Curiosity

NASA’s Curiosity rover has returned a stunning image of the sun dipping behind a distant ridge from a vista inside Mars’s Gale Crater, only the Martian sunset spectacle appears blue instead of the reddish hues seen on Earth.

Officials are assessing how to adjust operations to collect future rock core samples with NASA’s Curiosity Mars rover after identifying its drill as the likely source of a short circuit that stopped the rover’s movement in late February.

A short circuit that halted movement of NASA’s Curiosity Mars rover is not expected to keep the mobile robot stationary for long, but engineers want to know whether the problem will restrict some future science operations.
