    If Donald Trump or Hillary Clinton don't resonate with American voters, they always have Andrew Basiago -- a presidential candidate who is pretty sure he's going to become "either president or vice-president" between 2016 and 2028, according to information he's gathered time travelling. Cheekily calling his campaign "a time for truth," Basiago, 54, brags on his site that he "served bravely in the two secret U.S. defence projects in which time travel on Earth and voyages to Mars were first undertaken." Basiago -- who has made similar claims in the past -- also said he's helped several former presidents make...

    In the movie, "The Martian," Matt Damon was a fictional astronaut stranded on Mars. In reality, the head of NASA says astronauts could set foot on the Red Planet within the next twenty years. "We think we're on the right trajectory to get humans to Mars in the 2030's," NASA Administrator Charles Bolden told CNBC's "On the Money" in an interview this week. He should know: Prior to assuming NASA's top job in 2009, Bolden was himself an astronaut for 14 years, commanding two space shuttle missions during that time. The U.S.'s top space official says he's confident the agency's...

    WASHINGTON (AFP) - A first-ever high-resolution map of Mars' entire magnetic field provides new evidence that Earth-like plate tectonics - great crustal plates pulling apart and crashing together - underpin the Red Planet's surface geology, US space agency NASA said. Using the map made by the National Aeronautic and Space Administration's Mars Global Surveyor spacecraft, scientists were able to detect signs of transform faults, which are tell-tale indications of plate tectonics on Earth. The results of the scientists' research appeared in the October 10 edition of the journal Proceedings of the National Academy of Sciences. Evidence of plate tectonics at...

    The travel time from Earth to Mars using current space flight technologies is estimated to be 9 months. Last week, an innovative concept was proposed which claims to reduce the time that will be spent for Mars travel to merely three days through so-called photonic propulsion technology. But a new proposal threatens to radically shorten this period to an astounding 30 minutes. The idea was revealed by Phillip Lubin, who is a physics professor at the University of California Santa Barbara. Lubin was also responsible for the photonic propulsion technology proposal. This time, however, he identified the use of high-powered...

Mars' original north and south poles, in other words, are no longer where they once were. The findings explain the unexpected location of dry river beds and underground reservoirs of water ice, as well as other Martian mysteries that have long perplexed scientists, the lead researcher told AFP.

    Explanation: What caused this unusual light rock formation on Mars? Intrigued by the possibility that they could be salt deposits left over as an ancient lakebed dried-up, detailed studies of these fingers now indicate a more mundane possibility: volcanic ash. Studying the exact color of the formation indicated the possible volcanic origin. The light material appears to have eroded away from surrounding area, indicating a very low-density substance. The stark contrast between the rocks and the surrounding sand is compounded by the unusual darkness of the sand. The featured picture was taken with the Thermal Emission Imaging System on the...

    The hunt for signs of life on Mars has been on for decades, and so far scientists have found only barren dirt and rocks. Now a pair of astronomers thinks that strangely shaped minerals inside a Martian crater could be the clue everyone has been waiting for. In 2008, scientists announced that NASA's Spirit rover had discovered deposits of a mineral called opaline silica inside Mars's Gusev crater. That on its own is not as noteworthy as the silica's shape: Its outer layers are covered in tiny nodules that look like heads of cauliflower sprouting from the red dirt. No...

    After a year-and-a-half long voyage aboard the International Space Station, a group of fungi collected from Antarctica has proven its ability to withstand harsh, Mars-like conditions. More than half of the cells remained intact over the course of the 18-month study, providing new insight for the possibility of life on Mars. These fungal samples, along with lichens from Spain and Austria, have allowed European researchers to assess the survivability and stability of microscopic lifeforms on the red planet. The tiny fungi taken from Antarctica are typically found in the cracks of rocks in this dry, hostile region. Scientists took samples...

    Charles D. Walker (a former commercial astronaut), kicked up something of a fuss recently when he opined in the pages of the Arizona Daily Star that NASA should lead the way in space exploration and not leave everything to the private sector. The reasons he cites are risk and lack of a clear profit motive, particularly related to going to Mars. The commercial space sector should be encouraged to bring down the cost of space travel, particularly by operating a space taxi service to the International Space Station, in his view. But NASA must lead the way in exploration, particularly...

    Explanation: What is that dark sand dune doing on Mars? NASA's robotic rover Curiosity has been studying it to find out, making this the first-ever up-close investigation of an active sane dune on another world. Named Namib Dune, the dark sand mound stands about 4 meters tall and, along with the other Bagnold Dunes, is located on the northwestern flank of Mount Sharp. The featured image was taken last month and horizontally compressed here for comprehensibility. Wind is causing the dune to advance about one meter a year across the light bedrock underneath, and wind-blown sand is visible on the...

    In 1993, French astronomer Jacques Laskar ran a series of calculations indicating that the gravity of the Moon is vital to stabilizing the tilt of our planet. Earth's obliquity, as this tilt is technically known as, has huge repercussions for climate. Laskar argued that should Earth's obliquity wander over hundreds of thousands of years, it would cause environmental chaos by creating a climate too variable for complex life to develop in relative peace. So his argument goes, we should feel remarkably lucky to have such a large moon on our doorstep, as no other terrestrial planet in our solar system...

    Measure it any way you like, but this hasn't been that championship season of the "can do" spirit of America. Most of the presidential campaigners spend their allotted minutes criticizing what's wrong with the country, how others have made a mess of things and why voters should put them in charge of changing things. It's difficult to find the formula through the haze of confusion and fog of rhetoric. There's far more blowhard nastiness than creative eloquence.

    Most studies of potential Earth-smashers focus on objects in the asteroid belt roughly between Mars, Earth's outside neighbour, and Jupiter on its other flank, said the researchers. But they noted that the discovery in the last two decades of hundreds of giant comets dubbed centaurs, albeit with much larger orbits, requires expanding the list of potential hazards. These balls of ice and dust, typically 50-100 kilometres (31-62 miles) wide, have unstable, elliptical orbits that start way beyond Neptune, the most distant planet from the Sun. Their paths cross those of the giant planets Jupiter, Saturn, Uranus and Neptune, whose gravity...

    In a finding that suggests "considerable water activity" on Mars, NASA says its Curiosity rover has found very high concentrations of silica on the red planet. The agency says it also found "a mineral named tridymite, rare on Earth and never seen before on Mars." The discoveries took place on Mount Sharp, where Curiosity drilled into a rock called "Buckskin" to find the tridymite, and where it used its "ChemCam" laser to measure high silica levels. The odd findings led researchers to take the rare step of ordering Curiosity to retrace its path to learn more. Explanations for the high...

    Explanation: They might look like trees on Mars, but they're not. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The above image was taken in 2008 April near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks -- streaks that might appear at first...

    Caltech and JPL scientists suggest the fingerprints of early photochemistry provide a solution to the long-standing mystery. Mars is blanketed by a thin, mostly carbon dioxide atmosphere—one that is far too thin to prevent large amounts of water on the surface of the planet from subliming or evaporating. But many researchers have suggested that the planet was once shrouded in an atmosphere many times thicker than Earth's. For decades that left the question, "Where did all the carbon go?" Now a team of scientists from Caltech and JPL thinks they have a possible answer. The researchers suggest that 3.8 billion...

Taken before dawn it traces the ecliptic with a line-up familiar to November's early morning risers. Toward the east are bright planets Venus, Mars, and Jupiter as well as Regulus, alpha star of the constellation Leo. Of course the planets are immersed in the faint glow of zodiacal light, visible from the dark site rising at an angle from the horizon. Sometimes known as the false dawn, it's no accident the zodiacal light and planets both lie along the ecliptic....

    Phobos survived a giant impact early in its history, but damage from the crash left the moon weak, say Benjamin Black and Tushar Mittal, planetary scientists with University of California at Berkeley. Their study shows that in 20 million to 40 million years, Phobos will break apart, leaving a cloud of debris that will relatively quickly assembly into a ring around Mars. Initially, the ring will be as dense as Saturn's rings today, and it will last for up to 100 million years, the study shows.

    Explanation: Is there anything interesting to see in the direction opposite the Sun? One night last month, there were quite a few things. First, the red-glowing orb on the lower right of the featured image is the full moon, darkened and reddened because it has entered Earth's shadow. Beyond Earth's cone of darkness are backscattering dust particles orbiting the Sun that standout with a diffuse glow called the gegenschein, visible as a faint band rising from the central horizon and passing behind the Moon. A nearly horizontal stripe of green airglow is also discernable just above the horizon, partly blocked...

    Explanation: On November 8, a waning crescent Moon joined the continuing parade of planets in Earth's morning skies. Captured here from Amboseli National Park, Kenya, even the overexposed moonlight can't washout brilliant Venus though, lined up near the ecliptic plane with faint Mars and bright Jupiter above. As if Moon and planets aren't enough, a comparably bright Taurid meteor also streaks through the scene. In fact November's Taurid meteor showers have had a high proportion of bright fireballs. Apparently streaming from radiants in Taurus, the meteors are caused by our fair planet's annual passage through debris from Comet 2P/Encke. The...
  • Mars’ Moon Phobos Undergoing ‘Structural Failure’

    One of the most striking features we see on images of Phobos is the parallel sets of grooves on the moon’s surface. They were originally thought to be fractures caused by an impact long ago. But scientists now say the grooves are early signs of the structural failure that will ultimately destroy this moon. "We think that Phobos has already started to fail, and the first sign of this failure is the production of these grooves," said Terry Hurford, from NASA’s Goddard Space Flight Center. ... Mars' gravity is pulling in Phobos closer by about 2 meters (6.6 feet) every...

    Explanation: What's that in the sky? Although there was much to see in this spectacular panorama taken during the early morning hours of a day in late September, the brightest object in the sky was clearly the planet Venus. In the featured image, Venus was captured actually through a natural rock bridge, itself picturesque, in Spitzkoppe, Namibia. The planet, on the left of the opening, was complemented by a silhouette of the astrophotographer on the right. Above and beyond the rock bridge were many famous icons of a dark night sky, including, from left to right, the Pleiades star cluster,...
  • Why Earth is so much bigger than Mars: Rocky planets formed from 'pebbles'

    Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year. "This numerical simulation actually reproduces the structure of the inner solar system, with Earth, Venus, and a smaller Mars," said Hal Levison, an Institute scientist at the SwRI Planetary Science Directorate. He is the first author of a new paper published in the Proceedings of the National Academy of Sciences...

    Explanation: It was visible around the world. The sunset conjunction of Jupiter and Venus in 2012 was visible almost no matter where you lived on Earth. Anyone on the planet with a clear western horizon at sunset could see them. Pictured above in 2012, a creative photographer traveled away from the town lights of Szubin, Poland to image a near closest approach of the two planets. The bright planets were separated only by three degrees and his daughter striking a humorous pose. A faint red sunset still glowed in the background. Jupiter and Venus will be at it again this...

(Don Dixon/Erik Sturkell/University of Gothenburg) It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago. Researchers from the University of Gothenburg uncovered two craters in the county of Jmtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor...

    The discovery of water on the surface of Mars, which just happened to coincide with the premiere of the hit film The Martian, starring Matt Damon as an astronaut marooned on the Red Planet, has caused some degree of excitement for space enthusiasts. NASA is particularly inspired because its central organizing project is the journey to Mars which is scheduled to put astronauts on the Martian surface by the 2030s. The discovery and the movie certainly would not hurt the effort to gin up support for the humans to Mars program.

    In the early years of the 20th century, zeppelins filled with flammable and explosive hydrogen were all the rage in Germany, a reckless infatuation that ended with the eruption and crash of the Hindenburg in 1937. Sometimes, technology is a triumph of wild-eyed enthusiasm over the unpleasant facts of the real world. Today we are witnessing a similar outburst of enthusiasm over the literally outlandish notion that in the relatively near future, some of us are going to be living, working, thriving and dying on Mars ... Unfortunately, this Mars mania reflects an excessively optimistic view of what it actually...

    Explanation: What creates these changing streaks on Mars? Called Recurring Slope Linea (RSL), these dark features start on the slopes of hills and craters but don't usually extend to the bottom. What's even more unusual is that these streaks appear to change with the season, appearing fresh and growing during warm weather and disappearing during the winter. After much study, including a recent chemical analyses, a leading hypothesis has emerged that these streaks are likely created by new occurrences of liquid salty water that evaporates as it flows. The source for the briny water is still unclear, with two possibilities...
