Cheers, thanks for the comments. And I'm working on ways of improving the contrast matching to improve the shadows you mention. James |

I'm certainly still very interested in seeing this through, I want to fill in that white space in my simulations. James |

However i think there is a potential problem with the GPS module as the specification says it is limited to 18000m or 60000 feet. As i understand it, this is one of several limitations enforced by the US govt (to prevent non-friendly use). I did read somewhere (sorry can't remember where) that there were several GPS solutions that didn't have this limitation. Perhaps units manufactured outside the states are better? I've also been looking into this with regard to the UMSFB project and I believe that the general limit is >18000m AND >515m/s simultaneously, i.e one can be exceeded but not both. Hence there should be no problem with balloon applications. I don't know if some GPS units differ from this or if it's just sloppiness in writing the spec sheets. Can anyone else confirm if this is true, or have regulations got me confused again? James |

This is a bit of a mess - but what with the dusty optics, the crazy style of mosaicking used to make this pan, and the shear number of individual images, it's the best I could do in my small amount of free time. Oh, and I seem to have lost access to my website (not too surprising given I left 9 months ago now) so the big versions are on a free file hosting site, I'll look into proper web hosting when I get the chance.

Wow, it looks like dragging the right front out of this mess has ended up turning it a little for the first time. |

A long time ago I read about a concept by Boeing to launch rockets (presumably small ones) off old oil-rigs. It was called Sealaunch and would take advantage of launching straight off the equator. It never got built. Anyone know what happened to the idea? Eh? It did get built, lots of launches have happened, then a big launch pad explosion occurred in January - flights resume this weekend! http://www.boeing.com/special/sea-launch/ James EDIT: Doug snuck in first. |

Yeah, that's the top row of the "West Valley View" pan taken on sols 1366 to 1369. I'm still waiting for the L2 and L5 to come down for the colour version, but here is the full pan in L7 (at half resolution and quite heavily compressed) James |

I don't see any indications of anything unusual in the tracking database. I don't know what Spirit is up to, but I'm not worried at the moment. James |

I vote that whomever has the next ISS update should start a new ISS Update Thread. We're pretty far past the landing of STS 120 at this point. Agreed, I fact I've gone one step further and moved the ISS posts that are not STS120 relevant to the dormant International Space Station (ISS) thread. |

Please note that the Minor Planet Center's official designation for Rosetta is asteroid 2007 VN84 Picked up a copy of this mornings Metro on my way back from London and got quite a shock when I turned the page and saw a big picture of Rosetta with a headline along the lines of 'We Missed Up'. I had a few moments of worry until I realized they had just picked up on this story and there hadn't been some major targeting error or something. Phew! James |
