Planning Space Missions of the Future

The European Space Agency recently outlined its “themes” for space exploration in the future, outlining humanity’s top priorities in space. 

An artificial sun?

A new nuclear reactor in China debuted late last year, and is able to reach temperatures hotter than the sun.

What if an elephant fell from the Empire State Building?

Future spacecraft - and how they will handle landing on new planets

Scientists have already landed spacecraft on the easier, calmer planets – now they have to figure out how to get their machines onto planets with high pressured atmospheres, steep, mountainous surfaces, and slippery ice surfaces

A device can produce energy using shadows

A new device exploits the contrast between bright spots and shade to create a current that can power small electronics. 

Fish save energy by swimming in schools

Robot-like fish provided insight to researchers and scientists who were interested in the effects other fishes’ swimming on a member of the school.
