Does this mean that some people with the proper equiptment could intercept
digital image downloads from the HST, (in the future of course)?

HST uses the Tracking Data Relay Satellite System (TDRSS), which is encrypted (with something presumably stronger than DES). It would be the proverbial good thing if someone at STSCI would make some of the images available via anonymous ftp.... -=Paul Flaherty, N9FZX/VK2WYX | "Anything below 1,000,000,000 Hz ->paulf@shasta.Stanford.EDU | is just nervous DC."

Paul, the HST PI's have exclusive access to HST data for a year after it's acquisition I believe. This is inline with NASA policy for spacecraft data. This is the reason that no images of the voyager Neptune encounter (except those digitized from NASA Select video by Stanford) have been released to the public (except for press photos). If the PI's choose to release data early, I guess this could be made available. This is designed to protect scientists who may have waited years for their experiment to fly, and not allow some 3rd party to quickly analyze the data and publish before the PI can. I think this is reasonable, but it certainly can be frustrating. Perhaps it would be possible to get some low resolution bitmaps of press photos released to the public. Thanks, Milo PS Usual disclaimers about this not representing NASA or Government policies or positions apple of course.

It would certainly not be a good thing for their network connection and whatever machine hosted the images, as it would rapidly be swamped under hundreds to thousands of connections. Using the Internet to copy large images merely to satisfy people's curiosity and/or give them more background bitmaps is not wise. -- Jon Leech (leech@cs.unc.edu) __@/ ``There ain't hardly nothin' cuter nor a sleepin' baby tad lessen it's a pork chop'' - Churchy La Femme
