Strumento a bordo della sonda Mars Global Surveyor che è stato l'ottenimento di dati topografici dal marzo 1999. MOLA trasmette impulsi laser infrarosso focalizzato verso Marte a una velocità di dieci volte al secondo e misura il tempo di riflessione dell'orbita per determinare la gamma della navicella MGS alla superficie marziana. Gli scienziati usano la gamma di misure per la costruzione di precisi profili topografici e mappe di Marte in dettaglio insuperabile.
Industry:Astronomy
Study of the origin, distribution, and destiny of life in the universe. These are interdisciplinary studies involving astronomers, astrophysicists, biologists, chemists, geneticists, geologists, paleontologists, planetary scientists, and specialists from other scientific fields. Three broad themes of astrobiology: Is there life elsewhere in the universe? How did life begin and evolve? What is the future for life on Earth and beyond?
Industry:Astronomy
Mixture of gases that surround and are gravitationally attached to a planet.
Industry:Astronomy

Industry:Astronomy
An element with atomic number 8; symbol: O. It is actually the most common element in the crusts and mantles of the inner planets and rocky moons, making up all silicate minerals. Along with hydrogen, carbon, and nitrogen, oxygen is essential to life.
Industry:Astronomy
The spontaneous breaking apart, or decay, of unstable nuclei in isotopes. The unstable radioactive isotope is called the parent, and the products of the decay of the parent are called the daughter isotopes.
Industry:Astronomy
Solid rock or mineral fragments transported and deposited by wind, water, gravity, or ice; precipitated by chemical reactions; or secreted by organisms; accumulated as layers in loose, unconsolidated form.
