NASA is advancing towards a pivotal test of end-to-end laser communication in the realm of space. This cutting-edge communication system is poised to outperform conventional methodologies currently utilised aboard the International Space Station (ISS). The implementation of advanced technologies, including an integrated Low Earth Orbit User Modem and Amplifier Terminal named LCDR, is slated for this year’s launch.
This strategic move underlines NASA’s dedicated endeavours to augment the capabilities of space communications. With over two decades of facilitating significant scientific research, the ISS’s orbital presence around Earth remains paramount. The imminent launch of the amplifier terminal, aptly named ILLUMA-T, is scheduled for December 2021. This event will mark a milestone as NASA takes a significant stride in realising the pioneering two-way, end-to-end laser relay system. This endeavour emerges from a collaborative effort alongside the Laser Communications Relay Demonstration.
The essence of laser communication systems lies in their utilisation of infrared light, which yields heightened data rates. This innovative approach facilitates the transmission of a greater volume of images and videos to Earth within a singular transmission event. The ramifications of such developments are especially intriguing for low-orbit missions, which are further emphasised by their placement inside the space limits of the ISS.
