An 18-year-old from Tamil Nadu in India has built what experts are hailing as the “world’s lightest satellite.” Bonus: NASA’s going to send it into space. Rifath Shaarook’s 1.5-inch cube weighs a mite 2.2 ounces—lighter than many smartphones. “We built it completely from scratch,” Shaarook told India’s Business Standard . “It will have a new kind of on-board computer and eight indigenous built-in sensors to measure acceleration, rotation and the magnetosphere of the Earth.” The satellite beat more than 86,000 entries from 57 countries to win Cubes in Space , a design competition organized by education nonprofit iDoodle with the support of NASA and the Colorado Space Grant Consortium . Shaarook named his design KalamSat after A. P. J. Abdul Kalam, India’s former president and a famous aerospace scientist in his own right.

Comments Off on Stephen Hawking: Humans must leave Earth within 100 years to survive

Would you like to travel to Mars? Get in line. According to Stephen Hawking , humans need to leave planet Earth within 100 years or perish due to overpopulation, climate change , disease and artificial intelligence. In the past, Hawking claimed that humans had about 1,000 years left on the planet. In BBC’s Expedition New Earth documentary, however, he states that humans must colonize Mars within the next century if they have any hope of survival. Throughout the program, Hawking reveals the technological and scientific advances that will enable life to exist on other planets . According to BBC , the documentary will show “Hawking’s ambition isn’t as fantastical as it sounds—that science fact is closer to science fiction than we ever thought.” Related: Stephen Hawking announces plan to explore Alpha Centauri for alien life The goal to transport billions of people to colonies on Mars may not be as outlandish as it seems. After all, Elon Musk of SpaceX is already planning to send humans (on a one-way trip) to Mars within the next decade, reports The Telegraph. Some, such as columnist Eric Mack, are shaking their heads at the notion, however. In an article published on Forbes , Mack expressed that a reality check is needed for anyone who believes Mars, the moon, or other nearby planets are more hospital than Earth after countless disasters. “Just cleaning up our own mess and starting over by rising from the rubble seems more practical” and more affordable than learning new methods of growing food or surviving radiation poisoning on Mars, he wrote . The columnist also added that “somehow, the grass is always greener for some people, even when it’s on a dead Red Planet.” + Expedition New Earth Via Telegraph

Comments Off on A mile-wide asteroid is flying uncomfortably close to Earth tomorrow

A mile-wide asteroid is about to swing by the Earth in the closest shave we’ve had in over a decade. Nicknamed ‘The Rock’ because of its massive size, the asteroid is barreling towards us at 75,072 mph – and it’ll fly past Earth at 4.6 times the distance of the moon. Scientists don’t know much about The Rock – it was only spotted 3 years ago – but we do know that it is twice as reflective as the moon, so you might be able to see it fly past on its way through the galaxy. Object 2014 J025 will fly 1,097,590 miles away from the earth tomorrow – and it won’t be this close again for at least another 400 years. We’ll be safe here on the ground, but it is also a pretty close shave – scientists call it “among the strongest asteroid radar targets of the year.” A large ~2 km asteroid, 143404 (2003 BD44), will pass safely by the Earth today (22 Lunar Distance) pic.twitter.com/X4pWnQyjo1 — Ron Baalke (@RonBaalke) April 18, 2017 Related: Scientists capture first ever image of dark matter web that connects galaxies The Rock should pass by around 8:24 am (Eastern).

While there isn’t any chance it will hit Earth, it is a startling reminder of how close space debris comes to smacking into the planet all the time. Via the Daily Mail images via NASA and Kevin Gill

NASA announces alien life could be thriving on one of Saturn’s moons

Comments Off on NASA announces alien life could be thriving on one of Saturn’s moons

In a live broadcast today, NASA researchers announced the agency has uncovered the existence of key ingredients for life as we know it on Saturn’s icy moon, Enceladus . Scientists already knew that the moon had liquid water on the surface, due to the presence of geysers spewing water near the moon’s south pole. Now, hydrogen has been detected in those jets of water, which suggests the strong possibility that Enceladus’s oceans could support microbial life. It may seem strange that an ice-covered world like Enceladus is being looked at as a potential source of extraterrestrial life, but beneath the planet’s icy shell spans a worldwide ocean over a rocky core. The ice is thought to act as a protective outer layer for the sea, the same way that our atmosphere protects Earth and makes life possible on our own planet. In fact, NASA is closely observing many of these “ ocean worlds ” for signs of life. While Enceladus’s geysers have been known to scientists since 2005, this is the first time the Cassini probe has been able to detect any traces of possible life within them. It’s believed that the plumes originate in a hydrothermal system within the moon’s core, estimated to be 2 1/2 times more powerful than the one that drives Yellowstone’s geysers and hot springs. Despite the icy outer shell, the gravitational pull of Saturn provides heat for the water in the moon’s interior, another encouraging sign for the development of life. Related: Trump plans to strip NASA’s earth science division, promote mission to Mars This new information about the moon comes from October 2015, when the Cassini craft flew into the plumes themselves, a mere 30 miles above the moon’s surface. The probe was able to capture particles from the plume inside a piece of equipment called an Ion Neutral Mass Spectrometer, which can analyze the makeup of material encountered on its journey through space. The probe detected a number of interesting organic molecules, including molecular hydrogen, carbon dioxide, and methane. The level of hydrogen , in particular, was surprising to researchers . This volatile gas isn’t easily captured on small, icy worlds like Enceladus, so there must be some chemical process beneath the surface producing the molecules. It may be that hot water from the ocean is flowing into iron-rich cracks in the sea floor, causing a chemical reaction that is constantly replenishing the ocean’s supply of molecular hydrogen. This is the same process that happens in Earth’s own hydrothermal vents , which helps fuel the strange and diverse ecosystems of the deep oceans. Because we’re familiar with exactly how this process supports Earth life, there’s a strong possibility that life could thrive on Enceladus in the same way. Unfortunately, we don’t currently have the instruments necessary to detect life directly on these watery worlds – only to look for the chemical indications of an environment that could potentially support it. Related: NASA discovers 7 Earth-sized planets outside our solar system NASA also today announced that they had found evidence of similar water plumes on Jupiter’s moon Europa , though less is known about their makeup. Unlike the Saturn Cassini mission, scientists don’t currently have an up-close view of Europa. Instead, they had to rely on data from the Hubble Space Telescope , which has been monitoring the moon to try to learn more about the makeup of its oceans. We may not know for certain until the 2020s, when NASA’s Europa Clipper mission is scheduled to launch. Via NASA Images via NASA/JPL

6 space farming projects that could save the human race

Comments Off on 6 space farming projects that could save the human race

What will humans eat on Mars ? It’s a daunting question: the red planet’s frigid average temperature is around negative 80 degrees Fahrenheit and its thin atmosphere is comprised of 95.32 percent carbon dioxide . But not to worry, future astronauts. NASA’s on it, as are several other institutions worldwide. Inhabitat rounded up six exciting space farming projects revealing the progress scientists have made on the issue of sustainable space cuisine. Scientists grow potatoes in Mars-like conditions, justifying The Martian’s Mark Watney Scientists from the International Potato Center , NASA’s Ames Research Center , and Peru’s University of Technology and Engineering recently showed the 2015 movie The Martian may have not just been science fiction after all. Inside a CubeSat , a small satellite in which the scientists could simulate Mars conditions, they were able to sprout potatoes , the crop of choice for astronaut Mark Watney in the film. Their research shows maybe we could grow those tubers on Mars after all, but also could offer insight into how to cultivate crops here on Earth in climate change -impacted regions. Related: Six scientists just completed a year-long simulated Mars mission Scientists find four crops grown in Mars-like soil are edible Wageningen University scientists in the Netherlands have also been growing crops in Mars-like soil. They successfully cultivated ten crops – like tomatoes, rye, and peas – in dirt provided by NASA that came largely from a Hawaii volcano, but feared the resulting food might be filled with heavy metals . Further tests showed they didn’t have to worry quite so much: at least four of the crops do not contain heavy metals like cadmium, lead, or arsenic and are edible. The Wageningen team hopes to continue their research and raise more money for their project. Astronauts harvest lettuce on the International Space Station International Space Station (ISS) astronauts are in on the space farming effort too. In 2014, Orbital Technologies Corporation’s Veggie system was deployed to the ISS , and recently in late 2016, NASA checked in with space gardener astronaut Shane Kimbrough who has harvested multiple batches of lettuce on the space station. The experiment not only gives astronauts the chance to nibble on some rare fresh greens harvested every ten days or so, but will also further NASA’s knowledge of how different life forms perform in zero gravity environments. Self-contained greenhouse could grow plants with Earth air on Mars The Mars Plant Experiment (MPX) was a small, self-contained greenhouse with enough Earth air to last 15 days and around 200 seeds of the flowering plant Arabidopsis used often in research. The little greenhouse would have hitched a ride to Mars aboard a rover for the 2020 mission. One of 58 proposed experiments, MPX didn’t make the list of seven selected payload proposals NASA announced a little over two months after Inhabitat’s article, but it’s still an intriguing idea for how humans might go about growing plants on Mars. NASA Advanced Food Technology team designs over 100 vegan recipes for future Mars crew Forget freeze-dried ice cream. NASA’s Advanced Food Technology project took a healthier approach by looking into an entirely vegan diet for future space voyagers. They developed more than 100 vegan recipes for a six to eight person Mars crew, featuring fresh fruits and vegetables possibly grown in hydroponic systems. Veganism wasn’t so much a ideological choice for the NASA team as a practical one: it would be difficult to store easily perishable dairy and meat products during the lengthy trip to Mars. Experts suggest kitchen garden for astronauts venturing to Mars All the way back in 2011, NASA was pointing to kitchen-style gardens as a solution for astronauts, realizing pre-packaged food alone probably wouldn’t cut it for deep space missions. Speaking at an American Chemical Society gathering, scientist Maya Cooper of NASA’s Space Food System Laboratory said chefs and horticultural experts could help devise a plan for producing the over 7,000 pounds of food required for the five year journey to Mars. Experts identified 10 likely candidates for a spaceship kitchen garden: cabbage, spinach, herbs, carrots, strawberries, tomatoes, peppers, spring onions, radishes and lettuce – of course we’re now growing that last plant already on ISS. In just over five years, scientists have come a long way in developing space farming , and we’re excited to see what innovations crop up in the upcoming years as humanity prepares to go to Mars.

Comments Off on Incredible video of Mars stitched together by hand from 33,000 images

If you’ve ever wanted to get up-close and personal with Mars , check out this incredible video recently released by NASA that shows the Red Planet’s surface in stunning detail. Entitled “A Fictive Flight Above Real Mars,” the video is a composite made from about 33,000 of the 50,000 high-resolution stereo images of the planet’s terrain made over the past 12 years by the powerful camera used in NASA’s High Resolution Imaging Science Experiment (HiRISE). These stereogram images depict the planet’s surface in incredible detail, which can only truly be appreciated in still images by using 3D glasses—or when merged together into an active, three dimensional, fly-over view, as was done by Finnish filmmaker Jan Fröjdman when creating this video. As Wired notes, Mars’ dusty atmosphere obfuscates its surface with massive storms so regularly that the only way to get a decent look at the planet is through imaging technology. So that’s what NASA did. “The best way to see the planet’s surface would be to take a digital image and enhance it on your computer, said planetary geologist and principal investigator for HiRISE, Alfred McEwen. Related: The UAE joins the race to build first city on Mars https://vimeo.com/207076450 Enter Fröjdman, who assembled the flyover shots piece by piece and colorized the monochrome images captured by the HiRISE camera. He was also responsible for identifying features like craters, canyons and mountains, then matching them between pairs of images. The 3D panning effect was the result of a painstaking process that involved stitching the images along reference points and then rendering them as frames in a video. Fröjdman spent three months working on the project, during which time he picked and stitched by hand more than 33,000 images. The result of his work is worth the effort—a truly stunning video.

Trump plans to strip NASAs earth science division, promote mission to Mars

Comments Off on Trump plans to strip NASAs earth science division, promote mission to Mars

On Tuesday, President Donald Trump signed into law a new plan for NASA’s future . The NASA Transition Authorization Act of 2017 calls for a $19.5 billion annual budget for the agency – not a major change from the agency’s $19.3 billion budget in 2016 – but the document seems to leave out the agency’s earth science division entirely. Trump claims this is simply a way of reaffirming the agency’s “core mission” of human space exploration, space science, and technology, but given how aggressively the new administration has gone after any agencies involved in atmospheric research, climate change denial is likely the underlying motive for the shift. Under the new act, Congressional Republicans have outlined a new roadmap for the agency’s future. The law calls on NASA to create a plan for humans to reach the surface of Mars by the 2030s, and to continue developing its Orion space capsule and its Space Launch System. The administration has also expressed a desire for NASA to return to the moon in the 2020s. Related: NASA releases startling new images showing 30 years of change on Earth What’s unclear is exactly how the new law will affect NASA’s earth science research. Trump’s proposed budget , however, may offer some clues. He hopes to cut the earth science budget by $102 million, potentially terminating a number of programs, including the   Plankton, Aerosol, Cloud, ocean Ecosystem  (PACE),  Orbital Carbon Observatory-3  (OCO-3),  Deep Space Climate Observatory  (DISCOVR), and  CLARREO Pathfinder missions. These four satellites help scientists monitor the Earth’s climate, weather, and oceans. While Trump may claim climate change is outside of the scope of NASA’s original research mission, that’s simply untrue. When NASA was formed in 1958, the National Aeronautics and Space Act explicitly called on the new agency to contribute to the “expansion of human knowledge of phenomena in the atmosphere.” The loss of these resources would be devastating to the larger scientific world, which often relies on NASA data for research. Related: Gov. Jerry Brown pledges to launch California’s “own damn satellite” if Trump blocks climate research It’s still far too early to know what might happen: the funding requested would be for the 2018 fiscal year, so any cuts wouldn’t be felt immediately. The proposed budget also has to be reviewed and approved by Congress before anything is set in stone. Hopefully, lawmakers will see the value in maintaining some of these programs, even if Trump doesn’t. Via Business Insider Images via   NASA

Comments Off on NASA releases images of the world’s largest solar farm from space

China is home to the world’s largest solar farm , which is so immense, it is visible from space. With around four million solar panels , Longyangxia Dam Solar Park has a capacity of 850 megawatts (MW) – pushing the country closer to its ambitious renewable energy goals. NASA recently shared satellite images of the solar park as seen from space – and they are admittedly impressive. The award for world’s largest solar farm has switched hands rapidly in the last few years. In 2014, California’s 550 MW Topaz Solar Farm was the biggest, but a year later the state’s 579 MW Solar Star claimed victory. The next year, 2016, saw India’s 648 MW Kamuthi Solar Power Project topple the throne, only to be ousted by the Longyangxia Dam Solar Park this year. Related: India just fired up the world’s largest solar plant to power 150,000 homes NASA Earth Observatory’s satellite images of the Chinese solar park reveal immense growth over four years. By early January of this year, the Longyangxia Dam Solar Park, which is in the high desert of the Qinghai province, covered 10 square miles. China became the largest producer of solar power in the world after the country’s total installed capacity increased to around 77 gigawatts in 2016, even though other countries like the United States and Germany produce more solar energy per person. Rapid progress has marked China’s renewable energy industry in recent years. According to Climate Central, drawing on preliminary 2016 data released by Greenpeace’s Energydesk , the country “installed the equivalent of one and a half soccer fields of solar panels every hour.” Such advancement means China could hit their 2020 renewable energy targets as soon as 2018. NASA doesn’t expect the Longyangxia Dam Solar Park to retain the crown for long. The Mohammed bin Rashid al Maktoum Solar Park in Dubai is still growing – phase 3 will add 800 megawatts to the farm. And another solar farm planned for China’s Ningxia region in the northwest is slated to have a capacity of 2,000 MW. Via Climate Central Images via Jesse Allen/NASA Earth Observatory

Comments Off on Dakota Access Pipeline 99 percent finished, says Energy Transfer Partners

After months of protests by Native Americans and supporters worldwide, the Trump administration ignored the pleas of so many American citizens and gave permission for the hotly contested Dakota Access Pipeline to move forward. And Energy Transfer Partners didn’t waste much time doing just that. The group said in a recent statement that the oil pipeline is now 99 percent finished. Federal authorization came earlier in February and Energy Transfer Partners got to work. In March or April, oil could start flowing through the $3.8 billion pipeline, which will transport Bakken crude oil from North Dakota oilfields through the Midwest. The oil will end up at refineries near the Gulf of Mexico. The part of the pipeline that runs so close to the Standing Rock Sioux reservation is the last to be completed. Related: Standing Rock protesters evicted by police at gunpoint White House Press Secretary Sean Spicer indicated that the White House is communicating with the Standing Rock Sioux Tribe. In a press briefing yesterday, a reporter asked if the President had been briefed on the Standing Rock situation, and Spicer replied, “Our team has been involved with both the tribe and the governor there, and so we are not only – we are constantly in touch with them. And I think we feel very confident that we will move forward to get the pipeline moving.” But tribe chair Dave Archambault II said Spicer’s claims aren’t true. The Standing Rock Sioux Tribe issued a statement yesterday and quoted Archambault II as saying, “[Spicer’s] claim is absolutely false. We repeatedly asked for meetings with the Trump administration, and never received one until the day they notified Congress that they were issuing the easement. I was on a plane to Washington, D.C. when the easement was issued. It was an insult to me and to the Tribe. I cancelled the meeting upon hearing this news. We have since filed a lawsuit for the immoral and illegal issuance of the easement and suspension of the environmental impact study.” Via Reuters Images via Standing Rock Rising Facebook
