A trash-filled Russian cargo resupply craft will undock Tuesday at 9:59 a.m. EDT from the Zvezda service module’s aft port. Commander Pavel Vinogradov closed the ISS Progress 51 vehicle’s hatch Monday.

After undocking, the Progress 51 will remain in orbit a few days for engineering tests before re-entering the Earth’s atmosphere for a fiery disposal over the Pacific Ocean. NASA TV coverage of the undocking begins at 9:30 a.m.

The open port on Zvezda will be occupied once again when Europe’s Automated Transfer Vehicle-4 (ATV-4) automatically docks June 15. Nicknamed the “Albert Einstein,” the ATV-4 launched June 5 to deliver cargo, experiment hardware and supplies. Also aboard the ATV-4 are propellant, water and oxygen and air.

Flight Engineers Fyodor Yurchikhin and Alexander Misurkin are preparing their Orlan spacesuits for a June 24 spacewalk. The duo will conduct a six-hour spacewalk to prepare the International Space Station for a new module, the “Nauka” Multipurpose Laboratory Module, due for launch atop a Russian Proton rocket at the end of this year. The “Nauka” will be docked to the Earth-facing port on Zvezda.

NASA Astronauts Karen Nyberg and Chris Cassidy and ESA astronaut Luca Parmitano, all flight engineers, got together Monday to talk to public school students from Douglas, Mass. The event is part of a series that connects students on Earth with astronauts in space to promote science, technology, engineering and math (STEM) programs.

Earlier all six Expedition 36 crew members performed an emergency drill. The onboard training allows the crew to practice communication and coordination skills during a simulated emergency scenario. The station residents practiced the drill in conjunction with the mission control centers in Houston and Moscow. Afterwards the crew huddled together for a ground conference to review the results.

Cassidy worked on science hardware inside the Fluids Integrated Rack. He configured its Light Microscopy Module for the Advanced Colloids Experiment by checking and installing parts such as lenses and a camera.

Throughout the day Nyberg and Parmitano worked on plumbing tasks inside the station. First, Nyberg removed a depressurization hose in the Tranquility Node’s urine processing assembly. Later, Parmitano replaced a urine receptacle and filter inside Tranquility’s Waste and Hygiene Compartment.
