Either that or we can see the 90% eclipse up here and make plans for 2024. I completely forgot about it being next year until a few weeks ago. 2017 seemed like ages away when I first moved out here.

Yeah, I think if we are going to go, it'll be just a drive down for the event and drive back.

There's always 2024, too, of course. I saw 85% totality during the 1999 eclipse, and while it's nothing like seeing the corona, it was still pretty cool to see the sun as a crescent.

This video is interesting for several reasons, IMO most notably that NASA is in the habit of discarding data that it cost $billions to collect.
When YouTube can store 300 hours of video data every minute, year after year, is it really too much to ask that data paid for at massive expense by the US taxpayer should be securely archived and available for future research?

Re: Spaceships and astronomy
Because the warming effect of internal stuff, like the RTG causes the surface to emit photons of infra-red light, these exert a force.

The final descent snaps from Rosetta were a bit like Ansel in Yosemite, don't ya think?!

Anyway, kind of cool that some 21st century Earth junk is on a comet heading out into space.

Re: Spaceships and astronomy
This thread needs a bump. Speaking of bumps, here's the initial conclusion from the ESA on their hard landing on Mars...

It does seem a bit amateur that an expensive mission failed because their landing computer was poorly programmed.

Re: Spaceships and astronomy
I am not sure that it is any more amateurish than having scientists using thrust measured in newtons confused by engineers using thrust measured in pounds force, which doomed the Mars Climate Orbiter in 1999. Ironically the mission was very similar to the ESA mission.
