910-Mega Constellations

910-Mega Constellations

Author: Albert D. Grauer July 31, 2026 Duration: 2:01
In an experiment that will involve all of the residents of planet Earth SpaceX has asked the FCC for permission to launch 1 million satellites into low Earth orbit to create a solar powered data center. Since the agriculture which produces our food is very sensitive to weather and climate it is important to conduct serious research about the effect of a mega constellation of satellites before allowing such a project to produce changes to the environment we don’t understand. 

Each episode of Travelers In The Night feels like a quiet, personal conversation under a dark sky. Hosted by astronomer Dr. Albert D. Grauer, this podcast brings the distant cosmos into sharp, intimate focus. Dr. Grauer isn't just an observer; he's an active participant in the hunt, working with the Catalina Sky Survey team that has consistently discovered near-Earth asteroids for years. In these brief and engaging segments, you'll hear firsthand accounts of what it's like to track these ancient celestial travelers-the asteroids and comets that silently pass by our world. The discussions move beyond simple facts to explore the real-world implications of these discoveries, from planetary defense to the sheer wonder of our dynamic solar system. Accompanied by the contemplative music of John Lyell's "Eternity," each installment offers a moment of calm reflection on humanity's place in the universe. It’s a perfect blend of grounded science and cosmic curiosity, making complex astronomical concepts accessible and deeply fascinating. For anyone who has ever looked up and wondered what's out there moving in the dark, this podcast provides a direct line to the front lines of discovery.
