ISS035-E-017699 (10 April 2013) --- This is one of several photos documenting the Multi-user Droplet Combustion Apparatus (MDCA) Fuel Reservoir replacement. Here, Expedition 35 Flight Engineer Chris Cassidy removes and replaces one of the Fuel Reservoirs with the MDCA Chamber Insert Assembly (CIA) pulled partially out of the Combustion Chamber. The MDCA Fuel Reservoirs contain the liquid fuel used during droplet combustion experiments. This reservoir change-out was in support of the FLame EXtinguishment (FLEX)-2 experiment, scheduled to be executed by ground controllers.

ISS035-E-008930 (26 March 2013) ---This image is one of a series of still photos documenting the process to release the SpaceX Dragon-2 spacecraft from the International Space Station on March 26. The spacecraft, filled with experiments and old supplies, can be seen in the grasp of the Space Station Remote Manipulator System’s robot arm or CanadArm2 after it was undocked from the orbital outpost. The Dragon was scheduled to make a landing in the Pacific Ocean, off the coast of California, later in the day.
