Laser beams turn moon into Wi-Fi hotspot


The plan of living on the moon may still be a distant dream, however visitors orbiting the moon will now be able to access internet.

For the past one year, a team of scientists has been shooting laser beams at the moon, and now the moon has turned into a Wi-Fi hotspot where visitors can get access to internet.

Last year, members of Massachusetts Institute of Technology (MIT) and NASA made history when the Lunar Laser Communication Demonstration (LLCD) transmitted data over the 384,633km distance that separates moon and the earth.

When LLCD transmitted data at 19.44 megabits per second, it is not only faster than the best satellite uplink utilized in the past, but it is much faster than the standard internet speed in South Africa.

According to Mark Stevens from the MIT Lincoln Laboratory, “It’s doubly difficult going through the atmosphere because turbulence can bend light, causing rapid fading or dropouts of the signal at the receiver.”898561444

It might be groundbreaking, but it does involve the glitches and kinks that tend to mar the majority of wireless internet connections.

According to basic number crunching, there will be a 3-second delay between the data being transmitted and received along the laser beam.

The connection was made utilizing 4 separate telescopes positioned at ground terminal at White Sands in New Mexico. The diameter of each telescope is 15cm, and is powered by a laser transmitter that sends data coded as pulses of infrared light.

Four telescopes were utilized to confirm the signals have made it to the receiver, placed on a satellite orbiting the moon.

It must be noted that the new technique is 4800 times faster than any other, and the findings will be unveiled publicly by the team this weekend.
