NASA选定四家公司开发近地空间网络NASA selects four companies to develop Near Space Network
➀ 美国宇航局（NASA）已选定四家公司开发其近地空间网络，增强航天器的通信能力。该网络支持从气候研究到月球探索的各种任务。这些公司包括Intuitive Machines、Kongsberg Satellite Services、SSC Space和Viasat。该项目价值48.2亿美元，从2025年2月开始，至2029年9月结束，并可延长至2034年9月。 ➁ 该网络包括地面站和地球同步轨道中的跟踪数据中继卫星（TDRS）系统，为长达120万英里的任务提供通信和导航服务。它支持哈勃太空望远镜和国际空间站等任务。 ➂ 地面站和TDRS卫星使航天器能够直接向地球传输数据，便于执行关键任务操作。➀ NASA has selected four companies to develop its Near Space Network, enhancing communication capabilities for spacecraft. The network supports missions ranging from climate studies to lunar exploration. The companies include Intuitive Machines, Kongsberg Satellite Services, SSC Space, and Viasat. The project is valued at $4.82 billion and spans from February 2025 to September 2029 with an option to extend until September 2034. ➁ The network includes ground stations and Tracking Data and Relay Satellite (TDRS) systems, providing communication and navigation services for missions up to 1.2 million miles. It supports missions like the Hubble Space Telescope and the International Space Station. ➂ The ground stations and TDRS satellites enable spacecraft to transmit data directly to Earth, facilitating critical mission operations.---
