Post technologies etc. for interplanetary transportation   Posted on: Thu Sep 29, 2005 5:16 pm
In the Latest News section it has been said that supposedly there never will be interplanetary transportation of raw materials like coal.

So I began to think about it.

The first I can think of is the way the CXV is designed to reenter and land. It is using a method which is in use when capsules return from space which return scientific films. t/Space or Burt Rutaan have said so as far as I remember.

Of course - in the case of the films the capsules will have been very small. But the CXV is large - it can carry up to six persons into orbit.

It will be possible to reduce the passenger capacity down to the pilot or to zero. This would mena that all life support systems would be removed due to uselessness - except that for a pilot.

This way sands, coal etc. could be delivered down to Earth from orbit.

The CXV-like capsule could land in water - like the CXV. In this case a standard landing region could be established and special ships stationed there which could recover the cargo very quickly. If the capsule is completely unmanned it could be done without too much care. If there is a pilot his cabin could be separated before.

But the CXV-like capsule could land on ground too - especially if it is unmanned or the pilot's cabin is separated earlier. The cargo coulkd be released as follows: short before touching the ground the ground-faced side of the capsule opens and releases the sand. Parallel to that additional parachutes are unfolded. The capsule is loosing weight because of releasing the sand and it is decelerated too in parallel - it would land on top of the sand and soft then or by significantly less speed elsewhere. The landing could be sfae perhaps. The capsule would be lighter than the manned CXV at touch-down.

The delivery of snad or similar cargo into orbit from the surface of a palnet could be done the same way as persons are carried into orbit.

Once the cargo is in space it would be no problem to launch it to another planet.

What raw materials could be delivered this way?
What else than raw materials could be transported by this method?
What do you think about this?
What else than the CXV-method could be used?

When Iinitiated this thread I focussed on space-to-ground delivery because I considered that to be the major problem.

But the interplanetary transportation intself might done alternative ways as well - it might be done without propulsion which would require a vehicle at the destination to approach and grab or catch the freight - or the freight might have propulsion.



What about it?

For landing payloads, you can just use an ablative heat shield and water landing. Although you'd want it to be guided to ensure that the mining coglomerate gets there monies worth, and doesn't have their precius platinum stolen by pirates. And that's just for landing on a planet....

We don't transport goods across the oceans unmanned, despite the fact that we have the technology. Why? It would probably be cheaper without having to provide food, fresh water, and of course wages for the crews. Unfortunately, it's equally as likely to be more expensive, due to components breaking, loss of cargo, and pirates.

You wouln't make an oil tanker unmanned.
