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.

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.
As she did before for Curiosity, Emily Lakdawalla has searched through the HiRISE image archive for photos of the Opportunity landing site and sorted them all out so that you don't have to.
Following up the detection of the Schiaparelli crash site by Mars Reconnaissance Orbiter CTX, the higher-resolution HiRISE camera has now definitively identified the locations of lander impact site, parachute with backshell, and heat shield impact site on the Martian surface.
Just a day after the arrival of ExoMars Trace Gas Orbiter and its lander Schiaparelli, Mars Reconnaissance Orbiter has taken a photo of the landing site with its Context Camera, and things do not look good.
Martian gullies were in the spotlight last week thanks to a NASA press release stating they were
Opportunity arrived at its current location on sol 4345 to begin investigation of an outcrop on the crest of a ridge near the west end of Marathon Valley.
HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.
