The fully staffed International Space Station stepped up its life science research today studying a host of space phenomena. Two cosmonauts are also preparing for the 202nd spacewalk at the station late next week.
Flight Engineers Peggy Whitson and Jack Fischer checked out a variety of rodent research gear today. Whitson is getting a biology facility ready for a new experiment to be delivered next week on the SpaceX Dragon. Fischer looked at mice to help researchers determine the effectiveness of a new drug that may slow or reverse muscle and bone loss in space.
The next spacewalk is targeted for Aug. 17. Commander Fyodor Yurchikhin and Flight Engineer Sergey Ryazanskiy are reviewing their external tasks and work areas for a spacewalk expected to last a little over six hours. They’ll perform science and maintenance tasks and deploy tiny satellites during their orbital excursion.
From leg muscle scans to observing materials burning at high temperatures, the Expedition 52 crew continued researching what happens when you live in space. The space residents also upgraded electronics gear and installed new science racks.
Astronauts Randy Bresnik and Paolo Nespoli are barely a week into their 4-1/2 month long mission and are already exploring what space is doing to their bodies. The astronauts took ultrasound scans of their legs today to assess the changes their leg muscles and tendons are undergoing. The data will later be compared to the condition of their muscles before and after their spaceflight mission.
Jack Fischer of NASA installed new electronics gear in a science rack to speed up the communications rate at which data is uploaded and downloaded from the research facility. Station veteran Peggy Whitson swapped out samples exposed to high temperatures inside a specialized furnace. She later installed a pair of NanoRacks research platforms in the Kibo laboratory module. The commercial science devices will support upcoming experiments being delivered on the next SpaceX Dragon mission.
The crew today researched ways to alleviate headaches and reverse bone loss in space to improve mission performance. Meanwhile, the station’s three newest residents also checked out station emergency gear and systems.
Common ailments that afflict people on Earth such as headaches also affect astronauts in space impacting their mission activities. Astronauts Paolo Nespoli and Randy Bresnik are jotting down their experiences this week to help doctors understand space headaches. Observations may reduce their effects and improve performance during spaceflight and on Earth.
NASA astronauts Jack Fischer and Peggy Whitson are studying a new drug for its potential to slow or reverse bone loss in space. They looked at bones in mice today to help determine the efficacy of the new drug. The lack of gravity causes osteoporosis-like symptoms weakening bones in space possibly impacting crews returning to Earth and experiencing gravity for the first time in months.
Cosmonaut Sergey Ryazanskiy joined his crewmates Nespoli and Bresnik this afternoon familiarizing themselves with the station’s emergency equipment. The new trio explored their new home in space taking note of safety gear locations and escape paths.
Expedition 52 is now up to full speed with six crew members. The latest trio from the United States, Italy and Russia arrived Friday afternoon beginning a 4-1/2 month mission in space.
The new crew is familiarizing itself with International Space Station systems and getting used to life 250 miles above Earth’s surface. NASA astronaut Randy Bresnik is starting his second space mission and spent time on Tuesday replacing networking hardware in the Japanese Experiment Module.
Astronaut Paolo Nespoli of the European Space Agency is on his third spaceflight. Nespoli took part in the Sarcolab-3 study using the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module. The data collected for Sarcolab-3 will be used to assess microgravity’s impact on muscle loss in astronauts, focusing specifically on the calf muscle in the leg.
Cosmonaut Sergey Ryazanskiy begins his second mission aboard the station as a flight engineer. He last visited the orbital complex in 2013 with his Expedition 37-38 crewmates. Ryazanskiy conducted routine maintenance across the station’s Russian segment and assisted Nespoli during the Sarcolab-3 experiment session.
