre in Florida.

The only passenger is a life-size test dummy, named Ripley from the Alien movies.

It will spend five days docked to the orbiting outpost, before making a splashdown in the Atlantic next Friday – all vital training for the next space demo, possibly this summer, when two astronauts strap in.

“This is critically important... we’re on the precipice of launching American astronauts on American rockets from American soil again for the first time since the retirement of the space shuttles in 2011,” said Nasa administrator Jim Bridenstine.

An estimated 5000 Nasa and contractor employees, tourists and journalists gathered in the wee hours at Kennedy Space Centre with the SpaceX launch team, as the Falcon 9 rocket blasted off.
