Cosmonauts complete first serial cosmodrome to upgrade station batteries



Two NASA astronauts have been working to replace batteries outside the International Space Station, completing the first of a series of planned space shuttles to modernize the orbital lab's power system.

The expedition of 61 pilots Christina Koch and Andrew Morgan on Sunday (October 6th) operated in a vacuum of space for 7 hours and 1 minute. Their extra-ventricular activity (EVA, or space passage) began at 7:39 a.m. EDT (1139 GMT) and ended at 2:40 p.m. EDT (1840 GMT).

Continuing the process that began with the initial set of battery replacements in January 2017 Koch and Morgan went to the far left, or to the port, toward the space station's support farm. to work on some of the old collateral electricity storage.

The space station is powered by eight large wings of the solar array, four on each side of the farm. The arrays supply electricity to the station's systems when they are under sunlight and charge the bank with four large batteries mounted near their base as the station shades into Earth.

Koch and Morgan replaced two old nickel-hydrogen batteries with two new lithium-ion batteries that were delivered to the space station aboard of the Japanese H-II-8 (HTV-8) vehicle September 28. Each of the more powerful lithium-ion batteries can hold two nickel-hydrogen batteries.

The space duo first took out one of the old batteries and then, carefully passing it back and forth to each other, assigned a massive block to an empty socket near an open pallet containing new batteries.

"I have a battery," Koch said, holding a nickel-hydrogen battery.

"You have a battery," Morgan confirmed.

Each battery is about half the size of a refrigerator, or 40 inches. 37 inches long, 19 inches wide (101 by 94 by 48 centimeters). Old nickel-hydrogen batteries weigh 365 pounds. (165 kilograms) each. Lithium-ion replacements weigh 428 pounds. (194 kg). Although the weight in the microgravity environment does not cause concern, the mass of the batteries is still a factor of inertia.

The first old battery was an "open dock" on an open pallet for about two hours at EVA.

NASA astronaut Jessica Mayr, working from inside the station, then used the robot arm Canadarm2 to rearrange the pallet so that the first replacement battery was within reach of the space shuttle. Koch and Morgan then repositioned the new lithium-ion battery in the empty slot they had just opened on the built-in equipment in the raft port of Port 6 (P6).

The first new battery was locked in place approximately 50 minutes after the old battery had been stacked on the pallet.

The following astronauts removed the adapter board from the pallet and mounted it on the rafters to integrate the newly installed lithium-ion battery into the station's electrical system. Working ahead of schedule, Koch and Morgan were released from a control assignment in X&J to remove another nickel-hydrogen battery and install it on an adapter plate, where it would be stored for a long time.

Finally, Koch and Morgan moved another of the new lithium-ion batteries from the pallet to the farm, where they installed it in an empty slot released by the second nickel-hydrogen unit. They also repositioned the battery maneuvering tools and loosened torque on the bolts that provided two nickel-hydrogen batteries as they prepared for the next spaceport.

"It was a beautiful day," Koch said, returning to the space station quest . air lock . "We look forward to the rest of the series."

<p>  Four more batteries Spacecraft replacement is currently planned. Koh and Morgan will reunite with EVA scheduled for Friday (October 11), followed by space walks Morgan and Meir on October 16 and Meir and Koch on October 21, the last ever EVA female EV. The final scheduled space trip in the series will be held on October 25 by Commander Meir and the expedition of Luca Parmitano from the European Space Agency (ESA). </p><div><script async src=

Regular EVA unrelated to battery replacement scheduled for October 31 Russian cosmonauts Alexander Skvortsov and Oleg Skrypochka. Another five American space walks are planned for Morgan and Parmitano in November to repair the cosmic rays Alpha Magnetic Spectrometer (AMS).

EVA on Sunday was Koch and Morgan's second space. . Morgan, who as an EV2 wore a suit with no identifiers, generally lasted 13 hours and 33 minutes, covering his two EVAs.

It was the 219th cosmodrome dedicated to the International Space Station since its collateral in 1998. The astronauts and astronauts spent 1374 hours and 27 minutes, or 57.3 days, working outside the orbital complex.
