WASHINGTON — It is just about enterprise as ordinary on the Worldwide House Station as NASA adjusts its present actions and future plans to Russia’s determination to interchange a broken Soyuz spacecraft docked there.
NASA astronaut Nicole Mann and JAXA astronaut Koichi Wakata will conduct a spacewalk Jan. 20 to put in a mounting bracket for a brand new photo voltaic array that shall be delivered to the station on a future cargo mission. The spacewalk, the primary by any astronaut, is scheduled to final from six and a half to seven hours.
The spacewalk is an indication that actions on the house station are persevering with largely unaffected by injury to the Soyuz MS-22 spacecraft that docked there on Dec. 14 that Roscosmos and NASA have attributed to a micrometeor hit. The accident broken the spacecraft’s radiator and brought on a coolant leak.
The 2 companies introduced Jan. 11 that that they had concluded the spacecraft couldn’t safely return to Earth, with its three-man crew consisting of Roscosmos astronauts Sergey Prokopyev and Dmitry Petlin and NASA astronaut Frank Rubio. As a substitute, a brand new Soyuz spacecraft, Soyuz MS-23, shall be despatched to the station uncrewed to interchange Soyuz MS-22, which is able to return to Earth, additionally uncrewed.
On January 18, astronauts transferred a custom-fitted Rubio seat liner from Soyuz MS-22 to the Crew Dragon spacecraft docked on the station. Within the occasion of an emergency requiring crew evacuation, Rubio would return aboard Crew Dragon whereas Prokopyev and Petelin departed on Soyuz MS-22.
“We expect that can take a few of the warmth load off the Soyuz spacecraft and can assist us with the general scenario,” Dina Kontella, operations integration supervisor for the Worldwide House Station Program at NASA, stated throughout a Jan. 17 briefing in regards to the upcoming spacewalk. .
Transferring Rubio’s seat to Crew Dragon is barely a short lived measure. After the Soyuz MS-23 arrives on the station, its seat liner, together with the Prokopyev and Petelin seats, shall be transferred to the Soyuz MS-23. Soyuz MS-23 is scheduled to launch on February 20, docking with the station two days later.
The launch of Soyuz MS-23 will barely delay the launch of Crew-6 Crew Dragon. In a press convention on Jan. 11, NASA stated it’s going to take as much as two weeks to revise the schedule for each that mission and different flights to the station within the close to future. Contella stated on the spacewalk briefing that Crew-6 was scheduled to launch in mid-to-late February, with Crew-5 Crew Dragon returning a couple of days later.
The Crew-6 mission consists of astronaut Sultan Al Neyadi of the United Arab Emirates. The Mohammed bin Rashid House Heart within the United Arab Emirates introduced on January 19 that the Crew-6 mission was scheduled to launch no later than February 26, a few week later than beforehand deliberate.
Kontella stated Crew-6 shall be adopted by the Dragon cargo mission, CRS-27, in March. This can in flip be adopted by a Cygnus cargo spacecraft, NG-19, although it didn’t say when it could launch. NG-19 would be the final Cygnus spacecraft to be launched on the present model of the Antares rocket as Northrop Grumman is working with Firefly Aerospace on a brand new first stage of the car.
The choice to interchange Soyuz MS-22 with Soyuz MS-23 implies that Prokopyev, Petelin and Rubio will prolong their keep on the Worldwide House Station. The three have been initially scheduled to return to Earth in March, however will keep for as much as six extra months. Kontella stated they may doubtless return in late September, a few yr after they arrived. “We’re wanting on the actual timing of that, however at this level, that will be when the automobile is deliberate to go house.”
The Soyuz coolant leak occurred whereas Prokopyev and Petlin have been getting ready for the spacewalk, which was canceled because of this and has not but been rescheduled. “Our Russian colleagues are engaged on their future plans for spacewalks at this level,” she stated.
