A hack on satellites could cripple much of our digital infrastructure.

Though SpaceX has yet to announce this mission, the Federal Aviation Administration and Space Coast Office of Tourism now report the Türksat 6A satellite will launch Monday afternoon — though the target date has bounced around the past couple days.

Mission: A SpaceX Falcon 9 rocket will deploy Turkey’s first domestically manufactured geostationary communications satellite, the Space Coast Office of Tourism reports.

Value. Space uses satellites to assess risks to infrastructure.

New research has unraveled the complex dynamics of the planetary boundary layer, enhancing satellite detection of atmospheric pollutants and aiding environmental management and climate modeling efforts.

A new study has provided groundbreaking insights into Earth’s planetary boundary layer (PBL), a crucial area that affects air quality and climate. By analyzing satellite data, researchers have explored how the temperature gradient from the surface to the atmosphere impacts the identification of atmospheric pollutants, offering a deeper understanding of atmospheric thermal contrasts (TC).

The endeavor to keep tabs on and curb air pollution has been stymied by the enigmatic nature of the planetary boundary layer (PBL). This atmospheric strip, in constant caresses with the Earth’s surface, is a hotbed for pollutants. Yet, its mercurial dance through time and across geographies presents a formidable scientific puzzle. Given these hurdles, an in-depth dissection of the thermal contrast (TC) that delineates this layer is imperative.

In an ongoing game of cosmic hide and seek, scientists have a new tool that may give them an edge. Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have developed a computer program incorporating machine learning that could help identify blobs of plasma in outer space known as plasmoids. In a novel twist, the program has been trained using simulated data.

The program will sift through reams of data gathered by spacecraft in the magnetosphere, the region of outer space strongly affected by Earth’s magnetic field, and flag telltale signs of the elusive blobs. Using this technique, scientists hope to learn more about the processes governing magnetic reconnection, a process that occurs in the magnetosphere and throughout the universe that can damage communications satellites and the electrical grid.

Scientists believe that machine learning could improve plasmoid-finding capability, aid the basic understanding of magnetic reconnection and allow researchers to better prepare for the aftermath of reconnection-caused disturbances.

Liftoff is scheduled for 2:57 a.m. ET on Wednesday (July 3).

WASHINGTON — Turion Space, an Irvine, California-based startup, has secured a $1.9 million contract from SpaceWERX, the U.S. Space Force’s technology arm, to develop an autonomous spacecraft docking and maneuvering system. The contract aims to advance technologies for engaging uncooperative space objects and facilitating the deorbit of inactive satellites.

Ryan Westerdahl, Turion’s co-founder and CEO, said in an interview that the company is focusing on in-space mobility and non-Earth imaging. Turion launched its first satellite, Droid.001, a 32-kilogram spacecraft designed for space situational awareness, in June 2023. Data from this satellite is being integrated into the Space Force’s Unified Data Library.

Westerdahl revealed plans for a demonstration as early as 2026, featuring a Droid mothership hosting “micro-Droid” satellites equipped with the capturing device being developed under the SpaceWERX contract. The micro-Droid, partly funded by NASA, will use grapplers to capture debris objects.

Ever since aurora chasers discovered Steve, a mysterious ribbon of purple light in the night sky, scientists have wondered whether it might have a secret twin. Now, thanks to a photographer’s keen eye, and data from ESA’s Swarm satellites, we may have found it.

Steve was a sensation when scientists stumbled across it a few years ago, thanks to the eagle eyes and excellent photography of the Alberta Aurora Chasers Facebook group.

But its mauve hue and fleeting appearance meant it couldn’t be a feature of the aurora borealis, commonly known as the northern lights, which comes in shades of green, blue and red and can last for hours. So, what could it be?
