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.
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.

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.
Two astronauts are getting the Quest airlock and their equipment ready for a Friday morning spacewalk. The cosmonauts continued their human research program today exploring the various affects of living in space.
Spacewalkers Shane Kimbrough and Thomas Pesquet will exit the Quest airlock Friday at 8 a.m. EDT to begin setting up the International Space Station for future commercial crew missions. The duo will work outside for about 6.5 hours on the first of three spacewalks scheduled to take place over the next two weeks.
Friday’s major tasks include disconnecting cables from the Pressurized Mating Adapter-3 ahead of its relocation from the Tranquility module to the Harmony module on Sunday. The latching end of the Special Purpose Dexterous Manipulator will also be lubricated and computer relay boxes with commercial crew software upgrades will be replaced. NASA TV will cover the spacewalk activities live beginning Friday at 6:30 a.m.
Cosmonauts Andrey Borisenko and Oleg Novitskiy collected their blood, saliva and urine samples today for a metabolism study and an immunity experiment. Researchers will analyze these samples to learn how microgravity affects humans and provide countermeasures to keep crew members healthy.
The astronauts took a break from spacewalk preparations today and checked out an expandable module and worked on science freezers. The crew also continued its human research program exploring space nutrition and the effects of microgravity on metabolism and the immune system.
Thomas Pesquet opened the hatches to the Bigelow Expandable Activity Module (BEAM) today for a status check. The European Space Agency astronaut sampled BEAM’s air and surfaces for microbes and installed impact sensors. He also used a digital camera with a fish-eye lens to capture 360-degree imagery of the inside of BEAM.
Veteran NASA astronaut Peggy Whitson serviced three science freezers ensuring biological samples can be preserved for return on an upcoming SpaceX Dragon mission. She also brushed up on robotics skills necessary for Friday’s spacewalk.
Cosmonaut Oleg Novitskiy logged his meals again today before collecting saliva samples for an immunity study. Flight Engineer Andrey Borisenko researched how living in space long term affects metabolism and a crew member’s psychophysiological state.

Three astronauts are preparing for a Friday morning spacewalk to upgrade and maintain the International Space Station’s external systems. The three cosmonauts stayed focused today on their set of Russian space experiments and life support work.
Friday’s spacewalk will see Kimbrough and Pesquet begin setting up the station for future commercial crew missions. They will prepare the Pressurized Mating Adapter-3 for removal from the Tranquility module to the Harmony module. The astronauts will also replace computer relay boxes with software upgrades for future dockings of commercial crew vehicles.
In the midst of the spacewalk work today, Pesquet received a call from the French President Francois Hollande who toured an observatory with school children outside Lyon, France. Kimbrough and Whitson answered questions submitted by social media fans on Facebook Live Tuesday morning
Cosmonauts Oleg Novitskiy and Andrey Borisenko documented what they ate for breakfast and lunch today for a pair of nutrition studies. The experiments are researching how diet affects a crew member’s metabolism and bone structure while living in space. Flight Engineer Sergey Ryzhikov spent the day checking Russian life support gear and sampling drinking water.

The Expedition 50 crew is gearing up for three spacewalks over two weeks to continue the external maintenance at the International Space Station. Also, the SpaceX Dragon is returning to port today after completing a month-long stay at the station.
The two spacewalkers will spend 6.5 hours disconnecting cables from the Pressurized Mating Adapter-3 (PMA-3), lubricating the tip of the Canadarm2, inspecting a radiator and replacing cameras. Computer relay boxes will also be replaced. The new hardware contains software upgrades for future dockings of commercial crew vehicles.
Friday’s cable work on the PMA-3 will prepare it for its relocation from the Tranquility module to the Harmony module on March 30. The relocation readies the PMA-3 for the future installation of the new International Docking Adapter-3 set to be delivered on a future cargo mission.
The SpaceX Dragon is heading to its port today in southern California after a successful splashdown in the Pacific Ocean Sunday morning. NASA support personnel will retrieve the numerous research samples stowed in Dragon’s cargo hold and deliver them to scientists for analysis. The results of the advanced space science may improve disease therapies and injury treatments on Earth.
SpaceX’s Dragon cargo craft splashed down in the Pacific Ocean at 10:46 a.m. EDT, about 200 miles southwest of Long Beach, California, marking the end of the company’s tenth contracted cargo resupply mission to the International Space Station for NASA.
Expedition 50 astronauts Thomas Pesquet of ESA (European Space Agency) and Shane Kimbrough of NASA released the SpaceX Dragon cargo spacecraft from the International Space Station’s robotic arm right on schedule, at 5:11 a.m.
A variety of technological and biological studies are returning in Dragon. The Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.
Samples from the Tissue Regeneration-Bone Defect study, a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studied what prevents vertebrates such as rodents and humans from re-growing lost bone and tissue, and how microgravity conditions affect the process. Results will provide a new understanding of the biological reasons behind a human’s inability to grow a lost limb at the wound site, and could lead to new treatment options for the more than 30 percent of the patient population who do not respond to current options for chronic non-healing wounds.
The Dragon spacecraft launched Feb. 19 on a SpaceX Falcon 9 rocket from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida, and arrived at the station Feb. 23.
