The Mars Reconnaissance Orbiter has just begun its science mission, and one of the first targets is Victoria Crater, where the rover Opportunity has just arrived after nearly 1000 sols on Mars.

The photos, using the largest interplanetary telescope ever lofted, are truly amazing.

The most productive and longest-lived mission to Mars has likely ended, NASA says. For nearly ten years, the orbiter mapped the surface of Mars, and it played a big role in selecting the landing sites for the successful Mars Rover missions. A problem with a solar panel joint led to its demise. picked by Fanatic 2 years ago

Days before its tenth anniversary in Mars orbit, the Mars Global Surveyor spacecraft ran into problems. They got a weak signal three days later, and nothing since. Plans are to take a photograph of it with another Mars Orbiter today or tomorrow. picked by Fanatic 2 years ago

NASA scientists have discovered what might form some of the weirdest landscapes on Mars, winding channels carved into the Martian surface that scientists have dubbed "spiders," "lace" and "lizard skin." The unusual landscape features form in an area of Mars' south pole called cryptic terrain because it once defied explanation. More pictures picked by AutumnLotus 9 months ago

New research raises the possibility that Mars could awaken from within -- three large Martian volcanoes may only be dormant, not extinct. Volcanic eruptions release lots of greenhouse gasses, like carbon dioxide, into the atmosphere. If the eruptions are not complete, and future eruptions are large enough, they could warm the Martian climate from its present extremely cold and dry state. picked by AutumnLotus 11 months ago

A probable active glacier has been identified for the first time on Mars. The icy feature has been spotted in images from the European Space Agency's (Esa) Mars Express spacecraft. Ancient glaciers, many millions of years old, have been seen before on the Red Planet, but this one may only be several thousand years old. picked by AutumnLotus 9 months ago

Mars was covered in an ocean of molten rock for about 100 million years after the planet formed, researchers found. The formation of the solar system can be dated quite accurately to 4,567,000,000 years ago. Mars' metallic core formed a few million years after that. Previous estimates for how long the surface remained molten ranged from thousands of years to several hundred million years picked by AutumnLotus 9 months ago

The longstanding mystery of how oceans once formed on Mars could be solved by fire and brimstone. Specifically, researchers now suggest that ancient volcanoes could have released brimstone — now more commonly known as sulfur — that warmed up the red planet enough for liquid water oceans in the early days of Mars. These findings might also shed insight on the young Earth, including the ... read full post picked by AutumnLotus 9 months ago

These two images taken by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) show Mars' two small moons, Phobos and Deimos, as seen from the Mars Reconnaissance Orbiter's low orbit around Mars. Both images were taken while the spacecraft was over Mars' night side, with the spacecraft turned off its normal nadir-viewing geometry to glimpse the moons. picked by AutumnLotus 9 months ago

What it would be like to fly over Mars? Combining terrain data from the orbiting Mars Reconnaissance Orbiter spacecraft with information about the robotic Spirit rover currently rolling across Mars has resulted in a digital movie that shows what a flight over the Columbia Hills might look like. picked by sandossu 4 months ago

A lake that might once have been habitable may have filled a crater for a long time on early Mars, new spacecraft images reveal. NASA's Mars Reconnaissance Orbiter captured the images that suggest the debris-strewn Holden Crater once held a calm body of water that could have harbored life. picked by AutumnLotus 6 months ago

The radar system on the European Space Agency's Mars Express orbiter has uncovered new details about some of the most mysterious deposits on Mars: the Medusae Fossae Formation. It has provided the first direct measurement of the depth and electrical properties of these materials, providing new clues about their origin. picked by AutumnLotus 10 months ago

If skies are clear in your area on Sunday night, Dec. 23, you'll be able to partake in a rather unusual sight as the full moon appears to glide very closely above the planet Mars. Mars, which made its closest approach to the Earth on Dec. 18, will be only hours from a Christmas Eve opposition with the sun and is now shining prominently with a bright yellow-orange glow. picked by AutumnLotus 9 months ago

Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impac... read full post picked by AutumnLotus 9 months ago

For the first time, satellite imagery reveals thick Martian salt deposits scattered across the planet's southern surface, which one planetary scientist claims could be sites of ancient life. The mats of sodium chloride — the same taste-enhancing mineral found on your kitchen table — serve as more evidence of Mars' watery past, and researchers think the briney pools that made them could... read full post picked by AutumnLotus 6 months ago
