NASA's moon rocket is back on the launch pad ahead of the planned launch date of Nov. 14, but forecasters are keeping a close eye on the weather forecast.

Nov. 4 (UPI) -- NASA is making another run at launching the Artemis I spacecraft on its maiden voyage to the moon, rolling the $4.1 billion rocket back onto the launch pad Thursday at Kennedy Space Center after months of delays pushed the liftoff to Nov. 14.
The launch is scheduled a week from Monday at 12:07 a.m., but NASA was keeping an eye on a low-pressure system in the Caribbean that threatened to bring heavy rain and strong winds to the area in the coming days.

The agency still has about 10 days for a contingency plan if conditions worsen, although the rocket is built to withstand moderately strong weather.
Mission controllers considered the storm to be a very low threat and expressed confidence in their decision to move forward.
"I think everyone feels really good about the launch," said Jim Free, associate administrator of the Exploration Systems Development Mission Directorate at NASA headquarters in Washington. "If we weren't confident, we wouldn't roll out. If we weren't confident, we wouldn't start the countdown when we do so. We're confident moving forward."
Late Thursday night, crews began moving the nearly 3,000-ton Space Launch System rocket and Orion spacecraft from the Vehicle Assembly Building back to launch pad 39B, some 4 miles away. By Friday morning, the rocket was in place.
The unmanned Artemis I mission has been dogged by several malfunctions, including fuel leaks and engine-related problems before NASA put the ship back into storage in late September just days before Hurricane Ian came ashore.
The first launch attempt on Aug. 29 was canceled due to a fuel leak and a bad sensor on one of the main engines. The next launch attempt on Sept. 3 was scrubbed due to a fuel leak that NASA has since repaired.
The agency next eyed a launch window between Sept. 19 and Oct. 4, but the approaching storm nixed that plan as well.

NASA chose to wait out the next launch window that expired on Halloween, taking the extra time to conduct routine maintenance and ensure all flight systems are working as expected.
The upcoming Nov. 12-27 launch window, like previous timeframes, is determined by the cycles of the Earth and moon as they need to be in just the right tandem for the encounter.
The Artemis I mission sets the stage for astronauts to return to the lunar surface for the first time since 1972, which will happen sometime in 2025 or 2026 as part of the Artemis 3 mission.
For now, Artemis I will fly more than a half-million miles to the moon and back over 42 days while testing the limits of the Orion crew module and its Space Launch System rockets.
Next year, astronauts will be aboard the Artemis 2 capsule, which will circle the Earth and moon in the mission's first manned test flight.
