On Monday Moscow Standard Time, the International Space Station (ISS) Flight Control team was notified of indications of a satellite breakup that may create sufficient debris to pose a conjunction threat to the station. NASA Administrator Bill Nelson released the following statement about the incident:
“Earlier today, due to the debris generated by the destructive Russian Anti-Satellite (ASAT) test, ISS astronauts and cosmonauts undertook emergency procedures for safety.
“Like Secretary Blinken, I’m outraged by this irresponsible and destabilizing action. With its long and storied history in human spaceflight, it is unthinkable that Russia would endanger not only the American and international partner astronauts on the ISS, but also their own cosmonauts. Their actions are reckless and dangerous, threatening as well the Chinese space station and the taikonauts on board.
“All nations have a responsibility to prevent the purposeful creation of space debris from ASATs and to foster a safe, sustainable space environment.
“NASA will continue monitoring the debris in the coming days and beyond to ensure the safety of our crew in orbit.”
The crew was awakened and directed to close the hatches to radial modules on the station, including Columbus, Kibo, the Permanent Multipurpose Module, Bigelow Expandable Activity Module, and Quest Joint Airlock. Hatches between the U.S. and Russian segments remain open.
An additional precautionary measure of sheltering the crew was executed for two passes through or near the vicinity of the debris cloud. The crew members made their way into their spacecraft shortly before 2 a.m. EST and remained there until about 4 a.m. The space station is passing through or near the cloud every 90 minutes, but the need to shelter for only the second and third passes of the event was based on a risk assessment made by the debris office and ballistics specialists at NASA’s Johnson Space Center in Houston.

Space Command statement:
Russia tested a direct-ascent anti-satellite (DA-ASAT) missile on Nov. 15, 2021, Moscow Standard Time, that struck a Russian satellite [COSMOS 1408] and created a debris field in low-Earth orbit. The test so far has generated more than 1,500 pieces of trackable orbital debris and will likely generate hundreds of thousands of pieces of smaller orbital debris.
“Russia has demonstrated a deliberate disregard for the security, safety, stability, and long-term sustainability of the space domain for all nations,” said U.S. Army Gen. James Dickinson, U.S. Space Command commander. “The debris created by Russia's DA-ASAT will continue to pose a threat to activities in outer space for years to come, putting satellites and space missions at risk, as well as forcing more collision avoidance maneuvers. Space activities underpin our way of life and this kind of behavior is simply irresponsible.”
USSPACECOM's initial assessment is that the debris will remain in orbit for years and potentially for decades, posing a significant risk to the crew on the International Space Station and other human spaceflight activities, as well as multiple countries' satellites. USSPACECOM continues to monitor the trajectory of the debris and will work to ensure all space-faring nations have the information necessary to safeguard their on-orbit activities if impacted by the debris cloud, a service the United States provides to the world, to include Russia and China.
“Russia is developing and deploying capabilities to actively deny access to and use of space by the United States and its allies and partners,” Dickinson added. “Russia's tests of direct-ascent anti-satellite weapons clearly demonstrate that Russia continues to pursue counterspace weapon systems that undermine strategic stability and pose a threat to all nations.”
