\t\t\t\t\t\t28\/06\/2024<\/span> Europe\u2019s newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test important new technologies in orbit, Ariane 6\u2019s first flight will showcase the versatility and flexibility of this impressive, heavy-lift launcher. Read on for all about LIFI, then see who else is flying first.<\/p>\n<\/p><\/div>\n<\/p><\/div>\n As well as CubeSats and reentry capsules, Ariane 6 will launch four onboard experiments that will carry out research during the rocket\u2019s flight, ending their mission as the rocket does. LIFI is one of them, a new technology experiment from French company Oledcomm, a spinoff from Paris-Saclay University.<\/p>\n<\/p><\/div>\n Wi-Fi (\u2018Wireless Fidelity\u2019) uses radio waves to send data without wires, providing wireless internet and network connections. Li-Fi (\u2018Light Fidelity\u2019) does the same using light, that for certain applications may offer greater security, higher bandwidth, lower cost and power consumption compared to using Wi-Fi.<\/p>\n \u201cLEDs can switch on and off several million times a second. Using the invisible spectrum of light in the infrared, Oledcomm converts information into binary data, like optical Morse code. This modulation occurs so quickly, more than 10 million times a second, that the eye cannot perceive it. Our experiment will confirm that this technology can also be used under space conditions.”<\/p>\n For space missions, Li-Fi technology allows for ultra-secure and interference-free wireless connection, and significant weight savings by eliminating radiation-resistant space-grade cables. It is an important step forward too for intra-satellite communications \u2013 i.e. the exchange of information between different subsystems within a single satellite.\u00a0Ariane 6, during its first launch set for early July, will be the first rocket to integrate Li-Fi technology.<\/p>\n<\/p><\/div>\n The 40 x 60 x 16 mm LIFI experiment consists of two \u2018SatelLiFe\u2019 modules 80 cm apart, fitted under the rocket’s fairing, which will communicate via Li-Fi. On detection of lift-off, they will exchange data with each other, enabling the team to study the communication performance and ensure the system is robust to withstand the rigours of launch.<\/p>\n<\/p><\/div>\n The LIFI experiment could simplify the process of integrating payloads onto Ariane 6 as, in the future, Li-Fi technology could be used to communicate between rocket parts instead of cables, lessening the mass onboard and therefore the amount of fuel needed, potentially having an impact on the associated carbon footprint.<\/p>\n \u201cThe LIFI experiment onboard Ariane 6 will be a world first as it will be the first time that Li-Fi technology has been embedded in a\u00a0space\u00a0launcher, enabling us to demonstrate the robustness of Li-Fi systems and plan for future integration onto other missions, rockets, satellites and spacecraft,\u201d explains Benjamin Azoulay, CEO (Chief Executive Officer) of Oledcomm.<\/p>\n<\/p><\/div>\n \u201cThis is an incredible opportunity offered to us by ArianeGroup and ESA, whom we would like to thank. Beyond the visibility of being part of Ariane 6\u2019s first launch, which is going to be enormous, with the technical support from ArianeGroup teams we have increased our skills in various areas. We are happy to be part of the adventure and hope it will be a success.\u201d<\/p>\n Europe’s new heavy-lift rocket has been designed for all futures, and at its core is maximum versatility. Ariane 6 can put any satellite or payload into any orbital path. This is made possible with the new restartable Vinci engine that will power up the Ariane 6 upper stage repeatedly, stopping and starting to insert spacecraft into any orbit they need to be.<\/p>\n<\/p><\/div>\n \u201cOver and above the excitement and pleasure I have had in carrying out this project, it is almost a childhood dream that I am realising: working for the European launcher Ariane 6! What an opportunity,\u201d concludes Oledcomm\u2019s Maxime L\u2019huillier, responsible for developing the software for the LIFI demonstrator.\u00a0\u201cI now hope that this is just the beginning of Li-Fi communication within the Ariane 6 launcher, and that I’ll be lucky enough to experience many more launches into orbit.\u201d<\/p>\n<\/p><\/div>\n
