On the eve of the launch of the Artemis mission, NASA readies its mega-moon rocket for liftoff

NASA's massive next-generation rocket is planned to launch on its first test flight on Monday, marking the start of the agency's Artemis moon-to-Mars program fifty years after the Apollo program's termination. The Kennedy Space Center in Florida spent the final full day prior to the launch on preparations.

NASA officials confirmed on Sunday that all systems seemed to be "go" for launch, and weather forecasts anticipated an 80% chance of favorable conditions for the start of Monday's two-hour launch window, commencing at 8:33 a.m. EDT (12:33 GMT) and reducing to 60% by the end.

The senior NASA test director for the historic Artemis I mission, Jeff Spaulding, commented, "From a vehicle standpoint, everything to date looks good." "We are ecstatic, since the vehicle is now complete and looks great."

Although lightning rods were damaged at the launch site during a storm on Saturday, Spaulding stated that "nothing on the ground systems gives us cause for concern." NASA said that neither the spacecraft nor the launch facilities sustained any damage.

The Space Launch System (SLS) rocket is scheduled to propel an unmanned Orion capsule around the moon and back on a six-week test mission before the 2024 launch of humans. The SLS-Orion combination is the centerpiece of NASA's successor to the Apollo lunar program of the 1960s and 1970s.

NASA hopes to return astronauts to the moon, including the first woman to set foot on the lunar surface, as early as 2025 if these two missions are successful, although many observers believe this schedule is likely to be delayed by a few years. The final humans to walk on the moon were the two-person descent team of Apollo 17 in 1972, after ten astronauts on five previous missions beginning with Apollo 11 in 1969.

NASA officials predict that it will take at least until the late 2030s to achieve the Artemis program's objective of creating a permanent lunar colony as a stepping stone for even more ambitious astronaut missions to Mars.

SLS has been in development for about a decade, during which time there have been multiple years of delays and cost hikes. Nevertheless, the Artemis program has also generated tens of thousands of jobs and billions of dollars in economic activity through its primary contractors Boeing (NYSE:BA) Co for SLS and Lockheed Martin Corp (NYSE:LMT) for Orion.

During a launch-eve news conference, Spaulding informed reporters that he did not anticipate any technical hurdles to the countdown. NASA officials were concerned on Sunday about a potential, if slight, helium leak in launch pad equipment, but he did not foresee any technical obstacles to the launch.

Remember that this is a test flight, NASA administrator Bill Nelson told Reuters during an interview that was abruptly cut short by a phone call from the U.S. Vice President Kamala Harris, who will be in Florida to see the rocket launch in person.

"She is ecstatic!" Nelson stated after the call ended.
