[ti:NASA Chooses Nokia to Build First Mobile Network on the Moon] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]Nokia says it has been chosen by the American space agency NASA [00:06.92]to build the first mobile phone network on the moon. [00:13.76]The Finnish technology company recently announced [00:18.12]that its Nokia Bell Labs division [00:22.08]will build the lunar communications system. [00:27.24]It said NASA will put the equipment on a lunar lander. [00:32.88]The spacecraft is expected to reach the moon's surface in late 2022. [00:42.28]Nokia's announcement comes as the space agency continues preparations [00:49.72]for sending astronauts to the moon by 2024. [00:55.80]NASA's Artemis program [00:58.76]aims to establish a long-term human presence on the moon [01:04.32]as a "warm-up" for future missions to the planet Mars. [01:11.16]Earlier this month, NASA announced it had awarded $370 million [01:19.20]to 14 companies to provide technology for the moon-landing program. [01:27.76]The money will support studies of cryogenic fluid management [01:33.92]and technologies related to energy storage [01:38.56]and power production on the moon's surface. [01:44.04]The space agency also signed a deal for the development [01:49.20]and testing of improved lunar landing systems. [01:54.80]And it is seeking private companies [01:57.92]to mine rocks and other resources on the moon. [02:04.08]The Nokia agreement was included [02:06.92]in NASA's latest awards to private companies. [02:11.44]The space agency said it is paying the company [02:15.88]$14.1 million to build the mobile network. [02:22.72]Nokia said its network will provide critical communications [02:28.68]for work astronauts will need to perform on the moon. [02:34.16]This will include remote control of lunar vehicles [02:39.00]and other equipment, [02:40.88]real-time navigation activities and high-quality video streaming. [02:48.76]The equipment includes a base station, [02:52.68]antennas and computer software programs. [02:58.44]All the equipment will be designed to survive difficult launches, [03:04.20]lunar landings and extreme conditions in space. [03:10.92]Nokia said the equipment is designed to configure, or set up, [03:17.36]the 4G/LTE communications network on its own. [03:24.00]Marcus Weldon is Nokia's chief technology officer. [03:30.40]Weldon said he sees the 4G/LTE system as a necessity to support [03:38.56]"a sustainable human presence on the lunar surface." [03:44.64]The company decided to use 4G [03:48.08]instead of 5G, the latest mobile technology, [03:53.12]because 4G has been available longer and proven its reliability. [04:01.32]Nokia said its long-term goal is to move the moon network [04:06.72]to 5G technology in the future. [04:10.88]I'm Bryan Lynn. 更多听力请访问51VOA.COM
