No GPS, no problem: Researchers are making quantum sensing tools more compact and accurate to replace GPS

Posted by in categories: quantum physics, satellites

Fundamental physics—let alone quantum physics—might sound complicated to many, but it can actually be applied to solve everyday problems.

Imagine navigating to an unfamiliar place. Most people would suggest using GPS, but what if you were stuck in an underground tunnel where radio signals from satellites were not able to penetrate? That’s where quantum sensing tools come in.

USC Viterbi Information Sciences Institute researchers Jonathan Habif and Justin Brown, both from ISI’s new Laboratory for Quantum-Limited Information, are working at making sensing instruments like atomic accelerometers smaller and more accurate so they can be used to navigate when GPS is down.

Europe’s Ariane 6 rocket succeeds in debut flight

Posted by in category: satellites

The European Space Agency’s member countries have endured a space access predicament as they have waited to have a functioning rocket in their toolbox.

But a new rocket, dubbed Ariane 6, just launched on its maiden mission after years of delays and hang-ups in the development process.

If successful, the space agency hopes that the Ariane 6 rocket system may go on to make the space agency more self-reliant and perhaps challenge SpaceX’s dominance in the global market for launching satellites.

Beyond Borders: Applying Modern Conflict Laws as Framework for Outer Space Governance

Posted by in categories: energy, finance, governance, law, military, satellites, surveillance

Moreover, the concept of limitation, which dictates that the means and methods of warfare are not unlimited, can help prevent the escalation of conflicts in space by imposing restrictions on the use of certain weapons or tactics that could cause indiscriminate harm or result in long-term consequences for space exploration and utilization. Given a growing number of distinct weapons systems in orbit – from missile defense systems with kinetic anti-satellite capabilities, electronic warfare counter-space capabilities, and directed energy weapons to GPS jammers, space situational awareness, surveillance, and intelligence gathering capabilities – legal clarity rather than strategic ambiguity are crucial for ensuring the responsible and peaceful use of outer space.

Additionally, the principle of humanity underscores the importance of treating all individuals with dignity and respect, including astronauts, cosmonauts, and civilians who may be affected by conflicts in space. By upholding this principle, outer space law can ensure that human rights are protected and preserved, particularly in the profoundly challenging environment of outer space. Moreover, with civilians on the ground increasingly tethered to space technologies for communication, navigation, banking, leisure, and other essential services, the protection of their rights becomes a fundamental imperative.

The modern laws of armed conflict (LOAC) offer a valuable blueprint for developing a robust legal framework for governing activities in outer space. By integrating complementary principles of LOAC or international humanitarian law with the UN Charter into outer space law, policymakers can promote the peaceful and responsible use of outer space while mitigating the risks associated with potential conflicts in this increasingly contested domain.

Planned SpaceX launch from Florida to carry first satellite built entirely in Turkey

Posted by in category: satellites

July 8 (UPI) — SpaceX is targeting a Monday afternoon launch at Cape Canaveral Space Force Station of a Falcon 9 rocket carrying aloft Turkey’s first home-grown communications satellite.

The launch at 5:21 p.m. EDT can be viewed online.

Turkey has had satellites launched before but this is the first one to be entirely built in the Middle East nation. Turkey is just the 11th country capable of manufacturing its own communications satellites.

Planetary Boundary Layer Revealed: Satellites Illuminate Atmospheric Mysteries

Posted by in categories: climatology, satellites, sustainability

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.

New AI program helps identify elusive space plasmoids

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

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 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 , 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.
