LOS ANGELES (AP) -- The Mars rover Curiosity is humming again, after being sidelined by back-to-back computer problems.
The six-wheel rover fired up its onboard laboratories, and analyzed a pinch of rock dust over the weekend. It had been unable to do science experiments since late last month, after experiencing a computer memory problem.
Mission managers say Curiosity will work for a week before it takes another break -- this time planned -- because the sun will block communications between Earth and Mars.
Before the computer woes, Curiosity drilled into a rock, tested the powder, and found it contained some of the chemical ingredients necessary for microbial life. There are plans to drill into another rock before setting off for a mountain later this year.
