There are some pictures that just grab your attention - and this is one of them. Tracy Caldwell Dyson recently spent six months board the ISS (International Space Station) as a NASA astronaut. A chemist by training, she is a Ph.D and has been working at Nasa in a variety of roles including working with the Russian Federal Space Agency. She has been up in a shuttle before (Endeavour) back in 2007.
Yet we think it quite likely that this is the picture she will show her grandchildren in the future - it quite simplt stunning. There recently completed viewing window opens up the earth for Ms Caldwell Dyson and thanks to photography we get to see what she saw (in a way!). Fantastic.
