Spacewalk Preps Underway Amidst Space Research

The Expedition 61 crew is gearing up for the first three spacewalks of 2020 set for this month. Meanwhile, the International Space Station is bustling with an array of microgravity research activities today.

NASA astronauts Jessica Meir and Christina Koch will conduct the first two spacewalks scheduled for Jan. 15 and Jan. 20. The duo will finish replacing older nickel-hydrogen batteries with new lithium-ion batteries on the station’s Port-6 truss structure. They spent Wednesday reviewing spacewalk procedures and inspecting spacesuit tethers.

The next spacewalk would be Jan. 25 following the successful battery replacements. NASA astronaut Andrew Morgan and Commander Luca Parmitano of ESA (European Space Agency) will finish the repair work they started in November on the station’s cosmic particle detector, the Alpha Magnetic Spectrometer.

In the midst of the spacewalk preparations, the lab residents kept up the ongoing space science to improve life for humans on and off Earth.

Morgan began the day installing botany research gear inside Japan’s Cell Biology Experiment Facility before transferring resupply racks to the Cygnus space freighter. Parmitano conducted a vision test then cleaned up Rodent Research hardware that housed mice that were returned to Earth aboard the SpaceX Dragon cargo craft.

Cosmonauts Alexander Skvortsov and Oleg Skripochka split their time on Russian science and maintenance tasks. The duo partnered together for a study exploring piloting methods under a variety of gravity conditions. Skvortsov then measured the station’s radiation environment as Skripochka replaced fuel bottles for combustion research.

Dragon Splashes Down in Pacific Returning Science and Cargo

Dragon Splashes Down in Pacific Returning Science and Cargo

The SpaceX Dragon separates from the International Space Station

The SpaceX Dragon spacecraft splashed down at 10:42 a.m. in the Pacific Ocean about 271 miles southwest of Long Beach, California, marking the end of the company’s 19th contracted cargo resupply mission to the International Space Station for NASA.

A key component being returned aboard Dragon is a faulty battery charge-discharge unit (BCDU), which failed to activate following the Oct. 11 installation of new lithium-ion batteries on the space station’s truss. The BCDU was removed and replaced during a spacewalk Oct. 18 by Expedition 61 flight engineers Christina Koch and Jessica Meir of NASA. The unit are being returned to teams on Earth for an evaluation and repair.

Dragon launched on the SpaceX Falcon 9 rocket Dec. 5 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida, and arrived at the station two days later with almost 3,400 pounds of science, supplies and cargo.
