Population growth is creating a huge demand for infrastructure, even as environmental risks grow. To detect problems early, satellites can provide rich data to help assess infrastructure "health".

The first 60 satellites from Elon Musk's planned low orbit internet network have lit up the skies. But with more planned, astronomers say the satellites could ruin their work.
India, China, the United States and Russia can now precisely target objects in space. But we currently lack appropriate rules and regulations to deal with space weapons.
On 27 March, India announced it had successfully conducted an anti-satellite missile test, Mission Shakti. India is now the fourth country in the world displaying this capability.
Since 2008, Landsat data has been free for the world to use, spurring new applications and scientific research. But that door could soon slam shut.
Satellites hundreds of miles overheard are helping scientists to predict drought, track floods and see how climate change is changing access to water resources.
The flood zone around Townsville extends for hundreds of kilometres, making monitoring difficult even from the air. But scientists are testing a new satellite method that can peer through the clouds.
New satellite-based research shows there is at least as much value in knowing how much water is left for plants to use as there is in knowing how much rain may be on the way.
If the Australian space industry is to grow and create thousands of jobs then we need new policy around satellites to meet the challenges involved.
The Open Air project features satellite data interpreted and coloured to produce beautiful, surreal images of Australian landforms.
When a dam comes down this fall, a team of scientists will be there to track the environmental changes.
Could Canadian technology play a part in the newly announced U.S. Space Force? A team at McMaster University has developed an instrument that could keep Space Force troops safe from radiation.
High altitude images of Earth's surface can illustrate events occurring on a grand scale to the public.
Let's launch Australian satellites on Australian rockets from Australian sites, and operate them from Australian facilities.
We've launched rockets from Woomera in South Australia, but in reality Australia could support multiple launch sites. And the closer to the equator, typically the better.
Illegal dumping is costing governments millions – but satellite technology could help put a stop to it.
Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
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.
