Two astronauts go on spacewalk outside the ISS

Two astronauts of NASA would be walking outside the International Space Station (ISS), in space on 16th May. Their spacewalk would last up to 6.5 hours and their Extra-Vehicular Activity (EVA) would be featured online.

The flight engineers of the expedition 55 namely- Ricky Arnold and Drew Feustel would go out of the space station at near about 8.10 a.m. EDT (1210 GMT) via the Quest airlock. The astronauts would reportedly put on the spacesuits and get prepared by around 6:30 a.m. EDT (1030 GMT) when the space agency would offer live coverage to the viewers.

The astronauts reportedly target at upgrading the “cooling system hardware” of the space station and installing the latest communications equipment. Initially, they would be moving the Pump Flow Control Subassembly (PFCS) from a secondary equipment platform to a region that could be reached by the Special Purpose Dexterous Manipulator, or “Dextre.” The Dextre is a robot with two arms outside the space station. The duo is even tasked to move a damaged subassembly to the secondary equipment platform. After the completion of the spacewalk, the Flight Controllers on the Earth would make use of the Dextre’s robotic hand and the Canadarm2 robotic arm for installing a new “cooling system subassembly.”

If time permits further, the astronauts would replace the camera system at the Destiny Laboratory and also upgrade the “communication receiver” for the upcoming commercial crew spacecraft such as the Boeing’s CST-100 Starliner and the SpaceX’s Crew Dragon. Jordan Lindsay, the officer leading the spacewalk of 16th May said in a previous briefing that they have got a “camera R&R plan as well as a commercial box that will be part of the EVA as well.”

Both the astronauts would be taking another spacewalk again on 14th June Thursday for installing cameras and brackets that would be guiding the commercial crew spacecraft to the landing ports. The cameras would even help to transmit and receive wireless information from the experiments in the Columbus laboratory in Europe and the Kibo laboratory in Japan.

The duo had earlier taken another spacewalk of 6 hours on 29th March for installing antennas for wireless communication. They reportedly also fixed a failed cooling system. The spacewalk on 16th May would be the ISS’s 210th spacewalk since the year 1998.

The initial spacewalk was taken on 18th March in the year 1965 and had been conducted by Alexei Leonov. The spacewalk reportedly lasted for around ten minutes. The next spacewalk was taken on 3rd June in the year 1965 by the American astronaut Ed White. It reportedly lasted for around twenty-three minutes.
