It's been less than a year since it went live, but Clearwire has now officially dropped its Rover pre-paid WiMAX service, saying that it was simply a way to "test some new pay-as-you-go pricing options and was offered on a limited retail basis in a couple markets." As you may recall, the brand offered just two products -- the Rover Puck WiFi hotspot and a USB stick -- and it gave customers the ability to purchase 4G WiMAX service on a daily, weekly or monthly basis starting at just $5 a day. As a Clearwire spokesperson explains to  FierceWireless , however, the company is not giving up on pre-paid options altogether, and says that it's own new no-contract plans "should meet the needs of most of the Rover customer base."

Sending a rover to a distant planet is no small feat, so we might as well make the landing even more spectacular, right? That's exactly what NASA has in mind for its  Curiosity  Mars rover, albeit for more practical reasons. Launching in late 2011 and expected to land on Mars in August 2012, this mobile laboratory will see a unique descent after entering the Martian atmosphere: there'll be the usual separation from the heatshield and backshell, but at about 380 seconds into the entry, the rover will be gently lowered down by wire from a "sky crane," as opposed to taking a leap of faith. Once the landing is complete, the hovering sky crane will then detach from the rover and fly off for a dramatic disposal -- let's just hope it won't hit the now-dormant  Spirit .
