If Curiosity locates H2O, a simmering NASA controversy will boil over. The rover's drill bits may be tainted with Earth microbes that could survive upon touching water.
By Louis Sahagun, Los Angeles Times
For all the hopes NASA has pinned on the rover it deposited on Mars last month, one wish has gone unspoken: Please don't find water.
But if by chance the rover Curiosity does find H2O, a controversy that has simmered at NASA for nearly a year will burst into the open. Curiosity's drill bits may be contaminated with Earth microbes. If they are, and if those bits touch water, the organisms could survive. The possible contamination of the drill bits occurred six months before the rover's launch last Nov. 26 ...
About 250,000 bacterial spores throughout Curiosity are assumed to have survived the landing, officials said. Nearly all of them are believed to have perished within minutes of exposure to the harsh Martian conditions in Gale Crater freezing temperatures, intense ultraviolet radiation and an atmosphere of mostly carbon dioxide.
But scientists have learned in recent years that some Earth life forms can live in space and in at least some of the conditions found on Mars. The European Space Agency discovered that lichens launched on a Russian Soyuz rocket in 2005 survived several days of full exposure to the vacuum of space and ultraviolet and cosmic radiation. ...

The Earth will survive long after we are gone, at least until the sun explodes and destroys all life...
and at that point nothing we've done or haven't done matters.

(10,618 posts)...they would just put some kind of undetectable contraceptive gas into the atmosphere and wait 75 years for humans to die out. Stealthy. No need for open invasion. No casualties on their side. Low cost for them. And humans wouldn't have a clue that the aliens even existed, let alone that they had successfully invaded earth.

(8,830 posts)The majority of the article talks about how the drill bit (and Curiosity) could be contaminated with hundreds of thousands of microbes - to the point that it shouldn't be allowed to get near water or ice because the microbes might have survived the launch, the trip, and the conditions on the planet.
Then, toward the end, it discusses Curiosity's next mission - to drill into a rock at Glenelg Intrigue. It says:
Note that last sentence. Dr. Conley - the Planetary Protection Officer who was not consulted about mounting the drill bit and so changed the mission to keep Curiosity away from ice and water (by the way - I totally love that title) - says that she is unconcerned about the experiment contaminating the site because "any surviving organisms will die swiftly."
Okay . . . so why the hand-wringing about possibly drilling into the ground and hitting water? It sounds like the microbes are doomed anyway.
I'm confused!

(20,135 posts)they won't survive long...unless they are introduced to water, in which case they could potentially survive and thrive in the water. If they aren't exposed to water they will die off.
That drilling at Glenelg Intrigue isn't scheduled for another month.

(8,830 posts)it be reasonable to deliberately drill some rocks first and kill the bacteria? Are they one use only drills?
I know I'm over-simplifying; it just seems like there should be a more sensible solution than "don't go near the water/ice" (assuming Curiosity finds it).

http://www.marsanomalyresearch.com/The most obvious thing he noticed (and anyone w photoshop experience can see once it's pointed out) is the vast computerized tampering on the official images released to the public. In fact he's pretty bitterly obsessed about the tampering.
But there's so much data, occasionally they miss things. Now those "misses" are interesting indeed.
such as this:
http://www.marsanomalyresearch.com/evidence-reports/2012/221/real-mars.htm
I'm open minded, but I suppose this info is hard to swallow. I expect the usual forum skeptics to pounce on me and rip Skipper's site to shreds.
I just think it's interesting, and more research needs to be done.
On edit:
thanks for the correction on Skipper's background

(34,845 posts)Each time they think they find something, it's never incontrovertible proof so another mission is planned.
We have a fucking tin can in orbit about Earth doing 'experiments' and yet another attempt to prove -really, REALLY prove this time- that life exists on Mars.
I am sick to death of the half-assed 'adventures' we have had to endure. If they can't get the fucking proof with robots, it's time to send a team of humans.

Remember this day fellow earthicans we threw the first punch and we did it with a small car sized robot and dirty drill bits.
