Preparations for the arrival of a visiting crew, the continued examine of how people adapt to the microgravity setting of house, the service of methods on board a docked cargo ship and the documentation of European landmarks from Earth orbit stored the seven astronauts and cosmonauts on the Worldwide House Station (ISS) busy this week (June 2 via June 6), the sixth week of Expedition 73.
Orbital statement
“I observed smoke over the Northern U.S. and Canada a number of days in the past, and it took me a short time to know what it was. From our perspective, it nearly appears to be like like a otherwise coloured cloud formation,” flight engineer Nichole Ayers, a NASA astronaut, wrote on X on June 3 after recognizing the smoke from wildfires in Canada that has precipitated evacuations in thee provinces and affected the air high quality throughout a number of U.S. states.
“The brown hue to the clouds and the truth that they overlapped the white clouds caught my eye. I have been attempting to seize it every day to assist in understanding the smoke motion. I hope everybody stays secure!” Ayers wrote.
Science standing
Among the many analysis that was carried out aboard the house station this week was:
Bio-Monitor — For 2 days this week, NASA astronaut Jonny Kim wore this Canadian instrument to evaluate if it could actually gather his well being information whereas being comfy to put on and never intrude together with his different actions.
Digital — Russian cosmonaut Alexey Zubritskiy, assisted by Sergey Ryzhikov, donned a pair of VR goggles as a part of a examine into the vestibular system’s skill in microgravity to visually monitor motion whereas additionally maintaining a way of steadiness.
Drain Mind 2.0 — Expedition 73 commander Takuya Onishi of JAXA (the Japan Aerospace Exploration Company) measured the blood circulation from his mind to his coronary heart utilizing electrodes from this fast screening device, which might assist forestall and diagnose blood clots whereas in house.
Elvis — Ayers labored with the Extant Life Volumetric Imaging System, a 3D microscope stored in JAXA’s Kino laboratory, which she used to look at deep-sea micro organism samples. The demo might result in utilizing the same system to establish potential infectious organisms in water provides each in house and on Earth.
Zubritskiy additionally spent a few days this week documenting Japanese European landmarks whereas fellow cosmonaut Kirill Peskov took photographs of the Volga River and Aral Sea to visually assess the aftermaths of each pure and human-caused disasters.
Station maintaining
The crew additionally devoted time to sustaining the house station’s methods, together with:
BEAM — Ayers and fellow NASA astronaut Anne McClain moved {hardware} into stowage aboard the Bigelow Expandable Exercise Module, which serves as a “float-in” closet for the station since being put in and inflated in 2016.
Spaceborne Laptop-2 — Kim changed a processor cartridge for this industrial off-the-shelf pc, which is being assessed for its skill to facilitate analysis evaluation with out the necessity for Earth-based assist.
PCBA — McClain up to date the firmware for the Transportable Medical Blood Analyzer, a handheld unit that’s used to shortly take a look at blood samples for quite a few analysis research carried out on the ISS.
AstroPi — Kim additionally relocated this computer-controlled digital camera from a window contained in the Unity module to a unique window contained in the European House Company’s (ESA) Columbus module. College students remotely use a pair of those cameras for engineering and science tasks.
Ryzhikov additionally cleaned out a heater fan and crammed an oxygen generator tank within the Progress MS-29 (90P) cargo spacecraft in addition to assisted Zubritskiy within the work to service a neutron radiation detector within the Russian phase of the house station.
Astronaut exercise

Along with the work detailed above, McClain labored on SoFIE-MIST.
“SoFIE-MIST stands for Stable Gas Ignition and Extinction–Materials Ignition and Suppression Check,” she wrote in a June 6 X submit. “MIST consists of a small-scale combustion wind tunnel, cylindrical gasoline pattern, an igniter, radiant heaters, and instrumentation. By various parameters like air circulation pace, oxygen focus, strain, and degree of exterior radiation, then viewing the resultant flame produced on the pattern, we are able to higher characterize early habits of fireplace. This helps us select higher supplies to be used in house, and it helps decide one of the best strategies of extinguishing fires in house.”
“This week, I modified out the gasoline samples and igniter for the subsequent science run.”
Making house for guests
The Expedition 73 crew’s actions this week additionally included making ready for the arrival of short-term guests: Axiom House’s fourth industrial mission to the Worldwide House Station is scheduled to reach aboard a SpaceX Dragon spacecraft on Wednesday (June 11), assuming an on-time launch the day prior.
Former NASA astronaut Peggy Whitson will lead the Ax-4 crew, which incorporates pilot Shubhanshu Shukla of India and mission specialists Sławosz Uznański-Wiśniewski of Poland (and ESA) and Tibor Kapu of Hungary.
The station crew reviewed the Ax-4 plan with mission managers on the bottom whereas McClain and Ayers, who’re assigned to supervise the Dragon’s method from contained in the station, went over the docking procedures. The 2 used a pc to evaluation the conditions they may encounter when the Dragon nears the orbiting complicated.
Onishi readied the pill computer systems that will likely be utilized by Whitson, Shukla, Uznański-Wiśniewski and Kapu throughout their two-week science analysis mission.
By the numbers
As of Friday (June 6), there are 7 folks aboard the Worldwide House Station: commander Takuya Onishi of JAXA, Anne McClain, Nichole Ayers and Jonny Kim of NASA and Kirill Peskov, Sergey Ryzhikov and Alexey Zubritsky of Roscosmos, all flight engineers.
There are two docked crew spacecraft: SpaceX’s Dragon “Endurance” connected to the ahead port of the Concord module, and Roscosmos’ Soyuz MS-27 connected to the Earth-facing port of the Prichal node.
There are additionally two docked cargo spacecraft: Rosocmos’ Progess MS-29 (90P) connected to the space-facing port of the Poisk module and Progress MS-30 (91P) connected to the aft port of the Zvezda service module.
As of Friday, the house station has been constantly crewed for 24 years, 7 months and 5 days.
