Injecting Gases Into The Stratosphere Could Reduce Hurricanes

In an attempt to combat climate change, a multinational team of scientists are studying how shading sulfate aerosols that are dispersed into the stratosphere could help cool the planet and reduce the number of hurricane occurrences. “We’re basically mimicking a volcano and saying we’re going to put 5 billion tons of sulfates a year into the atmosphere 20 kilometers high, and we’ll do that for 50 years,” says John Moore, head of China’s geoengineering research program

Io over Jupiter from Voyager 1 

Back in 1979, NASA’s Voyager 1 spacecraft flew past Jupiter and its moons. The images in this mosaic, featuring the moon Io against a background of gas giant Jupiter’s diffuse swirling cloud bands, were recorded by Voyager’s camera from a distance of about 8.3 million kilometers. The Io image from this mosaic may be the first to show curious round features on Io’s surface with dark centers and bright rims more than 60 kilometers across. Now known to be volcanic in origin, these features were then thought likely to be impact craters, commonly seen on rocky bodies throughout the Solar System. But as Voyager continued to approach Io, close-up pictures revealed a bizarre world devoid of impact craters, frequently resurfaced by volcanic activity. Earlier this year a new robotic spacecraft, NASA’s Juno, began to orbit Jupiter and last week made a pass within 5,000 kilometers of Jupiter’s clouds. During the next two years, it is hoped that Juno will discover new things about Jupiter, for example what’s in Jupiter’s core.

An amateur astronomer discovered a new exploding star on Christmas Day

Although no three kings were present at the time, amateur astronomer Emmanuel Conseil discovered a 'new star' or nova in the Triangulum Galaxy on Christmas Day. He made the discovery using the online Slooh observatory, whose telescopes are located...

What a way to spend Christmas!

This is the follow-up to squine and cosquine, and I find students find it really cool. Are there any other shapes someone has done this for?

Hitchhiking a Ride to Space

Have you ever packed for a long trip with a friend and ran out of space in your suitcase? Maybe your friend was nice and let your spare items hitchhike a ride in their bag?  The following science experiments are doing something similar on our Space Launch System rocket.

Our Space Launch System (SLS) will be the most powerful rocket we’ve ever built and will enable astronauts in the Orion spacecraft to travel deeper into the solar system. This advanced launch vehicle will launch astronauts to an asteroid and eventually to Mars, while opening new possibilities for other payloads including robotic scientific missions to places like Mars, Saturn and Jupiter.

The primary goal of SLS and the Orion spacecraft is to launch future crewed, deep space missions. That said, an added bonus of this powerful rocket is the extra science it can carry. On it’s first mission (known as Exploration Mission-1, EM-1) SLS will carry 13 CubeSats (small satellites, each the size of a large shoebox) on its first flight as secondary payloads. These small satellites will perform various in-space experiments. In a way, these 13 CubeSats are ‘space hitchhikers’, catching a ride to deep space where they can gather data valuable to future exploration missions.

How were these 13 experiments selected? Great question. They were selected through a series of announcements of flight opportunities, a public contest and negations with our international partners.

These secondary payloads have a vast array of functions, from taking pictures of asteroids, to using yeast to detect impacts of deep-space radiation. Each month we will highlight one of these experiments on Tumblr and talk about all the exciting science they will do. Just to give you an idea of what these shoebox-sized satellites will do, we’ll give you a preview:

1. NEA Scout

NEA Scout, stands for: Near-Earth Asteroid Scout. This CubeSat will investigate an asteroid, taking pictures and observe its position in space.

2. BioSentinel

BioSentinel will be the first time living organisms have traveled to deep space in more than 40 years. It will use yeast to detect, measure and compare the impact of deep-space radiation on living organisms over long durations in deep space.

3. Lunar Flashlight

This experiment will look for ice deposits and identify locations where resources may be extracted from the lunar surface. It will demonstrate the capability to scout for useful materials and resources from lunar orbit.

4. Skyfire

Lockheed Martin’s Skyfire will perform a lunar flyby, collecting data to address both Moon and Mars Strategic Knowledge Gaps, or gaps in information required to reduce risk, increase effectiveness and improve the design of robotic and human space exploration missions, for surface characterization, remote sensing and site selection.

5. Lunar IceCube

Morehead State University’s Lunar IceCube will look for water in ice, liquid and vapor forms from a very low orbit of only 62 miles above the surface of the moon. The ability to search for useful resources can potentially help astronauts manufacture fuel and necessities to sustain a crew.

6. CuSP

The CubeSat mission to study Solar Particles, or CuSP, will be the first protype of an interplanetary CubeSat space weather station. It will observe space weather events hours before they reach Earth.

7. Luna-H-Map

Lunar Polar Hydrogen Mapper (LunaH) will enter a polar orbit around the moon with a low altitude. From there, it will produce maps of near-surface hydrogen.

8, 9, 10. Three Tournament Payloads

Three of the payloads riding along on this journey will be the winners of the Ground Tournaments portion of our CubeQuest Challenge. This challenge is designed to foster innovation in small spacecraft propulsion and communications techniques. Learn more about this challenge HERE.

11, 12, 13. International Partners

The remaining three payloads are reserved for international partners, and will be announced at a later time.

Researchers Discover Ultra-thin Diamond Nanothreads That Could Support Space Elevator

Today, in order to get to the Moon, an incredible logistical setup is required. From the training needed for astronauts, to the millions of dollars of equipment necessary for space travel, to the cost of rocket fuel—Space flight isn’t easy (or cheap). But what if one can reach the Moon by simply stepping into a small vehicle attached to a cable and pressing a button that says “Moon.”

If what you’re imagining is an elevator, then you are right.

It’s also an idea that several scientists have been trying to realize since 1895, and we have written a number of articles on the feasibility of this tech in the past. Now, with what researchers from the Pennsylvania State University discovered, we may be taking a step closer to achieving that idea.

When they applied alternating cycles of pressure to isolated, liquid-state benzene molecules, surprisingly, it was found that rings of carbon atoms assembled into neat and orderly chains, essentially forming strong ultra-thin diamond nanothreads.

Wow. NASA has released some amazing images of Saturn’s icy moon Enceladus.

Physicists Predict The Existence of New Particle in the “Material Universe”

Scientists are predicting the existence of the type-II Weyl fermion. This comes after they realized that a metallic crystal material, called tungsten ditelluride, was exhibiting a strange behavior. While most metals turn into insulators once subjected to a magnetic field, tungsten ditelluride becomes either an insulator or a conductor, which one it becomes ultimately depends on the direction of the subjected magnetic field.

After a team investigated the phenomenon, they predicted the presence of an unexpected particle—the previously mentioned type-II Weyl fermion—which caused the behavior.
