The Planetary Society

Six scientists share the major planetary science discoveries of the past decade, and the questions that will drive the next 10 years of solar system exploration.

A new issue of The Planetary Report brings you our pride in the success of LightSail 2 and our gratitude to our members for making it happen. Plus Venus science from Akatsuki and Venus Express, and the status of planetary defense.

Javier Peralta

Javier Peralta plumbs the depths of Venus’ atmosphere through the eyes of the Venus Express and Akatsuki orbiters.

BepiColombo's launch was nominal -- the best thing any launch can be. Following launch, the spacecraft documented successful solar array and antenna deployments with self-portraits.

I’m thrilled to be anticipating the beginning of a new mission to Mercury. Here's a timeline for BepiColombo's planned launch on 20 October (19 October in the U.S.).

Elsa Montagnon details the challenges of delivering BepiColombo’s two spacecraft from Earth to Mercury.

With my first issue of The Planetary Report as editor, I am taking the magazine open-access. Return to Mercury features articles by Elsa Montagnon on BepiColombo and by Long Xiao on the Chang'e-4 and -5 landers.

A Mercury meeting held May 1-3 summarized the current and future science of the innermost planet. Emily Lakdawalla was there and shares her notes.

Three launches to the Moon and one each to Mercury and Mars; two arrivals at near-Earth asteroids; and an approach to an encounter with a distant Kuiper belt object are highlights we anticipate in 2018.

Next year, a pair of probes head to Mercury to answer outstanding questions about our innermost planet, as well as the formation of the solar system.

2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.

This month we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress toward its September 8 launch. Both rovers are road-tripping at Mars, while ExoMars Trace Gas Orbiter has completed a major mid-course correction ahead of its October arrival.

Japan's Akatsuki Venus orbiter is well into its science mission, and has already produced surprising science results. The mission, originally planned to last two years, could last as many as five, monitoring Venus' atmosphere over the long term.

May 2016 will be yet another month of fairly routine operations across the solar system -- if you can ever use the word

There are two types of atmospheric waves that are critically important on Earth and other planets: gravity waves and planetary waves.

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.

JAXA had a press briefing today to confirm the successful arrival of Akatsuki into Venus orbit. It's been a long time coming: today's announcement came twelve years to the day after Japan had to abandon efforts to put Nozomi into Mars orbit. They released lovely images and discussed future plans.

Sanjay Limaye

One day after closest approach, Akatsuki is now speeding away from Venus at 4.09 kilometers per second and is 180,000 kilometers from the planet. In his last report from Sagamihara, Sanjay Limaye gets some updates on the new orbiter's trajectory.
