Artemis 1 mission, launch postponed… Retry on the 2nd of the next month (total)

NASA announces delay due to ‘fuel leak’
The reliability of the super-large projectile SLS – development efficiency seems to be controversial

[아시아경제 김봉수 기자] The launch of the American Artemis 1 mission, which was prepared to resume lunar exploration after 50 years, has been delayed by more than a rocket.

The National Aeronautics and Space Administration (NASA) announced on the 29th that at 8:33 a.m. EST (US time), the launch of the Artemis 1 mission, which was scheduled to be carried out at the Kennedy Space Center in Florida, was delayed due to engine failure. NASA is expected to explain the reason through an official briefing soon, but it is known that one of the four RS-25 engines has leaked fuel.

NASA is said to be trying to launch again on the 9th of next month as soon as possible. The Artemis 1 mission is a project that sends a manned capsule from Orion, a private company, to moon orbit by launching a 98-meter-long, super-large launch vehicle space launch system (SLS) developed by NASA and then returns. This is the first phase of the Artemis program, which aims to return mankind to the moon 50 years after Apollo 17 in 1972. In the Artemis 1 mission, the United States carried a doll that mimics the organs and skeletons of the human body and went to orbit the moon. After 2025, for the first time in 53 years, the Artemis 3 mission will be carried out to land people of color and women on the surface of the moon.

The SLS is a 32-story building with a total length of 98.1 m and was developed as a super-large projectile with the highest performance ever. It is 12m shorter than the Saturn V rocket that sent the Apollo spacecraft to the moon, but has a maximum thrust of 3991 tons, which is about 15% stronger. Two booster rockets, which take up 75% of the thrust at launch, exhibit the strongest and greatest performance ever. Each unit pushes up the SLS with a total weight of over 2600 tons with a thrust of about 1630 tons. Through the Artemis 1 mission, NASA planned to test key technologies such as verifying the performance of the SLS and transferring the Orion capsule to the lunar orbit, re-entrying the Earth’s atmosphere, and landing a drop.

NASA announced that it would resume launch soon, but this delay in launch is expected to intensify controversy over the development of SLS in the United States. Although $20 billion has been invested so far to develop the SLS, the reliability is being questioned, as problems were discovered one after another in the propellant injection experiments (WDR) conducted in April and June. In addition, since SpaceX, a private space company, is developing a starship, a super-large launch vehicle with similar performance, there is controversy over overlapping investment and wasting budget. In fact, NASA originally planned to develop the SLS at a cost of $10 billion by 2017, but the schedule was delayed and the cost more than doubled exponentially.
