This episode of SpaceTime covers a range of exciting topics, including the delayed launch of Gilmour Space's Eris rocket, groundbreaking discoveries on Venus, and a billion-year-old asteroid impact in Scotland that raises new questions about the evolution of life on Earth. Eris Rocket Launch Delayed Gilmour Space has postponed the maiden launch of its Eris orbital rocket due to technical issues encountered during pre-flight checks. The rocket, designed to carry small satellite payloads, will now face a delay of at least three weeks as the company investigates the unexpected deployment of the launch vehicle's nosecone fairings. We discuss the implications of this delay and what it means for future commercial launches. Tectonic Activity on Venus In a fascinating discovery, scientists have identified possible tectonic activity on Venus, based on data from NASA's Magellan mission. Researchers found evidence of unique geological features known as coronae, which may indicate ongoing deformation of the planet's surface due to molten material from below. This research not only enhances our understanding of Venus but also offers insights into Earth's geological history. Ancient Asteroid Impact in Scotland A recent study has revealed that a massive asteroid impact in Scotland occurred 990 million years ago, much later than previously thought. This discovery, based on dating tiny zircon crystals, suggests a connection between this impact event and the emergence of early freshwater eukaryotes on land. We delve into the implications of this revised timeline for our understanding of life on Earth and the environmental changes triggered by such impacts. www.spacetimewithstuartgary.com ✍️ Episode References Science Advances https://www.science.org/journal/sciadv Journal of Geology https://www.geosociety.org/publications/gsa/geo.asp Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support . 00:00 This is Space Time Series 28, Episode 60 for broadcast on 19 May 2025 00:54 Gilmour Space's Eris rocket launch delayed 10:15 Possible tectonic activity discovered on Venus 18:45 Billion-year-old asteroid impact in Scotland raises questions about early life on Earth 25:00 Science report: Unexplained communications equipment found in Chinese-made solar panel inverters…

This episode of SpaceTime dives deep into the intriguing findings from Mars, the peculiar behavior of a family of stars, and the latest developments in NASA's Artemis program. Possible Martian Biosignatures Scientists are captivated by the potential detection of biosignatures in a rock sample named Chayava Falls, collected by NASA's Perseverance rover. This rock, filled with unique chemical signatures, raises questions about the possibility of ancient microbial life on Mars. The analysis reveals organic compounds and distinctive structures, prompting further investigation to determine their origins and implications for past life on the Red Planet. Strange Stellar Family In an unexpected discovery, astronomers have identified a cluster of over a thousand young stars, named Ophion, that are behaving in a chaotic manner, rapidly dispersing instead of forming stable groups. This unusual behavior challenges existing theories about star formation and raises questions about the influences of nearby massive stellar groups and past supernovae on their movement. Artemis 2 Orion Capsule Delivered The Orion capsule designated for NASA's Artemis 2 mission has officially been handed over to NASA after final assembly and testing. This advanced spacecraft is set to carry a crew of four on a mission to orbit the Moon, marking a significant step towards future lunar exploration. We discuss the enhancements made to Orion since Artemis 1 and the preparations for its upcoming launch. www.spacetimewithstuartgary.com ✍️ Episode References Astrophysical Journal https://iopscience.iop.org/journal/0004-637X NASA Perseverance Rover https://mars.nasa.gov/mars2020/ NASA Artemis Program https://www.nasa.gov/artemis Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support . 00:00 This is Space Time Series 28, Episode 59 for broadcast on 16 May 2025 00:54 Possible biosignatures detected on Mars 12:15 The unusual behavior of the Ophion star cluster 20:30 Artemis 2 Orion capsule delivered to NASA for preparations 25:00 Science report: Technology use around children and its effects on health…
