Europa Clipper lifted off from NASA’s Kennedy Area Middle in Florida at 12:06 p.m. EDT on October 14, 2024 to start a six-year journey to Jupiter’s icy moon Europa, which the spacecraft will fly by 49 occasions, coming as shut as 25 km (16 miles) from the floor because it searches for elements of life.

Europa Clipper is the most important spacecraft NASA has ever constructed for a planetary mission.
With its large photo voltaic arrays prolonged, the probe might span a basketball court docket (30.5 m, or 100 toes, tip to tip).
“Congratulations to our Europa Clipper group for starting the primary journey to an ocean world past Earth,” stated NASA Administrator Invoice Nelson.
“NASA leads the world in exploration and discovery, and the Europa Clipper mission is not any totally different.”
“By exploring the unknown, Europa Clipper will assist us higher perceive whether or not there may be the potential for all times not simply inside our Photo voltaic System, however among the many billions of moons and planets past our Solar.”
“We couldn’t be extra excited for the unimaginable and unprecedented science NASA’s Europa Clipper mission will ship within the generations to come back,” stated Nicky Fox, affiliate administrator at Science Mission Directorate, NASA Headquarters.
“All the pieces in NASA science is interconnected, and Europa Clipper’s scientific discoveries will construct upon the legacy that our different missions exploring Jupiter — together with Juno, Galileo, and Voyager — created in our seek for liveable worlds past our residence planet.”
“We’re ecstatic to ship Europa Clipper on its technique to discover a doubtlessly liveable ocean world, due to our colleagues and companions who’ve labored so arduous to get us to today,” stated Dr. Laurie Leshin, director of NASA’s Jet Propulsion Laboratory.
“Europa Clipper will undoubtedly ship mind-blowing science. Whereas all the time bittersweet to ship one thing we’ve labored over for years off on its lengthy journey, we all know this exceptional group and spacecraft will broaden our data of our Photo voltaic System and encourage future exploration.”
“As Europa Clipper embarks on its journey, I’ll be serious about the numerous hours of dedication, innovation, and teamwork that made this second potential,” stated Europa Clipper mission supervisor Jordan Evans, additionally from NASA’s Jet Propulsion Laboratory.
“This launch isn’t simply the subsequent chapter in our exploration of the Photo voltaic System; it’s a leap towards uncovering the mysteries of one other ocean world, pushed by our shared curiosity and continued search to reply the query, Are we alone?”
The journey to Jupiter is an extended one — 2.9 billion km (1.8 billion miles) — and somewhat than taking a straight path there, Europa Clipper will loop round Mars after which Earth, gaining velocity because it swings previous.
The spacecraft will start orbiting Jupiter in April 2030, and in 2031 it can begin making these 49 science-focused flybys of Europa whereas looping across the gasoline big.
The orbit is designed to maximise the science Europa Clipper can conduct and decrease publicity to Jupiter’s notoriously intense radiation.
Mission scientists will be able to ‘see’ how thick the icy shell of Europa is and achieve a deeper understanding of the huge ocean beneath.
They’ll stock materials on the floor that may have come up from beneath, seek for the fingerprints of natural compounds that kind life’s constructing blocks, and pattern any gases ejected from the moon for proof of habitability.
They’ll analyze the outcomes, probing beneath the moon’s frozen shell for indicators of a water world able to supporting life.
“It’s vital to us to paint a picture of what that alien ocean is like — the sort of chemistry and even biochemistry that could possibly be occurring there,” stated Europa Clipper group member Dr. Morgan Cable, an astrobiologist at NASA’s Jet Propulsion Laboratory.
Central to that work is attempting to find the sorts of salts, ices, and natural materials that make up the important thing elements of a liveable world.
That’s the place an imager referred to as MISE (Mapping Imaging Spectrometer for Europa) is available in.
Working within the infrared, the spacecraft’s MISE divides mirrored gentle into varied wavelengths to determine the corresponding atoms and molecules.
The mission will even attempt to find potential scorching spots close to Europa’s floor, the place plumes might convey deep ocean materials nearer to the floor, utilizing an instrument referred to as E-THEMIS (Europa Thermal Emission Imaging System), which additionally operates within the infrared.
Capturing sharply detailed photos of Europa’s floor with each a slender and a wide-image digicam is the duty of the EIS (Europa Imaging System).
“The EIS imagers will give us extremely high-resolution photos to grasp how Europa’s floor developed and is constant to vary,” Dr. Cable stated.
NASA’s Cassini mission noticed a large plume of water vapor erupting from a number of jets close to the south pole of Saturn’s ice-covered moon Enceladus.
Europa might also emit misty plumes of water, pulled from its ocean or reservoirs in its shell.
Europa Clipper’s instrument referred to as Europa-UVS (Europa Ultraviolet Spectrograph) will seek for plumes and may examine any materials that may be venting into area.
Whether or not or not Europa has plumes, the spacecraft carries two devices to research the small quantity of gasoline and mud particles ejected from the moon’s floor by impacts with micrometeorites and high-energy particles: MASPEX (MAss SPectrometer for Planetary EXploration/Europa) and SUDA (SUrface Mud Analyzer).
These devices will seize the tiny items of fabric ejected from the floor, turning them into charged particles to disclose their composition.
“The spacecraft will examine gasoline and grains coming off Europa by protruding its tongue and tasting these grains, inhaling these gases,” Dr. Cable stated.
The mission will take a look at Europa’s exterior and inside construction in varied methods, too, as a result of each have far-reaching implications for the moon’s habitability.
To achieve insights into the ice shell’s thickness and the ocean’s existence, together with its depth and salinity, the mission will measure the moon’s induced magnetic discipline with the ECM (Europa Clipper Magnetometer) and mix that information with measurements {of electrical} currents from charged particles flowing round Europa — information supplied by PIMS (Plasma Instrument for Magnetic Sounding).
As well as, the mission scientists will search for particulars on every little thing from the presence of the ocean to the construction and topography of the ice utilizing REASON (Radar for Europa Evaluation and Sounding to Close to-surface), which can peer as much as 29 km (18 miles) into the shell — itself a doubtlessly liveable atmosphere.
Measuring the adjustments that Europa’s gravity causes in radio indicators ought to assist nail down ice thickness and ocean depth.
“Non-icy supplies on the floor might get moved into deep inside pockets of briny water inside the icy shell,” stated Europa Clipper group member Dr. Steve Vance, an astrobiologist at NASA’s Jet Propulsion Laboratory.
“Some may be giant sufficient to be thought of lakes, or no less than ponds.”
“Utilizing the info gathered to tell intensive pc modeling of Europa’s inside construction additionally might reveal the ocean’s composition and permit estimates of its temperature profile.”
“No matter circumstances are found, the findings will open a brand new chapter within the seek for life past Earth.”
“It’s virtually sure Europa Clipper will increase as many questions or greater than it solutions — an entire totally different class than those we’ve been considering of for the final 25 years.”
