laser signal

On October 3, NASA's Psyche spacecraft successfully transmitted a laser signal from Mars orbit to Earth, marking an important milestone in the mission to launch this spacecraft

Learners at the European Space Agency (ESA) said the Herschel space telescope found two mysterious laser streams originating from a rare binary star system called the Ant Nebula.

For the first time, scientists have demonstrated the ability to transmit wireless Internet signals with a distance of 238,900 miles, the distance from the earth to the moon.
