We frequently call the HiRISE camera on board the Mars Reconnaissance Orbiter “our favorite camera” and for good reason. HiRISE, the High Resolution Imaging Science Experiment, is the largest and most powerful camera ever flown on a planetary mission, sending back incredible beautiful, high-resolution images of Mars.
These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of […]
Mars today is a planet that appears to be mostly shaped by wind, but that wasn’t always the case. A new map adds information to the hypothesis that “marsquakes” affected at least a part of the planet’s vast canyon, Valles Marineris, while the area contained spring-filled lakes. When the damp sand got shaken up, it […]
Does liquid water currently flow on the surface of Mars? Fresh-looking trenches on the Red Planet have come under a lot of scrutiny, including a 2010 study concluding that 18 dune gullies were primarily formed by carbon dioxide freezing. A new study looking at several more gullies comes to about the same conclusion. Researchers examined […]
NASA has now released a breathtaking high resolution image of the rover Curiosity captured from Mars orbit coincidentally coinciding with her crossing the targeted landing ellipse just days after she marked ‘1 Martian Year’ on the Red Planet in search of the chemical ingredients necessary to support alien microbial life forms. The orbital image was […]
The great thing about the longevity of the Mars Reconnaissance Orbiter is that we can see changes taking place on the Red Planet, such as this relatively new and rather large impact crater. This image shows a stunning 30-meter-wide crater with a rayed blast zone and far-flung secondary material surrounding. Scientists say the impact and […]
Amazing, the things a birds-eye view allows you to see. Here’s a color image from the HiRISE camera on board the Mars Reconnaissance Orbiter showing the tracks of the Curiosity rover. In this most recent HiRISE image of the MSL rover, the tracks are visible from Yellowknife Bay to its location on 11 December 2013, […]
