Blaze of Glory or Grande Finale
Scientists decided to give the space orbiter, Cassini, a final shootout in a blaze of glory as it ends its paparazzi- styled swing through Saturn’s rings. Usually a space mission with a camera doesn’t have any “grande finale” and tends to phase out slowly due to a failure in the battery life or an unforeseen system break down.
In this case since its launch in 1997, Cassini has served its purpose of sending back thousands of high-quality photos and avoided crashing into any ring debris. It’s a good track record that offered scientists much more than they expected. Remember Voyager? It was doomed to a short life and it’s still talking to Earth as it rides the solar winds and leaves our Solar System!
NASA scientists held their breath each time Cassini flashed through a spin around the rings of Saturn. This time — going for the “Grand finale”– as its being called, the spacecraft will purposely dive through the debris rings of Saturn to capture as many photos before hurtling to the planet’s surface.
Retrograding 22 Times
It’s flight path includes 22 swings in and out of the rings as it retrogrades down to the planet. As long as it keeps flashing photos, it will afford a better view of the ring debris as well as the closest view of an alien surface of Saturn. No probe has really done this before.
The Jet Propulsion Laboratory (JPL) used the Deep Space Network at Goldstone CA, (one of a group of satellite dishes communicating with distant objects in space) to pick up Cassini’s far-off signal. As it dove through the gap, Cassini came within 3,000 km of Saturn’s cloud tops and within about 300 km of the innermost visible edge of the rings.
“No spacecraft has ever been this close to Saturn before,” said Jim Green, director of the Planetary Science Division at NASA.
Blazing a Trail
“In the grandest tradition of exploration, NASA’s Cassini spacecraft has once again blazed a trail, showing us new wonders and demonstrating where our curiosity can take us if we dare,” Green added.

By May 2nd, the first of these close-ups of rock, ice chunks, and other space trash caught in the belt of spinning gases, should give us the best results yet. Watch the news.
Finale in September
While we wait and hope the camera aboard Cassini has a safe flight, I can image a handful of scientists holding their breaths as each await the September delivery of its last photo download to California’s JPL facility in Pasadena.
