Giotto’s brief encounter

That first set of raw images sure as hell doesn't look "uninterpretable" -- which would seem to show that the ESA really did make a very serious PR mistake by not displaying them live in standard monochrome format. (Of course, they also had no way of knowing that Thatcher would throw a temper tantrum.)

Does anyone know, if the image data of the 6 spacecraft observing Halley (the "Halley Armada") have been combined together, creating 3D models of the nucleus and the atmosphere, for example?
Second, would it be worth digging up the original Vega images? Is there anything new we can learn from reprocessing the original images, or there's no relevant development in image processing since '85? |

No need to dig...the PDS has them. Oops, I didn't notice them before; thanks. Phil: and how did you do the modeling? Was the atmosphere annoying? Did you just forget the parts of the images that clearly a showed gas/dust cloud/jet, and creating the model based on the rest (the quieter parts)? Or how is this sort of job exactly done? And were the Vega 2 images not detailed enough to be of additional use? Sorry for too many questions. |
