Fifty years since the first moonwalk, space technology has made a huge difference to life on earth – just think about all those weather and telecommunications satellites orbiting way above us.

In an interview with UN News’s Kina Vujanic-Beck to celebrate World Space Week 2019, UNOSAT’s Dr. Einar Bjorgo, explains how technology out there in orbit, can be applied for development and humanitarian ends.
