Professor Colin Pillinger CBE FRS, who was born and educated in Kingswood, started his scientific career as part of the University of Bristol team analysing the Apollo lunar samples.
He went on to spend four decades analysing, writing and talking about extraterrestrial objects - a famed career which found tantalising evidence of life on Mars.
The University of Bristol is working with his family to host the first Colin Pillinger Memorial Talk on 25 November, featuring leading speakers from the world of space exploration and astronomy.
Impressionist, comedian and amateur astronomer Jon Culshaw will host 'An Hour on the Moon', an illustrated discussion about our fascination with the Moon and the exploration - past and future - of our nearest neighbour in space.
Colin's widow Judith, who he met at the University of Bristol, said: "It is very fitting that we are able to hold the event in the city he loved. Colin was always ready to share his enjoyment of science with the public and we hope this annual lecture will carry on his legacy."
Speaking at the talk in the Wills Memorial Building is Dr Marek Kukula, public astronomer at the Royal Observatory, Greenwich, Dr James Carpenter from the European Space Agency, and author Peter Cadogan who worked on the Apollo samples in Bristol.
Additionally in Colin's memory, pupils at Kings Oak Academy, formerly Kingswood Grammar School where Colin went to school, will hear from a high profile scientist as part of plans to inspire young people to learn about space science and exploration.
Dr Matt Taylor, Rosetta Project scientist from the European Space Agency, will give a talk to the school on the Rosetta comet mission - a project that Colin played a pivotal role in.
- 'An Hour on the Moon', 6.30pm in the Great Hall, Wills Memorial Building, on 25 November. The event is free and open to the public, but tickets must be booked in advance. More information is available on the Public and Ceremonial Events website.
