Is that a pistol in your pocket, or are you just… carrying an iPhone?

The Ideal Conceal handgun has made waves for what its maker calls an “ingenious” design that looks exactly like a smartphone when in the “locked” position.

Ideal Conceal says on its website that, indeed, hardly anybody will notice it: “Smartphones are EVERYWHERE, so your new pistol will easily blend in with today’s environment. In its locked position it will be virtually undetectable because it hides in plain sight.”

The Ideal Conceal weapon is a .380-caliber derringer. Two bullets in two barrels. While the gun is still patent-pending, It’s expected to be available by mid-2016 for $395 each.

“From soccer moms to professionals of every type, this gun allows you the option of not being a victim,” the company says. “Most threats will occur in less than a 30’ range. Ease and speed of deployment will mean the difference in the outcome. With the Ideal Conceal pistol you can be quick on the draw stopping a threat effectively and immediately.”

Ideal Conceal looks to be tapping into the gun market at an opportune time. Earlier this month, firearms giant Smith & Wesson SWHC, -0.62% rode a groundswell of demand to surprisingly strong quarterly results. The stock has more than doubled in the past year, as uncertainty over gun laws and the rising threat of terrorism have caused customers to load up.

Not everyone on social media reacted to the gun in the way Ideal Conceal may have hoped:

In the Autumn of 2014, NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft arrived at Mars and entered into orbit. MAVEN wasn’t the only visitor to arrive at Mars at that time though, as comet Siding Spring (C/2013 A1) also showed up at Mars. Most of MAVEN’s instruments were shut down to protect sensitive electronics from Siding Spring’s magnetic field. But the magnetometer aboard the spacecraft was left on, which gave MAVEN a great view of the interaction between the planet and the comet.

Unlike Earth, which has a powerful magnetosphere created by its rotating metal core, Mars’ magnetosphere is created by plasma in its upper atmosphere, and is not very powerful. (Mars may have had a rotating metal core in the past, and a stronger magnetosphere because of it, but that’s beside the point.) Comet Siding Spring is small, with its nucleus being only about one half a kilometer. But its magnetosphere is situated in its coma, the long ‘tail’ of the comet that stretches out for a million kilometers.

When Siding Spring approached Mars, it came to within 140,000 km (87,000 miles) of the planet. But the comet’s coma nearly touched the surface of the planet, and during that hours-long encounter, the magnetic field from the comet created havoc with Mars’ magnetic field. And MAVEN’s magnetometer captured the event.

Jared Espley is a member of the MAVEN team at Goddard Space Flight Center. He said of the Mars/Siding Spring event, “We think the encounter blew away part of Mars’ upper atmosphere, much like a strong solar storm would.”

“The main action took place during the comet’s closest approach,” said Espley, “but the planet’s magnetosphere began to feel some effects as soon as it entered the outer edge of the comet’s coma.”

Espley and his colleagues describe the event as a tide that washed over the Martian magnetosphere. Comet Siding Spring’s tail has a magnetosphere due to its interactions with the solar wind. As the comet is heated by the sun, plasma is generated, which interacts in turn with the solar wind, creating a magnetosphere. And like a tide, the effects were subtle at first, and the event played out over several hours as the comet passed by the planet.

Siding Spring’s magnetic tide had only a subtle effect on Mars at first. Normally, Mars’ magnetosphere is situated evenly around the planet, but as the comet got closer, some parts of the planet’s magnetosphere began to realign themselves. Eventually the effect was so powerful that the field was thrown into chaos, like a flag flapping every which way in a powerful wind. It took Mars a while to recover from this encounter as the field took several hours to recover.

MAVEN’s task is to gain a better understanding of the interactions between the Sun’s solar wind and Mars. So being able to witness the effect that Siding Spring had on Mars is an added bonus. Bruce Jakosky, from the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder, is one of MAVEN’s principal investigators. “By looking at how the magnetospheres of the comet and of Mars interact with each other,” said Jakosky, “we’re getting a better understanding of the detailed processes that control each one.”

Astronomers say they’ve found the biggest structure in the universe and they named it the BOSS

The BOSS is big. Really big. Yuuuuuge.

So big that when a star is born on one side of the BOSS, it takes a billion years for the light to reach the other side.

So big that comparing the BOSS to the next biggest thing like it is like comparing Andre the Giant to your 3-year-old nephew.

What is the BOSS? It’s a wall. A Great Wall. It makes other walls — you know which ones — look like, well, nothing, because the BOSS Great Wall is an immense complex comprising more than 800 galaxies and weighing 10,000 times as much as the Milky Way and other walls are just a measly pile of rocks on an insignificant planet in a remote part of space.


Anyway, scientists working for the Baryon Oscillation Spectroscopic Survey— the international galaxy-mapping effort from which the BOSS gets its truly spectacular acronym — say that the newly discovered cosmic feature is the largest structure in the universe. Or at least, as much of the universe as they’ve mapped so far.

In a study published in the newest issue of the journal Astronomy and Astrophysics, the scientists describe the BOSS Great Wall (BGW) as an enormous collection of galaxies more than one billion light-years across.

“It was so much bigger than anything else in this volume,” Heidi Lietzen of the Canary Islands Institute of Astrophysics, a lead author on the study, told the New Scientist.

“Walls” like the BGW are part of the underlying structure of the universe. Most of space is a vast empty void, and all the stuff that astronomers look for — stars, planets, the galaxies they constitute — is threaded through that nothingness. Pulled together by gravity, galaxies coalesce into clusters, which in turn form larger structures called superclusters, as explained by PBS. Those are then corralled into “walls” — the coronary arteries of this giant system of matter, and the biggest things in space.

Researchers for the Sloan Digital Sky Survey (the BOSS survey is one of its projects) have been trying to map that web in order to better understand the universe’s history, size and speed of expansion. Using a dedicated telescope located in the remote desert scrubland of Sunspot, N.M., they scan huge swaths of the sky for distant galaxies, brilliant quasars and other celestial objects.

In the process, they’ve found some pretty enormous things. Like the “Sloan Great Wall,” which Lietzen and her co-authors say is the closest system of superclusters comparable to the BGW.

But even that is dwarfed by the Sloan survey’s newest find. The BOSS Great Wall has ten times the volume of the Sloan wall and is almost 70 percent larger in diameter. It comprises four superclusters containing 830 galaxies, and it looms in space some 5 billion light-years away from Earth. (For what it’s worth, the biggest thing in our neck of the woods, the Laniakea supercluster that includes our own Milky Way galaxy, is less than half the size of the BGW.)

“I don’t entirely understand why they are connecting all of these features together to call them a single structure,” Allison Coil, an astrophysicist at the University of California at San Diego, told the New Scientist. “There are clearly kinks and bends in this structure that don’t exist, for example, in the Sloan Great Wall.”

But size isn’t really the point, Smithsonian Magazine noted. The discovery of the BOSS Great Wall is just one part of a larger survey that will — astronomers hope — reveal not just what the universe looks like, but how it’s evolved and how it continues to change.

Which is a very nice sentiment. But the BOSS Great Wall is still biggest. And you know what that makes it.

A winner.

NASA Plans to Light a Fire Inside a Spacecraft, Then Watch What Happens

Relax, it’s being done for science.

For the past couple of weeks, on and off, astronaut Tim Kopra has been playing with fire on the International Space Station—part of an experiment called Burning and Suppression of Solids—Milliken (BASS-M), to test how flame-retardant cotton fabrics burn in microgravity.

Why? Because fire behaves differently in space than it does on Earth. In normal gravity, hot gas rises, drawing in cool, fresh air at the base of the flame. That’s what gives flames their familiar teardrop shape. In microgravity, hot gas doesn’t rise, so flames tend to be wider, shorter, and rounder than on Earth. As a result, flames in space radiate heat differently than they do on Earth, which in turn affects how fires spread. That means materials may be more or less flammable in orbit than they are on Earth, even with the same mix of atmospheric gases.

When it comes to flammability tests, size matters. On Earth, NASA uses 5 cm by 25 cm samples of flammable material. But pieces that big aren’t allowed on the station (with some exceptions when there is no practical alternative, such as the crew’s clothing). So experiments like BASS-M (which follows up on earlier BASS combustion experiments carried out on the station from 2011 to 2013) make do with small samples, about one centimeter by three centimeters.

“The problem with small samples is that a lot of aspects of the fire don’t scale linearly, so you can’t look at a tiny, one-centimeter fire and extrapolate that to one that’s a foot wide or something,” said David Urban, a combustion researcher at NASA’s Glenn Research Center.

Scientists would like to know exactly how large-scale fires would grow and spread in microgravity, but it’s too dangerous to conduct that kind of experiment on a spacecraft with astronauts on board. Instead, safety engineers have to rely mostly on models based on how flames spread in Earth’s gravity, and on a few small combustion experiments in space.

Sometimes you just need a bigger fire. So Urban and co-investigator Gary Ruff designed the Spacecraft Fire Experiment (Saffire), a series of six tests that will ignite and study contained fires aboard returning Cygnus cargo ships (the next of which is scheduled to depart the station on Friday). When they leave the ISS, the Cygnus ships contain only trash, and they burn up during re-entry. They’re expendable, which makes them the perfect place to set a fire.

When the next Cygnus (number OA-6) launches on March 20, it will carry, along with new supplies for the station,  the experimental hardware for Saffire-I. A metal box with fans at either end houses a 0.4- by 0.94-meter sheet of SIBAL cloth, a blend of 75 percent cotton and 25 percent fiberglass. Cotton is used in crew clothing, towels, and other cloth items aboard the station, and the fiberglass blend keeps the sample material from ripping and tearing as it burns. The fans will regulate airflow into and out of the fire.

After Cygnus detaches from the station in mid-May, a ground team will turn on power to the Saffire hardware and activate an electronic igniter at one corner of the SIBAL fabric. As the sample burns, instruments will measure temperature, pressure, and concentrations of oxygen and carbon dioxide near the fire. Video cameras will record the shape, growth, and spread of the flames.

The fire should consume the sample fabric and burn itself out in about two hours, but Cygnus will spend another four days in orbit, downlinking to stations on Earth so the researchers can retrieve Saffire’s experimental data before the resupply ship re-enters Earth’s atmosphere and breaks up over the Pacific.

Saffire-II is scheduled to launch on OA-7 in October. With nine smaller samples—including more SIBAL cloth, Nomex, and plexiglass—it will replicate the flammability tests that NASA conducts on Earth. That should help researchers determine how well those tests predict the materials’ flammability in microgravity.

In 2017, Saffire-III will repeat Saffire-I’s large-scale fire, but this time with a stronger airflow. Since airflow is the main factor that influences the size of flames in space, researchers expect to see larger flames in Saffire-III.

The recent BASS-M experiments have helped lay the groundwork for these first three fire experiments, just as they will prepare the way for Saffire-IV through Saffire-VI. These later missions will study how heat and pressure from large fires could affect the rest of the spacecraft cabin, and will give NASA a chance to demonstrate fire suppression technologies that it has spent the last several years developing.

With Mars in Mind, Lockheed Martin Designs Human Habitat to Orbit Moon


Lockheed Martin’s concept of a habitat that could be used during future exploration missions near the moon

As the idea of a human mission to Mars leaps from the pages of science fictionliterature (or off the silver screen) and into reality, NASA is taking a serious look at how astronauts will live, work and survive during the long journey to the red planet.

The federal space agency and its manufacturing partner Lockheed Martin have recently crossed a major milestone in preparation to land the first humans on Marsby completing the pressure module or “backbone” of the vehicle that will take them there—the Orion Crew Module. This spacecraft will launch atop the Space Launch System—the most powerful rocket ever built—and sustain a crew for 21 days as they travel into deep space.

It takes a lot longer than three weeks to get to our neighboring planet so where will astronauts live and work during the rest of the trek through the solar system?Lockheed Martin is in the early stages of providing an answer.

As part of NASA’s NextStep habitat study that is currently underway, Lockheed is one of the four companies conceptualizing an Exploration Augmentation Module or “outpost” that will mate with Orion and sustain a crew for up to 60 days during the first deep space missions leading up to Mars. These outings will see humans travel beyond low-Earth orbit for the first time since 1972 and head toward a destination in cislunar space—a distant orbit around the Moon.

Targeted for the mid 2020s, these exploration missions will see NASA attempt to redirect an asteroid into lunar orbit and eventually study that captured asteroid by rendezvousing with it. A habitat will provide a temporary home for astronauts during these endeavors and will enable them to forge the skills and push the innovations of long-duration spaceflight required to ensure a safe trip for a Mars-bound crew.

Currently, the International Space Station serves as the only scientific laboratory and permanent human outpost in low-Earth orbit. A habitat orbiting the Moon would operate very differently. “The cislunar outpost is actually what we call crew-tended. Crew will not be there year-round like they are on the ISS,” Lockheed Martin’s space exploration architect Josh Hopkins told the Observer. “They will visit for a mission-a-year and that mission could be 30-60 days long.”

One of the major hurdles for a manned mission to Mars is human exposure to space radiation, and this issue will be tackled in cislunar space. The habitat’s initial 60-day limit was established by Lockheed’s team to ensure a safe stay for the crew given this element of radiation. Solar storms and the continuous exposure to cosmic rays are difficult to shield from, but it does become more manageable by limiting the amount of time astronauts spend in deep space. “As we build more knowledge of the biomedical effects and how to protect astronauts, we can start gradually doing longer and longer missions,” explained Hopkins.

As for the random bursts of radiation from a solar storm that could occur, the crew would be able to use the advanced built-in capabilities of Orion, which can act as a storm shelter. In the crew module, the closer an astronaut is to the heat shield, the more protection they have. In order to leverage this capability, they must remove supplies from “locker” spaces behind their seats and actually climb inside.

Protecting humans from radiation on Earth requires shielding from heavy elements like lead but with low-dosage space radiation, lighter materials can do the job. For this reason, Lockheed’s designers are mindful about the placement of consumables and waste products inside the habitat due to these items being a potential source of protection. “What we want are light elements. So things like water, food and plastics tend to be fairly good shielding,” said Hopkins. “We can adjust the locations and positioning of these things we’re going to have in a way that maximizes the amount of protection they give us.”

Along with acting as an emergency radiation storm shelter for the crew, Orion can also provide power, temperature control, and can even recycle air—features than enable a habitat to be low-maintenance and cost-effective.

The crew vehicle can use its propulsion system to provide maneuvering capability for the outpost, but Lockheed’s concept will include on-board, independent propulsion. “You don’t want to return to a habitat that’s tumbling because it wasn’t able to maintain its position in orbit,” said William Pratt, Lockheed’s NextSTEP study manager. “There will be a propulsion stage attached to the habitat and the capability to provide a small amount of power you’ll need when Orion is not there.”

The Orion spacecraft contains advanced capabilities that are unique to long duration deep space missions, enabling a cis-lunar outpost that is less complex and more affordable.

A human habitat or any spacecraft far from Earth will require some degree of autonomy, and this is a specialty for Lockheed Martin’s engineers. Unmanned probes like the MAVEN and the Juno spacecraft that will arrive at Jupiter this summer were both manufactured by Lockheed with autonomous capability. “We feel that’s something we can really bring to a cislunar habitat,” Pratt said. “Our thinking is more about autonomy and giving the crew more autonomy to handle things as they come up at the outpost.”

The primary reason for spacecraft autonomy is communication—or lack thereof. On the long journey to Mars, which could see astronauts spend at least two years aboard a habitat, delays in communication with Earth-based mission control will certainly occur. This could pose a problem when troubleshooting vehicle sub-systems that include life support and oxygen supply.

A major concerned for Lockheed is the long passage of time between the crew’s training and the moment a serious issue does come up during a mission—which could be a few years later. “They may not remember the training. Having the right kind of on-board documentation and flight computer to be able to provide the astronauts the information they need when they need it, is important,” Pratt said. “Not just having the alarm go off but having the alarm go off and the PDF file of the manual come up at the same time. That’s really useful in helping the crew understand how to operate their own vehicle.”

Even though Lockheed Martin’s early habitat concept will service exploration missions near the Moon, the company is always thinking about the manned mission to Mars, which will require a far more advanced successor to their current designs. Engineers will need to go through a few iterations of the concept after the health effects of long-duration human spaceflight are known and as new technology is developed. This is the basis that NASA created NextSTEP on.

The federal space agency is looking for a modular habitat that can grow, evolve and be added to. “New modules are built upon the lessons of the previous modules,” Hopkins said.
