    CAPE CANAVERAL AIR FORCE STATION, FL – Production and assembly of virtually all the key hardware elements for NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight later this year are nearing completion at the Kennedy Space Center .

    Two of the three first stage boosters comprising the mammoth Delta IV Heavy rocket that will propel Orion to high Earth orbit have arrived at Cape Canaveral Air Force Station, Florida, and were unveiled in mid March by top NASA managers at a media briefing I attended at the Cape.

    The triple barreled Delta IV Heavy rocket is currently the most powerful American rocket and the only one capable of launching the Orion EFT-1 capsule to its intended orbit of 3600 miles altitude above Earth.

    Due to urgent US national security requirements, the maiden blastoff of the unmanned Orion pathfinder has just been postponed three months from September to December 2014 in order to make way for the accelerated launch of recently declassified US Air Force Space Surveillance satellites.

    The center and starboard side boosters recently arrived at the Cape aboard a barge from Decatur, Alabama where they were manufactured by United Launch Alliance (ULA).   The remaining port side booster and the Centaur upper stage are due to arrive in mid April.

    From the Director

    By Jeff Bernardis, Director

    I’m always intrigued by new discoveries, and many times, it’s the method of discovery that grabs me more than the discovery itself.  An example of this is the detection of exoplanets.  While I like to imagine what the planets themselves are like, it’s the ingenuity behind the discovery that I admire.

    Imagine my interest when in one single announcement a few days ago, NASA announced that it had confirmed the existence of 715 more exoplanets – all scoured from two year’s worth of the data that the Kepler mission had brought home.  There is still another two years of data to comb through, so who knows how many more they will find? These additional planets nearly double the number of exoplanets we have discovered – all in a single announcement.  Perhaps the most intriguing aspect of this discovery is the conjecture that as many as 20% of these planets could support life.  I’m a firm believer that life is out there somewhere. Knowing that life supporting conditions could exist elsewhere obviously strengthens that belief.

    Of course, my question is “How did they do it?”  All I have been able to find out to date is that they used a technique called “verification by multiplicity”.  It seems to be based on the fact that orbital perturbations previously observed and attributed to star interaction is now considered too stable to be caused by stars; hence, the conclusion that the perturbations are caused by multiple planets.  I’d sure like to know more about it – maybe a future speaker…

    Believe it or not, we are nearing the end of the current club year.  We need to start thinking about upcoming elections.  Our by-laws call for the appointment of a nominating chairperson at the March meeting.  Nominations would be announced in April, and the election itself would be in May.  I brought this up at the last meeting, and nobody has as yet volunteered for the nominating chair.  If you would be willing to take on this task, please send me an email or let me know at the next meeting.

    Chasing Shadows for Planetary Science

    by Michael Wright

    Ted Blank

    Credit: Ted Blank

    On March 20, 2014 at approximately 2:06 a.m. EDT the shadow of 163 Erigone cast by Regulus will race across the New York metropolitan area on its way to Ontario.  If skies are clear, observers within the shadows path will see Regulus disappear for up to 14 seconds.   Never before will so many people have the opportunity to witness an asteroid occultation of a star with their naked eyes.

    Ted Blank of the International Occultation Timing Association will present Chasing Shadows for Planetary Science at AAAP’s next meeting on Tuesday, March 11, 2014.   Ted will not only tell us how and where to observe the occultation; he will tell us how we can contribute to science by timing the event with any camera able to record video.  Princeton is a short drive outside the shadow path so amateur astronomers could discover moons of 163 Erigone by timing the event from New Jersey.  As usual, the lecture will begin at 8:00 p.m. in Peyton Hall, 4 Ivy Lane, Princeton followed by a business meeting.

    Ted Blank is a member of the International Occultation Timing Association (IOTA), a group of professional and amateur astronomers collaborating to promote scientific research by recording and analyzing the occultations of stars by asteroids and the Moon. He is the current President of the New Hampshire Astronomical Society and is in his fourth year as a NASA/JPL Solar System Ambassador. He enjoys Sidewalk Astronomy and public outreach, chasing the shadows of asteroids and observing from dark places with friends.

Shortly after 2:05 am EDT on March 20, 2014, observers between the red lines have the best chance of seeing the bright star Regulus temporarily disappear as asteroid (163) Erigone passes in front of it.

    From the Outreach Chair

    by David Letcher, Outreach Chair

    We are looking at star parties that have been arranged for May and October.  In May, we will participate in “Super Science Saturday” which will occur during the day of May 3rd. As usual, volunteers will set up their telescopes on the concrete apron between the State Museum and the State Library. Maybe there will be a few sunspots! I’ll be sending out reminders and further details to you in the near future.

    In October, we have been invited by the folks at the N. J. Audubon Society’s Plainsboro Preserve to set up telescopes during the evening of Friday, October 24 to allow children and their parents to view the heavens. The rain date is October 25. This date seemed to be good not only for them but for a new moon.

    I have not heard from any school teachers yet this season, but we will probably get some invitations from schools such as Princeton Day School. We’ll see.

    In the meantime I wish you clear skies!

    Treasurer’s Report

    by Michael Mitrano, Treasurer

    A recent mailing to members who had not yet renewed has thus far prompted eleven renewals.  Our member count is now at 80.  In dollar terms, member dues for this fiscal year to date are within 2% of the amount at the same time a year ago.

    Recent expenses have been minimal and our surplus for the year to date is about $1,700.

    On a cumulative basis, the surplus is slightly over $24 thousand.

    Proposed Field Trip to Arizona Sky

    by Rex Parker

    Slide 1
    At the November meeting, I presented “Galaxies, Comets and Pixels from the High Desert”, a glimpse of an astronomy haven, the Mt Lemmon Sky Center.  Located an hour north of Tucson AZ, the site has excellent facilities for astronomy on the top of 9300-ft. high Mt Lemmon.  The highlights of my trip were observing visually and with CCD camera under the tutelage of renowned astrophotographer Adam Bloch.  Adam runs the University of Arizona programs on Mt Lemmon. He has the keys to a fantastic 32-inch RC telescope, which gave the best deep-sky views I’ve ever seen, under clear dark skies (sub 2-arcsec. seeing).

    Here’s a concept to consider:  a 2014 AAAP field trip to Tucson and Mt Lemmon.  On a long weekend or more, we could combine astrophotography and image processing techniques with visual observing, or do strictly visual observing depending on members’ interest.  The club would have to formally arranged the details to get access to the 32-inch RC Schulman telescope with Adam or an assistant in charge.  The costs would include airfare to Phoenix or Tucson, car rental, and lodging and meals at the University’s facilities on the mountain, plus a stay-over in the Tucson area.

    If you’re interested please let me know.  We can discuss at an upcoming meeting.  It would be great to have a AAAP field trip to Mt Lemmon.

    Minutes of the February 11, 2014 AAAP Meeting

    by Michael Wright, Secretary

    Director Jeff Bernardis opened the meeting.  He congratulated and awarded an observatory key to new keyholder Kevin Mooney and requested a volunteer to form the nominating committee for next year’s officers.

    Program Chair Kate Otto introduced Princeton Astrophysics post-doc Renee Hlozek who introduced the speaker for the evening, Prof. Craig Wheeler of the University of Texas at Austin.  Prof. Wheeler specializes in the astrophysics of violent events: supernovae, neutron stars, black holes, gamma-ray bursts and the relation of these events to astrobiology.

    Before beginning, Prof. Wheeler recognized member Insu Yi, who was a graduate student at U of T during Prof. Wheeler’s tenure as Department Chair.  Prof. Wheeler spoke about the current supernova in M82 and latest theories to explain type IA supernovae including historical supernovae records and new evidence from space-based telescopes like the Chandra X-ray Observatory.  Following the talk, the audience went outside to see the current supernova in M82 (the Cigar Galaxy) through John Giles 11-inch Dobsonian.  Unfortunately, the supernova and galaxy were lost in the background glow.

    Following 30 minutes of observing, Jeff convened the business meeting.  Rex Parker observed that about 95 people attended the lecture, which almost filled the lecture hall.

    Friends of AAAP Mail List – Secretary Michael Wright proposed creating a mailing list for non-members to receive notices of AAAP public events.  The idea was received favorably so he will create the list.

    StarQuest – Mike explained that he called a meeting to begin planning for StarQuest, which was poorly attended.  Currently, volunteers are limited Ludy D’Angelo, Jim Poinsett, Kate Otto and Mike.  He suggested that the lack of additional volunteers indicates that there is no interested in organizing a public star party and recommended that the event planned for Sept. 26-28, 2014 be an observing event for members and guests.  Rex suggested that the club promote StarQuest to new members and beginners as an opportunity to try out different scopes and learn more about observing.  Based on his experience working on StarQuest, Bill Murray indicated that attendance would drop dramatically after a year or two of bad weather ruining public star parties.  Gene Ramsey suggested having a picnic in the summer combined with a star party at the observatory.  Mike pointed out that an observing-only event is easier to cancel for bad weather.  Jeff suggested that we consider the options and make a final decision at the next meeting.

    Mount Lemon Trip – Rex proposed that the club organize a trip to the Mount Lemon Observatory near Tuscon, Arizona.  He envisioned six to twelve members staying on the mountain for three-days to use the telescope for observing or astrophotography.  His recent astrophotography workshop cost about $800 excluding travel expenses so he anticipated that the stay would less than that.  Accommodations in the dormitories and meals by the observatory’s cook would be included.  He volunteered to contact Andy Block so find out what could be arranged.  The idea was well received by those present.  The preference seemed to be for observing.  Rex suggested that additional days could be added if some members wanted to stay on to do astrophotography.  In response to Bill’s question, Rex thought that members could bring their own scopes.  Mike suggested that the club organize the stay, and members make their own travel arrangements to give them the most flexibility to visit other attractions in the area.  Mary Hayes asked about the best time weather-wise to visit.  Rex said he would research it, but thought the fall would probably be best.

    New Observatory Donation – Bill reported that he learned from UACNJ about an NJIT professor who may be interested in purchasing the dome for an observatory that he wants to build at Jenny Jump.  Bill volunteered to contact him.  Jeff reminded that the club cannot make any representations about the completeness or suitability of the dome because we have not seen it assembled.

    Nominating Committee – Jeff reiterated his call before the lecture for a volunteer to lead the nominating committee.  No one stepped up.

    Program Chair’s Report – Kate announced that a speaker has not been found for the March meeting, but member Bob Vanderbei will speak at the April 8 meeting and Neta Bahcall of Princeton Astrophysics will speak in May.

    Simpson Observatory – Gene reported that reported that the Park Administration has not cleared the roads to our observatory at Washington-Crossing Park so access is treacherous.  Dave and Jen Skitt have tried to keep the roof clear of snow and ice, but are losing the battle.  Also, locks are freezing up due to the cold.  The observatory is now closed for all use until further notice.  Lee Sandburg is training to be a keyholder.

    Website – Jeff said that Prof. Wheeler will forward his photographs of the supernova in M82 to the club.  Mike volunteered to coordinate with John Miller to post them on the web.

    Outreach Report – Jeff reported for Dave Letcher that there are no outreach events on the schedule.

    Jeff adjourned the meeting at 10:00 p.m.

    India’s Space Program

    by Prasad Ganti

    I am a proud Indian American and enthusiastic and proud of both American and Indian space programs.

    India launched a mission to Mars a few months back. The orbiter called “Mangalyaan” (Mars craft) is enroute to Mars now. A few years back, India sent an orbiter to the moon called “Chandrayaan” (Moon craft). The moon mission yielded a very high quality digital elevation map of the moon, and a global mapping of elemental abundance and mineral concentrations from spectroscopic studies. It even attracted international payloads from US and Europe in this remote sensing mission.

    The Indian space program has come a long way in the last 50 years or so since its humble beginnings. Much of it did not make headlines as the cold war era space race was on. Back then, space was the prerogative of only the superpowers and the advanced nations. It all started after India got independence from Britain in 1947.

    Dr. Vikram Sarabhai was the father of Indian space program. He was a very inspirational leader. The aim of the program was to achieve self-reliance in this critical technology and take the benefits to the common man, which was important because valuable resources were being expended by a developing country towards what was considered to be esoteric program akin to a rich nation’s adventure. India’s space program started in the early 1960s with the scientific objectives of exploring the earth’s atmosphere and ionosphere and studying astrophysical objects using rockets. Universities were involved right from the beginning of the program.

    The program started off with building and launching sounding rockets for probing the near-earth environment including the upper regions of the atmosphere. They can carry scientific payload, but cannot impart the velocity needed to orbit the payload. A launch vehicle’s final stage provides the necessary velocity to put a payload into orbit.

    Then the program moved to building of satellites and launching them on other countries’ launch vehicles. Satellites were used for communication and remote sensing. The first communication satellite was named “Aryabhata” and launched in 1975, named for an ancient Indian mathematician. Remote sensing was based on imaging. It is said, although never officially confirmed, that the images from these satellites were used to track Bin Laden to the Tora Bora mountains.

    Next in the evolutionary stage was the development of launch vehicles. SLV3 (Space Launch Vehicle 3) was the first one to launch lighter payloads. Then it moved to ASLV (Augmented Space Launch Vehicle) before settling on PSLV (Polar Space Launch Vehicle) as the workhorse for launching different payloads to near-earth orbits. SRE1 (Satellite Recovery Experiment) brought back an orbiting space capsule to the earth demonstrating re-entry capabilities. There were failures along the way, as is the case with any space program.

    Next in the series is the GSLV (Geostationary Space Launch Vehicles). There were early failures so it is still a work in progress. It is a three stage rocket with first stage powered by solid fuel, second by liquid fuel, and the third stage by a cryogenic engine. Fearing India might use cryogenic engines in its missile program, the US tried to discourage other nations like Russia from selling them to India. Politics apart, India has developed its own cryogenic engine. GSLV can place larger satellites and spacecrafts (up to 5000 lbs) into the Geosynchronous Transfer Orbit because of the higher thrust generated by the cryogenic engines,

    India’s rockets are launched from Sriharikota in South India. It is the equivalent of the Kennedy Space Center in Florida. Located on the east coast of Bay of Bengal, the space center is named for Satish Dhawan, an ex Chief of the Indian Space Research Organization (ISRO), the Indian equivalent of NASA. ISRO will construct a second vehicle assembly building at the second launch pad at Satish Dhawan Space Center this year, which would increase its launching capacity to 10-12 launches per year.

    India’s space program has been a good commercial venture so far. Launching satellites for other countries and selling data from its remote sensing satellites generates revenue. Given India’s low costs, the space business is a good money earner for the country. Of what use is India’s space program for the Indian masses? Last year, a fearsome cyclone struck the east coast of India (hundreds of miles north of Sriharikota). Timely information by the satellite-based early warning system helped in mass evacuations and prevented of thousands of deaths. A logistics exercise by an otherwise listless Indian bureaucracy came in for much praise.

    Why go to Moon and Mars? Madhavan Nair, an ex-Chief of ISRO commented “Twenty years from now when space travel is likely to become mundane like airline travel today; we don’t want to be buying travel tickets on other people’s space vehicles”!

    Incidentally, a crater on the dark side of the Moon is named for Dr. Sarabhai. Also, India was the first country with whom the US shared samples of moon rocks that Apollo 11 returned to Earth.

    Japan Launches Next Generation NASA/JAXA Meteorology Satellite

    by Dr. Ken Kremer, AAAP and Universe Today

    NASA GODDARD SPACE FLIGHT CENTER, MARYLAND –  A next generation US/Japanese weather observatory aimed at gathering 3D measurements of global rain and snowfall rates  thundered to orbit during a spectacular night time blastoff from the Tanegashima Space Center, Tanegashima Island, Japan.  The Global Precipitation Measurement (GPM) Core Observatory launched at 1:37 p.m. EST (3:37 a.m. JST Friday, Feb. 28) atop Japan’s H-IIA rocket.

    GPM will directly benefit society with improved weather forecasts and climate change research. Researchers will use the data to study freshwater resources, floods and droughts, hurricane formation and tracking. It will enable more advanced warnings of extreme weather conditions like superstorm Sandy and help identify and determine the effects of global climate change.

    “GPM will provide high resolution global measurements of rain and snow every three hours. It’s precipitation measurements will look like a CAT scan,” Dr. Dalia Kirschbaum, GPM research scientist, told me during a prelaunch interview in the cleanroom at NASA Goddard.  “The radar can scan through clouds to create a three dimensional view of a cloud’s structure and evolution.”

    The four-ton GPM is the lead observatory of a constellation of nine advanced weather research satellites contributed by the US, Japan, Europe and India.  It is the first satellite to measure light rainfall and snow in addition to heavy tropical rainfall.

    “GPM is the direct follow-up to the currently orbiting TRMM satellite,” GPM Project Manager Art Azarbarzin told me in a prelaunch interview in the cleanroom. “TRMM is reaching the end of its usable lifetime, and we hope GPM has some overlap with observations from TRMM.”

    For more about GPM read my articles here:

    Prof. Craig Wheeler Credit: J. C. Wheeler

    Serendipitously, Prof. Craig Wheeler of the University of Texas will be in Princeton on Tuesday, February 11 and has agreed to speak to AAAP about the current supernova in M82.  AAAP is jointly sponsoring this meeting with our friends in the Princeton Astrophysics Department.     As usual, the meeting with begin at 8:00 p.m. in Peyton Hall, 4 Ivy Lane, Princeton.  Gene Ramsey has graciously agreed to yield the podium and postpone his talk originally schedule for Tuesday to April 8.  If the weather cooperates, we hope to observe the supernova after the talk.

    J. Craig Wheeler is the Samuel T. and Fern Yanagisawa Regents Professor of Astronomy at the University of Texas at Austin, where he specializes in the astrophysics of violent events: supernovae, neutron stars, black holes, gamma-ray bursts and the relation of these events to astrobiology.  Prof. Wheeler has published about 200 papers in refereed journals and conference proceedings, has edited books on supernovae and accretion disks.  He published a popular astronomy book, “Cosmic Catastrophes: Supernovae, Gamma-Ray Bursts and Adventures in Hyperspace“.  Prof. Wheeler also wrote a novel, “The Krone Experiment“, and co-authored the screenplay, which was made into an independent film.

    From the Director

    by Jeff Bernardis, Director

    Stephen Hawking Credit: NASA

    Stephen Hawking Credit: NASA

    I’ve never been one to be into the cosmology aspects of our hobby, particularly in the areas dealing with general relativity.  Some of the concepts are really paradoxical to think about, although I can appreciate the way that great minds can conceive of them.  One of these great minds of our time is Stephen Hawking.  Despite his physical ailments, he is, in my mind, one of the most thought provoking people on the planet.  Just imagine what he could do if he had all of his faculties.

    Back in the late 90’s, Stephen Hawking published a book entitled “A Brief History of Time”.  I figured that here was a brilliant mind that I have ultimate respect for, who has reduced this elusive topic down to just over 200 pages.  I purchased the book with the anticipation that I was finally going to be able to wrap my hands around these concepts.  I’m not sure I ever finished the book.  I think I got just past a discussion on event horizons when my eyes glazed over; it just wasn’t sinking in.

    Through the years, I’ve gradually absorbed more knowledge about the subject, and while my level of knowledge is basic at best, at least I feel comfortable with it.

    So now Stephen Hawking has raised his voice again with a somewhat controversial hypothesis.  In late January, Hawking published an article in which he contends that event horizons may not be as rigid as everyone has theorized to this point.  His hypothesis is that event horizons, as we have defined them, do not exist, but there are “apparent horizons” that persist for a finite amount of time.  As the quantum particles within the horizon shift, the horizons themselves shift allowing energy and matter to escape.

    Who knows what is right?  This just a theory conceived to explain our observations.  It will be interesting to see how the cosmologists debate this question.

    We in the AAAP are blessed in that we have some of these theoreticians right here on the Princeton campus right in Peyton Hall.  We’ve heard from some of them in the past at our meetings, and I’m sure we’ll hear more from them in the future.  We might not ever know the final answers to these questions, but we are certainly in the right place to be an audience to the debate.
