Mars used to have oceans, lakes, and rivers. Where did the water go, how much is left, and how can we use it for science and exploration?
The robotic explorers of our Cosmos are truly impressive, as showcased by several spacecraft this week.
See images your eyes wouldn’t normally be able to see, and learn about what these images can teach you.
A comet, an eclipse, a meteor shower, and planets... all are amazing reasons to look up at the night skies.
This week we take a look at some of the amazing Mars exploration being conducted, and celebrate the highlights of space in 2021.
China’s Zhurong Mars rover snaps a selfie and gets a bird’s-eye-view pic from above, and asteroid hunters of all kinds look out for dangerous rocks.
The Red Planet once had liquid water on the surface, and conditions that could have supported life.
We’re gearing up for a Mars landing, and our chief advocate takes a look at crewed Moon programs past and future.
Get an update on the latest in space exploration, and find out how you can help defend the Earth from asteroid impacts.
Blurred images and battery issues are no longer an immediate problem.
Mars Reconnaissance Orbiter has finally spotted the InSight lander, its parachute, and its heat shield resting on the Martian surface. The images confirm the location of InSight's landing site, a little to the north and west of the center of the landing ellipse. The lander is located at 4.499897° N, 135.616000° E.
Heedless of the (now-dissipating) dust storm, Curiosity has achieved its first successful drill into rocks that form the Vera Rubin ridge, and is hopefully on the way to a second. It took three attempts for Curiosity to find a soft enough spot, with Voyageurs and Ailsa Craig being too tough, but Stoer proved obligingly soft on sol 2136.
Mars today is a dynamic place. One visually dramatic sign of change on Mars is
NASA has announced changes to how engineers are operating Mars Reconnaissance Orbiter in order to prolong its life as long as possible, long enough to support the Mars 2020 rover mission.
The latest and greatest update of Emily's list of all the Mars Reconnaissance Orbiter HiRISE images that contain Curiosity hardware, tracks, or traverses.
Three years ago, on October 19, 2014, comet C/2013 A1 Siding Spring passed within 138,000 kilometers of Mars. At the 2017 meeting of the Division for Planetary Sciences of the American Astronomical Society, we heard a progress report on Mars orbiter imaging of the comet's nucleus.
The House of Representatives proposed $2.1 billion for NASA's planetary science budget, which would be an all-time high. Part of the increase would be used to start work on a new reconnaissance and communications orbiter.
Amateur space image processor Kevin Gill shares some of his stunning 3D images of Mars, created from real spacecraft data.
ESA issued an update on the Schiaparelli landing investigation today, identifying a problem reading from an inertial measurement unit as the proximate cause of the crash. Meanwhile, ExoMars Trace Gas Orbiter is operating its science instruments for the first time this week, and HiRISE has released calibrated versions of the Schiaparelli crash site images.
Martian radar expert Cassie Stuurman explains how the SHARAD instrument aboard NASA's Mars Reconnaissance Orbiter was used to detect buried ice deposits.
