A pair of NASA astronauts aboard the International Space Station are embarking on a six-and-a-half-hour spacewalk today to upgrade and fix the orbiting outpost.
The astronauts on the International Space Station are getting some spring cleaning done Wednesday morning.
The goal of the NASA spacewalk is to upgrade the station's cooling system hardware, as well as installing new communications equipment that will be used for future docking of commercial care spacecraft.
Over the course of the hours-long excursion, astronauts Drew Feustel and Ricky Arnold, both veteran spacewalkers, will swap out a failed cooling component with a replacement on the station's port-side truss. The astronauts will move the Pump Flow Control Subassembly from a platform that houses spare parts to the Special Purpose Dexterous Manipulator-better known as a robotic arm-on the exterior of the station.
According to Jordan Lindsay, the lead officer for today's spacewalk, in a briefing on May 8th, "We have a camera R&R [rest and recuperation] plan as well as a comm box...that will be part of the EVA as well". Overall, it's the 210th space walk For ISS assembly, maintenance and upgrades since the complex was first launched back in 1998. It is Fuestel's eighth spacewalk and Arnold's fourth.
Feustel and Arnold arrived at the ISS on March 23 and are slated to return to Earth in October.
Meanwhile, the station's six-man crew is expecting a delivery.
As of the publishing of this article, there is plenty of time left during the mission so you'll be able to see the majority of the process if you tune in now.
