The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.

Curiosity looked up after dark and captured more cool photos of Mars' moons. They include Phobos and Deimos passing in the night, and Phobos entering Mars' shadow.

Pay attention! This Mars orbiter, headed for launch in November, is a terrific science mission, as Mat Kaplan learned in a recent workshop, and in this week's Planetary Radio.

Take a spin around the Red Planet with the trusty orbiter.

Was there rainfall on Mars? Recent work mapping valley networks suggests there probably was -- but only for about 200 million years. What does this mean for life, and the Curiosity mission?

From sols 373 to 383 (August 23 to September 3, 2013), Curiosity traveled about 250 meters toward Mount Sharp over five drives, trying out her new AutoNav capability.

There wasn't a dull moment for the Mars Exploration Rover mission in August as Opportunity drove up to the base of the Solander Point section Endeavour Crater's eroded rim, crossed over a geological boundary between ancient eras, maneuvered through a boulder field, scooting unscathed from a near-miss with a rock that could have ended it all, and at month's end delivered her team to what looks to be another scientific gemstone on the Red Planet.

An interview with Bruce Murray from 2001 about his perspectives on Mars science and exploration: past, present, and future.

Bruce Murray was an early advocate for the inclusion of cameras on planetary spacecraft. As a tribute to him, I thought I'd take a look at a few of the images from the early Mariner missions to Mars.

Those sneaky scientists on Curiosity managed to catch a Phobos transit of the Sun with one set of cameras, and to watch its shadow darkening the surface with another. COOL!

Opportunity arrived at the base of the next segment of the Endeavour crater rim and is now investigating the contact.

Observations made by the Mars Climate Sounder, an instrument aboard NASA’s Mars Reconnaissance Orbiter, have revealed new information about atmospheric tides on the Red Planet.

It seems like it was just yesterday that 2000 people gathered in the Pasadena Convention Center to celebrate Curiosity's landing on Mars. All of Planetfest 2012 is online for your enjoyment.

This week Opportunity finished up a quick investigation of the strange rocky terrain out here in the plains where it is approaching the next mountain rim segment of Endeavour crater, Solander Point.

Kat Scanlon tells Planetary Radio that Hawaii and Mars have more in common than you might think.

The Mars Exploration Rovers (MER) mission Opportunity celebrated the 10th anniversary of its launch on July 7, 2003, and then went on to complete the last leg of its 2 km trek from Cape York to Solander Point. But just before the robot field geologist pulled onto the actual base of the ridge where it will spend its sixth Martian winter, Mars lured the team off the path with some of the weirdest Martian rocks the scientists have seen yet.
