Our Mission & Values
Our Mission Statement
The Royal Astronomical Society supports and connects astronomers and geophysicists, in the
UK and globally, throughout their careers. We assist them to sustain and advance the rigorous
scientific study of the origins and evolution of our own planet and the whole wider cosmos.
We promote a better understanding ofthe relevance and value of our subjects throughoutall
society, from inspiration for young people to advice to government.
Ourvalues
We are a supportive community
We are passionately curious about the universe, and recognise the importance of
mutual support in its study. We are custodians of the past, learning from the history of
our sciences but looking to apply our knowledge for the future. We promote the need for
vital research support, for appropriate collaboration and scrutiny, and forthe sharing of
methods and results.
We share our expertise in astronomy and geophysics
We are a respected, independent, self-governing organisation, free to speak frankty on
behalf of our members, the science and the profession. For over 200 years, we have been a
credible, independent source of the latest scientific discoveries in the field. Within our resource
limitations, we willingly prowde professional advice on all aspects of our subjects.
We are an inclusive and welcoming Society
We celebrate and encourage diversity, understanding that every individual is unique
and recognising and appreciating our individual differences. We will provide an inclusive
environment where every member of the Society is welcome and supported, and acts with
respect to all other members.
We play our role in understanding and protecting our environment
We care aboutthe future of humanity, the sustainability of our planet and the impact of
our activities. We seekto understand our role in the wider universe and use our knowledge
and expertise to the benefit of humankind.

A&G his account of pulsar science, from
the first detections through to current
observations and the future. It's a treat
to hear from someone whose career has
been atthe centre of things and whose
interests remain current. That his overview
sat alongside an appeal to ensure better
monitoring of the pulsars and other radio
transients thatwill be discovered bythe
next generation of radio telescopes gives
a snapshot of the breadth of research
interests among the RAS Fellowship. Last
but not leasi, the Editor thanks Fellows for

Political engagement
The Society continLJes irs work in public

association to Horizon Europe, which
eventually took place in September.
We welcomed the agreemenL which
meant that UK research groups could

support fromjanuary 2024.
The Society submitted written emdence
to the House of Lords Science and
Technology Committee inquiry into ￿ght

Light pollution continued to be an area
of concern. The Society gave evidence to
a Greater London Assemb￿ Enmronment
Committee inquiring into light and noise
pollution. The Mayor of London later
refused planning permission for the MSG

Early Career Network
At the National Astronomy Meeting
in Cardiff, the Ear￿ Career Network
Committee organised a career panel,
exploring the different opportunities
open to those starting out on careers in
astronomy and geophysics. Exemplifying
academic career paths, two of the
panellists were Rebecca Bowler, at the
Unwersity of Manchester, and Tana
Joseph, at the University of Amsterdam.
From industrywere Tim Waskett, who
does statistical research for Liverpool FC
and David Nutterof EDF. Afterall ofthe
panellists had introduced themselves,
there was a question-and-answersession,
allowing attendees to seekthe panel's
advice on the COU￿ of their careers.
For many eady-career researchers
who started during the pandemic, there
have been limited opportunities to meet
others in their position, and to forge the
connectionswhich will sustain them
throughouttheir careers. Forthat reason,
also at NAM, the Committee hosted a
networking lunch, which enabled ECRS
to establish new relationships, and
succe5sfulty elicited many questions
and much discusson.

RAS200
The bicentenary outreach project RAS200'.
Sky & Earth concluded in Februarywith
a meeting for all our partner5 followed
by a reTrption atthe Royal Institution
ir) London. The final evaluation report
fromjenesys gave an idea of the reach of
the project.. some 220,000 people had a
direct erngagementwith astronory and
geophysics through these12 projects.
That figure includes those attending an
event, workshop or presentation, as well
as those staff of our partner organisations
trained to deliver information about our
soences, and those watching events
online. The audience included those
already interested in our subject5, and
those with no prior knowledge or interest.
And the partner organisations the RAS
worked with meantthatwe engaged with
isolated adults, carers, prison inmates,
refugees, and young people outside
formal education, among others.
The success of the partnership model
used in RAS200 and, especial￿, the value
of systematic evaluation of the impact of
different aspects of outreach through the
different programmes, has been a benefit
of the project forthe RAS. Future outreach
activities will use a similar approach,
making the most olour resources.

The releases with the highest impact
included the NAM stories on ancient

resulted in at least 296 media articles

Grants Made to Councillors
The following grants were made to Councillors during the year as part of the RAS grant awarding process.
The recipients had no influence or part in the decisions on the award ofthese grants. For the most part the
grant holderswere notthe main personal beneficiaries as the supwrt was directty received bytheir students
or meeting attendees. Excluding Councillors from the grants round completely is not seen as a satisfactory
policy. Itwould Strang￿ dissuade members from standing for elertion as Councillor5 and would be aivariance
with the accepted practice in Research Councils where members of grants panels are not excluded from
appwing. The process of grant review and award fully complies wth the Nolan Principles and cloSe￿fOllOWS
Govemment Research Council practice.
The grants were..
Sir Norman Lockyer Memorial Trust as disclosed in note 22 (which shares the Same board of tru5tee5 as the
Society).
F A Paneth Meteorite Collection as disclosed in note 22. Dr Nigel Bemian, Treasurer, was a trustee, and Prof

When adopts'ng total applied return with effect from 1 January 2015, in the absence of reliable records of
the original donations, the trustees considered thatthe marketvalues of the investments as ￿cOrded as at
l January 2015 were approprk4te to be considered as the initial value of the trust for investment. Since that
figure sets the baseline below which disposals may not be made, taking a higher value than the actual original
donations was considered to be prudent.
The trusiees have res0￿ed thattheywish to maintain the ￿al value ofthe permanent endowment using the
retail price index as 3 measure. No transfers to the restricted funds were made in the year {2022- £nil).
