Cassini Significant Events 03/28/2012 – 04/03/2012


The most recent spacecraft tracking and telemetry data were collected on April 4 using the Deep Space Network’s 34 meterStation 15 at Goldstone, California. Aside from the issues in work with the Ultrastable Oscillator (see the Jan. 5, 2012 Significant Events) and the Cosmic Dust Analyzer, the Cassini spacecraft is in an excellent state of health and its subsystems are operating normally. Information on the present position of the Cassini spacecraft may be found on the “Present Position” page at: http://saturn.jpl.nasa.gov/mission/presentposition/.

Telemetry data from the targeted Enceladus encounter E-17 on March 27 were transmitted 1.3 billion kilometers to Earth on Wednesday; every bit was captured successfully by the Deep Space Network. The Ion and Neutral Mass Spectrometer (INMS) was able to discern variations in CO2 density among the individual gas jets as the spacecraft dove through the Enceladus south polar plume. The Cassini Plasma Spectrometer (CAPS), which was recently powered back on, acquired excellent data in and near the plume, along with the Cosmic Dust Analyzer (CDA) and INMS. A spectacular image of the south polar plume may be seen here, along with images of the icy moons Janus, taken March 27, and Dione, taken March 28:http://saturn.jpl.nasa.gov/news/cassinifeatures/feature20120328/
