Researchers at Massachusetts Institute of Technology's (MIT) Lincoln Laboratory have developed a new data communication technology between Earth and the moon which can allow space dwellers to transfer large amounts of data and stream high definition videos.
Mark Stevens of MIT Lincoln Laboratory said that this will be the first time that they will present both the implementation overview and how well it actually worked and the on-orbit performance was excellent and close to what they predicted.
Stevens added that communicating at high data rates from Earth to the moon with laser beams was challenging because of the 400,000-kilometer distance spreading out the light beam, and it was twice as difficult going through the atmosphere, because turbulence could bend light that would cause rapid fading or dropouts of the signal at the receiver.
Steven said that they demonstrated tolerance to medium-size cloud attenuations, as well as large atmospheric-turbulence-induced signal power variations, or fading, allowing error-free performance even with very small signal margins.
