X-Cubesat and Spacecube successfully launched from the ISS

19 May 2017

X-Cubesat, the satellite designed by students from the French École Polytechnique, was placed in orbit from the International Space Station on 17 May at 3.45am (local). The cubesat is operational, and the very first telemetry was received by an amateur radio station in the Netherlands and sent to the École Polytechnique.

The best way to transmit satellite data? In trucks. Really

17 May 2017

AN UNMARKED WHITE semi-truck rests on orange steel plates—Rent Me, they proclaim—protecting the soft ground outside a glass-fronted office building in Westminster, Colorado. Inside the cargo container, locked up in refrigerated drives, is a photo album of Earth. Over 17 years, a company called DigitalGlobe has painstakingly collected those images from its high-resolution satellite network. And on this May morning, it's set to ship those precious 100 petabytes to Amazon and its cloud-based Web Services.

Satellites play vital role in spotting, monitoring fires

11 May 2017

Fires, whether naturally occurring or man-made, have substantial impacts on both the landscape and air quality. Fortunately, satellites can detect and monitor fires large and small, and provide data on a range of factors, including location, duration, size, temperature and intensity.

Where old satellites go to die

02 April 2017

After almost 20 years of service - a remarkable feat, given its expected lifetime of five years - a series of manoeuvres will be carried out to take the Meteosat-7 satellite out of its current geostationary orbit, 36,000km above the Earth, to its new and final resting place.

CanX-7 nanosatellite validates aircraft tracking, prepares deorbit demo

30 March 2017

The CanX-7 nanosatellite built by Space Flight Laboratory (SFL) at the University of Toronto Institute for Aerospace Studies (UTIAS) has validated real-time detection and tracking of aircraft by satellite in low-Earth orbit. The next mission phase will begin in early May with deployment of drag sails developed by SFL to accelerate the deorbiting of small satellites as a practical solution to the space debris problem.

Timing a space laser with a NASA-style stopwatch

27 March 2017

To time how long it takes a pulse of laser light to travel from space to Earth and back, you need a really good stopwatch — one that can measure within a fraction of a billionth of a second.
