Regolith in a sentence

Spectral observations indicate that the surface regolith layer lacks hydration, citation citation but ice below the regolith is not ruled out. citation citation The impact crater Stickney imaged by the Mars Reconnaissance Orbiter in March 2008.

Russia hasn’t launched a mission to the Moon since Luna-24 returned to Earth in August 1976, carrying samples of lunar regolith.

At the same time, we'll develop a new constitutive model, as current formulas are not well-suited to 3D-printed concrete or lunar regolith.

While Neil Armstrong's boot print, still enshrined in lunar regolith, gathers dust - the US, China, Russia and their partners are racing to go back.

According to their post, “samples returned from the lunar surface confirm that lunar regolith is made up of 40–45% percent oxygen by weight, its single most abundant element.

According to calculations, if there was no degradation of the organics, Mars should have 60 ppm of organics from organics deposited into the regolith, averaged over its entire surface to a depth of a hundred meters (see page 10 of this paper).

Architects and scientists now envision subdividing Mars with compounds of thick-walled living pods, made by 3-D printers with ingredients like ice and regolith topsoil.

Volkert noted that some mission planners have proposed extracting metals from the lunar soil, or regolith, to use as building materials.

Although such reflectance properties are different from those of any terrestrial terrains, they are typical of the regolith surfaces of airless Solar System bodies.

Because of this process, older regolith appears more red in color compared to freshly exposed material.

Chlorine is very rare in lunar regolith, and a substantially faster rate of reproduction could be assured by importing modest amounts.

Chlorine is very rare in lunar regolith, so the design recycled it.

Consequently, the thin optical surface layer could be quite different from the regolith underneath, and not representative of the bulk composition of the body.

Ejecta blocks constitute the largest pieces of the regolith.

However, in the lowest landscape positions, water may saturate the regolith to such a degree that drainage and aeration are restricted.

Its small size would make the formation of significant amounts of regolith impossible.

The contribution from cosmic rays is negligible within all except the oldest regolith materials, and lithium spallation reactions are a lesser contributor than the production of 4 He by alpha particle emissions.

The Project Apollo missions deployed passive aluminum collectors in an attempt to sample the solar wind, and lunar soil returned for study confirmed that the lunar regolith is enriched in atomic nuclei deposited from the solar wind.

There, at a distance of convert from the LM, they sampled material from the vicinity of Flag Crater, which scientists believed penetrated through the upper regolith layer to the underlying Cayley Formation.

The seasonal effect is more important for smaller asteroid fragments (from a few metres up to about 100 m), provided their surfaces are not covered by an insulating regolith layer and they do not have exceedingly slow rotations.
