the Mars Rover, the self-propelled, solar powered box o' sensors 'n stuff, the slow inches along the surface (and battles the violent environment) of the red planet may be a mainstay of space exploration, but it is certainly not the only way to get the job done. For example, the children at Draper Labs are - last seen in this room with its injectable Nano sensor - the process of development of vehicles leaving the (literally) traditional Rover in the dust. Draper hopper prototype is designed with an impeller drive system that is used to nitrogen, 25 miles in a few days or, preferably, a couple of hours cover it compressed. Comparison, NASA's spirit and opportunity craft have about twenty miles since early 2004 covered hit the surface of Mars. Of course the hoppers must bring fuel with you, so their life is cut dramatically shorter than your wheel-based contemporaries, but we always believed more autonomous vehicles should "live fast / die young," such as SID vicious or James Dean. With any luck, we should see to test flights by January 2011.

we heard over 1TB medium optical discs in the past but TDK has now revealed a 1 TB monster of own at CEATEC. In contrast to existing Blu-ray that most use four recording layers among, TDK's creation offers 16 layers on both sides of the disc, everyone can save up to 32 GB each. If you are the optical memory arms race track is that seven more gigabytes per layer as pioneer's achieved disc 400 GB and 500 GB back in 2008. TDK's prototype has the potential to use existing Blu-ray technologies because it already found consists of a material in the BD and the same beam aperture shares. On the down side shows the current version recording layers 260µm-, that more than twice as thick as its Blu-ray counterpart- and causes is aberrations in today's fat layer hate optical lenses. Outside of his biggest loser qualifications but says TDK "its commercialization of disc manufacturers depend on.", Considering, the company has still 10-layer-320 GB disks at CEATEC 2009 revealed to sell, we are, however, doubtful this 1 TB improvement shops is quickly taken.
