Building Blocks of Life Found on Mars

What has Nasa found on Mars? Alien life? Watch announcement livestream here

According to NASA, billions of years ago a water lake inside Gale Crater held ingredients necessary for life, data from the rover reveals. He points out carbon-rich meteorites and dust could generate the reported amounts of methane as they fell into the Martian atmosphere, and that the year-to-year periodicity is not wholly consistent with the timing of the Martian seasons.

Big news from Mars today: NASA's Curiosity rover found ancient traces of organic matter embedded in Martian rocks and detected a "seasonal variation" in atmospheric methane on the Red Planet - an annual pulse of the gas, nearly as if something out there were breathing.

"It's incredibly exciting, because it shows that Mars is an active planet today", says Caltech planetary scientist Bethany Ehlmann, a Mars expert who wasn't involved with the studies. So the Martian traces of organic matter do hint that the basic conditions for life to form were present on Mars at around the same time they existed on Earth.

"All sorts of big questions could be answered by finding life on Mars or by not finding life on Mars", says David Weintraub, a professor of astronomy at Vanderbilt University in Nashville and author of the book "Life on Mars: What to Know Before We Go". The 96-mile crater, named for Australian astronomer Walter F. Gale, was most likely formed by meteor impact between 3.5 to 3.8 billion years ago.

In 2013, it confirmed organic compounds in rocks in a deep part of the crater called Yellowknife Bay, said Jennifer Eigenbrode, who led the organic molecule study published in Science.

As promised, NASA has announced new milestone Mars discoveries, namely the presence of organic molecules and seasonal changes in atmospheric methane. The Martian surface is bombarded with radiation that can degrade organic compounds, explains Eigenbrode. Instead, SAM detected fragments of much larger molecules that had been broken up during the high-temperature heating experiment.

That sparked a breakdown of the coalition's first attempt to form a government and a furious reaction from the coalition leaders. They have also proposed plans to cut taxes, scrap a previously agreed pension plan, and institute a "universal basic income".

Then she looked at the analyzer results again.

The samples were heated to 500C in Curiosity's oven to release any organic molecules, the kind that don't vaporise easily. Curiosity sampled mudstone in the top 5 centimeters from the Mojave and Confidence Hills localities within Gale Crater. The methane, he and his colleagues speculate, could come from aquifers melting during the Martian summer, releasing water that flows over rocks deep underground to produce fresh gas.

A potential explanation for the seasonal Martian methane.

Inclusion of carbon dioxide in the mix could potentially lower the pressures required to form these lattices, allowing methane clathrates to form just a few metres below the surface. That could even be happening beneath the surface now, the researchers said.

The second paper investigates a problem that has been disturbing Mars scientists for several years: the abundance of methane in Mars' atmosphere. And the Mars 2020 rover, which is expected to launch July 2020, may be able to assist with one day retrieving soil samples from Mars. "The first one would be life, which we don't know about".

Another team of scientists, led by Christopher Webster from the California Institute of Technology, presented evidence that methane concentrations detected on Mars follow strong seasonal variations.
