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.

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 8 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 5 months ago

Fossil microbes found along an iron-rich river in Spain reveal how signs of life could be preserved in minerals found on Mars. The discovery may help to equip the next generation Mars rover with the tools it would need to find evidence of past life on the planet. picked by AutumnLotus 4 months ago

Spirit and Opportunity, the NASA Mars Rovers, have discovered interesting features that suggest Mars could have supported life at one time, including 'rivers' of frozen carbon dioxide that flow uphill. picked by tundramonkey 8 months ago

Water on Mars was once widespread and long-lasting, providing environments with the potential to support life, a new study finds. picked by AutumnLotus 1 month ago

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

Nasa is to launch a spacecraft on a nine-month journey to Mars, where it will dig below the surface for clues to the existence of past or present life. picked by pjanaway 1 year ago

The Phoenix Mars Lander, also called Phoenix, is a robotic spacecraft launched on a space exploration mission to Mars on August 7,2007.
According to recent NASA's news it seems that the $386-million spacecraft is on course and is set for landing on May 25. picked by cristeaiulian 4 months 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

"Another soil sample of the exact same composition as the last one..." "Still no water..." It's out of its mind with boredom. Another wonderful satirical story from The Onion. picked by Fanatic 2 years 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 8 months 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 8 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
