Each tube of simulant comes with a Christmas card showing the sample in space. The inside flap tells the story of the flight and gives additional information about simulated Martian regothith.


On Nov. 2, 2018, the students of Earth to Sky Calculus launched test tubes of simulated Mars dirt to the stratosphere. The samples flew 109,235 feet above the Sierra Nevada mountains of Central California. At that altitude, the test tubes experienced doses of cosmic rays, UV radiation, and low air pressure very similar to that on the actual surface of Mars.

The technical name of the dirt the students flew is "MMS-1 Mars Regolith Simulant." Mojave Mars Simulant (MMS) was developed by NASA and JPL scientists to test the Mars Phoenix Lander. It was designed to closely simulate the surface of Mars more so than previously available simulants, especially when in contact with water.

Just add water to these samples to create your own Martian Mud. They can also be used for unique gardening experiments: Can you grow tomatoes in simulated Mars Dirt? These samples are great kickstarters for school Science Fair Projects. Flight data are available upon request to support young scientists.
