I've really enjoyed watching the progress of SpaceX -- Falcon 1, Falcon 9, Dragon, etc. They have done a pretty good job in keeping the general public informed via twitter, live video, etc.rickfm wrote:The end of the shuttle era was such a sad moment, to me. To see this amazingly ambitious technology succeed is such a shot in the arm for American space exploration.
Look out below! What descent to the surface of Mars looked like from my POV #MSL #MARDI [video] http://bit.ly/OIqmBW

The press conference said that Curiosity only got 90 watts from its RTG (nuclear) power source, so it had to rely on solar cells and a battery to store up enough power to move, which takes 130 watts. One reason for the "wimpy" computer is to keep power consumption low.Curiosity needs OS upgrade before getting down to science
New software release on the way to wimpy martian computer
Curiosity Mars mission The Curiosity Rover will upgrade its operating system before getting down to serious science, NASA said today.
The Rover's onboard computer has wimpy specs, boasting just:
* A BAE RAD 750 single-board computer with a 200Mhz Power PC CPU;
* Two gigabytes of flash memory;
* 256 megabytes of DRAM
* 256 kilobytes of electrically erasable programmable read-only memory
At a press conference today, NASA suggested the latter is about to get a workout, with panellists saying the Rover's flight computer needs an upgrade before it can start to perform sophisticated experiments.
