   A miniature rover being developed to explore the Moon's surface is on track to join the search for water there, its Hungarian inventors believe - using a device that weighs less than a bag of sugar. Named after a Hungarian breed of dog, the Puli rover is a low-cost platform designed to carry different payloads, including the ice water snooper, which won the 2020 "Honey, I Shrunk the NASA Payload" challenge, a competition organised by the US space agency.

   "It looks for background radiation and then the background radiation induces a secondary radiation coming out of the Moon," said Matyas Hazadi, head of technical engineering at Budapest-based Puli Space Technologies Ltd, which developed both it and the rover. (Reuters Photo)

   The rover has four independently steerable wheels formed of foot-like rubberised spokes and can scale 40-45 degrees slopes, and its prototypes have been tested on lunar-like terrain in Hawaii and Morocco. (Reuters Photo)
