Ep. 707: What Goes Into Sample Return Missions for the Moon and Mars?

Ep. 707: What Goes Into Sample Return Missions for the Moon and Mars?

We’ve sent robots to other worlds, but the amount of science we can deploy to another planet can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return, bringing pieces of alien worlds back to Earth, were we study them with proper equipment.

Ep. 706: China’s Space Program

Ep. 706: China’s Space Program

We’re so familiar with NASA’s exploration efforts in space, but you might be surprised to learn that China launches almost as many rockets as the US. They’ve got their own space exploration program that could soon bring humans to the surface of the Moon. Let’s give a brief overview of China’s space exploration plans.

Ep. 705: Water Worlds – Looking for Life Beyond Earth

Ep. 705: Water Worlds – Looking for Life Beyond Earth

Wherever we find liquid water on Earth, we find life, so it makes sense to search for water across the Universe, and hopefully we can find evidence of life. But what about worlds which are completely covered in water, oceans hundreds of kilometers deep. Can there be too much water?
