Astrobiology is etymologically gotten from the Greek ἄστρον, astron, "heavenly body, star"; βίος, bios, "life"; and - λογία, - logia, think about. The equivalent words of astrobiology are various; in any case, the equivalent words were organized in connection to the most essential sciences inferred in its improvement: cosmology and science. A nearby equivalent word is exobiology from the Greek Έξω, "outside"; Βίος, bios, "life"; and λογία, - logia, examine. The term exobiology was begat by sub-atomic scientist Joshua Lederberg.[25] Exobiology is considered to have a restricted extension constrained to pursuit of life outer to Earth, while branch of knowledge of astrobiology is more extensive and explores the connection amongst life and the universe, which incorporates the look for extraterrestrial life, additionally incorporates the investigation of life on Earth, its starting point, advancement and cutoff points.
It is not known whether life somewhere else in the universe would use cell structures like those found on Earth. (Chloroplasts inside plant cells indicated here.)[26]
Another term utilized as a part of the past is xenobiology, ("science of the outsiders") a word utilized as a part of 1954 by sci-fi essayist Robert Heinlein in his work The Star Beast.[27] The term xenobiology is presently utilized as a part of a more specific sense, to signify "science in light of remote science", regardless of whether of extraterrestrial or earthly (perhaps manufactured) root. Since exchange science analogs to some life-forms have been made in the research facility, xenobiology is presently considered as a surviving subject.[28]
While it is a rising and creating field, the subject of whether life exists somewhere else in the universe is an undeniable speculation and in this manner a legitimate line of logical request. In spite of the fact that once thought to be outside the standard of logical request, astrobiology has turned into a formalized field of study. Planetary researcher David Grinspoon calls astrobiology a field of regular rationality, establishing hypothesis on the obscure, in known logical theory.[29] NASA's enthusiasm for exobiology initially started with the improvement of the U.S. Space Program. In 1959, NASA supported its first exobiology extend, and in 1960, NASA established an Exobiology Program, which is presently one of four primary components of NASA's momentum Astrobiology Program.[2][30] In 1971, NASA financed the scan for extraterrestrial knowledge (SETI) to hunt radio frequencies of the electromagnetic range for interstellar interchanges transmitted by extraterrestrial life outside the Solar System. NASA's Viking missions to Mars, propelled in 1976, included three science tests intended to search for digestion system of present life on Mars.

Progressions in the fields of astrobiology, observational space science and disclosure of expansive assortments of extremophiles with remarkable ability to flourish in the harshest situations on Earth, have prompted to theory that life may perhaps be blossoming with a number of the extraterrestrial bodies in the universe. A specific concentration of ebb and flow astrobiology research is the scan for life on Mars because of its vicinity to Earth and land history. There is a developing assortment of proof to propose that Mars has already had a lot of water on its surface, water being viewed as a fundamental antecedent to the improvement of carbon-based life.[31]
Missions particularly intended to look for current life on Mars were the Viking project and Beagle 2 tests. The Viking results were inconclusive,[32] and Beagle 2 fizzled minutes after landing.[33] A future mission with a solid astrobiology part would have been the Jupiter Icy Moons Orbiter, intended to concentrate the solidified moons of Jupiter—some of which may have fluid water—had it not been crossed out. In late 2008, the Phoenix lander tested nature for at various times planetary livability of microbial life on Mars, and to look into the historical backdrop of water there.
In November 2011, NASA propelled the Mars Science Laboratory mission conveying the Curiosity meanderer, which arrived on Mars at Gale Crater in August 2012.[34][35][36] The Curiosity wanderer is right now examining the earth for over a wide span of time planetary tenability of microbial life on Mars. On 9 December 2013, NASA announced that, in view of confirmation from Curiosity examining Aeolis Palus, Gale Crater contained an old freshwater lake which could have been an affable situation for microbial life.[37][38]
The European Space Agency is as of now teaming up with the Russian Federal Space Agency (Roscosmos) and building up the ExoMars astrobiology wanderer, which is to be propelled in 2018.[39] While NASA is building up the Mars 2020 astrobiology meanderer and test cacher for a later come back to Earth.
