Those dates usually change, so don't worry too much. Plug for our Pan-STARRS system: It will allow much wider surveys from the ground, including 5000 Type Ia supernovae.

Steinn as usual has the straight dope on this; quoting from his comment on CV: "The current word is that the servicing mission schedule is full with other priority tasks and the training schedule is also full, so they will most likely not attempt a repair of the ACS." This is also described in Dennis Overbye's NYT article today. When it comes to servicing missions, NASA loves to set things up in such a way that the astronauts can do more than they promised --- it makes for a heroic story. (I've heard this straight from the mouth of a higher up at STScI.) But in this case, the repair sounds so extensive that I'm inclined to believe that they really won't be able to do it. and so it is expected that this instrument will be replaced as part of the already scheduled work for that mission

The <a href="http://www.nytimes.com/2007/01/30/science/30hubble.html?_r=1&oref=slogin" rel="nofollow">NYT article</a> presents the consensus out of GSFC as saying the camera will not be repaired: <blockquote> [Preston] Burch and his colleagues said it was unlikely that they would be able to repair the camera during the next Hubble servicing mission, which is scheduled for September 2008. On that mission, astronauts will replace the wide-field camera with a powerful new version, wfpc3, which will extend the telescope’s vision to ultraviolet and infrared wavelengths and restore the lost capabilities. They will also install a new ultraviolet spectrograph and make many other pressing repairs. </blockquote> <a>Julianne seems to agree</a>. That’s interesting.
