  • Visited the KSC!
    Kerbal Space Program is a VERY GOOD rocket science game, with very realistic physics. Source: about 2 years ago
  • A GOOD RETROFUTURISM VIDEOGAME??
    And of course… KERBAL SPACE PROGRAM, where you can recreate as much of the classic Space Race and beyond as you like while learning (mostly) realistic orbital physics! Source: about 2 years ago
  • What other games do you play?
    KSP, ONI, Total Annihilation (where I grew my love of automation), OpenTTD (where I learned how to trains), Portal (1&2), Witcher 3, Assassin's Creed (apparently). Source: over 2 years ago

  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: about 1 year ago
  • What are the best resources to explore space from my computer?
    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago
  • Lunar Occultation of Mars
    Celestia looks as though it would do it. Source: over 1 year ago
  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
  • Help rediscovering a certain night sky exploration program?
    Yes, that's Celestia most likely. I'm not sure it is still maintained though. Source: over 1 year ago
