    NASA ^ | Wednesday, June 22, 2016 | (see photo credit)
    Explanation: What's that over Paris? Cirrus. Typically, cirrus clouds appear white or gray when reflecting sunlight, can appear dark at sunset (or sunrise) against a better lit sky. Cirrus are among the highest types of clouds and are usually thin enough to see stars through. Cirrus clouds may form from moisture released above storm clouds and so may herald the arrival of a significant change in weather. Conversely, cirrus clouds have also been seen on Mars, Jupiter, Saturn, Titan, Uranus, and Neptune. The featured image was taken two days ago from a window in District 15, Paris, France, Earth.

    Explanation: What's older than these ancient trees? Nobody you know -- but almost everything in the background of this picture. The trees are impressively old -- each part of the Ancient Bristlecone Pine Forest located in eastern California, USA. There, many of the oldest trees known are located, some dating as far back as about 5,000 years. Seemingly attached to tree branches, but actually much farther in the distance, are the bright orbs of Saturn (left) and Mars. These planets formed along with the Earth and the early Solar System much earlier -- about 4.5 billion years ago. Swooping down...

    So... it could still get us to Mars in 70 days? Physicists have just published a new paper that suggests the controversial EM drive - or electromagnetic drive - could actually work, and doesn't defy Newton's third law after all. In case you've missed the hype, here's a quick catch-up: a lot of space lovers are freaking out about the EM drive because of claims it could get humans to Mars in just 10 weeks, but just as many are sick of hearing about it, because, on paper at least, it doesn't work within the laws of physics. Despite that...

    My father died a few days ago. He was 100 years old. I never met his parents, he barely knew them himself. His mother, the daughter of a Russian Jewish immigrant who fought for the Union, taught second grade in New York City public schools. She died when he was three, in the flu epidemic of 1918-1919, one of the greatest disasters in American history. A quarter of the American population, including President Wilson, caught the disease, and 700,000 died from it -- twice as many as fell in World War II. In New York City people were dying so...

    Explanation: Seen any planets lately? All three planets now shining brightly in the night sky are imaged in these panels, captured last week with the 1 meter telescope at Pic du Midi Observatory in the French Pyrenees. Near opposition and closest to Earth on May 30, Mars is presently offering the best ground-based photo-ops in the last decade. The sharp image finds clouds above the Red Planet's north pole (top) and towering volcanos near its right limb. Saturn reaches its own opposition tonight, its bright rings and gaps clearly revealed in the telescopic portrait. Jupiter is currently highest during the...

    Explanation: Mars will look good in Earth's skies over the next few days -- but not this good. To get a view this amazing, a spacecraft had to actually visit the red planet. Running across the image center, though, is one the largest canyons in the Solar System. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris...

    By 2030, Russia will send robots to the Moon to collect samples. The program will be punctuated with a manned Moon landing — 60 years after Neil Armstrong’s Apollo mission. Payback, perhaps, for losing out on the major leg of the U.S. and Soviet space race. The optimistic program also lays out plans for active exploration of other planets in the solar system, and ideas for a follow-up to the International Space Station: The ISS is only funded until 2020.
  • Russia and Europe plan a manned mission to Mars

    Europe will carry out the first manned mission to Mars together with Russia. Head of the European Space Agency Jean-Jacques Dordain stated this when he visited the International Aviation and Space Salon, MAKS-2011, now under way in Zhukovsky near Moscow. He gave no timeframe, but head of the Russian Space Agency Vladimir Popovkin welcomed his European counterpart’s idea concerning the coordination of the future project. The dream of human beings going to Mars has a long history, and at present, mankind is very close to implement such a project. Some time ago, an interest in the planet was linked to...

    Russia enters 'space race' to build moon base By Graeme Baker Last Updated: 5:57pm BST 31/08/2007 Russia has revived another Cold War rivalry by entering a new “space race” with America to build a permanent base on the Moon. The moon from Moscow's Novodevichy Monastery Anatoly Perminov, the head of the space agency Roskosmos, said Russia would organise a manned lunar mission by 2025 and would be ready to build an “inhabited station” between 2027 and 2032. From there, cosmonauts could strike out on a long-planned mission to Mars as early as 2035. “According to our estimates we will be...

    If Martians exist, they'll be closer to Earth on Memorial Day than they have been in 11 years. This Monday, around 5:34 p.m. EDT, when many Americans may be enjoying a holiday barbecue, the Red Planet will be the closest it has been to Earth in more than a decade, coming within 46.8 million miles, according to NASA. The relatively close encounter with Earth comes a week after the Martian opposition, when Mars and the sun lined up on exact opposite sides of the Earth.

    Had you searched the sky with a telescope just a few hundred thousand years ago, you would have struggled to find a red planet. Instead, you would have seen a gleaming-white ice ball where Mars should be. A team of astronomers led by Isaac Smith, an astrophysicist at the Southwest Research Institute in Boulder, Colorado, has collected the first concrete evidence that Mars has just exited an extreme ice age, one so intense it would have put Earth's recent frosty foray to shame. Using cameras and a radar-pinging device on board NASA's Mars Reconnaissance Orbiter, Smith's team deduced this history...

    India successfully launched a scale model of a reusable spacecraft on Monday, a project that in time could pit the nation against billionaires Jeff Bezos and Elon Musk in the race to make access to space cheaper and easier. The winged vessel -- one-fifth of full size -- blasted off on a rocket from Sriharikota base on the southeastern coast, the Indian Space Research Organisation said. The spacecraft reached an altitude of 65 kilometers (40 miles) and glided back at supersonic speeds for a splashdown in the Bay of Bengal. The test took about 13 minutes.

    Explanation: In this early May night skyscape, a mountain road near Bursa, Turkey seems to lead toward bright planets Mars and Saturn and the center of our Milky Way Galaxy, a direction nearly opposite the Sun in planet Earth's sky. The brightest celestial beacon on the scene, Mars, reaches its opposition tonight and Saturn in early June. Both will remain nearly opposite the Sun, up all night and close to Earth for the coming weeks, so the time is right for good telescopic viewing. Mars and Saturn form the tight celestial triangle with red giant star Antares just right of...
  • Mars Is Ready For Its Close-Up: Red Planet Easy To Spot This Weekend

    Sometimes astronomy can be challenging, but spotting Mars this weekend should be a breeze. Step 1: Head outside right after sunset and look toward the southeastern sky. Step 2: Find the full moon. (So far, so good, right?) Step 3: Look up and to the right, and find what looks like a bright red star. That's Mars, our planetary neighbor — getting up close and personal. This weekend is the "Mars opposition," when the planet shines most brightly; at the end of the month, in a related event, we'll have the "Mars close approach," when there's the shortest distance between...
  • Humans on Mars: Scouting Needed for Red Planet Resources

    Space.com ^ | 05/16/2016 | Leonard David,
    Last year, scientists proposed nearly 50 locations on Mars as possible places for future human landings. Those landing-zone sites contain "regions of interest" that can be reached from primary touchdown spots. Good touchdown sites will allow crews to land safely and carry out operations; offer a wealth of interesting science activities; and provide resources that the astronauts could use. For example, any favored exploration zone should allow expeditionary crews to tap into at least 100 metric tons (110 U.S. tons) of water, NASA officials have said. With its suite of instruments and cameras — particularly the sharp-shooting High Resolution Imaging...

    "The idea of suspended animation for interstellar human spaceflight has often been posited as a promising far-term solution for long-duration spaceflight," said Dr John Bradford, CEO of the firm. The cryosleep system works by chilling humans and artificially inducing a state of hypothermia so astronauts can hibernate for up to two weeks. A similar technique is already used to cool the body of someone who has suffered a cardiac arrest in a bid to avoid brain damage. This would allow just one space man or woman to maintain the ship, meaning the spacecraft could be much smaller and travel more...

    The red planet will soon be closer to Earth that it has been in 11 years: On May 30, Mars will be about 46.8 million miles (75.3 million kilometers) from Earth. Yes, that’s still a long way off, but sometimes Mars is 249 million miles (400 million kilometers) from Earth. What does this close approach mean for sky watchers? It means Mars will appear bigger and brighter from May 18 until June 3, according to NASA. But you don’t have to wait. Mars already is putting on a spectacular show in the early morning sky. And you don’t need a...

    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...

    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...

    NASA can't afford to put humans on Mars while also pursuing missions to put astronauts back on the moon, according to a panel of experts who testified to the U.S. House of Representatives Subcommittee on Space yesterday (Feb. 3). "Today the future of NASA's human spaceflight program is far from clear," said Tom Young, former director of NASA's Goddard Space Flight Center. "There has been continual debate about should we go to the moon or Mars or both ... It is clear, again, that we cannot do both. And there is a need to focus our attention, capability and resources...

    Scientists Debate Signatures of Alien Life Searching for signs of life on faraway planets, astrobiologists must decide which telltale biosignature gases to target. Photo illustration by Olena Shmahalo/Quanta Magazine February 2, 2016 Comments (5) Share this: facebooktwitterredditmail PDF Print Huddled in a coffee shop one drizzly Seattle morning six years ago, the astrobiologist Shawn Domagal-Goldman stared blankly at his laptop screen, paralyzed. He had been running a simulation of an evolving planet, when suddenly oxygen started accumulating in the virtual planet’s atmosphere. Up the concentration ticked, from 0 to 5 to 10 percent.“Is something wrong?” his wife asked.“Yeah.”The rise of...

    Explanation: As January closes and in the coming days of February, early morning risers can spot the five naked-eye planets before dawn. Though some might claim to see six planets, in this seaside panoramic view all five celestial wanderers were found above the horizon along with a bright waning gibbous Moon on January 27. Nearly aligned along the plane of the ecliptic, but not along a line with the Sun, the five planets are spread well over 100 degrees across the sky. Just arriving on the predawn scene, fleeting Mercury stands above the southeastern horizon in the golden light of...

    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...

    Could a Mars colony become a nation? That question was posed by Michael Byers, who holds the Canada Research Chair in Global Politics and International Law at the University of British Columbia in a Washington Post article. Byers’ answer to his question was yes. A body of international law has evolved over time that recognizes the rights of people to self-determination.

    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...

    There are several space stories we’re anticipating for 2016 but one story might appear — to some — to belong in the realm of science fiction: sometime in the coming year Elon Musk will likely reveal his plans for colonizing Mars. Early in 2015, Musk hinted that he would be publicly disclosing his strategies for the Mars Colonial Transport system sometime in late 2015, but then later said the announcement would come in 2016.

Come September, an outer ring of the sun's annular eclipse will be visible across Africa. In between, there will be spectacular shooting stars, super moons, and lunar eclipses to take in. ... From about Jan. 20 to Feb. 20, all five planets that are visible to the naked eye — Mercury, Venus, Mars, Jupiter and Saturn — will occupy the morning sky. This hasn't happened since 2005, according...

    Astrobiology ^ | Wednesday, December 23, 2015 | Keith Cooper
    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...
