Why do Artemis 2 photos and livestream have so much delay compared to the Apollo Broadcast in 1969? NASA’s Artemis II mission was sending photos and live streaming 4K video from the moon 400,000 km through space over NASA’s O2O infrared laser capable of 260 megabits per second. So why is the Artemis broadcast more delayed than NASA’s live broadcasts of the Apollo Moon Landing were 50 years ago?
Since the Artemis 2 photos and livestream are digital, compression, error correction, re-encoding for YouTube, and streaming buffers each add latency that didn’t exist when everything was analog. But this also means NASA’s 4K Moon footage from Artemis is much clearer than what the Apollo moon missions gave us.
We also get into Kessler syndrome: how one exploding Starlink satellite could trigger a chain reaction of space debris that locks humanity out of space for three years, and how Starlink is trying to prevent it with a live 3D map of every object in orbit.
