Orbex lands TriSept as a customer for rideshare rocket launch mission in 2022

Posted by in categories: 3D printing, government, space

Space launch startup Orbex has secured a customer for its forthcoming Prime space launch vehicle: TriSept, a provider of launch integration services for both commercial and government customers. TriSept has booked the full capacity of a rideshare mission aboard an Orbex Prime rocket to take off sometime in 2022, which should work schedule-wise, provided Orbex meets its target of flying its initial missions starting next year.

Orbex is leaning on 3D printing to expedite its launch vehicle production process, while also keeping costs low. The U.K.-based company is also in the process of working on final approvals and construction of a new spaceport in Sutherland, located in the Scottish highlands, which, when complete, will be the first mainland space launch facility in Europe.

TriSept, which provides launch management and brokerage services in addition to integration for payloads loaded into the launch vehicle, has been operating in the U.S. space market for years now, and it’ll also be setting up a full-time presence in the U.K. ahead of the Sutherland spaceport’s opening later this year, at Harwell Space Campus in Oxford.

Hyperuniform disordered waveguides and devices for near infrared silicon photonics

Posted by in categories: chemistry, internet, physics, robotics/AI, space

In a new report published on Scientific Reports, Milan M. Milošević and an international research team at the Zepler Institute for Photonics and Nanoelectronics, Etaphase Incorporated and the Departments of Chemistry, Physics and Astronomy, in the U.S. and the U.K. Introduced a hyperuniform-disordered platform to realize near-infrared (NIR) photonic devices to create, detect and manipulate light. They built the device on a silicon-on-insulator (SOI) platform to demonstrate the functionality of the structures in a flexible, silicon-integrated circuit unconstrained by crystalline symmetries. The scientists reported results for passive device elements, including waveguides and resonators seamlessly integrated with conventional silicon-on-insulator strip waveguides and vertical couplers. The hyperuniform-disordered platform improved compactness and enhanced energy efficiency as well as temperature stability, compared to silicon photonic devices fabricated on rib and strip waveguides.

Academic and commercial efforts worldwide in the field of silicon photonics have led to engineer optical data communications at the Terabit-scale at increasingly lower costs to meet the rapidly growing demand in data centers. Explosive growth in cloud computing and entertainment-on-demand pose increasingly challenging costs and energy requirements for , processing and storage. Optical interconnects can replace traditional copper-based solutions to offer steadily increasing potential to minimize latency and , while maximizing the bandwidth and reliability of the devices. Silicon photonics also leverage large-scale, complementary metal-oxide semiconductor (CMOS) manufacturing processes to produce high-performance optical transceivers with high yield at low-cost. The properties allow applications of optical transceivers (fiber optical technology to send and receive data) to be increasingly compelling across shorter distances.

More than three decades ago, physicist Richard Soref identified silicon as a promising material for photonic integration. Leading to the present-day steady development and rapid production of increasingly complex photonic integrated circuits (PICs). Researchers can integrate large numbers of massively-parallel compact energy-efficient optical components on a single chip for cloud computing applications from deep learning to artificial intelligence and the internet of things. Compared to the limited scope of commercial silicon photonic systems, photonic crystal (PhC) architectures promise smaller device sizes, although they are withheld by layout constraints imposed by waveguide requirements along the photonic crystal’s axis. Until recently, photonic band gap (PBG) structures that efficiently guide light were limited to photonic crystal platforms. Now, newer classes of PBG structures include photonic quasicrystals, hyperuniform disordered solids (HUDs) and local self-uniform structures.

Breathtaking Image Shows Powerful Magnetic ‘Ropes’ Surrounding The Whale Galaxy

Posted by in category: space

Sometimes you just have to stand back in awe at the beauty of the Universe – and that’s absolutely the case with this image from the National Radio Astronomy Observatory (NRAO), which captures the side view of a spiral galaxy know as the Whale Galaxy.

But if you look closer, the stunning picture also shows something else: the magnetic ‘ropes’ around the edges of the galaxy’s disc.

These filaments, like cosmic strands of hair, show the galaxy’s magnetic field extending into its halo.

Mars’s Water Is Evaporating Away Even Faster Than We Expected

Posted by in categories: particle physics, space

Billions of years ago, Mars could have been a planet very like Earth with copious liquid water on its surface. But over time, that water rose into Mars’s thin atmosphere and evaporated off into space. There are only very small amounts of water vapor left in the atmosphere today, and a new study shows that vapor is being lost even faster than previously believed.

The research, published in the journal Science, used data from the Trace Gas Orbiter in orbit around Mars to see how water moved up and down through the layers of the Martian atmosphere in order to understand how fast it evaporates away. They found that the vapor changes through the seasons and that in the warmer months the atmosphere hosts a whole lot more water than expected, in a state called “supersaturation.”

When the atmosphere becomes supersaturated, this makes the evaporation of water happen even faster. “Unconstrained by saturation, the water vapor globally penetrates through the cloud level, regardless of the dust distribution, facilitating the loss of water to space,” the authors explain. Even when the density of dust or ice particles in the atmosphere changes, that still doesn’t stop supersaturation, so the evaporation of water continues at a brisk pace.

‘There’s something here’: teen discovers new planet while interning at NASA

Posted by in category: space

Assigned to study how two stars would cross paths creating an eclipse, he focused on the solar system TOI 1338, where he noticed something in the orbit of two stars that was blocking the light.

His bosses spent several weeks verifying his observation, and ultimately concluded that Cukier had discovered a planet 6.9 times larger than Earth and only the 13th planet of its kind ever discovered.

“I was looking through the data for everything the volunteers had flagged as an eclipsing binary, a system where two stars circle around each other and from our view eclipse each other every orbit,” Cukier said, according to a NASA press release.

By Donna Lu

A trippy maths program that visualises the inside of strange 3D spaces could help us figure out the shape of the universe.

Henry Segerman at Oklahoma State University and his colleagues have been working to interactively map the inside of mathematical spaces known as 3-manifolds using a program called SnapPy.

Remembering Stephen Hawking on his 78th birthday: A legacy of humanity

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

Stephen Hawking passed away on 14 March 2018. His work changed literally everything we know about the cosmos and our place in it. But his greatest contribution to our species wasn’t his theories on black holes or how quickly the universe was expanding, it was his humanity.

Professor Hawking was born on 8 January 1942. He would have been 78 years old today – a bit older than ‘boomer’ age, his generation was called the “Silent” one. In his early twenties he was diagnosed with Lou Gehrig’s disease (ALS). Eventually he became paralyzed and could only speak with the assistance a computer-generated audio device.

Building in Space: Using Maxar’s Robotics to Enable Sustainable Space Operations

Posted by in categories: robotics/AI, space, sustainability

Combining Maxar’s capabilities in robotics, spacecraft and space systems operations creates the opportunity to deploy and maintain revolutionary new space architectures. Since the dawn of space exploration, pioneers in the field envisioned sustainable space stations enabled by in-space assembly, manufacturing and servicing. Wernher Von Braun conducted a detailed study in 1945 that defined the deployment and construction of the rotating wheel space station. The design included maintaining artificial gravity and oxygen levels. Today, NASA has led the construction and continuous operation of the International Space Station for over 20 years, demonstrating the technical feasibility of large-scale in-space assembly and servicing.

Recently, Maxar has been working with NASA on concepts for both human-tended and uncrewed sustainable space platforms. These in-space assembled structures provide basic functions and a modular interface for new and evolving payloads and missions. The lunar orbiting Gateway will be one such platform where the Maxar-developed Power and Propulsion Element will provide the foundation of power, maneuvering, communications systems and initial docking capabilities. Additional Gateway segments will plug-in to the Power and Propulsion Element to make use of these systems. The versatility of the Power and Propulsion Element also allows it to be refueled in orbit, and we are working with NASA to conceive the architecture that could resupply the Gateway with fuel and other essentials.
