After a thwarted try earlier this week, NASA will attempt to launch its next-generation megarocket Saturday on a check flight to the moon, company officers introduced Tuesday.
The debut flight of NASA’s uncrewed House Launch System (SLS) rocket was scheduled to happen Monday, however the launch was called off after engineers encountered a temperature drawback with one of many booster’s core-stage engines because the rocket was being loaded with propellant.
Mission supervisor Mike Sarafin mentioned in a information briefing Tuesday that groups have been investigating the difficulty on the launch pad and the company might be able to strive the check flight, often known as Artemis I, once more this weekend.
NASA is now focusing on a two-hour launch window Saturday at Florida’s Kennedy House Middle, starting at 2:17 p.m. EDT.
Climate could also be a priority this weekend, with showers and attainable thunderstorms passing over Kennedy House Middle, mentioned Mark Burger, the launch climate officer with the U.S. House Drive.
Burger mentioned there may be presently a 60% probability of a climate violation, however added that there’ll seemingly be clear situations at factors in the course of the two-hour launch window.
“Showers are likely to have fairly a little bit of actual property between them, so I nonetheless suppose we’ve got a reasonably good alternative weather-wise to launch on Saturday,” he mentioned Tuesday in a information briefing.
If the check flight, often known as Artemis I, known as off as a result of climate, NASA officers mentioned they might strive once more on Sept. 5.
John Honeycutt, supervisor of the House Launch System Program at NASA’s Marshall House Flight Middle, mentioned the issue might have been a defective sensor on the rocket, however added that adjustments might be made to the fueling course of on Saturday.
Throughout Monday’s liftoff try, a liquid hydrogen line used to chill the rocket’s core-stage engines malfunctioned partway by the launch countdown. The SLS’s engines should be cooled to cryogenic temperatures previous to launch to keep away from surprising the system with ultracold gasoline when ignited.
Sarafin mentioned groups will start the engine cooldown earlier within the launch countdown Saturday, which can assist the programs attain the specified temperature previous to liftoff.

The uncrewed check flight is a six-week journey to orbit the moon. The expedition is designed to check each the massive SLS rocket and NASA’s Orion capsule earlier than the company sends astronauts again to the lunar floor.
NASA’s return to the moon program, Artemis, is called after the goddess of Greek mythology who was the dual sister of Apollo. As a part of the Artemis program, NASA envisions common missions to the moon to determine a base camp on the lunar floor, earlier than the company finally ventures to Mars.
