On the morning of November 21 2013 at 8:10, the Delfi-n3Xt satellite was launched from a base in Yasny, Russia. For almost five years TU students and staff have been working on the Delfi-n3Xt, the second satellite to be built by a Dutch university. Delfi-n3Xt is the successor to the first Delft satellite, Delfi-C3, which was launched in April 2008. Although it was designed to last a year, this satellite is still functioning today. The Delfi satellites are only thirty-four centimetre high and ten centimetre wide, not much larger than a milk carton. Delfi-n3Xt uses a system of sensors and actuators to position itself. This enables the satellite to face its solar panels towards the sun for optimum energy generation.
