Why is Barack Obama's signature on Mars?

Curiosity drops a few rather big names in recent images taken with its MAHLI camera.

Curiosity drops a few rather big names in recent images taken with its MAHLI (Mars Hand Lens Imager) camera: here we see a plaque affixed to its surface bearing the names and signatures of U.S. President Barack Obama, Vice President Joe Biden, Office of Science and Technology Director John Holdren, NASA Administrator Charles Bolden and other key figures responsible for making the Mars Exploration Program possible.

You never know… even on another planet it can’t hurt to have friends in high places!
 
The image was captured by MAHLI on September 19, the 44th sol of the MSL mission. (See the original raw downlink here.)

The rectangular plaque is made of anodized aluminum, measuring 3.94 inches (100 mm) high by 3.23 inches (82 mm) wide. It’s attached to the front left side of Curiosity’s deck with four bolts. (Explore Curiosity in 3D here.)

Dust, pebbles and variously-sized bits of Mars can be seen scattered around the plaque and deck, leftover detritus from the rover’s landing.

The complete list of signatures is:

Barack Obama, President, United States of America

Joe Biden, Vice President

John P. Holdren, Director, Office of Science and Technology Policy

Charles F. Bolden, Jr., Administrator, National Aeronautics and Space Administration

Edward J. Weiler, Associate Administrator, Science Mission Directorate (2008–2011)

James Green, Director, Planetary Sciences Division

Doug McCuistion, Director, Mars Exploration Program

Michael Meyer, Program Scientist, Mars Exploration Program

David Lavery, Program Executive, Mars Science Laboratory

In another image taken on the same sol, Curiosity shows some national pride with a circular medallion decorated with the stars and stripes of the American flag. The 68-mm-wide circular aluminum plate is affixed to one of the rover’s rocker arms. It’s just one of its four “mobility logos” — the others having the NASA logo, the JPL logo and the Curiosity mission logo.

The main purpose of Curiosity’s MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover’s Gale Crater field site. Developed for NASA by Malin Space Science Systems in San Diego, CA, the camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity, providing versatility for other uses, such as views of the rover itself from different angles.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”
