Also the despin would result in a loss of simulated gravity, not normally bad except that we have a large open water source which would love to turn into a large "gob" and bounce around.

Hey, pyrotex, you don't know what I used to do before I was an odd jobs man aboard the prophesy.

The first reason I was here may shed some light on my... 'doubtable' past...

Buggers and moon buggy rides! More texture added to the voyage. Awesome guys!

hope i'm not ruining some huge plot point with those little guys.

damn, now my hearts all a flutter with anticipation...

I like the little guys. Wish I had thought of them myself! I am curious about were you are taking it! There are currently 103 people on the ship (and the moon). So there are 103 stories to be told.

I might not make another long entry until Friday night. Busy busy busy.

Just read Pyro's post. I will make some time.

My first thought is to have large flywheels inboard of the main ring that can be manipulated to adjust the orientation without having to despin. If we are constantly despinning and respinning we will quickly go through our supply of propellant. Any thoughts?

My first thought is that the inside of the spokes is an ineffective place for a system to change the ring’s (and thus, the whole vehicle’s) orientation.

To change the attitude of a gyroscope – or anything something with significant angular momentum – torque must be applied in a direction perpendicular to the angular momentum vector. Applying it in a parallel direction won’t effect attitude at all.

Since gyroscopes translate torque into angular velocity (precisely according to the vector formula , a gyroscope with a lot of angular momentum like the Prophesy will require a lot of torque. Other than the simple quirk that the resulting angular velocity is exactly perpendicular to both the torque and the angular momentum, such maneuvers are easy to calculate. Since , the further whatever supplies the force is from the rings in the ship's fore-or-aft direction, the less the force, and consequently, the energy required for a maneuver.

As a rocket, producing force is among the things Prophesy is designed to do best. It’s designed mainly to apply that force parallel to the rings’ angular momenta, but I can imagine a fairly simple enhancement to its “thrust management” (shock-absorber) system that would allow the main atomic motor to provide ample attitude-changing thrust: allow it to handle slightly eccentric thrust.

Although the most straight-forward approach to this would be a mechanical joint connecting the blast-side parts of the system to be moved independently of the rest of the ship, I suspect that a better solution would be to allow the shock absorber to move along 2 axes rather than 1. This would be particularly easy if the shock absorber is electromagnetic, like the one used in the ”Dropzone” amusement park ride. The pellet-injecting/detonating system need only detonate pellets slightly off-center to effect an attitude change.

I was thinking to avoid going off the rails we should discuss some minor details in the story, it will save time later. So if you unsure what to add to the story, or unsure if its appropriate, just ask here.

One thing I wanted to ask was if I could be getting a transmission from Pyro who is on his way to the moon in an escape pod that "malfunctioned" while he was in it and BigDog was coincidently doing a diagnostic on it. That is if you didnt already have an idea for getting Pyro to the moon..

Get Pyro on the moon. Its critical for my 'investigation'
