#26 Re: Space Policy » Bush Sets Wrong Goal? » 2004-01-15 09:31:56

IMHO, I see Bush's plan as a nice comfortable compromise that is probably about the best we could actually see.  Also, this plan seems pretty open ended...   But I do believe we do need to go back to the moon, if not for anything else then some basic testing of the equipment we will use on Mars.  Since, they will be much closer, incase something goes Tango Uniform.   

We have to learn to crawl before we walk, and we have issues with even getting high enough to crawl... 

Also...  I don't think we are ready for Mars yet.  Until we can get a 100% rate of getting probes there....   we can't even do that yet...  I think that makes any mission a bit of Russian roulette.

Is it just me or does the darker rock in that nice color photo look basaltic?

#28 Re: Martian Politics and Economy » A New Vision for Mars - Include Ordinary People and Their Kids » 2004-01-07 10:18:24

To Colonize Mars to start off with we would probably need a support system similar to Antarctica.  You would have the Scientists doing their thing..   Also the support staff.. and such..  at least 10% of the staff would be support of some kind.  Preferably those that are trained in multiple things.  Just a thought..

#29 Re: Human missions » Space Tours - for the rich » 2004-01-01 08:40:15

Just a hunch too, some companies maybe being quiet in lieu of possible industrial spying.  For some of these companies the 10 million and the press would be a major 'booster' to their productivity and sales.

#30 Re: Planetary transportation » Airplanes on Mars » 2003-12-29 18:03:03

I think this would be a thing to use on a Manned mission.  Especially something like a UAV or mini UAV.  Something reminiesent of Global Hawk or Predator, or even the small thing the Army uses might work well.  With a lower version of ASARS (Advanced Synthetic Aperture Radar System) imaging, but even an electro-optical system might work well.  It may be possible to use ASARS in a sandstorm, but not sure..  I digress

#31 Re: Human missions » Post Kitty Hawk Momentum Shifts to Mars - Marssociety headline » 2003-12-29 16:33:59

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.

I agree, no reason to rush anything.  Also, my spin on things.  Good Policy evolves, it does not happen overnight.  So, we should be a little more patient.  I don't have a lot of Faith in Dubya, but I am willing to let him Suprise me.  We need a good solid feasible goal, that is reachable within 8-10 years at a reasonable cost and without a major need for technology.  Then we can branch out from there.  Personnally I would settle for the moon in the short term for a chance at Mars in the Long term.  With the success rate of craft going to Mars, I wouldn't send a person their till that improved dramatically.

#32 Re: Water on Mars » 'smoking gun evidence that water was on Mars' » 2003-12-25 15:28:36

Yippee,  I love the people that are going to Mars with new science, opposed to trying to find life.  While try to find life is cool, and neat,  I enjoy the real science...

#33 Re: Not So Free Chat » Jeopardy - Jeopardy » 2003-12-15 10:50:53

I am so upset.....


I was watching Jeopardy and the President just HAD to have a press conferene..  where does he get off..

#34 Re: Human missions » Not enough optomists - hard to predict 25 years out » 2003-12-15 10:49:39

I think that the we will go into space, but opposed to pessimism being a problem, I would say it would just be apathy. 

We will back to the moon, we will go beyond the Moon, short of some massive extinction killing us all off.  It's just when..  Definitly by 2100 we will have a man on Mars..  We all know we could be there in 10 years, or could have been there 10 years ago.   

There is no new technology needing to be developed.  The two hurdles are Policy and money.  I am waiting to hear what Bush says on Wednesday.  It may remove one or both of those issues!

#35 Re: Human missions » Not enough optomists - hard to predict 25 years out » 2003-12-14 10:50:41

I do not intend to start a yelling match but physicists from MIT and NASA thought other then the amount of explosives used, that the movie was accurate..  maybe a bit unlikely, but definitly possible.. 

The 25 years between lets say 1953 to 1978-  The Air Force was completely different.   the fastest plane in 1953 was the X-2, fastest Jet was the F-86.  the B-36 was finishing up development with the B-47 on the Horizon.  simply radars were being developed.  There still was dogfighting..  No ICBMS.  NO Communications Satellites,  no digital communications, everything prettymuch vacuum tube based.

1978-DSCS satellite system and Milstar deployed
Advanced avionics and fly by wire with either the F-15 or F16 respectively.
B-1 being developed
current fighter bombers include
f-106
f-111
A-7
A-10
B-52

Full line of ICBMs
GLCMS

on the verge of Satellite defence system

Full digital communications including the DEBB (europe)
etc
etc
etc,

ie completely different Air Force,  6 years old instead of 30 years old.

#36 Re: Human missions » Wi-Fi on Mars - Lots of great possibilities » 2003-12-12 19:30:31

embedded wifi could be a good idea.  Especially as the technology increases alowwing for higher throughput.  The standard for Digital voice is an 8 khz PCM encoded digital signal that takes up 64 kbits/s  so it would leave bandwidth for suit telemetry and maybe a linkable heads-up display or a cam back to base to record movements.  I could also see this used with a wifi connection on a rover then either a sat-link or LOS link to main base.   By that time their should be a few geosynch sats on orbit, but I digress.

#37 Re: Unmanned probes » Nozomi » 2003-12-10 10:01:32

Well, the probe went MORE THEN 300,000 MILES..  maybe the timing chain broke..  thats always the killer for Toyota pickups..   tongue

Well,  I think the Japanese will be able to make a comeback,  unless the have lost Hope.   pardon the pun..

#38 Re: Human missions » The Moon Landing on the cheap » 2003-12-10 09:46:39

-Since you can't use GPS beyond the orbit of the GPS satelites (their signals only point down at Earth), can your ship really be precise enough time after time with the small margin of error? Propulsive capture permits much more generous orbital insertion and course correction flexibility.

10,800 miles is their orbits

precise flying to hit the atmosphere at the right angle does not strike me as that difficult with advanced computers, especially if one uses GPS (and we will need a GPS system for Mars eventually, anyway

Part of GPS position is based off of the refraction of the L-Band radio waves in the atmosphere..  never heard of many space based uses of GPS,  most of those systems have their own their own navigation systems.  GPS has a three fold purpose.  The two that would effect things like this is obviously it's positions systems,  and it's timing distribution of UTC. 

Shuttle C is a great launch setup, and is an upgradable launch setup.  With the possibilities of evolving SRBS and the tank, with the proper equipment.

#39 Re: Human missions » Not enough optomists - hard to predict 25 years out » 2003-12-10 08:55:43

The year is 1953, the United States is a superpower, one of only two on the planet. The US has a modern air force

The US Air Force wasn't truely modern by todays terms atleast until the late seventies.  by the seventies the Air Force had point to point and spoke to hub Satellite communications, with various levels of encryption.  A fully developed fleet of modern aircraft to do just about anything possible in the air, with a fully capable logistics to back it up.  in 1953 the planes were basicly alightly faster versions of P51s and P47s used in World War Two.  I should know, since I am 20,000 feet below their battleground, aka Mig Alley.

? Discovery of Microbial life on Mars or one of Jupiters moon

Discovery of living Microbial life on Mars could pose more of a threat to future missions then many think.  Depending on how much the Greens unite,  they could stall almost all efforts to continue exploration of Mars.

? ? Discovery of Extraterrestrial technology

Yes, I agree with you, but I would not even wager odds on this one. 

?
? A threat from space, such as impact of a NEO object,

IMHO, we are ill equipped to handle such a threat, and unless we have a window of 5 to 10 years,  I don't see any sort of Heroic Armagedeon(sp) type ending.  Realistically we lack the technology and expertise to do it.  I do have the copy of the Air and Space Smithsonian at home that talks about the movie and said the only truelly unrealistical part of the movie was they didn't use enough explosives.   the rest was possible.......... According to physicists from MIT..


But, anyway, to get to the point...  big_smile   Being optimistic won't get as anywhere predictions won't,  without action, thoughts are thoughts.

#40 Re: Unmanned probes » Nozomi » 2003-12-09 15:40:29

Well,  I think Kudos are in order for the Japanese Space Agency.  Nozomi, while dubbed a failure, I believe it is miracle that they have gone this fair, with the failures.  I hope they take it all in Stride and put up something new soon.  The probe has had such bad luck, and they have done so well to get this far.

#41 Re: Water on Mars » 'smoking gun evidence that water was on Mars' » 2003-12-09 09:05:00

Brief terminology question:

How can a petrified and exumed "gun" be still smoking?

Cause it's that cool..  d'uh!  :-) 
Just because it's old it still likes Camels.
hmm, I would try to think up 8 more, but I can guarantee they would only get worse, and considering how bad these are....  I will stop.

#42 Re: Human missions » George Bush Jr planning on kennedy speach - mostly moon,  but as prep for mars » 2003-12-04 11:41:45

I'll keep my fingers crossed.  Hopefully we will make a return.  Maybe with China's plans some pressure will be evident!

#43 Re: Planetary transportation » Land propulsion - Tracks, or tires? » 2003-12-03 19:26:38

Rubber or synthetic base tires don't have to be Pneumtic based.  But I believe tires to be the best solution.  For lightwieght quick transportion an Axled tire setup would be the simplist and easist way to do it.  It also would be the most straightforward to maintain.  The more complex a system is, the more bugs that have to be worked out and more wierd and stange break situations you get into.  I am into Rock-Crawling.  This is a form of offroading that has a goal of going over obstacles that would be impossible in a normal vehicle. 

A convential system like this would also be nice due to the ability to CNC new parts easier.  The other thing is with tires of a synthetic/rubber base, the passengers will be very thankful the ride qualtity will be much better.  Unless you are driveing on ice, I don't see a need for stud based metallic tires or cleats. 

One last thing is minimal environmental impact.  a standard tire of some sort or deviation will have the lowest impact, then a standard track.  Anything Studded or Cleated will tear the %$# out of whatever you are driving on. 

Just my 2 cents.

#44 Re: Human missions » Martian Exports - What can martians sell? » 2003-12-03 19:16:02

I will do the same thing as Cindy, I am not going to read all the posts, and many seem to have drifted from the original topic anyways.

The Problems lies in making a cost effective export from Mars that will be able to be sold to consumers at a price that is worth buying in quantity and yields an attractive profit to the entity(company/country/organization etc) that is providing said commodity.

To get to the just of the point.  The biggest problem is transportation.  The cost per pound of transport from Mars to Earth is very high and somewhat risky, given the track record of probes succesfully navigating between Earth and Mars.   This suggestion has been brought up in other posts a while ago.

Media might be the best bang for the buck export from Mars.

Pictures, movies, etc.. would be the best bang for the buck.  Between one and three satellites orbiting mars that would have a high bandwidth capability(thinking at least T2 Range 6-7 Mbps constant rate).  News reports, TV shows (Discovery Channel Series exploring MARS) Super Hi res pictures and hyper accurate maps for students and enthusiasts as well as for Hollywood for Movies to increase their Realism and Accuracy.  Coffee Table Books and Lithographs, I could go on forever.  But this would be biggest bang for the buck probably for the next 20-30 years.  Then start doing a piece of Mars type concepts, a vial with Martian dust, a martian rock in a block of scrylic as a paperwieght. 

Until Minerals become very scarce on Earth such to the point that Supply and Demand raised cost to match the cost of transportation(which will continue to fall in a gently curve I imagine), it is just too cost prohibitive.  With the availbily of NEOs it's not feasible.  Once Settlement and Exploitation of Asteriods exist Mars will serve an important function as a base of operations and logistical support being millions of miles closer.  Of course there is certain space logistical issues that are in developement that could change all of this (a la Space Elevator) The feasibility of these projects is up in the air, but like many things, time will tell.  I firmly believe that with the right vision and right people their will be some sort of solution to this issue which would be a massive gain for Us for cheap access to Space.

#45 Re: Human missions » I have some questions » 2003-11-27 05:29:29

Like rxke said there is different types of valuable.  To a future space crew the deposits of most value will be ones that can be processed into core components such as water, oxygen, and fuel of varying types.  By the time it becomes economically viable and even profitable to mine on mars for consumption on Earth, NEOs will be taken advantage of, with their Rare Earth Metals variety and close proximity to Earth.. it wouldn't be that hard to snag one on fly bye and park into a Lagrange point for processing (L5?)... Of course that is many many many years away.

#46 Re: Science, Technology, and Astronomy » $300M to destroy hubble » 2003-11-26 04:20:37

This may sound dumb,  but how much would it cost to make a mount or umbilical of some kind to mount it to the ISS?

#47 Re: Human missions » No plans for Mars mission in near future - sketchy details » 2003-11-23 03:58:40

There has been high and low points in Space Flight and I would definitly put us at a trought of the wave of space flight.

What we need to grasp is a vision. 

This Vision needs to be agreed upon by a majority of people such that it can turn into something tangible. 

We are currently in a defeatist cycle.  The only major press given to space is based on disaster.  If something good happens it's back page news.

Maybe the culture problem with Nasa is a sampling of a larger problem overall.  How can we invigorate the people to want a space program, to make it a major issue? 

That is the question...   

I think it may stur a chicken egg debate though.  Public interest or new program.  If you get a new program it may spawn interest.  Without interest though it is hard to justify funding a new program.

If someone goes could they possible make some pictures or information .  I would like to see this stuff but it is a bit of a commute for me.. 

Thanks!

Why is there a different definition for dormant volcanos on Earth, then Everywhere else..  sorry.. my two cents..

#50 Re: Terraformation » Rapid Terraforming... - ...the most ambitious ideas? » 2003-11-22 09:25:06

no to be too cynical but terraforming mars to so that you will either die from skin cancer or leukemia?(leukemia cases due to nuclear radiation see hiroshima/nagasaki)  I thought the point is being able to walk outside, so trade a space suit for a nuke suit.. sorry..  Not to be offensive.. but I think there may be better ways.. more refined and slower..   But I have my doubts, if we can't control out own planets eco-system and atmosphere do you think we could control a rapid change of another from barren bordeling vacuum to breathable levels?
