High-tech blimps could soon provide Hubble-like views of the sky at a small fraction of the cost of a space-based mission, a new study concludes.

Several companies, including Lockheed Martin, have been developing solar-powered blimps that pilot themselves and could remain aloft for months or even years at a time. [...] But astronomers have also dreamed of using the blimps because they would operate at altitudes of 20 kilometres or higher above 95% of the atmosphere. Telescopes at such altitudes would provide clear, space-like views of the heavens.

Weight restrictions prevent large telescopes, but even a 0.5-m wide field telescope would be very useful.

There's another thread (http://www.bautforum.com/showthread.php?t=43071) on the subject with discussion already in full swing.

Well, we could always adjust this thread's topic a bit to discuss optics in balloons in general. Maybe a laser could be mounted and used in strategic or theatre missile defense.

I once thought about taking a telescope in a balloon, but i thought, how the heck am i gonna look up?

Space based scopes will always have their uses. I can't wait for a solar foci scope.

That is... different, very cool, but different.
