Earlier this week, the Worldwide Area Station was pressured to regulate its orbit to keep away from an encroaching industrial satellite tv for pc. The thing is probably going certainly one of many Earth-observing satellites which might be falling into and aligning with the area station’s orbital path, in response to consultants.
On Monday, the Progress 83 resupply ship that’s docked to the area station fired its engines for simply over six minutes, barely elevating the orbit of the ISS with a view to keep away from an approaching satellite tv for pc, NASA wrote in a weblog put up. The area company didn’t establish the item, besides to say that it was an “Earth statement satellite tv for pc.”
Nonetheless, there may be hypothesis that the satellite tv for pc in query could also be Argentina’s Nusat-17, certainly one of 10 industrial Earth statement satellites type the Aleph-1 constellation operated by Satellogic. Jonathan McDowell, an astrophysicist on the Harvard-Smithsonian Middle for Astrophysics, wrote on Twitter that the orbits of the Satellogic constellation has been step by step decaying and the satellites at the moment are crossing the orbit of the ISS.
The newest ISS maneuver factors to a bigger concern of the rising variety of satellites, each defunct and operational, and particles that pose a risk to orbiting spacecraft. Greater than 27,000 items of orbital particles are at the moment being tracked by the Division of Protection’s world Area Surveillance Community, with a lot of smaller items additionally floating round undetected.

In December 2022, the ISS performed an analogous maneuver to keep away from a collision with a Russian Fregat-SB higher stage fragment that threatened to return inside lower than 1 / 4 mile of the area station. The truth is, the area station has needed to perform 32 collision avoidance maneuvers since 1999. These orbital swerves haven’t impacted the astronauts on board the ISS to this point. NASA acknowledged that the newest maneuver gained’t impression the approaching Crew-5 departure from the area station.
The 4 astronauts of the Crew-6 mission arrived on the ISS on March 3, whereas Crew-5 astronauts are set to return residence aboard the docked SpaceX Endurance spacecraft as quickly as March 9. Nonetheless, Cosmonauts Sergey Prokopyev and Dmitry Petelin, and NASA astronaut Frank Rubio, will keep aboard the ISS till September.
