Mars, the only planet whose surface we can see in any detail from the Earth, is now moving toward the best viewing position it will provide to us until the year 2014. Planet watchers have already begun readying their telescopes. picked by AutumnLotus 1 year ago

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.

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 1 year ago

Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice. That's the global picture literally and figuratively coming into much sharper focus as various Mars-orbiting cameras send back tomes of unprecedented su... read full post picked by AutumnLotus 1 year 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 12 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 12 months 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

The solar system's smallest planet has been shrinking at an unexpected rate, researchers announced on Thursday.

When NASA's Mariner 10 probe flew by Mercury in 1974 and 1975, it returned images of strange cliffs called 'scarps' that cut across all sorts of geological formations. That suggested that the planet's surface has contracted over time. picked by AutumnLotus 5 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

Peering beneath the ice at the north pole of Mars has now revealed the Red Planet may be surprisingly colder than was thought.

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 12 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 12 months ago

Mars will be closer to Earth this month than any time until the year 2016. The red planet is now the brightest "star" in the evening sky and is already above the horizon as evening twilight fades away. But give it at least two more hours – until about 8 p.m. – for it to climb above the poor atmospheric seeing that's near the horizon. By then, this brilliant yellow-orange worl... read full post picked by AutumnLotus 12 months ago

The hottest planet ever discovered is charcoal black and makes even some stars seem cool. Scientists think the exoplanet absorbs nearly all the starlight that reaches its surface and then reradiates it back out into space as heat. picked by AutumnLotus 2 years ago

The Phoenix Mars Lander, also called Phoenix, is a robotic spacecraft launched on a space exploration mission to Mars on August 7,2007.

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 1 year ago

A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun. The planet has a mass that is nearly six times that of Jupiter, the largest planet in our solar system. picked by AutumnLotus 2 weeks ago
