Nasa astronauts Doug Hurley and Bob Behnken have arrived at the Kennedy Space Center in Florida to prepare for their historic mission next week.

The pair’s flight to the International Space Station (ISS) will be made in a rocket and capsule system provided by a commercial company, SpaceX.

Nasa has traditionally always owned and operated its space vehicles.

But that is a capability it gave up in 2011 when it retired the last of the space shuttles.

The agency now intends to contract out all future crew transportation to low-Earth orbit.

Hurley and Behnken flew into Florida from the agency’s human spaceflight headquarters in Texas where they have been in quarantine.

They’ll continue protecting their health at Kennedy as they get ready for Wednesday’s planned lift-off.

The astronauts will do a dummy run to get ready for launch, even climbing into their capsule

Their rocket, a Falcon-9, and capsule, known as Dragon, will be wheeled out to the spaceport’s famous launch pad – complex 39A – in the next few days for its static fire test.

This will see the Falcon ignite briefly all nine of its first-stage engines to check they are fit to go.

Hurley and Behnken, together with ground-support staff, will also conduct a “crew dry dress” rehearsal.

This will involve the men suiting up, riding out to the pad and even climbing into their capsule as a dummy run to ensure everyone understands their role.

Hurley and Behnken will ride to orbit in the SpaceX Dragon capsule

Next week’s launch is key moment in Nasa’s strategy to change the way it conducts its space activity.

Its commercial crew programme, initiated in 2010, selected both SpaceX and aerospace heavyweight Boeing to develop crew transportation services.

The arrangement with the companies means they can also sell seats in their vehicles to other space agencies, companies or indeed wealthy individuals.

For the moment, this model only covers flights to a few hundred kilometres above the Earth, to the ISS. But eventually the aim is to extend the concept to operations in deeper space.

In April, Nasa asked three teams to develop ideas for landing its astronauts on the Moon.

Again, this would be a service the agency would purchase.

Lift-off for Hurley and Behnken next Wednesday is scheduled for 16:33 local time (21:33 BST/20:33 GMT).
