Chinese scientists have landed a spacecraft on the far side of the moon. Rachel Martin speaks with Brown University planetary scientist James Head about whether it is a big milestone.
China's space program has landed a wheeled rover on the far side of the moon that's never seen from Earth. It's part of a systematic plan that the country has for space exploration.
China's astronomical ambitions are not purely scientific. NPR's Mary Louise Kelly talks with U.S. Naval War College Professor Joan Johnson-Freese about China's larger geopolitical strategy.
Lunar lander Chang'e 4 successfully touched down on Thursday morning. China's Xinhua News published a photo it says was taken by the probe "on the never-visible side of the moon."

Congressional leaders go to the White House for a border security briefing. A U.S. citizen is in Russian custody on suspicion of spying. And, NASA's New Horizons probe makes history.
Queen guitarist Brian May is also an astrophysicist. He consulted with NASA on its New Horizons probe, which this week started sending back signals from the outer reaches of our solar system.
NASA's New Horizons flew by the most distant object ever visited by a spacecraft Tuesday. NPR's Audie Cornish talks with planetary scientist Heidi Hammel about what data from the fly by shows.
The first images of the object, just a few pixels wide, arrived Tuesday morning. Higher-resolution photographs will be sent back to Earth in the coming weeks.
Early in 2019, China hopes to land a rover — the first soft landing on the moon's far side. The mission is exploratory, and will lay groundwork for a trip by Chinese astronauts to the lunar surface.

Earth may not be the only place in our solar system with life, says James Green. New data shows life might have existed on Mars, and could exist now. But what does that mean for us on Earth?

Lucianne Walkowicz is all for space exploration, but says we shouldn't expect Mars to save us from a damaged Earth. She warns us not to lose sight of preserving the home we already have.
