Martian Meteorite Yields More Evidence Of The Possibility Of Life On Mars

Katie Brewin/Aeron Haworth, The University of Manchester A tiny fragment of Martian meteorite 1.3 billion years old is helping to make the case for the possibility of life on Mars, say scientists. The finding of a ‘cell-like’ structure,...

Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...

Data will help scientists read Curiosity Mars rover samples for signs of life, says UMD coauthor of study published today in Nature. (PRWEB) April 16, 2014 Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study, published April 17 in the journal Nature, shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year...

Meteorite Reveals Martian Secrets
2013-11-21 07:06:46

April Flowers for redOrbit.com - Your Universe Online A new study has uncovered what may be the first recognized example of ancient Martian crust. The findings, published in Nature, are the work of Munir Humayun of Florida State University. His work is based on an analysis of a 4.4 billion-year-old Martian meteorite unearthed by Bedouin tribesmen in the Sahara desert. The rock, designated NWA 7533, might be the first recognized sample of ancient Martian crust and holds a wealth of...

Curiosity Sampling Confirms Earth Meteorites Are From Mars
2013-10-16 16:04:54

[ Watch the Video: Martian Roots In Many Meteorites ] Lee Rannals for redOrbit.com - Your Universe Online NASA's Curiosity rover has proven some of the meteorites discovered have indeed come from the Red Planet, according to a new study published by the American Geophysical Union. A new measurement of Mars' atmosphere by Curiosity's Sample Analysis at Mars (SAM) instrument shows two forms of argon gas. The lighter and heavier forms, or isotopes, of argon exist naturally throughout...

Martian Meteorite Age Puzzle Solved
2013-07-25 04:47:27

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Occasionally, a meteorite is found on Earth with peculiar origin: Mars. Anytime a large object such as an asteroid or comet impacts the surface of Mars, chunks of rock are ejected into outer space. Over time, some of these stones will make their way to Earth, impacting the ground as meteorites. We know that these specimens are from Mars based on their composition and other factors. So they provide an excellent laboratory for...

Mars May Have Had Oxygen Atmosphere Four Billion Years Ago
2013-06-19 19:49:24

Lee Rannals for redOrbit.com — Your Universe Online Oxford University scientists reported in the journal Nature that Mars may have had an oxygen-rich atmosphere four billion years ago. The team examined differences between Martian meteorites and surface rocks examined by NASA's Spirit rover in the Gusev crater on Mars. Surface rocks are five times richer in nickel than the meteorites, which created some mystery for scientists as to whether the meteorites are typical volcanic...

Martian Meteorite Has Building Block Of Life
2013-06-12 11:41:42

Rebekah Eliason for redOrbit.com - Your Universe Online A Martian meteorite discovered in Antarctica was found to contain some of the early building blocks of life. The Antarctic Search for Meteorites (ANSMET) team discovered that this meteorite was clearly of Martian origin during its 2009-2010 field season. Contamination from the earth was ruled out and the meteorite was sent to the University of Hawaii at Manoa NASA Astrobiology Institute (UHNAI) for further study. The findings from...

Secrets To Life On Mars Could Be Revealed With Meteorite Studies
2013-05-02 14:56:21

Alan McStravick for redOrbit.com - Your Universe Online Currently, if scientists want to study meteorites that had originated from the red planet, they have to rely upon celestial travelers that arrived on this planet so long ago they now possess characteristics that tell of their time on Earth. This masks most clues that might offer information about the meteorites' time on Mars. However, a team of scientists has examined a meteorite that formed on Mars more than a billion years ago in...

NASA Curiosity Finds Evidence Of Atmosphere Thinning On Mars
2013-04-08 11:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online NASA´s Curiosity rover has been busy searching for signs that life may have once existed on the Red Planet. In the eight months since NASA dropped the rover on Mars, it has made significant progress in the hunt for water and life. In the latest round of evidence pertaining to Mars´ past, new measurements from Curiosity point towards the sky. These measurements, which consisted of analysis of Argon atoms in the...

Sutter's Mill Meteorite Under The Microscope
2012-12-21 05:32:02

Lee Rannals for redOrbit.com - Your Universe Online A meteorite study has led scientists to believe that asteroid surfaces may be more complex than previously thought. Scientists from around the world have come together to work on a meteor analysis of the Sutter's Mill meteorite that fell down to Earth in April 2012. The scientists reported in the journal Science that this particular meteor is an unusual example from a rare group known as carbonaceous chondrites. Samples from this...
