Re: HST question
Hi Raoul,
Hmm... I was reading through all the 3B mission info and they all seem to say that COSTAR will be pulled and replaced with the ACS and a new FOC that will have the corrective optics built-in. So basically COSTAR will be completely removed after mission 3B.
It is not only the FOC that needed COSTAR to work by the way-- WFPC1 needed COSTAR too. On the second servicing mission, WFPC1 was pulled and the replacement WFPC2 was installed. WFPC2 has corrective optics built-in and so does not need COSTAR.
