S03E136: Starbase Milestones, Space Junk Solutions, and Astronaut Adventures

Astronomy Daily - The Podcast

Welcome to Astronomy Daily, your go-to Podcast for the latest news and insights in the world of space and Astronomy. I'm your host, Anna. Today we'll start with SpaceX's rapid progress at Starbase, where they're making significant advances with their launch towers and preparing for future missions. Then we'll move on to a fascinating new initiative from Japanese company Astroscale, which aims to tackle the growing problem of space junk with an innovative $90 million mission. Next, we'll dive into some exciting research being conducted on the International Space Station by NASA astronauts Butch Wilmore and Suni Williams. Finally, we'll explore Harvard professor Avi Loeb's intriguing hypothesis about how advanced civilizations might use black holes as a power source. Let's dive in.
- **SpaceX's Rapid Progress at Starbase**: SpaceX has done it again. They've stacked launch tower two at orbital launch pad B at Starbase, Texas, in record time. This rapid assembly, completed in just 41 Daily, is an impressive feat of engineering and logistics, setting the stage for their innovative chopstick system designed to catch boosters mid-air.
- **Astroscale's $90 Million Space Junk Removal Mission**: Japanese company Astroscale recently secured a $90 million contract to remove a bus-sized rocket stage from orbit. This mission, funded by the Japanese Aerospace Exploration Agency (JAXA), is a significant step forward in space sustainability. Astroscale's project, named ADRAS-J2, aims to tackle the issue of space debris head-on, using advanced robotic technologies to clean up our orbits. The mission involves using a robotic arm to grab the tumbling rocket stage and pull it into Earth's atmosphere, where it will burn up on reentry.
- **Exciting Research on the ISS**: NASA astronauts Butch Wilmore and Suni Williams have been conducting groundbreaking research on the International Space Station (ISS). Their work includes experiments on plant growth in space, fluid physics, and utilizing Astrobee, a set of free-flying robots designed to assist with chores and maintenance.
- **Avi Loeb's Black Hole Moon Hypothesis**: Harvard professor Avi Loeb has sparked intriguing discussions with his latest hypothesis, the Black Hole Moon. This groundbreaking idea suggests that advanced civilizations could exploit black holes as potent energy sources, potentially providing a technosignature detectable from Earth. Loeb builds upon Roger Penrose's concept of extracting energy from a rotating black hole's accretion disk and proposes the creation or capture of a small black hole weighing about 100,000 tons. This black hole could emit a massive continuous energy output through Hawking radiation, potentially powering an entire planet and even consuming waste. Detecting such a system could revolutionize our search for extraterrestrial intelligence.
