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.
