End of the Road For NASA's Mars Rover?
An anonymous reader writes "NASA celebrated Mars rover Spirit's bountiful, six-year stint on the red planet on Sunday – way longer than its forecast three-month mission. But it all may soon come to an end, stuck as it is in Martian sand."
I wish the poster had done a better job summarizing the situation. Spirit is stuck in the sand and can't rock itself free; because it's not moving, sand and dust is collecting on the solar panels; winter is coming on Mars, making the solar energy that much weaker anyway.
But even as cute little rover sits there spinning, its wheels are doing Science, they dug down to a layer with sulfur. Sulfur indicates hydrothermal vents, and hydro is the greek word for water. Woot!
A miracle could happen; a sandstorm could clean off the solar panels, allowing enough energy for a mighty push that could free the machine.
I'd just like to take this opportunity to tip my hat to the folks that designed this rover. It was slated for a 180 day mission, and they just finished up day 2,190. That's some pretty high quality engineering that must have gone into this project, especially when you take into account it's on *another planet*, so no tech to fiddle with something that's just a bit off here or there.
No parts, no cleaning, no help at all. To top that off, it's doing all of this on Mars, which isn't really an electronics friendly environment. It crash landed on another planet from a rocket ship and worked 10x longer than it was supposed to.
Well done.
IIRC they put it in "low power mode" last Martian winter and were pleasantly surprised when it survived, booted up, and restarted communications with Earth again when there was enough sunlight available. The trouble is, this year it's stuck at a less-than-ideal angle for collecting sunlight so there may be less of a chance of a springtime startup unless they can adjust the position, which of course takes, well, power. It's a risk either way. Plus, I think it's just locked up a second wheel, leaving it with 4 of 6.
So we'll see. If it can't move again but gets power, its utility as a science platform is going to be severely impacted. Still, it will be able to collect data and pictures of the changing landscape in its immediate vicinity, and it seems to have gotten stuck in an interesting spot, so there will still be useful data coming out of it.
And since the warranty ran out 5+ years ago, I think even a partly functional stationary science platform is pretty darned impressive.
Even after six years, the simple fact that Mankind has working scientific instruments on Mars gives me a geekgasm all over again.

"the lost century: the millennial archive hole"
abstract: paper archives from the 1900s are still useable today, the only barrier being language conventions of that time period. additionally, digital records from the 2100s are usable today, due to mandated standardization of file formats and the prevalence of cheap, eternal nanoholographic storage. however, the 2000s consisted mainly of magnetic and optical storage on flimsy media. additionally, file formats were often proprietary, quirky, and ever changing due to the rapidly evolving nature of digital technology from that early era. if the actual media itself wasn't degraded, the file format itself was usually forgotten in a generation or two. finally, many early groundbreaking sites of the primitive internet are lost to posterity simply because they were designed to be ephemeral and ever changing, and no one thought to take archival snapshots of their content. it didn't seem important at the time. and so, the early decades of the digital age, when many fundamental crucial decisions were made that have defined our culture today, are forever lost to us
