Jezero Crater Regolith Simulant [JEZ-1]

PRODUCT TYPE: Interesting Materials

This material has been engineered to be chemically and mechanically identical to the surface dirt of the landing site of Perseverance at Jezero Crater on Mars. 

Regolith is a mixture of dust, soil, broken rock and other organic materials. NASA/JPL uses this material to test their rovers' performance abilities on the planet and to determine how well crops can be grown on Mars.

The Jezero Delta Simulant (JEZ-1) was made to simulate anticipated materials in the Jezero Crater deltas that will be investigated by the NASA Mars 2020 rover. The simulant is a mixture of MGS-1 mineralogy with smectite clay, Mg-carbonate, and additional olivine that have all been detected from orbital remote sensing in the Jezero delta deposits.

The state of lithificaiton, mineralogy, and grain size distribution are likely variable throughout the Jezero deltas; JEZ-1 represents unconsolidated material, but can be compacted under various pressures to form a more cohesive solid.


To be clear, this is not from Mars, but it is exactly identical to what you would find at the Mars 2020 landing site on Mars.

Jezero is a crater on Mars located at 18.38°N 77.58°E in the Syrtis Major quadrangle. The diameter of the crater is about 49.0 km (30.4 mi). Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars.

Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff.

In 2007, following the discovery of its ancient lake, the crater was named for Jezero in Bosnia and Herzegovina, one of several eponymous towns in the country. In several Slavic languages, including Czech, Bosnian, Croatian, Slovakian, Serbian, Montenegrin, and Slovene, the word jezero (pronounced ['je.ze.ro]) means 'lake'.

In November 2018, it was announced that Jezero had been chosen as the landing site for the Perseverance rover of NASA's Mars 2020 mission. In November 2020, evidence of boulder falls was found on the slopes of the delta deposits that the rover is planned to explore, on the wall of Jezero itself as well as on the wall of a small (2-kilometre diameter) crater on the floor of Jezero.

Exactly as described. Fantastic item and a wonderful display piece! Love it!


super quick shipping !! !!


Great gift! Only thing I wish was included was an informational card to pair with the item.


I bought four of the simulant bottles for a friend's birthday, they arrived extremely well packaged and safe, all with an information pamphlet and securely sealed. He loved them! I recommend this shop!

Jezero Crater Regolith Simulant

I got to watch Perseverance’s 7 minutes of terror live while I was at work on my 10. It was a moment I’ll never forget. This Simulant is good token for anyone who shared in the wonder and excitement of Perseverance making history on February 18th, 2021.
