SES-17 Milestones

Check out the key highlights below!


Thermal Vacuum test completed

APRIL - SES-17 left the TVAC chamber where it successfully completed all testing.

Thermal Vacuum test commenced

FEBRUARY - During this phase the satellite is in a vacuum and subjected to extremes of temperature such as may be encountered during its lifetime in space. The thermal vacuum chamber (TVAC) is one of the largest in Europe, but to make SES-17 fit, part of the door had to be carved out.


First solar array deployment test completed

SEPTEMBER - The solar arrays are only a couple of centimetres thick but will need to deal with extreme temperatures varying between +140°C and -200°C. Furled for launch, deploying the solar arrays after separation is a delicate operation that relies on a series of pulleys, hinges, cables and springs all working in perfect synchronisation.

Service and Payload Modules successfully integrated

MAY - This is a major milestone and is one of the last steps in assembling the complete satellite.
