1909 VDB LINCOLN CENT STILL GATHERING DUST ON MARS

Kavan Ratnatunga submitted this update on the 1909 VDB Lincoln cent gathering dust on the planet Mars. -Editor

Mars 1909 cent after

This image of a U.S. penny on a calibration target was taken by the Mars Hand Lens Imager (MAHLI) aboard NASA's Curiosity rover in Gale Crater on Mars. At 14 micrometers per pixel, this is the highest-resolution image that MAHLI can acquire.

This image was obtained as part of a test on the 411th Martian day, or sol, of the mission (Oct. 2, 2013), the first time the rover's robotic arm placed MAHLI close enough to a target to obtain the camera's highest-possible resolution. It shows that, during the penny's 14 months (so far) on Mars, it has accumulated Martian dust and clumps of dust, despite its vertical mounting position on the calibration target for MAHLI.

This United States penny from 1909 is part of a series of markings and objects meant to help calibrate the cameras that Curiosity is equipped with.
