After this date, the satellite will no longer be used to collect scientific data. The cool gas propellant, which is essential for the satellite’s rotation, has almost been used up. The collected data will continue to be processed and published in Data Release 4, which is planned for 2026. The final Data Release 5 is expected at the end of the decade.
