Nasa on Monday launched spacecraft Europa Clipper from Kennedy Space Center in Florida, US, to explore the possibility of life on Jupiter‘s moon Europa. The spacecraft took off on a SpaceX Falcon Heavy rocket under clear skies.
The $5.2 billion mission aims to explore whether Europa’s subsurface ocean, which lies beneath an ice shell over 10 miles thick, could be habitable.It is Nasa’s first mission dedicated to addressing this question.
Sandra Connelly, deputy associate administrator for Nasa’s science mission directorate, said, “Scientists believe Europa has conditions—water, energy, chemistry, and stability—beneath its icy surface that could support life.”
“One of the Europa Clipper mission’s main challenges is delivering a spacecraft hardy enough to withstand the pummeling of radiation from Jupiter but also sensitive enough to gather the measurements needed to investigate Europa’s environment,” Connelly added.

Nasa’s associate administrator, Jim Free, said that the mission will not search for actual living organisms. “What we discover on Europa will have profound implications for astrobiology and how we view our place in the universe,” Free said.
Weighing around 12,500 pounds, the Europa Clipper spacecraft is equipped with nine instruments to study Europa’s ocean depth, surface compounds, and magnetic field. It is Nasa’s largest planetary mission, measuring approximately 100 feet long and 58 feet wide.
The spacecraft will use gravitational assists from flybys of Mars in February and Earth in December 2026. It is expected to enter Jupiter’s orbit in April 2030 after traveling about 1.8 billion miles over 5-1/2 years and will conduct 49 flybys of Europa over a four-year period in a highly radioactive environment.
Nasa had planned to launch Europa Clipper last week but it was delayed due to Hurricane Milton.
Europa, the fourth-largest of Jupiter’s 95 recognized moons, is believed to have twice as much water as Earth’s oceans. It joins other celestial bodies like Callisto, Ganymede, and Enceladus that are thought to harbor hidden oceans.
The mission will assess whether Europa has the essential elements to support life—water, energy, and carbon-based molecules. Its radar can detect subsurface lakes and cryovolcanoes, while other instruments will study the moon’s atmosphere and possible water vapor plumes.
Planning for this mission began in 1995, said Tom McCord, a senior scientist on the mission. Despite doubts about Europa’s volcanic activity and energy sources, the mission could pave the way for future explorations of ocean worlds.

In the next few weeks, NASA will embark on a significant mission to Europa, the fourth-largest moon of Jupiter. Named Europa Clipper, this spacecraft is designed to search for potential signs of life. While Mars is often the focal point in the quest for life beyond Earth, Europa presents a promising alternative due to its potential liquid water, which is considered essential for life as we understand it. Although delays have occurred due to Hurricane Milton, NASA’s plan to launch the mission remains intact.

Why Europa Holds Potential for Life

Mars may be the easiest target to explore for life, but Europa, along with some of Saturn’s moons, could be better candidates. Liquid water is crucial for life, and on Earth, it supports the chemical reactions that allow living organisms to exist. Scientists believe that Europa, like Saturn’s moons Titan and Enceladus, has vast subsurface oceans beneath its icy exterior. This possibility makes Europa a compelling target for the search for extraterrestrial life.

What the Europa Clipper Will Do

Equipped with nine sophisticated instruments, the Europa Clipper will closely examine the moon’s surface, searching for signs of life beneath the thick ice sheet. The spacecraft will use thermal imaging, spectrometers, and cameras to detect any unusual heat or chemical activity. One of its key objectives is to locate and study potential water plumes erupting from the surface, giving insight into the moon’s subsurface oceans.

Although it will take the spacecraft over five years to reach Jupiter’s orbit, this mission marks a crucial step in exploring Europa. While the Clipper won’t be able to confirm life itself, its findings could lead to more in-depth future missions, bringing us closer to discovering life beyond Earth.
