The following declassified nuclear test footage has been enhanced using AI with techniques such as slow motion, frame interpolation, upscaling, and colorization. This helps improve the clarity and visual quality of the original recordings, which were often degraded or limited by the technology of the time. Experiencing these shots with enhanced detail brings the devastating power of atomic weapons into focus and offers a clearer perspective on their catastrophic potential and impact.

ARLINGTON, Va. — Two SpaceX-built satellites successfully exchanged data using optical communications terminals in a milestone for the U.S. Space Development Agency (SDA), the agency’s director Derek Tournear said Sept. 4.

The satellites, part of SDA’s Tranche 0 experimental spacecraft in low Earth orbit, used laser terminals manufactured by Tesat-Spacecom to communicate. This marks the first time the agency has demonstrated laser communications in space using optical terminals compliant with military standards required for SDA satellites.

“We had not previously demonstrated laser communications,” Tournear said at a DefenseNews conference. He reported that the data exchange occurred on September 3, with the satellites establishing a connection in under 100 seconds and maintaining it for several hours.

Widely utilized across various industries such as chemistry, agriculture, and military, this technology relies on strategies like dispersive optics and narrow-band light filters.

However, limitations exist in these approaches. Additionally, the fabrication of large-scale InGaAs detector arrays poses challenges, necessitating the development of new experimental methods and algorithms to advance infrared hyperspectral imaging technology in terms of miniaturization and cost-effectiveness.

In a paper published in Light Science & Applications, a team led by Professor Baoqing Sun and Yuan Gao from Shandong University introduce a novel method for encoding near-infrared spectral and spatial data.

WASHINGTON — General Dynamics Mission Systems, a unit of defense contractor General Dynamics, has been awarded a $491 million contract extension by the Space Development Agency for satellite ground systems, the Pentagon announced Aug. 30.

The modification nearly doubles the company’s existing contract with the Space Development Agency (SDA) to approximately $900 million through 2029. General Dynamics in 2022 was selected to build the ground operations and integration segment for the SDA’s Proliferated Warfighter Space Architecture (PWSA), a mesh network of satellites in low Earth orbit designed to support global military operations.

SDA. which is under the U.S. Space Force, is building the PWSA with a dedicated tracking layer that allows for real-time detection and monitoring of ballistic missile threats. The PWSA also is intended to provide a low-latency communication backbone for continuous data transmission, enhancing the ability to coordinate joint operations across different military branches.

During the Cold War Era of the 1960s, Russian researchers were looking for ways to support the immune system in conditions running the gamut from cancer to bio-warfare agents. Eastern Europeans, with a cultural love of fermented milk products, logically looked to probiotics, or lactobacillus, for immune support because it was safe, cheap and effective.

A Bulgarian researcher and medical doctor, Dr. Ivan Bogdanov, researched lactobacillus bacteria in the 1960s. Bogdanov believed that specific strains of probiotics could have anti-tumor properties.

The doctor’s research team injected mice with a sarcoma cancer, then administered a crude mixture of cell fragments from a strain of Lactobacillus delbrukii. Bogdanov observed that the cancer disappeared within a few days. Subsequently, researchers attempted to re-grow cancer in the same mice, but without success — the mice seemed immune to the cancer cells.

WASHINGTON — The Space Development Agency awarded contracts to Terran Orbital and York Space Systems to build and operate 10 satellites each for the military’s low Earth orbit communications network, the agency announced Aug. 16.

The contracts, valued at $254 million for Terran Orbital and $170 million for York Space, are for the final 20 satellites of SDA’s Tranche 2 Transport Layer Gamma program. Delivery is expected in the fourth quarter of fiscal year 2027.

These satellites will form part of the Proliferated Warfighter Space Architecture, a constellation of data relay and sensor satellites designed to provide global communications and missile detection capabilities.
