Should the cancellation of take-off be seen as a failure?

On Saturday, September 3, the take-off of the SLS was again canceled by NASA. We should be talking about a failure or a failed launch, as has often been said and written in the media. Obviously not. Here because.

[EN VIDÉO] See what the Artemis mission launches will look like
At the end of 2021, NASA’s new heavy launcher, the Space Launch System (SLS), will launch the first Artemis I mission to the moon. Here’s what its first flight will look like.

Surprisingly, several media outlets have described the Artemis I launch reports. An analysis that surprises us. We speak of bankruptcy when, for more than two years, SpaceX announce that your future Starship will conduct a test flight within 6 months? Certainly not. Same for me Ariadne 6 which is not yet ready to fly although its first flight was scheduled for July 2020.

Artemis I, which does not take off despite two attempts, is obviously not a failure for the NASA and its industrial partners. It will be considered a failure if the launcher flies away and explodes, if the vehicle of Orion fails to participate moon or crashes to its surface and fails to return to Earth safely. All other adventures obviously cannot be considered a failure. These are incidents, certainly more or less binding, inherent in any program under development or in the qualification phase.

On August 29, NASA had to cancel the flight after several Technical Problems and when one of the four main stage RS-25 engines failed to reach the proper temperature to ignite. September 3 is a fuel leak occurred during the filling of the tanks of the launcher which prompted NASA to suspend the procedure and therefore to cancel the launch.

Normal ignition delay

Although SLS is built around technologies mastered and inherited from previous programs, including those of the space shuttle and Saturn V for example, this launcher is still new. These ignition delays are therefore not very surprising and quite common for new launchers. This first mission of the Artemis program is primarily a demonstration flight. Not only must he qualify the launcher, but he must also demonstrate the vehicle’s capability Orion and its ESM service module to operate in a wide variety of flight configurations.

Since the last Apollo mission to land on the moon in December 1972, we have been waiting for humans to return to the moon for nearly 50 years. We are just a few years away!
