Curiosity To Dig Deeper For Evidence Of Life On Mars
2012-07-06 07:24:55

Lee Rannals for redOrbit.com - Your Universe Online According to a new study to be published in Geophysical Research Letters, NASA's new Curiosity rover may be capable of digging deep enough to find evidence of ancient life on Mars. The findings suggest optimal depths and locations to probe for organic molecules like those that compose living organisms could be reached through the Curiosity rover, which is expected to land on the Red Planet on August 5, 2012. If there is any evidence...

Carbon Detected In Martian Meteorites

Lee Rannals for RedOrbit.com 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. The researchers were able to detect strong evidence that complex carbon chemistry has taken place on Mars. "These findings show that the storage of reduced carbon molecules on Mars occurred throughout the planet's history and might have been similar to processes that occurred on the ancient...

Life Discovered On Mars, Researchers Claim

A new analysis of data collected by the NASA Viking mission has determined that there is life on Mars. Two Viking probes landed on Mars in 1976 and carried out an experiment that heated soil to try and create a chemical reaction that would indicate the presence of life. One of the three experiments, which were known as the "Labeled Release" (LR) experiment, hinted to the presence of life on Mars, while the others did not. A mathematical analysis of the samples found that salts in the...

Paul Mahaffy, the scientist in charge of the largest instrument on NASA's next Mars rover, watched through glass as clean-room workers installed it into the rover. The specific work planned for this instrument on Mars requires more all-covering protective garb for these specialized workers than was needed for the building of NASA's earlier Mars rovers. The instrument is Sample Analysis at Mars, or SAM, built by NASA's Goddard Space Flight Center, Greenbelt, Md. At the carefully selected...

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. A new theory to explain what happens to these carbon-based molecules is presented in an article published in Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. "There may be no 'safe haven' for these organic molecules on Mars," conclude Ilya Shkrob, Sergey Chemerisov, and Timothy...

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. The National Aeronautics and Space Administration said the source for that sample will be the "Snow White" trench on the eastern end of the area reachable with Phoenix's robotic arm. In July that trench yielded a sample that was found to contain water ice. The wet chemistry laboratory mixes Martian soil with purified water from Earth as part of the...

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. NASA's Phoenix spacecraft earlier this month detected the chemical perchlorate, a highly oxidizing salt, in soil samples dug up from near the Martian surface. On Earth, it can be found naturally in the arid Atacama Desert in Chile where some extreme organisms use it as a source of energy. "We know that...

NASA's Phoenix Lander may have discovered the presence of perchlorate, a chemically reactive salt, in soil samples taken from the surface of Mars, NASA scientists said on Monday. If the finding is confirmed, it could add doubt to the theory of conditions on the planet being able to sustain life. The space agency will be working to determine whether the perchlorate came from the Martian soil or the spacecraft. Perchlorate is an oxidizing substance used in rocket fuel. It is known to be...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
