I’m quite that just right now. It will pass. Perhaps.
There’s been some discussion in various places about both NASA and potential future launch vehicles. Everything’s just so static in a large sense. Completely hopeless. I’ll throw in the towel for now.
Almost nobody has the required long attention span or patience to make any useful progress [...]

David Harris finally wrote the article on NSF that was a long time coming. Ares V might very well move to 5.5 segment SRB:s. There goes the commonality with Ares I.
Mike Griffin, Scott Horowitz, Doug Stanley and the others might have picked an architecture with too little margins and too many limits.
In other links, the [...]

Nasaspaceflight.com’s Chris Bergin finally wrote the article on Ares I’s thrust oscillation mitigation options. There are three main ones: new pulsed brake rockets, a damper between stages and a tuned small mass damper in the SRB. All three could be applied. They also increase mass and thus reduce performance.
Ares I’s thrust oscillation coupled with the whole rocket’s already looming possible underperformance and the Orion spacecraft mass growth drives towards a possible no win situation. It’s a bit hard to know about the margins.
There is only one earlierdocument making a clear picture of the masses, performances, margins and
reserves out there:
Brian Muirhead’s presentation from 31 Jan 2008. (Thanks to Renclod on Nasaspaceflight’s forum for finding it.)
So it seems there could [...]

ESA’s Architecture for Exploration Study (AES) is overviewed in Lunar Base Quarterly 1/2008 (EDIT: to be clear, the Quarterly was released in January):
Lots of Ariane 5, Angara and Soyuz launches with space docking, a space station in Earth-Lunar L1 and many new crewed and non-crewed craft and capabilities.
They had a red team / blue team [...]

Okay, the topic of course is a pun of the current moon exploration approach chosen by NASA. It has been the subject of endless debate, and rightly so, but the various ideas for that are a subject for other days. Bush’s Vision For Space Exploration (VSE), NASA’s 90 day Exploration Systems Architecture Study (ESAS), the resulting [...]
