After a pause of about a week in daily image releases from Rosetta, ESA has begun sharing four-image sets of photos of comet Churyumov-Gerasimenko and invited the public to help produce pretty pictures from them.
The excitement is building for Hayabusa 2! The spacecraft is now complete and ready to be shipped to its launch site. JAXA unveiled its next interplanetary traveler to the media in a special event on August 31.
Karl Battams highlights the historic discovery, by an Air Force satellite, of a sungrazing comet.
The Rise and Fall (and Rise and Fall) of Planetary Exploration Funding
NASA has explored the planets since the 1960s, but funding has rarely been consistent
NASA has explored the solar system since the 1960s, but it has rarely been the top priority for the space agency. Jason Callahan breaks down how planetary science has been funded over the years within NASA's larger budget.

Planetary Society OSETI Going Strong

The Planetary Society sponsored all-sky optical SETI search at Harvard University went off the rails, telescope roof rails that is, but it is back on track and hunting the sky for ET.
NASA’s Big Rocket a Step Closer to Reality
The Space Launch System has been approved for production
NASA's Space Launch System passed a critical milestone yesterday, but buried within the announcement was news that the first launch could slip by nearly a year.

The Competition for Dollars
What is NASA's main competition for funding within the federal budget? It's not what you think.
We all know NASA needs more money to achieve its goals. But competition for money is intense within the U.S. federal government, and two trends have made it harder for NASA to get what it needs.
The Rosetta team has announced the selection of five regions on Churyumov-Gerasimenko that they will study as possible landing sites for little Philae. Now, as Rosetta surveys the comet from its second triangular "orbit" at an average distance of 60 kilometers, the mission will target these spots for extra attention.
Shooting video of a lumpy moon crossing the Sun and turning it into a giant googly eye is not a new activity for Curiosity, but I get a fresh thrill each time I see one of these sequences downlinked from the rover.
In honor of the 25th anniversary of the Voyager 2 flyby of Neptune, image magician Björn Jónsson has produced two new global mosaics of the distant ice giant, the highest-resolution ever made.
A pesky radio problem that has occasionally stymied LightSail has returned, scrubbing the mission's day-in-the-life test.
The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.
Rosetta spent the week transitioning to a lower orbit from which it continues to observe the comet. This weekend, the mission will select about five landing sites for more detailed study. They have also now estimated the mass of the comet.
