Arabia Terra has always been a bit of a martian enigma. Planetary scientist Joel Davis takes us on a tour of its valley networks and their significance in telling the story of water on Mars.
Earth possesses amazing biological diversity. Every corner of this planet—no matter how bizarre the place—is inhabited by microorganisms. This includes impact craters.

The current GOES-East and GOES-West have been faithfully providing continuous imagery and data on Earth and space weather for almost a decade. So, with the launch of the first of the next generation of GOES satellites, GOES-R, what is NOAA trying to accomplish?
Martian gullies were in the spotlight last week thanks to a NASA press release stating they were "likely not formed by liquid water" based on spectral results. But how does this stack up against their morphology?
Looking back at Earth from beyond helps to give perspective on our place in the cosmos.
Why does our planet look the way it does from space? How does light interacting with land, clouds, water, snow, ice, gases, and various aerosols all come together? One way to learn the answer is to try and synthesize DSCOVR's view from various "building blocks" of geophysical and atmospheric data.
Inspired by the Mars Webcam on Mars Express, ESA's Cluster mission has turned on a camera on the Cluster spacecraft for the first time since their launch more than 15 years ago. UPDATE: It has now acquired images of Earth.
Two images of Earth taken from different spacecraft at the same time illustrate differences in "true" color imaging among spacecraft.
It's fun to watch the seasons shift from space, and as of this year we have new ways to do that.
I just love photos of Earth from planetary missions -- especially if they manage to get Earth and Moon in the same shot, as Hayabusa2 did on November 26.

Akatsuki is finally approaching its second attempt to enter Venus orbit, on December 7; let's all wish JAXA the best of luck! And PROCYON, whose ion engines have failed, is still an otherwise perfectly functional spacecraft that is taking photos of Earth and the Moon as it approaches for a flyby.
