At present, except for the moon, the rocks of other GC and its extended mod planets can only be used as common rocks, and can not extract useful resources like moon turf and moonrocks. Therefore, I have some suggestions in this regard, which can be used to make use of these resources.
Although there is no moon-like sample return to Mars (perhaps waiting for Musk…), half a century of remote sensing and ground-surface inspection have basically analyzed the surface and shallow elements of the planet.
Mars is a terrestrial planet that consists of minerals containing silicon and oxygen, metals, and other elements that typically make up rock. The surface of Mars is primarily composed of tholeiitic basalt,although parts are more silica-rich than typical basalt and may be similar to andesitic rocks on Earth or silica glass. Regions of low albedo suggest concentrations of plagioclase feldspar, with northern low albedo regions displaying higher than normal concentrations of sheet silicates and high-silicon glass. Parts of the southern highlands include detectable amounts of high-calcium pyroxenes. Localized concentrations of hematite and olivine have been found.Much of the surface is deeply covered by finely grained iron(III) oxide dust.
The Phoenix lander returned data showing Martian soil to be slightly alkaline and containing elements such as magnesium, sodium, potassium and chlorine. These nutrients are found in soils on Earth, and they are necessary for growth of plants.Experiments performed by the lander showed that the Martian soil has a basic pH of 7.7, and contains 0.6% of the salt perchlorate.This is a very high concentration and makes the Martian soil toxic (see also Martian soil toxicity).

Consideration may be given to the by-products of hematite, lignite, basalt, silicon dioxide, olivine, wollastonite, water and methane.
The atmosphere of Mars can be cryo-distilled from carbon dioxide, nitrogen,argon and methane.
At present, both Hayabusa and Hayabusa 2 in Japan have returned asteroid samples, and OSIRIS-REx in the United States is also on the way back (and wait a few years…). The detection shows that the composition of different asteroids is not the same, due to GC Three different kinds of asteroid rocks have been added, and it can be considered that their by-products are different.
Hayabusa(25143 Itokawa,brighter S-type):
In 2013 JAXA announced that 1500 extraterrestrial grains had been recovered, comprising the minerals olivine, pyroxene, plagioclase and iron sulfide. The grains were about 10 micrometers in size. JAXA performed detailed analyses of the samples by splitting particles and examining their crystal structure at SPring-8.
Dust from Itokawa was found to be "identical to material that makes up meteorites."Itokawa is an S-type asteroid whose composition matches that of an LL chondrite.

Hayabusa2 (162173 Ryugu,Darker C-type):
This result showed that most meteorites originating from C-type asteroids are too fragile to survive the entry into Earth’s atmosphere.The images from the camera of MASCOT, which is called MASCam, showed that surface of Ryugu contains two different almost black types of rock with little internal cohesion, but no dust was detected. One type of rocky material on the surface is brighter with a smooth surface and sharp edges. The other type of rock is dark with a cauliflower-like, crumbly surface. The dark type of rock has a dark matrix with small, bright, spectrally different inclusions. The inclusions appear similar to CI chondrites.An unanticipated side effect from the Hyabusa2 thrusters revealed a coating of dark, fine-grained red material.

Since it is only a month since the sample is returned, it will take more time to analyze the sample, so there is no more sample analysis for the time being…
