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. Find out what they could tell us about watery ancient Mars versus the dry Red Planet we see today.

A new immersive, 360-degree, ultra-high-definition visualization allows viewers to view the center of our Galaxy as if they were sitting in the position of the Milky Way’s supermassive black hole (Sgr A*). By combining supercomputer simulations with Chandra data, the visualization shows the effects of dozens of massive stellar giants with fierce winds blowing off their surfaces in the region covering a few light years surrounding Sgr A*.

Blue and cyan represent X-ray emission from hot gas with temperatures of tens of millions of degrees, while the red emission shows ultraviolet emission from moderately dense regions of cooler gas with temperatures of tens of thousands of degrees, and yellow shows the cooler gas with the highest densities.

FACET – short for Future Air Traffic Management Concepts Evaluation Tool –was such a hit when it was introduced a decade ago that NASA named it the agency’s Software of the Year for 2006. As a research tool, FACET quickly analyzes thousands of aircraft paths and displays them on a map. One of FACET’s new features is to display global flight trajectories between the continents. NASA receives data from the Official Airline Guide, which provides the departure and arrival cities, and the expected departure and arrival times.

FACET then draws a Great Circle route between the city pairs and calculates where the aircraft would be at any given time. NASA has used this capability to study the impact of global aviation emissions on the environment.
