US space agency Nasa has launched a competition to find “space apps” to aid space exploration and education.
The two-day event will bring programmers together on seven continents to see how creative they can be with Nasa’s store of space data.
Problems Nasa wants solved include improving data sharing after disasters and spotting good lunar landing sites.
Coders on the International Space Station and at McMurdo base in Antarctica will join in.
The event runs from 21-22 April at more than 25 venues around the world. Hundreds of people have registered to go along and take part in the various challenges.
