5 trillion bytes a day: SpaceX engineers flash some facts about Starlink satellites

Posted by in categories: internet, satellites

SpaceX’s Starlink satellite constellation is still deep into testing mode, but it’s already generating 5 trillion bytes of data on a daily basis and getting software updates on a weekly basis.

Those are a couple of the nuggets coming from a weekend Reddit “Ask Me Anything” session featuring SpaceX’s software team.

Air Force Pilots Are About to Do Battle With Autonomous Drones

Posted by in categories: drones, military, robotics/AI, satellites

Changing Course

The Air Force announced an AI initiative called “Skyborg” last March with the goal of flying fighter jets without anyone at the controls. Now, Shanahan says that the Air Force may be more interested in swarm drones and other uses for AI than necessarily taking the pilot out of a fighter plane’s cockpit.

“Maybe I shouldn’t be thinking about a 65ft-wingspan, maybe it is a small autonomous swarming capability,” Shanahan told BBC News. “The last thing I would claim is that carriers and fighters and satellites are going away in the next couple of years.”

SpaceX to launch 60 Starlink satellites for megaconstellation tonight. Here’s how to watch

Posted by in categories: internet, satellites

SpaceX will launch its next batch of Starlink internet satellites into orbit tonight (June 3) after two weeks of weather delays and the company’s historic first astronaut flight.

A Falcon 9 rocket, which SpaceX has already flown four past missions, will launch 60 new Starlink satellites into orbit from the company’s pad at Launch Complex 40 at Cape Canaveral Air Force Base in Florida. Liftoff is set for 9:25 p.m. EDT (0125 June 4 GMT).

A new plasma engine will allow less expensive, more efficient, and longer space missions

Posted by in category: satellites

Researchers at Universidad Carlos III de Madrid (UC3M) have patented a new spatial plasma-fueled engine capable of satellite and spacecraft propulsion, with magnetic field geometry and configuration that would minimize losses on walls and their erosion, thereby resolving issues of efficiency, durability, and operating restrictions of engines that are currently in orbit.

A new scheme for satellite-based quantum-secure time transfer

Posted by in categories: encryption, quantum physics, satellites, security

Researchers at the University of Science and Technology of China have recently introduced a new satellite-based quantum-secure time transfer (QSTT) protocol that could enable more secure communications between different satellites or other technology in space. Their protocol, presented in a paper published in Nature Physics, is based on two-way quantum key distribution in free space, a technique to encrypt communications between different devices.

“Our main idea was to realize quantum-secure time transfer in order to resolve the in practical time–frequency transfer,” Feihu Xu, one of the researchers who carried out the study, told

Quantum key distribution (QKD) is a technique to achieve secure communication that utilize based on the laws of quantum mechanics. Quantum protocols can generate secret security keys based on , enabling more secure data transfer between different devices by spotting attackers who are trying to intercept communications.

First Object Teleported from Earth to Orbit

Posted by in categories: encryption, quantum physics, satellites

Essentially a quantum radar teleportation device could entangle objects anywhere in the universe.

Last year, a Long March 2D rocket took off from the Jiuquan Satellite Launch Centre in the Gobi Desert carrying a satellite called Micius, named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day.

Micius is a highly sensitive photon receiver that can detect the quantum states of single photons fired from the ground. That’s important because it should allow scientists to test the technological building blocks for various quantum feats such as entanglement, cryptography, and teleportation.

Solving the space junk problem

Posted by in categories: life extension, satellites

Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to capture debris or deorbit old satellites: it’s an international agreement to charge operators “orbital-use fees” for every satellite put into orbit.
