Unleash the MAHLI!

Ah! That’s better! Curiosity can see clearly through its robotic arm-mounted Mars Hand Lens Imager (MAHLI) for the first time since landing on Mars on Aug. 5.

Although the dust cap has been in place up until now, the camera was used to grab Curiosity’s first fuzzy color landscape pic and, only last night, it was used to snap a fuzzy “self portrait” of Curiosity’s “head” — but that was achieved by looking through the semi-transparent dust cap still attached to the lens. Today, the very first crystal-clear “open” MAHLI image has been acquired after mission controllers sent the command for the re-closable dust cap to swing open. The picture shows a patch of Mars dirt next to the rover measuring about 86 centimeters across. The large pebble at the bottom of the frame is about 8 cm wide.

This may be a very preliminary image, but the MSL team are already using it to do science. “Notice that the ground immediately around that pebble has less dust visible (more gravel exposed) than in other parts of the image,” says the image description on the MSL mission site. “The presence of the pebble may have affected the wind in a way that preferentially removes dust from the surface around it.”

Mars pebble science FTW!
