Young electronics people who see this should look up the power and versatility when working with Field Programmable Gate Arrays or FPGA. a joe in Texas

According to Ashwin Vasavada, JPL's Mars Science Laboratory deputy project scientist, the slight haze seen in panorama shots from Curiosity is atmospheric dust usually present during the Martian summer.

You're right, NASA has done this with other rovers and emphasized that this software update was planned a long time ago. Curiosity will be the most autonomous rover ever landed on Mars, and that requires plenty of reprogramming. BTW, NASA said it expects the first drive on Gale Crater to occur as early as next week.

Uploading of software from earth is not a new thing for NASA. As per my knowledge they did it back in seventies when the on board computers had very limited memory ( just a few kilobytes then)

It won't crash as Curiosity has redundant computers. Even if the update fails, it will have its recovery mechanism. But really I can't imagining upgrading a firmware from Earth to Mars! Truely amazing! The picture is nice. What time of the day on Mars this was taken? Looks dawn to me :)

"I wonder why the Martian sky always look so dusty." Frequent and sometimes heavy dust storms.

I hope it does not crash the rover after the update. The MARS atmosphere is only 1/100th as thick as the Earth's, I wonder why the Martian sky always look so dusty.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
