Organics found on mars!!!

I don't think the general public will accept it until they see a microscopic image of an organism. Either intact or fossilized.

Organics do not equal life. The average person might not know that, but the average person doesn't need to.

The scientists working on/with Curiosity, on the other hand...

Off topic: That was scary! I clicked on the thread when it was in The Space Lounge, and then it got moved Freaky!

On-topic: I think it's an interesting thing. It means that they can either form there, or can be made there, or came from somewhere else.... Which means it's interesting to say the least.

Correct me if I'm wrong but wouldn't large organic molecules not be large if they were constantly pelted with ionizing radiation?

Doesn't that mean that the molecules created would have to have been created recently?

There are small organics, such as glucose. Others exist, but I have no idea what they're called.

Water on Mars? Yay! Odd how we found organic compounds on a comet... before mars. I know it doesn't mean life it's still interesting.

EDIT: Wait, this is from a leak of some fluid? And the comet lander crash landed in the wrong place? Both were accidents... We should mess up more often.:wink:

Depends which ones. Some can survive, some can not. Ionizing radiation in Martian case works more indirectly, by "priming" the ground and making it pretty darn oxidative.

Is this new stuff? I thought JPL announced last December that Curiosity's SAM experiment had detected chlorobenzene, dichloroethane, dichloropropane, and dichlorobutane.

Yea... this sort of stuff is found in space... comets, nebula, etc.

Guess what... Titan has seas of organics...

Don't overreact.

Wake me when they find long polymers, and not just a subunit of a subunit of a molecule that would indicate life - such as a protein- ie a complex polymer of amino acids, or strands of DNA/RNA... ie polymers of bases composed of a sugar linked to a nucleic acid... the nucleic acid itself having cyclic hydrocarbon rings... simply finding cyclic hydrocarbon rings like benzene is a long way from finding life.

Organic molecules are building blocks of the life. When you find a bunch of bricks on the ground, usually it's a good indicator a building is somewhere nearby. Or was in the past. :)

As much as i believe there either is or was some life on mars - organic compounds are like finding clay, not bricks. Bricks would be RNA/DNA.
