I guess the larger question is "Why?" Why are they even looking for this in the first place?
Imagine if all the money spent on sending handfuls of people into space was spent on health care education here on Earth? I love the idea of astronomers at their telescopes but the costs involved with manned spaceflight is astronomical. Didn't it cost something like $10,000/pound to send stuff up in into orbit in the shuttles? How much are the Mars landers costing?
We need a SOLID health research plan back here on Earth. Far less money for the Big Pharma-controlled 'sickness industry' of today and more for alternative medicine research. Alternative medicine has been shown time and again to be just as, or more, effective than Big Pharma drugs or a surgeon's butcher knives. This is actually a timely discussion as the Big Pharma made up "flu season" is coming fast.
For example, did you know the flu shots are ineffective and even dangerous? If you start to show the signs of a flu there are simple things you can do. A homeopathic remedy of Oscillococcinum along with Chiropractic adjustments form a two-pronged attack on the flu virus. The Oscillococcinum attacks the young viruses while the adjustments to the spine help the body's innate healing capabilities destroy the mature virus. It's a 100% painless and safe way to heal yourself from within with the human body's most powerful weapon: innate intelligence.
Don't just take my word for it, educate yourself with the University of Google! Here's more evidence of efficacy:
