Impact of space station spin requires research, official says

MOSCOW (AP) — Space engineers will analyze whether or not a glitch that brought about the International Space Station to spin out of its regular orientation may have impacted any of its programs, a Russian space official mentioned Wednesday.

Sergei Krikalev, the director of crewed space applications on the Russian space company Roscosmos, emphasised that final week’s incident didn’t inflict any observable injury to the space station, however he mentioned that consultants would wish to check its potential implications.

“It appears there is no damage,” Krikalev mentioned in an interview broadcast by Russian state tv. “But it’s up to specialists to assess how we have stressed the station and what the consequences are.”


Thrusters on Russia’s Nauka laboratory module fired shortly after the module arrived on the International Space Station on Thursday, making the orbiting outpost slowly spin about one-and-a-half revolutions. Russia’s mission controllers fired thrusters on one other Russian module and a Russian cargo ship connected to the space station to cease rotation after which push the station again to its regular position.

Both U.S. and Russian space officers mentioned the station’s seven-person crew wasn’t in peril throughout the incident.

The station must be correctly aligned to get the utmost energy from photo voltaic panels and to take care of communications with space help groups again on Earth. The space station’s communications with floor controllers blipped out twice for a couple of minutes on Thursday.

NASA mentioned in a tweet Tuesday that the station was 45 levels out of alignment when Nauka’s thrusters had been nonetheless firing and loss of management was mentioned with the crew.

“Further analysis showed total attitude change before regaining normal attitude control was (tilde)540 degrees,” NASA mentioned, emphasizing that the “station is in good shape and operating normally.”

Roscosmos’ Krikalev, a veteran of six space missions who spent a complete of 803 days in orbit, famous Wednesday that firing orientation engines created a dynamic load on the station’s parts, making a radical evaluation of whether or not some of them might be overstressed essential.

“The station is a rather delicate structure, and both the Russian and the U.S. segments are built as light as possible,” he mentioned. “An additional load stresses the drivers of solar batteries and the frames they are mounted on. Specialists will analyze the consequences, and it is too early to talk about how serious it was, but it was an unforeseen situation that requires a detailed study.”

Krikalev mentioned Nauka’s engines fired as a result of a glitch within the management system mistakenly assumed that the lab module hadn’t but docked on the station and activated the thrusters to drag it away.

The launch of the 22-ton (20-metric-ton) module has been repeatedly delayed by technical issues. It was initially scheduled to go up in 2007, however funding issues pushed the launch again, and in 2013 consultants discovered contamination in its gasoline system, leading to an extended and dear alternative. Other Nauka programs additionally underwent modernization or repairs.

Nauka is the primary new compartment for the Russian section of the International Space Station since 2010, providing extra space for scientific experiments and room for the crew. Russian crew members must conduct as much as 11 spacewalks starting in early September to organize it for operation.

The space station is at present operated by NASA astronauts Mark Vande Hei, Shane Kimbrough and Megan McArthur; Oleg Novitsky and Pyotr Dubrov of Roscosmos; Japan Aerospace Exploration Agency astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet.

In 1998, Russia launched the station’s first compartment, Zarya, which was adopted in 2000 by one other large piece, Zvezda, and three smaller modules within the following years. The final of them, Rassvet, arrived on the station in 2010.
