#155 - La radio entre la Tierra y la Luna: Artemis II y sus comunicaciones

As we record this episode, a crewed spacecraft from the Artemis program is traveling toward the Moon. But beyond the rocket, the capsule, or the mission itself… there is something much quieter and absolutely critical: the communications link. How do you maintain a conversation almost 400,000 kilometers away? What makes it possible for a signal to arrive, be received, and be understood under extreme conditions? In this episode, we explore the real foundations of space communications: the operating bands (S, X, and Ka), the infrastructure that supports it all on Earth, and the physical limitations faced by any radio link in deep space. And we do so from a very relatable perspective: the parallel with lunar bounce (EME). Because what happens in Artemis isn't magic… it's the same radio we use, pushed to its limits. We also analyze the role of new technologies like the O2O system, based on laser communications, which promises to multiply the amount of data transmitted from the lunar environment without replacing—at least for now—traditional radio. An episode about faint signals, extreme precision, and one fundamental idea: that from a ham radio station… to a manned mission around the Moon, it all boils down to the same thing. That a signal arrives. Will you support us so we can continue making this podcast?
