Let’s learn about Mars
Traveling to Mars offers many challenges, including life without gravity, cosmic rays and communication delays.
- Space
Scientists Say: Gravity
Gravity is a fundamental force that attracts objects with mass to other objects with mass. It decreases with distance.

Let’s learn about space robots
Space robots can take pictures of other planets, analyze samples of their surface and even peer into their interiors.

Saturn’s moon Titan may host lots of dried lakes
Suspicious spots around the moon’s middle could be the beds of ancient lakes. If so, this might solve a 20-year-old mystery.

Developing planet emerges in a swirl of gas
Images of a young star 520 light-years away show a spiral of gas and dust swirling around it. A twist inside the spiral appears to be a planet forming.

Wiggly wheels might help rovers plow through loose lunar soils
New design lets wheels ascend hills too steep for regular robots and paddle through loose soils without getting stuck.
