Status: Current, Prime Mission
Mission Category: Earth Systematic Missions Program, Inter-Agency Partnerships
Launch Date: November 21, 2020
Launch Location: Vandenberg

Sentinel-6 Michael Freilich aims to continue high precision ocean altimetry measurements in the 2020–2030 time-frame using two successive, identical satellites, Sentinel-6A Michael Freilich and Sentinel-6B.

A secondary objective of Sentinel-6 Michael Freilich is to collect high resolution vertical profiles of temperature, using the GNSS Radio-Occultation sounding technique, to assess temperature changes in the troposphere and stratosphere and to support Numerical Weather Prediction.
