But I never implied no vertical velocity. It would be possible if you didn't launch perfectly horizontally, right? ---------- Post added at 06:22 AM ---------- Previous post was at 06:15 AM ---------- Nevermind these previous comments. I now understand my flaw. But still, she dodn't...

I didn't imply zero vertical velocity. ---------- Post added at 06:10 AM ---------- Previous post was at 06:09 AM ---------- Additionally, I don't expect them to go into detail or even list formulas, I just expect them to acknowledge that this is a very precise approximation.

It seems as if many textbooks say that the path of a thrown object is a parabola, and fail to mention it is in fact an elipse with one focus at the center of the earth. I have not yet seen a single textbook in which anything is mentioned of the fact that a parabola only very closely estimates...

Any guesses at a release date?

Awesome addon!!! Adds a lot of realism It's nice how the satellites are also included in the simulation

When you see license plates you immediately think of orbiter related TLA's to match the three letters on the license plate

I somehow got a CTV-LEO to the ISS in about 1 orbit... Wasn't planning it but worked out that way

My best is 2 meters above moon (with constant RCS adjustments)

Does anybody know how I can figure out the mass of a spacecraft in orbiter? I am trying to launch a satellite and I need its mass for the launcher.

Thanks!!!:tiphat:

Hi all, In my first orbiter installation, the modules tab appeared as check boxes (which I prefer), but when I installed another orbiter installation the modules appeared as two boxes with activation buttons beneath them. Can anyone tell me why this happens and if I can change the boxes back to...

Hi all, I have been trying to get to the moon and back with a Themis-A launcher plus a CTV-Lunar. Whenever I try to use IMFD I end up getting confused and running out of fuel. I thought of using Lunar Transfer mfd which I used in a tutorial but I am confused on how I set it up and use it. More...
