NASA postpones test of Space Launch System (designed for missions to the moon and Mars) for security reasons
NASA has postponed critical tests of the super-heavy launch vehicle Space Launch System (SLS). On Sunday, April 3, the agency planned to refuel the rocket as part of a “dress rehearsal” to recreate the countdown to the upcoming launch of Artemis 1. However, shortly after 12:00 Eastern Time (19:00 Kyiv time) NASA announced the cancellation of tests due to problems with the mobile rocket launch platform.
For safety, we've stopped the #Artemis I wet dress rehearsal. Teams are meeting now to assess next steps. We are looking at Monday, April 4 as the next opportunity to resume operations, and will have a media briefing later today. Check here for updates. https://t.co/pweviGRjwg

NASA staff had to start refueling a rocket of 700 thousand gallons (about 3.2 million liters) of liquid fuel. But before that, the agency found that the system on the launcher, which is vital for missile safety, has failed. She lost the ability to create the correct pressure on the platform.
Fans are needed to create positive pressure indoors inside the mobile launcher and prevent the ingress of hazardous gases. Without this capability, technicians cannot safely start loading fuel into the main stage of the rocket and the intermediate cryogenic stage.
The space agency may repeat the test on April 4, although it will depend on several factors, including the availability of fuel. Successful testing will be an important milestone for NASA. The agency has spent decades and more than $23 billion developing the Space Launch System. This rocket is a central element of many of NASA’s plans to explore the moon and other missions.
