South Korea launches second military spy satellite

Posted by in categories: existential risks, military, satellites

The Koreas each launched their first spy satellites last year — North Korea in November and South Korea in December — amid heightened animosities. They said their satellites would boost their abilities to monitor each other and enhance their own missile attack capabilities.

South Korea’s second spy satellite was launched from the Kennedy Space Center in Florida on Sunday evening local time, which was Monday morning in Seoul.

South Korea’s Defense Ministry said it confirmed the satellite entered orbit and communicated with an overseas ground station after separation from a rocket.

Next-Gen Refueling Spacecraft to Revitalize Satellites in Geostationary Orbit

Posted by in categories: energy, health, satellites

The Southwest Research Institute (SwRI) is developing a spacecraft named Astroscale Prototype Servicer for Refueling (APS-R) as part of a $25.5 million project with the U.S. Space Force.

Southwest Research Institute (SwRI) will build, integrate, and test a small demonstration spacecraft as part of a $25.5 million Space Mobility and Logistics (SML) prototyping project funded by the U.S. Space Force and led by prime contractor Astroscale U.S. The spacecraft, called the Astroscale Prototype Servicer for Refueling (APS-R), will refuel other compatible vehicles while in geostationary orbit.

“Running low on fuel is a common issue for spacecraft in Earth orbit,” said SwRI Staff Engineer Steve Thompson, the SwRI project systems engineer. “When they have expended all of their fuel, their mission ends — even though the vehicle may be in otherwise excellent health. A refueling vehicle can extend those missions, and we can get additional lifetime out of spacecraft that are already in orbit.”

Rocket Explodes Seconds After Launch

Posted by in categories: drones, energy, satellites

A Japanese rocket by startup Space One has exploded in spectacular fashion following a launch attempt earlier today.

It’s yet another major setback for the company, which was hoping to become Japan’s first commercial entity to launch a satellite into orbit, the New York Times reports.

Drone footage shows the dramatic scene. At first, everything appears to go fine as the solid-fuel rocket dubbed Kairos lights its engines. But it doesn’t take long for the rocket to seemingly veer off path, erupting into a massive cloud of smoke just seconds later, causing major pieces of debris to rain down on the launch pad and engulf parts of the facility and a neighboring forest in flames.

NOAA Satellites Detect Severe Solar Storm

Posted by in category: satellites

From March 23–24, 2024, NOAA’s GOES satellites, and others operated by international partners, observed numerous flares erupt from the sun, including a powerful X-class solar flare. Additionally, a surge of extremely hot plasma, known as a coronal mass ejection (CME), raced toward Earth resulting in geomagnetic storms and auroras.

This CME reached our planet at 10:37 a.m. EDT (1437 GMT) on Sunday, March 24, triggering a severe G4-class geomagnetic storm, marking the most potent solar storm since 2017. However, according to a Geomagnetic Storm Watch from NOAA’s Space Weather Prediction Center, there was no reason for the public to be alarmed.

Solar Cycle 25 is Exceeding Predictions and Showing Why We Need the GDC Mission

Posted by in category: satellites

This is the solar maximum I was talking about. Happening in 2025 on earth.


December 2019 marked the beginning of Solar Cycle 25. The Sun’s activity has quickly ramped up and even though we haven’t reached peak levels in this cycle, the Sun’s activity is already exceeding predictions. Solar events will continue to increase as we near solar maximum in 2025, and our lives and technology on Earth, as well as satellites and astronauts in space, will be impacted.

NASA’s Heliophysics Division is developing a mission that will provide crucial advances in our understanding of the ionosphere-thermosphere (I-T) system – the Geospace Dynamics Constellation (GDC). This mission will provide the first coordinated global-scale observations of the I-T region, where the effects of solar activity are often seen. The I-T region is a part of Earth’s upper atmosphere that extends up to about 400 miles altitude and includes low-Earth-orbit, where the International Space Station and many commercial and governmental satellites reside. The I-T system is a region that affects our technological society in many ways, from creating interference in radio signals to generating large electric currents in power distribution systems. The GDC mission’s study of the global, coupled system will enable dramatic improvements in our space weather models, which will lead to the mitigation of negative effects on space-based, air-based, and ground-based assets.

New cataclysmic variable discovered by astronomers

Posted by in categories: physics, satellites

By analyzing the data from ESA’s XMM-Newton and Gaia satellites, astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany and elsewhere have detected a new magnetic cataclysmic variable system, most likely of the polar type. The finding was reported in a research paper published March 21 on the pre-print server arXiv.

Future quantum computers will be no match for ‘space encryption’ that uses light to beam data around — with the 1st satellite launching in 2025

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

Quantum computers will break encryption one day. But converting data into light particles and beaming them around using thousands of satellites might be one way around this problem.
