I think its inclusion is significant. However, I wouldn't over-analyze the artwork.

Is there room in the trunk for both BEAM and consumables? (assuming some consumables, and maybe long term ECLSS would reside in the trunk, or is it all in the capsule)

Would any payload be possible to fit into the BEAM while it's still stowed?

Docking with the BEAM would require it not to tumble, release very carefully or have RCS on it?

Over-analyzing the artwork: the second stage appears to be left attached during the trip, used as rad-shield?

With BEAM, I point to a two launch mission with docking in LEO.

Could you put that in equivalent terms to the delta-v numbers in those L&P pages?

I'm not sure what those L&P pages you refer to are and am too lazy to go look it up, but the simplified version of delta-V requirement can be worked out from what R7 posted here

Basically, use the "V peri" number since that's where the TMI burn would take place. Subtract your vanilla LEO velocity and you got your delta-V. Vinf and Vperi are related by this equation from wikipedia:


That works out to just shy of 5 km/s departure delta-V R7 and apace already mentioned. That should be the only deterministic delta-V requirement since the Mars flyby takes you to the return trajectory. Of course some small TCM delta-V is inevitable.

Ok guys, let's try and to increase the quality of this thread.
Fixed that for ya! Just doing my bit to increase quality!

;D

Ok, so now we await the webcast.

I'm on this page: http://www.visualwebcaster.com/event.asp - so hopefully that's where to be.

A paper discussing aspects of such a mission is now out.

Thanks. Unfortunate that the closest approach would happen over the night side - although in retrospect that should have been obvious given the free return restriction. Makes this proposed mission (even) less compelling.

Interesting about the inflatable, that makes things more plausible from a crew habitability standpoint.

We already know BEAM will fit in a Dragon Trunk, so if they used Dragon, then they could in theory deploy BEAM out the back of the Trunk, then flip the Dragon around 180 degrees and dock to the BEAM (obviously BEAM would need a compatible docking port, as the ISS CBM couldn't be used). ...
Or you could use a Trogdor arm! Ask Jon Goff about it. ;)

So it is. Pretty awful quality outside of this size....but it'll do.

(Right, off on to the live thread - will keep this thread open until the top of the hour).

Chris thought that the paper was copyrighted by IEEE so he took off the post as a precaution. It has since went public here: http://www.inspirationmars.com/Inspiration%20Mars_Feasibility%20Analysis_IEEE.pdf

Seems I'm missing something from that URL as I'm getting "Error! Missing Webcast Event ID #."

Can someone post a working link?

They give 5 SOA technologies.

I'd like to see the proof that all of these technologies are qualified to 500 day usage.

Potable water by reduction of CO2?

Hamilton Sunstrand has a Sabatier reactor that does H + CO2 -> H2O + CH4 (with the CH4 vented), and it is on the space station today. In fact they did it semi-commercially so they're selling NASA water by the Liter. It's actually one of the bigger commercial success stories on the station to-date.

One observation from a quick scan of the paper: of the 24 m3 need for life support, a full 14 m3 of that is non-water food. So, it might make sense to have everything but the food in the capsule, and then the food in some sort of external container.

A sidenote, but I really wish I knew more about that reactor on ISS.

Also, from the fact sheet:

Quote
2018 launch opportunity coincides with the 11-year solar minimum, providing the lowest solar radiation exposure

And

Quote
The development of the education team and program is being led by Nancy Conrad, founder and CEO of the Conrad Foundation.

I'm sure Pete would approve. ;)
