El febrer de 2025 es va instal·lar un reflector de cantonada a l’Estació de Recerca del Desert de Mart (MDRS) a Utah, EUA. Formava part de la missió analògica Hypatia Mars II, que va tenir lloc del 2 al 15 de febrer.

Located at 7.8 km and 5.7 km away respectively from Sentinel-3A & B ground tracks, the MDRS offers an interesting spot to conduct additional calibration activities for Sentinel-3, and possibly, other satellite missions carrying radar sensors such as altimeters. The corner is paired with a GNSS antenna that provides the exact position of the device.

The corner reflector has been developed by isardSAT and funded by the European Space Agency - ESA, as an extension of the Sentinel-3 Land Altimetry Mission Performance Cluster Service  project. It has been installed and set up by Hypatia II crew, as part of the second mission of Hypatia Mars, a female-led organisation dedicated to advancing Martian research and outreach.
