Very concerned, and mainly because most of the situation is avoidable. Please see the Direct Launch 3.0 proposal for details. The Ares project as originally envisioned is a good idea-
1) return to capsule-on-top-of-rocket designs for safety (no more foam strikes).
2) Use shuttle-derived hardware for speed and cost savings
Likewise, the Orion projest had some good ideas:
1)capsule design permits crew egress throughout launch (abort tower on top of capsule)
2) Capability for land and water landings.
Wel-- we have strayed from most of those and now we have a mess. NASA engineers went for a 5-stack on the Ares-I SSRB vs the 4-stack used on the shuttle. So- right off the bat, we strayed from "Shuttle-Proven" hardware. This lead to the Shaken Astronaut Syndrome issue. The engineers solved this by adding 6-tons of dead weight to the SSRB. This, coupled with issues related to the cryogenic 2nd-stage design fiddling have resulted in Ares-I not able to lift the Orion Command module as originally envisioned. The first thing to go have been safety related:
1) dry-land landing capability
2) redundant systems
Even with all of this, there are still concerns that Orion is overweight from the perspective of what Ares-I can lift. Curiously, no-one is even discussing this from the viewpoint that Ares-I is underpowered to provide the required capability dto achieve safety improvements. Michael Griffin's NASA was ***!!! PSYCHOTICALLY !!!*** committed to Ares-I (or The Stick as it has been called--- I prefer to call it The Shaft...)
Then there's Ares-V. I don't really understand why, but NASA keeps claiming that they need a bigger and bigger beast to accomplish the role of Ares-V (perhaps because Ares-I keeps looking like it will be capable of less and less?)
In what has become typical-NASA-fashion- costs are ballooning, schedules are slipping, and the sky is falling.
At the same time- small, agile, innovative companies like SpaceX and Scaled Composites are proving that genuine innovations in Rocket Science can be achieved within reasonable time and finance constraints. Elon and the rest of the SpaceX crew are poised to eat Lockheed's and Boeing's lunch- the Big Boys figured that either:
a) their substantial and well-earned reputations would carry their proposals beyond SpaceX's cost savings and / or
b) Elon's tiny little rocket couldn't possibly work.
(ha ha ha ha ha ha...........
) I figure they didn't actually soil their shorts until NASA made one of its few, really cool, truly inspired moves- they awarded the COTS contract to SpaceX. That was a *really* cool day.
The Direct Launch 3.0 proposal also falls into the "small, agile, innovative" arena. It is BY FAR the most workable design I have seen for a Shuttle replacement. The hardware they have chosen is much more "Shuttle-Derived", resulting in a (projected) MUCH shorter development period. Oh yeah- it's (projected) cost is significanty lower than Ares.
So- we have a new el Presidente, a new NASA administrator, and a new Presidential commission reviewing the status of Constellation, Orion, and Ares. The least we should be screaming to our Congressmen for is replacement of Ares-I with ANYTHING else. The Best we could achieve is total, outright replacement of the Ares Program with Direct Launch 3.0.
