At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there. [5] [6]
No extraterrestrial life has ever been discovered. But if extraterrestrial life exists, it may be vulnerable to interplanetary contamination by foreign microorganisms. Some extremophiles may be able to survive space travel to another planet, and foreign life could possibly be introduced by spacecraft from Earth. If possible, some believe this ...
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.

Scientists have identified a super resilient desert moss species in China's western region of Xinjiang that could help sustain possible colonies on Mars, a study by the Chinese Academy of Sciences ...
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
Looking to the future, we expect that this promising moss could be brought to Mars or the Moon to further test the possibility of plant colonization and growth in outer space.” S. caninervis is ...
Space flight occurs beyond the Earth's atmosphere, and space flight simulators feature the ability to roll, pitch, and yaw. Space flight simulators use flight dynamics in a free environment; this free environment lets the spacecraft move within the three-dimensional coordinate system or the x, y, and z (applicate) axis.
