Liquid Water on Mars: A Mirage?
A new study casts doubt on the existence of liquid water on Mars, challenging previous assumptions about recurring slope lineae and the potential for brine pools. Researchers argue that the Martian environment's low temperature and pressure make it unlikely for liquid water to exist, even in the form of salty brines. The findings question the habitability of the Red Planet by Earth standards.
New Asteroids Discovered
NASA's Webb Space Telescope has identified a new population of small main belt asteroids between Mars and Jupiter. These 138 newly discovered celestial bodies range in size from a bus to a football stadium, offering insights into asteroid formation and the potential risks of asteroid impacts on Earth.
Australia's Lunar Rover Project Advances
Australia's first Lunar Rover project is moving forward with the development of prototype rovers and essential technology to tackle lunar dust challenges. Supported by the Australian Space Agency, this $42 million initiative aims to enhance Australia's role in lunar exploration.
