Is this really NASAs final service call to Hubble or could a future spacecraft like Orion attempt some type of flight?
From what the mission scientists said, this really is the last call. Orion won’t be in place until no earlier than 2015, and Hubble is meant to be serviced every three years (this is the longest it has gone – seven years – without servicing). They also haven’t commissioned any new parts and those would take awhile to build if they did want to send anything new up there.
