These solar arrays fold up like origami flowers

Posted by in category: space

Sending stuff up to space is no easy task — even 45 years after Apollo 11. Size, weight, and cost are all massively important, so some researchers are turning to advanced origami to fold up solar arrays. The result of their two years’ worth of work is a solar array with a diameter of just 8.9 feet (2.7 meters) when folded and a massive 82 feet (25 meters) when unfurled. A 1/20th scale model of the array is what you see here.

To build the solar array, Shannon Zirbel and professor Larry Howell of Brigham Young University, and mechanical engineer Brian Trease of NASA’s Jet Propulsion Laboratory, enlisted the help of renowned origami expert Robert Lang. One of the major difficulties faced by the team is that solar arrays are not as thin as paper. “You have to rethink a lot of that design in order to accommodate the thickness that starts to accumulate with each bend,” Trease said in a press release.

CERN chip enables first 3D color X-ray images of the human body

Posted by in categories: biotech/medical, computing, space

Medical X-ray scans have long been stuck in the black-and-white, silent-movie era. Sure, the contrast helps doctors spot breaks and fractures in bones, but more detail could help pinpoint other problems. Now, a company from New Zealand has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.

Mars Bioimaging, the company behind the new scanner, describes the leap as similar to that of black-and-white to color photography. In traditional CT scans, X-rays are beamed through tissue and their intensity is measured on the other side. Since denser materials like bone attenuate (weaken the energy) of X-rays more than soft tissue does, their shape becomes clear as a flat, monochrome image.

Researchers confine mature cells to turn them into stem cells

Posted by in categories: bioengineering, biotech/medical, genetics, life extension, space

Recent research led by Professor G.V. Shivashankar of the Mechanobiology Institute (MBI) at the National University of Singapore (NUS) and the FIRC Institute of Molecular Oncology (IFOM) in Italy, has revealed that mature cells can be reprogrammed into re-deployable stem cells without direct genetic modification — by confining them to a defined geometric space for an extended period of time.

“Our breakthrough findings will usher in a new generation of stem cell technologies for tissue engineering and regenerative medicine that may overcome the negative effects of geonomic manipulation,” said Prof Shivashankar.

New Higgs Boson Discovery Could Help Solve Cosmic Puzzle

Posted by in categories: particle physics, space

Scientists can’t take pictures of the Higgs boson. But they can find proof of its existence by watching “E=mc” play out in hundreds of millions of particle collisions per second and detecting how it decays into other particles they do know how to spot. Now, six years after officially discovering the Higgs boson, particle physicists are announcing that they’ve spotted the Higgs in another way.

This announcement isn’t a surprise. It matches the predictions of the Standard Model of particle physics, the rock-solid but probably incomplete blueprint of the Universe on the smallest scales. But the news is certainly important; you might say it closes the first chapter of the Higgs boson’s story, and offers a potential window to explore some of most confounding questions in the Universe.

Amazing Map Shows Every Space Probe Now Exploring Our Solar System

Posted by in category: space

They say outer space is a lonely place, but a new chart shows that some regions have gotten a bit crowded. It purports to show the positions of all the space probes now at work snapping photos and collecting data in our solar system.

Story continues below.

How many Extra Solar Planets or Exoplanets have been discovered as of today?

Posted by in categories: space, sustainability

As of today, July 10, 2018. There are 3081 Exoplanets discovered and confirmed so far… Exoplanets are planets orbiting other stars or found outside our solar system.

These planets orbiting from 2842 stars. We consider these as other solar systems from which 633 of these stars have multiple planets orbiting around them just like our own solar system.

A trillion-dollar space industry will require new markets

Posted by in categories: economics, finance, space

RENTON, Wash. — Forecasts that predict the space industry to grow to a trillion dollars by the 2040s will require the development of new markets, even with the modest annual growth rates needed to achieve that goal.

A panel session June 26 at the Space Frontier Foundation’s NewSpace 2018 conference here noted that several reports in the last year by investment banks predicted that the global space economy, currently valued at about $350 billion, could grow to $1 trillion or more in the 2040s.

One report by Goldman Sachs predicted the industry would reach $1 trillion in the 2040s, noted Jeff Matthews, a consultant with Deloitte who moderated the panel discussion. A separate study by Morgan Stanley projected a “most likely outcome” of a $1.1 trillion space economy in the 2040s. A third study by Bank of America Merrill Lynch was the most optimistic, seeing the market growing to $2.7 trillion by the same timeframe.

Jupiter’s Moons Leave Signature Spots in Its Aurorae

Posted by in category: space

Despite being wildly different from Earth in almost every way, Jupiter does feature some familiar phenomena—including aurorae, what we call the Northern and Southern lights. But Jupiter’s aurorae have something Earth’s don’t: strange features caused by the Jovian moons.

Scientists analyzing data from the Juno spacecraft spotted some of these anomalies in action. They saw swirls and spots caused by Jupiter’s moons Io and Ganymede. And, as is often the case, things weren’t what they seemed from far away.

Milky Way still bears the 10-billion-year-old scars of a galactic collision

Posted by in category: space

Galaxies collide with each other on a pretty regular basis. Our own Milky Way, for instance, has gobbled up dozens of smaller galaxies in the past, and Andromeda is currently hurtling towards us at 109 km (68 mi) per second. An international team of astronomers has now found evidence of a celestial smash-up between the Milky Way and an unknown dwarf galaxy that took place around eight to 10 billion years ago, and forever changed the face of our home galaxy.

According to the researchers, the evidence for this cosmic collision is all around us, from the bulge at the center of the Milky Way to the spread-out halo at the very fringes. The now-defunct dwarf galaxy has been dubbed the “Gaia Sausage,” after the ESA’s Gaia satellite used to plot out the trajectories of its stars, and the apparent shape those measurements revealed.

“We plotted the velocities of the stars, and the sausage shape just jumped out at us,” says Wyn Evans, co-author of the study. “As the smaller galaxy broke up, its stars were thrown out on very radial orbits. These Sausage stars are what’s left of the last major merger of the Milky Way.”
