Nine years ago today, Dawn set sail on an epic journey of discovery and adventure. The intrepid explorer has sailed the cosmic seas and collected treasures that far exceeded anything anticipated or even hoped for.
How far have we come and how far do we still need to go to welcome women into planetary science, and, particularly, spacecraft missions?

Opportunity got in the groove at Endeavour Crater in August finishing the last of her science assignments in Marathon Valley.
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.
Several readers have contacted me recently about reports that a group of international astronomers have detected a strong signal coming from a distant star that could be a sign of a high-technology civilization. Here’s my reaction: it’s interesting, but it’s definitely not the sign of an alien civilization—at least not yet.
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’s managers have begun the process for a competition to select a new planetary mission to launch in the mid-2020s that will address one of the most important questions in planetary science.
What began as a tantalizing rumor has just become an astonishing fact. Today a group of thirty-one scientists announced the discovery of a terrestrial exoplanet orbiting Proxima Centauri. The discovery of this planet, Proxima Centauri b, is a huge breakthrough not just for astronomers but for all of us. Here’s why.
Martian gullies were in the spotlight last week thanks to a NASA press release stating they were "likely not formed by liquid water" based on spectral results. But how does this stack up against their morphology?
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.

We know, as well as you do, that if we want to see a great future – one where humans explore, understand, and benefit from space – we need to invest right now in the people who will be leading the way. To empower the world’s youth, we need to educate them. And to educate them, we need to inspire them.
Despite the intensifying rancor and ugliness of the U.S. Presidential campaigns on Earth, as the spring Sun shined down on Meridiani Planum in July, all was right with the world at Endeavour Crater.

Selecting a theme for our reinvented membership experience involved hundreds of people from staff to members. Here's the process that created the names for the new membership levels.
The MAVEN mission to Mars was just approved for a two-year extended mission that runs through September 2018. Now is a good time to take stock of we've learned so far and to describe the plans for the extended mission.
Today we launch a new expedition to engage our members in more ways than ever before. Since our inception, our members have supported The Planetary Society as we forge new paths in space science and exploration. You have always been at the center of our success and we want the structure of our membership program to reflect that by offering new benefits, premiums and payment options.

Science in America depends on federal funding, yet many young scientists don't understand how the U.S. government decides to spend its money on science, nor are they encouraged to use their new degrees to advise the process. This is changing with support from the American Association for the Advancement of Science.

Opportunity spent the first half of May digging into an outcrop, taking dozens of panoramic images from her site on the south wall of Marathon Valley at Endeavour Crater’s western rim, and basking in the Martian spring weather.
A difficult but necessary decision by ESA and Roskosmos to postpone the launch of the ExoMars rover from 2018 to 2020 raises a question about the fate of other planetary exploration programs in the pipelines of both space agencies.
Looking back at Earth from beyond helps to give perspective on our place in the cosmos.
Opportunity and the Mars Exploration Rovers (MER) team pressed on through the Martian winter and spent April sleuthing for clay minerals at the mission’s new site on the southern wall of Marathon Valley.
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.
HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.
Why does our planet look the way it does from space? How does light interacting with land, clouds, water, snow, ice, gases, and various aerosols all come together? One way to learn the answer is to try and synthesize DSCOVR's view from various "building blocks" of geophysical and atmospheric data.
Until just a few years ago, a plot of mass versus size of other worlds would have looked pretty sparse and uninformative. But thanks to the tireless efforts of exoplanet astronomers, we now know fairly precise masses and radii for hundreds of distant worlds.
There was no shortage of interesting lunar science talks at last month’s Lunar and Planetary Science Conference. Dr. Ryan Clegg-Watkins highlights some of the interesting results for us.
At a recent meeting of an advisory group for NASA, the Committee on Astrobiology and Planetary Science (CAPS), Jim Green, the head of NASA’s Planetary Science Division, and Barry Goldstein from the Jet Propulsion Laboratory, provided updates on plans to explore our solar system's ocean worlds.
This year's Lunar and Planetary Science Conference included a session devoted to a group of rocks from space called differentiated meteorites, and their proposed parent bodies.
Huygens may have landed on Titan over a decade ago, but a group of researchers from York University were able to make a new and unexpected discovery with this older dataset.
As March Madness on Earth sent sports fans into their annual kinetic frenzy watching more than 60 American teams battle it out for college basketball’s grandest title, Opportunity was experiencing her own Martian brand of March Madness.
One year after taking up its new residence in the solar system, Dawn is continuing to witness extraordinary sights on dwarf planet Ceres. Mission Director Marc Rayman brings us his monthly update on Dawn's status.
This past week brought to the fore two challenges for NASA’s managers as they try to enable the richest possible mix of coming planetary missions. At stake are whether the agency will be able to select two Discovery missions from the current competition, and whether there will be the possibility of a mission selected for Enceladus and/or Titan in the next decade.
Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.
As the Martian winter slowly begins to recede, Opportunity is working away on the steep slopes of Knudsen Ridge at the southern end of Marathon Valley, showing her mettle in some of the most challenging terrain of the rover’s 12+ years on the Red Planet.
MENCA (Mars Exospheric Neutral Composition Analyser) is a quadrupole mass spectrometer onboard India's Mars Orbiter Mission, MOM. A report on measurements of neutral species accepted for publication in Geophysical Research Letters is the first peer-reviewed scientific result from the mission.
Cosmologist Jason Rhodes details the path he took to play a leading role in a European mission designed to learn about dark energy.
More than eight years after leaving Earth behind for an ambitious deep space adventure, the Dawn mission has now collected all of the data originally planned. Chief Engineer and Mission Director Marc Rayman brings us an update.
NASA's New Budget Would Gut Europa But Otherwise Support Planetary Exploration
All these worlds are yours, except for...
It’s clear that the President’s budget officers really don’t want to fund a mission to Europa. Other than that, the proposed Fiscal Year 2017 budget submitted by the President last week to Congress would be great for planetary exploration.
