The NASA moon rocket will be delivered to the launch table two days ahead of schedule

NASA had previously planned that the SLS launch vehicle with Orion as part of the moon mission Artemis I would be sent to the launch table on 18 August. The agency now reported that the launch would start two days earlier, today at 3 p.m. local time. On the weekend, NASA engineers completed the final test of the launch vehicle, and it was declared fully ready for shipment to the Moon.

The main step in the final test was to prepare the emergency flight interruption system. The most important moment of this phase was the installation of batteries to power the interruption system. The difficulty is that batteries maintain the system ' s performance for 20 days, after which the entire system needs to be reset, including the replacement of batteries. This means that if the missile has not started within 20 days of the end of the test, it must be returned to the hangar for refurbishment.

The completion of the Flight Cancelling System test on 14 or 15 August means that the SLS missile cannot be placed on the launch deadline of 5 September. In this case, NASA was able to approve an extension of the Flight Cancelling System for 5 days, totalling 25 days. The Artemis I mission has three approved launch windows: 29 August and 2 and 5 September. If, for some reason, the missile cannot be launched and the hurricane season begins in Florida at this time, the next attempt will not take place before the end of October.

The SLS rocket was already driven from the hangar to the start-up table and back. The first run-off took place in April and ended with the failure of the general rehearsal with fuel refuelling. The second run-off took place in June and was also incomplete. In all cases, there were problems with the cryogenic fuel refuelling systems that leaked. Let's hope the missile takes off on the third time.

The launch will begin today at 3 p.m. local time, and the Artemis I mission will be equipped with dummies and toys from the European Space Agency to the Moon. The mission will last about four weeks. The Orion ship will return to Earth in high orbit and will enter the ocean. If it is successful, the astronauts will board the moon after 2024.
