NASA’s Europa Clipper — the largest spacecraft NASA has ever developed for a planetary mission — is already 20 million km (13 million miles) from Earth.
An artist’s thought of NASA’s Europa Clipper reveals the spacecraft in silhouette in opposition to the ground of Jupiter’s icy moon Europa, with the magnetometer progress completely deployed at prime and the antennas for the radar instrument extending out from the picture voltaic arrays.

Europa Clipper lifted off from NASA’s Kennedy Home Coronary heart in Florida on October 14, 2024.
The spacecraft is zooming alongside at 35 km per second (22 miles per second) relative to the Photo voltaic.
Europa Clipper will journey 2.9 billion km (1.8 billion miles) to succeed in at Jupiter in 2030 and in 2031 will begin a group of 49 flybys, using a set of units to assemble data that may inform scientists if the icy moon and its inside ocean have the circumstances wished to harbor life.
For now, the info mission teams are receiving from the spacecraft is strictly engineering data, telling them how the {{hardware}} is working.
Shortly after launch, Europa Clipper deployed its enormous picture voltaic arrays, which lengthen the dimensions of a basketball courtroom.
Subsequent on the report was the magnetometer’s progress, which uncoiled from a canister mounted on the spacecraft physique, extending a full 8.5 m (28 ft).
To confirm that each one went properly with the expansion deployment, the employees relied on data from the magnetometer’s three sensors.
As quickly because the spacecraft is at Jupiter, these sensors will measure the magnetic space spherical Europa, every confirming the presence of the ocean thought of beneath the moon’s icy crust and telling scientists about its depth and salinity.
After the magnetometer, the spacecraft deployed various antennas for the radar instrument.
Now extending crosswise from the picture voltaic arrays, the 4 high-frequency antennas type what appear as if two prolonged poles, each measuring 17.6 m (57.7 ft) prolonged.
Eight rectangular very-high-frequency antennas, each 2.76 m (9 ft) prolonged, have been moreover deployed — two on the two picture voltaic arrays.
“It’s an thrilling time on the spacecraft, getting these key deployments accomplished,” said Europa Clipper problem supervisor Jordan Evans, a researcher at NASA’s Jet Propulsion Laboratory.
“Most of what the employees is specializing in now might be understanding the small, attention-grabbing points throughout the data that help them understand the habits of the spacecraft on a deeper stage. That’s really good to see.”
The remaining seven units will most likely be powered on and off through December and January so that engineers can check their effectively being.
Quite a lot of units, along with the seen imager and the gasoline and filth mass spectrometers, will protect their defending covers closed for the next three or so years to guard in opposition to potential damage from the Photo voltaic all through Europa Clipper’s time throughout the inside Picture voltaic System.
As quickly as the entire units and engineering subsystems have been checked out, mission teams will shift their focus to Mars.
On March 1, 2025, Europa Clipper will attain Mars’ orbit and begin to loop throughout the Pink Planet, using the planet’s gravity to attain tempo.
Mission navigators already have completed one trajectory correction maneuver, as deliberate, to get the spacecraft on the precise course.
At Mars, they plan to activate the spacecraft’s thermal imager to grab multicolored pictures of Mars as a test operation.
As well as they plan to collect data with the radar instrument so engineers can be sure it’s working as anticipated.
The spacecraft will perform one different gravity assist in December 2026, swooping by Earth sooner than making the remainder of the prolonged journey to the Jupiter system.
In the intervening time, the magnetometer will measure Earth’s magnetic space, calibrating the instrument.
