NASA’s Mars Ascent Vehicle (MAV), under the management of NASA’s Marshall Space Flight Center, has achieved significant milestones in its progress towards the Mars Sample Return program. Successfully testing solid rocket motors and passing the Preliminary Design Review, MAV is set to launch in 2028 as part of a partnership with the European Space Agency. The MAV’s mission is to bring back Martian samples to Earth for scientific study, providing insights into Mars’s ancient history and potential signs of past life.
The MAV’s preparation and schedule include extensive testing and analysis of its design and components. It will travel on the Sample Retrieval Lander during its launch from Earth, undergo a two-year journey to Mars, and then nearly a year of collecting and receiving samples from NASA’s Perseverance Rover.
To achieve a successful MAV launch from Mars, the team conducted testing on two solid rocket motors (SRM1 and SRM2). The SRM1 propels MAV away from Mars, while SRM2 spins MAV’s second stage to place the sample container in the correct Mars orbit for retrieval by the Earth Return Orbiter.
Recent achievements include successful testing of the solid rocket motor designs, particularly the supersonic splitline nozzle, which proved successful and achieved the sixth of nine technology readiness levels. The MAV team also completed the Preliminary Design Review, paving the way for further improvements before the Critical Design Review.
The development of MAV is a collaborative effort involving NASA’s Marshall Space Flight Center, Lockheed Martin Space, and Northrop Grumman, while the Mars Sample Return Program is supervised by NASA’s Jet Propulsion Laboratory in Southern California.

Frequently Asked Questions (FAQs) about Mars Sample Return
What is the Mars Ascent Vehicle (MAV)?
The Mars Ascent Vehicle (MAV) is a spacecraft developed by NASA’s Marshall Space Flight Center for the Mars Sample Return program. Its mission is to bring back Martian rock and soil samples to Earth for scientific study.
What is the purpose of the Mars Sample Return program?
The Mars Sample Return program is a strategic partnership between NASA and the European Space Agency (ESA). Its main goal is to collect scientifically selected samples from Mars and return them to Earth, potentially revealing insights into Mars’s ancient history and signs of past life.
When is the MAV set to launch?
The MAV is scheduled to launch in 2028. It will travel on a two-year journey to Mars and return with the samples in the early 2030s.
What are the key milestones achieved by MAV?
The MAV recently passed its Preliminary Design Review and successfully tested its solid rocket motors. These achievements demonstrate the readiness of the technology for further development and launch.
How will the MAV collect and return the samples?
After NASA’s Perseverance Rover collects samples on Mars, they will be transferred into a sample container in the MAV’s nose. The MAV will then launch from Mars into orbit around the planet, releasing the sample container for the Earth Return Orbiter to capture and bring back to Earth.
What is the significance of the supersonic splitline nozzle?
The supersonic splitline nozzle is a critical component of the MAV’s rocket motors. It has achieved the sixth of nine technology readiness levels, indicating its successful performance in vacuum bench and full-scale hot fire testing.
Who are the key partners and contractors involved in the MAV project?
The MAV project is a collaboration between NASA’s Marshall Space Flight Center, Lockheed Martin Space, and Northrop Grumman. Lockheed Martin serves as the overall system integrator, while Northrop Grumman provides the first and second stage main propulsion systems. The Mars Sample Return Program is supervised by NASA’s Jet Propulsion Laboratory (JPL) in Southern California.
What will the collected Martian samples be used for?
The samples brought back by the MAV will be studied using advanced instrumentation from around the world. Scientists hope to gain valuable insights into Mars’s history, including its early evolution and the potential for past life on the planet.

wow this is so cool! mars ascent vehicle mav theyre sending a rocket to mars to get rock samples and bring them back to earth! nasa and esa working together for science awesome
i wonder how much those rockets cost, but hey, its all for science and space exploration! go MAV go!
mars sample return program sounds epic! cant wait to see those rock samples from mars! hope they find signs of past life on the red planet
