SpaceX's unmanned Dragon capsule had recently become the first private spacecraft to dock with the International Space station. Although the journey to accomplish it was fueled with a lot of hurdles, which included a last minute abort of the launch, they finally managed to dock with ISS on May 25.

The next day was an accomplishment in its own kind when the hatches between Dragon and the $100 billion orbiting lab were opened.

Now, the astronauts aboard the International Space Station would be unloading cargo from the first private spacecraft ever to visit the orbiting lab.

There are over 1,014 pounds (460 kilograms) of cargo on the Dragon spacecraft and the unpacking would only begin on May 28. According to NASA flight director Holly Ridings, “Monday and Tuesday are very big cargo days on the space station with regard to Dragon. At least one of the crewmembers will be doing cargo operations almost all of their work days those days”.

There are currently six astronauts living aboard the station. They include NASA astronauts Don Pettit and Joe Acaba, European astronaut Andre Kuipers, and Russian cosmonauts Oleg Kononenko, Gennady Padalka and Sergei Revin. The unloading would be handled by Acaba and Kuipers which would take a total of about 25 hours.
