Satellite data and neuroimaging reveal how environment can impact brain development

Posted by in category: satellites

A recent study links satellite and brain imaging data to identify how environmental factors can impact mental health, cognition and brain development in young people.

The research, published in the journal Nature Mental Health, is part of a collaboration involving a team of university researchers from around the world led by experts in the tri-institutional Center for Translational Research in Neuroimaging and Data Science (TReNDS Center) based at Georgia State University and New Light Technologies.

The study, titled “Urban-Satellite Estimates in the ABCD Study: Linking Neuroimaging and Mental Health to Satellite Imagery Measurements of Macro Environmental Factors,” represents an advance in understanding how specific environmental conditions may impact the brains of young people.

Laser Precision Unlocks Secrets of Earth’s Gravity and Space Junk

Posted by in category: satellites

Scientists are using laser-based tracking and gravity data to improve how we monitor both satellites and space debris. By blending these methods, they can now predict orbits more precisely and gather insights on Earth’s gravity and water masses.

How are the Earth’s gravitational field and the paths of satellites and space debris connected? Earth’s gravitational field shapes the orbits of satellites and debris, and shifts in these orbits can reveal changes in the gravitational field, which also offers insights into water mass distribution on Earth.

In the COVER project, researchers at TU Graz’s Institute of Geodesy have enhanced gravity field calculations by combining satellite gravity measurements with satellite laser ranging (SLR). This approach not only improves gravity field models but also refines tracking and predictions for objects in orbit. These advancements are now available in the Gravity Recovery Object-Oriented Programming System (GROOPS) software—an open-source tool the Institute provides on GitHub.

World’s first wooden satellite heads to space

Posted by in categories: materials, satellites

The world’s first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.

LignoSat, developed by Kyoto University and homebuilder Sumitomo Forestry, will be flown to the International Space Station on a SpaceX mission, and later released into orbit about 400 kilometers (250 miles) above the Earth.

Named after the Latin word for “wood,” the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore living in space.

Lightning strikes kick off a game of electron pinball in space

Posted by in categories: climatology, particle physics, satellites

When lightning strikes, the electrons come pouring down.

In a new study, researchers at CU Boulder led by an undergraduate student have discovered a new link between weather on Earth and weather in space. The group used satellite data to show that lightning storms on our planet can knock especially high-energy, or “extra-hot,” electrons out of the inner radiation belt—a region of space filled with charged particles that surrounds Earth like an inner tube.

The team’s results could help satellites and even astronauts avoid dangerous radiation in space. This is one kind of downpour you don’t want to get caught in, said lead author Max Feinland.

Australia abandons $5 billion geostationary satellite program to explore ‘multi-orbit’ options

Posted by in categories: government, internet, military, satellites

WASHINGTON — The Australian Department of Defence announced the cancellation of its JP9102 military satellite program, an estimated $5 billion project awarded to Lockheed Martin just 18 months ago, citing shifts in satellite technology and the market’s pivot toward multi-orbit space communications.

The cancellation of Australia’s JP9102 satellite program is yet another sign of the disruptive impact that low Earth orbit space internet services, led by the rapid growth of SpaceX’s Starlink, are having on the traditional satellite communications industry and government procurement models.

JP9102, or Defence Joint Project 9,102, was launched in 2021 with plans to develop between three to five geostationary satellites and ground systems, marking one of Australia’s most ambitious space infrastructure ventures.
