What Will NASA Do With Its Gifted Spy 'Scopes?

astroengine writes "NASA has begun surveying scientists on what they would like to do with two Hubble-class space telescopes donated to the civilian space agency by its secretive sibling, the National Reconnaissance Office — which operates the nation's spy satellites. But the gifts have some formidable strings attached, including costs to develop instruments and launch the observatories. The telescopes, though declassified, also are subject to export regulations. 'We need to retain possession and control,' NASA's astrophysics division director Paul Hertz told Discovery News. 'That doesn't preclude us from partnering (with other countries). It just sets boundaries on the nature of the partnership.' NASA also isn't allowed to use the telescopes for any Earth-observing missions. Topping the list of possible missions for the donor hardware is a remake of NASA's planned Wide-Field Infrared Survey Telescope, known as WFIRST. The mission, estimated to cost between $1.5 billion and $2 billion, is intended to answer questions about dark energy, a relatively recently discovered phenomenon that is believed to be speeding up the universe's rate of expansion."

      That's why Hubble was useful in the first place. As a telescope, it's not that impressive - far bigger and fancier ones exist. What sets it apart is that it is above all that atmospheric interference.

      Well, not quite... the adaptive optics on modern ground-based telescopes can deal with much of the problems associated with atmospherics. The real win with Hubble is that a) it can look in wavelengths that are heavily attenuated by the atmosphere (Think UV and Infrared) and b) it can stare at a target, continuously, for very long periods of time. Earth-based telescopes are (obviously) limited to observing at night, while Hubble can continuously observe a large portion of the sky on a continual basis (24 hours, 36, whatever). This is especially important when you're trying to observe extremely dim targets who's brightness can be measured in photons per minute.

Unless the government has been amazing at hiding insanely advanced science and technology from the rest of us(and keep in mind, they have a hell of a time hiding a *sex scandal*), it is actually impossible to read anything through a roof from space. You can zoom in all you like(not actually true, but we'll give them the benefit of the doubt here.) All you'll get is a better image of the roof.

      Sci-fi writers, myself included, can generally get away with using infrared from space to track warm bodies in a cool environment(or cool bodies in a warm environment), but even that fails through, say, glass, which isn't transparent to IR. Also, a dime, being metal, will probably be at the same temperature as its environment.

      Maybe they could use x-rays, if you've got a powerful x-ray source under the dime. Or neutrinos, if you're using dimes either thick enough to reach the satellite in orbit or that are made out of neutronium. Of course, if you've got a 400 km thick dime, reading the date on it would probably be pretty easy, if you had a really fast camera, a good eye, and didn't run into the massive dime-tower at 25,000 mph.

      It's a fair bet the government has access to technology far better than we do, but if they had access to that level of tech, they wouldn't have to resort to drone strikes on terrorists.

      They'd simply suck them through a wormhole into the sun.
