(...)Once near Mars, Phobos-Grunt will launch a Chinese-made satellite into Martian orbit, then perform maneuvers before landing on the moon Phobos orbiting some 6,000 kilometers above the Martian surface. Once on the tiny 27-km by 19-km moon, the spacecraft will collect samples for return to Earth on a built-in rocket. “The Phobos-Grunt mission will be the next step toward accomplishing a full Mars sample return mission and is a dress rehearsal for it,” says Louis Friedman, executive Director of the Planetary Society, a space advocacy organization that he founded with the late Carl Sagan.
The Planetary Society supports plans for returning samples from Phobos for analysis and also has its own experiment on the Phobos-Grunt probe consisting of a capsule carrying the living interplanetary flight experiment (LIFE). “LIFE is a container resembling a hockey puck that is 56 mm in diameter and 18 mm thick and weighing about 100 grams,” Friedman says. “It will hold 30 small tubes, each 3 millimeters in diameter, of terrestrial microorganisms.” The experiment will test the survivability of these microbes during 34 months in space
“Between us and our European collaborators that include the Russian Academy of Sciences, Moscow State University, the American Type Culture Collection, and the Institute for Aerospace Medicine in Germany, we are sending three strains of Bacillus subtilis, Deinococcus radiodurans, Saccharomyces cerevisiae, seeds of Arabidopsis thaliana, Haloarcula marismortui, and tardigrades [microscopic, water-dwelling, segmented animals known as water bears], each in triplicate to obtain better science results,” says David Warmflash, a member of the Planetary Society and an associate with the National Astrobiology Institute and National Aeronautics and Space Administration (NASA) Johnson Space Center in Houston, Tex. “We have included representatives of the three domains of life on Earth: bacteria, eukaryota, and archaea(...)”

Bacilli are an extremely diverse group of bacteria that include both the causative agent of anthrax (Bacillus anthracis)

D. radiodurans is capable of withstanding an acute dose of 5,000 Gy of ionizing radiation with almost no loss of viability, and an acute dose of 15,000 Gy with 37% viability.[9][10][11] A dose of 5,000 Gy is estimated to introduce several hundred double-strand breaks (DSBs) into the organism's DNA (~0.005 DSB/Gy/Mbp (haploid genome)). For comparison, a chest X-ray or Apollo mission involves about 1 mGy, 5 Gy can kill a human, 200-800 Gy will kill E. coli, and over 4,000 Gy will kill the radiation-resistant tardigrade.

Recent evidence indicates the involvement of S. cerevisiae in a range of superficial and systemic diseases. Numerous cases of S. cerevisiae-induced vaginitis have been documented as have cases of oropharyngeal infection. Potentially fatal systemic disease due to S. cerevisiae has been recorded in bone marrow transplant patients and in those immunocompromised as a result of cancer or AIDS. A number of studies have indicated that commercially available strains of S. cerevisiae may cause disease in certain individuals.

ASCA are consistently higher in frequency in Crohn's disease. Yeast cause a three-fold increase in lymphocyte proliferation relative to normal controls.[19] The ASCA antibodies are also more frequently found in familial Crohn's disease.

You know water is deadly if used inappropriately?
Bacillus subtilis is found in soil and used in laundry detergent. Also makes for a good treatment for urinary tract disease.
Saccharomyces cerevisiae is a yeast...need I say more?
So, unless the Russians are looking to make some bread or sort out the martians urinary tract issues, how does a hockey puck sized object pose ANY threat to Mars OR Earth?
And we can scratch Mars now, since it's stuck in earth's orbit...So, how will this supersonicbombhockey puck loaded withtoxic fuellaundry detergent andcausative agents of several diseasesyeast harm us again?

Guys, you do realize that those bacteria are now in space where various radiation flows occur? Those bacteria organisms going trough gene mutation as we speak.
I do remember NASA was saying, that in general observations those mutations make bacteria / organisms 10 - 100x times stronger...
So indeed, rapture is nearedit on 2011.11.11 by amfis because:
The mission involved a study lead by Arizona State University biologist Cheryl Nickerson that shows spaceflight affects the strength of salmonella, a germ that causes diarrhea and food poisoning. "Most of us have experienced a salmonella food borne infection, and it's not pleasant," Nickerson says.
While the shuttle orbited Earth, one of the astronauts turned a crank on a special canister. This mixed the bacteria with some food so that they started to grow. Then the shuttle headed home.
"These samples were recovered incredibly quickly off of the shuttle upon landing," Nickerson says.
Stronger, Faster Bacteria Within a couple of hours, before the bacteria could readjust to life on Earth, the scientists used them to infect mice. These mice ended up doing much worse than animals infected with bacteria grown on earth. "They got sick quicker and they ultimately succumbed to the infection quicker," Nickerson says. This is the first time anyone has shown that bacteria can become more dangerous after spaceflight, Nickerson says. Previous studies had shown that some bacteria grow faster in space, or seem better able to resist antibiotics.
