Based on the ANDE de-orbit / height graph of USNA (http://www.ew.usna.edu/~bruninga/ande-ops.html)
I inserted the heights for Dec 5 and Dec 9: http://home.vianetworks.nl/users/hamoen/pa3guo/ande_predict_09dec2007.jpg
Based on the current keppler sets & NOVA calculations ANDE is today at 226 km.
From 225km to de-orbit the graph shows ~15 days, so de-orbit today + ~15 days = ~24 Dec ?
Please note this is NOT a formal estimate from Bob nor USNA, it is just my personal guesstimate based on the graphs.
Is there anyone that has taken a more scientific approach ?
