Q. Consider the following statements::
1.Currently, most space communication is carried out using infrared waves.
2.NASA’s Deep Space Optical Communications (DSOC) experiment seeks to use near-infrared laser signals for communication with spacecraft.
Select the correct statements using the codes given below:
Explanation-
Statement 1 is incorrect. Space communication is primarily carried out using radio waves, not infrared waves. Radio waves are a type of electromagnetic radiation with a longer wavelength than infrared waves. Radio waves can travel long distances through the vacuum of space and are not affected by Earth’s atmosphere, making them ideal for space communication.
Statement 2 is correct. NASA’s Deep Space Optical Communications (DSOC) experiment is a cutting-edge technology that has the potential to revolutionize deep space communications. By using near-infrared laser signals, DSOC can transmit data at rates that are up to 100 times faster than traditional radio frequency (RF) systems. This would allow NASA to send and receive high-resolution images and videos from spacecraft in deep space, as well as conduct real-time scientific experiments.
