Planck fuels up

Tests conducted on Planck at Europe’s Spaceport in Kourou, French Guiana, have confirmed that the satellite’s subsystems work perfectly, and that the helium dilution cooler tanks have now been filled. While the final clean-up continues, the solar array has been checked, the satellite has been integrated with its launcher adapter and fuelling has been completed.

The last of the system reference tests, the telemetry and telecommand subsystem was completed on 17 March. The tests, carried out over a period of one month, confirmed that the satellite is in perfect condition for launch.
