France is considering using lasers to protect its military space assets

France has announced it will expand its military space assets and defend them using systems that may include anti-satellite lasers. In a speech before the Commandement de Défense Aérienne et des Opérations Aériennes (Command of air defense and air operations, CDAOA) at Air Base 942 Lyon Mont-Verdun, the Minister of the Armed Forces, Florence Parly said that the government will spend an additional €700 million (US$780 million) by 2025 to produce new surveillance satellites with self-defense capabilities.

Inside the Mysterious Global Navigation Outage You Probably Didn’t Notice

Posted on by

The entire world has come to depend on satellite navigation systems in the forty or so years since the first Global Positioning System satellites took to orbit. Modern economies have been built on the presumption that people and assets can be located to within a meter or better anywhere on, …read more

Artist concept of the TESS spacecraft which recently observed a supernova and the elemental content of ...

NASA’s Transiting Exoplanet Survey Satellite (TESS) was built to search for new planets, but astronomers at Ohio State discovered that it could also observe supernovas created by exploding white dwarf stars. This development means we might soon have a better idea about why they explode, and what they leave behind in the process.

Researchers from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of Bath are developing a technique that uses satellite radar imaging to monitor the safety of bridges and other large-scale infrastructure. Us… Continue reading Satellite-based radar could spot faulty bridges from space→

It’s NICER in Orbit

Posted on by

Given the sheer volume of science going on as the International Space Station circles above our heads every 90 minutes or so, it would be hard for any one experiment to stand out. ISS expeditions conduct experiments on everything from space medicine to astrophysics and beyond, and the instruments needed …read more

Earth's eighth persistent lava lake found on remote sub-Antarctic island

Posted on by

In this image captured by the Copernicus Sentinel-2 mission, a distinct hotspot can be seen in ...

Many of us will know what bubbling lakes of lava within volcanoes look like. After all, we’ve seen them our entire lives in movies, TV shows and cartoons. But that doesn’t mean they’re common. In fact, only seven lava lakes have been found so far, until now. After 30 years of suspecting the existence and location of the eighth, a team of scientists has finally confirmed it – within the crater of a remote, Subantarctic island volcano.

In the fall of 1957, it seemed as though the United States’ space program would never get off the ground. The USSR had launched Sputnik in October, and this cemented their place in history as the first nation in space. If that weren’t bad enough, they put Sputnik 2 into …read more

Recently declassified US spy satellite images reveal Himalayan glaciers have been melting at an accelerating rate

It’s not entirely news that the Earth’s ice budget is under threat from a warming climate, but a new study has looked into just how fast that’s happening. Using recently declassified spy satellite photos, researchers found that compared to the last quarter of the 20th century, Himalayan glaciers have been melting twice as fast this century. In a rare piece of good news, a separate study has shown that a Greenland glacier has gained ice for the third year in a row.
