Calcium can also be used to fabricate silicon-based solar cells, requiring lunar silicon, iron, titanium oxide, calcium and aluminum. [50] When combined with water, lime (calcium oxide) produces significant amounts of heat. hydrated lime (calcium hydroxide) meanwhile absorbs carbon dioxide which can be used as a (non-replenishing) filter.
Silicon-based life Like carbon, silicon can create molecules that are sufficiently large to carry biological information; however, the scope of possible silicon chemistry is far more limited than that of carbon.

Whether there is life on Titan, the largest moon of Saturn, is currently an open question and a topic of scientific assessment and research. Titan is far colder than Earth , but of all the places in the Solar System , Titan is the only place besides Earth known to have liquids in the form of rivers, lakes, and seas on its surface.
The only ways in which potential life could avoid either an inferno or a deep freeze would be if the planet had an atmosphere thick enough to transfer the star's heat from the day side to the night side, or if there was a gas giant in the habitable zone, with a habitable moon, which would be locked to the planet instead of the star, allowing a ...
An upper bound on the cost of launching material from the Moon might be about $40,000,000 per kilogram, based on dividing the Apollo program costs by the amount of material returned. [ 70 ] [ 71 ] [ 72 ] At the other extreme, the incremental cost of launching material from the Moon using an electromagnetic accelerator could be quite low.
The silicon disc with goodwill messages left on the Moon by Apollo 11 astronauts. The Apollo 11 goodwill messages are statements from leaders of 73 countries around the world on a disc about the size of a 50-cent piece made of silicon that was left on the Moon in 1969 by the Apollo 11 astronauts.

Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
