NASA's Mars rover Curiosity has found some more bright stuff on the Red Planet, scientists say.
The Curiosity rover had dumped out a recent sample of Mars dirt after spotting shiny particles inside the hole dug by the shovel-like scoop on its robotic arm. Mission scientists were concerned that the bright material might be debris from the rover itself, so they ordered Curiosity to toss the Mars sample as a safety precaution, mission managers said in a statement.
As it turns out, the bright particles are actual Martian in origin, they added.
Curiosity is scooping up Mars dirt in a spot called "Rocknest" in preparation to deliver the first samples to a pair of instruments on its car-size body. The rover scooped its first Mars sample on Oct. 7, but further work was delayed when the rover's cameras spotted a bright object —likely a piece of plastic —on the ground in the area.

"Other small pieces of bright material in the Rocknest area have been assessed as debris from the spacecraft," NASA officials said in a statement Monday (Oct. 15). "The science team did not want to put spacecraft material into the rover's sample-processing mechanisms."
A new review of the latest bright material suggested it is actually a Mars phenomenon, and not litter from Curiosity. With that analysis in hand, rover scientists cleared Curiosity to take a third scoopful of Mars dirt.
"Confidence for going ahead with the third scooping was based on new assessment that other bright particles in the area are native Martian material," NASA officials said. "One factor in that consideration is seeing some bright particles embedded in clods of Martian soil."
Curiosity's third scoop of Mars dirt will be the first sample to actually be processed by the rover's Chemistry and Mineralogy instrument, known as CheMin. A later Mars sample will be scooped up and deposited inside the rover's Sample Analysis at Mars, or SAM, instrument.
The CheMin and SAM tools are two of the core instruments on Curiosity designed to determine if Mars may have once been habitable for microbial life.
