7:56 PM | The Many Resurrections of the Hubble Space Telescope
If you are old enough to remember news stories from 1990 (or if you are a devoted student of astronomy), you'll recall that the Hubble Space Telescope was not always regarded as the technological triumph that NASA is loudly celebrating today, on its 25th anniversary. The orbiting observatory debuted as a king-size disaster: the telescope that couldn't see straight, built with a mirror that was ground perfectly...but perfectly incorrect. The story of how the error was discovered and ultima

International Space Station - Facts and Figures PageTopics: International Space Station, NASA, Space, Space ExplorationGrowing up in the Apollo era, spaceflight and space exploration were "big deals" that stopped traffic, ensued water cooler conversations and dominated - at least in nerd culture - deep thoughts regarding where we were heading. It wasn't until the Space Shuttle Program that spaceflight became humdrum; routine. We'd pause when Challenger or Columbia tragedies dominated the news […]
