European scientists build proving ground for Mars rovers

The 'Mars Yard' in Stevenage, England, is designed to help the European Space Agency develop a rover for its ExoMars program.

It looks like a giant sandbox — except the sand has a reddish tint and the "toys" on display are very expensive prototypes designed to withstand the rigors of landing on Mars.

The European Mars rover unveiled Thursday at a "Mars Yard" testing ground in Britain is designed to drill beneath the surface of the Red Planet searching for signs of life. It's been dubbed 'Bryan' by its creators — earlier versions were named Bridget (clad in gold material that makes it look like a garish dune buggy) and Bruno.

The plan is to develop an autonomous robotic vehicle that can be launched in 2018 as part of the European Space Agency's ExoMars program, an ambitious plan that begins in 2016 with the launch of a Mars orbiter and demonstrator landing module.

The goal is to bring samples of Mars back to Earth by the 2020s.

The rovers being developed at the Airbus Defense and Space facility will be able to drill for samples and "feed" them into an onboard laboratory. The information gleaned can then be sent back to Earth.

The data transmissions could even contain proof that living organisms on Mars had been found, said Abbie Hutty, an engineer charged with helping to make the rover tough enough. The rover's drill is designed to penetrate two meters (six feet) beneath the surface, probing an area shielded from radiation and containing water deposits.

"If there was life, that's where we would expect to find it," she said.

The rover will be in communication with controllers on Earth twice a day and be able to use transmitted information to navigate to new destinations on Mars. It has a complex navigation system that relies on a pair of cameras mounted on a mast. These map the safest and fastest navigation route, determining which rocks the rover can handle and which must be avoided.

But the rover won't be fast — its maximum range is about 70 meters (210 feet) per day.

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.”

If you’re looking for bran muffin journalism, you can subscribe to the Monitor for $15. You’ll get the Monitor Weekly magazine, the Monitor Daily email, and unlimited access to CSMonitor.com.
