Nasa astronauts Christina Hammock Koch and Nick Hague, members of the International Space Station (ISS) expedition 59/60, react shortly before the launch onboard the Soyuz MS-12 spacecraft
Christina Koch will now perform tasks in space Friday with fellow American Nick Hague -- instead of Anne McClain as originally planned.
Had Koch and McClain done their spacewalk together, it would have been the first ever by two women astronauts.
Until now, male-only or mixed male-female teams had conducted spacewalk since the space station was assembled in 1998 -- 214 spacewalks until now.
Nasa astronaut Christina Hammock Koch, a member of the International Space Station (ISS) expedition 59/60, looks on as her spacesuit is tested prior to the launch onboard the Soyuz MS-12 spacecraft from the Russian-leased Baikonur cosmodrome in Kazakhstan.
McClain worked outside the station last week -- with Hague -- when she realized that a "medium"-sized upper half of her spacesuit fit her better.
"Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it," NASA explained.
The spacesuits aboard the ISS are in fact assemblies of several parts put together as best adapted to each astronaut's body, explained Brandi Dean, spokeswoman of the Johnson Space Center in Houston, Texas where American astronauts are based.
She said two upper parts in each of the three available spacesuit sizes are currently held at the ISS: medium, large and extra large.
"We do our best to anticipate the spacesuit sizes that each astronaut will need, based on the spacesuit size they wore in training on the ground, and in some cases astronauts train in multiple sizes.
"However, individuals' sizing needs may change when they are on orbit, in response to the changes living in microgravity can bring about in a body.
"In addition, no one training environment can fully simulate performing a spacewalk in microgravity, and an individual may find that their sizing preferences change in space."
NASA's Mars Helicopter has successfully completed a series of tests and is ready to take flight over the Red Planet, the US space agency said. "The next time we fly, we fly on Mars," MiMi Aung, Project Manager for Mars Helicopter at NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement.
Astronomers began speculating about these omnivorous "dark stars" in the 1700s, and since then indirect evidence has slowly accumulated.
NASA have made it clear they want astronauts back on the Moon in 2024, and now, they are zeroing in on the Red Planet -- the US space agency confirmed that it wants humans to reach Mars by 2033.
Sheikh Abdullah Bin Zayed Al Nahyan, Minister of Foreign Affairs and International Cooperation, commended the role played by Egypt in ensuring regional stability, noting that the current circumstances the region is passing through entail “cementing pan-Arab solidarity and cooperation to confront the besetting challenges.” The UAE’s top diplomat’s remarks came during his meeting on Sunday with Egyptian President Abdel Fattah El Sisi who reaffirmed his country’s support for the UAE during the critical stage the region is experiencing.
