CometWatch – 4 August
Rosetta navigation camera (NAVCAM) image taken on 4 August 2014 at about 234 km from comet 67P/C-G.
As you can see, the comet is not centred in the full-frame image. This is a result of the rendezvous burn conducted the previous day, which adjusted Rosetta’s trajectory towards the comet. This effect is corrected for in the commands sent to the spacecraft after the new orbit has been determined.
The window size for today’s sub-image is 400 x 400 pixels and the factor for scaling up and interpolation is 2 (like yesterday).
From tomorrow the nucleus should be large enough to provide the full-frame image only!
