For the telomere study, the most surprising and unexpected finding was that he had longer telomeres in space - exactly the opposite of what we imagined. Susan Bailey

Since the twins are as identical as it gets, we are expecting to find things specific to space flight. We will be able to compare the twins to each other - and to other related astronauts, hopefully at least 10 others to get significant results.

I can eat lots of tacos!

Hard enough to find twin astronauts, much less triplets..

Will do!

Mark Kelly is willing to do just so much for the sake of science. For example he will not be eating the same food as Scott does in space. Mark will be giving blood samples taken at about the same times as Scott. For our study, we expect to see accelerated telomere shortening and elevated telomerase activity, both of which may contribute to aging and or disease.

I like those nicknames!
