QUOTE Alan Stern Said: ....only HST was capable of the task, and it found them in just 8 minutes flat. Once again we're reminded of the usefulness of Hubble, and the need of one repair mission to keep it going. And no I cant place any bets on being alive in 2016, facts speaks against that so I close the book on Pluto by going with the 'collision created theory' for Charon and the two new moons. |

I remember reading somewhere online that they could build an upgraded Hubble and launch it for less than the cost of a servicing mission. Just getting the shuttle ready for launch is a huge expense. The major expense of designing the Hubble is paid for already - now they just would need to follow the existing plans to build another one. |

I still reckon that the James Webb Space Telescope is too mechanically complicated *not* to be man-tended, however!
