Wind-sculpted sand—that is how I think of dunes. In our main feature, “The Dune Whispers,” Ralph D. Lorenz describes the formation, and varieties, of these fascinating and beautiful works of planetary art.
The Mars Express team showcases some of the best viewing opportunities of Mars in 2014, including how to spot Comet Siding Spring when it flies past Mars this October.
At the Solander Point section of the rim of Endeavour Crater, Mars Exploration Rover Opportunity spent the month of March just off Murray Ridge working on its final targets in Cook Haven and dusting itself in the winds of winter, while MER mission officials on Earth were roving toward what may be the robot's current greatest potential threat – being cut from NASA's planetary science budget.
A video of Apollo astronaut David Scott's lecture to the Lunar and Planetary Science Conference. His talk was an absolute treat: funny, educational, engaging, full of joy at his adventure, though at the end, a little angry that we've not sent more humans back. It's well worth 45 minutes of your time.
NASA's LADEE Spacecraft to Fly Through an Eclipse, Crash into the Lunar Surface on April 21st
It's end-game for NASA's latest lunar mission
LADEE, NASA's latest robotic lunar spacecraft, will reach its planned end-of-mission on April 21st, when it will crash on the far side of the Moon.
Earlier this week, NASA announced that it was cutting off ties with Russia, except for activities relating to the ISS. This raised questions about Russian participation on NASA's science missions, particularly the Russian experiment on the Curiosity rover.

A Mars Reconnaissance Orbiter HiRISE image taken on February 10 shows Curiosity having just made deep, dark tracks across the Dingo Gap dune.
In December, scientists announced the discovery of possible plumes of water being ejected from Jupiters’s moon Europa. If confirmed, Europa would be the second moon with confirmed plumes after Saturn’s moon Enceladus. Two Discovery mission proposals for Enceladus suggest the types of missions that may be proposed for Europa.
On the heels of last weeks reports of a second Sedna and a ringed Centaur comes a third cool outer solar system discovery: A new, likely large member of the Kuiper belt. With an absolute magnitude of about 3.0, the new object currently known as 2013 FY27 is the tenth brightest object beyond Neptune .
She’s alive! She’s alive! Or is she? A little more than a week ago, at the Lunar and Planetary Science Conference 2014, evidence was presented that Venus was geologically active, not in the recent past, like 100,000 years ago, but right now.

Hubble has taken some great new images of our 'friend,' Comet Siding Spring, due to pass by Mars at less than 136,000 km on October 19 – less than half the distance between Earth and our moon.
A panel of three former astronauts will discuss the future of human spaceflight at a public event at the California Institute of Technology's Beckman Auditorium, Tuesday, April 8th, 2014 at 8 pm.
Some arm faults caused delays on Curiosity's approach to Kimberley, but the rover is now parked at its north edge, examining the "striated unit" up close with arm-mounted instruments.
