A post from Andy Mcsorley on the project constellation site makes note of a past study from Caltech called 'Mars Scheme' back in 2000 called the Z-5.

While this may not be the start of AI it is in the right direction for Human and Machine interfacing in future missions.
I find it interesting to see the use of a segway for mobility.

#29228 Re: Human missions » The need for a Moon direct - and sustainabilty program » 2004-08-23 05:51:24

I am reminded of where this needed to be going from an article that was writen by Jeff Foust titled Moon, Mars, baseball, and football.
http://www.thespacereview.com/article/181/1

In that it was a very good analogy of what needs to be done to achieve both goals of going to the moon but to stay and of how to do the Mars direct or other configurations of any planned missions to Mars.

For the Moon do lots of small but successful steps very often for the moon.

The nations of old that use to fight amongst each other have seen what democracy can do in terms of world power not to mention the standard of living change by having done so.

As you noted, it should not just be scientist that get to go and to settle if you want the public even if it is a minority to get behind these billion to trillion dollar explorations ventures. You must portray the people that are doing this to the people that are left behind as common people and not the chosen few with the right stuff.

#29231 Re: Terraformation » Terraforming Venus - methods anyone? » 2004-08-23 05:38:05

Yes and No but mostly maybe. My thought was with regards to simular altitude and not of is density.

On the syphon I have a couple of thoughts one is to hang from orbit the container and a compressor like unit, where external atmosphere is brought in though an intake and compressed into the container to be hauled up when filled.
I was thinking that it could be shaped like a plane and have the wings covered with solar panels to power the compressor unit.

The compressor is simular to a car engine in that the intake of atmosphere which is sucked into a chamber, on the down stroke, then the intake valves closes followed by the exhaust  to compress the gas to the storage tank. The intake could be connected to a semi rigid tube that would be lowered into the atmoshpere from the orbiting vehicle. Probably miles long but I think possible. In either case use solar power and a electric motor to run the compressor.

Chill tank contents slowly and filter out liquids as they condense for later use into individual tanks.

If anything becomes of the xprize I hope it maybe a scare to the Big guys on the rocketry block and Nasa. For if any achieves orbital status, look out for private industry may soon to follow.

May if we wait long enough India can help with one of the vehicles used as a derivative.
India designs next generation launch vehicle GSLV-MkIII, a heavier lift launcher that would meet the four tonne class communication satellite requirements, the new generation vehicle which would be developed by ISRO by 2007-2008.

Speaking of derivative vehicles How can India do this when we can not even get started.

Also if we are looking to Boeing for solutions we may need to look further.

Well if you were looking for the Boeing first launch of Delta 4 Heavy rocket to be the next in possible shuttle replacements, it has been delayed.

I do not see that any problem other than Earth has a lot more atmospheric drag that a planet like venus does not.

Sorry Cindy, if I chose the wrong word with hubble but that is how it seems with how Nasa is viewing things.

#29240 Re: Human missions » The need for a Moon direct - and sustainabilty program » 2004-08-19 12:29:05

In Many of the discusions of topics we come back to what did the president mean by first the Moon and then beyound. To use the moon as a stepping stone to space.

To sustain a Moon project does this mean a base, colonization and or can it be one shot after the other with nothing permanent ever built.

We can keep looking a startup cost as well as the long term cost but are they really what is important to exploration.

If we go to the moon should we be looking to develope self sufficiency and less dependence on Earths resources.

Should the moon be the next Launching pad to beyound?

The questions keep coming or going and even Nasa is looking for information as to what is meant in the commissions report.

#29241 Re: Human missions » Hubble mistake - Action needed » 2004-08-19 12:10:50

Tell that to Nasa for if they could understand the importance of optical photo's then they would have been designing in that feature into the new telescope rather than not.

We talk a lot about what Nasa could be doing and then we find out that Nasa is doing a lot of unrelated Space activities.

Nasa definitely needs to be stream lined for space activites only.

The module test, at the Satish Dhawan Space Centre at Sriharikota, was the third and last one conducted by the Indian Space Research Organization (ISRO) using a helicopter.

The SCSU students are participating in research to help NASA minimize the negative effects of prolonged weightlessness on human bones.
NASA's land-based and space studies already show that bone loss varies greatly from astronaut to astronaut. Some experience little-to-no loss, while others experience significant bone loss

#29246 Re: Human missions » MarsDirect or Mars Sustained ? » 2004-08-19 10:15:13

Going to the moon to practice yes is very different as compared to Mars at least it has an atmosphere.

Soil type on the moon versus Mars are not even of simular mineral oxides. I do not see much research on the moon leading to any developed items for Mars.

The moon has its own unique research reasons for going back to it. One is simply to finish where we left off in our search for knowledge on planet formation.

As for on the billing side of the budget unless Nasa learns how to lower the cost of doing space they stand to lose a lot more than there budgets.

All the more reason not to get to comfortable with an enclosed evironment without being in a protective suit less helmet but ready to place one on in a moments notice of trouble.

#29248 Re: Human missions » MarsDirect or Mars Sustained ? » 2004-08-19 08:56:45

Actually we have lived off the land for centuries but those were of liveable condition. We have lost much of what is instictive survival skills to be redeveloped again for the Moon or for the Mars current environments. That is partly why the analogous site for the Mars society are in the romote regions of Earth. Taking advantage of the near Mars climates, soils, lack of water trying to simulate hostile atmospheric conditions by forcibly using space suits, sealed habitats and near rover transportation style vehicles

#29249 Re: Terraformation » Terraforming Venus - methods anyone? » 2004-08-19 08:11:28

If we were to get a ship into the lowest possible orbit and to lower a syphoning tube into the atmosphere that is connected to a pump and storage system at the ship. One could start the process of not only teraforming but also for provide the ability to self sustain themselves with less support from earth.

#29250 Re: Human missions » Cheap heavy launcher - can it be done at all » 2004-08-19 08:07:09

Most design work and workers usually do not care about cost of parts or of labor to make items. There usual goal is to just make it work and that it is someone elses problem for cost. The only way to change that mind set is to reduce the available design funds. Forcing the designers to finally give a care.
