CheMin's examination of Rocknest samples found the composition is about half common volcanic minerals and half non-crystalline materials such as glass. SAM added information about ingredients present in much lower concentrations and about ratios of isotopes. Isotopes are different forms of the same element and can provide clues about environmental changes. The water seen by SAM does not mean the drift was wet. Water molecules bound to grains of sand or dust are not unusual, but the quantity seen was higher than anticipated.

Didn’t they “discover” fossilized bacteria on Mars a few years back? Haven’t heard much of it lately.

Was there a launch today? My husband saw a trail going up around 5pm EST. The launches from the Cape are usually to the east between 2-3 o’clock. This was a trail visible from the southwest in Orlando at about 6-7 o’clock around 5PM.

If they have found life, obama will want to tax the top three percent to redistribute to the scum and bacteria.

How do we know that the organic compounds which have been detected in soil samples taken by the Mars experiment aren’t the result of the possible contamination of the Mars Curiosity vehicle before it left Earth?

They just need to discover global warming on Mars to get more funding.

chlorine is a deadly chemical.

sulfur is common where anything has volcanic activity.

we already knew mars has water, frozen, on it.

So...what became of the two low budget rovers that were all over the news a couple of years ago?

organic compounds (chemicals containing carbon)

lol, "organic compounds" vs "chemicals containing carbon"...maybe they mean the same thing to chemists, but to a layman one sounds like "life" and the other like "yeah whatever".
