Nasa SpaceX launch: Astronaut crew heads to orbit

Four astronauts - three from the US and one from Japan - have launched from Florida on a mission to the International Space Station (ISS).The crew rode to orbit in a rocket and capsule provided by the SpaceX company.It's only the second time the firm has supplied the service.The US space agency Nasa has said it is now entering a new era in which routine astronaut journeys to low-Earth orbit are being conducted by commercial providers.The four individuals making their way up to the ISS are the Americans Michael Hopkins, Victor Glover and Shannon Walker, and the highly experienced Japanese space agency (Jaxa) astronaut Soichi Noguchi.By participating in this mission, Noguchi becomes only the third person in history to leave Earth in three different types of space vehicle, having previously flown on Soyuz and shuttle hardware.What is the SpaceX Crew Dragon?How astronaut transportation went commercialOrbital apparel: Evolution of the spacesuitIMAGE COPYRIGHTEPAimage captionThe traditional "walk-out": The suited crew waved to family and friendsThe crew's Falcon rocket and Dragon capsule left the pad at the Kennedy Space Center at 19:27 local time (00:27 GMT, Monday).It will take just over a day to reach the station. A docking with the orbiting platform is set for about 0400 GMT on Tuesday.When the team arrives, it will join Nasa's Kate Rubins and Russian space agency (Roscosmos) cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov.Having seven people on the 410km-high outpost will triple the amount of science that can be performed in its special microgravity environment.IMAGE COPYRIGHTREUTERSimage captionThe crew was driven down to the launch pad in a convoy of Tesla electric carsSpaceX has signed contracts with Nasa valued in excess of $3bn (£2.3bn) to develop, test and fly an astronaut taxi service.As part of this relationship, the company ran a demonstration mission in May in which astronauts Doug Hurley and Bob Behnken were taken to the station and then returned safely to Earth.The contracted arrangements also call for six "operational", or routine, missions - this flight being the first.Nasa has a similar deal with the Boeing aerospace company, although its service is more than a year behind SpaceX.
