It’s all thanks to nanoclusters.

A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronicsAn improved lightweight, a protective lattice that can absorb twice as much energy as previous materials of a similar density has been developed by engineers for nanoscale 3D printing.

According to the study led by Stanford University, a nanoscale 3D printing material, which creates structures that are a fraction of the width of a human hair, will enable to print of materials that are available for use, especially when printing at very small scales.

The spacecraft successfully enters lunar orbit.

A toaster oven-sized NASA spacecraft will pave the way for a lunar orbital station that will help the U.S. space agency establish a permanent presence on the moon.

CAPSTONE, the first cubesat mission to ever visit the moon, was launched from New Zealand by a Rocket Lab Electron rocket on June 28 and it was designed to test the stability of the orbit NASA intends to use for its lunar Gateway orbital outpost.

NASA announced in a blog update that its 55-pound (25-kilogram) CAPSTONE cubesat spacecraft successfully inserted itself into orbit around the moon on Sunday, November 13.

On the morning of November 10, an Atlas V rocket launched JPSS-2, NOAA’s newest environmental satellite into orbit. Hitching a ride on the rocket was NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”

Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth.

A sub-type of GRB known as a short-duration GRB starts life when two neutron stars collide. These ultra-dense stars have the mass of our sun compressed down to half the size of a city like London, and in the final moments of their life, just before triggering a GRB, they generate ripples in space-time—known to astronomers as gravitational waves.

Until now, space scientists have largely agreed that the “engine” powering such energetic and short-lived bursts must always come from a newly formed black hole (a region of where gravity is so strong that nothing, not even light, can escape from it). However, new research by an international team of astrophysicists, led by Dr. Nuria Jordana-Mitjans at the University of Bath, is challenging this scientific orthodoxy.

Arthur C. Clarke, science fiction author and futurist, crossed paths with the scientists of the Bell System on numerous occasions. In 1945, he concurrently, but independently, conceived of the first concept for a communications satellite at the same time as Bell Labs scientist, John Robinson Pierce too, was a science fiction writer. To avoid any conflict with his day job at Bell Labs, Pierce published his stories under the pseudonym J.J. Coupling.

In the early 1960s, Clarke visited Pierce at Bell Labs. During his visit, Clarke saw and heard the voice synthesis experiments going on at the labs by John L. Kelly and Max Mathews, including Mathews’ computer vocal version of “Bicycle Built for Two”. Clarke later incorporated this singing computer into the climactic scene in the screenplay for the movie 2001: A Space Odyssey, where the computer HAL9000 sings the same song. According to Bob Lucky, another Bell Labs scientist, on the same visit, Clarke also saw an early Picturephone, and incorporated that into 2001 as well.

In 1976, AT&T and MIT held a conference on futurism and technology, attended by scientists, theorists, academics and futurists. This interview with Clarke during this conference is remarkably prescient—especially about the evolution of communications systems for the next 30+ years.

The interview was conducted for an episode of a Bell System newsmagazine, but this is the raw interview footage.

A series of demonstrations by Micius—a low-orbit satellite with quantum capabilities—lays the groundwork for a satellite-based quantum communication network.

Few things have captured the scientific imagination quite like the vastness of space and the promise of quantum technology. Micius—the Chinese Academy of Science’s quantum communications satellite launched in 2016—has connected these two inspiring domains, producing a string of exciting first demonstrations in quantum space communications. Reviewing the efforts leading up to the satellite launch and the major outcomes of the mission, Jian-Wei Pan and colleagues at the University of Science and Technology of China provide a perspective on what the future of quantum space communications may look like [1]. The success of this quantum-satellite mission proves the viability of several space-based quantum communications protocols, providing a solid foundation for future improvements that may lead to an Earth-spanning quantum communications network (Fig. 1).

Photons, the quanta of light, are wonderful carriers of quantum information because they are easy to manipulate and travel extremely fast. They can be created in a desired quantum state or as the output of some quantum sensor or quantum computer. Quantum entanglement between multiple photons—the nonclassical correlation between their quantum states—can be amazingly useful in quantum communications protocols such as quantum key distribution (QKD), a cryptography approach that can theoretically guarantee absolute information security. QKD schemes have been demonstrated on distances of a few hundreds of kilometers—sufficient to cover communications networks between cities. But increasing their range, eventually to the global scale, is a formidable challenge.

A century after Albert Einstein came up with his theories of relativity, a constellation of Global Positioning System satellites is orbiting Earth, making practical use of his ground-breaking understanding of time.

If the discovery of the Higgs boson particle pans out, will even more mind-bending technologies result?

Theoretically, it’s possible, says Arizona State University physicist Lawrence Krauss; but practically, it’s unlikely.

From swerving to sheltering in place, here’s how the International Space Station handles hazards on the increasingly cluttered space lanes.

The most recent maneuver happened last week when the ISS boosted itself into a higher orbit to avoid debris from a 2021 Russian anti-satellite missile test. It’s likely that such close calls will only get more common as humanity keeps cluttering up the space lanes with old satellites and bits of wreckage from collisions and missile tests. Here’s what you need to know about space debris and how to avoid it.

How does the International Space Station dodge space debris?

It’s tempting to picture astronauts piloting the ISS like it’s the Millennium Falcon, relying on their lightning reflexes (and maybe the Force) to swerve around bits of obliterated spaceships, often with mere inches to spare. The reality — like a lot of things in space flight — is much slower and happens over much bigger distances than Hollywood’s version. But it can still be extremely tense, as lives are at stake, and if something goes wrong, help is not on the way.
