#1 Re: Human missions » Is gravity really that necessary for a trip to Mars? » 2007-04-11 08:55:36

I like the idea...
for a novel that is.

It probably wouldn't work in reality, but in a novel yes.  You could make Mars a society of liars, cheaters, swindlers, and scoundrels.  It would all be based on that one lie told centuries ago...

How tragic...

#2 Re: Planetary transportation » Martian Gashopper Aircraft » 2007-04-01 12:24:50

I think a dual mode craft (VTOL/Horizontal Flight) is too complex.  They should try the gashopper concept with a ballistic hopper first.  If that works move on to the dual flight mode.

#3 Re: Human missions » Shouldn't there be more focus on surface mobility? » 2007-01-14 19:30:47

Michael,

I give you credit for not backing down to GCNR's first post, but come on man, don't make him shoot you down time and time again.

Now, about long range mobility.  We don't need one super-rover that can circle the globe on one tank of fuel -- and please don't ask GCNR to prove it.  The 500km range rover has been well researched, so why don't we see what we can do to extend it's range.

1)  You can have it tow a tanker trailer.  Because of the added weight of the trailer the rover will be less efficient of course, but with a plentiful fuel supply at the base it can be readied at a moment's notice.

2)  You can plow trails as has been mentioned before.  This will save travel time and wear and tear (except on the plows) more than increasing range, but it should make the rovers a little more fuel efficient.

3)  This is my favorite -- Bring along a few robotic fuel production stations and place them hundreds of kilometers from the base.  They can slowly fill their tanks using solar, wind, RTG or any available power source.  The visiting rovers can drop off excess water and fill up with oxygen and fuel.  The down side is that without a lot of power the stations will fill up very slowly.

Herm Goes to Mars (continued from page 12)

He spent six months flying through space
To begin the earthworm space race.
The transit was boring.
He spent his time coring
Through red dirt inside a glass case.

At last landing day did come near.
The ship might burn up Herm did fear
If they came in too low.
Past the planet they’d go
If they skipped off the atmosphere.

The ship was blazing like crimson
This landing felt like a hard one
But they came down just fine,
And with Herm they would dine
On veggies grown from the garden!

You forgot the last option:

3) No!  Definitely not!

I admit I haven't researched the process much, but it seems a bit too energy intensive and gives little immediate returns for a mere manned mission.  Including it in a colonization effort makes more sense.  I'd add a test model sometime after mission 3.

#6 Re: Human missions » The 1st woman in space -- ever » 2006-11-02 21:31:11

Umm... yeah...
...
...

I was just joking.

I love sarcasm online.  Someone always takes it seriously.

#7 Re: Human missions » The 1st woman in space -- ever » 2006-11-02 18:33:58

It's a good thing the Russians didn't put the first woman in space decades ago.  That would just be wierd...

But hey, I think it would be really cool if she went up twice.  The publicity the trip would generate might be better for the private space effort than $25 million dispersed among a gajillion schools.  A second trip would encourage space tourism investment, etc.

#8 Re: Human missions » Privately Funded Mission--Get On With It! » 2006-11-02 18:10:48

Robert,

How in the world is space traffic supposed to keep up with the air traffic of the early 1900s?  There are no destinations.  Early airplanes could take mail back and forth between cities.  No interplanetary mail for us.  Air travellers back then shaved hours or days off their intercity travel.  No space cities out there for us.

Once we get stable bases or colonies on Mars or the Moon private interests will have a market for their services and space travel will really take off.  We need governments or super-rich space philanthropists to start those bases and colonies.

I do agree that the pledge idea just won't work.  Maybe if a multibillionaire got the ball rolling and actually built some hardware...

#9 Re: Human missions » Ares and Ares » 2006-09-14 19:06:29

I think you guys are missing GCNR's point.

Sure, for the long term, when you have already built mining ships big enough to gobble up asteroids and use every element they contain, then and only then, will asteroid mining be more efficient than planetary mining.

I'm sure that GCNR would agree that small scale asteroid mining should be experimented with, but entire colonization programs shouldn't be based on it.  And, we shouldn't delude ourselves into thinking that it will become cheap anytime soon.

#10 Re: Human missions » Save-A-Stage » 2006-08-16 23:54:12

Since equatorial countries are possibly unstable, construction and maintenance of a sled up the side of a mountain is very costly, and speed is more important than altitude...Why not build the sucker on level ground in Arizona?  Cheaper, stable, and...not high...

IIRC most rocketplane designs need to be towed or refueled in midair.  Just get them up to speed on the ground, fully fueled, and then whoooosh!  This might solve the refueling problem or it might be worse.

What do you think?

By the way, does anybody know what happens when you go supersonic at ground level?

#11 Re: Human missions » NASA Exploration Roadmaps » 2006-07-04 13:06:26

I was shocked to see the name Ares on this VSE thing.  I truly thought the Mars part of Moon-Mars was all hot air, but this name is promising.  I sure hope they carry through and use the Ares to send explorers to its namesake.

#12 Re: Human missions » Next Shuttle Launch: Late 2006? » 2006-07-04 13:00:59

They made it!  big_smile

I haven't watched a live Shuttle Launch for years.  It's still pretty exciting.

#13 Re: Martian Chronicles » Black Mars alt-history » 2005-08-13 00:14:17

It sounds like a good story, Bill.  I love alternate history stuff.

#15 Re: Not So Free Chat » Mars Frontier Novel - New web location » 2005-06-12 18:38:49

Just finished volume 10.

It's still kind of dry, ok, really dry.  But hey I like getting your view of the big picture (govt., Macro-economics, etc.).

Keep it coming.  smile

#16 Re: Martian Politics and Economy » Who should first go to mars - Who should first go to mars. » 2005-04-30 10:14:49

Pilots are fine, but most of the mission will be on the ground.  Also, the space ships will probably be able to fly on autopilot, so a pilot would only be used as a backup.  A mechanic would be more useful.  This would be the person who knows every inch of the equipment, both space and ground equipment.  Assuming the goal of settlement, I would send builders, farmers, and scientists.  They would be people wanting to start families there, as well.

Sending only technicians and forcing the real scientists to stay home is almost as bad as only sending robots.  It wouldn't cost more to send a scientist, but obviously a scientist can do much more if he/she is on site.  The simple inefficiency of the time delay in communications is enough to dismiss your idea, srmeany.

I don't have a problem with the wealthy going.  If they pay then great!  This will inject cash into the system and show the public that Mars is open to anyone (with the means).  It will also set a legal precedent for private Mars ventures and stimulate the private sector.

#17 Re: Unmanned probes » Where Do You Stand? - Decision time is now about the future » 2005-04-29 15:21:33

I agree with Shaun.  There is no choice.
The VSE is a nice idea, but has an unrealistic timeline.  I doubt the CEV will be completed on time.  And, I doubt the program will get much further than that.  This is based on the assumption that no other president after GWB will push the program faster, of course.

Since the VSE will probably fail, I have to support the extended missions of all robotic probes and Hubble.

I vote for more overall funding for NASA or an X-prize style system open to private enterprise.

#18 Re: Not So Free Chat » Multi User Mars Simulation Game » 2005-04-29 14:54:05

I would love to see a game like Civilization done for Mars.  Its sequel, Alpha Centauri, is close but a little too far future/sci-fi.

#19 Re: Not So Free Chat » Mars Frontier Novel - New web location » 2005-04-23 10:15:19

Still reading...

Everyone still sounds like an ultra-nerd, but here I am reading it.  So what does that say about me?  big_smile

#20 Re: Not So Free Chat » Political Potpourri IV - Continued from previous » 2005-04-19 09:09:52

Politicians manipulate the perception of the threat rather than the threat itself.

I think that is what she was getting at.  Right, cindy?

#21 Re: Not So Free Chat » Political Potpourri IV - Continued from previous » 2005-04-19 09:07:34

9/11 unnerved me completely

I don't know.  Maybe I'm just wired diferently than you, but I remember thinking on the day of the attack that this was something that couldn't be repeated easily.  I figured that airports and public transportation would simply tighten its security and prevent more of this sort of terrorism on its own.

Did it really freak you out?  Like did you go buy a shotgun and a gasmask and all that?

#22 Re: Science, Technology, and Astronomy » Olympus Mons is Alive! - The volcano is probably still active. » 2005-04-11 13:11:34

According to the book "A Travellers Guide to Mars," Olympus Mons has been active within the last 1% of Martian history.  The author has come to this conclusion using crater counts.  This pretty much means that it is still an active volcano and can blow at any time.

Any thoughts?

#23 Re: Not So Free Chat » New Spanish law to require - that men do housework » 2005-04-08 12:59:45

But seriously, how do they expect to go about enforcing something like this without it becoming a farce? And if they don't but are just trying to make a point, that kind of undermines the entire basis of law.

Here's the answer.

Failure to meet the obligations will be taken into consideration by judges when determining the terms of divorces. Men who refuse to do their part may be given less frequent contact with their children.

If I understand U.S. law correctly, it will be like unfaithful spouses.  In a divorce, if a spouse has been sleeping around he/she gets less custody/visitation to the children, right?  Sounds fair and enforceable to me, if the govt. only steps in during a divorce.

#24 Re: Not So Free Chat » Capturing Mars - Let the imagination run free... » 2005-04-06 13:45:56

After the two boys left, I detached myself from the boulder that hid me during their little ceremony.  Had they dicerning eyes they could have seen me, but mother knew how to hide me -- even in plain sight.

Walking up to the wall of names, I felt the sacredness of the site.  It was surprising, for I had thought that Mars loved only me, Her firstborn.  But she had surely blessed this site, as she had blessed me.

What was I to do now?  As I read the names of those who called themselves true Martians, I recognized some whom I hated.  How could I dispose of them now, now that Mars had touched this place with Her spirit.

Were they Her sons and daughters as well?  As I pondered upon these new discoveries, the rage that had possessed me earlier subsided.  Perhaps I was an only child no more.

All of a sudden things became clear.  I now knew why She had led me to this spot -- why She had urged me to follow the youngsters, instead of proceeding directly to destroy the settlement.  Her children, my brothers and sisters, lived there!

I paced back and forth in front of the smooth stone for hours, soaking into my soul the names inscribed there.  Many of the names brought memories to my mind, sweet memories of childhood.  Smiling faces, loving embraces, laughing voices.  Sweet memories.  I didn't know I had any, but She helped me find them, deap within.  Sweet memories, sweet mother.

Suddenly I found myself staring at the green bubbling cancer that grew upon Her skin.  Domes of vegetation fed the cancer while it's tendrils grew beneath the surface, meandering mounds of ice and regolith their sign of infection.  All the parasites scurried within.  Why had she saved the settlement?

Oh yes, my new brothers and sisters...I must meet them and show them Her love.  Then we would all remove the cancer.
