Collaborate Disseminate
Britain has sent two satellites into space that are smaller than a microwave, yet are the smartest ever produced by the UK. On September 28, 2020 at 12:20 pm BST, four Glasgow-built Spire nanosatellites lifted off atop a Russian Soyuz launcher, two of … Continue reading UK’s supercomputer nanosatellites to better predict ship movements
Hardly a week goes by without a headline screaming about some asteroid or another making a close approach to Earth; it’s only by reading the fine print that we remember what an astronomer’s definition of “close” means. Still, 2020 being what it is, it pays to stay on top of …read more
Satellite-threatening debris in high-Earth orbit is not being tracked closely enough, according to the results of a newly published survey. Probes orbiting in geosynchronous orbit – a region of space roughly 36,000 km (22,370 mi) above our planet’s sur… Continue reading Over 75% of space debris detected in new survey is unknown objects
I read about an attack on the TESLA protocol which will be used in Galileo’s navigation message authentication (Full article can be found here: https://doi.org/10.1007/978-3-319-49806-5_1)
Basically, an attacker delays all messages to make… Continue reading Could an attack on time synchronization with a Galileo Satellite be used to spoof navigation messages with TESLA-based authentication?
Taking a page from the Cold War, the US Air Force has announced that it is introducing a new “eSeries” classification for US military air and space hardware. At the virtually-held 2020 Air Force Association Air, Space, and Cyber Conference, Secretary o… Continue reading USAF introduces “eSeries” designation for digitally engineered hardware
Rocket Lab made a successful return to service by launching a customer’s satellite into orbit earlier this week, but that deployment wasn’t the only cause for celebration. The team also managed to insert its own house-built Photon satellite into orbit … Continue reading Rocket Lab launches its two-in-one satellite for deep space missions
Given how many satellites and bits of orbital debris are now orbiting the Earth, it’s becoming increasingly important to keep track of where they all are. A new telescope system allows space agencies and other clients to do so – even in broad daylight…. Continue reading Numerica telescope tracks satellites in broad daylight
Geosynchronous satellites, girdling the Earth from their perches 36,000 km above the equator, are remarkably useful devices. Depending on where they’re parked, they command views of perhaps a third of the globe at a time, making them perfect communications relays. But as [James Pavur] points out in his DEF CON …read more

Can a video game help your company’s staff choose stronger passwords? Why might satellite-based internet communications be bad for security? And what are the alternatives to TikTok?
All this and much much more is discussed in the latest edition of t… Continue reading Smashing Security podcast #191: We are on the bird
It may be named after the most famous volleyball in history, but “Wilson” isn’t just a great conversationalist. [Hayden Brophy] built the free-drifting satellite buoy to see if useful science can be done with off-the-shelf hardware and on a shoestring budget. And from the look of the data so far, …read more
