Artemis 1 is Launching on Saturday

NASA’s Moon rocket was initially scheduled to launch earlier last week but was delayed due to issues that have since been resolved. All indicators now point to a successful launch this coming Saturday. The Artemis 1 team decided to attempt a liftoff on Saturday, September 3, from NASA’s Kennedy Space Center in Florida following a meeting on September 1. The awaited launch is planned for a two-hour window that starts at 2:17 p.m. EDT (1817 GMT). Mike Sarafin, the mission manager for Artemis, said at a news conference on September 1 evening that “there’s no guarantee that we’re going to get off on Saturday, but we’re going to try.”

Artemis 1

The Artemis 1 mission will launch an un-crewed Orion capsule into lunar orbit and back within 37 days using a Space Launch System (SLS) rocket. It will be the inaugural flight for the SLS and NASA’s Artemis program, which seeks to establish a long-term human presence on and near the moon by the late 2020s. On Monday, August 29, Artemis 1 was initially scheduled to launch. Still, the mission team discovered a problem during the countdown: One of the four RS-25 engines that powered the SLS core stage wasn’t cooling down to the correct prelaunch temperature. According to NASA officials, this thermal conditioning prevents a shock when the engines ignite and is accomplished by “bleeding” supercold liquid hydrogen propellant into the RS-25s. The attempt on Monday was abandoned because the Artemis 1 team could not resolve the problem before the launch window closed.

Additionally, NASA has been working to resolve the technical issues that caused the launch to be postponed at the last minute on Monday during the original window of opportunity. According to the rocket’s program manager John Honeycutt, it initially appeared that one of the rocket’s four main engines was running too hot, but it turned out to be just reading from a “bad sensor.” Director of the launch Charlie Blackwell-Thompson said, “We were able to find what we believe to be the source of the leak and correct that.”

Artemis 1 would likely need to be moved off the launch pad and back to the enormous Vehicle Assembly Building at Kennedy Space Center to replace the sensor. On launch day, the team will leave the sensor in place and disregard any inaccurate readings because they don’t believe that’s necessary or desirable, according to a statement from NASA. The Artemis 1 team also investigated several other problems that surfaced during Monday’s countdown, which included a slight hydrogen leak and a crack in the foam that is a component of the thermal protection system for the SLS core stage. Team members reported that the leak was corrected by the evening of 2nd Sept. Additionally, the engine sensor problem and the foam crack call for only “incremental risk acceptance.” Sarafin said, “We’re comfortable with our flight justification and risk acceptance.”

The notoriously unpredictable Space Coast weather on Saturday might also force Artemis 1 to stay on the ground. The U.S. Space Force’s Space Launch 45 group’s weather officer, Melody Lovin, stated that there is a 60% chance of favorable conditions when Saturday’s window opens. Hence, things appear good for a launch attempt. Members of the mission team said that if Artemis 1 cannot take off on Saturday, another attempt will be made on Monday, September 5. Additionally, according to Loving, the weather on that day appears favorable. In general, she said, “the weather looks good.” “If there are times when we are considered to be in the red for weather, I wouldn’t be surprised. However, in the end, I don’t think the weather will be a deal-breaker for either launch window.”

Why Artemis 1

50 years have passed since the six Apollo moon landings from 1969 to 1972. Since then, space exploration has advanced dramatically. More than 500 astronauts have now traveled to space and back, spacecraft has left the solar system, and permanent space labs like the International Space Station (ISS) have been built. Exploratory missions have also visited Mars, Jupiter, and Saturn. The promise of transporting humans to new worlds, the possibility of landing and living on other planets, or traveling to the depths of space, possibly even encountering aliens, has remained stagnant since the return of the last of the 12 Apollo astronauts from the Moon in 1972.

For this reason, Artemis 1 is regarded as the beginning of a new space age. It is the first of several large-scale missions intended to return people to the Moon, investigate the viability of staying there for an extended period, and assess its feasibility as a launch platform for deep space explorations. Artemis 1’s mission goals appear to be very modest at first glance. Technically, it is only an Orbiter mission to the moon. There are no astronauts on board. Not even a lander or rover element is present. The Orion spacecraft for the mission will enter an orbit around the Moon, bringing it within 97 kilometers of the lunar surface.

However, the real Artemis mission is positioned to take advantage of the significant advancements in space technology over time. The main goal of Artemis 1 is to lay the groundwork for future, challenging, and ambitious missions. It transports several payloads in the form of CubeSats, miniature satellites, each outfitted with instruments designed for a particular investigation or experiment. These investigations have a long-term human presence in space and on the Moon as their primary focus.
