Space is becoming cheaper, more attractive to investors and increasingly important in our data-rich economy. It's time Australia mapped a path forward.
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.
Australia will be able to guide the Earth observation satellite "NovaSAR" as it passes over our region - giving us a new level of control over the data we need to solve local problems.
Weather forecasting, bushfire management, power and water supply: Australia relies on earth observations to the tune of A$5 billion a year. But we have very little control over the data we get.
