This Video Lets You Fly Over The Surface Of Mars
To celebrate 10 years of images from the European Space Agency's Mars Express orbiter, the German Aerospace Center has compiled a video that gives sweeping digital views of the planet's landscape.

What's the Latest Development?
In the summer of 2003, the European Space Agency (ESA) launched a mission to explore the surface of Mars from orbit as well as on the ground. While the rover, Beagle 2, stopped communicating shortly after leaving the orbiter, that orbiter, Mars Express, has spent the last 10 years taking pictures of the entire planet. To celebrate that milestone, the German Aerospace Center (DLR) has released a video compilation of images that gives the viewer the sensation of flying over canyons, craters, and mountains.
What's the Big Idea?
DLR is also responsible for the camera that's producing the images: The Mars Express High Resolution Stereo Camera "consists of nine individual image sensors, [each of which] is used to sweep the surface from a different observational angle." This results in 3D models of the surface that are extremely detailed and accurate. Largely because of this data, the ESA has extended the orbiter's mission five times, with the current end date scheduled for sometime in 2014.
We're more dependent on them than we realize.
- Scientists says our survival depends on biodiversity.
- A natural climate strategy we often forget.
- Seeing our place among the Earth's living creatures.
There's a high social cost that comes with lighting up.
While short-term results are positive, there is mounting evidence against staying in ketosis for too long.
- Recent studies showed volunteers lost equal or more weight on high-carb, calorie-restricted diets than low-carb, calorie restricted diets.
- There might be positive benefits to short-term usage of a ketogenic diet.
- One dietician warns that the ketogenic diet could put diabetics at risk for diabetic ketoacidosis.
