NASA has asked the US aerospace industry how it would go about "maximizing the long-term efficiency and sustainability" of the Space Launch System rocket and its associated ground systems.
The request comes as NASA and its chief contractor for the rocket, Boeing, are nearing the launch pad after a long, arduous, and expensive development process that has lasted more than a decade. The heavy lift SLS rocket, carrying an Orion space capsule, should finally make its debut during the first half of 2022.
