CA-1 Exploration Super System (ESS)
« on: 11/30/2005 10:57 pm »
Have you guys seen this?

http://exploration.nasa.gov/documents/reports/cer_final/Andrews.pdf

A very ambitious infrastructure to operate on moon and mars.  It involves a transfer hub in orbit at L1 for the moon, and at Phobos for Mars.

Looks very costly.

Thanks!

The CPL looks funky, still reading :)

The images alone speak volumes!

Hell, even the opening page. Love the way everything is interlinkable.

Plans and sites for manned mission to Phobos!  :o  Now this is a great read.

I get a feeling that's an out-dated document.

EDIT: The document's original creation date inside is March 7th, 2005 - well before Mike Griffin was appointed, and well before the ESAS study was commissioned, and that is the study being followed now.

It still very much focusses on the "Spirals", and makes much ado about Atlas-V Common Core Boosters and Zenit strap-ons lofting 40,000lb payloads to LEO - and everything else is based on that capacity.

First, we all know Griffin killed the spirals dead a while ago (and good riddance to the term IMHO).   Then he also announced the SDLV which will loft more like 275,000lb payloads to LEO, and will likely do all that far cheaper than the Atlas-derived system could possibly hope to do so.   Heck, at worst case (if the SDLV were cancelled) the CLV could launch more payload than that Atlas-based rocket could, and do it for 1/3rd of the cost!

I think this may have become "public" because it has little bearing on real plans any more.

There are enough warnings about export restrictions and things in that document to ensure nobody is going to give it to the public until its irrelevant.   I guarantee, nobody in their right mind "inside the loop" would risk their career and a very real prison sentence for distributing that document just for sh*ts and giggles.

What it IS useful for, is to see a 'general' outline of whats involved in building a far-reaching "Space Infrastructure", with outposts  at L1, on the moon, Phobos and beyond.   It demonstrates a very good example of the complex steps which will be required to put together a hypothetical modular base almost anywhere.   And it shows the various 'types' of equipment needed to accomplish the goal.

This document was written before the SDLV was decided upon, basing everything on the EELV's as the primary LV's.   The plan will have changed radically now, so remember that when looking at this.   The basic underlying principles are what is worth taking away from this read.

Yep, it's dated - and before this site was around (hense some people might not be aware of it). Still a good read.

Yeah, it is dated.  Still a hub at L1 was interesting to me.  It seems quite ambitious and I can see why NASA went the traditional way of going back to the moon.  But maybe someday a plan on this scale could be done by private companies.  It looks more like a permanent operation than a exploration venture.  So maybe some of the ideas could be replicated in a mining operation someday...(don't hold your breath though).

And more expensive than a much simpler HLLV.

They are just trying to use VSE to pay for their wonky Gryphon TSTO contraption.

This document seems to have gone missing!  Is it available anywhere?  The closest I could find was:
http://exploration.nasa.gov/documents/reports/cer_midterm/Andrews.pdf

which is dated December 2004.  Is that the same as the final version?  In any case the VISTA plan looks really good, both in how it is presented and in its content:
Quote
• 15 Launches from 2007 to 2015 (~2 launches per year)
• ~150T of water to LEO (19T/year) via commercial launch services
• 2 Space Tugs
• 3 Planetary Landers
• Commercial H2O to LEO service incubates other commercial LEO markets
• L1 Gateway enables highly efficient outer solar system exploration
• Lunar ISRU significantly reduces exploration launch mass requirements
• Water commerce acts as fallback if ISRU is not realized
• Ability to return significant quantities of material from the Moon (up to 15 T)
VISTA’s step wise modular approach enables synergy with other
stakeholders and encourages the placement of permanent human
outposts for sustained program extensibility.

You'll be needing the Wayback Machine!

http://web.archive.org/web/*/http://exploration.nasa.gov/documents/reports/cer_final/Andrews.pdf

That version is dated March 2005. It's substantially different from the Dec 2004 version, 118 slides versus 69.

Sweet!  Not only does it have more slides, they are prettier as well! :)
