NASA’s 2028 moon landing may be delayed because of lack of space suits, watchdog report warns NASA needs new space suits to land astronauts on the moon by 2028, but development is behind and in danger of slipping further, according to a report from the agency’s Office of Inspector General

Now on @sciam.bsky.social: Delays to lunar landing systems aren't the only things that could dash NASA's hopes of putting U.S. bootprints back on the moon by 2028. A lack of lunar spacesuits could push crewed landings to 2031 or later, a new report warns.
