Communication is an essential capability all spacecraft require for scientific exploration of space. Whether in Earth orbit or distant regions of our solar system, a two-way connection between ground stations and flight missions enables commanding, navigation, and transmission of telemetry and scientific data. For decades, NASA has relied on a mature network infrastructure based on radio frequency (RF) technology. Now, a new approach using laser light is being developed for its potential to significantly increase the speed of communication allowing much more data to be returned from our observations of Earth and other planets.
This short course will explain the key principles behind optical communication, and provide a historical review of the achievements of NASA, the European Space Agency, and Japan’s National Institute of Information and Communication Technology to demonstrate its functionality on satellites. The advantages that communications with lasers can provide to future space missions will be discussed, as well as the outstanding challenges and risks that must be addressed in order to realize this goal. This course is open to JPL and Caltech staff, faculty, and students, and will be presented by a diverse group of scientists, engineers, and professors with experience in the field.
