Post navigation NASA astronauts from the International Space Station will be communicating with students in Oklahoma and Texas to share their experiences in space. This conversation will be streamed remotely to other students and teachers around the world as part of NASA’s Year of Education on Station program. Through this program, NASA aims to inspire students to pursue STEM careers and increase student engagement in space exploration. A 300,000 year old skull was discovered in China and shows a mix of features belonging to both very early humans and Neanderthals. The skull is much older than the initial migration out of Africa and suggests a more complex history of early humans. It challenges existing theories of early human evolution and suggests more varieties of early people may be out there.
