I think a big reason Hubble managed to do that was that it captures in the visible spectrum due to being a repurposed spy satellite. That spectrum just isn't that interesting these days afaict, especially since ground based observatories have gotten a lot better at seeing through the earth's atmosphere. The false color images of most of today's missions are just a lot harder for the public to understand. It was also launched in a time where NASA desperately needed good publicity.
- izacus 5y ago"... due to being a repurposed spy satellite." What? Where did this come from?
- segfaultbuserr 5y agoKH-11 ("Keyhole-class") spy satellites. It's generally believed that Hubble's optical technology came directly from that. > KH-11s are believed to resemble the Hubble Space Telescope in size and shape, as the satellites were shipped in similar containers. Their length is believed to be 19.5 meters, with a diameter of up to 3 meters (120 in). A NASA history of the Hubble, in discussing the reasons for switching from a 3-meter main mirror to a 2.4-meter (94 in) design, states: "In addition, changing to a 2.4-meter mirror would lessen fabrication costs by using manufacturing technologies developed for military spy satellites". https://en.wikipedia.org/wiki/KH-11_KENNEN https://en.wikipedia.org/wiki/KH-11_KENNEN
