Let's just say the DTM was quite low res, and leave it at that |

The server was explicitly over specified when we got it - it could handle 10x the traffic and none of you would notice. Indeed we had one hack-attack about a year or so ago that emulated hundreds of thousand of visits per hour, and nobody noticed a performance hit for 24 hrs. Plus, adding mirrors is an exceptionally complex and expensive thing to do for database driven forums. Every now and again we'll get massive temporary spikes in traffic, but we only know by looking at stats, nit wondering why the site is tuning slow. |

If the autonav technique requires periodic delays to download and clear flash memory, then maybe it is not worth it; regular blind drives might do better. It may be like the hare versus the tortoise scenario... (Sorry, I can't resist a little backseat driving!) You're basically oversimplifying the variety and combination of how driving is done. Most drives are combinations of multiple types of drive. I can't remember the last time we had to stand down for a few days because of full flash, can you? And remember, applying autonav means we can drive quite a LOT further per day, taking MONTHS off the arrival date. And lest we forget, blind drives can have their own problems. coughpurgatoryahem etc etc. |

A lot of concern has been expressed about how UMSF(.com) would be affected by its association with The Planetary Society. To be honest, I just don't think that's true. There is not just cause for such concern, and because of that we've made it abundantly clear that things will change very very little, and because of that, people have not expressed much concern at all. Infact most people have used very very positive words indeed. |

It's not Earth-Mars distance that defines MER downlink budgets. It's the quality of the UHF pass to MRO/MODY which changes from Sol to Sol (a good pass, 150Mbits. a bad pass, <50 ) The reason to downlink those recent ones was to establish, on the ground, if RHAZ would have enough things to look out to start being used for AutoNav again rather than the Maxwell-Shuffle with Navcam. |

2008 TC3 was about 4m across iirc - that might be a point of reference. |

I thought Gizmodo were better than this QUOTE Did NASA really try to hide evidence of extraterrestrial life by photoshopping a picture — and then making that picture is Astronomy Picture Of The Day, just to confuse us further? It's so crazy, it might just be true! |

Good old Amatuer DSN guys. There's a ham radio group in Germany with a dish that would rival the smaller dishes of the DSN itself. |

Looks like it - the tunable laser and sample handing components are big, cylindrical and identifiable in the images and the cad rendering. I'd say the sample inlet is on the 'bottom' in those photos. Note the handling frame the instrument's mounted on - it's got a means to pivot the instrument over. |

Take the wheels off, flip the chassis over, take the bottom off, and install from, essentially, underneath. |

We must have been talking about this for 8 or 9 months, but I'm very very glad we're finally able to make it official. Thanks to all the admins and mods for being the sage sounding board they always are. Ever since I discovered I would be working at JPL - I wanted to hand the forum over to a safe pair of hands, and there are none safer than Emily's. The combination of www.AmateurSpaceImages.com and UMSF coming under the TPS banner is just a match made in digital heaven. Thanks to Jen, Lou, Bill and most of all Emily for making it happen. The Saturday before DPS in Cambridge 2005 - I met Steve Squyres for the first time, that awesome first interview MP3. The following day, I met Emily for the first time and suggested she would make an awesome admin for UMSF. Today at DPS in 2010 - 5 years later - UMSF becomes a part of a very special society, and the opportunity to turn this bar-room brawl into a searchable usable resource finally comes to fruition. And how did I end the day? Passing Steve in the corridor at DPS ( on the only night he's there ) and was able to share the good news with him. |

It would make far more sense to use the orbital imagery to produce the best DEM possible, THEN use surface data to verify the accuracy of that DEM and thus hopefully the reliability of the technique. |
