Nasa SpaceX mission: Dragon capsule docks with space station

The Dragon capsule docked at 04:01 GMT as the station flew over the US state of Idaho


The four astronauts who left Earth on Monday (GMT) have arrived at the International Space Station (ISS).

Their SpaceX Dragon capsule made a series of inch-perfect manoeuvres to bring them into an attachment position on the front of the orbiting lab.

Commander Mike Hopkins, Shannon Walker, Victor Glover and Soichi Noguchi will be spending the next six months aloft.

They join three individuals already aboard – Kate Rubins, Sergey Ryzhikov and Sergey Kud-Sverchkov.

Raising the resident complement to seven individuals will triple the amount of microgravity science that can be conducted on the 410km-high outpost, the US space agency Nasa says.

The Dragon docked at 04:01, just as the station was flying over the US state of Idaho.

The incoming crew had to wait for seal and pressure checks before the hatches between the Dragon and the ISS could be opened. But once this was completed, they were able to enter their new home.

Mike Hopkins said his team had had an amazing ride up from Earth.

“I can’t tell you how excited we were when that rocket lifted off the pad, and then the last 27 hours have gone really smooth,” he radioed down to Earth.

“We are so excited to be here. We are humbled and we are excited to be a part of this great expedition. And we are looking forward to the next six months and can’t wait to get started.”

Joint crews


The capsule commander and his colleagues are the first crew rotation to be brought up to the station on a fully certified, commercial human transportation system, hence their tagline – Crew-1.

The Falcon rocket and Dragon capsule they used to get off Earth is a service the Californian firm SpaceX now sells to Nasa. And the agency has a contract with the company for a further five crew rotations after this one.

It’s a new way of doing business for Nasa, who always used to own and operate the hardware needed to get astronauts into low-Earth orbit.

Now that the agency can source taxi rides from a private supplier, it is focussing its efforts on developing a rocket and capsule for the more challenging task of taking people back to the Moon, something it hopes to do later this decade.

Hopkins’ team has a full programme of research ahead of it. An example experiment involves chips with tissue that mimics the structure and function of human organs, to try to understand the role of microgravity on human health and disease.

The crew will go on at least four spacewalks outside the station.

One of these activities is expected to result in the installation of the first significant UK industrial contribution to the platform.

This is the ColKa communications terminal. Made by MDA UK, the radio equipment will enable astronauts to connect with scientists and family on Earth at home broadband speeds. ColKa will be fixed to the exterior of the European Space Agency’s ISS research module, Columbus.

SpaceX Crew-1: A mission of firsts

  • First fully certified commercial system designed for crew transport
  • First Federal Aviation Administration-licensed human orbital launch
  • First international crew of four to launch on a US commercial capsule
  • First African-American (Victor Glover) to live for 6 months on the ISS
  • First baby Yoda to go into orbit as a microgravity indicator

The crew will also see a wide variety of space vehicles come and go during their time aboard.

Among these vehicles should be the Boeing aerospace corporation’s Starliner capsule.

Like the SpaceX Dragon ship, Starliner is being offered to Nasa and its partner agencies on a commercial basis to ferry astronauts to and from the ISS.

“Low-Earth orbit for over 50 years was the domain of governments. Now, we’ve seen commercial companies, SpaceX being the first, take astronauts to the space station, with Boeing set to follow, hopefully sometime next year,” commented former Nasa astronaut Leroy Chiao.

“It very much follows the aviation era where airliners used to be government run, and now of course they’ve been commercial for a number of decades,” the shuttle and Soyuz flier told BBC News.
