THE DEMISE OF THE ARES I

The Ares I is dead, but NASA just keeps beating a "dead horse" to make it get up and pull NASA out of its 40 year slump. NASA is still stuck in an era of "bottle rockets" and "tin can" capsules. Why is the ARES I history? Let me count the ways:
1) As soon as the ARES I project was announced in 2005, there were many scientists who said the configuration was too heavy for the thrust the single, extended SRB from the SPACE SHUTTLE architecture could provide. The critics were right. Very recently, NASA reduced the crew from 6 to 4 to lighten the load.
2) The USAF did a detailed study on the ARES I and they concluded that if the ARES I failed in the first 60 seconds after launch, the crew could not escape if ground control had to destruct the configuration.
3) Vibration is the biggest reason the ARES I is a poor design. Right now, NASA is trying to mitigate the terrible vibrations that the SRB will generate by installing a series of mechanical springs between the various rocket sections.
4) The static test of the SRB just completed in Utah was successful only because NASA secured the SRB very heavily to the pad.
5) NASA is rushing to launch the ARES I in October, 2009 and this could have disasterous results.
6) Even NASA announced it was concerned with crosswinds of 22 mph or more during launch because of the slender design of the ARES I.
7) Cost overruns are already mounting on the ARES I.
8) Designing a system like the CONSTELLATION which requires building two new rockets from the ground-up was a terrible and expensive way to go.
9) NASA, in its zeal to fund the CONSTELLATION, is retiring the finest and most versatile spacecraft ever to be launched into space, the SPACE SHUTTLE.
CONCLUSION- The entire CONSTELLATION program should be scrapped immediately. The SPACE SHUTTLE program must be immediately revived. Yes, we do need a new heavy lifter, but the ARES V is not the way to do it. We can tweak the SPACE SHUTTLE launch architecture and build a heavy lifter at a fraction of the cost of the ARES V. NASA's days are numbered if it can't get its house in order and President Obama is just the man to help NASA end its wasteful ways.
