Universe Today offers some context for this rather awesome photo:
Following the flawless blastoff of the SpaceX Falcon 9 booster and Dragon cargo ship on Tuesday, April 14, the resupply vessel arrived at the International Space Station April 17, and was successful snared by the outpost’s resident Star Trek crewmate, Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency ...
Cristoforetti grappled the SpaceX Dragon freighter with the station’s robotic arm at 6:55 a.m. EDT, with the able assistance of fellow crewmate and Expedition 43 Commander Terry Virts of NASA.
Dragon is hauling critical supplies to the six astronauts and cosmonauts serving aboard, that now includes the first ever ‘One-Year Mission’ crew comprising NASA’s Scott Kelly and Russia’s Mikhail Kornienko.
