863-Space Elevator

Author: Albert D. Grauer August 22, 2025 Duration: 2:01
In a recent study Dr. Lynnane George and her co-authors investigate Space Elevator technology to remove materials from Ceres and deliver them to orbital depots around the solar system.  The tiny gravity of Ceres, nano-fiber technology, and different water propulsion systems are utilized by Dr. George and her team to construct theoretically possible systems which would extract raw materials from Ceres and deliver them to low Earth orbit and other locations within the solar system.  These researchers estimate such a transport system could reduce fuel costs by up to 60% compared to transport from the Earth’s surface. 

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.
