RAG Monthly meeting 28/6/2019

Our June ‘End of Month’ Meeting, this next Friday, 28th, has a ‘double bill’ in terms of Guest Speakers. The room was virtually full to capacity with folks sat on the tables at the back as well as on the chairs.

The beginning of the evening saw the return of Dr Martin Braddock. Many of RAG Members responded to his request for our ideas about the Five Challenges for the colonisation of Mars. Indeed, one of our Mid-Month Meetings held a discussion that produced a plethora of ideas to add to individual replies. Heather sent all these to Martin, who has now collated all his results from a number of Astro Societies. He came along to share with us the results – what is it that amateur astronomers think are the biggest issues facing potential colonisers on Mars? Martin is an exciting and knowledgeable speaker and he expertly addressed a number of questions from the floor afterwards, including some from yours truly!

After the coffee break, our very own Lee Bale continued with his series of talks on stars. Tonight, our brains got stretched somewhat as we tried to grasp how a nebulous cloud contracts into stars that join the main sequence on the Hertzsprung–Russell diagram. It involved learning about four different nuclear fusion pathways……..

Two excellent speakers – my only concern is that we are raising the bar on quality of talks so high that I ask how can we maintain it in the future?
