SpaceTime Series 28 Episode 33 The Astronomy, Space and Science News Podcast World's Oldest Meteor Impact Crater, Water Ice on the Moon, and the Secretive X37B Shuttle Returns In this episode of SpaceTime, we unveil the discovery of the world's oldest known meteor impact crater located in Western Australia. This ancient structure, dating back 3.5 billion years, was identified in the Pilbara region and challenges previous notions about Earth's geological history and the origins of life. We discuss the implications of this significant find, including its potential to reshape our understanding of crust formation and the environments conducive to early microbial life. Water Ice on the Moon We also delve into exciting new research suggesting that water ice may be found just centimeters below the lunar surface across a much larger area of the Moon's polar regions than previously believed. Based on observations from India's Chandrayaan 3 mission, these findings could greatly influence future lunar exploration and habitation efforts, highlighting the potential for accessible sources of water ice. The X37B Space Shuttle's Secret Mission Additionally, we cover the return of the United States Space Force's X37B space shuttle after a classified 434-day mission. The shuttle's successful landing at Vandenberg Space Force Base marks another milestone in its ongoing operations, which include specialized testing and reconnaissance in orbit. We explore the implications of this mission for national security and the future of space operations. 00:00 Space Time Series 28 Episode 33 for broadcast on 17 March 2025 00:49 Discovery of the world's oldest meteor impact crater 06:30 Implications for Earth's geological history 12:15 Overview of potential water ice locations on the Moon 18:00 Findings from the Chandrayaan 3 mission 22:45 Return of the X37B space shuttle 27:00 Summary of recent scientific developments 30:15 Discussion on advancements in HIV prevention www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) www.bitesz.com (https://www.bitesz.com/) 🌏 Get Our Exclusive NordVPN deal here ➼ www.bitesz.com/nordvpn (https://www.bitesz.com/nordvpn) .
