2 astronauts performing spacewalk Wednesday morning: Watch live

Two astronauts will conduct a spacewalk outside the International Space Station on Wednesday morning, and you can watch it live.

The astronauts from NASA and the European Space Agency are going to step outside the lab on Wednesday. For a roughly 6.5-hour spacewalk, or extravehicular activity.

You can watch it live at Space.com or via NASA TV. The coverage starts at 7:30 a.m. The time is 1130 GMT.

Major milestones and how they work are what spacewalks are about.

NASA officials wrote in a spacewalk preview earlier this month that the two spacewalkers will install hoses on a Radiator Beam Valve Module that routes ammonia through the station's heat-rejecting radiators to keep systems at the proper temperature.

The crew members will install a power and data cable on the Columbus module and replace an external camera on the station.

This will be the second EVA for the station crew. The space lab was ready for the addition of an upgraded solar array after seven hours of work by NASA astronauts.
