The repair work has been aimed towards plugging a hydrogen fuel leak in an **8-inch line** leading into the core stage of the **32-story [SLS rocket](https://yourviews.mindstick.com/view/81756/why-nasa-s-sls-rocket-is-so-special)**. That leak had forced **NASA** to call off a **September 3** launch that attempted of **Artemis 1**. It was the first uncrewed test flight of the [Artemis program](https://answers.mindstick.com/qa/114967/how-does-nasa-plan-to-return-humans-to-the-moon-through-the-artemis-program) which had aimed towards coming of astronauts to the moon. At the time of replacing the seal, engineers have also replaced the seal on a smaller **4-inch hydrogen** '**bleed line**' that even saw a leak in a scrubbed **August 29** launch attempt. As the repair work has been completed the [NASA](https://www.mindstick.com/news/1949/within-1-4-billion-deal-spacex-to-launch-five-nasa-missions-in-space) has been currently making it ready for a fueling test to take a look if the SLS rocket's hydrogen leaks were perhaps fixed. That test would be occurred as early as by **Saturday**, **September 17**, and would fill the **322-foot-tall** (98 meters) rocket with the **736,000 gallons** of liquid hydrogen along with liquid oxygen which would be required for launch. As per NASA's update on **Friday**, '**This demonstration would permit engineers to to keep a look at the new seals under cryogenic or supercold, conditions were expected to launch day and before continuing to the next launch try**.' On **Thursday** (Sept. 8), NASA officials have mentioned that they were [targeting](https://answers.mindstick.com/qa/34553/what-are-the-targeting-options-in-display-network-ads) **September 23** for next Artemis 1 launch try. A **September 27** date has been also available. Both launch [opportunities](https://www.mindstick.com/articles/12566/mba-courses-in-delhi-ncr-offer-you-many-opportunities-galore) would rely upon NASA fixing the [fuel leak](https://www.mindstick.com/news/1960/launch-of-nasa-s-artemis-1-moon-mission-s-fuel-leak-might-get-delayed) and the SLS rocket passing its fueling test. NASA has been required to secure a waiver rom the **U.S. Space Force** thus it would not roll the SLS back to its **Vehicle Assembly Building** for normal tests of the rocket's flight termination system. It has [considered as](https://www.mindstick.com/forum/156093/what-is-considered-as-more-significant-creating-content-or-building-backlinks) a system which was designed to destroy the rocket if it veers off the course during its launch. The future fueling would permit NASA to perform a so-called '**kick-start bleed test**' on the SLS rocket's four main engines. That test was designed to set the engines right down to a [temperature](https://www.mindstick.com/blog/300335/what-is-normal-body-temperature) of minus **420 degrees Fahrenheit** (minus 251 degrees Celsius) in order to organize them for their super-chilled propellant. Therefore, the agency was unable to perform the test at the time of first 2 Artemis 1 launch attempt.
