LEDSAT Timeline
Relive all the major phases and milestones reached by the LEDSAT team during the satellite project. From concept to launch there is quite a long way to go.
End of 2016
Concept
The LEDSAT mission was conceived by Sapienza University of Rome and University of Michigan at the end of 2016. The first design iteration was carried out by the students of aerospace engineering. The satellite will be the second IKUNS (Italian Kenyan University Nano-Satellite) CubeSat, with the development of 1KUNS-PF as precursor flight. The project is supported by the Italian Space Agency (ASI).

June 2017
Selection for ESA Fly Your Satellite!
LEDSAT has been selected for the second edition of the ESA Education Fly Your Satellite! Programme. The project was selected after a selection workshop at ESA ESTEC, held in May 2017. The Programme offers technical support by the ESA Experts to the CubeSat development teams involved and provides a launch opportunity at the end of the development cycle.

2017-2018
Critical Design Review
The LEDSAT CDR takes place between fall 2017 and spring 2018, with co-location meetings held between the team and the ESA experts in December 2017 at ESA ESTEC (Noordwijk, The Netherlands). After the co-location meetings, the payload prototype boards are tested at the ESA ESTEC Co60 facility, resulting compliant with the radiation levels that will be experienced in-orbit.

2019
Phase D workshop
The closing of Phase C, the satellite parts procurement and build-up is closed by the Phase D1 workshop held at ESA ESEC-Galaxia in Transinne, Belgium.

November 2019
Payload environmental testing
The LEDSAT team completes the environmental qualification of the payload boards at the ESA CubeSat Support Facility in Transinne, Belgium. The LEDs are qualified for flight in LEO.

January-June 2020
Build-up and assembly
The final assembly of LEDSAT is performed before and after the first pandemic lockdown. At the end of June 2020, LEDSAT is fully integrated and ready for ambient and environmental testing.

July-October 2020
Ambient testing
LEDSAT passes all the functionality testing in Summer and Fall 2020. The testing campaign is held at Sapienza University of Rome, while support from ESA Education is received remotely.

November 2020 - May 2021
Environmental qualification and Flight Acceptance
LEDSAT successfully passes the environmental qualification, I.e. vibration and thermal vacuum testing. After a first round of testing at Sapienza, a Delta qualification is required to comply with the updated launch vibration levels and the test is performed at the CSF in Belgium.

July 2021
Satellite integration in the deployer
LEDSAT is integrated in the flight deployer in Brno, Czech Republic, on July 15 2021. This marks the end of the satellite ground handling and preparation and the last time the student team operates the satellite at ground.

July 2021
Launch preparation campaign
The students witness the integration of the flight deployer on the Vega payload adapter at the Centre Spatial Guyanais in Kourou, French Guyana. LEDSAT is ready to fly on the upcoming Vega launch.
