On September 2, local time, the Vega carrier rocket operated by Arianespace of France carried 53 satellites from 21 customers in 13 countries from the French Guiana Space Center. The last satellite was released 104 minutes after the rocket took off. These “carpool passengers” include 7 satellites weighing 15-150 kg and 46 smaller cubic satellites, which will be deployed to the sun synchronous orbits of 515 km and 530 km respectively, and perform various tasks including earth observation, communication and technical demonstration. This is the first go around mission after the failure of Vega rocket to launch the United Arab Emirates eagle eye 1 earth observation satellite on July 10 last year. The launch is also the first single launch under the European Space Agency’s small spacecraft mission service (SSMS) program. The SSMS distributor has a modular lightweight carbon fiber structure and is designed to transport multiple light payloads ranging from 1 kg cubic satellite to 500 kg satellite into space. This means that Vega rocket can provide convenient and low-cost launch opportunities for small satellites. When the satellite is deployed, the dispenser will be out of orbit to avoid space debris. The European Space Agency (ESA) said that the “Vega” launch vehicle will maximize the number of satellites launched each time, thus reducing the launch cost of each “carpool passenger” and opening the door for small satellites to enter space cheaply and conventionally. Renato lafranconi, the development project manager of the European Space Agency Vega, said in a pre launch statement that the flight heralded a new era of single launch of small satellites, demonstrating Europe’s commitment to expanding space utilization capacity, strengthening the space industry and economic development. The Vega launch vehicle was launched for the first time in February 2012, with a height of 30 meters and a diameter of 3 meters. The Vega C launch vehicle, which is scheduled to fly for the first time in 2020, will provide an additional 700 kg of carrying capacity in a wider fairing at a cost comparable to the Vega launch vehicle, the European Space Agency said. < p > < p > Ariana aerospace company was established in March 1980, with its headquarters in France.
