Technology Development for a Potential Hybrid Mars Ascent Vehicle

With Mars Sample Return mission concepts being considered for launch as early as 2026, technology development to enable this potential campaign is currently underway. One of the critical items in the campaign would be a Mars Ascent Vehicle, which would be responsible for getting the samples from the surface of Mars to orbit around Mars. This would be the first rocket launch from another planet. Therefore, several challenges arise due to the Martian atmosphere and remote location. A technology development program to determine the feasibility of a hybrid rocket for a Mars Ascent Vehicle is entering its fourth year. Highlights and successes of this program will be discussed.
