✅Gs-3 : Science and technology- Space communication
📍Context : Psyche Spacecraft Experiment: NASA's spacecraft successfully tested a laser signal to Earth over 16 million km.
➡️Now Use this article as a chance to understand the basics of Electromagnetic spectrum- underlined in Red- Click here
➡️Data Transmission in Space: ⚜️Current Method: Mostly via radio waves with longer wavelengths and lower frequencies. ⚜️Challenge: Radio waves are susceptible to interference and offer limited data bandwidth.
⚠️Significance : Deep Space Optical Communications (DSOC)-Uses near-infrared laser signals for higher bandwidth communication. 🅾️Advantage: At least 10 times more data transfer than current radio systems; less interference.
