The lifting body vehicle will be launched on a United Launch Alliance (ULA) Atlas V rocket and will have the ability to return—along with cargo—by landing at any available airport. SNC’s Dream Chaser is made of non-toxic materials meaning it can touch down on commercial runways and be accessed immediately.

The chance to showcase a reusable spacecraft on government funded missions bodes well for a potential pivot to commercial use. SNC is at the leading edge of private space companies that one day might cater to a more diverse base of consumers like universities, medical companies and individuals.

To learn more about Dream Chaser’s history and development, we spoke to John Roth, Vice President of Business Development for SNC’s Space Systems.

Transport Quantum bits via superconducting nanowires. Definite step forward in information transmittal capabilities.

Although 74 picoseconds may not sound like much — a picosecond is a trillionth of a second — it is a big deal in the quantum world, where light particles, or photons, can carry valuable information. In this case it means that much less “jitter,” or uncertainty in the arrival time of a photon. Less jitter means that photons can be spaced more closely together but still be correctly detected. This enables communications at a higher bit rate, with more information transmitted in the same period.

Every little bit helps when trying to receive faint signals reliably. It helped, for example, in NIST’s recent quantum teleportation record and difficult tests of physics theories. In such experiments, researchers want to decode as much information as possible from the quantum properties of billions of photons, or determine if “entangled” photons have properties that are linked before — or only after — being measured.

A new form of matter, in which electrical charge swirls in “polar vortices,” has been observed in a ferroelectric material.

Notably, ferroelectric materials display unique electrical or magnetic properties, as such, the discovery holds intriguing possibilities for advanced kinds of memory and processors that take up far less space, and could also “rewrite our basic understanding of ferroelectrics,” according to the researchers who observed them.

Researchers have successfully demonstrated how it is possible to interface graphene — a two-dimensional form of carbon — with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as epilepsy or Parkinson’s disease.

Humans have contributed, in the form of plastic, glass, and purified metals, the largest influx of new minerals into Earth’s geologic history (probably) since oxygen levels first ticked up in the atmosphere around 2.3 billion years ago.

Here’s two new, 100% real science words for you to learn today: Technofossil and plastiglomerate.

I’ll have a video out about this on Feb. 8… stay tuned!

Space is not a government program; it’s the rest of the Universe. Private space business is now a major factor, bent on finding investors interested in generating profits by making space more accessible to more people. Space business pays taxes to governments; it does not consume tax revenues. Further, space business can offer launch services to government agencies at highly competitive rates, thus saving taxpayer dollars. How can they do this, competing with government-funded boosters with a 50-year track record? Simple: governments have no incentive to cut costs. Traditional aerospace industry giants have a huge vested interest in boosters that were developed to military and NASA standards, among which economy was not even an issue. But innovative, competitive companies such as XCOR Aerospace and Mojave Aerospace, without such baggage (and overhead) can drive costs down dramatically. This is a proven principle: notice that we are no longer buying IBM PCs with 64 k of RAM for $5000 a unit.

Even more important in the long view, space is a literally astronomical reservoir of material and energy resources. The profit potential of even a single such resource, such as solar power collectors in space beaming microwave power to Earth, is in the trillions of dollars. What would it be worth to the world to reduce fossil fuel consumption by a factor of 20 or 100 while lowering energy costs? Can we afford to continue pretending that Earth is a closed system, doomed to eke out finite resources into a cold, dark future?

Can we afford space? Wrong question. Can businesses afford space? Yes. We get to reap the benefits of their innovative ideas and free competition without footing the bill.

Glad to see The Martian get some Academy Award action; as much as I liked the novel, I found the film to be as good or better, which is rare. And I also found it to be personally inspiring in a way that few science fiction films are. But the point I’m trying to make here is that; we aren’t that far from Hermes-type spacecraft for interplanetary transfer. It’s not out of the realm of possibilities. I wonder if any of you feel the same way.

With six Academy Award nominations, the celebrated film adaptation of Andy Weir’s novel “The Martian” has been the perfect tonic for rousing interest in human missions to Mars.

But as good as the book truly is, the film transcends its source material about a stranded Mars astronaut with some practical takeaways that are as inspiring as any out there. They include:

String theory is the leading candidate for a “theory of everything” — and Subir Sachdev is taking the “everything” part literally. In a conversation with Quanta Magazine, Sachdev explains how he’s taking inspiration from the mathematics of string theory to learn more about the behavior of high-temperature superconductors.

A new type of glass to reducing electric bills.

A revolutionary new type of smart window developed by the University College London (UCL) and the Engineering and Physical Sciences Research Council (EPSRC) could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Partially inspired by the reflective properties of moth eyes, this smart window is said to be self-cleaning, energy saving, and anti-glare.

When rain hits the outside of the smart window it forms spherical droplets that roll over the surface and pick up dirt, dust and other contaminants, then carries them away. This can either eliminate or reduce the need for manual cleaning.
