The agenda for Expedition 70’s crew on Monday, October 23, prioritized readiness for upcoming spacewalks. Two cosmonauts from Russia’s space agency Roscosmos are slated to leave the station on Wednesday, October 25, while two NASA astronauts are preparing for their inaugural spacewalk scheduled for the following week.

Roscosmos Cosmonaut Extravehicular Endeavor

Flight Engineers Oleg Kononenko and Nikolai Chub plan to exit the Poisk module of the International Space Station at 2:10 p.m. Eastern Daylight Time on Wednesday. Their mission objectives include the installation of communication systems, the deployment of a nanosatellite, and an inspection of the auxiliary radiator that previously suffered a coolant leak. Earlier today, both engineers focused on readying the equipment they will require during their seven-hour journey, including the addition of lighting and video recording systems to the helmets of their Orlan suits.

NASA Astronauts Prepare for Upcoming Extravehicular Activity

NASA astronauts Jasmin Moghbeli and Loral O’Hara are diligently preparing for their first spacewalk, scheduled for next Monday at 8:05 a.m. The pair will depart the station to dismantle the Radio Frequency Group—a specialized electronics box—and to replace the bearing components within a solar array’s rotary joint. Their preparations today primarily involved procedural reviews and will escalate in complexity over the course of this week. Later in the evening, they participated in a conference call with ground teams, alongside JAXA (Japan Aerospace Exploration Agency) Flight Engineer Satoshi Furukawa and ESA (European Space Agency) Commander Andreas Mogensen.

Ongoing Station Maintenance and Scientific Research

Last month, researchers completed the final harvest of Arabidopsis plants as part of the Plant Habitat-03 study. This experiment aims to understand how successive plant generations might inherit adaptations in the demanding environment of microgravity. Today, Commander Mogensen devoted time to organize the facility and prepare Seed Bags for their impending return to Earth. Simultaneously, Furukawa managed the replacement of a filtration unit in a wastewater treatment system.

While the majority of station inhabitants were engrossed in preparations and procedural briefings for the forthcoming extravehicular activities, Roscosmos Flight Engineer Konstantin Borisov finalized maintenance operations and executed an experiment designed to analyze the nocturnal luminosity of Earth’s atmosphere in the near-ultraviolet spectrum.

interesting stuff, especially the research on plants. Never thought bout how plants would adapt in space.

The amount of prep that goes into a spacewalk is mind-blowing. Seven hours in space, but probably months of prep.

Can’t even manage my household plants and they’re doing agriculture in space. Puts things in perspective huh.

Always amazed by the science stuff they do up there. A wastewater treatment system in space, that’s next level.

What’s the deal with the Earth’s nocturnal glow? Never heard of it, but now I’m curious. Sounds trippy.
