Post a BAD Altair design   Posted on: Fri Mar 07, 2008 12:54 am
.

apart its, old-looking, BAD design, the latest Altair concept shows a TOO little (phone-booth-sized) ascent-stage's crew cabin:

At leat the astonauts will be able to phone home when they get to the moon, though putting a phone box on the lunar surface is totally unnecessary with everyone having a mobile. Then again mobiles are quite small and perhaps they couldn't type in the number using space gloves. :)

Dammit, don't you see what it is? It's a bloody breakthru! It's TARDIS! NASA have invented TARDIS!

You saw it here first, especially gaetanomarano!

true, but only one astronaut a time, since, the Altair phone-booth, is not enough large for four... :)

maybe, they have hired David Copperfield... :)

seriuously, the problem is not so little, also assuming it's internal space will be enough to host four astronauts (like fishes in a barrel...) this very expensive vehicle will have NO life support redundancy NOR margins for extended missions' duration, that's VERY BAD for a "plan" that's going to cost over $230 billion in the next 20 years!!!

also, a so small (just to fit four astronauts) Altair, clearly shows what I've ALWAYS said in latest two years on my website and blog and on space forums: the current Ares-5 is underpowered and its "130 mT payload" target is too little (that's why I've suggested to develop a 200+ mT cargo launcher)

Nah, they have mastered trancendental engineering. Like the discraft guys.

But the original LM had no redundancy, no margins and very little space. It wasn't even designed to cater to the whole crew. This will be a step up.

Being able to live in a barrel is part of being an astronaut.

If they had bigger launcher the responsible thing to do would be more people in a slightly larger barrel, not luxury apartments for everybody.

Didn't anyone notice that the those phone booths are not the correct scale when compared to an astronaut? :P

I was just happy to realise where all our red phone boxes went! Prob find some red post boxes and prince Harry there too!

I dont think all the phone boxes went to the moon, that must be one that Superman used to change in from Clark Kent when he battled the baddies there. :)

I think that using Willy Wonka's Glass elevator would have been more appropriate, at least its got rockets on it. :)

an excess of risks was very common (and inevitable) in the early years of spaceflights (that's why the Shuttle was designed without escape systems) but, today (especially after the Challenger and Columbia accidents) this kind of (evitable) risks are unacceptable since, now, the technology allows to reduce it to a minimum

unfortunately, the Altair crew cabin seems very much smaller than a fishes' barrel... :)

send twenty astronauts for a week is irresponsible and irrational, while, send four astronauts for a month is rational and economical

The phone-booth near the Altair ascent-stage looks too big, since, the astronaut near it is not in his full size, but a little back and down in the image (probably on a platform or a stairs) so, his image doesn't starts from the "lunar boot", but just near his knees, up.

I've just updated my Altair article with new data and images, so, it now is a true and detailed analysis of the ESAS lunar lander:

http://www.ghostnasa.com/posts/025badaltair.html

one of the most interesting things added is an evaluation (by comparison with the Orion) of the real dimensions of the Altair's crew cabin:

2.5 by 3 meters is too small exactly why?

It's bigger than a scottish phone booth. They crammed 16 people into one, so why wouldn't they be able to squeeze a few astronauts into something significantly bigger?

1. these are the EXTERNAL dimensions, the internal is much smaller (as explained in my article)

2. the phone-booth is for one-two persons, while, the Altair, must(should) be for a crew of four

3. the four astronauts won't exactly make a phone call in it, but live in this small crew cabin for (at least) 100 hours (excluding the EVAs)
