Fair Sky Materials Intelligence tells lunar missions what the ground is made of, and how it will behave when they drill it, heat it or build on it.

What it's good for

Drilling and excavation

How strong, hard and abrasive the ground is, so you can pick bits and power and predict wear.

Processing

Where the water, ilmenite and best melt feedstock are, and how much heat it takes to get them out.

Building

When regolith sinters and how strong the result is, for landing pads, roads and bricks.

Dust

Which fine grains fly fastest, stick to hardware and pose a health risk, and what they're made of.

SIFT

A dust sensor for the last seconds of landing.

When a lander touches down, its engine blasts dust sideways. SIFT rides on a lander leg, catches that dust, separates coarse grains from fine, and measures the composition of each. It turns every landing into a size-sorted sample of the site.

  1. 1
    CatchAn inlet facing the plume takes in exhaust gas and dust.
  2. 2
    SortThe gas turns toward the vents and heavy grains can't, so large grains land in the center and fine grains at the edge.
  3. 3
    MeasureA spectrometer under the window plate reads each ring.

  • Middle ringMedium grains: minerals mixed with glass.
  • EdgeFine grains: glass and weathered dust, the kind that damages hardware.

MoonGrade

A foundation model for lunar materials.

Every instrument sees only one side of a material. MoonGrade combines their data, checks it against material physics and predicts how the ground will behave, with an uncertainty on every result. It works with instruments already headed to the Moon, with or without SIFT.

Every result comes with an uncertainty.

Learned from data. Grounded in physics.

Spectral physics

How each mineral and ice makes its spectrum, and how mixing and grain size change it.

Chemistry balance

The minerals in the model must add up to the elements the instruments measure.

Grain and pore physics

How grains pack, how big the pores are, and how ice fills them and bonds the grains.

Mechanics and heat

How strength, wear and heat flow follow from the minerals, grains, pores and ice.

MoonGrade works on its own. SIFT gives it something no other instrument can: composition, grain size by grain size.

Grain size changes how regolith digs, flows, heats and even how its spectra look. Adding SIFT's size-sorted measurements sharpens every prediction MoonGrade makes, and every landing adds to what it knows.
