The Battle for Biodiversity: Monsanto and Farmers Clash - Anna Lappé - Life
Time is running out for NASA's stuck Mars rover Spirit as engineers prepare to make their final attempts to rescue the hard-luck robot from its Martian sand trap. Spirit spun its wheels extremely slowly Tuesday in yet another attempt to extricate itself from the wheel-deep sand it has been stuck in since May 2009. Engineers are studying the results of that drive to decide which of the few remaining options to try next. So far, nothing NASA has tried has worked to free Spirit . "Earlier drives in the past two weeks using wheel wiggles and slow wheel rotation produced only negligible progress toward extricating Spirit," NASA officials said in an update.
