Does anyone have any information about the comms package of the Euclid. Getting that amount of data from L1 to Earth must be an interesting challenge.
For Euclid, the service module provides X and K band communications, with a K band science data rate of ~55 Mbit/s during the daily telecommanding and communications period of 4 hours.
To store the large data volume that will be accumulated during observations, Euclid will have a mass memory of at least 2.6 Tbit.
You can get more information by contacting the service module team.
Thales Alenia Space in Spain has delivered the communications module for the Euclid satellite to Thales Alenia Space’s Turin plant, where it will be integrated with the service module.
