Mars rover Curiosity's arm wields camera well

Sep 11, 2012
This view of the lower front and underbelly areas of NASA's Mars rover Curiosity combines nine images taken by the rover's Mars Hand Lens Imager (MAHLI) during the 34th Martian day, or sol, of Curiosity's work on Mars (Sept. 9, 2012). Curiosity's front Hazard-Avoidance cameras appear as a set of four blue eyes at the top center of the portrait. Fine-grain Martian dust can be seen adhering to the wheels, which are about 16 inches (40 centimeters) wide and 20 inches (50 centimeters) in diameter. The bottom of the rover is about 26 inches (66 centimeters) above the ground. On the horizon at the right is a portion of Mount Sharp, with dark dunes at its base.

(Phys.org)—NASA's Mars rover Curiosity stepped through activities on Sept. 7, 8 and 9 designed to check and characterize precision movements by the rover's robotic arm and use of tools on the arm.

The activities confirmed good health and usefulness of Hand Lens Imager, or MAHLI, and used that camera to check placement during several positioning activities. 

MAHLI took an image with its reclosable dust cover open for the first time on Mars, confirming sharp imaging capability that had been obscured by a thin film of dust on the cover during previous use of the camera. It took images of cameras at the top of Curiosity's mast, of the underbelly of the rover and of MAHLI's own calibration target, among other pointings.

"Wow, seeing these images after all the tremendous hard work that has gone into making them possible is a profoundly emotional moment," said MAHLI Principal Investigator Ken Edgett of Malin Space Science Systems, San Diego. "It is so exciting to see the camera returning beautiful, sharp images from Mars."

The camera's calibration target includes a 1909 Lincoln penny that Edgett purchased for this purpose. "We're seeing the penny in the foreground and, looking past it, a setting I'm sure the people who minted these coins never imagined," Edgett said.

The penny is a nod to ' tradition of placing a coin or other object of known scale as a size reference in close-up photographs of rocks, and it gives the public a familiar object for perceiving size easily when it will be viewed by MAHLI on Mars.

"The folks who drive the rover's arm and turret have taken a 220-pound arm through some very complex tai chi, to center a penny in an image that's only a few centimeters across," said MAHLI Deputy Principal Investigator Aileen Yingst of the Tucson-based Planetary Science Institute. "They make the impossible look easy."

The arm characterization activities, including more imaging by MAHLI, will continue for a few days before Curiosity resumes driving toward a mid-term science destination area called Glenelg. In that area, the rover may use its scoop to collect a soil sample, and later its drill to collect a sample of powder from inside a rock.

Curiosity is five weeks into a two-year prime mission on Mars. It will use 10 science instruments to assess whether the selected study area ever has offered environmental conditions favorable for microbial life.

When are we going to see an HD video of another planet? I have seen millions of pictures, how about some movies with sound?

How about some Martians, or some ancient ruins? There are all sorts of great hoaxes, er.. I mean images of the mysterious red planet on the web.

Agreed, i wish they would have landed Curiosity on the outskirts of Valles Marineris so it can take a panorama postcard of its depths. I can't wait until IF Curiosity finds a clam shell fossil or something of the sort. That would be fascinating to say the least!

"The MastCams can take full-color 360-degree panoramic images by stitching together 150 individual photos taken in a slowly rotating circle. Finally, the cameras can also take 720p high-definition video at a rate of about 10 frames per second."
