The Space Shuttle Discovery is ready for its final flight to the International Space Station Thursday, say NASA officials.
Debate is still underway to determine whether the space shuttle Atlantis should get one more flight or be sent straight to a museum.
NASA has cleared the space shuttle Atlantis for its final launch Friday. The space shuttle program is set to be retired this year.
The space shuttle launch was early Monday from the Kennedy Space Center. The 13-day mission will help prepare the International Space Station for life after the shuttle program ends later this year.
Sensors failed to signal fuel valve’s status. But further tests may allow officials to “relax” a rule.
Unless the valves are in working order, Discovery will remain Earthbound. Previous shuttle missions have encountered problems with the components, too.
The comparatively low-key mission, scheduled to launch at 1:36 a.m. Tuesday, marks the winding down of the space shuttle program.
