Beginning with the September 9th, 2014 Peyton Hall meeting and going forward, the monthly meeting will commence at  7:30 P.M.

Atacama Large Millimeter/submillimeter Array (ALMA)

Enthusiasm for observational astronomy, curiosity about cosmology, achievements with CCD imaging and technology. These and all other aspects of astronomy are interests shared by members of the Amateur Astronomers Association of Princeton. The club is based in Princeton, (Mercer County) New Jersey.

This organization of 100 + promotes astronomy-related activities for members and non-members, novice to expert.  A wide spectrum of astronomy interests are explored at the AAAP through regular meetings, workshops, use of the two club observatories, public outreach and regional star parties.

Come explore our web site.  Here you'll find details about our organization's meetings, discussion topics, members and their scopes, and a lot more. Our organization maintains two observatories: the larger in Washington Crossing State Park (housing a research-grade 355mm Schmidt-Cassegrain catadioptric and historic 159mm Hastings-Byrne refractor). A second facility is found at Jenny Jump State Park in northwestern New Jersey. This houses a 318mm custom-built Newtonian reflector.

'What’s the Future of America’s Human Spaceflight Program with Orion and Commercial Astronaut Taxis'
by Dr. Ken Kremer of Universe Today, AmericaSpace and AAAP
Tuesday, October 14, 2014 at 7:30 p.m in Peyton Hall

Dr. Ken Kremer will present an eyewitness account of NASA’s future plans to resume launching humans to space from American soil aboard NASA’s new Orion and commercial capsules from Boeing and SpaceX to end our sole source dependency on Russia. Ken will give an inside account of NASA’s multipronged strategy and historic new decisions taken to develop private astronaut ‘space taxis’ to Earth orbit and for ambitious human expeditions to deep space with Orion to the Moon, Asteroids and Mars. Ken will discuss the critical upcoming Fall 2014 launches of Orion from the Kennedy Space Center, Florida and Antares/Cygnus from NASA Wallops Virginia in support of NASA’s human spaceflight objectives and the space station and how you can see them. Ken will briefly update NASA’s Mars rovers and orbiters including Curiosity and MAVEN. Ken will have a selection of his Space photos for sale.

Ken Kremer is a journalist, Ph.D. research scientist, speaker and photographer based in New Jersey. His space and Mars imagery and writings have been widely published on TV, magazines, books and websites including National Geographic, NBC, ABC, BBC and Fox News, PBS NOVA TV, Scientific American, APOD, NASA, Aviation Week, Astronomy, Astronomy Now,, Spaceflight Now, Spaceflight, New Scientist, Planetary Society, Popular Mechanics, AmericaSpace, Universe Today, NASA Watch, Wired, Science News, All About Space, NPR, Mars Society, International Year of Astronomy, 2010 Year in Space Calendar and the covers of Aviation Week, Spaceflight and the Explorers Club magazines.

September 2014 through June 2015 Monthly Meeting Season (at Peyton Hall)
Peyton Hall (right) is the location of the 2014 - 2015 AAAP monthly meetings. The building is home to the Department of Astrophysical Sciences, and is located just east of Washington Road, adjacent to Palmer Stadium, on the Princeton University campus.  Meetings are on the second Tuesday of each month and begin promptly at 7:30 PM in the lecture hall (first floor) of Peyton.   

Meetings start with brief announcements of general interest, followed by a guest speaker presentation.  After the guest speaker, the general meeting commences, reviewing current and future club activities, astronomy news, and public outreach projects.   Regular attendees of the lectures are encouraged to become paid members to support these popular speaking events.  Please email the AAAP for additional details.
Princeton University students also host a telescope open house at Peyton Hall concurrent to the end of our meeting. If the sky is clear, stop up to glimpse the universe.
