The Europa Clipper is being prepped for a five-year mission to Europa, one of many moons orbiting the planet Jupiter, and on a sunny Thursday morning in Pasadena, Calif., NASA and the Jet Propulsion Laboratory (JPL) invited Decrypt and different members of the media to get an up-close view.
Whereas there’s loads of cutting-edge tech being loaded onto the spacecraft, nonetheless, no AI chatbots will probably be aboard.
The Clipper mission
Launching in October, the Europa Clipper will research the Galilean moon Europa via a collection of flybys in orbit round Jupiter. The Europa Clipper’s mission is engineered to doc the Jovian moon and assess its habitability. It’s going to conduct detailed reconnaissance, research the icy floor and subsurface ocean, seek for indicators of life, and analyze the moon’s composition and geology.
The media day started on the NASA/JPL customer middle, the place we checked in with safety, issued our badges, and met with our guides.

Boarding a tour bus, we headed to the constructing the place the Europa Clipper was housed and commenced getting into “the clear room.”
Assembly the Europa Clipper
On the point of enter the Europa Clipper warehouse was an attention-grabbing expertise. First, we have been informed to stroll throughout an adhesive mat that might take away any dust or lingering particles from our sneakers.
After cleansing our sneakers, we turned over all tools we deliberate to take into the warehouse to be cleaned earlier than the gear was returned to us. Subsequent, we have been taken right into a room full of robes and protecting gear to swimsuit up.

After suiting up, the final step earlier than getting into the clear room was to take an air bathe to present us a final once-over to take away any mud or particles. As we entered the warehouse the place the Europa Clipper was housed, the very first thing I seen was how large the room was.
“We’ll want each inch of this house when the entire items to the Europa Clipper are put into place, and it’s time to maneuver the unit out,” a member of the standard assurance group informed Decrypt, pointing to the excessive ceiling.

The way it’s made
My first impression of the Europa Clipper was how delicate it seemed, however the group of engineers informed me that the orbiter is constructed to take a punch.

“We deal with it delicately, after which we take it to a shaker that simulates the launch situation and shakes the craft actually arduous,” JPL Harness Engineer Luis Aguila informed Decrypt. “That makes certain that the whole lot is safe, nothing’s going to interrupt alongside the best way, after which we check it once more after that,” he mentioned, noting that the group carried out the vibration testing earlier this yr.
Aguila additionally famous that the full weight of the Europa Clipper tops 13,000 kilos.
In accordance with Europa Clipper Challenge Supervisor Jordan Evans, the form and design are intentional and serve a number of functions.
“The form is pushed by a wide range of issues: it has to suit contained in the rocket, and the rocket solely has a five-meter diameter (roughly 16.4 ft), so the whole lot—together with the photo voltaic arrays—have to suit,” Evans informed Decrypt. “Then, as we do every flyby, totally different science devices have to look down on the floor of the moon.”
Evans defined that some devices are positioned to face the route the craft is flying as a result of they’re designed to research the moon’s ambiance. Different devices should be remoted from the spacecraft to keep away from interference. Evans emphasised that every instrument has particular necessities that should be built-in into the Europa Clipper’s design.
The design of the Europa Clipper, Evans mentioned, entails a fancy strategy of balancing these necessities to make sure that one doesn’t negatively affect one other, resulting in the ultimate design of the spacecraft.
Getting the info that Europa Clipper collects again to Earth takes a three-meter (roughly 9.84 ft) excessive acquire antenna mounted on prime of the spacecraft.

“That goes to the Deep House Community, which can also be run by the Jet Propulsion Laboratory,” Evans mentioned. “So irrespective of the place Jupiter and Europa Clipper are relative to Earth, one of many floor stations across the Earth has a direct line of sight to the spacecraft,” he mentioned, including that the craft is ready to ship the info via the big antenna again to these on the bottom.
AI and house exploration
Synthetic intelligence (AI) has performed a big function in current house exploration endeavors. In October, a bunch of scientists and astronomers from Northwestern College reported using AI to determine and classify supernovae in real-time.
Whereas synthetic intelligence is taking part in a rising function in house exploration and NASA/JPL projects, Evans mentioned Europa Clipper doesn’t use AI in any significant manner.
“It does not—you possibly can consider it extra like a typical pc,” added Tracy Drain, the Flight Techniques Engineer. “There’s software program that runs on board the place issues are absolutely programmed in to inform it what to do.”
The whole lot the spacecraft must function should be on board since accessing the cloud on Earth would imply a 52-minute delay every manner.
After visiting the Europa Clipper and going via the method of taking off the entire protecting gear, we took a shuttle bus to the von Kármán auditorium to study extra concerning the facility and the mission.
Excessive-tech historical past

Based in 1943, JPL traces its historical past again to the Thirties with the work of a bunch of California Institute of Expertise (Caltech) college students, lecturers, and fanatics dubbed the “Suicide Squad” by their friends. The Suicide Squad included American aeronautical engineer Frank Malina, Hungarian aerospace engineer Theodore von Kármán, and rocket scientist, chemist, and occultist John Whiteside “Jack” Parsons.

In December 1958, JPL was folded into the newly based NASA.
After visiting the Europa Clipper and going via the method of taking off the entire protecting gear, we took a shuttle bus to the von Kármán auditorium. The house was lined with posters and shows from NASA/JPL missions previous and current, together with Voyager, Cassini, and, after all, the Europa Clipper.

Look, do not contact
“The primary objective is to seek for an atmosphere that would assist life, not a life detection mission,” JPL Deputy Challenge Scientist Bonnie Buratti informed Decrypt. “We’re in search of an atmosphere the place life may kind and be sustained.”
Whereas the floor of Europa seems to be coated in ice, Buratti mentioned, in contrast to the ice world within the 2014 Christopher Nolan movie, “Interstellar,” it’s unclear if the moon’s floor is secure to land or stroll on.
As Buratti defined, proof suggests seen sediment deposits, probably plume deposits, forming a fragile floor. These distinct layers may conceal crevasse that could possibly be fallen into that remaining hidden.
“One of many issues that we’ll search for is exercise as a result of when you have a look at that image of Europa, it seems like there should not a variety of craters on it,” Buratti mentioned. “There was lively geology within the final not less than 50 million years, which is a blink of a watch in geologic time.”
As Buratti defined, if the Europa Clipper does uncover indicators of life on the moon, it’s not a name for concern however for extra exploration, acknowledging that touchdown on the lunar floor will not be an possibility right now.
“Proper now, NASA doesn’t plan to land on Europa,” Burrata mentioned. “But when we did discover something that was suggestive of life, once more, it is not a mission to search for that we’re in search of environments that would maintain life; I feel NASA would in all probability plan to ship [another mission] there.”
Debrief
Visiting the Jet Propulsion Laboratory was an incredible expertise, and for a life-long fan of house exploration and historical past, it was like Christmas had come early. When requested how a pupil in center faculty or highschool who’s eager about science and house may get a job at JPL, Drain mentioned the door was open to everybody.
“My favourite factor to inform children is that you do not have to be an engineer or a scientist to do this type of work,” Drain mentioned, emphasizing essential pondering as a key talent. “In case you are eager about arts, journalism, pc science, and finance, there are such a lot of methods that you may find yourself working right here doing issues which are associated to house.”
