Death in the Saturn skies
NASA’s Cassini spacecraft burns up in an amazing blaze of cosmic glory
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 burned up like a meteor 83 minutes earlier as it dived 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 splendour. Perhaps most tantalizing, ocean worlds were unveiled on the moons Enceladus and Titan, which could possibly harbour life.
Dutiful to the end, the Cassini snapped its last photos Thursday and sampled Saturn’s atmosphere Friday morning as it made its final plunge. It was over in a minute or two.
Program 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 purple 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.
“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.”
