After three Earth years on Mars, the Curiosity rover has found extensive evidence of past liquid water in Gale Crater. Check out some of the highlights.
Scientists are developing a novel space robot that can take up the challenge of hopping and rolling over microgravity terrain while doing valuable science.
What tiny satellites could take a ride over to Europa? Here are five feasibility studies being considered to hitchhike on a NASA mission.
New Horizons survived 9.5 years in space before taking pictures of Pluto. How do spacecraft engineers keep their machines going for so long?
Mars rover Opportunity has recommenced driving duties and continues to explore the red planet despite a series of recent setbacks focusing on its aging memory.
As multi-million dollar spacecraft crawl across our solar system, they could bring smaller passengers with them -- these tiny vehicles are called CubeSats and they've so far done a great job colonizing low Earth orbit.
