Expedition 50 robotic arm operators Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) commanded the International Space Station’s Canadarm2 robotic arm to release the Cygnus spacecraft at 8:22 a.m. EST while the space station was flying 251 miles over the Pacific Ocean, off the west coast of Colombia. Earlier, ground controllers detached Cygnus from the station and maneuvered it into place for its departure.

Once Cygnus is a safe distance away from the station, ground controllers at Glenn Research Center in Cleveland, Ohio and at Orbital ATK in Dulles, Virginia, will activate the Saffire-II experiment.

Cygnus also will release four LEMUR CubeSats from an external deployer on Friday, Nov. 25, sending them to join a remote sensing satellite constellation that provides global ship tracking and weather monitoring.

The spacecraft will remain in orbit until Sunday, Nov. 27, when its engines will fire twice, pushing it into Earth’s atmosphere, where it will burn up over the Pacific Ocean.

The Cygnus resupply craft launched Oct. 17 on an Antares rocket from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia, for the company’s sixth NASA-contracted commercial resupply mission. The company’s seventh contracted resupply mission is targeted for spring 2017 on an Atlas V rocket from Cape Canaveral Air Force Station in Florida.

Staying behind with Whitson will be European Space Agency astronaut Thomas Pesquet and cosmonaut Oleg Novitskiy of Roscosmos. This will be Whitson’s second stint as commander of the orbital laboratory having last led the Expedition 16 crew in 2008.

Back in Russia, two Expedition 51 crewmates, Jack Fischer of NASA and Fyodor Yurchikhin of Roscosmos, have completed their final qualification exams. They will fly to Kazakhstan on Wednesday for ceremonial duties, check out their Soyuz MS-04 rocket and wrap up mission training before launching from the Baikonur Cosmodrome.

Fluid Physics and Human Research Before Second Spacewalk

PMA-3 Relocation — The Pressurized Mating Adapter-3 is in the grip of the Canadarm2 robotic arm during its relocation and attachment to the Harmony module on March 26,2017.

The crew researched the effects of living in space and set up a specialized microscope for a physics experiment today. Two astronauts are also getting ready for a Thursday spacewalk to continue setting up the International Space Station for commercial crew vehicles.

Flight Engineers Peggy Whitson and Thomas Pesquet used a tape measure this morning and measured their arms, legs, hips, waist and chest. Researchers are studying how microgravity impacts body size and shape and are comparing crew measurements before, during and after a space mission.

Whitson later began setting up gear for the ACE-T-1 (Advanced Colloids Experiment Temperature Control-1) physics study. She opened up the Fluids Integrated Rack and reconfigured the Light Microscopy Module to research tiny suspended particles designed by scientists and observe how they form organized structures within water.

Commander Shane Kimbrough is getting ready for another spacewalk on Thursday at 8 a.m. EDT. This time he’ll go outside with Whitson to finish cable connections at the Harmony module where the Pressurized Mating Adapter-3 (PMA-3) was robotically attached on Sunday. The PMA-3 relocation gets the adapter ready for the new International Docking Adapter-3 set to be delivered on a future cargo mission.

Weekend Robotics Work Sets Up Thursday Spacewalk

The Pressurized Mating Adapter-3 (PMA-3) was robotically removed Sunday from the Tranquility module and attached to the Harmony module after being prepared during a successful spacewalk Friday. A second spacewalk is scheduled for Thursday at 8 a.m. EDT to finalize the PMA-3 cable connections on Harmony.

Download hi-res video of briefing animations depicting the activities of all three spacewalks.

Commander Shane Kimbrough disconnected cables from PMA-3 while still attached to Tranquility during a spacewalk on Friday. That work allowed ground controllers to use the Canadarm2 robotic arm to remotely grapple and remove PMA-3 from Tranquility and attach it to Harmony.

The relocation readies the PMA-3 for the future installation of the new International Docking Adapter-3 (IDA-3) set to be delivered on a future cargo mission. The IDA-3 will accommodate commercial crew vehicle dockings and provide the pressurized interface between the station and the adapter.

Thursday’s spacewalk will see Kimbrough and Peggy Whitson complete the PMA-3 attachment work on the Harmony’s space-facing port. The duo will also install computer relay boxes containing software upgrades to enable future commercial crew vehicle dockings at the International Space Station.
