Amateurs Beat Space Agencies To Titan Pictures

loconet writes "Nature.com is reporting that a group of enthusiastic amateurs managed to process raw images of Titan from the Huygens probe faster that any of the giant space agencies in charge of the mission. Terragen, a freeware program that converts the basic brightness data in aerial pictures into a topographical map, to generate the ground-level vista was used."

Be it through the materials used in the construction of the CCD, the filter placed in front of it, or the mirrors used to direct light. This is done to eliminate any possibility of un-intended consequences (for instance mirrors used to funnel X-rays to a CCD are often quite good at funneling high energy protons as well, which usually cause a bit of damage.) and to eliminate as much uncertainty and error in the system.

I'm sure a few academics had their careers represented by the HG project and the fact that someone stepped on their turf was probably very infuriating, but that is life.

Planning astronomical observations, for example, takes a great deal of advance planning. There's proposals to submit, targets to select, instrument parameters to specify, perhaps other data to process beforehand. This planning can take a substantial portion of a researcher's time (I speak from experience). Planning a space mission obviously entails an even greater amount of advance planning.

      So, in return for all of this hard work, the scientist who planned the observation (or mission, or whatever) normally gets access to the resulting data for a limited time. What's wrong with that? It means he is compensated for his time and effort, and can publish papers. That means he gets to keep his job, and his future proposals will be taken seriously.

Parallax due to coordinate center offsets was ignored. The distortion due to the optical systems was removed using an empirically-derived unwarping function.

I have two reasons for thinking that this might be the case : the fact that sol is much further from Saturn than from earth and the density of titans atmosphere that has cloaked it from us until this moment.

      I think that the CCD designers (I think at Uni. Arizona?) must have faced three challenges that would have been very difficult to resolve. First the unit must be very sensitive to produce images from the craft on relatively short exposures as it fell. Secondly the unit must be low power, or at least relatively low power, finally the unit had to be light.

      I suspect that the unit cost several million Euros, although I have seen no information, but a spend of that order would be justified by the cost of the lauch and trip to Titan and the penalty of device failure. I would be surprised if there was a chance of improving performance significantly for less than a ten million euro spend at the time, or they would have taken it and dumped another instrument, or canned another mission.

This is much more complex than just stiching the images together and has a lot to do with how the brain processes visual information. For example, although the colors in the images are all pretty orange, the way the brain perceives color relies in part on subtracting out the background and seeing the _relative_ color of objects in the field of view. Also, the total level of illumination has not been defined (there was some speculation that daylight on titan would be like full moonlight on Earth), and this will influence both the spatial resolution and color perception that a human (even with dark-adapted eyes) would see.
