Nosotros've enjoyed the benefits of having NASA'south Cassini spacecraft in orbit of Saturn for years. It'south almost like it's ever been in that location, looking downwards on i of the almost awe-inspiring sights in the solar system. It just seems like forever because Cassini has sent back so much amazing stuff. Cassini began its observation of Saturn in 2004, and now it's fourth dimension for the probe's terminal deed equally information technology runs low on fuel. Later this month, the spacecraft will begin a downwards spiral that eventually sends it into Saturn'southward burdensome temper. It'll see some astonishing things on the way, though.

Cassini was launched in October of 1997, taking almost seven years to attain Saturn. It arrived carrying the Huygens lander, which was successfully deployed on the surface of Saturn's moon Titan in 2005. It was the first, and equally far only landing to take place in the outer solar system. After deploying Huygens, Cassini connected its orbital observation of Saturn and its moons, but information technology did and so from a distance. NASA didn't desire to risk damage to the probe from Saturn's icy ring material, just they'll be much more daring in the coming months. This mission made a number of discoveries, including the presence of hydrocarbon lakes on Titan and the water plumes on Enceladus.

Mission managers at NASA's Jet Propulsion Laboratory (JPL) telephone call Cassini'southward last maneuvers the "Thousand Finale." Beginning on Apr 22nd, Cassini will expend some of its dwindling fuel to execute a shut flyby of Titan, which is pretty massive every bit far as moons go. Titan's gravity will slingshot Cassini toward Saturn where information technology will (hopefully) pass between Saturn's upper atmosphere and the innermost D-ring. That gap is just 1,200 miles (1,930 kilometers) broad, and it's non completely empty. Cassini is expected to be pelted by pocket-sized particles, which can pack a dial as the probe is rocketing past as more than than 76,000 mph (122,000 kph). NASA will orient the probe to shield the antenna from direct impacts.

Cassini volition be closer to Saturn than ever earlier during the Grand Finale, and NASA plans to use that opportunity to the fullest. The probe will use its mass spectrometer to clarify the gases in Saturn'due south upper atmosphere, sending back the almost detailed data ever on the composition of a gas giant.

This slingshot maneuver is non the end of the K Finale — Cassini is expected to complete 22 of these extremely close orbits before it's finally pulled down into Saturn's atmosphere. Cassini volition hit Saturn's atmosphere on September 15th, start its final iii-minute swoop into oblivion. NASA plans to use the terminal of Cassini's fuel to keep the antenna pointed toward Earth then it can transmit data for as long as possible.
