The funny thing is that a technology that takes us a little more than a century, x-rays, can be the answer to all our space problems. With technologies based on them, we could transmit gigabits per second through the solar system and even create the ultimate interstellar navigation system. And it’s not just a theory, now the NASA Goddard Center prepares for the first demonstration of this technology in space.
