The primary focus of the Expedition 70 team aboard the International Space Station (ISS) on Friday, October 6, was on preparations for upcoming extravehicular activities. NASA administrators provided an overview at the week’s end of the planned activities, which include the astronauts departing from the orbital facility to gather microbial samples and to carry out maintenance on various pieces of equipment.

Flight Engineer Loral O’Hara from NASA and Station Commander Andreas Mogensen from ESA are slated to leave the ISS on October 12 for an extravehicular activity expected to last six hours. They will employ specialized instruments to swab the external surfaces of the space station to collect microbial specimens for scientific analysis. The samples will undergo examination to ascertain the species of microorganisms that can withstand the conditions of outer space.

The animated briefing concerning the extravehicular activity scheduled for October 12 elaborates that astronauts Loral O’Hara of NASA and Andy Mogensen of ESA will depart from the Quest airlock of the space station. They are tasked with collecting microbial samples from the station’s exterior for subsequent analysis. In addition, they will replace a high-definition camera situated on the port truss and perform other upkeep tasks in anticipation of future extravehicular activities. Credit: NASA

Joining O’Hara and Mogensen on Friday were astronauts Jasmin Moghbeli of NASA and Satoshi Furukawa of the Japan Aerospace Exploration Agency (JAXA). Together, the four astronauts liaised with ground-based experts and went over the procedures for the imminent extravehicular activity. The team also reviewed the robotic operations that will be integral to the microbe-collecting mission. During the extravehicular activity, Moghbeli and Furukawa are assigned to operate the Canadarm2 robotic arm, oversee the spacewalking astronauts, and assist them in donning and doffing their spacesuits.

An animated briefing for the extravehicular activity planned for October 20 outlines that NASA astronauts Loral O’Hara and Jasmin Moghbeli will engage in a roughly six-and-a-half-hour spacewalk. They are responsible for disassembling a malfunctioning electronics compartment, known as a Radio Frequency Group, from a communications antenna located on the starboard truss. They will also replace one among twelve Trundle Bearing Assemblies on the Solar Alpha Rotary Joint situated on the port truss. Credit: NASA

NASA administrators featured the forthcoming extravehicular activities during a NASA TV broadcast on Friday, and also spotlighted a second extravehicular activity slated for October 20. During this, O’Hara and Moghbeli will commit to another excursion into the vacuum of space to remove defective radio communication equipment and to set up new components for the solar arrays.

On the Russian side of the ISS, the trio of cosmonauts representing Roscosmos focused on scientific research and orbital facility maintenance. Veteran Flight Engineer Oleg Kononenko engaged in the setup of Earth-monitoring equipment during the morning hours and devoted the remainder of his day to electronics and communications setup. Nikolai Chub performed cleaning tasks on the ventilation systems in the Zvezda service module and also conducted studies on piloting techniques for future spacecraft. Konstantin Borisov took photographs of terrestrial forests to document both natural and human-induced alterations and concluded his workday by inspecting the docking port elements on Zvezda.

Are they actually gonna find any microbes in space? Would be groundbreaking if they do, I reckon.

So the Canadarm2 is still kicking, huh? I remember when that tech was first introduced, seems like its still very relevant.
