Our Society

The British Interplanetary Society is an international membership society and registered charity.

We are devoted to initiating, promoting and disseminating new concepts and technical information about space flight and astronautics.

Our membership

Our membership brings together those who work within the space sector, those with a personal interest in space, and those who are studying space exploration related subjects.

Membership is open to all with an interest in space.

Our location

The BIS’s headquarters are located in Central London, within 5 minutes walk from Vauxhall Underground, Rail and Bus Stations – enabling easy access for visitors to the Society.

We also have International branches.

Our Leadership

The Society is led by a Chief Executive Officer, who runs a team of 4 staff that deal with the day-to-day running of the Society, and oversees a volunteer workforce from within the BIS Membership.

Our Council

The Society is led by a Council of 12 BIS Fellows, who are elected for a 3 year term at the AGM.
The Council Members act as both the Directors and Trustees of the Society.

They are also the primary decision-makers for the BIS.

Our Committees

Committees of the British Interplanetary Society are run by BIS Members and Fellows on a voluntary basis. 
Each Committee focuses on a specific area of work, and often take an active role in delivering the objectives of the Society and organising projects. 

Non-executive Committees are open to any member. 

Our Branches

The Society has local branches across the Globe. 
We are always looking to grow and support local groups.
