Europa Clipper’s Martian Flyby: Infrared Vision Check before jupiter
BUCHAREST – may 18, 2025 – NASA’s Europa Clipper spacecraft, on its journey to Jupiter’s moon Europa, performed a flyby of Mars in early March 2025. This opportunistic manoeuvre allowed engineers to test and calibrate the Europa thermal imaging system, giving scientists a unique possibility before the primary mission even begins.The mission’s goals are now clearer, with the opportunity to study Mars in infrared.
europa Clipper’s Martian Flyby: Infrared Vision Check before jupiter
Nasa’s Europa Clipper mission, en route to Jupiter’s moon Europa, took a detour past Mars in early March 2025. This wasn’t just a scenic route; it was a crucial possibility to calibrate the spacecraft’s thermal imaging instruments.
A Martian Warm-Up
The Europa Clipper probe flew within 884 kilometers of Mars, using the planet’s gravity to adjust its trajectory and gain speed for its journey to Jupiter. During this flyby, the Europa Thermal Emission Imaging System (E-THEMIS) was put to the test.
E-THEMIS captured images every second for about 18 minutes, generating over a thousand grayscale photos. These images, transmitted back to earth starting May 5, were then colorized by scientists.
By comparing these images with those from existing Mars rovers, scientists coudl assess the instrument’s performance. The initial evaluation suggests the instrument is operating smoothly.
Infrared Insights
The infrared images reveal temperature variations across the Martian surface. warmer areas register around 0°C,while the colder Arctic region plunges to approximately -125°C.
Europa awaits
The primary goal of the Europa Clipper mission is to investigate Europa, one of Jupiter’s four largest moons, discovered by Galileo in the 17th century. Europa’s icy surface, crisscrossed with cracks, hints at a subsurface ocean warmed by Jupiter’s tidal forces.
Scientists speculate that this ocean could potentially harbor life. The Europa clipper, scheduled to arrive in the Jupiter system in 2030, will conduct a global scan of Europa using its thermal imager to map surface temperature distribution.
This temperature map could reveal areas where seawater is closer to the surface, potentially indicating thermal convection and the filling of cracks with warmer water.
Radar Testing
In addition to the thermal imaging tests, the Mars flyby provided an opportunity to test the Europa Clipper’s radar instruments for the first time. The data collected will be analyzed over the coming weeks and months.
