Cancer Posted October 24, 2018 Report Share Posted October 24, 2018 There's only one set of essential mechanical parts in most spacecraft, and those are the gyros. Not surprisingly, those are very often the thing that causes mission-ending failure. Quote Link to comment Share on other sites More sharing options...

Old Man Posted October 25, 2018 Report Share Posted October 25, 2018 Which one, the bad mirror problem? I remember reading a long magazine article that trumpeted the feat of engineering that was the HST main mirror... Quote Link to comment Share on other sites More sharing options...

novi Posted October 29, 2018 Report Share Posted October 29, 2018 Yup, an awful lot of stupidity and pride went into getting the Hubble mirror wrong. OTOH, they got everything else right about the mirror, which is why Hubble is still going strong these days - being very precisely the wrong shape, it's (relatively) easy to design optics to compensate for the incorrect focus.

Logan D. Hurricanes Posted December 18, 2018 Author Report Share Posted December 18, 2018 NASA Research Reveals Saturn is Losing Its Rings at “Worst-Case-Scenario” Rate ? https://www.nasa.gov/press-release/goddard/2018/ring-rain Quote Link to comment Share on other sites More sharing options...

Cancer Posted December 18, 2018 Report Share Posted December 18, 2018 It has long been realized that ring systems have to be episodic things. The lifetime of ring particles is much less than the age of the Solar System; therefore, the rings must be being replenished. Now, Enceladus is generating ice particles that are going into the ring systems, so that's clearly one source. It can't be the source for the big showy rings we're used to seeing. It raises the interesting question of where the current rings come from. The current mass of the ring system is about the mass of Saturn's moon Mimas ... seen here. Mimas is also the one with the rather Death Star weapon-looking big crater. Which leads to the interesting idea of two Death Stars going into station-to-station combat... Saturn orbit as site of "WWE of the Worlds" bouts? Yeah, that's an idea we had some time ago.... Logan D. Hurricanes 1 Quote Link to comment Share on other sites More sharing options...

Starlord Posted December 19, 2018 Report Share Posted December 19, 2018 So every time it gets updated, the Hubble shuts down until the update is updated? Quote Link to comment Share on other sites More sharing options...

Cancer Posted December 19, 2018 Report Share Posted December 19, 2018 Well, it isn't getting any more updates, so that isn't an issue (if indeed it ever was). Quote Link to comment Share on other sites More sharing options...
