Comparing the landscape of Mars to Earth

Can we compare the surface of Mars to that of Earth? Re-visiting old tech, and wearable devices that can generate electricity from the skin.

‘With every new view from the surface of Mars comes a reminder of just how fortunate we are to live on Earth.’ Acclaimed science writer and filmmaker Dr Chris Riley uses images from the landing sites on Mars to compare relative locations on Earth. Hear how you might be able to help.

Old Tech
Our Digital Planet social media community is a-buzz with stories of old technology, and the role you have had in technological history. Several listeners share their experiences with expert opinion from the curator of Technology and Engineering at the Science Museum Dr Rachel Boon.

Wearable Thermoelectric Batteries
Thermoelectric technologies are able to generate electricity by manipulating heat differences, but they are usually bulky and fragile. Dr Jianliang Xiao, and his team based in Colorado, discuss advancements in material composition that have led to the creation of a self-healing and recyclable battery with the potential to power wearable devices.
