Des composants Exxelia à bord du Rover Perseverance

Après la sonde InSight qui s'est posée sur la planète rouge le 26 novembre 2018 avec à son bord nos condensateurs film, c'est à bord du robot Perseverance qu'Exxelia fait son retour sur Mars !

 

Au terme d’un voyage de sept mois, le robot Perseverance de la NASA s'est posé sur Mars, hier à 21h55 heure Française. L'objectif de sa mission consiste à rechercher des traces de vie primitive ancienne sur la Planète rouge. 

Le robot est équipé de plusieurs instruments de mesure et de prélèvement, dont SuperCam, MEDA et PIXL sur lesquels nos composants sont embarqués:

  • Transformateurs et inductances: SESI, CMC et MPCI
  • Condensateurs film PM94
  • Condensateurs tantale solide CTC21
  • Résistances Ohmcraft HVD, HVR and CN 

L'objectif principal de SuperCam est de caractériser les roches présentes sur le sol Martien. L'instrument peut effectuer des analyses à distance grâce à son laser et à ses spectomètres, sans attendre le retour des échantillons sur terre.

L'analyseur dynamique, connu sous le nom de MEDA (Mars Environmental Dynamics Analyzer), effectue des mesures météorologiques, notamment la vitesse et la direction du vent, la température et l'humidité. Il mesure également la quantité et la taille des particules de poussière dans l'atmopshère martienne. 

PIXL est un spectromètre à fluorescence X qui fournira une détection et une analyse à échelle fine des éléments chimiques dans les roches et le sol.

Larger Batches of High Q-Factor Dielectric Resonators

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.
