Volume 38 From the Director

September

Number 9

The weather so far this summer has not been very conducive to astronomy. High humidity, clouds and thunderstorms (nothing unusual there) have hampered the viewing. However, at Stellafane on August 13-16, for the first time in memory (my memory anyway), we had three good nights of viewing. Thursday was clear but very dewy. Friday was clear until about midnight when some clouds rolled in (they cleared out later). Saturday was clear from dusk to dawn. And it didn't rain at all for the entire convention (another first). I had my new 15" f/4.2 Dobsonian with me. This is the biggest scope that I've ever owned and under the good dark skies at Stellafane it really performed. I saw some things that I've never seen before: Pickering's Triangular Whisp (the dim central part of the Veil Nebula), spiral structure in M51, The Trifid (M20) as a three lobed structure and extraordinary detail in the great globulars M13, M92, M5 and M3. In addition the main speaker at Stellafane this year was Capt. Alan Bean, the lunar module pilot on Apollo 12 and the fourth man to walk on the moon. He gave an inspired talk on the past, present and future of space exploration. All in all this weekend went a long way towards making up for the dismal weather we have had so far this year. On Thursday August 20th we had our first meeting of the board of directors this year. Following are some of the topics that were discussed. Our first meeting of the year will be on Sept. 8th at 8 PM at Peyton Hall on the Princeton campus. The speaker will be the AAAP's own Dr. Ken Kremer. His talk is titled: "Eyewitness to LRO & LCROSS: America Returns to the Moon ". We are still looking for speakers for the remainder of the fall. To this end we are still without a Program Chairperson. If anyone is interested it this important position contact me.

By the time of the September meeting the repairs to the Simpson Observatory should be complete. We will be voting before the speaker presentation to appropriate the funds to cover this repair. Details about this repair were published in the mid-summer issue of the Sidereal Times along with an absentee ballot. It is important that we have a sufficient number of votes (40% of our membership) in order to be able to do this according to our by-laws. If you can't make the September meeting please get a copy of the absentee ballot at www.princetonastronomy.org and mail it in by Sept. 4th.

The deadline for the October issue is: Friday October 2, 2009 Send your submissions to: editors@princetonastronomy.org
In addition to the repairs to the Simpson observatory our observatory at the UACNJ complex at Jenny Jump is in need of repair as well. The door needs to be replaced and the observatory needs to be painted. Larry Smith has undertaken to get a new door (Thanks, Larry) and have it cut to size. At the meeting in September we will set a date for a work party to install the door and paint the observatory. If you remember last year the NJ Park Service floated the idea of building a cabin for reservation camping at the bottom of Brickyard Rd. in Washington Crossing Park. This idea was shot down at an angry meeting of Hopewell township residents but unfortunately (article in Trenton Times August 20th) it has raised its ugly head again. Now the Park Service wants to build a cabin for 30 campers (the original cabin was for only 8 campers) in the current camp site used by scouts off the soccer fields inside the park. Potentially, this cabin could have a severe negative impact on our observatory. The board is in the process of writing a letter to the DEP to express our concerns. We are tracking this issue and will keep the membership informed as to developments. The new flyer containing information and prices for Starquest 2009 has been completed and should be available, by the time you read this, on the AAAP website.

Amateur Astronomers Association of Princeton Secretary Report: Kane reported three new membership applications and some bills that he passed on to the Treasurer. Observatory repairs: John Church reported that most of the work has been completed. John has provided much assistance to the contractor in the repair work. The final bill should be presented by September 8. It was noted that we need a Program Chair. The speaker for the September meeting will be member Ken Kremer. John Church offered to ask member Freeman Dyson to give a talk at one of our meetings. He also offered to do a presentation of a recorded transit that he made. Observatory: We that it was the park was agreed that the of using a chain wit need more key-holders. John Church reported workers that were leaving our gate unlocked. It combination will be changed and the old method h a lock at each end will be re-instituted.

Black Forest Star Party (Sept. 18th-20th) For years I have been trying to get out to Cherry Springs State Park in Coudersport, PA. This is supposedly the darkest site left in the northeastern US. (It has been designated an official dark sky sanctuary by the US Park Service.) I will finally get the chance at this premier star party run by the Central Pennsylvania Observers. See their website at www.bfsp.org/starparty for further details. Jersey Starquest 2009 This year's Jersey Starquest will be held at the Hope Conference Center in Hope, NJ on Oct. 16-18. Bring your scope to enjoy a weekend under the stars in northern New Jersey. I'll have my 15" Dob with me for anyone who wants to take a look through it. Bill Murray, Director

Minutes of AAAP Board of Directors Meeting August 20, 2009
The meeting was called to order by Director, Bill Murray. John Church raised the issue of the State plan to build a thirty-bed "cabin" in Washington Crossing Park. Gene Ramsey reported that it is planned to be built next to Brick Yard Road. He spoke with Wayne, the park ranger who is our club's contact with the park. They discussed access to our observatory and the nature center for those using the cabin, as well as matters such as additional lighting, noise and security. Access to the cabin would be via Bear Tavern Road near the soccer field and would likely, require the construction of a new access road, around our inside gate. Mr. Donnelly, the Park Superintendent told Gene that ground breaking would be in three to four years. Ludy D'Angelo suggested that the AAAP write a letter to the State DEP expressing our concerns and raising these issues. Mike Mitrano pointed out that this new cabin is a settlement that the State offered to the residents of Titusville who objected to the original plan to build a cabin, and that our group may be alone in its objection. Gene pointed out that the original cabin was supposed to house eight people and the new one is supposed to house thirty. It was suggested by Larry Smith that the letter should go above the superintendent level to someone in a position to make a decision. Gene and John Church pointed out, that we have a good working relationship with the superintendent and our letter should go up the chain of command. Mike Mitrano suggested that there are planning committees within the State structure that make these capital outlay decisions and that we should address our concerns to them in a timely enough manner to have a positive effect. Larry Kane will write a letter to Donnelly and run the draft by the Board members. Larry Smith suggested that the planning group be copied. Ron Mittlestaedt said that cut-off lighting could be installed outside the cabin that would lessen the impact on our observing. Treasurer's report. Mike Mitrano reported that there have not been a lot of expenditures lately. The treasurer's report is found is another section of this edition of the Sidereal Times.

Star Quest: Bill Murray presented a flyer that was developed by UACNJ. John Miller thought that the UACNJ was usurping the Star Quest event. A question was raised about what the UACNJ was planning to present. Larry Smith thought that anything we will get from their promotion of a mutual event will be a benefit to us. Larry Smith said that he will re-send an email concerning the pricing of the UACNJ event. He stated that UACNJ offered to have a couple of their speakers come to our event. Bill Murray noted that originally, Star Quest was a members only event and that when it was first opened to the public, there was good response but it has dwindled, since then. Larry Smith said that the UACNJ event will be over by 9:00 pm on Saturday night. It was thought that the people would then leave, and drive down to our event, after dark, and flood the viewing field with white light. A discussion was held about establishing a cancellation policy for bad weather. A discussion was held about whether to continue with Star Quest and whether it actually raises money for the Club and whether that is what we should be doing. It was noted that the most important part of the event is the observing that we can do. John Miller suggested that last year's flyer is on our website and it should be downloaded and suggestions for revisions made to him. Larry Kane requested that the finalized flyer be brought to and distributed at our September meeting. Jenny Jump Observatory: The door needs to be replaced. Larry Smith said he could buy one from Home Depot and a UACNJ member offered to make a door for us. Bylaws Revisions. Mike Mitrano recommended changes that will make it easier to pay for needed expenses. Other structural and procedural changes were suggested. It was noted that we have a separate constitution and by-laws. John Church said that this was done so we could revise the by-laws without having to revise the constitution. Mike Mitrano will write up all the suggestions made at this meeting and will send it to the Board for its consideration. The revisions will be raised at the September meeting. Observatory Teams: Ludy made a recommendation that observatory team two be disbanded. A discussion was held about key-holders letting their team know if they cannot make an assigned night. The meeting was adjourned by the Director. Larry Kane, Secretary

September 2009 3000 ly away and spans 50 ly across. This picture was taken by me from Coyle Field in southern NJ this past month.

Treasurer's Report
Our fiscal year began on July 1, and there has been little activity over the summer. Dues payments from nine members have been received (thanks!) along with $150 from outreach and equipment sales. With few expenses, our surplus since July 1 is $357. Because the Observatory repairs have not yet been completed, those expenses are not finalized or reflected here. The AAAP's cumulative surplus is about $18,500. Michael Mitrano, Treasurer

September's Speaker
Eyewitness to LRO & LCROSS: America Returns to the Moon" by Dr. Ken Kremer, NASA Ambassador and The Planetary Society. NASA re-ignited the US `Return to the Moon' in June 2009 with the launch of two new science spacecraft, the Lunar Reconnaissance Orbiter (LRO) and the Lunar Crater Observation and Sensing Satellite (LCROSS). Take an up close and personal tour of the robotic duo with Dr. Kremer inside the "Clean Room" for the last look before blast-off with top NASA scientists and learn about the science goals. Journey inside the Air Force rocket base at Cape Canaveral to see the Atlas V rocket at Launch Complex 41 which propelled the probes to space and set LCROSS on course for a cosmic smack-up into the moons South Pole on 9 October 2009 in search of water. Dr. Kremer is a research scientist and science journalist whose articles and space exploration images have appeared in magazines, books and on websites, including Astronomy Picture of the Day, ABC News, Spaceflight Now, New Scientist, International Year of Astronomy, The Planetary Society, Universe Today and the covers of Aviation Week & Space Technology, Spaceflight and the Explorers Club magazines. His numerous presentations at educational institutions, civic & religious organizations, museums and astronomy clubs aim to educate and excite kids and adults about science and space exploration. For complete details on LRO and LCROSS, please read Ken's published reports which can be found online at The Planetary Society and which include pictures of the spacecraft and rocket. The speaker can be reached at kremerken@yahoo.com. Or at the Website http://www.rittenhouseastronomicalsociety.org/Dr.Kre mer/K.htm We are all around; you just have to look for us My family and I went to Gettysburg this summer as one of our getaways. We took our camper down to stay in a local campground for a few days. After getting things set up and venturing around to check out the campground I noticed the license plate on the car at the site next to us. It read Piedmont Amateur Astronomers. Well what do you know. I kept an eye out for our neighbor to venture back to their sight and introduced my self to him. He and his wife were from North Carolina and go to several of the larger star parties around the country. We talked from scopes to eyepieces to public outreach and such. It turns out he is his clubs editor for their monthly publication too. After coming back to NJ I sent him the same M20 image I submitted for this months Sidereal and said if he could use it in his paper to please do. It just goes to show you, you never know who is around you unless you advertise a bit. Brian Van Liew

Other News... Picture This--The Trifid Nebula
Also known as M20 this colorful nebula is a mere gray patch visually in NJ. Located in Sagittarius, this gaseous cloud sits just above the Lagoon Nebula and below the Swan and Eagle Nebula. From a dark sight this can easily be seen in a simple 8x50 finder scope. This Nebula consists of a reflection nebula which is the blue portion which is lit up from a nearby star shining through the gas cloud, while the red portion is emitting H-alpha light. Located in front of the nebula you can make out dust as dark areas. The Trifid is some

The Lunar Globe and Apollo VIII
If you happen to be lucky enough or if the stars are aligned properly in your favor, you might land a job, that if you could do it forever, you would run to it each day, and resign yourself to going home each night. In 1968, assigned to the Special Events Unit at CBS News, I found myself among some of the most talented people in the business. It wasn't a plumb job because it was easy. It was a plumb because it was hard and mentally challenging. The hours were, on occasion, very long and some of the deadlines very short.

September 2009 Before I became part of the unit, CBS covered all of the important NASA missions, not only for their scientific value, but also because of the political nature of the program. The space race was at full throttle. It was a time of full mission coverage. From preparation to launch and return, we were on the air for long hours. In December of 1969 Apollo VIII was about to go to the far side of the moon. It was a gift to America on Christmas Eve. On board were Frank Borman, James A. Lovell, and Bill Anders. Following launch, the rocket would be beyond the capabilities of television cameras. This was all before onboard cameras. Even with powerful telephoto lenses, the main engine plume was all that was visible at times. To overcome this limitation, CBS invested in animations that simulated real time events with the live voices of astronauts reporting in to mission control. The animation was in exact synchronization with the actual event. Everyone in our control room was ecstatic. It was damn exciting. My small part in all of this was to find a relief globe of the moon, which we used to illustrate the astronaut's lunar approach. The globe had to be in high relief with close attention to detail. Hmm, where to begin? I began by calling every important scientific institution, worldwide, asking for information concerning a lunar globe. Everyone was helpful, but to no avail. Knowing that the Russians were the first to photograph the far side of the moon, I called Moscow. Someone might have a lunar globe. One shouldn't expect much from your country's archenemy I got a very succinct reply, "Nyet!" Oh well, I tried. I then started to call locally. My first call was to the Hayden Planetarium. Had I started there, CBS would have had a much smaller telephone bill. Someone forwarded me to Dr. Thomas Nicholson, an astronomer and director of the planetarium. What a break. After a very cordial and interesting conversation, Dr. Nicholson remembered hearing about some guys in the Bronx who were working on a lunar globe. THE BRONX? I called Moscow, for-crying-out-loud. It was true. A very accurate lunar globe existed in THE BRONX. What a coup! CBS invited Dr. Nicholson to our studio, and along with our very talented lighting director, lit the one and only lunar globe exactly as the Apollo VIII astronauts would see the moon from the window of the command vehicle. From that prototype globe, duced versions of the lunar on the base of its pedestal moon is sitting on my desk back forty years. the company, Educational Frontiers proglobe for libraries and schools and right it says, "Bronx".

Amateur Astronomers Association of Princeton Wake up and smell the coffee--on the Moon! Have you ever wondered how you'd make your morning cup of java if you lived on another planet, or perhaps the moon? That steaming beverage would be a must on a cold lunar morning. But with rare sunlight, no coal or wood to burn, and no flowing water for hydro-electrical power, how would you make that cup of coffee, much less cook breakfast, heat your abode, and power the life support equipment and tools you needed to live and work up there? NASA, planning for a future lunar outpost, has been asking those same questions lately.

There's more than Surface Power is method is chosen, brothers Robert an

one way to generate power on the moon. Fission one of the options NASA is considering. If this an engine invented in the early 1800s by Scottish d James Stirling could help make it work.

[Editor's note: If you have questions about this technology, please contact Marshall Space Flight Center Public Affairs at 256 544 0034.] The Stirlings were so proud of their creation that they made it their namesake--and with good reason. Over the years the Stirling engine --the reliable, efficient "little engine that could"--has earned a sterling reputation here on Earth, and it may one day prove its worth on the moon. "Inhabitants of a lunar outpost will need a safe and effective way to generate light and heat and electricity," says Mike Houts of NASA's Marshall Space Flight Center. "The tried and true Stirling engine fits the bill. It's not only reliable and efficient, but also versatile and clean." NASA is partnering with the Department of Energy to develop Fission Surface Power technology to produce heat and feed it into a Stirling engine, which, in turn, would convert heat energy into electricity for use by moon explorers. It's not certain that this kind of power system will be adopted by NASA, but it does have some very appealing qualities. Houts explains: "A key advantage to this power system is that it wouldn't need sunlight to operate. An FSP system could be used to provide power any time, any place, on the surface of moon or Mars. It could be used at the poles and away from the poles, it could weather a cold lunar night, and it would do well in places like deep craters that are always shaded. Not even a swirling, sunlight obscuring, Martian dust storm could stop it." Submitted by Bryan Hubbard
