LEMUR belongs to a new generation of robots being built by NASA's Jet Propulsion Laboratory that can crawl, walk and even climb rock walls.

The Mars 2020 mission is facing the most challenging landing yet on the Red Planet. It will touch down on Feb. 18, 2021, in Jezero Crater, a 28-mile-wide (45-kilometer-wide) expanse full of steep cliffs, boulder fields and other things that could boobytrap the landing. A new technology called Terrain Relative Navigation (TRN) will allow the spacecraft to avoid hazards autonomously.

As NASA marks the 50th anniversary of the Apollo 11 Moon landing, here are five things to know about the Moon that you can share with others: How far away is the Moon? How big is the Moon? What color is the Moon? Why do we always see the same side of the Moon? And what are the dark areas on the Moon?

Can we fly on Mars?

The laws of physics may say it's near impossible, but actually flying a heavier-than-air vehicle on the Red Planet is much harder than that. NASA’s Mars 2020 mission will deliver a technology demonstration that will put the idea to the test -- a helicopter that will perform controlled flight on Mars.

NASA InSight scientist/engineer Troy Hudson gives us the game plan for getting the mission's heat probe, also known as the "mole," digging again on Mars.

What's up in the June sky? Jupiter is at its biggest and brightest, Mercury and Mars appear ultra-close and how you can observe the Moon's tilted orbit.

Soar through this cosmic landscape filled with bright nebulas, as well as runaway, massive and young stars.

After spending the better part of a year exploring Mars' Vera Rubin Ridge, NASA's Curiosity Mars rover has moved to a new part of Mount Sharp. Project Scientist Ashwin Vasavada gives a tour of the rover's new home in the "clay unit," as well as other areas scientists are excited to visit.

What's up in the May sky? A meteor shower produced by debris from Halley's Comet, asteroids named after dinosaurs and a "blue moon" on May 18th.

NASA's OCO-3 mission is ready for launch to the International Space Station. This follow-on to OCO-2 brings new techniques and new technologies to carbon dioxide observations of Earth from space.
