International Space Station: September 2017



The Expedition 53 crew worked on a variety of astronomy gear today that looks at meteors in Earth orbit and harmful radiation from deep space. The crew also explored how microgravity affects human bones and muscles.


Expedition 53 is gearing up for three maintenance spacewalks set to take place in October over a period of two weeks. Meanwhile, the six-member crew continued researching today how their long-term missions in space affect their bodies.


Today - Node 1 Communication: Ground teams utilized the video conferencing system to patch Space to Ground channel 2 (S/G2) to an SSC in Node 1, and asked the crew to confirm that S/G2 voice was audible in Node 1.


SpaceX's Dragon cargo craft splashed down in the Pacific Ocean at approximately 10:14 a.m. EDT, southwest of Long Beach, California, and the recovery process is underway, marking the end of the company's twelfth contracted cargo resupply mission to the International Space Station for NASA.

Today - Lighting Effects: The crew completed a visual assessment test in the Crew Quarters (CQs) by setting the light to the correct mode, turning all other light sources in the CQ off, and performing one Numerical Verification Test and one Color Discrimination Test.


Today's science tasks included an inspection on an advanced microscope and readying a magnetic field experiment. The crew also worked on a failed electrical device that was robotically transferred to the Kibo laboratory module in early August.


A new set of Expedition 53 crew members arrived at the Baikonur Cosmodrome launch site today ahead of their Sept. 12 liftoff to the International Space Station.


Today - 50 Soyuz (50S) Undock: 50S, with Peggy Whitson, Jack Fischer, and Fyodor Yurchikin onboard, undocked Saturday at 4:58 PM CDT and landed in Kazakhstan at 8:22 PM CDT. The ISS will be in 3-crew operations until the arrival of 52S on September 13.


Record-breaking NASA astronaut Peggy Whitson and her Expedition 52 crewmates, Flight Engineer Jack Fischer of NASA and Commander Fyodor Yurchikhin of the Russian space agency Roscosmos, are scheduled to depart the International Space Station and return to Earth Saturday, Sept. 2.
