The Expedition 75 crew aboard the International Space Station (ISS) continued preparations Thursday for a spacewalk scheduled for August 18, whereas additionally conducting experiments involving digital actuality and synthetic intelligence.
Nasa astronauts Anil Menon and Sophie Adenot of the European Area Company are scheduled to enterprise exterior the station subsequent Tuesday to interchange a failed high-speed space-to-ground antenna. The spacewalk is predicted to final about six-and-a-half hours.
Menon and Adenot will start the spacewalk after switching their spacesuits to battery energy at 8.35 am EDT (6.05 pm IST). The astronauts will exit by way of the Quest airlock and journey to the Z1 truss section above the Unity module, the place the antenna is put in.
The astronauts will first take away the present antenna and place it on an exterior stowage platform. They’ll then retrieve a spare antenna from the platform and set up it on the Z1 truss earlier than securing the outdated gear.
NASA astronauts Jack Hathaway and station commander Jessica Meir will help the spacewalk from contained in the station. They’ll assist Menon and Adenot placed on and take away their spacesuits and function the Canadarm2 robotic arm.
Menon might be positioned on the robotic arm’s latching finish effector throughout a part of the operation, whereas Adenot will stay tethered to the station’s truss and help with the antenna alternative.
Spacesuits and emergency procedures checked
Spacewalk preparations have been underway all through the week. On Thursday, Menon and Hathaway checked the performance of Menon’s spacesuit, together with refilling its tanks and liquid-cooling air flow garment with water.

Meir and Adenot additionally reviewed the specialised instruments wanted to make {the electrical} and knowledge connections between the alternative antenna and the Z1 truss.
The crew held discussions with mission controllers and robotics specialists to evaluate security procedures, technical directions and Canadarm2 manoeuvres forward of the spacewalk.
On Wednesday, the crew additionally performed emergency response coaching. All seven Expedition 75 astronauts and cosmonauts reviewed their roles within the occasion of a stress leak, chemical leak, or hearth.
The crew used tablets to evaluate emergency procedures and coordinated with mission controllers on Earth to simulate the actions required to guard themselves and the station.

Crew conducts VR and AI experiments
Whereas the Nasa and ESA astronauts targeted on the spacewalk, the station’s Roscosmos crew continued scientific experiments utilizing superior expertise.
Flight engineers Pyotr Dubrov and Anna Kikina took turns carrying digital actuality headsets and responding to computer-generated visible stimuli. The experiment is designed to review how the human sense of steadiness and route adapts to microgravity.
The cosmonauts additionally carried out different station upkeep and statement actions. Dubrov performed an automatic Earth pictures session, whereas Kikina and Andrey Fedyaev continued work involving synthetic intelligence instruments supposed to enhance crew effectivity throughout future house missions.
The crew additionally carried out photographic inspections of the home windows within the Zvezda service module, Nauka science module, and Poisk mini-research module.

With the August 18 spacewalk approaching, the Expedition 75 crew is predicted to proceed reviewing procedures, checking gear and coordinating with floor groups to make sure the antenna alternative may be carried out safely.
