Here’s a short video of OrbitLab:
I fixed some issues that were small, yet important to the usability of OrbitLab, and these are now available for iOS on iTunes and for Android on Google Play.
OrbitLab is a continuation of something I first released as an app for Macintosh back in 1986 – Orbital Mech. That was written in Forth, with a little 68K assembly language to make some of the calculations go faster. OrbitLab is written in Lua using Corona SDK, so it runs natively on iOS and Android. In 2014 they’ll also compile to Windows Phone 8.
I plan on adding a phone-sized version. Initially I had thought that wouldn’t fly, but I have some ideas on how to make it work. After that I will add guided missions, where you will rocket your way to retrieve a disabled satellite, dock with a space station, mine an asteroid, or land on another body like the Moon or Mars.
