World Wise Web

Aerospace engineer Dr Anita Sengupta led the team that developed the supersonic parachute which helped land Nasa’s Curiosity rover on Mars in 2012. It’s still on the Red Planet today, and its main goal is to assess whether there is, or ever was, life on Mars. She tells 17-year-old astrophysics enthusiast Avantika, from India, how her love of space began when she watched a science-fiction show on TV.

Eighteen year old Michael, from Dubai, who wants to become an engineer, talks to Keller Rinaudo, whose company Zipline has built what they say is the world’s fastest delivery drone. Travelling at more than 100 km per hour, these battery-powered aircraft look like small planes. Doctors in remote areas of Rwanda and Ghana send requests for medical supplies via text and Whatsapp, which the drone then delivers. We hear how they work and how the doctors first reacted to them.

Eighteen-old-entrepreneur Leander, from Greece, discovers how sci-fi became reality, through the work of leading orthopaedic surgeon Professor Munjed Al Muderis. He has developed a new generation of implants for amputees which replaces the traditional socket based technology with a robotic prosthetic limb. We also hear about Professor Al Muderis’s life, and the journey he made as a refugee from Iraq to Australia.
