Space.com: As of 15 December, NASA’s Odyssey orbiter became Mars’s longest-running mission. The satellite has been orbiting Mars for 3340 days, passing the record previously set by the Mars Global Surveyor. It was Odyssey that discovered water ice under Mars’s surface, only a few months into its mission. It also monitored Mars’s radiation levels to determine the feasibility of human exploration. Although Odyssey completed its primary mission in 2004, it continues to work, monitoring long-term climate patterns and capturing images of the planet’s surface to create a high-resolution global map.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
