SpaceTime with Stuart Gary Gary - Series 29 Episode 8

In this episode of SpaceTime , we investigate the surprising ways Mars influences Earth's climate, hear about the safe return of Crew 11 following the first emergency medical evacuation from the International Space Station, and explore a cosmic clock that reveals insights into Australia's geological history.

Mars: A Climate Influencer

A new study has unveiled that the orbit of Mars can significantly impact Earth's climate, even triggering ice ages. Researchers from the University of California Riverside utilized computer simulations to demonstrate how Mars’ gravitational pull alters Earth's orbit and affects long-term climatic cycles. The findings challenge previous assumptions about Mars' minimal influence and highlight the planet's role in shaping Earth's climatic patterns over millions of years.

Crew 11's Safe Return

NASA's SpaceX Crew 11 has successfully splashed down in the North Pacific Ocean after a historic emergency medical evacuation from the ISS. The crew's return, which occurred a month earlier than planned due to medical concerns, was marked by a brilliant display in the night sky as they descended. This marks a significant event in the history of human spaceflight, emphasizing the importance of health monitoring aboard the space station.

Unveiling Australia's Geological History

Scientists have discovered that the rare gas krypton can be used to unlock the secrets of Earth's ancient landscapes. By examining tiny zircon crystals found in ancient beach sands, researchers can gauge how long these minerals have been exposed at the surface, providing insights into erosion rates and potential mineral deposits. This groundbreaking research not only sheds light on the past but also has implications for future resource exploration in Australia.
