Got the info from a Radio that CNES get a 2mn contact with Philae last nigth and 40 second of data.
Please take this info with due precautions waiting for confirmation before opening a new topic. http://tempsreel.nouvelobs.com/en-direct/a...-spatiales.html -------------------- |

I calculated a very good estimate of the suns direction vector in Philaes body coordinate frame using the CIVA panorama. Problem is that I do not have the exact timestamp when the CIVA pano was taken. I do not exactly know how philae is rotated around that vector but it is fairly well constrained. The horizon is in frame and we know Philaes position (or a good candidate pos at least)
sun vector: http://www.unmannedspaceflight.com/index.p...st&p=215678 Problem is that they moved Philae after that Pano was taken... but that was a rotation around its Z axis right? so that would make no real difference in comms? Unless it also tipped over? I really would like that Civa Timestamp... |
