A new edition of Issue #4 of Astrobiology: The Story of our Search for Life in the Universe has been released to include the NASA Europa Clipper mission. NASA Astrobiology/Aaron Gronstal To celebrate the successful launch of NASA’s Europa Clipper mission, the agency’s Astrobiology program has released a new edition of Issue #4 – Missions to the Outer Solar System – of its graphic history series Astrobiology: The Story of our Search for Life in the Universe.
Issue #4 tells the story of the outer solar system, from beyond the asteroid belt to the outer reaches of the Sun’s magnetic influence. Gas giants like Jupiter and Saturn are not habitable, but many of their moons raise questions about life’s potential far, far away from the warmth of the Sun.
One such body is Jupiter’s moon Europa, which contains an ocean of liquid water beneath its icy surface. The Europa Clipper mission is designed to help scientists understand whether this ocean holds key ingredients that could support habitable environments for life as we know it. The spacecraft launched on Oct. 14 and will arrive at Jupiter in 2030.
Additional content in the fourth edition of Issue #4 also includes ESA’s (European Space Agency) Juice (Jupiter Icy Moons Explorer) mission, which will arrive in the Jovian system in 2031 and collect data on many of Jupiter’s moons, including Ganymede, Europa, Callisto, and Io, that is complementary to Europa Clipper’s investigation.
Read more about how astrobiologists study the potential for life on worlds like Europa and the exciting data that Europa Clipper will gather by visiting NASA’s Astrobiology website and downloading the new edition.
Digital wallpaper for phones, desktops, or meeting backgrounds that feature the new Europa Clipper artwork from Issue #4 are also available.

Sols 4345-4347: Contact Science is Back on the Table
NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on sol 4343 — Martian day 4,343 of the Mars Science Laboratory mission — on Oct. 24, 2024 at 15:26:28 UTC. NASA/JPL-Caltech Earth planning date: Friday, Oct. 25, 2024
The changes to the plan Wednesday, moving the drive a sol earlier, meant that we started off planning this morning about 18 meters (about 59 feet) farther along the western edge of Gediz Vallis and with all the data we needed for planning. This included the knowledge that once again one of Curiosity’s wheels was perched on a rock. Luckily, unlike on Wednesday, it was determined that it was safe to still go ahead with full contact science for this weekend. This consisted of two targets “Mount Brewer” and “Reef Lake,” two targets on the top and side of the same block.
Aside from the contact science, Curiosity has three sols to fill with remote imaging. The first two sols include “targeted science,” which means all the imaging of specific targets in our current workspace. Then, after we drive away on the second sol, we fill the final sol of the plan with “untargeted science,” where we care less about knowing exactly where the rover is ahead of time. A lot of the environmental team’s (or ENV) activities fall under this umbrella, which is why our dedicated “ENV Science Block” (about 30 minutes of environmental activities one morning every weekend) tends to fall at the end of a weekend plan.
But that’s getting ahead of myself. The weekend plan starts off with two ENV activities — a dust devil movie and a suprahorizon cloud movie. While cloud movies are almost always pointed in the same direction, our dust devil movie has to be specifically targeted. Recently we’ve been looking southeast toward a more sandy area (which you can see above), to see if we can catch dust lifting there. After those movies we hand the reins back over to the geology team (or GEO) for ChemCam observations of Reef Lake and “Poison Meadow.” Mastcam will follow this up with its own observations of Reef Lake and the AEGIS target from Wednesday’s plan. The rover gets some well-deserved rest before waking up for the contact science I talked about above, followed by a late evening Mastcam mosaic of “Fascination Turret,” a part of Gediz Vallis ridge that we’ve seen before.
We’re driving away on the second sol, but before that we have about another hour of science. ChemCam and Mastcam both have observations of “Heaven Lake” and the upper Gediz Vallis ridge, and ENV has a line-of-sight observation, to see how much dust is in the crater, and a pre-drive deck monitoring image to see if any dust moves around on the rover deck due to either driving or wind. Curiosity gets a short nap before a further drive of about 25 meters (about 82 feet).
The last sol of the weekend is a ChemCam special. AEGIS will autonomously choose a target for imaging, and then ChemCam has a passive sky observation to examine changing amounts of atmospheric gases. The weekend doesn’t end at midnight, though — we wake up in the morning for the promised morning ENV block, which we’ve filled with two cloud movies, another line-of-sight, and a tau observation to see how dusty the atmosphere is.

Europa Trek: NASA Offers a New Guided Tour of Jupiter’s Ocean Moon
NASA’s Europa Clipper mission is on its way to explore a moon of Jupiter that researchers believe may be one of the best places in the Solar System to search for life beyond Earth. While the spacecraft makes its more-than-five year journey to Europa, scientists, students, teachers, and the public can tour and explore the landforms of Europa with newly-released enhancements to NASA’s Europa Trek web portal.
One of the largest of Jupiter’s nearly 100 recognized moons, Europa is covered with a global ice cap. But beneath that crust of ice, researchers have found an ocean of liquid water, estimated to have about twice the volume of all of Earth’s oceans combined. This vast amount of liquid water is of particular interest to astrobiologists, scientists studying the origin, evolution, and distribution of life in the Universe. Though Europa’s ocean remains hidden beneath its global crust of ice, we can get important clues about its nature by studying the remarkable landforms of Europa’s icy surface.
To accompany the launch of Europa Clipper, NASA’s Solar System Treks Project released exciting new enhancements to its online Europa Trek portal on September 30, 2024. The new additions to Europa Trek allow users to interactively fly over and explore high-resolution imagery of Europa’s surface from the Voyager, Galileo, and Juno missions. Users can also take a new guided tour of Europa’s amazing landforms, with commentary developed by a collaboration between NASA’s Astrobiology Science Communication Guild and NASA’s Solar System Exploration Research Virtual Institute. The tour and its commentary introduce virtual explorers to the geology and possible biological significance of the diverse features of Europa’s surface.
“This is really fun. It’s cool how you can zoom into the high resolution data. I’ll spread the word about using this!” – Bob Pappalardo, Europa Clipper Project Scientist
The new tour and capabilities of Europa Trek were featured at the Europa Clipper public launch program at the Kennedy Space Center Visitor Center on October 6,2024, in advance of the October 14 launch of the mission. As part of the public program conducted by NASA’s Planetary Mission Program Office, the Europa Trek exhibit allowed hundreds of visitors to try their hands at flying over Europa and visualizing its exotic terrain.
NASA’s Solar System Treks is an infrastructure project within NASA’s Science Activation Team. Their online portals are used for mission planning, planetary science research, and Science, Technology, Engineering, & Mathematics (STEM) education. NASA’s Astrobiology Science Communication Guild is an international, community-based network of astrobiologists who engage in science communication with diverse audiences and learners. Watch for future collaborations between Solar System Treks and the Astrobiology Science Communication Guild at more locations across the Solar System!

A SpaceX Falcon Heavy rocket carrying NASA’s Europa Clipper spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 12:06 p.m. EDT on Monday, Oct. 14, 2024. After launch, the spacecraft plans to fly by Mars in February 2025, then back by Earth in December 2026, using the gravity of each planet to increase its momentum. With help of these “gravity assists,” Europa Clipper will achieve the velocity needed to reach Jupiter in April 2030.Credit: NASA/Kim Shiflett NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life. The spacecraft launched at 12:06 p.m. EDT Monday aboard a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida.
The largest spacecraft NASA ever built for a mission headed to another planet, Europa Clipper also is the first NASA mission dedicated to studying an ocean world beyond Earth. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) on a trajectory that will leverage the power of gravity assists, first to Mars in four months and then back to Earth for another gravity assist flyby in 2026. After it begins orbiting Jupiter in April 2030, the spacecraft will fly past Europa 49 times.
“Congratulations to our Europa Clipper team for beginning the first journey to an ocean world beyond Earth,” said NASA Administrator Bill Nelson. “NASA leads the world in exploration and discovery, and the Europa Clipper mission is no different. By exploring the unknown, Europa Clipper will help us better understand whether there is the potential for life not just within our solar system, but among the billions of moons and planets beyond our Sun.”
Approximately five minutes after liftoff, the rocket’s second stage fired up and the payload fairing, or the rocket’s nose cone, opened to reveal Europa Clipper. About an hour after launch, the spacecraft separated from the rocket. Ground controllers received a signal soon after, and two-way communication was established at 1:13 p.m. with NASA’s Deep Space Network facility in Canberra, Australia. Mission teams celebrated as initial telemetry reports showed Europa Clipper is in good health and operating as expected.
“We could not be more excited for the incredible and unprecedented science NASA’s Europa Clipper mission will deliver in the generations to come,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Everything in NASA science is interconnected, and Europa Clipper’s scientific discoveries will build upon the legacy that our other missions exploring Jupiter — including Juno, Galileo, and Voyager — created in our search for habitable worlds beyond our home planet.”
The main goal of the mission is to determine whether Europa has conditions that could support life. Europa is about the size of our own Moon, but its interior is different. Information from NASA’s Galileo mission in the 1990s showed strong evidence that under Europa’s ice lies an enormous, salty ocean with more water than all of Earth’s oceans combined. Scientists also have found evidence that Europa may host organic compounds and energy sources under its surface.
If the mission determines Europa is habitable, it may mean there are more habitable worlds in our solar system and beyond than imagined.
“We’re ecstatic to send Europa Clipper on its way to explore a potentially habitable ocean world, thanks to our colleagues and partners who’ve worked so hard to get us to this day,” said Laurie Leshin, director, NASA’s Jet Propulsion Laboratory in Southern California. “Europa Clipper will undoubtedly deliver mind-blowing science. While always bittersweet to send something we’ve labored over for years off on its long journey, we know this remarkable team and spacecraft will expand our knowledge of our solar system and inspire future exploration.”
In 2031, the spacecraft will begin conducting its science-dedicated flybys of Europa. Coming as close as 16 miles (25 kilometers) to the surface, Europa Clipper is equipped with nine science instruments and a gravity experiment, including an ice-penetrating radar, cameras, and a thermal instrument to look for areas of warmer ice and any recent eruptions of water. As the most sophisticated suite of science instruments NASA has ever sent to Jupiter, they will work in concert to learn more about the moon’s icy shell, thin atmosphere, and deep interior.
To power those instruments in the faint sunlight that reaches Jupiter, Europa Clipper also carries the largest solar arrays NASA has ever used for an interplanetary mission. With arrays extended, the spacecraft spans 100 feet (30.5 meters) from end to end. With propellant loaded, it weighs about 13,000 pounds (5,900 kilograms).
In all, more than 4,000 people have contributed to Europa Clipper mission since it was formally approved in 2015.
“As Europa Clipper embarks on its journey, I’ll be thinking about the countless hours of dedication, innovation, and teamwork that made this moment possible,” said Jordan Evans, project manager, NASA JPL. “This launch isn’t just the next chapter in our exploration of the solar system; it’s a leap toward uncovering the mysteries of another ocean world, driven by our shared curiosity and continued search to answer the question, ‘are we alone?’”
More About Europa Clipper
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, NASA JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with NASA JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at NASA Kennedy, managed the launch service for the Europa Clipper spacecraft.
