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.

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.

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.

ESA's comet-chasing Rosetta spacecraft is nearing the end of its mission. Last week, ESA announced when and where Rosetta is going to touch down. And tomorrow, it will forever shut down the radio system intended for communicating with the silent Philae lander.

Highlights this month include the impending arrival of Juno at Jupiter, the approval of extended missions for all of NASA's solar system spacecraft, and public data releases from Rosetta, New Horizons, and Cassini.

OSIRIS-REx's long journey to an asteroid has begun. The spacecraft departed Colorado on Friday, May 20, travelling aboard an Air Force C-17 to the Payload Hazardous Servicing Facility at Kennedy Space Center.

Last week, the Rosetta mission released a large quantity of science data to the worldwide public, including photos from the mission's close observation phase and the Philae landing.

Since April 11, instead of photographing the scenery directly beneath it, Dawn has been aiming its camera to the left and forward as it orbits and Ceres rotates to map more of the dwarf planet.

This month (actually, today), Cassini had a relatively close flyby of Titan, and New Horizons will observe a very distant Kuiper belt object named 1994 JR1. Akatsuki has just fine-tuned its orbit around Venus, and Hayabusa2 has begun an 800-hour ion engine thrusting phase to steer it toward near-Earth asteroid Ryugu.

Welcome to my monthly inventory of the 20-plus spacecraft actively exploring our solar system. Highlights of this month include the impending launch of the ExoMars Trace Gas Orbiter and Schiaparelli lander, currently planned for March 14, and the resumption of regular VMC Mars images by Mars Express.
