In Kentucky, some very driven people are writing their own chapter of space exploration based on vision, entrepreneurial risk, and scientific and engineering know-how. Wayne Hall shares their stories.
Planetary astronomer Mark Showalter tells the story of when he became the first human to ever set eyes on Saturn's strange moon Pan in 1990.
For nearly two years, Opportunity's world has been tilted 10–25 degrees as it drove down to the lower slopes of the wall of Endeavour Crater. Toward the end of last week, Opportunity pulled itself up and over the lip of the crater.
Driving the Mars Exploration Rovers (MER) mission further into its fourteenth year of surface operations, Opportunity continued hiking the slopes of Cape Tribulation in February and finally reached the crest of Endeavour Crater’s western rim.
Citizen scientist and self-described "comet whisperer" Marco Parisi explains how he made a striking discovery on Comet 67P using Rosetta mission data.
Scientists have found seven, Earth-size planets orbiting a star just 40 light years away. Three lie in the habitable zone and could have water on their surfaces.
Amateur image processor Ted Stryk revisited Voyager 1 data of Enceladus and came across a surprise.

Opportunity has successfully clawed its way to within a few meters of the crater rim after spending the last few months climbing and the last two years inside the crater.
The Science Line—a non-profit working to bridge the gap between science, technology and fashion by inspiring youth through STEM fashion shows, competitions, educational kits and hands-on workshops—hosted the first STEM Fashion Show in partnership with the Challenger Space Center of Arizona.

Several sols ago, Opportunity made it up and past the steepest section of its climb out of Endeavour crater.
Earth possesses amazing biological diversity. Every corner of this planet—no matter how bizarre the place—is inhabited by microorganisms. This includes impact craters.
2017 got off to a start that was unprecedented in every good way: Opportunity completed her 13th Earth year of surface operations and drove the first overland expedition of the Red Planet into its 14th year.
Russia’s Proton rocket grounded by poor quality control
More woes for the country's launch fleet
Russia's workhorse Proton rocket may be grounded until June or July, dealing another blow to the country's launch infrastructure, which has been plagued by brain drain, mismanagement, poor quality control and corruption.
Amateur space image processor Kevin Gill shares some of his stunning 3D images of Mars, created from real spacecraft data.
Blitzing Congress for NASA
Or, How I Spent My Day Off in DC

Last February, a group called the Space Exploration Alliance held their annual "legislative blitz," walking the halls of Congress to sway lawmakers toward increased support for NASA's 2017 budget.
More than a month after a Progress spacecraft bound for the International Space Station plunged to the ground during a botched launch attempt, investigators are still unable to clear its rocket to carry future ISS crews.

As 2016 came to an end and 2017 rang in, Opportunity was working the first leg of the ascent up the rugged western rim of Endeavour Crater on her way to an ancient gully, the next scientific tour de force down the road, and the mission was closing in on its 13th anniversary of surface operations coming up in the New Year.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
