NASA's Mars rover Curiosity is back in action after being sidelined by a computer glitch for the second time in three weeks. <\/p>\n
Curiosity went into a precautionary \"safe mode\" on Sunday (March 16), apparently because a file slated for deletion was connected to one still in use by the rover. But the mission team has now sorted things out and returned the robot to active status, NASA officials announced today (March 19). <\/p>\n
The car-size Curiosity rover has not resumed science operations yet, however. It's still recovering from a separate memory glitch that knocked out its main, or A-side, computer in late February. Engineers swapped Curiosity over to its backup (B-side) computer at the time, spurring the rover to go into safe mode on Feb. 28. <\/p>\n

Mission engineers continue to configure and check out the B-side computer, which remains the Curiosity rover's active computer. The A-side is now available as a backup if needed, officials said. <\/p>\n
All of this drama has delayed Curiosity's activities at a Martian site called Yellowknife Bay, which mission scientists announced last week could have supported microbial life. <\/p>\n
This discovery was based on Curiosity's study of material pulled out of a hole it drilled last month into a Yellowknife Bay rock. Further such analytical work should be possible soon, rover team members said. <\/p>\n
\"We expect to get back to sample-analysis science by the end of the week,\" Curiosity mission manager Jennifer Trosper, of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement. <\/p>\n
The rover team also wants to drill another hole in the Yellowknife Bay area to confirm and extend their previous observations. But this won't happen until May, partly because of an upcoming unfavorable planetary alignment. <\/p>\n
Engineers won't send commands to the six-wheeled robot for most of April, because Mars and Earth will be on opposite sides of the sun during this time. <\/p>\n
