Group leader:Colin Brown
Tel:01923 285686
Meeting Venue:Members' homes
Time:4th Tuesday of the month at 2:30pm

New members are welcome. If you would like to know more about our solar system and the wider universe, are interested in the technology of spaceflight, or are intrigued by the occasional space stories that appear in the news, come along to one of our meetings and see whether you would like to join us. Don't be afraid of appearing ignorant. In the face of such a huge and rapidly evolving subject we all feel ignorant, but we're there to learn.

Next meeting: We are currently taking a summer holiday, and expect to start again in October.

Video below

Starts with a brief reference to a recent SpaceX launch, including video of a rocket fairing being recovered for re-use. However the main content is RocketLab's recent volte-face in deciding to pursue re-usability. After discussion of the logic behind the decision and the special challenges RocketLabs will face, there are some interesting comments on the slimming-down now visible in the overcrowded small rocket launcher market.

RocketLab and reusable rockets
