First all-women spacewalk canceled over lack of medium-sized spacesuits
NASA’s plan to make a little space history with the first all-woman spacewalk has hit a snag: The right size spacesuit isn’t ready.

美國宇航局的計劃,在人類太空史上邁出一小步,第一次全女性太空行走遇到了一個障礙:合適的尺寸的太空服還沒有準備好。



The mission had originally planned for Koch, a former US Army aviator, to wear a large-size torso for her spacewalk with McClain, an aerospace engineer.

這次太空行走的任務最初計劃由美國陸軍前飛行員科赫穿著大號宇航內衣與航空工程師麥克萊恩一起完成。

The ISS only has one medium-sized hard upper spacesuit torso prepared for extra-vehicular activity (EVA), with the other acting as a spare. A NASA spokesperson told Quartz the station has two large torsos and one extra-large torso ready, plus a spare extra-large torso. Neither of the spares can be configured in time for the EVA planned for four days from now.

國際空間站只有一個中型的宇航硬殼內衣用于艙外活動,另一個作為備用。美國宇航局發言人告訴石英財經網。 國際空間站有兩件大號和一件加大號的宇航內衣,還有一件加大號的備用內衣。這兩件備用內衣都不能及時在四天內重新調整好尺寸用于艙外活動。

“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,” NASA spokesperson Brandi Dean told Quartz in an email. “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.”

“我們盡力預測每個宇航員需要的航天服尺寸,根據他們在地面上訓練時穿的宇航服的大小,在某些情況下,宇航員是身著不同尺碼的太空服進行訓練的, NASA發言人布蘭迪·迪恩在一封電子郵件中告訴石英財經網。“然而,當宇航員在軌道上時,他們的尺寸需求可能會根據微重力條件下身體發生的變化而變化,仍需指出沒有哪個訓練環境能夠完全模擬!”



An all-women spacewalk will have to wait, but McClain is scheduled for to head out the airlock again on April 8 alongside Canadian astronaut David Saint-Jacques.

第一次女性太空行走尚未成功,但麥克萊恩被安排在4月8日再次與加拿大宇航員大衛·圣雅克一起進行艙外行走。
