0:15 Mini-factories in space – Space Forge says its technology could revolutionize manufacturing. The satellites contain miniature manufacturing systems. They take advantage of the conditions in low-Earth orbit such as microgravity, extreme temperatures and a contaminant-free environment to forge materials that would be impossible to manufacture here on Earth.
1:53 Biodiversity credits explained – Nature is under unprecedented threat. Around 2 million plant and animal species could go extinct in the next few decades as climate change and habitat loss push ecosystems towards irreversible tipping points.
