But NASA has had to [reshuffle](https://www.nasa.gov/press-release/nasa-updates-spacewalk-assignments-announces-final-preview-briefing) the personnel partially because of a lack of correctly sized spacesuits, the agency said Tuesday. “Mission managers decided to adjust the assignments, due in part to spacesuit availability on the station,” NASA said in a statement. McClain, who went on a spacewalk on March 22, discovered that a medium-size spacesuit fits her best. Koch needs the same size spacesuit, but there’s only one currently available on the station. Koch will continue to do the March 29 spacewalk, which is the second in a series of three spacewalks scheduled for March and April, but will be joined by astronaut Nick Hague instead of McClain. Earlier this month, when the [first all-women spacewalk](http://time.com/5546676/nasa-first-all-female-spacewalk/) was announced, NASA spokesperson Stephanie Schierholz noted that the history-making walk was coincidental and “not orchestrated to be this way.” > [](https://twitter.com/NASA/status/1110291521490829319) The decision to put off the first all-female spacewalk nevertheless triggered backlash on Twitter, with some critics blaming poor planning and saying it reflects the need for more diversity in the aerospace industry. > [](https://twitter.com/heroinebook/status/1110313517599449088) > [](https://twitter.com/cmclymer/status/1110366311840993283) NASA selected its [first female astronauts](https://www.nasa.gov/feature/with-every-first-in-space-new-dreams-are-launched) in 1978, and women now account for about 34% of its astronauts. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/5558667/nasa-spacewalk-all-women-delay/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/5558667/nasa-spacewalk-all-women-delay/"},"headline":"NASA Nixes the Upcoming All-Women Spacewalk","datePublished":"2019-03-26T08:04:31.000Z","dateModified":"2026-02-23T23:08:28.251Z","description":"NASA said the last-minute change was \"in part\" due to available spacesuit sizes","url":"https://time.com/5558667/nasa-spacewalk-all-women-delay/","keywords":["Space","onetime","overnight"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd49d436c8c5c80ac/6989474ddb298753e12620d5/christina-koch-nasa.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Hillary Leung","jobTitle":null,"url":"https://time.com/author/hillary-leung/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltd49d436c8c5c80ac/6989474ddb298753e12620d5/christina-koch-nasa.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"christina-koch-nasa.jpg","caption":"Christina Koch NASA","creditText":"Mikhail Japaridze—TASS/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/space/","name":"Space"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/5558667/nasa-spacewalk-all-women-delay/","name":"NASA Nixes the Upcoming All-Women Spacewalk"}}]}] ```
