Today (yesterday in the US) was a day for good news from NASA. First, it confirmed that there will be a shuttle mission to the Hubble Space Telescope, with the intention of extending its mission to 2013. Not only will the mission (scheduled for some time in 2008) fix current problems with the telescope, it will also install new instruments: the Cosmic Origins Spectrograph (COS) and the Wide Field Camera 3 (WFC3).
Then, NASA also announced that the Deep Impact probe will have its mission extended to meet comet Boethin in December 2008. This is the probe that released an impactor towards comet Tempel 1 on 4 July last year; it will not make physical contact with Boethin, but will use its instruments to study its composition.
