A spacewalk deliberate Tuesday to restore a defective antenna on the International Space Station was postponed indefinitely, NASA stated, citing a “debris notification” it acquired for the orbiting analysis laboratory.
Two US astronauts had been scheduled to enterprise outdoors the house station at 7:10 a.m. Eastern time (1210 GMT) to start their work after NASA officers encountered particles from a Russian anti-satellite missile check. Slightly greater threat than stated. Month.
But about 5 hours earlier than the outing started, NASA stated on Twitter that the spacewalk has been known as off in the meanwhile.
NASA acquired particles stories for the house station. Due to a scarcity of alternative to correctly assess the chance to astronauts, the groups have determined to delay the November 30 spacewalk till extra data is offered. https://t.co/HJCXFWBd3Y pic.twitter.com/swj5hqusSo

It was not clear how shut the particles got here to the house station orbiting about 402 km above Earth, or whether or not it was associated to a Russian missile check.
NASA TV had deliberate to supply stay protection of the 6-1/2-hour “extra activity,” or EVA, operation by astronauts Thomas Marshburn and Kayla Barron.
The outing would be the fifth spacewalk for Marshburn, 61, a medical physician and former flight surgeon with two earlier journeys to orbit, and Barron, 34, a US Navy submarine officer and nuclear engineer on his first spaceflight for NASA. The first spacewalk for The goal is to take away a defective S-band radio communications antenna meeting, now greater than 20 years previous, and place it as a brand new addition on the surface of the house station.
According to the plans, Marshburn was to work with Baron whereas deployed to the top of a robotic arm operated from contained in the station by German astronaut Mathias Maurer of the European Space Agency, with the assistance of NASA crew mate Raja Chari.
The 4 arrived on the house station on November 11 in a SpaceX Crew Dragon capsule launched from the Kennedy Space Center in Cape Canaveral, Florida, becoming a member of two Russian astronauts and a NASA astronaut already on the orbit checkpoint.
Four days later, an anti-satellite missile check carried out by Russia with out warning generated a particles discipline in low-Earth orbit, and all seven crew members took refuge of their docked spacecraft, in order that Allowing a fast escape till the fast hazard has handed. NASA.
The cloud of residual particles from the detonated satellite tv for pc has since disintegrated, in line with Dana Weigel, NASA’s deputy supervisor of the International Space Station (ISS) program. But NASA has calculated that the remaining fragments proceed to pose a “slightly elevated” background threat to the complete house station, and a 7% greater threat of spacewalkers’ fits than earlier than Russia’s missile check, Weigel stated Monday. instructed reporters. ,
Although NASA has not but totally decided the extra hazards posed by the greater than 1,700 massive fragments, it’s monitoring across the station’s orbit, a 7% higher threat to astronauts than beforehand noticed within the “natural environment”. The falls have gone “well” of volatility, Weigel stated. Still, mission managers canceled a number of minor upkeep duties into account for Tuesday’s spacewalk, Weigel stated.
