Initially designed for a 15-year lifetime, the EUTELSAT 5 West A satellite tv for pc has retired after a formidable 20+ years of fruitful in-orbit operation. The satellite tv for pc was efficiently re-orbited as deliberate to greater than 400km above the geostationary arc, the propulsion system depressurised and {the electrical} tools on board passivated. The ultimate operation to de-activate the remaining Radio Frequency supply (telemetry transmitter) was carried out from the Issy-les-Moulineaux Satellite tv for pc Management Centre on 13 January at 09:57 UTC (10:57 Native time).
The Finish-of-Life actions operated by mission management groups positioned the satellite tv for pc in secure circumstances with an orbit and configuration totally compliant with French House Regulation and worldwide House Site visitors Administration suggestions.
Primarily based on a Spacebus 3000B3 platform manufactured by the then Alcatel Alenia House (now Thales Alenia House), the satellite tv for pc was initially constructed on behalf of Stellat. Shortly after its launch in July 2002, the satellite tv for pc was purchased by Eutelsat and renamed Atlantic Fowl-3, working from the 5 West orbital place the place it remained for its total operational life. It was given the title EUTELSAT 5 West A in 2012 and operated in an inclined orbit for the reason that finish of 2019, which enabled an prolonged lifespan of the satellite tv for pc.
A progressive switch of companies to the brand new EUTELSAT 5 West B satellite tv for pc, in addition to different satellites of the Eutelsat fleet, was began in January 2020, guaranteeing seamless continuity of operations for patrons. The EUTELSAT 5 West A continued to function till its decommissioning, notably offering maritime connectivity.
A disruptive satellite tv for pc for the Group, EUTELSAT 5 West A enabled the transition to digital tv, notably in France within the early 2000s, when analogue tv know-how was transformed to and changed by digital broadcasting.
Eva Berneke, Eutelsat Chief Govt Officer, commented: “The spectacular prolonged lifespan of EUTELSAT 5 West A showcases the first-rate satellite tv for pc management experience of the Eutelsat groups. The satellite tv for pc offered an total service availability of 99.999%, a determine that stands as a testomony to the laborious work and dedication of all of the Eutelsat groups who’ve labored collectively all through the years on this mission.”
James Matthews, Eutelsat CSR Director, added: “The decommissioning of EUTELSAT 5 West A satellite tv for pc is an ideal instance of our dedication to the accountable use of house, a basic aspect of the Group’s CSR mission. This operation exhibits how the House Site visitors Administration experience of Eutelsat is getting used to mitigate the chance of house particles for each safety and environmental considerations, guaranteeing the long-term sustainability of house for all operators”.

Device to detect orbital particles mounted outside China’s space station
Beijing (XNA) Jan 12, 2023
A particle detector has been put in on the extravehicular platform of China’s house station to acquire key information used for the house station’s security, extravehicular actions of the astronauts, organic experiments, and the examine of house materials.
The power particle detector in Wentian lab has been transported by way of the cargo airlock cabin, assisted by a robotic arm.
The detector used a brand new materials referred to as CLYC for the primary time on this planet that may obtain high-efficient neutron detec … read more
