GOLDEN VALLEY, Minn. - Next week NASA begins work on solving a 4 billion-year-old question.
Four billion years ago Mars may have looked a lot like Earth with blue skies and balmy temperatures. It likely had an atmosphere as thick as the Earth's that not only may have sustained flowing water, but possibly even supported life.
On November 18, the Maven orbiter is launching to Mars to study planet's atmosphere and find out why Mars lost its water.
NASA scientist, Michelle Thaller, joined KARE 11 live from Goddard Space Flight Center in Greenbelt, Maryland to talk about Mars' climate change.
