The astronauts on the International Space Station are getting some spring cleaning done Wednesday morning.

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.

While out in space, the astronauts are expected to conduct a number of improvements and upgrades to hardware and technology on the station.

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 first step of this process is to move a componentcalled the Pump FLow COntrol subassembly froma space parts platform over to an area that is within reach of the Special Purpose Dexterous Manipulator - also known as Dextre - which is a two-armed robot upside the station.

In addition to giving the cooling system a boost, the astronauts are expected to add a new camera and a communications receiver to the Destiny Laboratory. It is Fuestel's eighth spacewalk and Arnold's fourth.

Meanwhile, the station's six-man crew is expecting a delivery. With SpaceX quickly becoming a force to be reckoned with, the ability to better support their ships and Boeing's ships will be a welcome change for everyone involved.
