A downward-pointing camera on the front-left side of NASA’s Curiosity rover will give adventure fans worldwide an unprecedented sense of riding a spacecraft to a landing on Mars.
The Mars Descent Imager, or MARDI, will start recording high-resolution video about two minutes before landing in August 2012. Initial frames will glimpse the heat shield falling away from beneath the rover, revealing a swath of Martian terrain below illuminated in afternoon sunlight. The first scenes will cover ground several kilometers (a few miles) across. Successive images will close in and cover a smaller area each second.
The full-color video will likely spin, then shake, as the Mars Science Laboratory mission’s parachute, then its rocket-powered backpack, slow the rover’s descent. The left-front wheel will pop into view when Curiosity extends its mobility and landing gear.
