Too bad about the Martian Rover

Ranch work today instead of web work. We're getting the property and equipment ready for spring.

It's too bad about the Martian Rover. It's having problems and NASA/JPL aren't sure what's wrong. See their press release below. Today it did communicate with Earth using a satellite orbiting Mars. Story from JPL below. This nice graphic from the San Francisco Chronicle shows how that communication link works. Click here to view. (147K).

"NASA's Spirit rover did not go to sleep today even after ground controllers sent commands twice for it to do so.:

"Shortly before noon, controllers were surprised to receive a relay of data from Spirit via the Mars Odyssey orbiter. Spirit sent 73 megabits at a rate of 128 kilobits per second. The transmission included power subsystem engineering data, no science data, and several frames of 'fill data.' Fill data are sets of intentionally random numbers that do not provide information."

"Spirit had not communicated successfully through Odyssey since the rover's communications difficulties began on Wednesday."
