Inspiring true-colour Cassini picture of the week... Mimas against the rings shadow.

Some fabulous new photos have been parked on the Cassini Gallery pages in the past week, including Iapetus and more Ring shots and more as we approach the Titan-B flyby 12/13 and Dione closest approach 12/15 on our way to the biggest event of the mission so far.
I'll be airborne for some of this on approach to the UK (explained in another thread), but will try to update again before Huygens probe release in two weeks. Choice among the uploads are these two showing Prometheus mooching material and potentially causing more wake disturbances and perturbations in the F ring, and a quicktime movie called "Tilt and Whirl".

Huygens released on time and on target... Titan here we come... landing Jan 14th.
True colour Cassini picture of the week... Saturn, Titan, and (hard to spot) Mimas. Quote:

And in news from that other groovy NASA planetary exploration mission about to celebrate a year exploring Mars when most predicted a 90-day warranty or failure... Videos and Flash features marking the year are up at the link above... the official celebration to come later this month.

Tangent: did you guys know there is a NASA TV station on DirecTV? Not always the most riveting stuff (dead air time with shots of the mission control consoles for example), but pretty cool anyway. Channel was in the 300s I think. Check it out if you have DTV.

I guess I should just stay up early Friday. I have to be at work very early to leave for a team road trip anyway. Might as well just sleep early on in the car anyway. ...into the light of a dark black night. |

If anyone wants to tune over to NASA-TV you can listen in to the pre-descent news conference for the Huygens probe, which will hit Titan's surface in the next 8 hours. I love it when NASA-TV has exciting mission-oriented programming!

Huygens has landed on Titan... Data Playback to follow.

"A Fantastic Success... We are the first visitors to the surface of Titan."
- ESA chief at this morning's Huygens (First Science Data Recieved) Briefing [that we know of] "Huygens continued to send data, received here on Earth through ground stations, after Cassini had to end scheduled high-data rate reception to turn and relay science to us." "All spacecraft housekeeping data in the stream looks normal." I may be misinterpreting this early (more coffee on the way), but I took this to mean that the batteries lasted longer than expected, and effectively that we have more data from Huygens on the surface of Titan than we had bandwidth for. Cassini was always due to have limited data take due to orbit planning, but the fact that Earth stations picked up the Huygens-to-Cassini carrier signal and our final limitation on new data is/was the shortage of "big ears" more than a billion miles away. "Last spacecraft Carrier was at 1555GMT from a station in Australia... Radio telescopes around the world are being requested to try and track longer to extend the scientific doppler work and see how long Huygens survives" - Huygens Principal Investigator Dr. Jean-Pierre Lebreton The first "Actual Science Results" briefing won't start for a few hours as they decompress the datastream and collect enough info to feed the world's media. Landing on other worlds is cool. Last edited by curiousuburb : 2005-01-14 at 14:40. |

perhaps even more impressive... of the entire scheduled high-data rate relay,
not one packet was lost from B channel (redundant A channel is not happy, yet) damn Last edited by curiousuburb : 2005-01-14 at 12:29. |

I am impressed that Huygens was still transmitting after Cassini dropped below Titan's horizon AND the fact that our ground stations were able to detect those continued signels! I don't know if that is still the case or not but hopefully details will follow at the next press briefing.
Landing on other planets / moons IS cool. I cannot wait to see what images Huygens was able to snap. Show me them methane seas, damnit! I remembered listening to NPR (maybe?) a few months ago. Someone theorized that if such seas exists on Titan, the wave action would be surreal. It would be higher than normal earth waves and move much slowly. That would be a sight to see. I wonder if the pictures will be in color? Titan's orange skies - confirmed? |

This is cool as shit, really. I'd like to see what National Geographic puts together in another month or two. Thanks again for the updates, curiousuburb. |

First images back are from the Descent Imager... they have 350 images...
showed two from more than 10km up... below the haze looking down. claiming to see drainage features... pics aren't posted yet, and aren't processed to clean noise either... should get clearer later |

According to the head admin of Huygens, decoding such image is a long task.
Nobody on earth have an idea about the appearance of the surface of Titan. |

Total size of the effective Huygens Data Set during primary relay via Cassini: 4h32m (end by Horizon)
- beyond expected battery life/'warranty' period Data decompression & replay scheduled for 8 replay sessions to ensure error free decode. Preliminary analysis suggest no packet loss on Channel B, good science, primarily atmospheric composition, charge, pressure, etc at one second inhalations on the way to the surface. Extended carrier wave detection from Earth Radio Telescopes as bonus doppler science not finalized. More info at the 1/15 ESA Briefing Last edited by curiousuburb : 2005-01-15 at 12:32. |

Did anyone else listen to the radar descent MP3 and think "OMG, it's Defender!"?

Has anyone seen the image of where the lander landed? Did you see the strange geometric features above that area? It looks like Darth Vader playing soccer!! Check this out:

Holy shit. Not much grey area here (like Mars has) when talking about what caused the terrain to be formed as it is.... ...into the light of a dark black night. |
