It's fun to watch the seasons shift from space, and as of this year we have new ways to do that.

The Planetary Deep Drill is being tested in a California gypsum mine. Several Planetary Society staff took a road trip to visit the ongoing Honeybee Robotics test of this prototype robotic drill that could one day drill hundreds of meters into planetary ices.

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.

The third entry in my series of blog posts about Favorite Astro Plots contains one of the biggest discoveries from the Apollo program -- as well as one of the biggest questions in planetary science. The chart was nominated by planetary scientist Barbara Cohen. It has to do with the ages of surfaces on the Moon.

A project to digitize more than 90,000 images taken by NASA’s five Surveyor spacecraft in the 1960s has revealed early hints of never-before-seen treasures captured by America’s first robotic lunar landers.

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.

On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.

Ralph Lorenz

Planetary scientist Ralph Lorenz briefs us on the current state of our knowledge on dust devils on Earth and Mars.

Three recently proposed low-cost space missions all aim to answer the same question: Where did Earth's abundant water come from?

Phil Stooke

Planetary scientist Phil Stooke may have found the retro-rockets from NASA's Lunar Surveyor missions, sent to the Moon in preparation for Apollo.

This summer the Chinese space agency has been making progress toward its planned 2017 launch of the Chang'e 5 robotic sample return mission, performing low-altitude imaging of the future landing site.

Casey Dreier

Casey interviews Dr. Craig Hardgrove about his lunar CubeSat, how it came together, and how NASA’s support for small missions are important for early career scientists like himself.

Students gather in the desert to answer the University Rover Challenge, pushing the limits of the tech that will drive future Mars exploration.

The Deep Space Climate Observatory (DSCOVR) has begun sending us fresh, whole-hemisphere images of our own fragile planet. Some sources say that the spacecraft is

Five months after its launch, the Deep Space Climate Observatory (DSCOVR) mission has successfully journeyed to the region of space where Sun and Earth gravitational attraction offset each other. From the vantage point of L1, DSCOVR's EPIC camera has captured its first full-globe view of Earth, and it's well, epic.

The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.

Three astronauts have returned to Earth, and while I'm happy that they landed safely, I'm very sad that astronaut Samantha Cristoforetti is not in space anymore to wish us
