Water is one of the simplest molecules, composed of one oxygen and two hydrogen atoms, and can be found in all celestial bodies of the solar system. However, water is only useful for life in a liquid state, and extraterrestrial water is commonly found as water vapor or ice. Liquid water also has several properties that are beneficial for lifeforms.
Cosmic dust – also called extraterrestrial dust, space dust, or star dust – is dust that occurs in outer space or has fallen onto Earth. [ 1 ] [ 2 ] Most cosmic dust particles measure between a few molecules and 0.1 mm (100 μm ), such as micrometeoroids (<30 μm) and meteoroids (>30 μm). [ 3 ]
Water can persist at higher temperatures than normal in the form of hydrated minerals: those minerals which can bind water molecules at the crystalline level. Salts, including halite (table salt, NaCl) are ionic and attract individual, polar water molecules with electrostatic forces. Alternately, the parent mineral may be e. g., sulfate, and ...
Most of the molecules detected so far are organic. The only detected inorganic molecule with five or more atoms is SiH 4. [14] Molecules larger than that all have at least one carbon atom, with no N−N or O−O bonds. [14] Carbon monoxide is frequently used to trace the distribution of mass in molecular clouds. [15]
Although trace amounts of water were found in lunar rock samples collected by Apollo astronauts, this was assumed to be a result of contamination, and the majority of the lunar surface was generally assumed to be completely dry. [22] However, a 2008 study of lunar rock samples revealed evidence of water molecules trapped in volcanic glass beads ...

Lunar sample 15415, also known as the "Genesis Rock"Extraterrestrial material refers to natural objects now on Earth that originated in outer space. Such materials include cosmic dust and meteorites, as well as samples brought to Earth by sample return missions from the Moon, asteroids and comets, as well as solar wind particles.
On Wednesday, Aug. 7, the agency held a news conference giving an update on the two astronauts who have been in outer space for 63 days — approximately seven weeks longer than expected ...
