If you ever wanted to participate in spacesuit design, even in a small way, here’s your big chance. NASA is asking the public to choose which design of the futuristic Z-2 “planetary mobility” suit prototype will be used by astronauts while evaluating how well the spacesuit works. There are three options (which you can see above), and NASA promises the winning design will be used in pool training at NASA’s Neutral Buoyancy Laboratory, the Johnson Space Center “rockyard” to simulate Mars exploration, and in vacuum tests. Outer space is not an option because of “micrometeorite, thermal and radiation protection” considerations,...

The six wheeled Martian dune buggy drove into the dazzling Kimberly waypoint this week after traversing a swath of otherworldly dune fields since passing through a gateway known as the ‘Dingo Gap’ sand dune some six weeks ago. The robot’s arm has been deployed to investigate the most scientifically productive spots to touch Kimberly’s textured outcrops for detailed scrutiny. The science team has been hunting for tasty rock outcrops suitable for the first drilling campaign since she departed the dried out lakebed at Yellowknife Bay in July 2013 and began her epic trek across the floor of Gale Crater towards...

Explanation: Deep shadows create dramatic contrasts between light and dark in this high-resolution close-up of the martian surface. Recorded on January 24 by the HiRISE camera onboard the Mars Reconnaissance Orbiter, the scene spans about 1.5 kilometers across a sand dune field in a southern highlands crater. Captured when the Sun was just 5 degrees above the local horizon, only the dune crests are caught in full sunlight. With the long, cold winter approaching the red planet's southern hemisphere, bright ridges of seasonal frost line the martian dunes.

A NASA spacecraft has spotted a big gully on Mars, a feature that appears to have formed only within the last three years. The powerful HiRISE camera on NASA's Mars Reconnaissance Orbiter (MRO) imaged the channel, which is found on the slope of a crater wall in the Red Planet's mid-southern latitudes, on May 25, 2013. The feature was not present in HiRISE photos of the area taken on Nov. 5, 2010. NASA unveiled the image on Wednesday (March 19). While the Mars gully looks a lot like river channels here on Earth, it likely was not carved out by...

Many of the primitive bodies wandering the asteroid belt between Mars and Jupiter are former comets, tossed out of orbit by a brutal ballet between the giant outer planets, said a team of astrophysicists. A commonly accepted theory is that the asteroid belt is the rubble left over from a "proto-planetary disk," the dense ring of gas that surrounds a new-born star. But the orbiting rocks have long been a source of deep curiosity. They are remarkably varied, ranging from mixtures of ice and rock to igneous rocks, which implies they have jumbled origins. The answer to the mystery, according...

For scientists who spend time thinking about how planets form, life would be simpler if gas giants like Jupiter and Saturn didn’t exist. According to the standard model of planet formation, called "core accretion," planets form over millions of years as enormous blocks of rock and ice smash together to form planetary embryos, called "protoplanets," and eventually full-fledged planets. Most scientists agree that core accretion is how terrestrial planets such as Earth and Mars were created, but the model can’t convincingly explain how gas giant planets like Jupiter and Saturn came to be. One major problem is that developing gas...

Interesting discussions and photos of varying rock types encountered on Mars to date.

What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image right. Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep. Why there is a circular crater surrounding this hole remains a topic of speculation, as...

Explanation: Get out your red/blue glasses (red for the left eye) and look out over this expansive martian landscape. The panoramic stereo view is composed of images from the roving Curiosity's Navcam taken at a rest stop during a 100 meter drive on Sol 548 (February 19). The 5.5 kilometer high peak of Mount Sharp, also known as Aeolis Mons, is on the horizon, its base a destination for Curiosity. In the foreground are rows of striated rocks along the Junda outcrop. Centered toward the south-southeast the scene spans 160 degrees. (Another Navcam image here looks back along Curiosity's route...

Congress has Mars in its eyes. In the wake of a hearing last week, the US House Committee on Science, Space and Technology has asked NASA to consider a crewed fly-by of the Red Planet in 2021. The venture's funding and feasibility remain vague, however, and NASA's 2015 budget plan, released today, maintains that an asteroid will be the first destination for astronauts riding the agency's next-generation space capsule. The Mars fly-by proposal is built on plans for a privately funded mission laid out by Inspiration MarsMovie Camera, a non-profit endeavour formed by multimillionaire Dennis Tito. Barely a year after...

Explanation: What would it be like to see a sunset on Mars? To help find out, the robotic rover Spirit was deployed in 2005 to park and watch the Sun dip serenely below the distant lip of Gusev crater. Colors in the above image have been slightly exaggerated but would likely be apparent to a human explorer's eye. Fine martian dust particles suspended in the thin atmosphere lend the sky a reddish color, but the dust also scatters blue light in the forward direction, creating a bluish sky glow near the setting Sun. Because Mars is farther away, the Sun...

Line up Mercury, Venus, Earth and Mars according to their distance from the sun and you'll see their size distribution is close to symmetrical, with the two largest planets between the two smallest. That would be no coincidence -- if the pattern emerged from a debris ring around the sun. Brad Hansen of the University of California, Los Angeles, built a numerical simulation to explore how a ring of rocky material in the early solar system could have evolved into the planets. He found that two larger planets typically form near the inner and outer edges of the ring, corresponding...

A tiny 4.4-billion-year-old crystal has been confirmed as the oldest fragment of Earth's crust. The zircon was found in sandstone in the Jack Hills region of Western Australia. Scientists dated the crystal by studying its uranium and lead atoms. The former decays into the latter very slowly over time and can be used like a clock. The finding has been reported in the journal Nature Geoscience. Its implication is that Earth had formed a solid crust much sooner after its formation 4.6 billion years ago than was previously thought, and very quickly following the great collision with a Mars-sized body...

Are you ready for some lunar versus planetary occultation action? One of the best events for 2014 occurs early this Wednesday morning on February 26th, when the waning crescent Moon — sometimes referred to as a decrescent Moon — meets up with a brilliant Venus in the dawn sky. This will be a showcase event for the ongoing 2014 dawn apparition of Venus that we wrote about recently. This is one of 16 occultations of a planet by our Moon for 2014, which will hide every naked eye classical planet except Jupiter and only one of two involving Venus this...

<p>FOR a few minutes on Christmas, children may set down their new toys from the man in the red suit and listen to transmissions from a machine on the red planet. On Thursday, the European Space Agency is scheduled to guide a British probe called the Beagle II onto the surface of Mars in what should become the first successful landing there since NASA's Mars Pathfinder in 1997. But while Mars grabs all the extraterrestrial attention this holiday ("The Beagle has landed!"), normally Christmas is the season of Jupiter, because there's a very good chance that the biggest planet in our solar system was the Star of Bethlehem.</p>

I apologize for the uncharacteristic way I've presented this. It's just that I've gotten involved in some project that's going to be taking amounts of my time for the foreseeable future. And having seen these sites, I've been trying to post it here in some organized, efficient way but just haven't been able to get to it as I usually do, being as involved as I am in this new endeavor, actually just couldn't get around to posting them but was feeling really guilty about not doing the right thing and my very favorite place in the whole world. Hope...

FaTwa reportedly issued warning Muslims not to make 'hazardous trip' to live on Mars Muslims have been warned in a Fatwa not to go and live on Mars because it would pose "a real risk to life", according to a Dubai news organisation.

Fatwa reportedly issued warning Muslims not to make 'hazardous trip' to live on Mars Muslims have been warned in a Fatwa not to go and live on Mars because it would pose "a real risk to life", according to a Dubai news organization. The General Authority of Islamic Affairs and Endowment (GAIAE) in the United Arab Emirates said that anyone making such a "hazardous trip" is likely to die for "no righteous reason". They would therefore be liable to a "punishment similar to that of suicide in the Hereafter", the Khaleej Times reported. The Fatwa was apparently issued in response...

A Fatwa has been issued against living on Mars by clerics who say that trying to set up home there would be un-Islamic. The fatwa – or ruling – was issued by the General Authority of Islamic Affairs and Endowment (GAIAE) in the UAE after the Mars One organisation announced that it would try and establish a permanent human settlement on Mars. The committee argued that an attempt to dwell on the planet would be so hazardous as to be suicidal and killing oneself is not permitted by Islam
