ChopperCharles: Ya know, if they put more than a 2 megapixel camera on the rover, it would be no problem to figure out what this is. But nooooooooo, they put a dinky ass camera built on decade old technology on it. My cell phone takes higher resolution pics.

Charles.


It has more to do with bandwidth, also I believe there is a blackout period of some sort, so it can't stream 24/7. So we have a choice, a few 8 or 10 megapixel photos per day, or many more 2 megapixel photos? All those extra photos give us a LOT more data over all than a few high-res ones would, like in this case, it's pretty likely that this shiny bit would have been missed, but now that we've seen it, we can focus even closer on it.

Also keep in mind that the rover is a bit more than a camera, there's other data it's sending in addition to those photos.

ah, here's a little more info:

tldr:
bandwidth is 2Mbps / 256kbps, for 8 minutes a day, 32 kbps the rest of the time, that's why

Looks like a toenail clipping. Maybe from Elvis

theurge14: AverageAmericanGuy: You know what would have solved this mystery in a hurry?

Color photographs.

Don't get me started. It's one of my favorite rants. :(


Most people don't seem to know how a color CCD camera actually works. The CCD chip is divided into sets containing 2 green, 1 red, and 1 blue pixel (the human eye is most sensitive in green), and the tiny size of the pixels allows your eyes to blend it all together into a color image. This is exactly how your TV works. That might be fine for Earthly uses like taking shots at the beach, but for scientific imaging, it sucks. It means that 1/2 of your data falls only on green pixels,1/4 only on blue, and 1/4 only on red, making the image useless for measurements, because if a blue photon falls on a red pixel, it's lost. The different color pixels are also created by putting little tiny color filters on each pixel, which decreases the sensitivity of each pixel, because you are blocking most of the light falling on them.

Black and white CCDs therefore are more sensitive and robust, better for scientific measurements, and the whole bandwidth thing that piercedgeek mentioned. Color is supplied by filters over the whole sensor, so that no data is lost in the exposures. Yes, color gets the general public excited, but it really cuts down on the science that can be done.

So NASA went with Comcast for their space rover?

A multi billion dollar mission and they cannot afford cable ties to retain the wiring? They are using garbage bag ties? I swear I am seeing a Hefty label on one of them.

Would you rather the cable ties be wimpy wimpy wimpy?

Not twist ties. It's waxed string. That crap is ubiquitous in the areospace industry. Open just about any jet, rocket, satellite, moon lander, space shuttle, whatever and that's what is holding cables together. Hell, I've got 10 rolls of the stuff damn near in arms reach of me right now.


Yup. I used to build wire harnesses on 747's with the stuff. Very strong and reliable and most importantly resists vibration damage to the wire. I had a cool little curved ring knife that made tieing the string and cutting it very quick.

Your cell phone also wasn't built to withstand extreme temperatures, intense radiation, and a 90 million mile trip through interplanetary motherfarking space, now was it?

Unless, I dunno, maybe you've got one hell of a cell phone.
