Question

Q. With reference to the Laser Communications Relay Demonstration (LCRD) sometimes seen in the news, consider the following statements: (D)

Which of the statements given above is/are correct?

• A. 1 and 2 only
• B. 2 only
• C. 2 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is D 1, 2 and 3

Explanation:

All of the statements are correct.

On December 7, 2021, NASA launched a new Laser Communications Relay Demonstration (LCRD).

Key features:

• It is the first-ever laser communications system of NASA.
• LCRD will help NASA in testing optical communication in space.
• As of now, most of the NASA spacecraft use radio frequency communications to send data.
• Optical communications will help in increasing the bandwidth by 10 to 100 times as compared to radiofrequency systems.
• LCRD will also demonstrate all of the advantages of using laser systems.
• With this technology, laser communications can be implemented on more missions in a bid to standardize ways to send and receive data.
