Data Capture:  100%  DOY 004-011 2009

There is a higher than normal risk of data loss from October 2008 through
February 2009.  If there are problems with the passes, it may not be
possible to acquire additional DSN time.  This higher-risk period has been
occurring every winter for the past couple of years.  For more information
