See NASA’s next Mars rover quite literally coming together inside a clean room at the Jet Propulsion Laboratory. This behind-the-scenes look at what goes into building and preparing a rover for Mars, including extensive tests in simulated space environments, was captured from March to July 2019. The rover is expected to launch to the Red Planet in summer 2020 and touch down in February 2021.

The Mars 2020 Rover is preparing to launch to the Red Planet in July 2020, but it doesn't have a name yet. We're asking K-12 students across the United States to send in essays with their best name ideas by Nov. 1, 2019.

What can you see this month? In the August sky, look for the "shooting stars" of the annual Perseid meteor shower for some stargazing delights, but be warned — the bright Moon will overwhelm the fainter meteors this year. Plus, the Moon's evening visits to Jupiter and Saturn.

A team of engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, install the legs and wheels — otherwise known as the mobility suspension — on the Mars 2020 rover. The imagery for this accelerated time-lapse was taken on June 13, 2019, from a camera above the Spacecraft Assembly Facility's High Bay 1 clean room.

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.
