Rosalie Geeck Krob ’08 is a Propulsion Project Engineer for Aerojet Rocketdyne, the company responsible for the launch, entry, descent, and landing phases for NASA's Mars Perseverance Rover.

Learning the spacecraft's landing (after a 293 million mile journey!) was successful was an emotional experience for Rosie. Aerojet Rocketdyne’s propulsion was crucial to the descent that NASA refers to as “seven minutes of terror.” Traveling at 12,500 miles per hour, the spacecraft must transition from that incredible speed to landed in about seven minutes. According to NASA’s website, “To safely go from those speeds down to zero, in that short amount of time, while hitting a narrow target on the surface, requires ‘slamming on the brakes’ in a very careful, creative, and challenging way.”

After graduating from MCA in 2008, Rosie went on to complete a bachelor’s degree in aeronautical and astronautical engineering with a minor in astrophysics and earned a master’s degree in aeronautics and astronautics, both from Purdue University.
