The US space agency will try again to launch a massive lunar rocket on September 3, five days after the first attempt was cancelled. Agency officials confirmed the new date at a press briefing on Tuesday. The teams will meet again on September 1 to assess the situation.
The first launch of the new rocket on Monday was delayed due to a problem with one of its engines and a malfunctioning tank vent valve on the main rocket. The malfunctions are related to the temperature readings on the third of the four main rocket engines. A faulty sensor showed that the engine temperature was not cold enough, but subsequent tests confirmed that the required degree of cooling was still achieved.
To remedy the situation, work will be carried out to replace the sensor on the launch pad and adjust the launch procedure.
The Artemis mission will be the first major flight as part of NASA’s ambitious plan to send the first woman and the first person of color to the surface of the moon as early as 2025.
The current launch is to test Boeing’s Space Launch System base rocket and a new crew capsule called Orion, designed by Lockheed Martin and designed for long flight.
As a result of the successful launch, the SLS will send an uncrewed Orion on a multi-week mission, along with a host of payloads and sensors to track the journey.
The capsule will enter lunar orbit and enter deep space before returning to Earth and landing in the Pacific Ocean near San Diego. NASA plans to stress test systems before launching crewed missions.
NASA does not rule out a second cancellation of the launch – in this case, the next attempt can be made in 48 hours.
