- that's not the point. The point is not what we WILL be doing but
- what we COULD be doing. The first step to change is realizing that
- alternatives exist.
-
- We could fly Soyuz on an Atlas or Titan. We could build a small
- station with room and power equal to Shuttle. We could dock the two
- and get far more work done for far less money. We could then use the
- savings to fly more experiments and furthur open the space frontier.
- That is what we can do with conservative engineering.
-
- Alternatively, we can follow the Coffman school of engineering which
- states that nothing which doesn't exist today can be built. Under this
- plan, we support Shuttle (since no alternatives are possible) and
- spend our lives siting on this rock.

-
- Shuttle isn't getting us anywhere. Wrose, is sucks up all the money we
- get preventing progress. DC can work but it may not work. We need alternatives.

-
- We don't use Russian rockets; we use Atlas or Titan. Both routinely rebuild
- their launchers to conform to payload interface requirements and NASA's
- evaluation of Soyuz as ACRV indicate that using Soyuz with US aerospace
- standards isn't a problem.
-
- As for stability, that isn't seen as a problem since NASA will be using
- Soyuz for ACRV.

-
- Send them to an industrial space facility. We have build space stations
- before and replacing Shuttle's limited ability in orbit shouldn't be
- hard. We already have Spacehab and Spacelab and it shouldn't be hard
- to add power and facilities to them. Keeping the lab in orbit will allow
- greater utilization and cut costs even more.
