NASA Space Station On-Orbit Status 29 March 2017 - Spacewalk on Tap.

Expedition 50 Flight Engineer Peggy Whitson is set to go on her eighth spacewalk Thursday morning and surpass astronaut Suni Williams' record for the most spacewalks by a female astronaut.

Whitson's last spacewalk was on Jan. 6 with Commander Shane Kimbrough when she hooked up new lithium-ion batteries and inspected the Alpha Magnetic Spectrometer.

Thursday's spacewalk will see Whitson and Kimbrough finish cable connections at the Pressurized Mating Adapter-3 just recently attached to the Harmony module's space-facing port. The PMA-3 relocation gets the station ready for the new International Docking Adapter-3 set to be delivered on a future SpaceX Dragon cargo mission.

European Space Agency astronaut Thomas Pesquet, who conducted last week's spacewalk with Kimbrough, will assist the duo in and out of their spacesuits and monitor the activities from inside the station. The spacewalkers are scheduled to exit the Quest airlock Thursday at 8 a.m. EST for 6.5 hours of station maintenance work. NASA TV will cover all the spacewalk activities beginning at 6:30 a.m.

On-Orbit Status Report

Dose Tracker Data Entry: The crew performed their weekly Dose Tracker data logging, responding to a questionnaire which asks if crew members have used medications since the last entry, what prompted them to use the medication, how well it worked, how frequently they repeated doses, and if the medication caused side effects. The Dose Tracker investigation uses an iPad app to collect information on members' medication use during their missions. Results help determine whether medicines act differently on humans in space than they do on Earth.

European Space Agency (ESA) Active Dosimeter Swap: The crew swapped the currently worn Mobile Unit (MU) with a charged MU and initiated the data download to the ESA Active Dosimeter Personal Stowage Device (PSD). The European Crew Personal Active Dosimeter is an active device worn by European ISS crewmembers in orbit to measure the radiation exposure. This device, coupled with other dosimeters in ESA's Columbus Laboratory, provides radiation dosage information that can be used to support risk assessment and dose management. The future goal is to enable the verification of radiation monitoring systems for future medical monitoring of crewmembers in space.

U.S. Extravehicular Activity (EVA) #41 Preparations: In preparation for tomorrow's planned EVA, today the crew completed the following:

Configured tools required for the EVA.
Verified that batteries are installed in Pistol Grip Tools (PGTs) and EVA cameras.
Prepared the Equipment Lock, EMUs and ancillary hardware to support EVA prep activities.
Procedures review including detailed timeline, briefing package, tool config summary and planned get-ahead tasks.
Following the procedures review the crew participated in a conference with ground teams to discuss questions or concerns. The crew is scheduled to egress at 7:10AM CDT.
