Clouds are powerful agents of global change. They affect the overall temperature or energy balance of the Earth and play a large role in controlling the planet's long-term climate. We need accurate data on clouds to understand their impact over time. NASA and others have a number of satellites orbiting the Earth and collecting data about clouds and Earth’s energy. While these satellites give us a big picture of what’s going on, they sometimes have trouble with the details. We need your…
Tracking seals from outer space
Shanelle Dyer is an MSc Geography student at the University of Canterbury, using remote sensing and GIS for conservation. Her thesis focuses on counting Weddell seals in the Ross Sea Marine Protected Area (MPA) in Antarctica, in an effort to see how well MPAs protect our vulnerable marine life.
Dramatic satellite images have laid bare New Zealand's biodiversity crisis, revealing how thousands of hectares of native habitat have vanished in just a few years. Forest & Bird says the Manaaki Whenu-Landcare Research data, showing decreases in 12 of 13 types of native habitat over the last decade, signals the need for better policy to protect what we've got left. The call comes as the Government is asking for feedback on a set of proposed bottom-lines for regional councils to identify…
MethaneSAT is a satellite designed to locate and measure methane from human sources worldwide, giving both companies and governments new ability to track, quantify, and reduce those emissions — and supplying the public with data to see that the job is being done.
Times to Spot the Space Station
It’s easy to see the International Space Station passing overhead: you just need to know when and where to look. Oh, and a clear sky. The International Space Station (ISS) regularly passes across New Zealand, a little more than 400 km above our heads – rather less than the distance between Auckland and Wellington. Most of these transits occur either in daytime, making the ISS difficult (though not impossible) to see against the sky, or in the depths of night, when it is dark because it is in…
International Astronomical Union | IAU
The International Astronomical Union (IAU) is concerned about these satellite constellations. The organisation, in general, embraces the principle of a dark and radio-quiet sky as not only essential to advancing our understanding of the Universe of which we are a part, but also as a resource for all humanity and for the protection of nocturnal wildlife. We do not yet understand the impact of thousands of these visible satellites scattered across the night sky and despite their good…
Rosetta Mission scientists used early images of Comet 67P to create a virtual model of the comet. This virtual model was used to pinpoint the best place to land Philae, the lander. Avionics engineer Warwick Holmes describes the process of landing Philae and the unexpected touchdown results.
Satellites measure sea ice thickness
Satellites help scientists measure the thickness of land and sea ice in Antarctica. To validate these measurements, Dr Wolfgang Rack from Canterbury University travels to Antarctica each year to physically measure the thickness of land and sea ice.
