This report gives an overview of the Longitude Explorer Prize, a challenge for young people aged 11-16 to use satellite data for social good. It covers the following areas:

• Overview of the challenge journey (events, prototyping and feedback)
• Need for STEM education.
• Ideas submitted by schools and activities that children were involved in.
• Announcement of the winner and two runners-up.
• Evaluation of the Prize.

The main aim of the Prize was to encourage social innovation among young people and to promote STEM education. From apps customising outdoor workout programmes to devices monitoring ecological status of a local watercourse, read the report to see what ideas pupils came up with (p 18-19).

The Longitude Explorer Prize was designed and delivered by Nesta's Challenge Prize Centre in partnership with Winton Charitable Foundation, UK Space Agency, Raspberry Pi, Satellite Applications Catapult/National Space Academy, StemNet, Ignite Futures, Technopop and others.
