Two-day hackathon underway in Dublin

It's Science Hack Day and some of Ireland’s best software designers, coders and engineers have gathered in UCD for a two-day-all-night hardware and software hackathon.

It's also taking place in over 20 countries around the world.

Ariel Waldman, its Global Director, joined Neil in studio to tell us more about the event.

She sits on the Council for NASA Innovative Advanced Concepts.
