Laser Communications Relay Demonstration (LCRD) Overview

NASA is advancing space communication with the Laser Communications Relay Demonstration (LPRD), which uses near-infrared lasers to transmit data more efficiently than traditional radio waves. This technology allows for higher data rates, enabling the transmission of larger files and live HD video from space. Laser systems are smaller, more energy-efficient, and cheaper to launch, benefiting both spacecraft and ground receivers. The LPRD is a step towards integrating laser communication into future NASA missions and sharing it with commercial entities, pushing the boundaries of scientific exploration.

What is the primary goal of the Laser Communications Relay Demonstration (LPRD)?

• To develop new energy sources

• To test new spacecraft designs

• To improve data transmission from space to Earth

• To explore new planets

How much more data can laser communications transmit compared to previous systems?

• 200 times more

• 100 times more

• 50 times more

• 10 times more

What is one benefit of laser communication systems over radio wave technology?

• They are larger in size

• They require more energy

• They are more expensive to launch

• They are more efficient and smaller

How much smaller can Earth-based laser communication receivers be compared to current radio antennas?

• Up to 10 times smaller

• Up to 44 times smaller

• Up to 60 times smaller

• Up to 20 times smaller

What is NASA's plan for laser communication technology in the future?

• To abandon it for newer technologies

• To integrate it into future missions and share with commercial companies

• To limit its use to Earth-based applications

• To use it only for military purposes
