Mars’ Atmospheric Erosion

Scientists have long suspected the solar wind of stripping the Martian upper atmosphere into space, turning Mars from a blue world to a red one. Now, NASA’s MAVEN orbiter is observing this process in action, providing significant data on solar wind erosion at Mars.

China’s Moon: Journey of the Jade Rabbit

Yutu, or “Jade Rabbit,” is an unmanned lunar rover that was part of the Chinese Chang’e 3 Moon mission. It reached the lunar surface in mid-December 2013. It was the first soft landing on the Moon since 1976, and the first rover to operate there since the Soviet Lunokhod 2 mission ended in May 1973.

Yutu encountered operational difficulties after about a month on the Moon, and was unable to move after the end of the second lunar night. It continued to gather useful information for some months afterward. In October 2015, Yutu set the record for the longest operational period for a rover on the Moon.

Neptune Through the Eyes of Kepler

In late 2014 and early 2015, NASA’s Kepler telescope observed the eighth planet in our solar system, Neptune. Kepler detected Neptune’s daily rotation, the movement of clouds, and even minute changes in the sun’s brightness, paving the way for future studies of weather and climate beyond our solar system.

SuperTornado: Anatomy of a MegaDisaster

May 22nd, 2011. A powerful tornado cut a mile-wide swath through Joplin, Missouri. It was the costliest tornado disaster in history, with insured losses close to two billion dollars. It was also one of the deadliest, with 161 lives lost… and one thousand injured.

The scale of the Joplin disaster drew teams of scientists hoping to find out what made this storm so destructive. And what can be done to protect communities and people in the future. What did they learn by peering inside the violent realm of a Super Tornado?
