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 "orbiting" the L1 point. Dave Doody thinks this warrants some scrutiny.
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.
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 "buona notte dallo spazio" with her lovely photos and piquant comments.

Our own Dr. Bruce Betts is once again teaching his Introduction to Planetary Science and Astronomy college course online. Come join him.
Watch as our enormous moon -- a quarter the diameter of the planet -- just winks out as it passes into Earth's long shadow, in an animation captured from more than 100 million kilometers away.
Have you ever wished you could enjoy the astronauts' view of Earth from the Space Station? Now, you can. Just go to the live feed from the High Definition Earth Viewing (HDEV) experiment, crank it up to its highest resolution, let it take over your monitor, and watch Earth spin by.

Earth's brilliant colors shine above the drab lunar horizon in this new "Earthrise" photo from the Lunar Reconnaissance Orbiter. An animation that accompanied the image release helped me to write an explainer on how pushframe cameras like Lunar Reconnaissance Orbiter's Wide-Angle Camera works.
What can a 45-year-old mission to the Moon tell us about a "meteorite" flying past a skydiver on Earth?

This video of class 4 of Bruce Betts' Introduction to Planetary Science and Astronomy class discusses eclipses, Mercury, Venus, and a comparison of the atmospheres of Venus, Earth, and Mars.
A few days ago, Curiosity looked westward after sunset and photographed Earth setting toward the mountainous rim of Gale crater.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
