- Not true in either statement. 40,000 lbs. is about the average, if I
- reckon correctly. However I'll have to dig up copies of the Shuttle
- Press Kits for each mission to get an accurate figure. Many missions
- have been above the 40,000 lb. mark (STS-29, STS-30, STS-34, STS-41,
- STS-37, STS-43, STS-44, STS-50, all since return-to-flight.) Many of
- the military missions used the IUS, making them candidates for
- 40,000+ payloads. The next 40,000+ mission is in two weeks: STS-54.
-
- The "abort" figure you cite appears to be based on the safe return
- weight (about 35,000lbs) but this has not been a factor in limiting
- Shuttle payload capacity, as the above examples testify.
