SpaceTime Series 27 Episode 135
*Could Uranus Moon Miranda Have a Subsurface Ocean?
A new study suggests that Uranus' moon Miranda may harbour a liquid water ocean beneath its peculiar jigsaw-like surface. The findings, published in the Planetary Science Journal, challenge existing assumptions about Miranda's history and composition, potentially placing it among the select few worlds in our solar system with environments that could support life. The study highlights the intriguing possibility of a vast ocean beneath Miranda's icy crust, kept warm by gravitational tidal forces.
*NASA Discovers Weird Red Rocks with Green Spots on Mars
NASA's Mars Perseverance Rover has stumbled upon strange red rocks with green spots on the Martian surface. As the rover continues its journey towards the rim of Jezero Crater, it has uncovered a new geological puzzle featuring red and green rocks. Scientists are intrigued by the green spots, which could suggest past water activity, but their exact composition remains a mystery due to the rover's current limitations.
*First Humans on Mars by 2035?
NASA is planning to send humans to Mars as early as 2035. The mission would be part of the Artemis programme, with a journey that could take up to 14 months, including a 500-day stay on the Martian surface. This ambitious plan hinges on the successful deployment of the Lunar Gateway Space Station and other key technologies.
