Regolith Simulant Bundle - 3 kg

This bundle is your team's official entry into the RIOT Challenge (Regolith Innovation for Off-World Technologies). Buying it registers your team as a participant and gets you the simulant for your research.

What's included

• 3 kg of research-grade regolith simulant, your choice of LHS-1, LMS-1 or MGS-1
• RIOT Challenge entry fee, so your team is officially in
• Free shipping worldwide
• RIOT stickers for your team

How to enter

Step 1: Choose your simulant

Choose the surface your experiment is about.

• LHS-1 (Lunar Highlands). A light-colored, anorthosite-rich simulant of the Moon's highlands, the terrain around the lunar south pole where Artemis missions are headed. Pick this if your proposal targets south-pole operations or highlands terrain, or if it covers excavation, construction or dust on most of the lunar surface. LHS-1 specs
• LMS-1 (Lunar Mare). A dark, basalt-rich simulant of the lunar "seas," the plains where the Apollo missions landed. Pick this if your proposal is set in a mare region or depends on iron- and titanium-bearing minerals, for example oxygen or metal extraction. LMS-1 specs
• MGS-1 (Mars Global). A simulant of typical Martian soil, built from data collected by NASA's Curiosity rover. Pick this if your proposal is set on Mars, such as plant growth, Martian construction materials, water extraction or rover mobility. MGS-1 specs

Step 2: Submit your proposal

Download the Research Proposal template from the RIOT Challenge page. Fill it in, including which simulant you chose, and email it to us as a PDF with your team details. Submissions are open November 1 to February 1.

Step 3: Buy your bundle

Once your proposal is submitted, buy the bundle in the size that fits your experiment. Select the simulant you named in your proposal.

• 3 kg is best for bench-scale work, such as small plant-growth pots, chemistry or extraction tests, sintered or printed test coupons, sensor calibration, and dust tests. It's enough for a few rounds of trials.
• 5 kg is best for hands-on hardware and larger samples, such as small excavation or wheel tests, building blocks or bricks, 3D-printing runs, or any experiment with many replicates. It also gives you room to repeat a trial if something goes wrong.

Rule of thumb: add up the simulant each trial uses and multiply by the number of trials you plan, then add some extra for mistakes. If that total is more than about 2.5 kg, choose the 5 kg bundle.

The first 25 teams get 10% off with code RIOT10. International teams may owe local import duties or taxes on delivery.
