NASA Television will provide live coverage of the undocking and landing.

The homebound crew is packing gear in their Soyuz vehicle and training to use the Lower Body Negative Pressure suit which gets their bodies ready for the return Earth’s gravity. In the midst of Soyuz departure preparations, the crew is also continuing the International Space Station’s mission of advanced microgravity science to benefit life on Earth and in space.

There was more Rodent Research work on Friday as scientists study mice to understand the effects of weightlessness on muscles and bones. The crew is also participating in the Fine Motor Skills experiment which looks at how astronauts interact with touch-based technologies and spacecraft instrumentation.

Spacesuit and Life Science Work

The Expedition 43 crew
ISS043E270899 (05/30/2015) — The Expedition 43 crew gathers aboard the International Space Station to affix their mission patch to the vehicle.

Spacesuit maintenance took up most of the day for a pair of astronauts. Crew members also explored the long-term effects of microgravity on the brain and vision.

Commander Terry Virts joined Italian astronaut Samantha Cristoforetti in the Quest joint airlock to swap out a fan pump separator inside a U.S. spacesuit. The duo are checking the device after earlier maintenance work revealed it wasn’t functioning properly.

Before that work began, Cristoforetti relocated the Protein Crystallization Research Facility in Japan’s Kibo lab module. Virts wrapped up his workday with some maintenance in a science freezer ensuring it stays cold enough to store biological samples for later analysis.

One-Year crew members Mikhail Kornienko and Scott Kelly joined fellow Soyuz crewmate Gennady Padalka for ongoing Fluid Shifts experiment work. The trio received assistance from ground operators as they collected vision data using a variety of medical tools. Watch an interview with Mike Stenger, one of the co-principal investigators of the Fluid Shifts experiment.

The six-member Expedition 43 crew conducted a variety of advanced microgravity science and performed spacesuit maintenance. U.S. astronauts Terry Virts and Scott Kelly also commemorated 50 years of operations in Houston’s Mission Control Center.

The orbital lab’s inhabitants explored a complex set of subjects in space including physics, biology and crew health. Flight Engineer Gennady Padalka studied plasma crystals which could benefit future spacecraft design. Italian astronaut Samantha Cristoforetti continued her work with the Rodent Research experiment that could potentially lead to new drugs to treat diseases on Earth.

One-Year crew member Mikhail Kornienko was back at work on the Fluid Shifts study partnering with Kelly and Padalka. The trio took measurements as part of an investigation to better understand how microgravity impacts fluid pressure in the head, changes in vision and eye structures.

On June 3, 1965, Mission Control Center in Houston began operations when Gemini IV lifted off for a four-day mission with astronauts James McDivitt and Ed White. America’s first spacewalk also took place during that mission when White floated out of the spacecraft attached to a 25-foot umbilical line and tether.

The Permanent Multipurpose Module (PMM) was successfully relocated from the Unity module to the Tranquility module at 9:08 a.m. EDT Wednesday.

The PMM was robotically relocated from the Earth-facing port of the Unity module on the International Space Station to the forward port of the Tranquility module in the next step to reconfigure the complex for the future arrival of U.S. commercial crew vehicles. Robotic flight controllers at Mission Control, Houston, working in tandem with the Mobile Servicing System (MSS) Operations Center at the Canadian Space Agency’s headquarters in St. Hubert, Quebec, Canada, used the Canadarm2 robotic arm to maneuver the 11-ton module a short distance to its new location. Expedition 43 Commander Terry Virts and Flight Engineer Scott Kelly of NASA supervised the commanding of the bolting of the PMM to Tranquility. The PMM’s hatch will be reopened tomorrow.

The operation opened the Earth-facing port of Unity as another berthing location for U.S. commercial cargo vehicles. Future U.S. commercial crew vehicles will arrive at the space-facing and forward ports of the Harmony module, which will continue its transformation later this year when a pair of International Docking Adapters (IDAs) will be delivered on the seventh and ninth NASA-contracted SpaceX cargo resupply missions. The IDAs will be attached to Pressurized Mating Adapters 2 and 3, enabling the station to host up to two U.S. commercial cargo and two U.S. commercial crew vehicles at any given time.

 

Watch NASA TV at 8 a.m. EDT for Robotics Move

The Permanent Multipurpose Module

The International Space Station’s Permanent Multipurpose Module (PMM) was detached from a berthing mechanism on the Earth-facing port of the Unity module at 5:50 a.m. EDT by robotics flight controllers at Mission Control, Houston, working in tandem with Canadian Space Agency (CSA) engineers at the robotics support center located at CSA Headquarters in St. Hubert, Quebec, Canada. Used as a supply depot for the orbital laboratory, the 11-ton PMM is being maneuvered to an installation position at the forward port of the Tranquility module through the use of the station’s robotic arm, Canadarm2. NASA Television will provide coverage of the final steps of the installation and provide a replay of pertinent video from the start of the operation beginning at 8 a.m. EDT.

Once it is in the proper position, Expedition 43 Commander Terry Virts and Flight Engineer Scott Kelly of NASA will oversee the module’s final attachment to Tranquility. Virts and Kelly will reopen the hatch to the PMM at its new location tomorrow.

This move will clear the Unity port for its use as a second berthing location for U.S. commercial cargo spacecraft; the Earth-facing port on Harmony is currently used as the home port for U.S. cargo craft. The relocation of the PMM is the next step in the reconfiguration of the station that will allow U.S. commercial crew vehicles to dock to new docking ports on the forward and space-facing side of the Harmony module. That will provide a total of four ports for U.S. vehicles arriving at the orbital outpost.
