The first all-female spacewalk was scheduled to happen on Friday, March 29.

Astronauts Anne McClain and Christina Hammock Koch were scheduled to perform the historic spacewalk – a routine mission to replace batteries outside the International Space Station (ISS). On the ground, lead flight director Mary Lawrence and spacewalk flight controller Jackie Kagey were slated to support McClain and Koch at mission control.

As INSIDER’s Dave Mosher reported, a NASA spokesperson previously said the spacewalk was “was not orchestrated to be this way.”

But what was once lauded as a happy accident is now leaving people befuddled.

On Monday, NASA announced a change of plans due to a lack of proper equipment. Specifically, both McClain and Koch can't go on the mission because there is only one size medium space suit available.

"McClain learned during her first spacewalk that a medium-size hard upper torso - essentially the shirt of the spacesuit - fits her best," NASA said in a statement. "Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it."

Instead, McClain, who had been training in a different size space suit, will be replaced by astronaut Nick Hague. At this time, NASA has not planned another all-female spacewalk.

Online, people were dismayed by the news.

Many felt that it just didn't make sense.

Some people felt that it was pretty fitting for 2019.

And yes, there were jokes.

On Tuesday, NASA attempted to quell concerns that had arisen. The changes, although disappointing to many, had the astronauts' safety in mind, the tweet said.

"We've seen your tweets about spacesuit availability for Friday's spacewalk," the tweet said. "To clarify, we have more than 1 medium size spacesuit torso aboard, but to stay on schedule with Space Station upgrades, it's safer & faster to change spacewalker assignments than reconfigure spacesuits."
