However, the assessment still finds the enormous cost of SLS hard to manage for NASA and damaging to its long term " Moon to Mars" plans. To remedy this, the report makes a number of recommendations to NASA management to increase transparency, accountability and affordability of the SLS booster and engine contracts, including switching from "cost-plus" awards towards a fixed-price contract structure. But the "complexity of developing, updating, and integrating new systems along with heritage components proved to be much greater than anticipated," according to the report. Responsibilities: In this role, you will lead a functional engineering team responsible for engine control strategies used to control all rocket engines at Blue Origin. The use of heritage RS-25 engines and boosters from the space shuttle and Constellation programs for the new SLS rocket was intended to bring significant cost and schedule savings over developing new systems. These significant increases were caused by a variety of long-standing, interrelated management issues impacting both the SLS development campaign and the wider Artemis program, the report notes, including "some of which represent potential violations of federal contracting requirements." The BE-7, a turbomachinery-based engine using the most efficient propellants, is optimal for deep-space maneuvers and landing on the Moon, said Brent Sherwood, vice president, Advanced Development Programs, Blue Origin.
