Emily has a great article about the difficulties getting Hayabusa back under control. http://www.planetary.org/blog/article/00001834/ |

Actually it looks like my guess was wrong - now there is pointing data for the thumbnails it looks like 'Halfmoon' is the small crater further to the southwest (in this navcam: http://qt.exploratorium.edu/mars/opportuni...00P0705R0M1.JPG ) I had assumed it was closer than that one, as multiple pointings were taken, which didn't seem necessary for that more distant one. Still, the little one next to us does look like a small buried crater - and rover trap! |

It's quite hard to see, but I think in the middle of Mike's image, between the two large ripples, there is a small crater (more obvious in 3D) the crater is called Halfmoon and colour imaging is planned for tosol (1792). Then driving again on sol 1793.  |

My screen-shots above were made on a Mac. (fully up to date OSX) Not sure what your problem could be on your MacBook, bug with the integrated graphics maybe? (I have a iMac with dedicated graphics) |

And for those that might not have realized, the flight simulator works on Mars as well!  I've just been annoying Spirit, by buzzing her in my F16. If you don't know about it, there is a fully functioning Flight Simulator built into Google Earth as an 'easter egg' - press Ctrl + Alt + A ( Cmd + Option + A on the Mac) to enter (after you've done it once a menu item appears under Tools). Have fun. http://earth.google.com/userguide/v5/ug_flightsim.html |

QUOTE (aldo12xu @ Feb 6 2009, 04:27 PM) I'm a newbie to Google Earth......how do I turn off the place names and all those red lines (image boundaries?)? I want to see nothing but the Martian terrain. Bottom left there is a window called Layers where you can tick/untick various boxes to turn those things on/off. Turn them all off apart from Terrain (the bottom one) for the true Mars Just realized that you can have outlines of lots (all?) HiRISE, CTX, MOC, HRSC and CRISM images with links to the image page on the web, by turning on the layers.

Read a few posts back on this very thread, where we talked about this problem. It seems intermittent. That link Bjorn posted worked for me this morning but it's gone again now. |

The Elevation and Azimuth dials in the background make me think that this could be at a ground tracking station. The copper loops at the top of the device make this look a bit like a receiver/transmitter for a dish antenna. Maybe. |

Is anybody else on a Mac having problems getting the Preferences pane to come up in MMB? I click on it and nothing seems to happen - I haven't tried it for a while so I don't know what I did to break it. Fully up to date Mac OSX 10.5.6, MMB 2.0.2 |

Yes - that was a mistake (Monday!) I must have been correcting the value when you replied. 3.5 is not so worrying but still maybe a little high. That is exactly the mechanism that caused the Z error at Purgatory - driving while the rover is at a significant pitch. |

My program for decoding the quaternions is at home, dam it, just when I need to dust it off. The change in 'z' is also a little worrying; 3.5m is quite a lot for a 85m drive. A similar false reading was seen at Purgatory. Not that I'm trying to worry anyone.  |

Well that was unexpected. Yestersols drive looks like it was WSW (i.e more west than south) about 85m according to the PDT site. Can't wait to see the images to confirm this. I assumed the next drive would be due south. Where are we off to now... |

QUOTE (Nirgal @ Feb 1 2009, 11:51 AM) Do the new navcams at Exploratorium as of jan-31 already show the result after that latest 160-meter drive ?? No. There are no images from 1786 yet - and nothing on the tracking site to tell us where we are yet either. Here's hoping it was a big one. |

Nice. I wondered if we would head for that linear feature. Phil, I would have positioned Oppy about one red-dot-diameter further south from where you have it - we're just the south side of the NE-SW feature. |

Yes, looks like Oppy's off the bottom of that crop now. (85m S on 1784) |

A couple of recent mosaics... 'Mustang': sol 1798  'Martian Chronicles': sols 1801 & 1804  Both images link to the same page. |

Well you obviously didn't look very hard.  http://www.esa.int/SPECIALS/Rosetta/SEMNMYO4KKF_0.html You must have missed it on APOD the day after the flyby. http://apod.nasa.gov/apod/ap080908.html P.S. You should add the Planetary society blog to your list of daily reading. http://www.planetary.org/blog/article/00001637/ And we have a 265 entry thread about the flyby here at UMSF http://www.unmannedspaceflight.com/index.php?showtopic=5256 |

I'll have to go through my code later to remind myself. But it is basically the maximum of the Fourier Power Spectrum on ripple scale lengths (~8 - 28 pixels I think) for 1D East-West slices 32 pixels long, each value being an average of ~4 pixels North-South. iirc. |

Nothing. Just investigating oDoug's thought, and Emily's follow-up, that Spirit has a problem with sols numbered 18 x 10^n (n = whole number) |

Looks like everything went fine back at sol 180 QUOTE Sol 180 marked a grand accomplishment for Spirit. The rover has survived two times the original planned mission duration of 90 sols. On this notable sol, the rover continued with remote sensing, performing miniature thermal emission spectrometer observations on disturbed soil and rover tracks. Spirit then looked at the targets "Cookie Cutter" and "Julienned" with the panoramic camera. Because of power and timing issues, Spirit was not able to complete intended microscopic imaging, Mössbauer spectrometer, and alpha particle X-ray spectrometer measurements at this site. These operations were moved into the sol 181 plan. Total odometry after sol 180 is 3414 meters (2.1 miles). Although a hiccup meant sol 181 was wasted QUOTE Unfortunately, as Spirit began to execute the sol 181 plan, the onboard software predicted an instrument deployment device collision. This prevented further arm functions and the drive. And that drive was to get to 'engineering flats' to try and fix the lubrication problem with the front-right wheel. Now back to sol 1800 |

QUOTE (Tom Tamlyn @ Jan 28 2009, 09:38 PM) Do you mean the worst of the whole drive, or merely of this segment? Worst of the whole drive - depending on the route taken. Several kilometers of these slightly smaller ripples before heading out onto the 'parking lot' (like the terrain around Eagle/Endurance) a couple of km's before 'mini-Endurance'. Here is the whole route with a green dot for our approximate location.
A long way to go... |
