ISRO space ride can cost less than the Uber rides

According to some reports, ISRO planning to launch space rides which would charge passengers on per kilometer rate and it would be cheaper than current Uber ride rates. This looks possible as we all know that recently ISRO successfully launched Mangalyaan which only costs around Rs 600 crore, much less than NASA expenditure on similar project. USA and EU space agencies are not reacting to the new which shows there rates might not be as cheaper.

Trump hugely cuts NASA budget by $200 Million

Of all the federal agencies which recently received budgets from Trump administration, NASA has seen the mild cuts in funding (0.8%) and environment protection agency facing the major cut (31%). A few upcoming missions are cancelled one of them involving sending robots towards asteroids to wrangle large boulder off of it and establishing it in moons orbits and to do further research on that.

Scientist to use moon to help search for exploding stars

Moon would help scientist to better locate the exploding stars in Milky Way galaxy and even beyond that. Lunar Occultation Explorer (LOX) would orbit moon and take advantage of its relatively quiet lunar environment, where there is less background noise. It will be the first astrophysics mission to the moon.

Nasa will give you $30,000 (£24,000) if you can figure out a better way for astronauts to go toilet in space
At the moment when they’re at the International Space Station they use a funnel device to urinate and a vacuum if they want to do a number two. But sometimes it takes astronauts a couple of days to get to the base and when journeys to Mars begin travel time is going to be even longer. They may also have to wear pressure suits in an emergency, which don’t even allow them to scratch their noses. More at: http://metro.co.uk/

Will humans LEAVE Earth? Pentagon space expert says nations must work to ‘get off this planet and onto another

The idea of moving the human race from Earth to another planet might sound like the plot of the latest sci-fi blockbuster. But that is exactly what top Pentagon space experts say will need to happen in the future. Speaking at a summit, Winston Beauchamp, deputy undersecretary of the Air Force for space, said nations must work together to ‘get the human race off this planet onto another planet.’ He said: ‘There is an erosion of some of the commonly accepted standards and norms, and there’s concern about that as folks around the world have tried to find advantage, find seams.

HYPERSONIC planes to send humans to space in MINUTES close to reality

Flight times around the world would also be dramatically reduced, with the supersonic jet able to reach five times the speed of sound – approximately 1,716 metres per second. The speed could see a flight from London to New York take just one hour and get the craft into space – roughly 62 miles – in a matter of minutes. Michael Smart, professor of hypersonics at the University of Queensland, Australia, is using scramjets to create the speedy jet. Much like jet engines, scramjets drawer in air and compress it to burn fuel. Unlike jets, scramjets have no moving parts and rely on the hypersonic speed of the craft to compress air within the motor. More at: http://www.express.co.uk/

Massive ‘Black Hole’ On Sun’s Surface Could Blast The Earth: Hoax Or Real?

A massive coronal hole on the sun is recently discovered to be facing the Earth creating a couple of solar storms directly to our planet. The said solar storm is believed to have a huge potential adverse effect on the communication and electrical systems especially if the Earth’s magnetic field was hit by some charged particles, causing these problems to arise. Daily Mail has recently reported that several cautionary advisories have already been released by the operator of the biggest power grid in the US. Experts also claim that the warnings based on space weather forecast may not just affect some parts of the world but could possess a global impact. More at: http://www.itechpost.com/

Physicist says our Universe could have spawned from a black hole

According to our best understanding of the Universe, if you travel back in time as far as you can, around 13.8 billion years or so, you’ll eventually reach a singularity – a super-dense, hot, and energetic point, where the laws that govern space-time breakdown. Despite our best attempts, we can’t peer past that singularity to see what triggered the birth of our Universe – but we do know of only one other instance in the history of our Universe where a singularity exists, and that’s inside a black hole. And the two events might have more in common than you’ve ever considered, as physicist Ethan Siegel explains over at Forbes. More at: http://www.sciencealert.com/

Obama pushes NASA to send humans to Mars by 2030s

President Barack Obama sought Tuesday to reinvigorate his six-year-old call for the U.S. to send humans to Mars by the 2030s, a mission NASA has been slowly and quietly trudging away at. The White House was calling attention to government contracts awarded to six companies to build prototypes for “habitats” that could sustain human life in deep space. One such privately developed habitat an inflatable room is already attached to the International Space Station. Obama also said thatwithin two years, private companies like SpaceX and Boeing will taxi astronauts to the space station with NASA as a customer. More at: http://indianexpress.com/

This massive black hole just broke free, and is tearing through its own galaxy

Supermassive black holes are thought to sit at the centre of every galaxy in the Universe. It’s not clear why they’re always in the middle, but we’re safe in the knowledge that those devastating whirlpools of nothingness stay where they’re supposed to… until they don’t. A newly discovered black hole appears to have been knocked from its perch by another galaxy, and is now tearing – unanchored – through its own galaxy. Let’s all just take a moment to appreciate the very well-behaved black hole at the centre of the Milky Way, shall we? Regular black holes form when a star at least five times more massive than the Sun runs out of fuel, and collapses in on itself to create a destructive void that not even light can escape. There are also massive black holes – sometimes referred to as intermediate-mass black holes – which are 100 to 100,000 times more massive than our Sun. More at: http://www.sciencealert.com/

Evidence for a wandering black hole

Astronomers think that supermassive black holes, with some 100,000 to 10 billion times the mass of our sun, are located in the centers of most galaxies. There’s also evidence for the existence of so-called intermediate mass black holes, which have lower masses ranging between about 100 and 100,000 times that of the sun. In recent years, they’ve found evidence for both types of objects, not in galaxy centers, but away from them. They call these objects wandering black holes and believe they result from galaxy collisions and mergers. The most recent candidate is an object called XJ1417+52, and it was found at the edge of a lenticular galaxy some 4.5 billion light years from Earth. More at: http://earthsky.org/

Astronomers Find Wandering Black Hole in Galaxy 4.5 Billion Light-Years Away

Astronomers know that black holes ranging from about 10 times to 100 times the Sun’s mass are the remnants of dying stars, and that supermassive black holes, with some 100,000 to 10 billion times the Sun’s mass, inhabit the centers of most galaxies. But scattered across the Universe are a few apparent black holes of a more mysterious type. Ranging from 100 to 100,000 solar masses, these intermediate-mass black holes are much harder to find. According to scientists, both supermassive and intermediate-mass black holes may be found away from the center of a galaxy following a collision and merger with another galaxy containing a massive black hole. As the stars, gas and dust from the second galaxy move through the first one, its black hole would move with it. More at: http://www.sci-news.com/

NASA rethinks approach to Mars exploration

NASA is looking at a new way of studying Mars. Starting in the 2020s, scientists who participate in the agency’s Mars missions might no longer design and build their own highly specialized payloads to explore the red planet. Instead, planetary scientists could find themselves operating much as astronomers who use large telescopes do now: applying for time to use a spacecraft built with a generic suite of scientific instruments. The proposed change is spurred by NASA’s waning influence at Mars. The agency’s long-running string of spacecraft is winding to a close, and international and commercial interests are on the rise. By the middle of the next decade, European, Chinese, Emirati and SpaceX missions are as likely to be at Mars as NASA is. Jim Watzin, head of NASA’s Mars exploration programme in Washington DC, suggested the new approach to the red planet on 6 October at a virtual meeting of a Mars advisory group. “The era that we all know and love and embrace is really coming to an end,” he said. “It’s important to recognize that the future is not going to be the same as the past.” More at: http://www.nature.com/news

NASA Wants Ideas for the Next Electric Airplane

ASA is leading the charge toward the next step in electrically powered aviation. Even as the X-57 Maxwell—a demonstrator of distributed electric propulsion and the agency’s first crewed X-plane in decades—is being assembled, the agency has released a Request for Information (RFI) to solicit ideas for a follow-on. The new RFI, released on September 16, calls for electric or electric-hybrid concepts in one (or more) of four categories: a conventional airplane capable of carrying four to nine people; a vertical-takeoff-and-landing (VTOL) airplane for at least one person; a regional jet-sized airplane capable of operating in airspace under current regulations; and a catch-all that essentially means “good ideas that don’t fit in the previous bins.” Tantalizingly, the RFI specifically suggests that the first three objectives could be used to address a production aircraft. More at: http://www.airspacemag.com/

NASA Identifies 13th Sign of the Zodiac: ‘We Just Did the Math’

The National Aeronautics and Space Administration (NASA) has identified a 13th sign of the zodiac between Sagittarius and Scorpius: Ophiuchus, also known as the “serpent bearer” because it appears in the middle of the Serpens constellation. But NASA was quick to point out that “we didn’t change any zodiac signs… we just did the math.” The ancient Babylonians invented the 12 signs of the zodiac to match their 12-month lunar calendar, NASA pointed out in a recent Tumblr post. But they “ignored the fact that the sun actually moves through 13 constellations, not 12” during Earth’s year-long orbit around the sun. “Even then, some of the chosen 12 didn’t fit neatly into their assigned slice of the [celestial] pie and crossed over into the next one,” NASA pointed out. For example, “the line from Earth through the sun points to Virgo for 45 days, but it points to Scorpius for only 7 days.” More at: http://www.cnsnews.com/

NASA has new gecko bots that can climb anything

NASA’s done a lot of cool things. Y’know, going to the moon, launching probes outside of our solar system, and playing a huge role in the construction of the International Space Station. Now the association has turned their focus towards… gecko-bots? That might sound weird, but it makes a lot of sense when you start to think about it. Space is really hard to move about it. Whether you’re trying to maneuver around on alien words, climb vertical surfaces, or even just anchor yourself to an asteroid or a space station, you’re going to need some help. According to WIRED, researchers at NASA’s Jet Propulsion laboratory have taken inspiration for insects and geckos to create robots that can deal with just about any surface. More: http://www.geek.com/

Making space rocket fuel from water could drive a power revolution on Earth

Researchers led by NASA’s former chief technologist are hoping to launch a satellite carrying water as the source of its fuel. The team from Cornell University, guided by Mason Peck, want their device to become the first shoebox-sized “CubeSat” to orbit the moon, while demonstrating the potential of water as a source of spacecraft fuel. It’s a safe, stable substance that’s relatively common even in space, but could also find greater use here on Earth as we search for alternatives to fossil fuels. Until we develop a warp drive or some other futuristic propulsion system, space travel is likely to rely largely on the kind of propellant-based rockets we use today. These work by firing gas out of the rear of the vehicle in a way that, thanks to the laws of physics, pushes it forward. Such propulsion systems for satellites need to be lightweight and carry a lot of energy in a small space (high energy density) in order to continuously pack a powerful punch over the many years, or even decades, that the craft are in orbit. More at: http://theconversation.com/

The Universe Is Directionless, Study Finds

The universe, it turns out, looks the same in every direction. Of course, this isn’t true on a “small scale” — the stars, galaxies, dark matter and interstellar gas that fill the universe are strewn about and clumped together in unique ways. But on a much size scale encompassing the entire universe, new research shows the cosmic landscape doesn’t have any preferred direction — there’s no axis of spin like the Earth, no massive asymmetries that would orient a cosmic traveler. The new study appears to be the most in-depth attempt to answer this question, which confirms a long-held assumption in physics. In addition, it touches on the idea that Earth does not occupy a special place in the universe by showing that not only is no preferred location in the universe, there is no preferred direction.  More at: http://www.space.com/

Stephen Hawking Says The Human Race Has No Future If It Doesn’t Go To Space

The physicist believes this world could be destroyed by nuclear war or a man-made virus. When he was offered a seat on Richard Branson’s Virgin Galactic Space Ship Two vehicle, Stephen Hawking immediately said yes. In the foreword for How to Make a Spaceship by Julian Guthrie, published in The Guardian, the physicist states his belief in the potential of commercial space travel, both for exploration and the preservation of humanity. More at: http://time.com/

Icy Giant Planet Found Growing Around Nearby Star

TOKYO:  Scientists have found signs of a baby planet thought to be an icy giant – similar to Uranus and Neptune – growing around a nearby star, a discovery that may help better understand the origins of various types of planets.  Astronomers spotted the planet around TW Hydra, a nearby young star, using the Atacama Large Millimetre/submillimetre Array (ALMA) in Chile.  Based on the distance from the central star and the distribution of tiny dust grains, the baby planet is thought to be an icy giant, similar to Uranus and Neptune. A number of extrasolar planets have been found in the past two decades and now researchers agree that planets can have a wide variety of characteristics. However, it is still unclear how this diversity emerges. More at: http://www.ndtv.com/

Our Interstellar Neighbors: 5 Potentially Earth-Like Planets Nearby

A possibly Earth-like planet has been found within the habitable zone of humanity’s closest stellar neighbor, Proxima Centauri, and astronomers think the world could potentially support life. While there is still a lot to learn about this newfound world, called Proxima Centauri b or just Proxima b, astronomers are sure of a few things: The Earth-like rocky exoplanet is 4.2 light-years away; its minimum mass is 1.3 times that of the Earth, and it orbits Proxima Centauri every 11.2 days. Astronomers also said that Proxima b lies within the habitable zone of Proxima Centauri, which means the planet orbits a safe distance from the star, making it neither too hot or too cold. Because of this, astronomers said that Proxima b may have suitable surface temperature that would allow for the presence of liquid water, meaning the exoplanet could support some sort of life. More at: http://www.space.com/ 

Stunning Before and After Space Pics Reveal Massive Ice Avalanche

One of the world’s largest, and most mysterious ice avalanches was recently visualized in stunning pictures from space. A huge sliver of ice split off from a vast glacier in the Aru Mountains of Tibet, falling nearly 0.6 miles (1 kilometer) before tumbling through a narrow gully and plunging into a nearby lake. When the ice and rock settled, the avalanche debris spanned 4 square miles (10 square km) and was 98 feet (30 m) thick. The massive avalanche killed nine people, 350 sheep and 110 yaks that lived in the village of Dungru.

Space Photos of the Week: A Lazy Supernova in the Sky

This supernova might be beautiful, but it’s also lazy. This composite x-ray image shows the remains of a supernova explosion called RCW 103 with a suspected magnetar star—aka “highly magnetized neutron star”—at its center. The magnetar has a mysteriously slow spin, rotating only once ever 6.67 hours, compared to the 10 seconds other magnetars typically take.  More at: https://www.wired.com

Countless tiny black holes might be hurtling through space like cosmic bullets

First, the good news: you have not been killed by a black hole. The bad news is that it’s possible the Universe is teeming with microscopic black holes that formed at the dawn of time, all of them hurtling through space like cosmic bullets. Some could weigh nearly as much as Earth’s Moon, others an asteroid, and still more somewhere in between. Whatever their weight, most would be smaller than the period in this sentence. Astrophysicists are running out of options to explain what most of the stuff in the Universe is made of. They know roughly 80 percent of it is dark matter, which exerts a gravitational pull on the other 20 percent – ‘normal’ matter – yet has remained invisible to experiments for more than 80 years. More at: http://www.sciencealert.com/

Nasa to make all its research available free on the Internet

The American space agency, Nasa, is to make all its research available free of charge. It is a move which will delight science enthusiasts and aspiring astronauts. Normally such material is hidden behind a paywall, meaning that it is often out of reach for the lay enthusiast. The EU has also said it hopes to make all its research available free from 2020. “At NASA, we are celebrating this opportunity to extend access to our extensive portfolio of scientific and technical publications,” said Dava Newman, NASA’s  Deputy Administrator. “Through open access and innovation we invite the global community to join us in exploring Earth, air and space.” More at: http://www.telegraph.co.uk/

Space May Be the Best Place to Grow Bone Formation Protein Crystals

Crystals of proteins that could be useful in medical research can be grown bigger and better in space than on Earth, according to the results of experiments performed on the International Space Station.

Medical research often focuses on examining how proteins work. That can include learning how to use proteins in medicines, or finding proteins that cause problems for humans and making drugs to fight them. A better understanding of a protein’s 3D structure can, for example, help scientists improve how well a medicine works, or find out the best ways to kill a germ. To decipher a protein’s 3D structure, researchers often make the protein into a crystal (so it is frozen in a rigid pose) and then scan the crystals with X-rays or neutron beams. The larger and purer a protein crystal is, the better the chance that scientists can work out that protein’s 3D structure. More at: http://www.space.com/

Ready to live in deep space? Just wait NASA has started to develop habitats for our journey

We may not yet be able to live in deep space, but we can already check out our proposed accommodations, thanks to NASA’s plan to build deep space habitats here on Earth. It’s all part of the space agency’s latest project known as NextSTEP-2, which involves the selection of six U.S. companies “to help expand knowledge, commercial capabilities, and opportunities in space by developing full-sized ground prototypes and concepts for deep space habitats.” NASA says that the goal is to provide support for lengthier and more involved human space flight missions, which will lead to Mars missions. This will also advance commercial development of space while moving forward with deep space exploration capabilities. The result will be more extensive human space flight missions by the moon that will be the proving grounds for Mars. “The NextSTEP partnerships are a large contribution to the dual objectives of advancing deep space habitation development and stimulating commercial activities in low-Earth orbit,” said Jason Crusan, Director of Advanced Exploration Systems at NASA Headquarters. More at: http://www.digitaltrends.com/

We may be about to solve one of the biggest mysteries in the universe

In case you haven’t heard, there is a very, very big problem with the universe: About 80% of all of the stuff inside of it can’t be found. Astronomers call this missing material “dark matter.” They know it’s out there because its huge mass tugs on and shapes galaxies. Aside from exerting a gravitational pull, however, dark matter doesn’t seem to interact with stars, planets, dust, atoms, subatomic particles, fancy scientific instruments, or any other “normal” matter as we know it. It’s essentially invisible. Yet this deep cosmic mystery, which has perplexed scientists for nearly 85 years, may soon come to a close – possibly within the next year. NASA cosmologist Alexander Kashlinsky thinks the recent and groundbreaking discovery of gravitational waves could help rule out the idea that dark matter is made of exotic, hard-to-detect particles. More at: http://www.techinsider.io/

NASA discovers more than 104 new planets beyond our solar system

NASA’s Kepler spacecraft have discovered 104 new planets outside our solar system, including four that could have Earth-like surfaces. The team discovered the exoplanets using the Kepler space telescope as well as Earth-based telescopes, including four on the summit of Mauna Kea in Hawaii. The four potentially rocky planets are between 20 to 50 per cent larger than Earth, and orbit tightly around the same star in a system about 400 light-years from us. Even though the planets rotate around their star even closer than Mercury orbits the sun, astronomers said two of them may have surface temperatures similar to Earth’s, as their star is cooler than our sun. The unmanned $600-million Kepler mission has allowed scientists to discover more than 4,600 planets – more than half of them confirmed – since it launched in 2009. More at: http://www.abc.net.au/news

China Plans to Build Own Space Station Similar to ISS

China is developing its own space station and is building a new site which will be used to launch space stations and space technology. The trial run for the new rocket was a success so the construction of the station will begin in 2018. It is likely that China will play a leading role in this sphere and might replace the ISS program, in which Japan also participates. Hainan Island is located in the south of China. On June 25 the new space station which was built in one part of this island, a new Changchan-7 rocket, was launched. The station will be located at about 400 kilometers from Earth.

Russia also is entertaining the idea of operating its own space station after 2024. As for the United States, with which Japan has to keep pace, its attention is currently focused on the program of a manned flight to Mars set to take place in 2030. More at: http://sputniknews.com/asia

Good news: the hole in the ozone layer is finally starting to heal

A new study in Science finds evidence that the Earth’s protective ozone layer is finally healing — all thanks to global efforts in the 1980s to phase out CFCs and other destructive chemicals. This is one of the great environmental success stories of all time. Back in the 1970s, scientists first realized that we were rapidly depleting Earth’s stratospheric ozone layer, which protects us from the sun’s harmful ultraviolet rays. The culprit? Chlorofluorocarbons (CFCs), a chemical widely used in refrigerators and air conditioners. These chemicals had already chewed a massive “hole” in the ozone layer above Antarctica, and the damage was poised to spread further north.

Strange planet has triple sunsets and a super-long year

A bizarre solar dance has been uncovered by researchers who spotted a giant planet orbiting one of the three suns of a triple-star system. The system was found in the constellation Centaurus, about 98 parsecs (320 light years) from Earth1. As shown in an artist’s impression in this video, the planet, called HD 131399Ab, orbits the largest of the three stars. The other two stars also orbit the largest, and each other. A year on the planet lasts for about 550 Earth years. For the first few hundred years, when the planet is on the side of the system opposite all three stars, the team says that it will experience three sunrises and three sunsets each day. During its second ‘season’, it is in constant daylight.

PIA13746-16NASA’s DAWN mission over dwarf planet Ceres has come to an end

After traveling 3.5 billion miles, the DAWN spacecraft has reached the end of its primary mission over Ceres, a dwarf planet that sits in the asteroid belt between Mars and Jupiter. Since departing in 2007, DAWN became the first vehicle to orbit two separate objects, and the first to visit our Solar System’s asteroid belt for detailed study. As it approached Ceres in the spring of 2015, DAWN sent back thousands of detailed images of the dwarf planet, revealing incredible new features on its surface. Once the spacecraft entered a series of mapping orbits on March 6th, it began providing scientists with new data about the composition, structure and terrain of the object. Over the course of its mission, it completed 2,450 orbits around both Vesta and Ceres, and returned almost 70,000 images back to Earth.
