Book review: Haynes manual - Apollo 11
|
Christopher Riley, Phil Dolling (2009). NASA mission AS-506 - Apollo 11 - 1969 (including Saturn V, CM-107, SM-107, LM-5) - Owner's workshop manual - An insight into the hardware from the first manned mission to land on the Moon. Haynes Publishing, Yeovil, Somerset. ISBN 978 1 84425 683 9. Hardcover, 27.2x20.8x1.6 cm, 196 pages, several photos or illustrations per page. £17.99 rrp.
Riley is co-director of the documentary In the Shadow of the Moon, Riley and Dolling both are regular contributors to the BBC's science programming. Fortunately, they take the joke of writing a Haynes manual for a spacecraft instead of your real-life car no further than the cover. The book is about the technology that took astronauts to the Moon, and implicitly about the 400,000 humans that made it happen.
There are chapters about the Saturn rocket, the Apollo spacecraft proper (command and service module), and the Lunar Module. Other chapters deal with guidance and navigation, space suits, and the communication links. The text recounts the technology in simple terms and the history of the technological progress in good detail. As someone who on occasion will slot GBytes of RAM into motherboards, I like best the story of the Little Old Ladies ROM: Onboard software was stored in read-only memory, which was woven from copper wires and magnetic cores. Software was not patched by editing, the 32 kByte had to be tediously re-knitted.
The book is full of drawings and photographs, chosen for their information content and relevance to the technical description. Many photographs make you go "ah that's how it works", but you will probably not find these in other publications. Some drawings are difficult to read in detail, but this does not distract from the narrative. The book is about Apollo 11, including the entire Apollo programme leading up to it. Apollo 12 to 17 are dealt with only very briefly in the final chapter.
The appendices decipher the acronyms and provide tables of the missions and of the disposal of the various parts, from the Apollo 10 Command Module in London to the Apollo 10 Lunar Module in solar orbit.

Structure, governance and management
The Society is an unincorporated association founded (as the Edinburgh Astronomical Association) in 1924 and is governed by a Constitution most recently modified on 13 January 1995. The Constitution may be referred to on the Society's web site at http://www.astronomyedinburgh.org/constitution.
The Management of the Society is vested in a Council, elected from the Ordinary Membership of the Society at the Annual General Meeting (AGM). In the event of any vacancy arising in the Council, the Council has power to co-opt a Member of the Society to fill such a vacancy.
The Astronomical Society of Edinburgh Trustees
A former Vice-President of the Society, Mr John Henry Lorimer RSA, left a substantial bequest to the Society when he died in 1936. This bequest has been assigned to "The Astronomical Society of Edinburgh Trustees" and is managed by them under conditions set forth in a Deed of Trust granted in favour of Rev Dr James Patrick DD BSc and others, dated 10 December 1937.
The following are the trustees in terms of that deed:
- Mr Alan Pickup FRAS (Secretary and Treasurer)
- Mr Raymond Fenoulhet
- Dr David Gavine FRAS
- Mr Jim Nisbet
- Dr John Rostron
All of the above trustees are past Presidents and Members of the Society.
Astronomical Society of Edinburgh Trust is registered Scottish Charity SC013921.
Objectives and activities
Clause 1 of the Constitution is:
The name of the Society shall be "The Astronomical Society of Edinburgh" and its objects shall be to advance the education of the public about the science of Astronomy and to promote astronomical research chiefly in Edinburgh and its neighbourhood. In furtherance thereof:
- (a) to circulate information on astronomical matters by the publication of articles, books etc.;
- (b) to encourage astronomical study and observation; and
- (c) to increase popular interest in astronomy.
The Society continues to hold meetings throughout the year with educational talks on different aspects of astronomy. Practical observing has always been encouraged by the Society, with some members contributing to nationally coordinated observing programmes (through the British Astronomical Association), some producing interesting images to show at our meetings, and others supporting public observing for members and visitors alike.
Following an initiative of the International Astronomical Union (IAU) and UNESCO, the United Nations proclaimed 2009 the International Year of Astronomy (IYA). The Society supports this initiative. In addition to placing its monthly meetings under the IYA banner, it participated in several outreach activities during the year.
Achievements and performance
Membership
On 31 December 2009, the membership of the Society was 58 of which six were honorary members. Honorary members are Dr H. Ford MBE, Dr D. Gavine, Dr N. Grubb, and Prof D. Heggie. The Honorary Presidents are Prof Andy Lawrence BSc PhD FRAS FRSE (Regius Professor of Astronomy at the University of Edinburgh) and Prof John Brown BSc PhD DSc FRSE FRAS (Astronomer Royal for Scotland).
Meetings
The Council of the Society met on 16 January, 13 February, 3 April, and 14 August 2009. The Annual General Meeting was held on 13 March 2009. Nine Ordinary Meetings with educational talks on different aspects of astronomy were held; see "Optional information" for details.
Publications
Editions 59, 60 and 61 of the Society's Journal were published in 2009 under the editorship of Horst Meyerdierks. Members are encouraged to obtain their copy of the Journal from the Society's website, but paper copies are also available to members who prefer these. Paper copies are also sent to the Legal Deposit Libraries. International Standard Serial Numbers have been issued for both online and paper versions of the Journal:
- web: ISSN 1756-5111
- print: ISSN 1756-5103
The online version is available to the public at http://www.astronomyedinburgh.org/publications/journals.
Members are issued with the latest edition of the Federation of Astronomical Societies' "Astrocalendar" on payment of their subscription to the Society.
The City Observatory
In January 2009, the Society's Council decided that the City Observatory was no longer a suitable venue for our monthly meetings and that we would cease to occupy the City Observatory. During February and March 2009, the premises were vacated and assets of any notable value transferred to storage. Books and telescopes were moved to storage. Some magazines were given to interested members. Old issues of the Journal of the British Astronomical Association are held and will be posted to said Association. The remaining magazines and obsolete and deprecated equipment were disposed of.
The accounts reflect a change in spending. The cost of running the Observatory is much reduced in 2009 and will be zero in future years. On the other hand, we now have to hire storage and the venue for meetings. It is intended to sell part of the books and some other stored items. This will provide some further income in the short term and will reduce storage cost for the long run.
Observing, International Year of Astronomy, etc.
An arrangement has been made with a local organisation, which allows our members the use of a Dark Skies site. Members are being required to pay a deposit for keys to this site.
The Society held public observing sessions during the periods allocated by the International Year of Astronomy to the spring and autumn Moon watches. The autumn Moon watch was organised jointly with the Royal Observatory Edinburgh and on one evening also with the City of Edinburgh.
The Society participated in a 3-day festival "John Muir Odyssey", held by the Scottish Seabird Centre, North Berwick, which focussed on environment and outdoor pursuits and was part of the Homecoming Scotland events. In addition to a stand offering handouts and fielding questions, on two days we were able to show the Sun in Hα light, the planet Venus in the daytime sky, and the Moon.
A few members of the Society provided minor assistance - IT and operating a telescope - to an event in the Edinburgh Science Festival, which was organised by Lorna McCalman, Charlie Gleed, and Prof John Brown, who are members of the Society.
The Scottish Solar System (http://www.scottishsolarsystem.org.uk) has assigned the minor planet (153) Hilda to the Society.
Financial review
Similarly to last year, and as expected, the Society has incurred a high deficit of £2,530 on our income and expenditure statement. This is not as dire as would at first sight appear. In keeping with previous years, our decision last year was to continue with the policy to defer receiving the interest accrued on investments held by the Trust. The deferred income due to the Society has instead been invested by the Trust on the ASE's behalf in dedicated investment bonds which have yielded a far higher rate than the ASE has been able secure in the past.
As a result, it is estimated that a backlog of around £7,500 has accrued over the five-year period since interest was last paid to the Society.
However, for the first time since 2005, we will be requesting from the Trust additional funds for 2010.
Our expenditure for some areas has increased this year whereas other areas have decreased. Overall, there has been a net increase in expenditure this year compared to previous years. The reasons for this are the high storage costs amounting to £1400 for the year to 26th March 2010 and secondly due to the cost of meeting room hire at £490 for 2009. During 2010, our estimated storage costs are expected to drop to £927 per annum as we reduce the storage space requirements taken up by the Lorimer chairs from the Playfair Building along with other bulky items. The cost of room hire is expected to be around £850 per annum.
On the other side, all costs associated with the Observatory, mainly electricity and some of the Observatory vandalism repairs have now reduced to zero. In addition to this, our contents and public liability insurance has now decreased significantly from £657 in 2008 to £359 in 2009 due to migration away from Royal Sun Alliance to a policy provided by the storage company and with public liability insurance now being provided by the Federation of Astronomical Societies. It is expected the total insurance costs will reduce in 2010 to no more than £220.

- D1: ASE annual subscriptions
These are considerably lower this year (£743) compared to last year's unusually high figure (£1,237). The reason is that during 2008 many people paid late due to lack of reminder being sent. Hence the figure for 2008 contains subscriptions for both 2008 and a large proportion of 2007. Annual subscriptions are now our main source of income excluding the income from the ASE Trust. - D2: Meeting expenses
Meeting expenses include room hire, speaker's hospitality and expenses. This is higher than last year mainly due to the cost of room hire but offset due to reduced speaker's hospitality requirements in 2009 compared to previous years. - D3: Magazines and subscription
Due to the lack of library facilities the Society has cancelled subscriptions to astronomical magazines from previous years e.g. Sky & Telescope, BBC Sky at Night, Astronomy Now and Practical Astronomer. - D4: Membership and affiliations
Currently, the only affiliation the Society has currently is the Federation of Astronomical Societies. The FAS has now changed its membership year and therefore no payment was required in 2009. - D5: Communications, including Journal
The large increase in cost of communications during 2009 was due mainly to the purchase of long-life toner for the Society's laser printer (£235) and also the renewal of the Society's 'Internet Domain Name' for a period of 8 years (£98). Other costs were Postage, stationery and Skype renewal (12 months). - D6: Dark Sky Site
Payment for November 2009 to November 2010 for the Society's use of the Dark Sky site at the West Calder Model Flying Club. - D7: Astrocalendars
The cost of Astrocalendars for the 2009/2010 session has been reduced by half resulting from a price reduction from the FAS. All ASE members receive an Astrocalendar on payment of annual subscription. - D8: Equipment
A padlock was purchased for the rented storage unit at 'Safestore'. - D9: Storage rental
Storage rental in 2009 was by far the largest item of expenditure to the Society. The cost of £1,408 is for 75 square feet for a period of one year. For 2010, we will be reducing the storage requirements to 35 square feet due mainly to transfer of thirteen Lorimer chairs formerly in the Playfair Building Library to Lorimer's ancestral home of Kellie Castle in Fife. An estimate of £927 per annum prior to any discount has been quoted by the same storage company 'Safestore'. - D10: Insurance
Contents and public liability insurance was previously with Royal Sun Alliance and this cost £657 per annum in 2008. The Royal Sun Alliance policy was cancelled in March 2009. The contents insurance is now with the storage company 'Safestore' (£187) and the public liability insurance (£28) is with the Federation of Astronomical Societies. - D11: Observatory migration
These costs are associated with one-off packaging required for removal of the ASE's assets to storage. Storage containers and bubble-wrap specifically. - D12: Electricity
Observatory electricity final bill up to the end of January 2009. - D13: Gas
Observatory gas final bill up to the end of January 2009.
Declaration
The receipts and payments accounts presented on pages 12 to 19 were approved by the Council of The Astronomical Society of Edinburgh (the trustees of the charity).
Independent examiner's report to the Council of
The Astronomical Society of Edinburgh
Editor's note: Due to extraordinary workload, the independent examiner did not complete the examination before the Journal going to press. In the circumstances, and to comply with the constitutional notice period for the Annual General Meeting and the distribution of the statement of accounts, this Journal is sent out without the examiner's report. The report will be tabled at the Annual General Meeting.
International Astronomical Youth Camp
The International Astronomical Youth Camp (IAYC) 2010 will take place in the small town of Klingenthal in the East of Germany from 1st to 21st August 2010. Klingenthal (9,000 inhabitants) lies in the region called "Vogtland" which forms the geographical border between the two German federal states Bavaria and Saxony. The nearest large towns in the surrounding are Hof in Bavaria (45 km), Plauen in Saxony (30 km) and Karlovy Vary in the Czech Republic (40 km). The camp house itself will be a very pleasant youth hostel called "Jugendherberge Aschberg", right on the border with the Czech Republic (5 m).
The IAYC is an international youth camp with participants from about 20 different countries. As a participant you work for three weeks in one of the 7 working groups - together with other young people - on astronomical projects. The projects vary from night-time observations to theoretical problems, depending on your own interests. The working groups will be led by young scientists from the IAYC team. The IAYC 2010 will offer a wide range of working groups and topics, ranging from practical astronomy and basic theoretical astronomy over simulations in astronomy and electronic-robotronic engineering to high energy astrophysics, astrochemistry and not-so-introductory physics. There will be something for everyone from the complete beginner to the ambitious student.
As well as the astronomical program, there are many non-astronomical activities such as group games, sporting events, singing evenings, hiking tours and an excursion. Since it is an international camp, the camp language is English. You should be able and willing to speak English throughout the camp. It is not necessary to speak English fluently.
Anyone from 16 to 24 years old and able to communicate in English may participate in the IAYC 2010. The fee for accommodation, full board and the whole program, including the excursion, will be €620. However, early applications arriving before April 15th 2010 receive a €30 reduction, making the camp fee €590. For interested persons who are in the situation of not being able to pay the camp fee themselves, a limited number of grants is available.
Detailed information about IAYC 2010 has been made available at http://www.iayc.org. If you have any questions or wish to be notified when more information becomes available, please contact:

Solar minimum
The diagram on the title page shows the sunspot number for the years around 2008/2009. The horizontal axis is a day counter known as the Julian Date (here minus 2,450,000 days). The sunspot counts on the vertical axis are calculated as the total number of spots plus ten times the number of sunspot groups. The red curve shows the International Sunspot Data, which are the continuation of the Zürich sunspot numbers, which go back to the middle of the 19th century. The green curve shows my own counts, which have been reported to the British Astronomical Association, and the blue curve shows the collated data from all BAA observers. For all three curves the daily spot counts have been averaged first over 30 days and then over 9 such 30-day periods.
Since the 18th century, solar activity has been going up and down in cycles that are on average about 11 years long. A minimum of sunspot numbers is overdue, but even the 9x30-day averages are not smooth enough to be sure of the minimum until quite some time after it has happened. The graphs include data up to November 2009, and only around that time can we have at least some confidence that the minimum has occurred. The time of minimum seems to have been in November or December 2008.
During the second half of the 17th century there was a lengthy period of low solar activity. With the current minimum occurring rather late, there have been worries that another long period of hardly any sunspots might be starting. It is still too soon to be certain, but the data are still consistent with a normal rise of sunspot counts between now and another maximum around 2013.
Society news
At most Ordinary Meetings Alan Pickup gives a presentation about the sky in the forthcoming month, usually including snippets of recent news in the fields of observational astronomy and spaceflight.
On 2009-11-06, Catherine Smith demonstrated that a mathematician and banker with a working-class background might well write a biography of Robert Burns: Credit crunch, famine, climate change, they had it all in Burns' lifetime. Burns learnt astronomy as a young farmer's son and kept a life-long interest in science as well as arts. On 2009-12-04, Douglas Cooper presented some of his stunning astrophotographs and gave some pointers how to go about imaging the night sky. In January, Melvin Taylor was in town for the annual exhibition of Turner watercolours, and made some "confessions of an amateur observer" on 2010-01-08. For 2010-02-05, Ettore Pedretti had to step in at short notice to report on the technological challenges and recent successes of optical interferometry in seeing detail on stars. Des Loughney gave an interesting talk on 2010-03-05 about the currently eclipsed star ε Aurigae, emphasising the importance of amateur observations.
Imaging group
The imaging group has re-formed and held its first - well attended - meeting on 2010-02-24 in Juniper Green. This group is for members interested in using cameras and imaging devices in amateur astronomy, beginners and experienced imagers. Watch out for announcements of further meetings.
