It was all cheers at JPL on Monday morning, Oct. 14.
NASA’s Europa Clipper, managed out of the Pasadena campus and carrying the most sophisticated probing devices ever sent to the outer solar system, rocketed away at 9:06 a.m. Pacific Time on a quest to explore Jupiter’s tantalizing moon Europa and reveal whether its vast hidden ocean might hold the keys to life.
It will take the Clipper 5 1/2 years to reach Jupiter, where it will slip into orbit around the giant gas planet and sneak close to Europa during dozens of radiation-drenched flybys.
Scientists – some of whom who have works for 25 years working on the lead-up to Monday’s launch – are almost certain a deep, global ocean exists beneath Europa’s icy crust. And where there is water, there could be life, making the moon one of the most promising places out there to hunt for it.
“It’s a chance for us to explore not a world that might have been habitable billions of years ago, but a world that might be habitable today — right now,” said program scientist Curt Niebur.
Europa Clipper won’t look for life; it has no life detectors. Instead, the spacecraft will zero in on the ingredients necessary to sustain life, searching for organic compounds and other clues as it peers beneath the ice for suitable conditions.
“Ocean worlds like Europa are not only unique because they might be habitable, but they might be habitable today,” NASA’s Gina DiBraccio said on the eve of launch.
SpaceX started Clipper on its 1.8 million-mile (3 billion-kilometer) journey, launching the spacecraft on a Falcon Heavy rocket from Florida’s Kennedy Space Center.
The $5.2 billion mission almost got derailed by transistors.
NASA didn’t learn until spring that Clipper’s transistors might be more vulnerable to Jupiter’s intense radiation field than anticipated. Clipper will endure the equivalent of several million chest X-rays during each of the 49 Europa flybys. The space agency spent months reviewing everything before concluding in September that the mission could proceed as planned.
Hurricane Milton added to the anxiety, delaying the launch by several days.
About the size of a basketball court with its solar wings unfurled, Clipper will swing past Mars and then Earth on its way to Jupiter for gravity assists. The nearly 13,000-pound (5,700-kilogram) probe should reach the solar system’s biggest planet in 2030.
Clipper will circle Jupiter every 21 days. One of those days will bring it close to Europa, among 95 known moons at Jupiter and close to our own moon in size.
The spacecraft will skim as low as 16 miles (25 kilometers) above Europa — much closer than the few previous visitors. Onboard radar will attempt to penetrate the moon’s ice sheet, believed to be 10 miles to 15 miles or more (15 kilometers to 24 kilometers) thick. The ocean below could be 80 miles (120 kilometers) or more deep.
The spacecraft holds nine instruments, with its sensitive electronics stored in a vault with dense zinc and aluminum walls for protection against radiation. Exploration will last until 2034.
If conditions are found to be favorable for life at Europa, then that opens up the possibility of life at other ocean worlds in our solar system and beyond, according to scientists. With an underground ocean and geysers, Saturn’s moon Enceladus is another top candidate.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy.
