ISEE-3 Status 26 June 2014: DSN Ranging Success

Just as our DSN window closed today we were able to get 2 way Doppler lock and ranging at 47.5 kHz offset.  DSN got the four ranging points needed from ISEE-3. This is the first time since 1999 that DSN has talked to the spacecraft. A follow up session tomorrow should get us a lot more recording time.
