The Curiosity rover has been in an especially precarious position since late last week, when a memory glitch forced it into a safe mode while NASA prepared a backup and diagnosed the trouble. We're glad to report that the worst is over. Scientists have confirmed that the rover left safe mode on later on Saturday and started using its high-gain antenna for communication a day later. However, it's not quite out of the woods yet -- if Mars had woods, that is. The backup is still taking on the information it needs to assume full responsibility, and NASA wants to evaluate the suitability of the one-time primary computer as the new backup. Nonetheless, all the early indicators point to Martian exploration going back on track within days.
