Latest Viking biological experiments Stories
NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory’s drill.
According to a new study to be published Geophysical Research Letters, NASA's new Curiosity rover may be capable of digging deep enough to find evidence of ancient life on Mars.
Carbon, a building block for creating life, has been detected in a Martian meteorite that landed on Earth, according to a Carnegie Institution for Science study.
A new analysis of data collected by the NASA Viking mission has determined that there is life on Mars.
Researchers will use SAM and nine other science instruments on Curiosity to study whether one of the most intriguing areas on Mars has offered environmental conditions favorable for life and favorable for preserving evidence about whether life has ever existed there.
The ongoing search for evidence of past or present life on Mars includes efforts to identify organic compounds such as proteins in Martian soil, but their absence to date remains a mystery.
The next soil sample the U.S. space agency's Phoenix Mars Lander obtains will go to the fourth of its four wet chemistry laboratory cells.
By Alicia Chang Associated Press LOS ANGELES -- Traces of a rocket fuel ingredient found in the Martian soil would not necessarily hinder potential life, mission scientists said Tuesday.
