NASA fired its space lasers to communicate with the ISS - The Verge

📌 Summary:
NASA已經測試過使用激光傳輸的4K視頻串流，這項技術可以提供月球登陸的實時覆蓋。這次成功的測試表明，該機構有可能在阿提米斯任務中提供實時覆蓋，並有助於發展能夠連接人類前往火星和更遠星球的光學通信系統。NASA通常使用無線電波在地面和太空之間傳輸數據，但表示激光通信使用紅外線光可以比無線電波傳輸數據快10到100倍。
🎯 Key Points:
- NASA已成功在太空中測試激光通信，通過將來自飛機的4K視頻串流到國際太空站（ISS）和回來。
- 這一成就表明，NASA可能能夠在阿提米斯任務中提供月球登陸的實時覆蓋，並為發展能夠連接前往火星和更遠星球的人類的光學通信系統鋪平了道路。
- NASA通常使用無線電波在地面和太空之間傳輸數據，但激光通信使用紅外線光可以比無線電波傳輸數據快10到100倍。

2023 was a big year for laser communications at #NASA! It saw the first bi-directional laser communications relay with the #ISS performed by the #LCRD mission (at over 1 Gbps), a 267 Mbps downlink from deep space (19 million miles away) by the #DSOC mission, and 200 Gbps throughput on a laser link with a LEO orbiting spacecraft by the #TBIRD mission.
