Less than a year from its rendezvous with dwarf planet Ceres, Dawn is continuing to make excellent progress on its ambitious interplanetary adventure. But once it gets to Ceres, just how will it go into orbit? Marc Rayman explains.
There is an asteroid threat and space debris workshop in Scotland this week that Planetary Society support helped lead to, and that will include two public lectures you can tune into live.
Earth and its solar system compatriots all have nearly circular orbits, but many exoplanets orbit their stars on wildly eccentric paths. Is our home system strange? Or is our sense of the data skewed?

The OSIRIS-REx Science Team gathered at the University of Arizona from April 22–24, 2014 for their sixth meeting. Principal Investigator Dante Lauretta discusses a few of the highlights.
An attempt to corral the discussion of the IAU planet definition in one place on planetary.org, so that we may be free to actually discuss Kuiper belt observations and scientific results on posts elsewhere on this site.
The Cassini mission has already returned an array of images of other solar system members from Saturn orbit: Earth (and the Moon), Venus, Mars, and Jupiter. It’s time to add another world to that list!

Learn about the formation and origin of the Solar System and go beyond our neighborhood to investigate exoplanets (planets around other stars) in this video of class 11 of Bruce Betts' Introduction to Planetary Science and Astronomy class.
After completing the initial reconnaissance of the Kimberley outcrop two weeks ago, Curiosity is, at last, moving toward a drill site. The science team selected the location last week: a spot near the base of Mount Remarkable, into what they have been calling the "middle unit" at the Kimberley.
LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.
