My prior short posts re space utilization involving human spaceflight

Per my immediately preceding post here, realizing that I don't seem to have my prior comments put on on Facebook for the "Human Spaceflight" conference here in my blogger jedcstuff blog, here is my summary comment to NASA regarding my efforts to contribute to the "human spaceflight committee" invitation for Facebook comments:

"Probably you have already decided that America's next effort in space is to just be for the adventure of going to Mars and returning with some rock samples, an Apollo for Mars, since Apollo was such an attention-getter, providing immense money to corporate businesses, and so quickly ended, no follow up required.

So I will start with the brief descriptions which I prepared to post on Facebook today in effort to help you, as if you actually really wanted my help:

1) If the purpose is to prepare for a long term connection with Mars, then an initial goal of establishing an outpost on Phobos, the inner moon of Mars, and building a dual pulley anchored tether space elevator there to drop to close to an atmospheric drag area in Mars' atmosphere, then all we have to do is the low delta-vee trip from earth orbit to Phobos, then use its considerable mass and orbital position to have dual-belt pulley space elevator technology to get to the upper atmosphere, so from there down to Mars surface and back is all the propulsion energy requirements, perhaps entirely winged flyable for round trips thereafter, connecting to the low end of the space elevator, from the surface of Mars.

But if there is real interest in the application of space for the benefit of civilization, beyond the stimulation of technology and corporate business, here are some more suggestions which were also prepared per the request by email to do comments, such as on Facebook, which I quickly found had a maximum of 1000 characters for an entry.

2) If the purpose is to go to the Moon, then we need a better purpose than last time, which was to be able to set up missile launch bases there too if the Russians were doing that. That was a tremendous technology stimulant and was a lot more fun than throwing bombs at each other, too. The Moon is a potential high source of construction materials for things in Earth orbit, from GEO to L-5, takes much less energy to lift from the Moon to those places than to lift from the Earth's surface. So early return to the Moon might be for establishing experimental materials collection and processing facilities, particularly destined for processing in zero-gee enroute to points of construction usage. For lots of ideas read in the easy form of sci fi adventure, see The Ark of 1984's Future https://www.smashwords.com/books/view/2824 and The Torus Cities Ice Shields Returning Home https://www.smashwords.com/books/view/2499

3) If the purpose is to develop long term nearly fully self sustainable habitation technology for space, support conventional automated launch vehicles, and support private development of conventional technology manned medium scale access to LEO, then we might consider the completely automated launch and basic assembly of the classical mile-diameter wheel type space station for 200-1,000 people, built of modules designed as both specialized prefab habitat modules and for use as their own fuel tank during launch by a reusable flyback engine module and supported by an airbreathing flyback booster, all teleoperated launch and docking into the circle, before the first person arrives, thus a low risk and cost activity.

4) If the purpose is to explore potential means for accessing space resources in a full scale way, then it makes sense to explore the long ignored "space escalator" type concept for continuous ground to GEO high efficiency electrically powered transportation, resembling a filled-in Orbital Transfer Trajectory shape synchronous electrical motor between equatorial earth surface and GEO above the opposite side of the planet, the quasi-elliptical structure enclosing hard vacuum and inductive tracks along which motor armature mass segments travel at twice the orbital velocity to centrifugally press outward on the structure to support the equal stationary structural mass of the motor's stator elliptical perimeter, and use inductive drag against the upward armatures to drag captive spacecraft from ground to GEO, by which Solar Power Satellites are built in GEO, along with Total Recycling Plants and GEO spaceports for very large scale rocket vehicles to Mars and elsewhere. http://www.scribd.com/doc/14090773/The-Space-Escalators-Unique-Potentials

I doubt you will carefully consider what I have to say any more than the National Commission on Space did when I testified before them on a similar subject in 1985. It is easy to continue to ignore me into oblivion, won't take much longer. But I have done my best here in the few words allowed. Anyway, this is easier than giving a speech in front of all those people, wearing my best interview suit, like in 1985 in Golden Gate Park in the museum's huge auditorium, now torn down and something else built there.

There is a big difference between playing a political-business game, vs going toward that which helps mankind and civilization's best interests. The kind of pay they provide is quite different, too. Whatever, I wish you the best of luck.
