NASA's Laser Communication Breakthrough: Messages Sent Millions of Miles Away

NASA has successfully tested a laser-based communication method called Deep Space Optical Communications (DSOC), which sent data over 16 million kilometers. The system aims to improve data links between Earth and spacecraft exploring deep space, allowing for faster transmission of large amounts of data. The laser communication method takes up less space and uses less energy compared to traditional radio frequency systems. This successful test represents the farthest-ever demonstration of optical communications and is a significant milestone in NASA's goal of sending humans to Mars.
