Europa Clipper’s Mars Radar Test Reveals Engineering Triumphs and Deep-Space Readiness
What does it take to demonstrate a radar system is ready to look through the frozen crust of a distant moon when the ultimate test is impossible on Earth? NASA’s Europa Clipper spacecraft had the answer in March 2025 by conducting a perfect in-space test of its REASON radar system during a close flyby of Mars.
NASA's Europa clipper radar instrument proves itself at Mars
As it soared past Mars in March, NASA's Europa Clipper conducted a critical radar test that had been impossible to accomplish on Earth. Now that mission scientists have studied the full stream of data,
Mars says hello as NASA's Europa Clipper warms up radar
The Mars flyby in March was primarily to use the planet's gravitational pull to tweak the Europa Clipper's trajectory. However, boffins were able to use the proximity of the planet to calibrate the spacecraft's infrared camera and test its radar ahead of its arrival at Europa in 2030, NASA has confirmed.
Europa Clipper’s Radar Triumph: What 60GB of Mars Data Reveals About Probing Alien Oceans
In the universe of planetary exploration, some experiments are so bold that even Earth’s biggest laboratories can’t hold them literally. As NASA’s Europa Clipper flew by Mars in March 2025, it wasn’t merely taking a gravity shortcut on its billion-mile journey to Jupiter.
Europa Clipper Radar Shines in Mars Test
Europa Clipper's radar instrument received echoes of its very-high-frequency radar signals that bounced off Mars and were processed to
NASA’s New Radar Just Pulled Off Something Impossible on Earth
NASA's Europa Clipper nailed a major radar test during a Mars flyby, proving it’s ready to peer into Europa’s mysterious icy shell and search for underground oceans.
NASA's Europa Clipper radar passes key test during Mars flyby
NASA's Europa Clipper spacecraft successfully tested its ice-penetrating radar system during a close flyby of Mars earlier this year.
NASA’s Europa Clipper Just Pulled Off a Stunning Radar Test on Mars
NASA’s Europa Clipper mission recently achieved a major milestone with a successful radar test that was carried out during a flyby of Mars. This test demonstrated the impressive capabilities of the spacecraft’s REASON radar system,
Europa Clipper’s Mars Flyby Reveals the Hidden Engineering Triumphs Behind Its Ice-Penetrating Radar
A radar on a spacecraft, intended to investigate the mystery of an extraterrestrial ocean, was never completely tested in Earthly chambers because there wasn’t a chamber large enough on our planet. That’s the shocking truth behind NASA’s Europa Clipper mission,
