The test took place at the company’s Elkton facility in Maryland, which serves as headquarters for Northrop Grumman’s propulsion systems and controls business unit. This site specialises in the design and manufacture of solid and liquid propulsion systems for high-end defence and space applications.
“With this third successful full-scale static test, we have demonstrated a near-flight ready design using proven space materials and propellants,” said Jeff Bemis, programme manager of the Mars Ascent Propulsion System (MAPS) at Northrop Grumman. “We’ve been to Mars before using materials and propellants such as these.”
According to Bemis, the materials and propellants used in the motor have a strong record of performance and are well-suited for the harsh demands of space exploration and planetary protection. Northrop Grumman has previously supplied a dozen solid rocket motors for earlier Mars missions.
The purpose of the recent test was to confirm a change in the propellant formulation, aimed at improving overall vehicle performance. The propellant tested is part of the company’s established STAR™ motor line, which has been deployed in numerous near-Earth and deep space missions.
Jonathan Katz, MAPS Chief Engineer at Northrop Grumman, stated: “This test exemplifies Northrop Grumman’s ability to rapidly transition from design to hardware build and testing, while adhering to timelines and budgets.” He added that further testing and analysis will continue to ensure the motors meet the demands of future Mars missions, including thermal and mechanical challenges.
The test confirms the readiness of ascent propulsion systems for upcoming interplanetary missions, regardless of the landing technology used. Northrop Grumman says the development strengthens its position as a leader in enabling human exploration beyond Earth.
The company, a major player in global aerospace and defence, employs nearly 100,000 people and operates over 30 million square feet of manufacturing space. Its integrated approach spans design, development, and production to deliver innovative solutions for national security and space exploration.
