Space Force opens bidding for classified communications satellites

Posted by in categories: military, satellites

Join our newsletter to get the latest military space news every Tuesday by veteran defense journalist Sandra Erwin.

This estimated $8 billion procurement, known as Evolved Strategic Satcom (ESS), will supplement and eventually replace the existing Advanced Extremely High Frequency (AEHF) satellite constellation. The new system will provide critical jam-resistant communication channels for the National Command Authorities and deployed forces worldwide, even in the North Polar region – a capability lacking in the current system.

Space Age Security: How Satellites Could Extend Quantum Encryption Globally

Posted by in categories: computing, encryption, engineering, internet, quantum physics, satellites, security

How can we guarantee that data sent over the internet is only accessible to its intended recipient? Currently, our data is secured using encryption methods based on the premise that factoring large numbers is a complex task. However, as quantum computing advances, these encryption techniques may become vulnerable and potentially ineffective in the future.

Encryption by means of physical laws

Tobias Vogl, a professor of Quantum Communication Systems Engineering, is working on an encryption process that relies on principles of physics. “Security will be based on the information being encoded into individual light particles and then transmitted. The laws of physics do not permit this information to be extracted or copied. When the information is intercepted, the light particles change their characteristics. Because we can measure these state changes, any attempt to intercept the transmitted data will be recognized immediately, regardless of future advances in technology,” says Tobias Vogl.

World’s most advanced solar sail rockets into space

Posted by in category: satellites

The world’s most advanced solar sail spacecraft began its odyssey today at 23:32 GMT as it lifted off atop a Rocket Lab Electron launcher from Launch Complex 1 in Mahia, New Zealand. It was one of two payloads on the Beginning Of The Swarm mission.

Though it’s only the size of a microwave oven, NASA’s Advanced Composite Solar Sail System (ACS3) can unfurl a microscopically thin plastic sail in about 25 minutes to cover an area of 860 ft² (80 m²) with a boom unfolding from the size of a hand to 23-ft (7-m) long. It’s not the first solar sail to be sent into space, but its boom made of lightweight polymer composites and specially configured to stow flat is a major step in making such sails lighter and more stable.

The big idea: are we about to discover a new force of nature?

Posted by in categories: military, nuclear energy, particle physics, satellites

I found this on NewsBreak: The big idea: are we about to discover a new force of nature?


Intriguingly, both disciplines are grappling with unexplained results that could be pointing to the existence of a new force of nature. If such a new force were to be confirmed, the implications for our understanding of the universe, its history and makeup would be profound.

There are four forces that we already know about. Gravity governs the grandest scales, marshalling the planets in their orbits and shaping the evolution of the universe as a whole. Electromagnetic force gives rise to a vast range of phenomena, from the magnetic field of the Earth to radio waves, visible light and X-rays, while also holding atoms, molecules and, by extension, the physical world together. Deep within the atomic nucleus, two further forces emerge: the vice-like “strong force”, which binds atomic nuclei, and the “weak force”, which among other things causes radioactive decay and enables the nuclear reactions that power the sun and the stars.

Vast to use Starlink for space station broadband communications

Posted by in categories: internet, satellites

COLORADO SPRINGS — Commercial space station developer Vast will use SpaceX’s Starlink constellation to provide broadband connectivity for its Haven-1 station launching next year.

Vast announced April 9 that it will install laser intersatellite link terminals on its Haven-1 station to enable communications with Starlink satellites. The agreement between Vast and SpaceX extends to future space stations Vast plans to develop.

Max Haot, chief executive of Vast, said in an interview during the 39th Space Symposium that his company will use terminals supplied by SpaceX. Gwynne Shotwell, president of SpaceX, announced at the Satellite 2024 conference March 19 that SpaceX would sell laser terminals it developed for Starlink to other customers, a product offering she dubbed “Plug ’n’ Plaser.”

Invention Can ‘Shield’ Quantum Computers From Magnetic Interference

Posted by in categories: computing, quantum physics, satellites

PRESS RELEASE — Magnetic Shields Limited (MSL) has invented a lightweight and small-scale magnetic shielding system for cryogenic conditions.

The innovation developed by UK-based MSL in collaboration with the University of Nottingham and quantum computer developer SEEQC will revolutionise quantum computing performance and efficiency. The coil shield also has implications for satellites, where payload weight determines launch costs.

The shield is the first to integrate thin metal coils into magnetic shielding to actively cancel out magnetic field interference in temperatures near absolute zero. It eliminates the need for bulky metal housings.
