Join our newsletter to get the latest military space news every Tuesday by veteran defense journalist Sandra Erwin.

In a statement May 22, the Space Force said this specialized environment will be crucial for training service personnel, known as guardians, to defend critical satellites and other spacecraft from electronic attacks. Satellites rely on electromagnetic signals for communication, navigation, and data transmission, making them vulnerable to jamming and cyberattacks.

How to create an efficient network between the Internet of Things and satellite constellations

Posted by in categories: internet, satellites

One of the main barriers involves how to connect objects to the internet in places where there is no mobile network infrastructure. The answer seems to lie with low Earth orbit (LEO) satellites, although the solution presents its own challenges.

A new study led by Guillem Boquet and Borja Martínez, two researchers from the Universitat Oberta de Catalunya (UOC) working in the Wireless Networks (WINE) group of the university’s Internet Interdisciplinary Institute (IN3), has examined possible ways to improve the coordination between the billions of connected objects on the surface of the Earth and the satellites in its atmosphere.

The paper is published in the IEEE Internet of Things Journal.

First ‘extreme’ solar storm in 20 years brings spectacular auroras

Posted by in categories: energy, satellites

WASHINGTON: The most powerful solar storm in more than two decades struck Earth on Friday (May 11), triggering spectacular celestial light shows in skies from Tasmania to Britain — and threatening possible disruptions to satellites and power grids as it persists into the weekend.

The first of several coronal mass ejections (CMEs) — expulsions of plasma and magnetic fields from the Sun — came just after 1,600 GMT, according to the National Oceanic and Atmospheric Administration (NOAA)’s Space Weather Prediction Center.

It was later upgraded to an “extreme” geomagnetic storm — the first since the so-called “Halloween Storms” of October 2003 caused blackouts in Sweden and damaged power infrastructure in South Africa. More CMEs are expected to pummel the planet in the coming days.

Redwire announces second VLEO satellite platform

Posted by in categories: business, satellites

WASHINGTON — Redwire Space is doubling down on interest in the emerging market for very low Earth orbit (VLEO) satellites by offering a second spacecraft platform from its European subsidiary.

In a May 9 earnings call, Redwire announced a VLEO satellite platform called Phantom, developed by the company’s European business unit in Belgium. Phantom is being developed for the European Space Agency’s Skimsat mission, on which Redwire is partnered with Thales Alenia Space, and is now being offered for European and international customers.

Phantom joins SabreSat, a VLEO satellite Redwire announced in its previous earnings call in March that is being developed by the company in the United States. The two designs use different technologies.

DARPA Selects Northrop Grumman, Umbra for Phase II of DRIFT Program

Posted by in categories: information science, military, satellites

Northrop Grumman and Umbra have been awarded small contracts by the Defense Advanced Research Projects Agency (DARPA) to continue to the second phase of a program designed to collect data from radar-equipped satellites flying in formation and develop innovative algorithms to process the data for military applications.

Umbra’s contract under the Distributed Radar Image Foundation Technology (DRIFT) program is for $6 million and will last for six months and Northrop Grumman’s is for $2 million and covers one year, a DARPA spokesperson said.
