Artemis: SLS rocket to the moon with budget problems

A new audit NASA Rocket says development is likely to have ‘additional cost and schedule increases’ SLS.

It has four RS-25 engines per launch and 16 engines salvaged from space shuttles are kept in reserve.

Subsequently, the NASA Aerojet will switch to Rockettine-developed RS-25E engines, which will be 30% cheaper and 11% more powerful. It also uses solid rocket propellants supplied by Northrop Grumman.

Unfortunately, the old technology that is still being used causes problems.

For example, only 5 out of 16 engine adaptations have been completed, and the range and cost increases also affected the booster contract. The latter is the biggest problem, rising from $2.5 billion to $4.4 billion since the announcement. Sageand pushed the schedule back five years.
