Science devices and different hardware for the spacecraft will come collectively within the mission’s remaining section earlier than a launch to Jupiter’s icy moon Europa in 2024.
When it’s absolutely assembled, NASA’s Europa Clipper can be as massive as an SUV with photo voltaic arrays lengthy sufficient to span a basketball court docket – all the higher to assist energy the spacecraft throughout its journey to Jupiter’s icy moon Europa. And nearly each element of the spacecraft may have been hand-crafted.
The meeting effort is already underway in clear rooms on the company’s Jet Propulsion Laboratory in Southern California. Now, engineering elements and science devices are starting to stream in from throughout the nation and Europe. Earlier than 12 months’s finish, a lot of the flight hardware – together with a collection of 9 science devices – is anticipated to be full.
The primary physique of the spacecraft is a huge 10-foot-tall (3-meter-tall) propulsion module, designed and constructed by Johns Hopkins Utilized Physics Laboratory (APL) in Laurel, Maryland, with assist from NASA’s Goddard Area Flight Heart in Greenbelt, Maryland, and JPL. The module, fitted with electronics, radios, cabling, and the propulsion subsystem, will ship to JPL this spring. Europa Clipper’s 10-foot-wide (3-meter-wide) high-gain antenna additionally can be arriving on the Lab quickly.

“We’re shifting into the section the place we see the items all come collectively as a flight system,” mentioned Europa Clipper Undertaking Supervisor Jan Chodas of JPL. “Will probably be very thrilling to see the hardware, the flight software program, and the devices get built-in and examined. To me, it’s the following stage of discovery. We’ll learn the way the system we designed will really carry out.”
Europa, which scientists are assured harbors an inner ocean with twice the quantity of water in Earth’s oceans mixed, might at present have circumstances appropriate for supporting life. Europa Clipper will orbit Jupiter and conduct a number of shut flybys of Europa to collect knowledge on the moon’s environment, floor, and inside. Its subtle payload will examine every part from the depth and salinity of the ocean to the thickness of the ice crust to the traits of potential plumes which may be venting subsurface water into house.

The primary science instrument to be accomplished was delivered to JPL final week by a crew at Southwest Analysis Institute in San Antonio, Texas. The ultraviolet spectrograph, referred to as Europa-UVS, will search above the floor of Europa for indicators of plumes. The instrument collects ultraviolet gentle, then separates the wavelengths of that gentle to assist decide the composition of the moon’s floor and gases within the environment.
As every instrument arrives at JPL, it will likely be built-in with the spacecraft and re-tested. Engineers must be certain the devices can talk with the flight laptop, spacecraft software program, and the ability subsystem.
As soon as all of the elements have been built-in to kind the massive flight system, Europa Clipper will transfer to JPL’s huge thermal vacuum chamber for testing that simulates the tough setting of deep house. There additionally can be intense vibration testing to make sure Europa Clipper can stand up to the jostling of launch. Then it’s off to Cape Canaveral, Florida, for an October 2024 launch.
For the leaders of this mission, seeing the engineering elements come along with the fleet of devices can be particularly shifting, figuring out how arduous their groups have pushed to work via the coronavirus pandemic.
“I don’t know the way I’ll really feel, seeing this come collectively. I believe it will likely be considerably overwhelming,” mentioned JPL’s Robert Pappalardo, the Europa Clipper challenge scientist. “It’s taking place – it’s changing into actual. It’s changing into tangible.”
On the similar time, the extent of issue kicks up a number of notches because the layers of the challenge merge.
“All the parallel paths of hardware and software program improvement will begin to be a part of collectively in a method that’s very seen to the crew,” mentioned JPL’s Jordan Evans, the deputy challenge supervisor. “Everyone’s eyes flip towards the built-in system that’s coming collectively, which is thrilling.”
Extra In regards to the Mission
Missions comparable to Europa Clipper contribute to the sphere of astrobiology, the interdisciplinary analysis on the variables and circumstances of distant worlds that might harbor life as we all know it. Whereas Europa Clipper is just not a life-detection mission, it should conduct detailed reconnaissance of Europa and examine whether or not the icy moon, with its subsurface ocean, has the potential to help life. Understanding Europa’s habitability will assist scientists higher perceive how life developed on Earth and the potential for locating life past our planet.
Managed by Caltech in Pasadena, California, JPL leads the event of the Europa Clipper mission in partnership with APL for NASA’s Science Mission Directorate in Washington. The Planetary Missions Program Workplace at NASA’s Marshall Area Flight Heart in Huntsville, Alabama, executes program administration of the Europa Clipper mission.
