This Earth Science Week on Fuzzy Logic we chat with experts from Geoscience Australia about harnessing the power of space technology to tackle our biggest challenges.

For fifty years, the partnership between Geoscience Australia and the United States Geological Survey has revolutionized our understanding of the Earth from space.

Through the Landsat program, we’ve gained invaluable insights into our environment, from monitoring deforestation and urban growth to managing water resources and agricultural lands.

Tune in to hear David Hudson, Medhavy Thankappan and Eloise Birchall from Geoscience Australia chat to Broderick about Landsat and Landsat Next.

A triumph of our civilisation are the things that go on under the covers without us even noticing. When you pour stuff down the sink or flush it down the toilet, where does it go? Luckily, we don't need to think about it...until somebody does the wrong thing.

That's when we should hail the invisible, unsung heroes of this story. That's right, these are the people that go down into the bowels - literally - of a city's plumbing to do what must be done.

We can do our bit, it's not difficult... think before you flush.

Here, Rod interviews Davina McCormick, General Manger Customer Engagement at ICON water.

If you're in Floriade this weekend (21-22 Sep), be sure to see their display. Gritty, but highly recommended.

A guest podcast from Valerie Albrecht.

This podcast offers reflective space to consider the relationship between sustainability and spirituality. Is there one? Could practising sustainability nurture spirituality? Could practising some form of spirituality help us to live more sustainably? Could spirituality help us to give right place to all that is losing sustainability? Contributors from a cross section of professions and viewpoints share their knowledge, perspectives and wisdoms: a Heritage Officer Anthropologist Activist; a gardener; a writer and artist; a priest; a physics teacher, and some Australian Aboriginal healers I have had the privilege of learning with. Share your sustainability and spirituality reflections at www.theoceansofenergy.com Thank you contributors. Music: Tony O’Connor Uluru.
