In this episode of SpaceTime, we uncover groundbreaking discoveries and updates from the cosmos. First, NASA's Curiosity Rover has revealed evidence of a carbon cycle on Mars, with significant carbon deposits found in Gale Crater. This finding, detailed in the journal Science, brings researchers closer to understanding Mars's potential to support life in its past. We discuss the implications of these findings and what they mean for the Red Planet's climatic history and habitability.

Square Kilometer Array Update

Next, we provide an exciting update on the billion-dollar Square Kilometer Array (SKA) project, the world's largest radio telescope currently under construction in Australia and South Africa. We explore how this massive facility will revolutionize our understanding of the universe, operating at unprecedented speeds and sensitivities. With 132,000 antennas spread over vast distances, the SKA aims to answer fundamental questions about gravity, magnetism, and the evolution of galaxies.

Busy Times at the International Space Station

Finally, we take a look at the bustling activity aboard the International Space Station. With recent crew returns and new cargo deliveries, including groundbreaking experiments on time measurement and gravitational research, the ISS continues to be a hub of scientific advancement. We discuss the latest missions and what they mean for future exploration and research in space.
