The Importance of the Earth’s Atmosphere in Creating the Large storms that Affect Satellite Communications

Posted by in categories: particle physics, satellites

A study from an international team led by researchers from Nagoya University in Japan and the University of New Hampshire in the United States has revealed the importance of the Earth’s upper atmosphere in determining how large geomagnetic storms develop. Their findings reveal the previously underestimated importance of the Earth’s atmosphere. Understanding the factors that cause geomagnetic storms is important because they can have a direct impact on the Earth’s magnetic field such as causing unwanted currents in the power grid and disrupting radio signals and GPS. This research may help predict the storms that will have the greatest consequences.

Scientists have long known that geomagnetic storms are associated with the activities of the Sun. Hot charged particles make up the Sun’s outer layer, the one visible to us. These particles flow out of the Sun creating the ‘solar wind’, and interact with objects in space, such as the Earth. When the particles reach the magnetic field surrounding our planet, known as the magnetosphere, they interact with it. The interactions between the charged particles and magnetic fields lead to space weather, the conditions in space that can affect the Earth and technological systems such as satellites.

An important part of the magnetosphere is the magnetotail. The magnetotail is the part of the magnetosphere that extends away from the Sun, in the direction of the solar wind flow. Inside the magnetotail is the plasma sheet region, which is full of charged particles (plasma). The plasma sheet is important because it is the source region for the particles that get into the inner magnetosphere, creating the current that causes geomagnetic storms.

EXCLUSIVE: The ‘Impossible’ Quantum Drive That Defies Known Laws of Physics was Just Launched into Space

Posted by in categories: quantum physics, satellites

A controversial new electric propulsion system, which physicists say defies Newton’s Laws of Motion, was launched into space this weekend aboard a Space X rocket.

Developed by electronics prototyping company IVO Ltd, the Quantum Drive took flight Saturday morning, November 11th, aboard SpaceX’s Transporter 9 mission. This flight included over 80 separate payloads destined for Low Earth Orbit (LEO).

“Launch and deployment were successful!” IVO’s owner and founder, Richard Mansell, told The Debrief in a Sunday email. “We’re getting the satellite’s ‘heartbeat.’ Next step is to establish communication with the satellite.”

SpaceX Artist-in-Residence on painting spacecraft and Starlink satellites: ‘The machine is my patron’ (exclusive)

Posted by in categories: internet, robotics/AI, satellites

Provocative Silicon Valley artist Agnieszka Pilat has strong beliefs regarding the intermingling of art, religion and technology, something that keeps her fertile muse alert amid multiple presentations, exhibitions and appearances at global events such as the recent TED AI 2023 conference in San Francisco.

The Polish-born Pilat’s current SpaceX Artist-in-Residence program at the aerospace firm’s Hawthorne, California facility will likely run through 2024 and comes right before a December exhibition at the National Gallery of Victoria’s Triennial in Australia. There, for three months, her black-and-yellow Boston Dynamics robodogs will be creating autonomous artwork via a series of pre-programmed instructions.

SpaceX selling ‘Starshield’ will be a gamechanger

Posted by in categories: alien life, internet, military, nuclear weapons, satellites

Space Force and SpaceX announced that they’ve reached a deal for a brand-new military capability: Starshield. Is it a new laser defense shield against nuclear missiles? An Ultron for our time to destroy alien armadas? Or Starlink, but with new branding and (probably) a new fleet of satellites?

Yup, the last one. But with how clutch Starlink is in Ukraine, a military-controlled version of the network could change operations there. And it would dramatically improve U.S. and allied military communications in future conflicts. Now, the American military will lead military space-based communications with the start of Starshield. But expect allies to clamor aboard and other nations to try developing rival platforms.

Space Force has one of the most descriptive, succinct names in the modern military, but it appears to be even worse at naming its programs than the other branches. Still, its Proliferated Low Earth Orbit Program, or “PLEOP,” for acronym addicts who want to hear the sound of a dump every time they discuss the program, is promising.
