NASA Gears Up for Dual Spacewalks and Microgravity Research

NASA astronauts are preparing for spacewalks on June 24 and July 2 to maintain and upgrade the International Space Station.

Spacewalk preparations and biotechnology research kept the Expedition 71 and NASA’s Boeing Crew Flight Test crews busy aboard the International Space Station (ISS) on Tuesday, June 18.

The next spacewalk at the orbital outpost will be June 24 when NASA astronauts Tracy C. Dyson and Mike Barratt will remove faulty radio hardware and swab station surfaces for microorganisms as was initially planned. A second spacewalk to remove and replace a gyroscope assembly, relocate an antenna, and prepare for future Alpha Magnetic Spectrometer upgrades is planned for July 2. NASA will determine assignments for the July 2nd spacewalk once the June 24 activities are complete.
