For millennia, our communication was tethered to the physical world. You could either talk to someone directly or rely on a messenger on foot, horse, or a sailing ship to send a letter. The invention of the telegraph and radio changed all that. Suddenly, we could communicate to someone on the other side of the world. We wrapped the globe in signals that travel at the speed of light and today, our communications can reach almost any corner of the planet in a variety of different ways.

A final frontier that has opened up in our quest to extend our communications pathways is space.

This week at the HLFF Blog, Andrei Mihai looks at NASA’s Deep Space Optical Communications (DSOC) program, which managed to send video via a laser-based transmission system at incredible speeds from over hundreds of millions of kilometers away.
