Expedition 59 Aircraft engineers Nick Hague and Anne McClain of NASA have completed their walk at 14:40. EDT. During a six-hour 39-minute space walk, two NASA astronauts successfully replaced nickel-hydrogen batteries with newer, more powerful lithium-ion batteries for an energy channel on one pair of solar cell stations.
The astronauts could also perform several tasks, including removing waste outside the station, ensuring that they stay on the Solar Array Blanket Box and taking a snapshot of an unmanaged sack bag and an air curtain heat exchanger that opens and closes for space walks.
These new batteries provide better performance for low-mass operations and lower volume of nickel-hydrogen batteries.
Next week, McClain and aviation engineer Christina Koch predicted that on 29 March they would fly in the outer space to work on another series of battery exchanges on another power channel in the same area of the station. It would be the first space march with space aliens.
The Hague and David Saint-Jacques of the Canadian Space Agency are scheduled to launch a third space exhibition on April 8 to set up jumps between the Unity module and the carrier S0 in the middle of the spine of the station.
This work will create a redundant power path to a robotic arm manufactured in Canada, known as Canadarm2. They will also install cables that provide wider coverage of wireless communications outside the orbital complex as well as for enhanced wired computer network performance.
The crew members of the space station made 214 space transitions in support of the assembly and maintenance of the orbital laboratory. It was the first walk for McClain and The Hague. The amphibians now spent a total of 55 days, 21 hours and 39 minutes working outside the station.

NASA distributes its first female walk into space
Washington DC (SPX) March 21, 2019
NASA will send 39-year-old astronauts Anne McClain and 40-year-old Christina Koch to 29th NASA's first strollers to space.
The all-female spacecraft will be supported by a female land crew: Mary Lawrence will be the flying director, and Jackie Kagey will be running a space flight controller at NASA's Johnson Space Center in Houston.
This is an appropriate milestone for the Month of Women's History, although NASA says the time frame is random.
McClain and Koch were part of the NA … read more
