Eventually, the Artemis expedition could lead to the first crewed space trip to Mars, according to NASA.Nov 15, 9:46 PM EST Leak reported ahead of launchNASA 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.”-ABC News’ Gio BenitezNov 15, 9:28 PM EST How to watch the Artemis launchThe Artemis launch will take place early Wednesday morning, unless NASA postpones the takeoff due to weather or other concerns.If Artemis is declared ready, a two-hour window will open at 1:04 a.m. ET. If needed, the back-up windows are Saturday, Nov. 19, and Friday, Nov. 25.NASA will broadcast the launch on NASA TV.Nov 15, 9:24 PM EST Weather 90% favorable for launchThe weather is currently at 90% favorable for the Artemis launch early Wednesday morning, according to NASA’s Exploration Ground Systems.Nov 15, 9:02 PM EST Artemis mission aims to send astronauts to the moonThe Artemis launch on Wednesday kicks off a yearslong expedition that aims to put astronauts on the moon and enable a future trip to Mars.The Artemis expedition includes four missions, each of which will cost roughly $4.1 billion. In all, the project will cost up to $93 billion by 2025, according to an audit from the NASA Office of the Inspector General.If Artemis I is successful, Artemis II will take four astronauts near the moon in 2024. After that, Artemis III will take a crewed spacecraft for a moon landing. Finally, Artemis IV will fly to a space station near the moon.Over the course of the Artemis missions, NASA plans to eventually send the first female astronaut and the first astronaut of color to the moon.Nov 15, 9:01 PM EST Artemis mission has suffered months of delaysThe Artemis mission has suffered a series of setbacks since an original launch date in late August that was expected to feature Vice President Kamala Harris in attendance among about 100,000 spectators.NASA called off that initial takeoff, set for Aug. 29, after a defective sensor prevented one of the rocket’s engines from cooling down to a temperature required before ignition.Days later, a second launch attempt on Sept. 3 was scrubbed after the space agency identified a liquid hydrogen leak.A third planned launch attempt, on Sept. 27, faced postponement due to Hurricane Ian. The rocket was moved off the launchpad to protect it, as Ian wrought destruction along its path northward from Florida to the Carolinas.Copyright © 2022, ABC Audio. All rights reserved.
