Submission + - Send a name to Mars for Christmas

space_elf writes: The Planetary Society has an interesting program just in time for Christmas, and just perfect for the persnickity someone in your life who seems to have everything. You can submit a name that will be written on a mini-disk and flown aboard the upcoming Phoenix mission to Mars. Included in the free (as in beer) service is a certificate to present to them as proof of their name going into space. Sorry folks, mothers-in-law are not allowed.

Submission + - Taking GPS underwater

Jonathan Fogg writes: "The local BBC channel here in the UK is reporting that Node, a mobile media company, are making a specialist version of their device for deep underwater use. The product seems to be targeted at scuba divers and the many people who enjoy snorkling etc. with a view to guiding them to, and around, the many amazing underwater sites in the world.

Their technical researchers have been demoing it on a wreck off the south west coast of the UK. It uses GPS to help you navigate around the wreck, whilst triggering various media and information that relates to the site — all whilst your 35 meters underwater.

It got me wonder whether there were actually any Divers out there who would be interested in using such a specialist device, and whether the explosion of specialist gadgets like this one has once and for all proved that the convergence theory is codswallop?"
