NASA's Mars Orbiter Reaches Data Milestone 68

Nerval's Lobster writes "NASA's Mars Reconnaissance Orbiter has sent 200 terabits of scientific data all the way back to Earth over the past seven years. That data largely comes from six instruments aboard the craft, and doesn't include the information used to manage the equipment's health. That 200-terabit milestone also surpasses the ten years' worth of data returned via NASA's Deep Space Network from all other missions managed by NASA's Jet Propulsion Laboratory in Pasadena, California. 'The sheer volume is impressive, but of course what's most important is what we are learning about our neighboring planet,' JPL's Rich Zurek, the project scientist for the Mars Reconnaissance Orbiter, wrote in a statement. It takes roughly two hours for the craft to orbit Mars, recording voluminous amounts of data on everything from the atmosphere to the subsurface. Thanks to its instruments, we know that Mars is a dynamic environment, once home to water. 'Mars Reconnaissance Orbiter has shown that Mars is still an active planet, with changes such as new craters, avalanches and dust storms,' Zurek added. 'Mars is a partially frozen world, but not frozen in time.' While the Orbiter's two-year 'primary science phase' ended in 2008, NASA has granted the hardware three additional extensions, each of which has resulted in additional insight into the Red Planet's secrets."

    Did the math for the mathally-challenged.

    You're welcome.

  • That we haven't found Martians!

  • Just wondering if the martians count in base 10 like the cave men who count on their fingers and thumbs or if they've advanced to base 10 and powers thereof like some machines.

    With the lazors on it, and 600 meg downlink these terabytes would fill up in no time.

    The longer term plan for the LLCD is to use communications satellites to bounce transmissions between ground stations at 1.25 gigabits per second.

    In other news, server lag from lunar orbit will remain a bitch for the foreseeable future.

    I'm not sure how to read that sentance. JPL manages missions, and they also manage the DSN. But missions managed at APL, GSFC, MSFC and other places *also* use the DSN.

    And DSN's much older than 10 years ... Voyager uses it, and it was launched in 1977.

    It sounds to me like they just picked a convenient time
