Another stellar line-up has been announced for Cheltenham Science Festival (June 4-9) which will bring together the best scientists, writers and thinkers to explore big ideas and answer big questions over six extraordinary days.

Highlights include Rick Armstrong remembering his father Neil Armstrong's 1969 mission to the moon. This forms part of a series of events marking 50 years since the Apollo moon landing, including an appearance by Britain's first astronaut Helen Sharman.

Bestselling author Matt Haig and CBBC's Operation Ouch presenter Dr Ronx are guest curators for the theme of Wellness featuring 30+ events.

The Festival's first A.I. guest curator AIDA presents 'Introvert Narwhals' having analysed 10 years' worth of Cheltenham Science Festival programmes.

Other contributors include Nobel prize-winning biologist Venki Ramakrishnan with Danielle George delivering the Royal Society Michael Faraday Lecture.

There are also hundreds of free activities for all ages in the free-to-enter Festival village in Imperial Gardens

High-profile campaigners and leading researchers will examine the evidence and shed light on the hotly-contested topic of Wellness. Bryony Gordon, Kate Humble, Claudia Hammond, Louise Minchin, Olympic coach Steve Ingham and Angry Chef Anthony Warner are joined by leading experts in sports science, medicine and mental health to reveal evidence-based life hacks and the latest research findings.

Uniquely curated events which can only be seen at Cheltenham include the International FameLab Final which will crown the world's best new science communicator; a look behind the scenes at Britain's Cyber Security agency (part of GCHQ) and live demonstrations of cutting-edge sports performance tests used on elite athletes.

Tim Hawking discusses his father Stephen Hawking's final book: Brief Answers To The Big Questions with a panel of physicists; Carol Vorderman commemorates 50 Years of Concorde, and for time-travellers there's an after-hours rave at the Dr Who Party.
