Orbiter Reveals Rock Fracture Plumbing On Mars

Riding with Robots writes "Mars researchers report that a robotic spacecraft orbiting the Red Planet has revealed hundreds of small fractures exposed on the Martian surface that once directed flows of water through underground Martian sandstone. 'This study provides a picture of not just surface water erosion, but true groundwater effects widely distributed over the planet,' said one of the mission scientists for the Mars Reconnaissance Orbiter, which has been regularly returning terabytes of high-resolution images and other kinds of data from Mars."

Longer than that. It only has LOS with earth for 16 hours a day and uses 10 to 11 of those hours for data transmittal.

I was somewhat disappointed that the NASA page discusses the data in terms of how many CDs they would fill; however, at least they didn't try to tell me how many football fields would be required to lay the CDs edge-to-edge.

You could have gone to the homepage http://mars.jpl.nasa.gov/mro/
There it states 67.5 Terrabits received. (Terrabits, not terrabytes)

And on http://mars.jpl.nasa.gov/mro/mission/sc_telecomm.html it gives a different figure, but that is static data, while on the first page it looks as if it is dynamic information.

The spacecraft has already provided more than 50 Terabits -- that's 50 million million bits. To put it another way, that's more than all the data transmitted by all previous JPL spacecraft put together!
