Welcome to Once and Future Science

Welcome to Once and Future Science, where I’ll be blogging about scientific & technological advances in general, and advances in space science, medicine and energy in particular.

I’m Dr Jon Overton – you might be familiar with my space science series Ultra Frontier Explorer (that I produce for www.alwaysaround.net ) – you can catch up on UFEx here: https://www.youtube.com/playlist?list=PLtHji6t6ST4TMSidaU3SGEE1NSNI_QrHE

The background image I’ve used above is “The Day The Earth Smiled” which is an amazing composite photograph of Saturn, its rings and moons, with some planets of the Inner Solar System in the background. The Earth, as seen from 898million miles away (on Sat 19th July 2013) appears as the Pale Blue Dot in the lower right of the image. This image was produced by NASA’s Cassini mission, and is public domain, credit: NASA/JPL. You can see annotated and larger versions of this image here: http://www.nasa.gov/mission_pages/cassini/multimedia/jpl/pia17172.html#.VjVW8qe6tH0
