(EDIT 27 dec: And it's up again!, guess they just removed the 'Express' tag...)

#3478 Re: Life on Mars » Are there people against contamination of Mars? » 2003-12-20 03:45:31

So let's assume for a moment that it turns out that Mars is the only non-Earth nearby source of life. If we destroy the whisp of an ecosystem that exists with terraforming, we'd forever loose a wealth of information on how life comes about and where it can survive. We'd be back to working with an example of one, and necessitate yet more speculation and guesswork.

That's a very good point. Problem is, when can one *definitely* say there is *no* life... If you don't find it, it could be hiding. How long should one keep searching...

#3479 Re: Life on Mars » Mars Sample Return - Threat of back-contamination » 2003-12-20 03:38:13

Official explanation:

"The crash of Polar Lander, coupled with the loss of NASA's Mars Climate Orbiter a few months earlier, triggered a major overhaul of the agency's strategy for exploring the planet.

The loss of Polar Lander was traced to an undetected software error that caused the rocket to shut down during descent. The Climate Orbiter missed Mars because ground-based experts mixed English and metric measurements to make critical navigation calculations.

Investigators blamed the lapses on underfunding and a compressed development schedule that didn't provide enough people to work on the programs or allow enough cross-checking for errors. "

A celebrity in the science world is Neil De Grasse Tyson, he works in the new york observatory, published *a lot* of papers. Very interesting guy... One of the few African American people that made it into the scientific elite.. Comes from the Bronx, got 'crazy' about the stars after one quick look through a telescope... and now he's one of the world's most famous astronomers.

Try to google for his contact info...


BTW Im not an X-Prize contender sad  but i'm following the news, and i saw your entry into the race. Good luck!

#3481 Re: Civilization and Culture » FlyToMars.com In Development - Volunteers Needed » 2003-12-20 03:22:04

Sorry, count me out, then... I'm not into web-design and all that.
interesting idea, though.

#3482 Re: Not So Free Chat » Combover » 2003-12-20 03:20:20

Yes, show it. He surely is a Brainiac!  (That's a compliment...)

#3483 Re: New Mars Articles » Horrible reporting on Beagle 2 - Rueters article is wrong, wrong, wrong » 2003-12-20 03:12:55

Hi, Borrowma, thanks for pointing this out, and of course: welcome to New Mars!

Weird, Reuters making all these obvious mistakes... I guess Reuters misinterpreted the fact that Beagle 2 has the highest mass/science ratio compared to other probes...

As explained here

That 'rocket' nonsense is a bit harder to defend, though... What were they thinking?

#3484 Re: Unmanned probes » Dust storms could spell disaster for probes - several small storms starting » 2003-12-20 02:52:44

Christina, we're not mocking...

We're just fooling around a bit. Beagle 2 is a fantastic piece of machinery, built on a shoestring budget.

I surely wish the team all the success they can get, they deserve it.

#3485 Re: Terraformation » Blue about Green vs Red? » 2003-12-20 02:44:04

I'll just jump in and out to say that, indeed i related klingons with male... Believe it or not, but i never saw a single episode with klingons in it (except that 'civilised' guy)

I do not have tv...

ok, back to terraforming...

#3486 Re: Life on Mars » Will Beagle 2 find signs of life on Mars? - Poll » 2003-12-19 16:00:39

Beagle 2 will look for tell-tale signs o life. Expectations are high. What do you think?

#3487 Re: Other space advocacy organizations » Life to Mars Foundation - Well, Who are they? » 2003-12-19 15:53:51

Here's more info...

Spaceref.

But i read an interview with Elon somewhere in wich he said the project was on the back burner... He's now concentrating on XCOR.

His reasoning went something like: "i wanted to do this 'life on mars' thing, but found no launcher that was affordable, so i decided to go and build cheap launchers instead!"

So, in the long run it might be better to have a cheap launcher, that way third parties can have a go at cheap Mars missions...

#3488 Re: Life support systems » Current experiments on algea, lichen etc.? - Anybody doing this stuff » 2003-12-19 15:39:29

There's been talk about doing tests with pressure vats containing lichen, algea etc,

... to gradually change the pressure and atmospheric composition, radiation... towards Mars analog state.

But have there been real tests done, so far?

(Important to know how to build a 'minimal requirements'  greenhouse, capable of- oxgen/soil/compost generation...)

#3489 Re: Terraformation » Blue about Green vs Red? » 2003-12-19 15:34:49

Good. Anyway it would be technologically impossible, there's not enough bandwidth to carry all that chatting about the neighbour's new ugly dress etc.  :;):


(I'm kidding, REALLY!)

#3490 Re: Terraformation » Blue about Green vs Red? » 2003-12-19 15:02:06

the "loud, burping, smelly, crazed Klingon-slob types" is the ideal to shoot for.  Give me a break.

You mean you only want women in space?  tongue

Actually, that burping and smelling is because of the constant space-sickness, really!

#3491 Re: Unmanned probes » Dust storms could spell disaster for probes - several small storms starting » 2003-12-19 14:15:50

I wonder if that scientist (Prof. Pillinger) really doesn't consider it a "big concern," or if he's being diplomatic and trying to ease anxiety.

Well, you know the British, keeping the stiff upper lip and all that... big_smile

#3492 Re: Civilization and Culture » FlyToMars.com In Development - Volunteers Needed » 2003-12-19 14:04:01

Do you mean giving tips and advice on HTML, Java, Flash and all that?
Do users have to build a homepage from the ground up, or do they get a 'framework' to 'fill in?'

(i'm not a programmer, sorry for the vague terminology)

#3493 Re: Civilization and Culture » Free Speech on Mars - Theme of BCML Corp. Time Capsule 2006 » 2003-12-19 13:53:21

BTW, X-Prize, sub orbital-tourist stuff is quite 'cheap' if you see John Carmack's numbers for his armadilloaerospace.com vehicule: (bold text is my doing)

"Just building the vehicle costs less than $100k, most of the money is in building multiple iterations of everything as you figure out exactly how you actually need to spend the money:
$ 6k 850 gallon fiberglass tank
$ 2k High pressure carbon fiber pressurant tank and regulator
$ 1k Honeycomb composite panels
$ 5k Aluminum fabrication for cabin
$15k Redundant parachutes, drogues, drogue cannons, releases
$13k Fiber optic gyro based IMU
$ 8k Unrestricted (supersonic / high altitude) GPS
$ 2k PC104 systems
$ 5k video, audio, and data communications
$20k Engine machining, catalysts, laser cut plates
$ 5k Plumbing, valves, etc
$ 5k Fastblock external insulation
For powered landings instead of parachute landings, delete the parachutes and add:
$ 4k Laser altimeter
$ 4k Wire rope isolator landing gear
You could trivially spend an order of magnitude more by just using "space certified" versions of everything, but the important point is that standard industrial versions of many things are perfectly adequate. In many cases, todays standard industrial practice is far ahead of the best that could be done at any price in the early sixties.
This is all with free labor for assembly and testing, but that is still only a couple hundred man hours for a full vehicle. We are expecting to destroy the first vehicle in some (unmanned) testing mishap along the way, and build another one mostly from scratch. That will take less than two months, depending on lead times for some items."

That, and the fact that his site has almost all the step-by-step instructions how to build your own craft... You don't need no 'real' rocket-scientists, just some good engineers... just read the instructions  big_smile  how to build your own

#3494 Re: Human missions » Space groups Unite - Stop acting like children » 2003-12-19 13:47:05

As Bill White pointed out, ESA has a -tentative- timeline to a manned Mars mission...

Nasa *had* some stuff on their site, but pulled all that, recently.

This can mean 2 things:

NASA is out of the race

OR

NASA has BIG plans, but want to keep it hush-hush. (but there would've been leaks by now, not?)

Also notice ESA goes to the moon (in their plans, anyhow) to do a shake-down of their hardware in preparation for the big jump...

Also notice, today ESA has no manned flight hardware at all...

#3495 Re: Civilization and Culture » Free Speech on Mars - Theme of BCML Corp. Time Capsule 2006 » 2003-12-19 13:34:43

How can a company like mine introduce an initiative like this to any Black African country on the Equator?

I'd guess it's mostly politics...

Try to contact universities, science minister, or even the government by e-mal, or more 'impressive': written mail (looks more personal, everybody can fire off an e-mail, but real paper-letters, esp. from far away, stress the point you're serious...)

Ask for their opinion, or suggestions... I think local educational centres and busines would be ecstatic to know someone would want to do this...
Try to get your ideas submitted in big conventions, etc...

But as Bill White points out, LEO is quite a saturated mrket, so you'd either have to go directly for GEO (Difficult and expensive) or suborbital, X-Prize stuff... (Cheap and a good starting point to learn the ropes...)

#3496 Re: Unmanned probes » Dust storms could spell disaster for probes - several small storms starting » 2003-12-19 13:09:26

Good news?

BBC Online

Prof Pillinger says there'll be no problem (at least for Beagle 2)

"My information is very much that it's not going to be a big concern"

Have to say, i don't like that 'big'...

#3497 Re: Civilization and Culture » Free Speech on Mars - Theme of BCML Corp. Time Capsule 2006 » 2003-12-19 12:21:00

Dar-es-Salaam... Maybe some X, or rather Y prize people would be interested. The investment should be lower than the big infrastructure used by NASA et al, but of course legally exporting rocket-science is always difficult. An Armadillo II type vehicule could be built in Africa, for a reasonable price, there's a lot of info freely available on the 'net, lately, so maybe this is the time to do something like that (yea, i'm a dreamer!)

Is there something like ESA in Africa (i mean universities and industry collaborating on bigger projects...)
If not, why (not)?

#3498 Re: Civilization and Culture » Free Speech on Mars - Theme of BCML Corp. Time Capsule 2006 » 2003-12-19 11:14:52

Why shocked? Is that so outrageous a comment?

Maybe b'cause i said the current help-programmes are belittling. It might be in good faith, but they solve next to nothing. Give a man a fish etc...
Africa has been plundered and politically messed up for centuries, is still recovering from that past... It is a continent with a lot of potential, and it would be in the interest for *all* humanity to tap those resources for the deployment of the continent and the people itself. A prosperous and happy Africa, proud once again, would ease a lot of tensions on the political agendas, i'd think.

#3499 Re: Civilization and Culture » Free Speech on Mars - Theme of BCML Corp. Time Capsule 2006 » 2003-12-19 11:00:58

On Bill's 'idea' the problem with the location is that it's percieved as non-stable... politically. Too much wars in the recent past, no westerner big-money guy would want to invest in large-scale launch infrastructure, if not give some serious guarantees the region is politically stable.

Of course, The African countries should not have to wait for foreign bankers...

#3500 Re: New Mars Articles » Letter To Beagle - Find Life? » 2003-12-19 10:03:09

Anybody read Stuart Atkinson's Letter to Beagle?

He claims Beagle will find life. Bold predictions, but if one probe can do it, it will be Beagle.
