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.

Nearly 200 DeepMind workers signed a letter urging Google to drop military contracts, fearing AI misuse and violations of the company’s own rules.

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.

The Maven and Collaborative Combat Aircraft efforts display real steps forward, a pair of reports say.

“We see significant progress,” in opening up DOD data, one observer said. But a bigger, multinational test is coming.

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.

WASHINGTON — Aerospace and defense contractor Sierra Nevada Corporation (SNC) is set to expand its radio frequency (RF) satellite constellation, aiming to capture a larger share of the market for electronic emissions data.

The company launched its first four RF sensing cubesats last year, built by Spire, marking its entry into this increasingly competitive field. SNC is now gearing up for a significant expansion, with plans to deploy a network of 20 satellites over the next five years.

Chris Morgan, SNC’s vice president, told SpaceNews the company sees a rising demand in the military sector for RF data, which can provide critical intelligence on activities like GPS jamming and enemy movements. The RF sensing market, he said, is also driven by commercial applications.
