SAN FRANCISCO – Iceye and Kongsberg Satellite Services (KSAT) announced plans Sept. 25 to extend their joint campaign to speed up access to synthetic aperture radar (SAR) data for government and commercial customers. “The newly signed contract covers further data purchases and extended operations of Iceye’s near real-time SAR processor within the KSAT ground network,

WAILEA, Hawaii — Despite the ongoing debate about the orbital debris risks posed by proposed satellite megaconstellations, one expert believes that an even greater risk comes from clusters of objects already in orbit. In a concluding presentation at the Advanced Maui Optical and Space Surveillance Technologies, or AMOS, conference here Sept. 20, Darren McKnight of

As it looks increasingly unlikely we’re going to meet our climate mitigation targets, scientists have been investigating more and more extreme solutions, such as geoengineering. Examples include spraying huge amounts of sunlight-reflecting particles into the atmosphere, or dumping trillions of tons of fake snow onto glaciers to stabilise them. These ideas are untested, incredibly risky,

Sounds like the Defense Advanced Research Projects Agency (DARPA) was just kicked out of mom’s basement. In an inexplicable tweet, DARPA asked for help finding “commercially managed underground urban tunnels and facilities able to host research and experimentation.” And nobody knows why. The ideal space would be a human-made underground environment spanning several city blocks w/

WAILEA, Hawaii — With satellite operators doing a poor job complying with guidelines to deorbit their satellites, incentives or even regulation may be inevitable to address concerns about orbital debris and satellite collisions. During a Sept. 19 presentation at the Advanced Maui Optical and Space Surveillance Technologies, or AMOS, conference here, Francesca Letizia, an engineer

It’s springtime Down Under, and along with overexuberant local football fans, that means another annual menace on Australian streets: angry birds. September is peak magpie breeding season. And like much of Australia’s native wildlife — think deadly snakes, spiders and jellyfish — the country’s magpies are meaner than those found elsewhere. Male birds defending their

A team of researchers has just demonstrated quantum enhancement in an actual X-ray machine, achieving the desirable goal of eliminating background noise for precision detection. The relationships between photon pairs on quantum scales can be exploited to create sharper, higher-resolution images than classical optics. This emerging field is called quantum imaging, and it has some

According to new research, the dead may not always rest in peace… quite literally. For more than a year after death, corpses move around “significantly”, and this finding could be important for forensic investigations. Researchers at an Australia-based decomposition research facility – colloquially known as a “body farm”, a term some scientists find disrespectful –

PARIS — The European Union’s equivalent of a foreign ministry is starting a new effort to promote the need for sustainable space operations, but that effort will not initially include any new regulation of European satellite operators. Carine Claeys, special envoy for space and head of the Space Task Force for the European External Action
