WASHINGTON — The Space Development Agency confirmed on Jan. 8 that it awarded Rocket Lab a $515 million contract to build and operate 18 spacecraft that will be part of a low Earth orbit network of military satellites.

SpaceNews first reported on this contract award on Dec. 23 after the agreement was disclosed in a regulatory filing.

Rocket Lab becomes the third supplier of SDA’s Transport Layer Tranche 2 Beta satellites — projected to launch in mid-2027 — that will carry radios using the UHF (Ultra High Frequency) and S-band frequencies that military and intelligence units rely upon for voice and low-speed data transmissions.

WASHINGTON — The U.S. Space Force has inked a $19.8 million deal with Microsoft to develop a virtual and mixed-reality training environment. This agreement positions the tech giant in the burgeoning military simulation market and expands its Azure cloud’s reach into space applications.

The one-year contract announced Jan. 5 is to continue work on an augmented reality space simulation tool that Microsoft started developing last year for the Space Systems Command in Los Angeles.

Dubbed the Integrated, Immersive, Intelligent Environment (I3E), the system features Microsoft’s HoloLens headsets, Azure cloud platform, and a mesh framework for building shared AR experiences. Together, these technologies enable an interactive model of space with accurately scaled orbital objects that users can manipulate in real time.

WASHINGTON — The startup Muon Space announced Jan. 9 it will explore the use of climate-monitoring satellites to capture cloud characterization data for the U.S. Air Force.

The Mountain View, California-based company, founded in 2021, is developing small satellites to monitor Earth’s climate and ecosystems.

Under a Small Business Innovation Research Phase 1 contract from the U.S. Air Force, Muon Space “will perform a feasibility study to determine the benefit of modifying its multispectral electro-optical infrared (EO/IR) instrument to support the Department of Defense’s cloud characterization observation capability,” the company said.

HELSINKI — China launched its Einstein Probe early Tuesday to detect X-ray emissions from violent, fleeting cosmic phenomena using novel lobster eye-inspired optics.

A Long March 2C rocket lifted off from Xichang Satellite Launch Center in southwestern China at 2:03 a.m. (0703 UTC), Jan. 9. The China Aerospace Science and Technology Corp. (CASC) confirmed launch success within the hour.

The Einstein Probe (EP) is part of growing Chinese strategic space science efforts. The spacecraft will spend at least three years observing distant, violent interactions such as tidal disruption events—in which stars are pulled apart by supermassive black holes—supernovae, and detect and localize the high-energy, electromagnetic counterparts to gravitational wave events.

Recent theoretical work has identified the possibility of a new and fundamental form of magnetism.

Collinear magnetism, where magnetic moments of all ions are parallel or antiparallel to each other, is a century-old concept in condensed-matter physics. In the past two decades, researchers began exploring the exotic world of noncollinear magnets, which include spin spirals, skyrmions, spin ices, and more. But more recently a fundamentally new form of collinear magnetism has emerged: altermagnetism. Like ferromagnetism, it breaks time-reversal symmetry and harbors anomalous transport properties, such as the anomalous Hall effect and magneto-optics. Like antiferromagnetism, it has, by symmetry, no net magnetization. The phenomenon was identified between 2019 and 2021 by four different groups [1–4]. In 2022, Libor Šmejkal of Johannes Gutenberg University Mainz in Germany and colleagues named it altermagnetism [5]. Despite its youth, altermagnetism is already proving a fertile field for theory and for proposed applications.

Using a soap bubble, researchers have created a laser that could act as a sensitive sensor for environmental parameters including atmospheric pressure.

Soap bubbles are known for their attention-grabbing effect on toddlers, and now researchers have shown that these objects have another dazzling use—generating color-tunable laser light [1]. They demonstrated that a dye dissolved in the soap solution of such a bubble can amplify light circulating in the spherical shell and produce laser light. This light is visible as a glowing ring around the bubble. Such “bubble lasers” could act as precision sensors for measuring atmospheric pressure or for detecting changes in an electric field.

The allure of bubbles comes in large part from their interaction with light. As soap bubbles dance through the air, they sparkle like glitter, shifting hues as they move. This phenomenon, known as iridescence, comes from the interference of light waves within a bubble’s soapy shell.

Nube is an almost invisible dwarf galaxy discovered by an international research team led by the Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of La Laguna (ULL) and other institutions.

The name was suggested by the 5-year-old daughter of one of the researchers in the group and is due to the diffuse appearance of the object. Its surface brightness is to faint that it had passed unnoticed in the various previous surveys of this part of the sky due to the object’s diffuse appearance as if it were some kind of ghost. This is because its stars are so spread out in such a large volume that “Nube” (Spanish for “Cloud”) was almost undetectable.

This newly discovered galaxy has a set of specific properties which distinguish it from previously known objects. The research team estimate that Nube is a 10 times fainter than others of its type, but also 10 times more extended than other objects with a comparable number of stars.

A crippling fuel leak forced a U.S. company on Tuesday to give up on landing a spacecraft on the moon.

Astrobotic Technology’s lander began losing fuel soon after Monday’s launch. The spacecraft also encountered problems keeping its solar panel pointed towards the sun and generating .

“Given the propellant leak, there is, unfortunately, no chance of a soft landing on the moon,” Astrobotic said in a statement.

A new study in Physical Review Letters illuminates the intricacies of energy exchanges within bipartite quantum systems, offering profound insights into quantum coherence, pure dephasing effects, and the potential impact on future quantum technologies.

In quantum systems, the behavior of particles and are governed by probability distributions and wave functions, adding layers of complexity to the understanding of energy exchanges.

The exploration of energy exchanges in quantum systems inherently involves tackling the complexities arising from and the scales at which quantum systems operate, introducing sensitivity.
