There
are a few ways to use chemistry to power a rocket, but all involved an
oxider and a fuel. And with no oxygen in space, what’s the best
solution? Professor Andrea Sella from University College London
discusses the solid state boosters of the space shuttle, the cryogenic
liquid approach used in the 1970s, and demonstrates to dramatic effect
the power that hypergolic reactions can provide.

Hypergolic
mixtures spontaneously ignite, remove the need for a spark in space, and
give a huge relative reaction. Andrea combines nitrogen dioxide and
dimethylhydrazine to demonstrate how just a tiny amount of these
substances can pack a powerful punch.

‘A Place Called Space’ is
the 2015 Royal Institution advent calendar. Every day in the run up to
Christmas we'll be releasing an original piece of content exploring the
human experience and cultural significance of space travel. With
hand-drawn animations, experiments in zero gravity, interviews with
astronauts and creative data visualisations, the calendar will fire you
into space every morning.

'A Place Called Space' channels the
voices of seasoned astronauts and expert scientists through the eyes of a
team of talented animators, film-makers and artists, bringing you a
thought-provoking gem to kick-start each day.
