Even Al- Jazeera has an article on Beagle 2!
(too bad for the slight error: rocket instead of sat, but interesting article nontheless... Some trivia I didn't read elsewhere...)

While we're at it, NASA could very well be issuing panicky statements if they were in the same boat... Lately they use to warn everyone how difficult all this stuff is, ever since Columbia... They're still a bit shell-shocked...

(Damn... the mere thought of Columbia breaking up makes me sad...)

#3454 Re: Not So Free Chat » Holiday Wish List - ...Cosmic Style » 2003-12-24 18:05:32

YES! YES! YES! Shaun...

That's one of my daydreams... All world-country-fiefdom-big corporation-...leaders should take a trip Out There, to see what they're 'ruling'.... give them a new perspective of things. (litteraly)

#3455 Re: Unmanned probes » See the 'Race' unfolding - on this constantly updated map! » 2003-12-24 17:59:27

i found the first on Everything Space Messageboards in spaceflight/The Mars race... then messed a bit with the link to see where it came from, and found the second one. (there are two more, but not sso interesting...)

Darn, i won't be able to sleep tonight... Beagle beagle beagle....

#3456 Re: Interplanetary transportation » Low-cost-reusable vehicle design-FICTION - possible to actually do this today? » 2003-12-24 16:22:36

Just to notify there are further updates on the on-going story, all equally detailed...
One chapter about different ways to use a heat shield, for instance... Amazing stuff.

Ok, this is fiction, but the science behind it is oh-so interesting...

#3457 Re: Unmanned probes » You RAT » 2003-12-24 05:33:20

Aetus, you sure? The driller on Beagle 2 was invented by a dentist, would be a serious 'dentist renaissance' in space exploration if this one was also coming out of the dentist's lab big_smile

#3458 Re: Human missions » Post Kitty Hawk Momentum Shifts to Mars - Marssociety headline » 2003-12-24 02:24:48

The thing with the OSP is (was?) that it got pushed, while no one knew if it would be really useful. Te only thing that was sure about it, was that it would cost time and money... for a glorified life-boat, not a full-fledged piece of hardware. So it's good it got virtually scrapped, means people are starting ro rhink about 'the bigger picture'
In the short run, is seems negative: "we build nothing"
but overall, WHEN something 'll be built, it won't be a simple over expensive life-boat.

There's a perfectly capable Soyuz and Progress, The European Automated cargo delivery stuff will be in use shortly, so America should focus on something else, not copy this.

But what?

#3459 Re: Human missions » Post Kitty Hawk Momentum Shifts to Mars - Marssociety headline » 2003-12-23 14:12:49

"We won." might be a bit overoptimistic, but... IF the landers do ok (15% chance, duh) then hing look good.

in other news (Aviation weekly): OSP has been indefinitely postponed! GOOD! Finally people are starting to realise it would be a dead end road.

#3460 Re: Meta New Mars » Mars Society link? - Or am i just dumb... » 2003-12-23 07:53:01

All of a sudden i realised there's no direct link to the Mars Society on the 'intro' screen of this board...

Or maybe i'm simply overlooking it?

#3461 Re: Planetary transportation » Airplanes on Mars » 2003-12-22 08:49:47

The problem with planes on Mars... is that there are no runways...

*every* single picture you see, be it Viking, Sojourner, and let's hope: Beagle 2 and the two Rovers... shows thre's millions of small rocks, strewn around the surface. Don't see how a plane could land there...

What we could do is launch a 'bulldozer-rover' that makes a landing and take-off strip... But i don't see that happen in the near future. Verical take-off and landing is a solution: balloons, helicopters, the 'insectbots' ...

Planes would just be doing suicide-missions, now.

#3462 Re: Life on Mars » Are there people against contamination of Mars? » 2003-12-22 07:40:17

I know some bryophites that would love to live there.

Can you give some more info on that? I've always been interested in this kind of stuff, but i'm not a botanist/biologist and a lot more ... not (if you know what i mean)

Do you think there are organisms on Earth, already capable to survive on Mars?

#3463 Re: Planetary transportation » Airplanes on Mars » 2003-12-22 07:24:58

The X-plane simulator is cool, they keep upgrading it, hours of fun to be had (you can build your own stuff also)

Frankly, I don't like the whole 'plane-on-Mars' idea, for the same reason as Mad Grad Student: a mission that lasts one hour? Crazy...
It SOUNDS cool but it's idiocy, sorry for the bright minds working on it, but i guess there's a good reason that at least one of them started looking into alternatives, as Shaun's submitted link shows... in another thread...

Hi, Dwain!

That's one impressive introduction you make! smile  Looks like a great project you did, too bad i can't run it (really ancient computer)

I hope you stick around for a while on this board and have some fruitful discussions (can you tell i'm impressed by your achievement?)

So, a BIG welcome!

#3465 Re: Science, Technology, and Astronomy » Space Elevator » 2003-12-21 11:53:37

i was going to reply that i thought they already announced something like that, years ago...

Shaun, that's a relatively old article you dug up...  Wonder if their claims still stands, today

#3466 Re: Unmanned probes » Another Reason to Send People - They $ave Big Cash » 2003-12-21 11:36:34

Shaun, that's a great little page! Didn't think for a sec it would be possible...

I'd say forget the plane, go for the heli, waaay cooler thing to develop !

#3467 Re: Life on Mars » Mars Sample Return - Threat of back-contamination » 2003-12-21 04:11:28

Everytime NASA attempts a launch somewhere, the comments/jokes about the English/metric thing resurface... I guess they're really tired hearing it.

To their defence: it was bound to happen sometime... Since engineering largely uses the English system, and the scientific communty the metric... that's simply asking for trouble.
Then again, the "faster,cheaper,better" idea was inherently flawed, If you want to build something, EVERYBODY knows you can pick two of those three qualities, but not all three. I guess this time they wanted to go too fast. It should've been : slower, cheaper, better.... (slower: more testing)

#3468 Re: Human missions » Reasons against Mars Direct » 2003-12-21 04:02:44

... worries about how quickly they might de-adapt.  After all, a manoeuvre such as aerobraking into martian orbit may require an A-1-normal vestibular reflex condition and hand-eye coordination.

De- adapting could be a problem... But not for aerobreaking, etc. As much as we like the mental picture of a 'hot' space-pilot, doing incredible manoevring, it all should be totally automatic. Of course if things go totally SNAFU, there would be some manuall-override capabilities, but i don't think humans are capable to do all that high-precision stuff. The real steerin must be done with computers, some button-pushing by astronauts should be good to give them at least the morale-boosting impression they make a difference, but that'd be merely symbolical.

De-adapting on the surface, OTOH... imagine that all of a sudden you have to de-adapt AND put on your heavy suit, climb off a rickety ladder, and negociate a rock strewn plain... That could be one small stumble for a man, a giant circus for mankind... :laugh:

Very simple: lock all but one of the wheels, let the remaining one spin freely, et voila!

#3470 Re: Youth Group / Educational Outreach » Mars Funzone for Kids! » 2003-12-21 02:36:39

Can't help but feeling a bit... betrayed
2004 (almost) and what do the big space guys give us: on-line games... sad




(Though i have to admit i like the JPL stuff. Why don't we scrap NASA and let them be the bosses?)

#3471 Re: Unmanned probes » Another Reason to Send People - They $ave Big Cash » 2003-12-21 02:16:04

plus the fact that a human geologist/scientist works *much* faster than a robot: looking around, intuitively knowing where to go, what to pick up... Robots have to be commanded, and with the time-lag even simple things like going from A to B becomes hopelesly complicated, so i think humans are even more efficient...

Hmmm... NASA should do a 'contes' on earth, they have an engineering model of the rovers if i am not mistaken... Just let i do a mission in some desert, then a scientist in a suit, and compare what they accomplish in a given time...


One more thing: HELICOPTERS? you thin that'd be possible in such a low pressure?

#3472 Re: Planetary transportation » Airplanes on Mars » 2003-12-21 02:00:10

Wasn't that one of the proposed (er...) relatively cheap parrallel missions NASA plans to do, while concentrating on their 'bigger' mars stuff?



(EDIT: Um... Mars Scout, was the word i was looking for. They proposed a plane too for these missions, but it didn't get chosen... )

#3473 Re: Not So Free Chat » Holiday Wish List - ...Cosmic Style » 2003-12-21 01:57:12

Slowly coming down towards Mars, by space-elevator... No *That* would be cool...

And visiting a planet in a more central part of our Milky Way... You'd see much more stars than on earth...

#3474 Re: Not So Free Chat » Panel finds little concensus on space policy - No vision? » 2003-12-20 05:25:28

Sigh...
Houstonchronicle.com

The good news is: Zubrin gets quoted again smile

And this one... Hmmm... They want 'realistic' missions...
