I just wanted to share something really cool because I like to test the limits of my vision with astronomical objects. For instance I have tried for decades to try to resolve at least one moon of Jupiter with my naked eye at opposition. It just isn't possible for me, but Jupiter does go from a...

So I've been doing a lot of selenography type observations and starting to understand the moon on a pretty deep level through the eyepiece. But one question I can't seem to find is if anyone has ever calculated just how far the moon was from Earth at the time it came together from the orbital...

I'd like to get an opinion on where you would put a space station around Jupiter that allows for certain functions: Function #1: Allow a spacecraft to easily coast into Jovian SOI and dock. Function #2: Allow a spacecraft to easily return to Earth or fly on to outer planets using minimal...

So I scored this great deal when some guy moving to Florida and getting rid of extra stuff put an Orion XT8 Dob on Craigslist for $75. It included the whole beginners kit. 28mm Wide Field, 10mm, 2x Barlow, blah blah and a "solar filter" I chucked in the trash as soon as I saw it. Unfortunately...

I was reading about the asteroid belt recently and learned about the concept of the Kirkwood Gaps. These are orbits within the asteroid belt that have been swept relatively clean of asteroids due to resonances with Jupiter, which perturb the asteroids that chance across these orbits into new...

My orbiter distro is missing one important piece of the puzzle and that is vinka's stuff. A google search didn't bring his page up and all the links I have seen from the forum are dead. Any mirrors or alternatives? Also, where do I put the mscvp120.dll file? I get that error that it is...

So my old PC and Orbiter distro were just hit. Out of date, clogged with broken dependencies, both needed to be redone. So, I built an i5 based PC, slapped in a gtx 960 and rebuilt my orbiter distro from the ground up. Before a thought to my other games off steam came, that orbiter distro had to...

One in a million shot, but I was just playing AMSO and launching Apollo 11. All Good, then the LAS shot free and zoomed off into the sky. All good. Not a few seconds later, for whatever reason It did not get enough outward velocity and the tower came hurtling back towards the stack and missed by...

Has anyone ever tried some of the more extreme gravitational experiments in orbiter? Like some of these extra solar planets that zip around their stars in several days, etc? Double star systems, globular clusters. I know there is a 300 AU limit but there are numerous examples of binary trinity...

A neighbor of mine got evicted a few months back and left behind a satellite dish. I talked to the landlord and told him I was going to appropriate it for science and build a radio telescope out of it and place it on a pole in the side yard next to my building where all the sat dishes are lined...

Recently I have been playing with the CEV Orion and I decided I wanted to try a rendezvous with a near earth asteroid as planned for a future Orion mission. So after a little research I settle on 2000 SG344. It requires a mere 4.8 km/s(according to IMFD, NASA/JPL say 3.4 or so) of delta v and...

I was doing some looking into hyberbolic trasfers between planets and by luck came up with this document here. https://engineering.purdue.edu/people/james.m.longuski.1/ConferencePapersPresentations/2006GuidanceStrategyforHyperbolicRendezvous.pdf Which discusses the idea of...

Hi All! I've been using Orbiter since I discovered it's original implementation back in early 2001 and it's one of maybe a half dozen programs that has had an essentially permanent home on my hard drive for the last 10 years. I fondly have spent many, many hours and days manuvering the...
