Hi all, I'm in the process of recording a real-time simulation of the entire Apollo 8 mission to sync up to the audio archives and play back during a webcast on the 50th anniversary in December. In doing a practice run with the Apollo 8 MCC scenario I found that the AGC's reported mission...

For the last few months I've been developing software to provide automatic video tracking to telescopes like mine. Initially this started off as a project to adapt my telescope to automatically track rocket launches: The program provides "closed-loop" tracking; a video camera piggybacking...

Just had to share this. For any orbitnaut with a whole load of spare cash burning a hole in their pocket, an original two man Gemini trainer is going to be available for auction: http://www.bonhams.com/auctions/23378/lot/30/?category=list&length=10&page=3 If you've got a spare $60-90 thousand...

I'm currently developing a new program for automatic object tracking with GOTO telescopes. It's designed to track fast moving objects, such as satellites and rockets, but unlike existing software it's not exclusive to telescopes which offer the ability to directly control the drive rates. I...

I needed to create a calculator to convert from Right Ascension and Declination in J2000 epoch to apparent altitude and azimuth from any given arbitrary position and time, so I created this spreadsheet. It will automatically precess the RA and Dec to the epoch of observation and also accounts...

I'm working on a spreadsheet to calculate the approximate longitude, latitude, and altitude of a given satellite (in this case, the Hubble Space Telescope) based on the two line elements. I've checked my work with Orbiter and while I'm close I'm still a bit off somewhere between "true...

Not my best image of ISS by far, but I ran into a problem at the start of tracking. My software glitched and caused the main view window to go off the screen where I couldn't see it, so I couldn't adjust the focus on the fly to compensate for mirror flop. It also limited my ability to ensure...

Shot this video of the space station earlier tonight. Unfortunately it's overexposed during the peak of the pass since it's the first time I've used this camera for ISS tracking. Also had just reinstalled all my software so I forgot to reset the setting on the tracking software to LX200...

I can't remember the name of this mod, but I remember seeing an add-on with multiple functions, one of which was to make re-entry flames visible from the first-person views. Does anyone know the title of the mod I'm talking about or have a link? Thanks!

I'm trying to come up with an educated guess as to the direction and speed that Apollo 13's missing service module panel left the spacecraft. I guess this could be said to fall under the category of "space physics," so does anyone know where I could find the exact attitude and orientation of...
