On Tuesday, local time, Amazon, an American e-commerce company, announced that the company had booked 83 rocket launches to Arianespace, ula and blue origin, It is planned to put thousands of satellites of its space Internet Project "project Kuiper" into earth orbit within five years < p > it is reported that this will enable Amazon's "Kuiper program" to launch more than 90 times in five years, enough to put most of the 3236 planned satellites into orbit. According to James Watkins, a spokesman for the Kuiper plan, Amazon did not provide specific costs for the relevant contracts, but said the company had invested billions of dollars in the three transactions. Amazon also said the deal was "the largest commercial launch vehicle purchase in history" < p > "Kuiper project" needs a large number of rocket launches to build the whole satellite network in space. Amazon plans to deploy a large number of satellites in low earth orbit to provide low latency broadband Internet services around the world. To access Amazon's space Internet system, users must purchase the "Kuiper plan" antenna to scan the sky, search for satellites and establish links. Amazon has unveiled this antenna by the end of 2020. In addition, the satellite also needs to relay the ground station signals and user antenna signals that have been connected to the existing optical fiber Internet infrastructure < p > this concept is very similar to the star chain Internet being built by SpaceX. The whole satellite chain project is composed of tens of thousands of satellites. It is also a satellite deployed in low earth orbit to provide broadband Internet services to users all over the world. However, the star chain has been ahead of the "Kuiper plan" for several years. According to SpaceX, so far, the company has put more than 2000 satellites into orbit and began to provide public testing services around the world. At present, 250000 users have access to the satellite chain network. In contrast, the Kuiper program has not launched any satellites < p > however, Amazon hopes to change this situation this year. A year ago, Amazon announced that it had purchased nine launches of atlas 5 rocket from the United States joint launch alliance in order to put a number of satellites into orbit. Last November, Kuiper plan revealed that it would launch two satellite prototypes with the RS1 experimental new rocket developed by the start-up company ABL space systems. ABL space system predicts that the first flight of RS1 rocket launching satellite prototype will be carried out in the fourth quarter of 2022, in which each RS1 rocket will carry a satellite prototype. However, it depends on whether the RS1 rocket can be ready on time. It is reported that ABL space system encountered a test accident during rocket development in January this year, delaying the set time by three months < p > according to Watkins, the agreement between the Kuiper program and the ABL space system has not changed. Once the first satellite prototypes are launched, the Kuiper program can choose to launch satellites using atlas 5 or three rockets in the newly signed agreement. Amazon's latest agreement covers Ariana 6 rocket of Ariana space company, Vulcan rocket of American joint launch alliance and new Glen rocket of blue origin. It is reported that Amazon has booked 38 launches from the United States joint launch alliance, 18 launches from Ariana space and at least 12 launches from blue origin. According to the content of the agreement, Amazon can also choose to buy another 15 launches from blue origin in the future < p > the problem is that all three rockets are under development, have not been launched, and have been delayed for several years compared with the original plan. At present, Ariana space and the United States joint launch alliance are expected to launch rockets by the end of 2022, while blue origin is expected to launch the new Glenn rocket as early as 2023 < p > among the five rockets used by Amazon to launch satellites, Atlas 5 is the only rocket that has been in normal commercial operation. However, when Ariana space, the joint launch alliance and the blue origin rocket begin to fly, their carrying capacity should be much larger than the atlas 5 rocket, so that Amazon can carry more satellites on one rocket. However, the Kuiper plan has not revealed how many satellites a rocket can carry < p > before that, Amazon needs to cooperate with ABL space system to successfully send the satellite prototype into space. Subsequently, the company plans to adjust and finalize the satellite design before batch launch. Amazon would not disclose which kind of rocket it will use for its first launch, but now it seems that the company may have more than 90 different rocket launches to choose from.
