1909 V.D.B. Lincoln Cent on NASA’s Mars Rover Curiosity

NASA’s Mars rover Curiosity has taken the first photographs of a camera calibration target that actually includes a classic United States coin. Found in the target is a 1909 V.D.B. Lincoln cent.

1909 Lincoln Cent on Mars rover Curiosity

The Lincoln cent in this image is part of a camera calibration target on NASA’s Mars rover Curiosity. The Mars Hand Lens Imager (MAHLI) camera on the rover took this and other images of the MAHLI calibration target during the 34th Martian day, or sol, of Curiosity’s work on Mars (Sept. 9, 2012).

The century old coin and other calibration devices are used by Curiosity’s Mars Hand Lens Imager ( MAHLI) to test its performance. MAHLI is capable of focusing on objects as close as 2.1 centimeters up to infinity.

The choice to include the Lincoln cent was the recommendation of MAHLI’s principal investigator, Ken Edgett.

"The penny is on the MAHLI calibration target as a tip of the hat to geologists’ informal practice of placing a coin or other object of known scale in their photographs. A more formal practice is to use an object with scale marked in millimeters, centimeters or meters," Edgett said. "Of course, this penny can’t be moved around and placed in MAHLI images; it stays affixed to the rover."

This specific coin was actually purchased by Edgett for use on Mars rover Curiosity. He chose the 1909 V.D.B. Lincoln Cent originally because the rover was due to launch in 2009, the centennial of the Lincoln Cent. Delays would force the launch back to 2011, but the choice to still use the same coin remained as its specifications had already been committed to.

Lincoln Cents made their first appearance in 1909 as part of a 100th anniversary celebration of the birth of the 16th President of the United States, Abraham Lincoln. The original Lincoln cent design was the work of artist Victor David Brenner whose initials (V.D.B.) originally appear on the reverse of the coin.

"Everyone in the United States can recognize the penny and immediately know how big it is, and can compare that with the rover hardware and Mars materials in the same image," stated Edgett. "The public can watch for changes in the penny over the long term on Mars. Will it change color? Will it corrode? Will it get pitted by windblown sand?"

Coins have been used previously on NASA missions as part of other instrument packages. However, this marks the first time that one will be monitored for changes as it is subjected to the conditions of the surface of another planet.

Mars rover Curiosity launched at 7:02 a.m. PST on November 26, 2011. The ten-foot long rover was designed to "search areas of Mars for past or present conditions favorable for life, and conditions capable of preserving a record of life," according to NASA.

It most certainly cannot be determined that this a V.D.B cent as those intitials are on the reverse.

Let’s hope a Martian does not steal this valuable coin!

This will give future archaeologists fits trying to figure out when humans actually landed equipment on Mars. 1909? Amazing that they were that advanced back then!

Had we listened and followed TESLA instead of cowing to Edison and BIG BANKING… we WOULD have been that advanced back then.

I listened to Tesla some in college, they did a great unplugged cover of “Sign, sign, every where a sign”

I listened, and followed Tesla, back in the 80’s šŸ™‚

Too bad it’s not an “S” !

>Penny made in 1909
>first Lincoln penny made in 1909 by V.D.B
>coin has Lincoln on it
>99.999999999999999% chance of it being a V.D.B Penny

They have to get that penny certified. It will pay for their next moon landing.

You guys are just about to crack me up šŸ™‚

Maybe they are expecting to find a parking meter…????

CAmeron, even if that conspiracy theory were true the time range for that would be ridiculously short, you think we could go from the AC motor to landing on Mars in just 20 years? Quite a few other things needed to be invented besides that. in 1893 Tesla was still only theorizing about using radiowaves for communication -theorizing.

His main gig was electricity, he did diddily squat in anything related to jet fuel. Tesla, you could call him both the most underrated and the most overblown scientist in history.

Marvin plans to sell it so he can finance the latest enhancements to his P-U 235 Space Demodulatorrrrr.

Knock, knock, knock…Penny.
Knock, knock, knock…Penny.
