On April 07, 2010 Space shuttle Discovery (STS-131 flight) docked with the International Space Station at 07:44 UTC.
Discovery delivered to the station new science racks and ammonia tanks. While there, two shuttle astronauts will perform three spacewalks to switch out ammonia tanks on the station.
In the photo: the station's robotic Canadarm2 grapples the Leonardo Multi-purpose Logistics Module (MPLM) from the payload bay of the docked space shuttle Discovery (STS-131) for relocation to a port on the Harmony node of the International Space Station. Attachments: |
