Geospatial data offers a powerful new way to see the world. But these high-tech images can be misleading or incomplete.
British space firms would get a shot in the arm from building a new GPS-style system if the UK is shut out of the EU’s programme.
New jobs and investment for Australia’s growing space industry are promised with the backing of the new space agency. It’s hoped that all states and territories will benefit from a national approach.
Tech companies such as SpaceX, Facebook, Google and Microsoft are competing to bring internet to areas without access in the developing world. And that’s a problem.
A couple thousand satellites are orbiting Earth right now. Under the right conditions, your naked eye can spot these human-made objects in the night sky.
There are more satellites than ever before, orbiting Earth and collecting data that’s crucial for scientists. Why do some nations choose not to share that data openly?
The wired Earth of the 21st century is at the mercy of the volatile nature of the sun.
China’s Tiangong-1 space station is hurtling around Earth out of control and about to come crashing down. It’s just one of thousands of pieces of space junk left orbiting our planet.
By expanding our understanding of streets and enhancing their design, every street corner could become a space to socialise, to exercise, to play, or to trade.
When Vanguard 1 – the “grapefruit satellite” – was launched in 1958, its only companions were Explorer 1 and Sputnik 2. Soon it may have thousands of descendants swarming around it.
Big data open-access publishing and other advances offer ecologists the ability to forecast events like pest outbreaks over days and seasons rather than decades. But scholars need to seize this opportunity.
Several satellites have been launched in recent years with the objective of measuring data related to climate change. They must be complementary to measurements made on earth.
Space is becoming cheaper, more attractive to investors and increasingly important in our data-rich economy. It’s time Australia mapped a path forward.
Australia is playing a major role in developing legal guidelines that would govern how any war in space is played out. The authors of MILAMOS hope the manual is never actually required.
By taking on the role as leader in space traffic management, Australia can gain international power and exploit commercial opportunities.
A strange patch of extremely strong magnetic field occurred over Jordan in 1000BC. Could we be about to face another one?
New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.
A new approach to monitor changes to the earth’s surface uses maps that consist of physical and human geographic data to explain what’s changed.
We’ve all seen videos of satellites being blasted off into space - but once they’re locked in orbit around the earth, how do we bring them back down?
