Spacemen are to visit Edinburgh to talk about how views of the Earth from space have changed in the past 50 years.

Veteran cosmonaut Viktor Petrovich Savinykh will lead an expert panel that will discuss photographs taken from half a century of space travel.

During the event, the Russian will join fellow cosmonaut Sergei Vasilyevich Avdeev and NASA astronaut Dr Jay Apt to talk about their own experiences.

The experts will also talk about the effects of natural and human activity on the Earth’s environment and how space research has tried to address these issues.
