OSIRIS-REx is ready to begin its journey to Bennu and back. The asteroid was named by a Planetary Society contest winner, and the spacecraft bears the names of 440,000 well-wishers.

Ever since its landing, Philae has been elusive. It went silent just three days later and never returned any more science data, though it made brief contact with the orbiter last summer. Now, just a month until the planned end of the Rosetta mission, the orbiter has finally located the lander in a stunning high-resolution view of the surface.

On August 27, Juno soared across Jupiter's cloud tops from pole to pole, with all instruments operating. NASA posted some terrific first results from several of the instruments today. And the JunoCam team released all 28 raw images taken during the close encounter.

The OSIRIS-REx mission passed its flight readiness review yesterday, clearing the way for the spacecraft to launch on Thursday, September 8. Here's a schedule of next week's NASA TV briefings and a photo album of the launch preparations.

Following the conclusion of Dawn's ambitious 8.8-year prime mission on June 30, the spacecraft has been gathering a wealth of data with all sensors in its extended mission as it orbits closer to Ceres than the International Space Station is to Earth.

The month of September begins with an annular solar eclipse visible from much of Africa on September 1. On or after September 8, we'll see OSIRIS-REx launch into a two-year cruise toward a rendezvous with asteroid Bennu. But September will close, sadly, with the end of the wonderful Rosetta mission.

It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.

NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.

Whenever I share images from Curiosity, among the most common questions I’m asked is “what is the scale of this image?” With help from imaging enthusiast Seán Doran, I can answer that question for some of the Murray buttes.

Since a few days after entering orbit, JunoCam has been taking photos of Jupiter every fifteen minutes, accumulating a trove of data that can be assembled into a movie of the planet.

Launch day is coming for NASA's next interplanetary explorer! OSIRIS-REx is on schedule for launch on September 8, 2016 at 19:05 EDT (16:05 PDT, 23:05 UTC) from Cape Canaveral Air Force Station. OSIRIS-REx is the first NASA planetary launch since MAVEN in 2013, and will be the last until InSight in 2018.

Juno’s science goals are to understand the origin and interior of Jupiter, focusing specifically on its atmosphere and magnetic field. Cameras can help answer some of these questions.

Only 24 days remain until the opening of OSIRIS-REx's launch period, and final preparations are underway. There is a lot to do in the final months before a launch, but things seem to be going well.

Curiosity has now covered most of the flat ground that lay between the Naukluft plateau and the Murray buttes. The mission took only 11 days to complete drilling work at Marimba, despite a recurrence of a problematic short in the drill. The rover is ready to drive in among the buttes, shooting spectacular photos along the way.

Despite what you may have read on other websites last week, China's Yutu lunar rover is probably still functional on the surface of the Moon.

NASA’s next big “flagship” astronomy mission, following the ambitious James Webb Space Telescope due to be launched in 2018, is currently known as the Wide Field Infrared Survey Telescope (WFIRST)—but it's had a slew of different names.
