- I agree wholeheartedly with that last statement, but I still believe that
- removing commercial and non-Shuttle-unique payloads from the Shuttle was a
- good idea. As I explained in my previous post, the Shuttle is a very unique
- and versatile vehicle. It has tremendous capabilities no other vehicle can
- touch, but it can only fly eight times a year. In that situation, using it
- to do things that can easily be done on other vehicles (e.g. launching spy
- or commercial satellites) is a waste of a valuable resource. The Shuttle
- should be used exclusively for missions like the Hubble revisit, the Intelsat
- satellite rescue, Tethered Satellite System, International Microgravity Lab,
- Wake Shield Facility, etc. There are no shortage of payloads to fly. NASA
- has no flight opportunities and less than a half dozen payload opportunities
- between now and the start of Space Station operations.
-
- According to the mission control status briefings, the astronauts were working
- 12 to 16 hour days. Payload volume may not have been the active constraint
- for STS-52.
