Anyone who grew up playing Asteroids knows that the orientation of your spacecraft can be completely different from its direction of travel.

Hmm it does seem to be about 3 degrees. There's potential for operator error of course, the source material isn't great and I didn't grab frames evenly. Unless there might have been some roll in the manouvre as well perhaps? That would possibly look like that. Where was the camera? It's obviously off centre, was it offset vertically as well? Gah, I don't have time to set up a scene in 3d and try it, not right at the moment. I really should be doing other stuff...  |

Looking at the posting history of spacewoman I came across this entry from sts60 on her 'moon rocks and laser reflectors thread': Since her last post before starting this latest thread was June 2008 that's positively spooky...  |

This is why I continue to like B5 despite the CGi aging terribly and the messiah plot being a little lot hackneyed; they got the bits of physics which they didn't explicitly change mostly correct. Same goes for early new!BSG, though I couldn't follow it after the first season. |

Actually, Space War would probably be the even more obscure, and it's actually possible (though tricky) to put your ship into an orbit in Space War.

I took a series of frames from the video. I just wanted to point out what truly excellent work this is. |

Anyone who grew up playing Asteroids knows that the orientation of your spacecraft can be completely different from its direction of travel. Never mind a computer game from decades ago... I experience this every time I go shopping with Alexander (please note, currently aged two and a bit). As I push the shopping trolley down the aisle, he loves it when I give the trolley a sideways twist so that it completes a 360 degree yaw even as it continues down the aisle. When I do it right, the trolley's handlebar comes straight back into my hands as I walk behind it. |

I did this with all three of my kids, to their great delight, and the occasional annoyance of supermarket staff. |

Apollo 9 is the only Apollo mission in which two manned spacecraft – the CSM and the LM – where in Earth orbit at the same time. And the Apollo-Soyuz Test Project, if you consider that an Apollo mission. |

Furthermore, there is no record of a orbit plane change for Apollo 8 -- the only lunar orbit SPS burns where LOI, orbit circularization, and TEI. CSM plane changes were performed on the later landing missions to account for the moon's rotation carrying the landed LM out of the original orbital plane. The moon's asymmetric gravity field probably also perturbed the CSM's original orbital plane. There being no LM and no landing on Apollo 8, there was no need to make a plane change while in lunar orbit. There was quite probably a small out-of-plane component to the TEI burn so that the earth at arrival would be in the resulting orbital plane. |
