Astronauts are taking a spacewalk today to upgrade a space station science module. Watch it live!

Two NASA astronauts will upgrade a crucial International Space Station (opens in new tab) science module in orbit during a spacewalk today (Jan. 27), and you can watch the whole thing live.

The spacewalk is expected to start at 7 a.m. EST (1130 GMT) if the final suit-up procedures go to plan, and to last about six and a half hours, according to NASA (opens in new tab). Coverage will start at 5:30 a.m. EST (1000 GMT), and you can watch it live here at (opens in new tab), courtesy of NASA TV. 

Floating in space will be flight engineers Michael Hopkins (on his third spacewalk, wearing red stripes on his spacesuit as he is lead spacewalker) and Victor Glover (on his first).

During today's spacewalk (opens in new tab) the astronauts will focus on finishing essential cable and antenna setup for a new research platform, Bartolomeo, outside the European Space Agency's Columbus module. Bartolomeo will host up to 12 research experiments simultaneously in fields such as astrophysics, robotics and material physics.

Other spacewalking tasks will include configuring a high-speed Ka-band terminal that will allow the science module to communicate independently with European ground stations, and removing a grapple fixture bracket to prepare for future power system upgrades, NASA added.

At least three more spacewalks are on tap for the Expedition 64 crew, including one with the same astronauts on Monday (Feb. 1), when Glover and Hopkins will install the final lithium-ion battery adapter plate to wrap up four years of crucial battery upgrades on the space station (opens in new tab), which replaced older and less powerful nickel-hydrogen batteries.

Other tasks on Monday's spacewalk include removing another grapple fixture bracket, installing two cameras, and replacing components for the Japanese robotic arm's camera system outside the Japanese Aerospace Exploration Agency (JAXA) Kibo module.

A third spacewalk (date to be announced) will see Glover and NASA astronaut Kate Rubins prepare the space station power system for a power boost using new solar arrays (opens in new tab). The fourth extravehicular activity — also not yet scheduled — will have Rubins and JAXA astronaut Soichi Noguchi do more station upgrades, which NASA will outline during a future media briefing.
