Would it be feasible to use aerobraking at Titan to facilitate a Titan orbiter? What about deployment of a long lived balloon within Titan's atmosphere, can...

Is anyone aware of ANY freeware packages to track and control satellites?

What if (for the sake of discussion) there were a follow up to the Huygens mission in the works. What, given what we've learned so far, would we want on the...

Hi I was wondering what happened to Armadillo aerospace? I haven't seen an update on their site since 6 Jan 05. Surely they are not giving up. Also, even...

If I were designing the nex Titan mission I would go for a hydrogen balloon. It would not explode on Titan. I like the idea of wind power. At the temperature...

Is it true that Huygens ceased transmission less than 2 hours after touchdown? Whilst it was a magnificent achievement to travel so far and land perfectly, it...

I have no one to ask this question of, so seems the Usenet might work ;-) Does anyone think that it might be possible to surround a vehicle with sodium ions...

Hi everybody, Some days ago I have been studying a way to get trust, but without throwing any propellant to space. Last day I saw the last Indiana Jones...

Hi, I ran some of the images from the Titan probe through a terrain generation program. The results are quite cool. The source images were a bit noisy and so I...

Has anyone here ever tried building a small liquid rocket engine? Preferably from this website: http://www.risacher.org/rocket/ I am building one from that...

The files now at http://esamultimedia.esa.int/docs/titanraw/index.htm are 176-by-768 JPGs. Where the same terrain is in five or 10 frames, it seems conceivable...

The interior of liquid rocket combustion chamber is usually cooled with the so called "curtain cooling," which is a spray of hydrocarbon fuel. The fuel...

I'm trying to think through different approaches to capturing material catapulted off the lunar surface. The most comprehensive reference design I've come...

Hi What is the difference between Delta 4 and Titan III-type launch vehicles? IL of FI

In looking at a ramjet/scramjet diagram, it seems that the burnt gas would want to go in both direction: towards both the inlet and the outlet. Since there is...

I'm new here so bear with me.. I have a question regarding NOX nitrous oxide is RP-1 soluble in it while the NOX is a liquid? or what hydrocarbon is soluble in...

Was this all burned during the Saturn orbit injection burn? I was thinking about the four slingshot manoevers that Cassini performed. In earth orbit, you...

Why not any first stage with LH2/LOX before Delta IV? Maybe this is a dump question too but I have always wondered that: How much powerful Saturn 5 would have...

Does Huygens not detach from it's chute after touchdown? It would be unfortunate if it were dragged by surface winds and so could not return any surface...

Here you can watch various nebulae stereoscopically! http://139.134.5.123/tiddler2/stereographer/gallery/nebula/nebula.htm
