Idefix Rover With CFRP Sandwich Chassis Heads for Martian Moon
The Idefix rover, a lightweight robot built with carbon fiber-reinforced polymer, has launched toward the Martian moon Phobos. The mission aims to study the moon's surface and return soil samples to Earth by 2031.
Why it matters
This mission represents a significant advancement in lightweight aerospace engineering and deep-space exploration capabilities.
<p>The Idefix rover, jointly developed by the German Aerospace Center (DLR, Cologne, Germany) and French space agency CNES (Paris, France), launched on Oct. 19 aboard the Japan Aerospace Exploration Agency's (JAXA, Tokyo, Japan) Martian Moons eXploration (MMX) spacecraft. Around the turn of 2028/2029, Idefix is set to become the first lander to touch down on the Martian moon Phobos, where it will explore the surface for 100 days.</p><p>To meet the rover's mass target, DLR's Institute of Lightweight Systems in Braunschweig built a 2.96-kilogram chassis from more than 160 bonded parts, JEC Composites reports. Its sandwich panels pair carbon fiber-reinforced polymer (CFRP) skins with an aluminum honeycomb core, with carbon fiber/PEEK inserts replacing the core at fixing points to accept machined holes and threads.</p><p>The H3 launch vehicle carrying MMX lifted off at 9:41 p.m. CEST from the Tanegashima Space Center in Japan.
