The Europa Clipper team prepares for Mars fly-by
As planned, Europa Clipper is set to do a very close fly-by of Mars on March 1, 2025, zipping past the red planet at a speed of 15.2 miles per second only 550 miles above its surface. The graphic to the right shows the spacecraft’s planned route to Jupiter, including an additional fly-by of Earth in 2026.
During this first fly-by the science team will test two of Europa Clipper’s instruments.
About a day prior to the closest approach, the mission will calibrate the thermal imager, resulting in a multicolored image of Mars in the months following as the data is returned and scientists process the data. And near closest approach, they’ll have the radar instrument perform a test of its operations — the first time all its components will be tested together. The radar antennas are so massive, and the wavelengths they produce so long that it wasn’t possible for engineers to test them on Earth before launch.
The spacecraft launched with transistors not properly hardened for the hostile environment around Jupiter. Engineers claimed these would “heal” themselves once in Jupiter orbit. No word on whether there has been any issue from these components since launch.
