Farewell, Cassini

The Saturn-or­bit­ing space­craft makes its fier y, fi­nal dive.

CAPE CANAVERAL, Fla. — NASA’s Cassini space­craft dis­in­te­grated in the skies above Saturn on Fri­day in a fi­nal, fate­ful blaze of cos­mic glory, fol­low­ing a re­mark­able jour­ney of 20 years.

Con­fir­ma­tion of Cassini’s ex­pected demise came about 7:55 a.m. That’s when ra­dio sig­nals from the space­craft — its last sci­en­tific gifts to Earth — came to an abrupt halt. The ra­dio waves went flat, and the space­craft fell silent.

Cassini ac­tu­ally bur ned up like a me­teor 83 min­utes ear­lier as it dove through Saturn’s at­mos­phere, be­com­ing one with the gi­ant gas planet it set out in 1997 to ex­plore. But it took that long for the news to reach Earth a bil­lion miles away.

The only space­craft to ever or­bit Saturn, Cassini showed us the planet, its rings and moons up close in all their splen­dor. Per­haps most tan­ta­liz­ing, ocean worlds were un­veiled on the moons Ence­ladus and Ti­tan, which could pos­si­bly harbor life.

Du­ti­ful to the end, the Cassini snapped its last pho­tos Thurs­day and sam­pled Satur n’s at­mos­phere F ri­day morn­ing as it made its fi­nal plunge. It was over in a minute or two.

Pro g ram man­ager Earl Maize made the of­fi­cial pro­nounce­ment:

“This has been an in­cred­i­ble mis­sion, an in­cred­i­ble space­craft and you’re all an in­cred­i­ble team,” Maize said. “I’m go­ing to call this the end of mis­sion.”

Flight con­trollers wear­ing match­ing pur­ple shirts stood and em­braced and shook hands. Project sci­en­tist Linda Spilker also had a pur ple hand­ker­chief to wipe away tears.

“It felt so much like los­ing a friend,” she told re­porters a cou­ple of hours later.

More than 1,500 peo­ple, many of them past and pre­sent team mem­bers, had gath­ered at Cal­i­for­nia’s Jet Propul­sion Lab­o­ra­tory for what was de­scribed as both a vigil and cel­e­bra­tion. Even more con­gre­gated at nearby Cal­i­for­nia In­sti­tute of Tech­nol­ogy, which runs the lab for NASA.

The space­craft tum­bled out of con­trol while plum­met­ing at more than 76,000 mph. Project of­fi­cials in­vited ground tele­scopes to look for Cassini’s last-gasp flash, but weren’t hope­ful it would be spot­ted against the vast back­drop of the so­lar sys­tem’s sec­ond largest planet. The ra­dio link ac­tu­ally held on a half-minute longer than ex­pected.

“There are times in this world when things just line up, when ev­ery­thing is just about per­fect. A child’s laugh, a desert sun­set and this morn­ing. It just couldn’ t have been bet­ter,” said Maize. “Farewell, faith­ful ex­plorer.”
