By refueling in orbit and helping slow the spacecraft on arrival, it could cut travel time nearly in half. That’s a big deal for a mission that would otherwise take over a decade just to arrive. If it works, it could finally open the door to studying this strange, tilted world up close.

A vision-capable AI analyzed the same images and terrain data normally used by rover planners, identified hazards like rocks and sand ripples, and charted a safe path across the Martian surface. After extensive testing in a virtual replica of the rover, Perseverance successfully followed the AI-generated routes, traveling hundreds of feet autonomously.

And now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.

The models suggests that explosions of warming nitrogen created basins in the moon's crust.

The faults are likely the result of the moon's interior cooling and shrinking, causing the surface crust to shrivel and crack like a raisin's skin.

Like Earth, Mercury's outer core is composed of liquid metal, but there have only been hints that Mercury's innermost core is solid. Now, in a new study, scientists report evidence that Mercury's inner core is indeed solid and that it is very nearly the same size as Earth's solid inner core.

The camera system has been observing Mars from its primary science orbit since April 2018 and provides high-resolution, color images of the surface. On 2 March 2019, CaSSIS also delivered its first image of InSight, NASA's lander on Mars. Thu, 14 Mar 2019 12:31:57 EDT https://www.sciencedaily.com/releases/2019/03/190314123157.htm
