This particular "journey" may not involve any humans descending into the Earth, but that doesn't mean it isn't still plenty ambitious -- a pair of scientists are now proposing to drill to the Earth's mantle and bring back some samples, effectively picking up where the first attempt to do so left off some fifty years ago. Of course, the key word here is "proposing," but the scientists, Damon Teagle and BenoƮt Ildefonse, say that we now have the technology and knowledge necessary to do so, and that drilling could begin by 2020 if everything goes as planned. They're looking to get things underway well before that, however, and are already planning an expedition in the Pacific as soon as next month where they say they will "bore further into the oceanic crust than ever before."
Pentax's Optio WG-1 GPS point-and-shoot satisfied geotaggers out of the box, but owners of its K-5, K-r and 645D DSLRs have had to make do with third-party taggers like the PhotoTrackr or Eye-Fi. The new hotshoe-mounted O-GPS1 module fixes that oversight by recording latitude, longitude, altitude, Coordinated Universal Time and shooting angle. Everyday snappers might find an extra hotshoe attachment cumbersome, but astro-photography enthusiasts could well be enticed by the device's interesting "ASTROTRACER" function. This helps you take clearer photos of celestial bodies by using the in-built sensors to calculate a star's movement and then employing the camera's shake reduction system to compensate. Sounds clever, but be advised: this module is only for Pentax DSLRs -- and only for very specific models at that. You'll get full functionality with the K-5 and K-r cameras, and geotagging (no ASTROTRACER) with the 645D. Oh, and you'll need to make sure yo
