A seven-year journey is nearly over as NASA’s Cassini spacecraft is arriving at Saturn later today. The spacecraft will fire its main engine for 96 minutes beginning at 0236 UTC (10:36 pm EDT), which will put it into orbit around Saturn. Scientific data from the spacecraft will arrive on Earth about 4 hours later, and the first photographs will be returned 6 hours after that, at 1239 UTC (8:39 am EDT). As Cassini is performing these operations, the scientific equipment will be running, gathering as much data as possible on this extremely close pass.
