SpaceX Crew Dragon is all set for its second flight to ISS. Crew-2 with four astronauts on board will be launched from Launch Complex 39A at the agency`s Kennedy Space Center in Florida. Astronauts will remain aboard the space station for approximately six months as expedition crew members. Crew-1 successfully docked into the ISS in November, last year.
Koch and Meir, clad in white spacesuits and tethered by cords to the station some 254 miles (408 km) above Earth, stepped into outer space at 7:38 am Eastern time (1138 GMT) to replace a faulty power unit designed to help condition energy stored from the station`s solar panels, NASA announced online as it showed live video of the action.
