NASA’s Cassini booster is headed toward a Sept. 15 thrust into Saturn, following a final, apart flyby of a planet’s hulk moon Titan.

The booster finished a closest proceed to Titan currently during 12:04 p.m. PDT (3:04 p.m. EDT), during an altitude of 73,974 miles (119,049 kilometers) above a moon’s surface. The booster is scheduled to make hit with Earth on Sept. 12 during about 6:19 p.m. PDT (9:19 p.m. EDT). Images and other scholarship information taken during a confront are approaching to start streaming to Earth shortly after. Navigators will investigate a spacecraft’s arena following this downlink to endorse that Cassini is precisely on march to dive into Saturn during a designed time, plcae and altitude.

This apart confront is referred to informally as “the goodbye kiss” by goal engineers, since it provides a gravitational poke that sends a booster toward a thespian finale in Saturn’s top atmosphere. The geometry of a flyby causes Cassini to delayed down somewhat in a circuit around Saturn. This lowers a altitude of a moody over a world so that a booster goes too low into Saturn’s atmosphere to survive, since attrition with a atmosphere will means Cassini to bake up.

Cassini has finished hundreds of passes over Titan during a 13-year debate of a Saturn complement — including 127 precisely targeted encounters — some during tighten operation and some, like this one, some-more distant.

“Cassini has been in a long-term attribute with Titan, with a new event scarcely each month for some-more than a decade,” pronounced Cassini Project Manager Earl Maize during NASA’s Jet Propulsion Laboratory in Pasadena, California. “This final confront is something of a bittersweet goodbye, though as it has finished via a mission, Titan’s sobriety is once again promulgation Cassini where we need it to go.”

Cassini is finale a 13-year debate of a Saturn complement with an conscious thrust into a world to safeguard Saturn’s moons — in sold Enceladus, with a subsurface sea and signs of hydrothermal activity — sojourn primitive for destiny exploration. The spacecraft’s fatal dive is a final kick in a mission’s Grand Finale, 22 weekly dives (begun in late April) by a opening between Saturn and a rings. No booster has ever ventured so tighten to a world before.

An online toolkit of information and resources about Cassini’s Grand Finale and final thrust into Saturn is accessible at:

The Cassini booster was launched in 1997 and arrived during Saturn in 2004. During a time there, Cassini has made numerous thespian discoveries, including a tellurian sea with indications of hydrothermal activity within a icy moon Enceladus, and glass methane seas on another moon, Titan.

The Cassini-Huygens goal is a mild plan of NASA, ESA (European Space Agency) and a Italian Space Agency. NASA’s Jet Propulsion Laboratory, a multiplication of Caltech in Pasadena, manages a goal for NASA’s Science Mission Directorate, Washington. JPL designed, grown and fabricated a Cassini orbiter.
