On Wednesday, local time, SpaceX satellite chain network, Amazon's satellite project Kuiper and other satellite companies won a contract to demonstrate space communication from NASA, with a total amount of US $278.5 million < p > at present, NASA is replacing the existing satellite network with the system built by private enterprises, and hopes to introduce more commercial activities in the fields of space communication and manned spaceflight < p > among them, Amazon's Kuiper project and SpaceX star chain network won an investment of US $70 million respectively from the contract, and other satellite companies such as INMARSAT, SES, telesat and viasat won a share of the contract < p > NASA currently communicates with on orbit spacecraft through the tracking and data relay satellite network. SpaceX's manned dragon spacecraft, which shuttles between the ground and the international space station, currently uses the same communication system < p > Eli naffah, head of NASA's communications services program, said: "our goal is to get industry to work with us to develop communications networks not only for NASA but also for other space customers, with the aim of reducing operating costs." < p > according to the contract, Amazon and SpaceX are expected to complete the development and demonstration of satellite networks by 2025, NASA said in a statement < p > Amazon's Kuiper project consists of more than 3000 satellites to provide broadband Internet services to remote areas. SpaceX's satellite chain project is a larger Satellite Internet network, with about 2000 satellites in orbit < p > analysts said that the competition is very fierce, mainly in the provision of Satellite Internet services by SpaceX, Amazon and telesat. Although this service is expensive, it may bring billions of dollars in revenue every year after full operation < p > although SpaceX's star chain project has not been completed, it already has thousands of customers. Amazon's Kuiper project is even more backward. Its goal is to launch two satellite prototypes for the first time by the end of 2022. (Chen Chen) < / P > < p >
