Can you imagine....

....being twins, and identical ones at that, and later in life, both becoming Navy pilots, and then both becoming astronauts, and then, both going into space...and, until just recently it looked as though they would both be up there, together...it's too bad that won't happen(how cool those photos would have been when they embraced!), at least not in the near future...but, it's a great story nonetheless, and now, with the added, deeply emotional drama of Rep. Gabrielle Giffords, Mark Kelly's wife....anyway, I just find this a fascinating story.  And, here's Scott Kelly giving a quick tour of the space station.  And,  a poignant moment.
