Hubble Origins Probe
TheHubble Origins Probe(HOP) was a proposal for an orbitaltelescopemade in 2005 in response to the first cancellation of the fourthHubble Space Telescope(HST) servicing mission.[1]It would have used anAtlas V rocketor similar launch vehicle to launch a much lighter,unaberratedmirror and optical telescope assembly, using the instruments that had already been built for SM4, along with a new wide-field imager. It would have cost between $700 million and $1 billion.[2]
Funding for the mission was never allocated; in February 2005,Sean O'Keefe,the NASA administrator who had cancelled SM4, resigned.Michael D. Griffin,NASAadministrator after O'Keefe, reinstated the servicing missions,[3]making HOP redundant.
