Hey all. I used to run the USA2 and USA3 mirrors but I wasn't able to keep the domain name active. I just tried downloading from mirrors 1 and 4 and couldn't get the torrents or the HTTP downloads. Can someone check if there are any working mirrors and perhaps share the torrent files here if...

Hey, so I’m looking for either a 100% free unlimited astrology API or I’m looking to create one myself in PHP. I’ve looked around and all the existing ones I’ve found have limits on the free tier. If anyone knows of a free one let me know so I don’t need to develop this. Otherwise… The main...

(in orbiter 2016) Is it possible to change the orbit of the moon? I'm just curious what it would look like if the moon orbited closer to earth... like 1/4th the distance, or even just for fun to see what it would look like if the moon had a circular orbit at say 6000km altitude... I'm guessing...

So I'm getting acclimated again to orbiter with the 2016 version. I haven't done many flights in a few years. Today I was somewhat disappointed near the end of my journey. What I've got Orbiter 2016 Hi-Res Textures Dx9 Client OrbiterSound DGIV IMFD AutoSave Module Launched the DGIV from Cape...

Hi All... I used to have a PHP script which would download TLEs from celestrak and generate an Orbiter Scenario from that data. I lost the work ages ago, but I'm once again interested in re-writing this. A long time ago I released the Orbiter to TLE utility which would extrapolate the current...

Spotting supernovae is relatively easy, but witnessing the immediate aftermath of those exploding stars? That's hard -- however, NASA has managed just that. By using the Kepler space telescope to capture the light of 500 galaxy every 30 minutes for 3 years, the agency caught the flash of a...

6 years later... looks like I didn't even miss a version... Wow.

I've had 3 fuel grains from my last batch that have been curing for about 3 weeks, and also a new nozzle design that's ready for testing. There's not much special in this video, just showing how I do the final motor assembly.

The most excellent spreadsheet ever for motors running KNO3/Sorbitol or Dextrose. http://members.aol.com/nakkarocketry/soft/SRM.zip here is a spreadsheet i did for a youtube viewer who was working on a 1" PVC Motor http://purinton.us/1inchmotor.pdf

I realize it's only the day before Memorial Day and I realize most of what is getting launched would be better classified as fireworks, but hearing some fireworks today gave me the idea to make a Fourth of July "Independence" rocket... The 5 weeks between now and then should be ample time to...

Seems as though the last design I used for my motor's Nozzles was a little poor (to say the least). I've been trying to find a quick and easy way to make a good nozzles that doesn't require cutting steel on a lathe (which I don't have)... These were made with a PVC Bushing, a washer, and...

Greetings Orbinauts! SAFETY FIRST! I recommend getting very familiar with the National Association of Rocketry's Safety Guidelines before attempting any form of rocketry! Check here for links to it all: http://www.nar.org/safety.html There are plenty of other rocketry organizations out...

A work in progress. This remote application will connect to an orbiter simulator across the network to provide External MFDs and Remote Vessel Controls. Some functionality will be slightly limited. This is an experiment in do-ability. So far, I have the Parent Window with Menu Bar and...

Anyone know of anybody having calculated, or attempted to calculate the velocity of our sun with reference to the center of the galaxy, and further, any figures on the velocity of our galaxy with reference to the center of the universe?

http://69.62.156.5/rev/orbiter2008-04-1-20-31-15-71.avi Here is a 45 minute long Hi-Def Divx Video showing yesterday's flight of the DeltaGliderIV from Kennedy Space Center to Brighton Beach in 24 hours. This will demonstrate ascent thru 100km, using Interplanetary MFD to plan the course...

Don't worry about it Pluto, you'll always be a planet to me.

Well... Ok not really. I'm just having some fun experimenting with home-made rocket fuel: aka Rocket Candy. Potassium Nitrate (KNO3) as Oxidizer and Sorbitol (Artificial Sweetner) as the fuel. 100% success rate on static firings of the first 4 motors. Motor casings are PVC. The throat is a flat...
