Advanced techniques allowed our research team to build an open database of billions of individual trees and challenge some common perceptions about vegetation in arid and semi-arid zones.
We used satellite images to study the life cycles of mangrove forests in the Northern Territory, Queensland, and New South Wales — and found a surprising degree of variation.

Flaring, or burning, waste gas from energy production has sharply increased over the past decade. It wastes usable fuel, pollutes the air, and helps drive climate change.
A scientist whose Kangaroo Island home was threatened by the summer’s bushfires says there is a ‘knowledge gap’ between satellite data and useful maps that can protect communities.
NASA’s Worldview software gives you a satellite view of Earth right now, and can help track the spread of fires.

China has embraced the concept of Digital Earth – the use of data from satellites to create a visual map of what’s happening at every point on the planet – and is now a key player in making it happen.
The electromagnetic spectrum we can access with current technologies is completely occupied. This means experts have to think of creative ways to meet our rocketing demands for data.

Free space optical communication will allow the same connectivity in space we already have on Earth. And this will provide benefits across a number of sectors.

Hundreds of millions more people will now be at risk from rising seas in the coming decades - with Asia and island nations most vulnerable. How we react to the climate crisis is now even more crucial.
