NASA Artemis I lunar mission, why was the launch canceled twice in a row?

On Saturday, NASA halted its latest effort to launch the groundbreaking Artemis 1 moon rocket because it failed to stop a fuel leak detected during refueling. The spacecraft had been kept on the launch pad due to technical difficulties twice in the previous five days.


What is Artemis 1?

NASA’s return to the Moon will be marked by a number of missions, the first of which is the Artemis 1 unmanned mission. NASA intends to launch its brand new Space Launch System (SLS), with the spacecraft Orion spacecraft designed to accommodate astronauts seated atop the rocket.

It would be a milestone in the space agency’s efforts to bring humans back to the surface of the Moon for the first time since 1972.


The massive SLS rocket will carry the crew capsule around the Moon further than any spacecraft designed for humans has ever done, before returning to Earth for a splashdown in the Pacific Ocean.

Artemis 1, the first of several missions, is intended to successfully land astronauts on the moon. According to a press release from the agency, the unmanned mission will be the “1st integrated test of NASA’s Deep Space Exploration System”, which integrates the Orion spacecraft, the SLS rocket and ground structures. from the Kennedy Space Center in Cape Canaveral, Florida. .

“This is a mission that’s really going to do what hasn’t been done and learn what isn’t known,” said Mike Sarafin, Artemis 1 mission manager at NASA Headquarters in Washington, D.C. Press release. “It will open a path for people to follow on the next Orion flight, pushing the envelope to prepare for this mission.”

The launch from Complex 39B at Kennedy Space Center in Florida will serve as the starting point for SLS and Orion.

Since the Saturn V mission in the 1960s and 1970s, the SLS rocket has been the most dynamic ever built. Until now, it was stationed in a structure at the Kennedy Space Center in Florida.

According to, the rocket will travel 4.2 miles from NASA’s Vehicle Assembly Complex to the launch pad at an average speed of 1 to 2 miles per hour in about 10 hours. Perched on top of this rocket is the Orion spacecraft, designed to carry astronauts on orbital trips lasting up to a few weeks.

The crew of Artemis 2 will travel to lunar orbit in two years. The upcoming Artemis 3 mission will be the first to send a woman and a person of color to the surface of the moon. The official launch of such a mission is 2025, but many experts wonder if such a tight deadline can be met.

Which Artemis 1 rocket does it use?

The Space Launch System (SLS), dubbed NASA’s “mega moon rocket,” will make its debut with the Artemis 1 mission and, if successful, will become the most powerful rocket ever. The SLS is years behind schedule and over budget, relying on a combination of advanced technology and propulsion systems inherited from the Space Shuttle era.


However, there are many who support it in Congress and, as some have noted, like Casey Dreier of the Planetary Society, SLS never intended to compete with the recent advent of reusable spacecraft. However, some experts believe that the SLS will not outlast these more modern automobiles. But for now, it’s just a moon ride for them.

The initial cost of each Artemis mission is expected to exceed $4 billion. Critics point to expense and delays. Advocates point to the cutting-edge research, the potential for long-term sustainable human habitation on other planets, and the potential for inspiration such a program can offer society and business.

Who is Artemis?

The initiative aims to improve the representation of women in space exploration; 30% of its engineers are women. Additionally, the Artemis I mission will carry two mannequins that will be used to study how radiation affects women’s bodies so NASA can improve the protection of female astronauts.

Due to the fact that their bodies tend to exceed NASA’s maximum allowable radiation threshold sooner than men’s, female astronauts are currently less likely to be chosen for missions than male astronauts. On Artemis III, NASA plans to send the first woman and person of color to the Moon after 2024.

The name of the mission is quite symbolic: Artemis was a goddess identified with the moon by the Greeks and Romans, and she is now a feminist icon of modern times.

In ancient Greece, Artemis was a revered deity who was worshiped at least as early as the first millennium BCE, if not earlier. She was the child of Zeus, the supreme god of Olympus who presided over the universe from Mount Olympus. She was also the twin sister of Apollo, the god of the sun and oracles.


The goddess of woods and hunting, Artemis, was a virgin. Her resilience and independence have long served as an example to women in a variety of endeavors. In a poem titled “Artemis,” for example, author Allison Eir Jenks emphasizes women’s independence and freedom, writing, “I am no longer your godmother… your boss, your bus stop , your therapist, your trash…drawer.”

Artemis, the goddess of animals and wilderness, has served as an inspiration for environmental conservation initiatives since the goddess is seen as a role model for how a woman can use her influence to protect the environment.

Although the Greek Artemis was brave and strong, she was not always friendly or considerate of others, especially women. She was held responsible for the sudden death of a woman, especially when she was in labor, she was held responsible.

Over time, the incarnation of the goddess such as this has diminished. As feminism has evolved, Artemis has become a more well-known representation of female strength and independence.

Historically, NASA gave mythological characters their own mission names. Since the 1950s, a number of rockets and space systems have been named after Greek sky deities, such as Atlas and Saturn, whose Greek name is Cronos.

The Apollo program, which ran from 1963 to 1972 and launched the first men on the Moon in 1969, is referenced by NASA with Artemis. Artemis will continue where its twin brother left off in over 50 years, ushering in a more diverse era of human space exploration.

Why was the Artemis launch canceled by NASA?

Technical problems caused the bi-weekly cancellation of the launch of Artemis-1. The hydrogen feed pipe that filled the rocket’s center tank was leaking. More than three hours were invested by NASA engineers trying to find a solution. However, two hours before launch, engineers abandoned the effort.


According to the engineers, one of the rocket motors was not receiving proper cooling.

On Saturday, NASA attempted a second launch, although it warned it would cancel the attempt if it encountered similar problems. He only has two hours to fix the problems. Although the exact day has yet to be determined, it could be Monday or Tuesday.
