Europa Clipper blasts off to study whether Jupiter’s icy moon could host life

NASA has launched another deep space mission — this one to explore an icy moon of Jupiter and study whether it could potentially be habitable. The Europa Clipper mission launched using a SpaceX Falcon Heavy at 12:06 p.m. ET today, Monday October 14, from Launch Complex 39A at Kennedy Space Center in Florida, setting off on its long journey to the Jovian system.
“Liftoff, @EuropaClipper!” NASA Administrator Bill Nelson wrote on X. “Today, we embark on a new journey across the solar system in search of the ingredients for life within Jupiter’s icy moon. Our next chapter in space exploration has begun.”

The mission aims to explore the moon of Europa, which is particularly interesting to astrobiology researchers as it has a liquid water ocean. This ocean isn’t on the moon’s surface, however — as it is so far from the sun, the ocean is hidden beneath a icy shell of around 10 to 15 miles in thickness. Missions like Galileo have orbited Europa and taken readings from it, but this effort ended in 2003. Since then, the moon has only been explored in flybys. Now, the moon will get its own dedicated mission, set to begin when Clipper arrives there in 2030.

Europa Clipper will study the moon’s ice shell to determine exactly how thick it is, and will also look beneath this shell into the ocean below to see whether it hosts materials called organic compounds — the building blocks of life. While the mission is not expecting to find evidence of life there, scientists want to know it the required elements for life to form are present, as that will help them learn about what locations in our solar system and beyond could potentially host life.
“It’s important to us to paint a picture of what that alien ocean is like — the kind of chemistry or even biochemistry that could be happening there,” said Morgan Cable of NASA’s Jet Propulsion Laboratory in a statement.
Other icy moons like Enceladus are known to give off epic plumes of water vapor from their surface, in which material from the oceans below bursts through the ice and is thrown up into the air above the moon. It’s not known if Europa also has these plumes, but to study this alien environment from orbit, Clipper will fly close to the surface and take tiny samples of material being ejected.
“The spacecraft will study gas and grains coming off Europa by sticking out its tongue and tasting those grains, breathing in those gases,” said Cable.
For now, the mission has made contact with ground control and is safely on its way to Jupiter on a 1.8-billion mile journey. It will use the gravity of other planets to give it a boost on its way, making flybys of Mars and Earth before performing a slingshot maneuver onward to its destination.

Send your name to space as part of Europa Clipper mission
Traveling to space may be the stuff of dreams for most folks, but sending your name instead is a distinct possibility.
It’s not quite the same as donning a spacesuit and being blasted to orbit, though it could be a fun way to associate yourself with an upcoming and highly ambitious mission heading toward Jupiter next year.

4 of Uranus’s icy moons could have liquid water oceans
When it comes to exploring planets in our solar system, most of the attention gets placed on those nearest to Earth which are easier to visit, and with powerful telescopes, we often observe the gas giants Jupiter and Saturn too. The more distant planets like Uranus and Neptune, however, are often overlooked and there’s growing support among planetary scientists for sending a mission there. Now, new evidence gives even more impetus for a mission to Uranus, with a recent study showing that four of the planet’s moons could host water.
Researchers from NASA’s Jet Propulsion Laboratory reanalyzed data from the Voyager 2 mission which passed Uranus in the 1980s to look at the five largest of its 27 moons: Ariel, Umbriel, Titania, Oberon, and Miranda. Using computer modeling of how porous the surfaces are, they found that four of these moons likely have liquid water oceans beneath icy crusts.

How to watch JUICE mission launch to Jupiter’s icy moons
[UPDATE: The original target launch date of Thursday, April 13, was called off due to poor weather conditions at the launch site. The JUICE mission is now targeting the morning of Friday, April 14. Full details below.]
