Interplanetary Communication and Laser Technology

What is the main limitation of the NASA Deep Space Network (DSN) that the new system aims to overcome?

• It is based on outdated satellite technology.

• It is too expensive to maintain.

• It relies on radio waves established in 1963.

• It cannot communicate beyond Earth's orbit.

What is one of the key advantages of using lasers over radio waves for space communication?

• Lasers are less affected by Earth's atmosphere.

• Lasers can carry more information per second.

• Lasers are cheaper to produce.

• Lasers can travel faster than radio waves.

Why do radio waves have a lower carrying capacity compared to lasers?

• They require more power to transmit.

• They are slower than light.

• They have longer wavelengths.

• They are absorbed by space dust.

What is a disadvantage of using lasers for space communication?

• Lasers require precise aiming.

• Lasers are slower than radio waves.

• Lasers cannot travel through space.

• Lasers are more expensive than radio waves.

What was a significant milestone in extraterrestrial laser communications achieved in 1968?

• First use of lasers for television broadcast.

• First laser communication with Mars.

• Detection of Earth-originating lasers by Surveyor 7.

• First laser communication with a satellite.

What was the content of the video sent back by the Psyche spacecraft during its test?

• A video of a spacewalk.

• A video of an orange cat playing with a laser pointer.

• A video of the Earth from space.

• A video of the Mars surface.

What is the expected data transmission rate of the Psyche Mission's laser communication system?
