SpaceTime Series 28 Episode 26
The Astronomy, Space and Science News Podcast
Asteroid Ryugu's Salty Secrets, Solar Orbiter's Venus Encounter, and NASA's Lunar Resource Exploration
In this episode of SpaceTime, we delve into the recent findings from the asteroid Richie, where scientists have discovered evidence of salt minerals, hinting at the presence of saline water in the outer solar system. This exciting revelation parallels previous discoveries from asteroid Bennu and enhances our understanding of the chemical history of these celestial bodies.
Europe's Solar Orbiter and Venus
We also explore the European Space Agency's Solar Orbiter spacecraft as it prepares for a close flyby of Venus. This maneuver will allow the spacecraft to adjust its orbit significantly, enabling unprecedented observations of the Sun's polar regions, which have remained elusive from Earth. The encounter will provide critical data to improve our understanding of solar activity and its impact on space weather.
NASA's Polar Ice Experiment
Additionally, we discuss NASA's Polar Resources Ice Mining Experiment (PRIME 1), which aims to analyze the Moon's subsurface for potential resources. This mission is pivotal for future manned lunar explorations under the Artemis program, as it seeks to identify local resources that can support sustained human presence on the Moon.
