The Artemis I rocket launched early Wednesday morning, the latest attempt to send an unmanned capsule near the moon after a series of postponements due to weather and mechanical issues.

NASA pushed back a takeoff scheduled for Monday after Hurricane Nicole made landfall about 85 miles south of Cape Canaveral, Florida.

The launch marks the first step in an ambitious plan to establish a long-term presence on the moon for scientific discovery and economic development. Eventually, the Artemis expedition could lead to the first crewed space trip to Mars, according to NASA.

NASA's Space Launch System (SLS) rocket with the Orion spacecraft attached rests on launch pad 39B as final preparations are made for the Artemis I mission at NASA's Kennedy Space Center on Nov. 15, 2022, in Cape Canaveral, Fla.

Technicians need to replace ethernet cable

NASA said the "red crew" team has fixed the hydrogen leak problem.

However, a radar on the range is not operational until technicians replace an ethernet cable, which NASA says will take about an hour.

The launch window opens at 1:04 a.m. and runs until 3:04 a.m.

Leak reported ahead of launch

NASA has reported a "small leak" ahead of the Artemis launch.

"Engineers have paused flowing liquid hydrogen into the core stage because of a small leak on a hydrogen valve inside of the mobile launcher," NASA said. "A team of personnel called a red crew is being assembled to go to the pad to make sure all of the connections and valves remain tight. The valve is located within the base of the mobile launcher."
