Discussion Overview

The discussion revolves around predictions and reactions to the Huygens probe's landing on Titan, focusing on the nature of the surface (solid vs. liquid), potential equipment failures, and the quality of the images received. Participants explore various hypotheses about the landing site and express their thoughts on the mission's outcomes, including the quality and quantity of data returned.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants predict a solid landing surface, while others suggest the possibility of nearby liquid.
  • Concerns about equipment failure are mentioned, with some participants betting on its likelihood.
  • One participant describes a vision of Titan with lakes of methane and volcanic mountains, suggesting a dynamic environment.
  • Several participants express excitement about the data received, noting the probe's successful landing and the first images sent back.
  • Disappointment is expressed regarding the number of images returned and the failure of one of the channels.
  • There are discussions about the absence of color cameras on the probe, with some participants questioning the technological choices made for the mission.
  • Technical details about the probe's descent and data transmission are debated, including issues with frequency adjustments and the reasons behind the channel failure.
  • Some participants compare the surface images to those of Mars and Venus, expressing mixed feelings about the results.

Areas of Agreement / Disagreement

Participants express a mix of predictions regarding the landing surface, with no clear consensus on whether it is solid or liquid. There is also disagreement about the quality and quantity of images received, as well as the technological decisions made regarding camera equipment.

Contextual Notes

Participants mention various assumptions about the nature of Titan's surface and the technical capabilities of the Huygens probe, which remain unresolved. Discussions about the implications of the images and data received highlight differing expectations and interpretations.

Bets for Friday?

Solid planetfall?
Liquid planetfall?
Equipment failure?
 
Astronomy news on Phys.org
solid.
some.
 
Solid, no lakes near landing site.
 
Lakes of water emitting methane gas due to rotting vegitation. Volcanic mountains sticking out of the water with algae growth all over them. Tidal forces causing all of this. It is a moon at the right distance from Saturn for life to form. :rolleyes:

Likely solid, but still some chance of nearby liquid. Either way, it will be cool.
Please, please no equipment failure! This opportunity won't come again for a long time.
 
Equipment failure is always a good bet.
 
Goop, slush, Titanic ooze-quicksand, ... a hint of a small rise (solid?) in the distance; no liquid.
 
Solid.

Will stop transmitting successfully two minutes before the calculated moment of contact with said solid surface.
 
Huygens has landed!
First data should be received this afternoon!

I won, unfortunately :-(

Rocks, no lakes near landing site.

Cool. I just saw the first image [view from 10 miles above Titan]. Looks like the amazon river delta emptying into the Atlantic ocean.

The esa site only has 3 pictures up. There were links to about a dozen images on the other site...

check want pictures now! :-p

Is it just me or do some of the 'rocks' in that surface photo appear to be submerged in a shallow pool?
 
  • #23
Thx for link, check.

"Special" thanks for ESA... Sorry, guys, our european scientists definitely don't know how to use popular media.
 
  • #24
so uhm.. party on Titan?
 
  • #25
It seems Huygens made it all the way to the surface without failing. I am happy to be wrong in my prediction.
 
  • #26
I'm happy too. I'm a little dissapointed one of the channels failed so they only got back 350 pictures instead of the 700 or so they were expecting. Oh well... that's still awesome.
 
  • #27
actually i heard they foobared that whole thing with frequency because some engineer put wrong frequency in there and they had to adjust for it by changing the speed of descent? what was the story with that
 
  • #28
They got all the pictures back they just are not telling us.They have numerous back up channels built in just in case they lose one. Liars!
 
  • #29
Still don't understand how why they couldn't put color cameras on the probe.

Anyways, I'm a little disapointed with the results, don't know why. Surface pictures look exactly like Mars and Venus. Except for that picture it took during the decent that looked cool. Hopefully the chemical anaylsis stuff will be more interesting.

No no, the firmware on Cassini was not adjusted to deal with the Doppler shift due to the velocity difference between Huygens and Cassini. The software was, but the firmware wasn't. So the engineers got by adjusting Cassinis velocity/heading and by changing when Hugens undocked from Cassini.

But why Channel A failed is still being worked on.
