Telerobotics—with humans nearby—just might be the perfect unification of human and robotic spaceflight. Two groups at NASA and ESA are working to make this fledgling technology commonplace.

With some help from astronomer Elizabeth Tasker and a group of astronomy graduate students from the University of Hokkaido, I learn how.

A couple of weeks ago, there was a flurry of rumor that ISRO was ready to announce some results from its Mars Orbiter Mission's methane sensor. The Indian space agency held a press event for the one-year-in-orbit anniversary of Mars Orbiter Mission and released a book containing mission photos, but did not unveil any new scientific results.

JAXA announced today the results of the naming contest for Hayabusa2. The target of the sample-return mission, formerly known as 1999 JU3 and still numbered 162173, is now named 162173 Ryugu.

Now that New Horizons is regularly sending back data, the mission is settling into a routine of releasing a set of captioned images on Thursdays, followed by raw LORRI images on Friday. The Thursday releases give us the opportunity to see lovely color data from the spacecraft's Ralph MVIC instrument. This week, the newly available color data set covered Charon.

Opportunity continued her walkabout around Marathon Valley in September and sent home more evidence of significant water alteration and, perhaps, an ancient environment inviting enough for the emergence of life.

This is the first in a series of posts in which scientists share favorite planetary science plots. For my #FaveAstroPlot, I explain what you can see when you look at how asteroid orbit eccentricity and inclination vary with distance from the Sun.

NASA announced the first-round selections for its next Discovery mission today. A total of five planetary mission concepts -- three targeted at asteroids, two at Venus -- will move to the next stage of the competition.

Last Friday I posted an image containing 18 samples of terrain, all shown at the same scale. Were you able to figure out which square was which? Here are the answers.

Learn all about a sustainable, affordable path to get humans to the Red Planet—a path that goes through Mars orbit and Phobos.

NASA held a press briefing today to publicize a cool incremental result in the story of present-day liquid water on Mars. How big a deal is this story? Was all the pre-announcement hype justified? Is this just NASA discovering water on Mars for the zillionth time? What does this mean for things many space fans care about: life on Mars or future human exploration?

On the 8th anniversary of the launch of the Dawn spacecraft, Chief Engineer and Mission Director Marc Rayman gives his annual summary of Dawn’s progress on its interplanetary travels.

Trying to keep track of the ever-changing face of Jupiter is a pretty big challenge—its a dynamic world that can fascinate and surprise every time we turn our telescopes towards it.

There are no spacecraft at Uranus or Neptune, and there haven't been for 30 and 25 years, respectively. So we depend on Earth-based astronomers to monitor them, including Damian Peach.
