As a first approximation, calculate the acceleration at the start & end of the burn and use the average. This will slightly over-do the braking required (better than under-estimating!), but if you iterate the estimate as you go you can adjust the thrust down as required - like the throttle-down...

Need an idea for your next interplanetary super ship? Just stumbled across this site: (needs WebGL support in browser) http://ship.shapewright.com/ Results can be saved as a VRML file (any converters around, haven't looked yet), and you can even get them 3D-printed & shipped to you...

Looking at my quad-core Q6600 2.40GHz overclocked to 2.70GHz that exactly what I see even when it's "idling" at 1.80GHz Trevor

Take out all the VROT (Velocity of Rotation) references

Divide the real figure by yours - look familiar??

I assume a horizontal lander would require multiple landing engines due to its distributed mass. This means a more complicated thrust control system (engine performance balance, etc) as well as serious thought about the possibility of an engine failure (sudden roll/pitch imbalance - do they need...

I wouldn't look for a specific launch window as such, but just go into an LEO parking orbit to start. With an orbital period of about 90 min, you'll quickly lap your geo-stationary target. Do a Hohmann transfer burn 180 degree from your target point, allowing for the transfer time between apo &...

Acceleration towards a base - in that case you may even have to switch to spherical geometry which will approach "flat" acceleration across small distances

I think the main reason you can't see ALL the way back is because at some point all the matter in the universe was in an ionized plasma state that I believe is opaque to electromagnetic radiation. You can't detect further back because the radiation couldn't get through!

If you can calculate the probability of EXACTLY 'r' results in 'n' trials (say 3 heads in 10 coin tosses), the way to calculate AT LEAST 'r' results (3 or more heads) is to start at 100% chance and count backwards prob(at least 3) = 1.0 - prob(0) - prob(1) - prob(2) Remember that the sum of...

I think your second calc is wrong - you're finding the chance of a pair of sixes in 5 rolls of 2 dice...you'll miss all the cases of a single six in 2 different rolls! Here's a nice explanation of permutations & combinations...look at the last section "Combinations with Repetition"...

No direct relationship at all I believe - one's a stage with a compiler/assembler process, the other's a data access technique. The analyzer may use pointers, but that's sort of besides the point, not a direct reliance or anything. Trevor

I think that's what he's on about ... they quote distances in kilometres and numbers in the thousands (or millions, etc), rather than use megametres and have number in the tens to hundreds only.

I assume you've included the font (bitmap) resource in your DLL build??

I've just recently recorded the "Tanks on the Moon" doco on the Russian lunar rover program here in Oz! Trev

If stage is an integer, why are you printing using a float format string? Try "anim %d" and see what happens

A wild guess Maybe bases always use the default Orbiter planet diameter, and you have to put them in a "crater" to place them at the right altitude compared to the surrounding terrain???

You can draw a six clockwise!

Assigning integer values to bool variables? Try run = TRUE, etc. instead Haven't coded in C for a while, but that looks more like C++ to me...
