Hey folks, Christmas came just a little bit late this year...
http://dawnpub.igpp.ucla.edu QUOTE DAWN DATA RELEASE: LEVEL 1A DATA FROM APPROACH AND SURVEY It is a LOT of data. Just the Vesta Approach includes about 2000 FC images! Wow!!!The Dawn project has created a public website that is available to serve the cruise and Vesta data sets that have been delivered to the Planetary Data System (PDS) while the data are still under review. Data are available from all three Dawn instruments, the Framing Camera (FC), the Visual and Infrared Mapping Spectrometer (VIR), and the Gamma Ray and Neutron Detector (GRaND). The data that are currently available are raw data, in engineering units, sometimes referred to as EDRs by the PDS or as NASA level-1a data. Additional data sets will be added when they are submitted to the PDS. The Dawn website is located at: http://dawnpub.igpp.ucla.edu Users of these data should exercise caution. Invariably there will be errors or omissions in the documentation. Please report any problems... I think that the first thing I'm going to work on is that approach sequence/movie that I wish I'd had in real time. The rotation of Vesta through the image sequences makes color composition very hard, but I am sure there are people here who are up to it. I hope someone here can come up with a pretty color global shot that I can put into a comparison montage! -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Time flies. It's as if Dawn was at Vesta yesterday and yet there are only about two months until Ceres arrival. Here are two images showing Vesta's Numisa crater:
The left one is a true color RGB mosaic from HAMO images. The right one includes a single clear filter LAMO frame that has been colorized from the HAMO data. It shows a bigger amount of interesting small scale details, e.g. the small dark-rayed craters. And finally a false color mosaic from LAMO images obtained with the 918, 749 and 548 nm filters. The image has been processed to greatly exaggerate any color variations to better reveal compositional variations: The big gaps are there because during the LAMO mission phase, Dawn didn't image Dawn globally in color. Also during LAMO, only images obtained with the clear filter are full resolution images. Images obtained with color/NIR filters are 2x2 binned so the resolution here isn't as high as in the RGB colorized clear filter image at top right. The HAMO images were obtained on 2011-10-27 and 2011-10-31. The single clear filter LAMO image was obtained on 2012-03-30. The LAMO images used to make the false color mosaic were obtained on 2012-02-07 and 2012-02-19 |
