Regolith

She leads a team that will study samples of regolith, or Moon soil, collected in 1972 near the Apollo 17 landing site of Taurus-Littrow Valley on the eastern rim of Mare Serenitatis.

The Mars 2020 Perseverance rover will also characterize the planet's climate and geology, pave the way for human exploration of the Red Planet, and be the first planetary mission to collect and cache Martian rock and regolith.

The rover will characterize the planet’s geology and past climate and be the first mission to collect and cache Martian rock and regolith, paving the way for human exploration of the Red Planet.

The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) is scheduled to fire its thrusters for about seven minutes, taking it out of the asteroid’s orbit and setting it on a homeward course.

Martian dust is called regolith.

The probe will summarize Mars' geology and past climate, and become the first spacecraft to collect and store Martian rocks and regolith, paving the way for humans to explore the Red Planet.

The structures on the surface were gone from normal view, pulverized into regolith across a span of aeons.

The soil sample, called LZS-1, is the latest in a list of lunar regolith simulants of varying quality that have been developed to help Nasa and other space agencies around the world prepare for missions to the Moon.

What Interlune is trying to do [the startup aims to develop robotic lunar mining camps] is far from child’s play. Helium-3, an industrially prized cousin of the isotope of the gas we use to fill party balloons, is rare on Earth. […] Even if Interlune can find lunar regions with higher concentrations, collecting a commercially viable amount of helium-3 means developing and transporting to the moon machines that can chew through millions of tons of regolith, the loose debris that covers the lunar surface from billions of years of micrometeorite impacts. Autonomously. With no boots on the ground to repair them as they kick up dust more abrasive than anything on Earth. […] Interlune expects less than 1% of the gas they’ll get when they crush lunar regolith will be helium-3 – it’s estimated to exist only in the single- to double-digit parts per billion. To separate it from balloon helium and hydrogen, they’re cooling it all beyond negative 450 degrees Fahrenheit, at which point the other gases will liquefy and the helium-3 can be siphoned off.
