NASA's return to the Moon is delayed yet again, after engineers failed to plug a hydrogen leak on the launch pad Saturday.
NASA's SLS may be a new rocket, but its engines, which once powered the Space Shuttle, are anything but.
They may have to compete for the limited resources on the lunar surface.
The two-hour launch window starts at 2:17 p.m. ET (6:17 p.m. UTC) on September 3. The rocket's Monday launch was scrubbed due to temperature sensor problems.
NASA is under tremendous pressure to launch its new megarocket—and it shows.
An engine that refused to cool down led to today’s scrub, delaying the much-anticipated inaugural launch of NASA’s SLS.
The SLS megarocket was supposed to blast off Monday at 8:33 a.m. ET, but a pesky engine has complicated plans.
The inaugural launch of the SLS megarocket is the first step in returning humans to the lunar surface later this decade.
The inaugural launch of SLS is scheduled for Monday, August 29, and everything seems to be going according to plan.
The space agency is preparing to return humans to the lunar surface for the first time in more than 50 years.
The SLS rocket is set to travel to the launch pad Tuesday evening. Its inaugural launch will represent the first mission in the Artemis lunar program.
The maiden voyage of SLS is set for November 16, kicking off NASA's return to the Moon and setting the stage for crewed missions.
A previous plan called for a pruned list of 18 astronauts, but that's no longer the case, according to NASA's chief spaceman.
The local tourism office says more than 100,000 spectators are likely to hunker down near Kennedy Space Center in Florida.
The launch of the SLS megarocket will kick off a series of missions in which NASA seeks to return humans to the Moon.
The much-anticipated first launch of the Space Launch System could happen as early as late August.
A problematic hydrogen leak and incomplete countdown rehearsal means a fifth SLS wet dress rehearsal is a distinct possibility.
The dress rehearsal for Artemis 1 starts on Saturday, with propellant loading expected on Monday.
An Inspector General report blamed NASA's commercial partner Bechtel for its "poor performance."
The upcoming test of the mega Moon rocket marks the fourth attempt following a series of failed launch rehearsals in April.
