It's here! 5.7 trillion pixels of Mars from the amazing CTX camera in your web browser, or available for download. Everything you need is here: murray-lab.caltech.edu/CTX/. The whole planet in one image at high-resolution.

‘Our study addresses whether Mars was able to achieve the absolute minimum conditions for liquid water at gully locations,’ says @ErroneousTholus. ‘We hope it inspires researchers to take an even closer look at this topic.’ chemistryworld.com/news/liquid-wa…

@tanyaofmars Mars will eventually go back to being able to carve new gullies with liquid water, in thousands of years. Until then, Mars will be dominated by CO2, which will continue to modify gullies, as we can see from orbit today. 6/6

@tanyaofmars We argue that Mars has been capable of producing enough liquid water to carve channels within the last million years, far more recent than billions of years ago when Mars had huge rivers, lakes and maybe an ocean. 5/x

New Mars paper this week in @ScienceMagazine. For over two decades, landforms on Mars called gullies have presented a problem: how can these recent features that closely resemble water-carved channels on Earth form on a planet so cold and with such a thin atmosphere?
Keith Smith@DrKeithSmith

Gullies on #Mars formed by liquid flowing on the surface, but none is expected in the current climate. James Dickson (@ErroneousTholus) et al. show the distribution of gullies is consistent with simulated locations of liquid water >600,000 years ago. science.org/doi/10.1126/sc…

There are still a few things to tweak but the first version of CTX Mosaic-based DTM search is now live at AreoBrowser.com! Click the map icon on the bottom bar whilst in terrain mode to show/hide the map 🛰️⛰️ #Mars #Space

How far we've come in the last 50 years! Back in 1972, a team at JPL spent days pasting together photographs taken by Mariner 9 by hand to create a 4-foot globe of Mars. nasa.gov/image-feature/…

Now you can explore Martian features like cliffsides + craters up close – from your web browser! @Caltech has created the highest resolution global image we've ever had of the Red Planet, using images from @NASA's Mars Reconnaissance Orbiter. Learn more: go.nasa.gov/3UazHrD

Jay Dickson @ErroneousTholus, planétologue au Murray Lab, a réalisé une carte de la planète Mars composée de *110 000* images prises par la caméra CTX 🤯 Elle offre la possibilité d’explorer les paysages accidentés martiens avec une multitude de détails.

Major thanks to our colleagues @Esri and @ASU with the @jmars_gis team for working incredibly hard to get this massive image processed for scientists to use right away. See the very simple instructions under "Access the Data" at the link above.
