Satellite Imagery Used to Trace Lewis & Clark Route

Woogiemonger writes "To commemorate the 200 year anniversary of the Lewis & Clark expedition, NASA and other researchers are using satellite and aircraft remote-sensing technology to accurately reconstruct the path of the Lewis & Clark expedition, down to the precise location of each encampment. Considering many parts of the landscape along the path may have changed dramatically, this is no easy task. The final result will be a 3D interactive map publicly available on the WWW."

Lincoln in Mandan. My grandfather helped design the interpretive center, some engineering work and although the latter wasn't constructed until 70 years later it gives you a glimpse into the frontier past of the upper midwest. General Custers rebuilt house, a wooden fort circa 1870 and Mandan Indian Earth Lodges you can go into.

      The Missouri has been damed up in many spots and only 3 or so spots remain where one can see the river as they did, from Garrision Dam south to Bismarck (canoed it for 5 days last summer for the second time, very very beutiful) and two sections in Montana before and after FT. Peck Dam. South of Bismarck is Lake Oahe and further south then that going into SD and Nebraska it is kinda polluted.

      Really? And you consider the fundamental advancement of space technology (in any shape of form) to be less important than entertainment?

      Except that this "fundamental advancement of space technology", in the case of the ISS, is being done primarily for its entertainment value!

      The ISS is a crowd pleaser, nothing more. Real projects for real science are being hacked and cut so we can have a habitable garbage can in low earth orbit. For example, soon Pluto's atmosphere is going to freeze and blanket its surface, rendering Pluto unvisitable in any practical sense, for a hundred and fifty years. We had a probe ready to enter the Pluto-Charon system before this would happen but it got hacked because of ISS cost overruns. In fact, NASA is hardly doing anything interesting anymore because of that stupid ISS. They're the ISS agency now. The scientific community hates the ISS. The general public loves it, because they're scientifically illiterate and believe it will lead to bigger and more interesting manned spaceflight, but the ISS has little scientific or practical value other than allowing us to observe the horrible long term effects of weightlessness and ionizing radiation on people in space. (In fact, this was one of the very few rationalizations actually offered by its proponents.)

      NASA is wasting it's money daily, this is just another example of that waste.

      NASA will save a lot of money for way more worthwhile projects if it mothballs this orbiting turkey. Crashing the damn thing into the ocean would be an even better idea if there were enough political will to do it. It breaks people's hearts, and they don't want to believe it, but manned space flight in general is a dead end and an immense waste of money.
