The last adventures of the Cassini spacecraft and its Grand Final after nearly 20 years on Saturn

- The ground controllers of NASA's Jet Propulsion Laboratory (JPL) today confirmed that the Cassini spacecraft has survived its first voyage between Saturn and its rings, the closest flight to any probe that has reached the Earth's surface. planet.
Cassini was out of touch with Earth as the spacecraft passed inside Saturn's rings at 0900 GMT (Wednesday, April 26), using its high-gain antenna antenna as a shield against the icy particles that feared the Engineers who might stalk their way.
The spacecraft reconnected around 07:00 GMT, about 22 hours after completing the cruise between Saturn's D-ring and the planet's satellite clouds at a relative velocity of 124,000 kilometers per hour.
"In the grandest tradition of exploration, NASA's Cassini spacecraft has reopened a path, showing us new wonders and showing where our curiosity can lead us if we dare," said Jim Green, director of the planetary science division of The NASA.
A 70-meter antenna at NASA's Deep Space Network facility in Goldstone, Calif., Received the first Cassini signal this Thursday.
Engineers were sure that the spacecraft would make the journey through the ring gap unharmed. The trajectory led Cassini about 300 kilometers from the visible edge of the D ring, the deepest Saturn, and the images showed no sign of icy ring particles in the ship's path.
The models suggested that if any particle were present where the Cassini flew, it would be similar in size to microscopic smoke particles, according to NASA.
The closest approach of the Cassini to Saturn was to a distance of about 3,000 kilometers of the clouds of the planet.
The spacecraft is in the final months of a 20-year mission, heading for a final dive on September 15 in Saturn's atmosphere as it runs low on fuel.
Cassini will make similar flights to this between Saturn and its rings once a week until the fatal immersion in September, with the next ring pass set for May 2.
"The gap between Saturn and its rings is no longer an unexplored space, and we will return 21 times more," NASA wrote from the official Twitter account of the Cassini mission.
Cassini received a gravitational push from Saturn's largest moon Titan last Saturday, reshaping the spacecraft's path to begin to fly into the rings. Saturday's flight with Titan was the last chance of the mission to see the moon up close.
Scientists will use the last 22 orbits of Cassini to measure the mass of Saturn's rings for the first time, inspect the planet's atmosphere and derive the interior structure of Saturn by studying its gravitational field.
"One of the things we can do with rings is, for the first time, address the question of the origin and age of the rings," said Linda Spilker, a scientist at the Cassini project at JPL. "We will do this by measuring the mass of the rings very accurately."
"If the rings are much larger than we expected, maybe they are old, as old as Saturn, and they have been massive enough to survive micrometeorological bombardment and erosion and leave us with the rings we see today," he added. Linda Spilker. "Now, on the other hand, if the rings are less massive, they may be very young, perhaps forming as little as 100 million years ago. Perhaps a comet or a moon came too close, was torn by the gravity of Saturn and we have the rings we see today "

adios cassini pronto partiras de este universo cruel y despiadado, y llevan 20 años en saturno y que ha descubierto la nasa?
