The US military’s AI experiments are growing particularly ambitious. The Drive reports that US Northern Command recently completed a string of tests for Global Information Dominance Experiments (GIDE), a combination of AI, cloud computing and sensors that could give the Pentagon the ability to predict events “days in advance,” according to Command leader General Glen VanHerck. It’s not as mystical as it sounds, but it could lead to a major change in military and government operations.

The machine learning-based system observes changes in raw, real-time data that hint at possible trouble. If satellite imagery shows signs that a rival nation’s submarine is preparing to leave port, for instance, the AI could flag that mobilization knowing the vessel will likely leave soon. Military analysts can take hours or even days to comb through this information — GIDE technology could send an alert within “seconds,” VanHerck said.

The most recent dry run, GIDE 3, was the most expansive yet. It saw all 11 US commands and the broader Defense Department use a mix of military and civilian sensors to address scenarios where “contested logistics” (such as communications in the Panama Canal) might pose a problem. The technology involved wasn’t strictly new, the General said, but the military “stitched everything together.”

Launching satellites is an expensive business — at least for now. But satellites are necessary in astronomy for one major reason — they get telescopes above the atmosphere.

Google uses artificial intelligence technology to find millions of buildings on the satellite map that were previously difficult to locate. These can now be used for humanitarian aid or other purposes. Google utilized its building detection model (Continental-Scale Building Detection from High Resolution Satellite Imagery) to create an Open Buildings dataset, containing locations and footprints of 516 million buildings with coverage across most African continent countries.

In this data set, there are millions of buildings that have not been discovered in the past. These newly-discovered building materials will help the outside world understand African populations and where they live, facilitating health care services such as education or vaccination to their communities.

Google’s team of developers built a training set for their building detection model by manually labeling 1.75 million buildings in 100k images to make the most accurate identification possible, even when dealing with rural or urban environments that have vastly different properties and features. The need to identify what kind of dwelling place is being captured was especially difficult during scoping missions in remote areas where natural landmarks were plentiful. At the same time, dense surroundings made it hard to differentiate between multiple structures on an aerial image at once.

The world’s first commercial fully re-programmable satellite lifted off from French Guiana on Friday on board an Ariane 5 rocket, ushering in a new era of more flexible communications.

Unlike conventional models that are designed and “hard-wired” on Earth and cannot be repurposed once in orbit, the Eutelsat Quantum allows users to tailor the communications to their needs—almost in .

The satellite will be placed in orbit some 36 minutes after the launch.

AFRL completed a two-year space experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.

WASHINGTON — The U.S. Air Force Research Laboratory announced July 19 it has completed a two-year experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.

Known as the Demonstration and Science Experiments (DSX) mission, the spacecraft was one of 24 payloads launched June 25, 2019, on a SpaceX Falcon Heavy rideshare.

AFRL had spent 16 years developing and testing DSX. The mission was to study the harsh radiation environment of medium orbits — from about 2000 to 35000 kilometers above Earth — where the Defense Department operates critical spacecraft like the Global Positioning System.

Now, in what would be the biggest international step yet towards addressing these concerns, diplomats at a United Nations forum next month might discuss whether humanity has a right to ‘dark and quiet skies’. The debate could initiate a framework for how scientists and the public would deal with the flood of new satellites — with many more expected.

Working with the United Nations, scientists hope to establish standards for satellite ‘megaconstellations’ and reduce disruption of astronomical observations.

Amazon acquires Facebook’s Satellite Internet team!

Project Kuiper going strong to compete SpaceX’s StarLink, OneWeb and Telesat.

The deal bolsters Amazon’s $10 billion effort to develop low Earth orbit (LEO) satellites capable of delivering high-speed broadband internet around the globe, while marking the end of Facebook’s ultimately unsuccessful efforts to do the same.

Facebook’s team, which joined Amazon’s existing 500-person operation in April, included physicists as well as hardware and software engineers who have experience working on aeronautical and wireless systems, according to The Information.

The talent acquisition deal included some intellectual property developed by the team, as well as equipment and facilities, Facebook told Insider. Other terms were not disclosed.

According to NASA, the solar storm is travelling towards Earth at a velocity of 1.6 million km/hr and the speed might even increase more.

The satellites in the Earth’s upper atmosphere are also expected to get impacted by the incoming flares. This will directly impact GPS navigation, mobile phone signal and satellite TV. The power grids can also be impacted due to the solar flares.

On the positive side, the solar flares will create an amplified view of Aurora lights in North or South Pole. The people living near the poles will get to experience these lights.
