Station commander Peggy Whitson and flight engineer Jack Fischer, both with NASA, will partner for the spacewalk, which is expected to last two hours, the U.S. space agency said.

A pair of astronauts will venture outside the International Space Station on Tuesday for an emergency spacewalk to replace a failed computer, one of two that control major U.S. systems aboard the orbiting outpost, NASA said on Sunday.
NASA’s last emergency spacewalk took place in December 2015 when two U.S. astronauts left the station to release the brakes on a robot arm’s mobile transporter.

The station, owned and operated by 15 nations, flies about 250 miles (400 km) above Earth and orbits the planet about every 90 minutes.

She was really active in promoting women in science, and equality in science.”Dove works with undergraduate students on their planetary science research and continues to reach out to young girls to encourage the pursuit of STEM careers.
The award is given to scientists early in their careers who embody Nieber’s work ethic and outreach.
Dove looks at how particles of dust stick together in microgravity, hoping to shed light on how planets formed.
She was a strong supporter of women in science and someone Dove admired.

NASA is preparing to conduct a spacewalk on Tuesday, May 23, to replace a computer component mounted on the International Space Station that failed Saturday morning.
The spacewalk to replace the data relay box is expected to take about two hours.
The multiplexer-demultiplexer (MDM) is one of two redundant data relay boxes used to control the solar array systems, radiators, cooling loops, and other hardware aboard the station.
Whitson assembled and tested a spare data relay box on Sunday morning, and she reported that the new box is functional and ready to be installed as a replacement.
NASA added an additional task for Fischer to install a pair of wireless communication antennas while Whitson replaces the box.
