Launch is the only way to test. The launches were beta testing since customers flew on it. Alpha testing would be with no payload

Lies, damned lies, and statistics. Of course the statistic isn't a lie. The problem with that statistic is that had SpaceX decided to name the recently launched vehicle something else, then that statistic would be invalid.
Back to Taurus II discussion, once the LV is up and running has Orbital thought of using a pad at Kodiak? It would make available a polar launch site which I believe Wallops lacks, plus it avoids the big boy situation at Vandenburg, plus Orbital already launches Minotaur from thereAlso, what other payloads besides Cygnus is Orbital looking to launch on Taurus 2?
Though does anyone have any numbers on the TO of it's upper stage since that could completely preclude manned use until a new upper stage is built?

Quote from: A_M_Swallow on 08/24/2008 09:40 pmLimits on computer power probably restricts simulation testing to only components or a (simplified) whole launch vehicle but not both. Wrong. It has nothing to do with computing power. 1. There is no component level simulations. It would accomplish nothing. Components are tested but it is not in an LV simulation.

2. The avionics are run in a lab doing full up simulation. 3. Mother nature and real world effects can't be modeled.

...we need the High Energy Second Stage (HESS) for performance
1. Just about anything that requires a delta II class LV, probes, small and medium sized satellites, the usual stuff.2. Though does anyone have any numbers on the TO of it's upper stage since that could completely preclude manned use until a new upper stage is built?
A sufficiently detailed simulation would have caught the burp.I would rewrite 3 as there is insufficient computing power to model mother nature and the appropriate subset of the real world. This is ordinary chemistry and Newtonian physics.
...we had to address it with the TU-903...
You say this in a way that implies that there is a sketch design at least for this Taurus 2 HESS...any truth to that, or just wishful thinking?
