A museum should give the science somewhere to meet people.

A museum or discovery space should be more than an attractive reception for commercial occupiers. We propose a programme that helps people explore how medicines are investigated, developed and used, including uncertainty and the people behind the work. The starting question is what a visitor should understand or be able to question afterwards. That purpose should guide the stories, objects and interactions before a dramatic architectural space or a technology-heavy exhibition is commissioned.

A travelling exhibition, workshop series or partnership with an existing venue may test the concept before a museum is built. We propose comparing these options with a permanent public-discovery component, including cost, reach, accessibility and programme maintenance. UKRI's public-engagement resources provide context for exchange between science and society (UKRI, n.d.). The Green Book provides appraisal context (HM Treasury, n.d.). These sources inform the questions; they do not establish an award, visitor forecast or economic impact for Constellation.

Attendance can show reach, but it cannot explain whether the experience was useful. A proposed pilot would investigate understanding, questions generated, accessibility and the relevance of the content to visitors' lives. Feedback methods should suit the audience and avoid implying a formal research study where none has been agreed. The useful output could be a revised programme with evidence of which stories work, where visitors become confused and what support makes participation easier.

Curation, staffing, accessibility, safeguarding, maintenance and programme renewal create continuing responsibilities. The proposed model would examine potential earned income, sponsorship and partnership arrangements as hypotheses requiring evidence. Research occupiers should understand the implications of public activity, and the public programme should have an accountable operator. We would not assume that ticket sales, sponsorship or public funding will cover a gap merely because the concept has cultural appeal or photographs well.

The bounded next step is a small discovery programme with a defined audience, experience and evaluation question. Continuation would require evidence of useful engagement, manageable operating effort and a credible reason for a permanent setting. We would stop or change format if the programme does not serve its audience, cannot be maintained or depends on unsupported demand assumptions. A capital discussion should connect public value and operating reality, preserving the ambition without presenting a museum as an assured financial return.
