during launch, it will be filled with 175 tons of liquid oxygen and liquid hydrogen propellant. Through its Vulcain 2 engine, it can provide 140 tons of thrust and rolling control in the main propulsion phase. This rolling maneuver will ensure that all parts of the load are equally exposed to the sun, which can avoid overheating in any area of the Weber telescope

followed by two boosters. They are 3 meters in diameter and 31 meters high. This week they will be placed on the launch pad and then fixed on the core level. The engineer will then carry out mechanical and electrical inspections. Each booster contains 240 tons of solid propellant, which will jointly provide 1200 tons of thrust, accounting for 90% of the thrust at launch

in the countdown to launch, Vulcain 2 engine is ignited first. A few seconds later, when it reached the rated operating level, the two boosters were ignited to achieve a thrust of about 1364 tons during liftoff

Weber will be the largest and most powerful telescope ever launched into space. As part of the international cooperation agreement, ESA is using the Ariane 5 launch vehicle to provide telescope launch services. In cooperation with its partners, ESA is responsible for developing and identifying the adaptability of Ariana 5 for Weber mission, and is responsible for the procurement of launch services by Ariana space

Weber is an international cooperation project between NASA, ESA and the Canadian Space Agency (CSA)

the Ariana 5 of ESA, manufactured by the Ariana group, has been in operation since 1996 and has completed more than 100 launches from the European Space Port in French Guiana. It is 53 meters high and 5.4 meters in diameter, with a mass of 780 tons when it takes off. Ariana 5 will directly send the James Webb Space Telescope into a highly accurate L2 injection orbit. Then Weber will continue to travel alone for four weeks and finally reach a place four times farther than the moon

these activities marked the beginning of the five week Ariana 5 launch vehicle preparation activity, which was synchronized with the Weber preparation team started three weeks ago. Soon, Weber will meet Ariana 5, and the teams will work together for the final integration of the launch
