NASA uses lasers to send information to and from Earth, employing invisible beams to traverse the skies, sending terabytes of data – pictures and videos – to increase our knowledge of the universe. This capability is known as laser, or optical, communications, even though these eye-safe, infrared beams can’t be seen by human eyes.
“We are thrilled by the promise laser communications will offer in the coming years,” says Badri Younes, Deputy Associate Administrator and Program Manager for Space Communications and Navigation (SCaN) at NASA Headquarters in Washington. “These missions and demonstrations usher in NASA’s new Decade of Light in which NASA will work with other government agencies and the commercial sector to dramatically expand future communications capabilities for space exploration and enable vibrant and robust economic opportunities.”
