*gasp*

[Twi]

Ye gods.

[andrea]

all hail the madness gods, reborn in machine!

seriously? what is that? how well does it fly?

[forsaken1111]

Oy lord.

How the feck does that thing fly? It looks like ti would spin upside down and out of control within 3 seconds!

Wait, doesn't that count as flying? All of my rockets do that. I thought it was normal.

[LordSlowpoke]

It's actually surprisingly stable. Mostly due to the thrust pointing inward by default, and the absurd amount of winglets. Activating the RCS before leaving atmosphere is suicide, however. Or deactivating SAS. on second thought, the very little sas the command module provides can be disregarded as long as you pilot it right, but still

In other news, you guys just made me proud of my rocket building skill despite the fact I've yet to create something streamlined and not involving strut overload while going into orbit. :3

[Mageziya]

So close, but alas, redirecting the failed Munar Probe to Duna was a failure. I knew I should of tried and orbited Minmus.

Picture time!

I really need to learn what the hell Delta V and ISP are.

[Graknorke]

delta v is change in velocity.
ISP is some rocket science thing.

[Mageziya]

Huh. I always though Fission Mailure was an extreme Mission Failure.

Also, I think I'll need a bit more of an explanation to Delta V.

[Graknorke]

Also, I think I'll need a bit more of an explanation to Delta V.

It's how much you're changing your velocity by. I don't really know what else to say.

[forsaken1111]

Delta-V is, as I understand it, a measurement of the difference in velocity between your current velocity and direction and the target velocity and direction.

[Graknorke]

Delta-V is, as I understand it, a measurement of the difference in velocity between your current velocity and direction and the target velocity and direction.

Direction is already part of velocity.

[andrea]

speed is the number, velocity is the vector I think.

by the way. turns out that by actually using phase angles, I can avoid that lengthy and fuel burning 2200+ Delta-V burn. which means I could bring the test ship back to kerbin! this gives me hope. with the fuel I plan to add, it should comfortably do the trip back and forth. also, in the return trip I'll be able to use spare fuel in the lander...

now, time to finish building. and organize the real mission!

edit: by the way, I am in a circular orbit. quite far, but well within the range in which I can feasibly refuel. therefore, success.

[bombzero]

Explanation of Delta-V.

"Delta", or 'Δ' in Greek alphabet where it came from, is used in mathematics and especially physics and means "change in"
"Delta-V" with "V" being velocity essentially means "The change in velocity"

Everyone has struct overload.
It's just how well you hide it

[andrea]

since velocity is what matters in orbital mechanics ( and, well, mass of the bodies. but you can't really control that), you often are gives values of velocity change needed for whatever you want to do.

of course different ships will take more or less time and more or less fuel to achieve that change in vellocity. but if you want that new orbit, you still need the same Delta-V

edit: and really, everyone uses tons of struts. half of the parts in my launchers are struts! which may explain why they lag.
