I thought you Old Town Astronomer list members might be interested in
this class. Basics of Interplanetary Flight! If so read on!
Hello -
I'd like to invite you to consider joining us, starting next week, for
"Basics of Interplanetary Flight," a night course open to the public.
The first class meeting is Thursday September 13, 2007. This week,
though, is the week to register: late registration fees start Monday.
Classes are hosted by the Art Center College of Design Public Programs,
at their award-winning South Campus building (converted wind tunnel
facility) on Raymond at Glenarm in Pasadena.
This is hands-on interplanetary exploration. In the course of seven
consecutive Thursday evenings, we will experiment together to
intuitively learn the keys to interplanetary flight. We can usually
count on enjoying a stellar guest speaker, as well. So far, previous
class participants have included physicians, secretaries, film
producers, engineers, undergrads, grad students, writers, teachers,
pilots, architects, even a celebrity. Here's a quote from a participant
in the summer term that ended recently:
"Incredible. Interesting topics were explored in a fun way, often with
experiments. Each night left me eager to learn more."
We generally divide our three-hour meetings into developing three lines
of inquiry:
(1) Observing and grasping each of the major factors in the whole
environment in which we live and operate our robots: being the companion
of a dwarf star in a bubble orbiting a super-massive black hole at the
center of one of many galaxies (and understanding just how this is known);
(2) Learning how spacecraft are put together, what all their components
do, how they work, and why;
(3) Soaking in the results; seeing and experiencing new worlds,
encountering the latest and ongoing discoveries.
Information from the Art Center course catalog is included below.
Substantial tuition discounts are offered to teachers, members of The
Planetary Society, and others. For more details, and a link for
registration, see http://people.artcenter.edu/doody. If you have any
questions, please email me at doody(a)artcenter.edu
Thanks!
Dave Doody
E/078 Basics of Interplanetary Flight noncredit $395
Art Center at Night is pleased to offer you this extraordinary
opportunity to study the fundamentals of robotic space flight with
Caltech/JPL senior engineer Dave Doody, Flight Operations Lead for
the Saturn-orbiting Cassini spacecraft's realtime operations. We
have as our home a very rare planet, the companion of a
star-in-a-bubble, orbiting the distant black hole at our galactic
center. In this 7-week workshop, you will look back at our planet
from this greater perspective, and explore the vehicles, the
techniques, and the science experiments involved in today's ongoing
extraterrestrial exploration. Many familiar products such as cell
phones, medical devices, and imaging systems have developmental
roots on the edges of robotic space flight. Surveying these roots
may help designers conceive future products. Knowing how real
spacecraft move may be useful for filmmakers and illustrators. The
range of topics will intrigue any curious participant. Class
discussions will be enhanced by ongoing Q&A, many hands-on
demonstrations, design-based learning sessions, and a "guest star"
appearance or two. No prerequisites.
7 sessions Thursdays 7 -10 pm Dave Doody

Jane and I became familiar with the Pomona Valley Amateur Astronomers a
few months ago when she spoke to them on the Cassini mission. It's a
great club, and a great location, especially if you're more in the
direction of Pomona than Pasadena.
Tonight I'm going to give the talk that I gave last year in Ireland at
the Whirlpool Star Party in Birr. It's a brief travelogue of the
Sidewalk Astronomers' summer excursions to the great national parks of
the western U.S., along with the talk I've given at the parks on the
vanishing Milky Way, titled "You Are Here." I'll add some photos from
our visit to Bryce Canyon park this summer as well.
If you're interested in attending, the club web site is here,
<http://www.pvaa.us/> and directions to the 7:30 p.m. meeting are here
<http://www.pvaa.us/maps/meet.html>
Late tonight, or actually early tomorrow morning, scientists are
forecasting a rare return of the Aurigid meteor shower. Jane sent some
information about it in an earlier message.
While I'm giving my talk this evening, she will be at NASA Ames in
Northern California, installing equipment on a small Gulfstream business
jet, and preparing with a group of researchers to document the meteor
shower at an altitude of 50,000 feet. It should be quite a story.
I currently plan to observe the shower from home near Sawpit Wash in
Monrovia in a comfortable chair. :)
Best regards,
Mojo

Here is another reason to wake up early on Saturday morning - a rare
meteor shower! Bright shooting stars should be visible even with a
big old bright moon, and our city light pollution. Look to the East
and Northeast.
"Some time in the 40 years or so around 4 A.D., comet Kiess (C/1911
N1) passed by the Sun, ejecting a cloud of dust particles. The comet
returned in 1911, after completing one orbit. The dust particles were
pushed by the Sun's light into slightly wider orbits and have been
returning ever since, forming a thin ongoing stream of dust that
usually passes just outside Earth's orbit. On occasion, the combined
gravity of the solar system's planets moves this dust trail into
Earth's path. Earth encountered this 2000-year-old dust in 1935,
1986, and 1994, causing a meteor shower known as the Aurigids."
http://aurigids.seti.org/
Best viewing direction:
Best viewing: Keep Moon out of field of view (best to block behind
obstruction such as telephone pole, then watch whole sky), avoid city
haze that scatters moonlight
Best direction: East and Northeast
Best time: Start one hour before peak, then see the rate of meteors
increase and decrease while Earth travels through the shower
When:
Date: 2007 September 1
Peak time: about 11:33 +/- 20 minutes UT (= 04:33 a.m. Pacific
Daylight Savings Time).
Duration: about 1.5-hour
Width: 25 minutes above half the peak rate
What:
Peak rate: ZHR (Zenithal Hourly Rate) = 200 per hour (10-minute interval)
Meteor brightness: mostly -3 to +3 magnitude
Shower radiant: constellation Auriga (Radiant at RA = 92, Decl. = +39)
Entry speed: Vinf = 67 km/s
Where:
Visible from: California, Oregon, Hawaii, Alaska, Mexico [see flux
applet for visibility from your location]
Moon:
4 days past Full Moon, high in the sky
Important because:
Once in a lifetime crossing of the dust trail of a known long period
comet (comet Kiess).
Public interest:
When you make a wish, consider that each meteoroid was released at
some unknown moment during the period 36 B.C. - A.D. 45.

Here are the timings for tonight's total lunar eclipse.
A lunar eclipse happens when the moon passes directly behind the Earth
relative to the sun, and the moon passes through the Earth's shadow.
Mid eclipse is a 3:37 a.m. That's when the moon will be its darkest,
usually a deep red. Some light reaches the moon by refracting through
the Earth's atmosphere to give it that dull red glow.
Before the total eclipse begins, you'll see the shadow moving onto the
moon for about an hour. After it's over, again you'll see the shadow
moving off the moon.
I'm hoping to see all three parts of the eclipse. I love seeing the
moon partially in the Earth's shadow.
Here are the timings for each phase:
1:51 a.m. Partial eclipse beings
2:52 a.m. Total eclipse beings
4:22 a.m. Total eclipse ends
5:24 a.m. Partial eclipse ends
Set your clocks! No optical aid required. Just enjoy seeing the moon
go through those fascinating changes tonight.
Best regards,
Mojo

The weather forecast for tonight has been deteriorating steadily, with
lots of cloud cover expected. We'll have a "look see" at about 7:00 at
our street corner, but if it doesn't look promising, we'll indulge in
some alternative activities. :)
Cheers,

Hi all, the weather looks excellent for astronomy tonight in Pasadena.
Jane and I will set up in Old Town Pasadena on Colorado Blvd., somewhere
near Delacey. We look for a parking spot on the north side of the
street somewhere in the two-block stretch between Fair Oaks and Pasadena
Av. We'll plan to be there from about 7:30 'til 10.
We'll have a large gibbous moon tonight, and a good look at Jupiter.
Tonight at 7:55 the International Space Station will fly almost directly
overhead, visible from anywhere in L.A. county. Look for it like a
bright slowly moving star, beginning in the northwest, and passing to
the southeast. It'll be brighter than any other stars, and it won't
have blinking lights like an airplane. It takes about five minutes for
it to cross the sky.
Tomorrow (Saturday) we'll set up in Monrovia at the corner of Myrtle and
Lime, from about 7:30 'til 10, with a slightly bigger moon.
Later we'll update you on the total lunar eclipse visible early Tuesday
morning!
Best regards,
Mojo

From the newsletter for Weekend America, on public radio, it looks like
they'll be doing a rebroadcast of their story from May 19 that featured
Jane, Mojo, and John Dobson. The program airs locally on KPCC 89.3 on
Saturday from 1:00 p.m. 'til 3:00 p.m.
But you can hear the story as it aired on May 19 here:
<http://photo.whiteoaks.com/2007-05-19-weekend-america/sidewalkastro.mp3>
This weekend Jane, Mojo, and Gary and his family are off to do "Stars
over Yosemite" at Glacier Point in Yosemite National Park. Dave, Todd,
and Carolyn are planning to be in Monrovia at Myrtle and Lime Saturday
night. Drop by and say hello! We should have a great crescent moon,
and nice Jupiter this weekend. Maybe we'll have some visitors who hear
the Weekend America story. :)
We'll be doing more sidewalk astronomy next weekend with a big gibbous
moon. And Jane or I will update you on the total lunar eclipse visible
from here in the early morning sky on Tuesday morning, August 28.
Clear skies,
Mojo

Hello to all our OTAstro list!
My August What's Up is Up on the JPL and NASA websites. It's about
the Perseid Meteor Shower mostly, and is aimed at the general public
- with some good easy to understand graphics aimed at the general
public.
Here is the place where they are archived permanently (this is the
link to bookmark), on the JPL Education page
http://education.jpl.nasa.gov/amateurastronomy/index.html This link
includes video formats that are useful for astronomy clubs,
classrooms, museums and planetariums, plus this month I added links
to some lunar and meteor educational material - these are aimed at
grades 4-12.
The best time to view the Perseids will be Monday morning before
dawn, but that's not really convenient for most people. Saturday
night/Sunday Morning will yield many meteors especially after 2 a.m.
, with horizon skimming meteors at midnight, before Perseus rises
very high above the horizon. If you go someplace dark, you'll see
more than you will in the LA Basin, and if you can't get away, just
put some space between you and the light sources - a side of a house
or trees can help some. You will see them everywhere, but if you
mentally trace the shooting stars to their "source" you'll be looking
in the direction of Perseus, in the NE Sky.
Local dark sky spots will be up I-5 at the Templin Highway turnoff,
Mt. Pinos - on Frazier Peak, and up towards Mt. Wilson - but there is
still a lot of LA glow up here. The Desert East of us affords darker
and drier skies.
The Andromeda Society of Yucca Valley hosts a monthly star party at
Joshua Tree National Park's Hidden Valley picnic area Saturday Aug 11
- http://www.andromedasociety.org/
The Pomona Valley Amateur Astronomers will be at JTNP's cottonwood
Springs campground Aug 11. Later on in August, Mojo speaks to the
club's general meeting at Harvey Mudd College on the 31st.
http://www.pvaa.us/calendarpage.asp
The Peninsula Astronomy club of Northern California will be up at
Glacier Point at Yosemite this weekend - if you could possibly get
up there, it's magical for meteors. Mojo and I will be there the
following weekend with one of our Northern California Astronomy clubs
- the San Jose Astronomical Association. Most weekends, some club is
hosting free star parties for the public at Glacier Point.
http://www.aanc-astronomy.org/yosemite.html
If you observe the Perseids and would like to contribute your
observations, here's an ongoing meteor observing program you might be
interested in: http://aurigids.seti.org/ . I'll be participating in
this airborne mission observing the Perseids and Aurigids with the
same group Mojo and I have worked with for almost 10 years counting
the exciting meteor showers.
Oh, and since we'll be at Yosemite on our usual sidewalk astronomy
weekend of the 17th 18th August, check the OTAstro website
http://www.otastro.org/ for dates and details. I think our usual
group will be in Monrovia without us on Saturday the 18th, but
probably not in Pasadena on the 17th.
Jane and Mojo

Last December Dr. Chris Lintott, co-host of Sir Patrick Moore's"The
Sky at Night" TV show joined the sidewalk astronomers in Monrovia.
With Chris, were series producer Jane Fletcher, and the camera and
sound crews. I brought out my homemade 10-inch f/7.3 Dobsonian
telescope, Stardust, and a couple of other homemade scopes for the
evening. Our segment (with John Dobson), is on this month's show,
which you can see here:
http://www.bbc.co.uk/science/space/spaceguide/skyatnight/proginfo.shtml
Click on July's episode - a Sting in the Tail - the show starts out
with information about the constellation Scorpius.
Here is our photo album of the evening:

In other TV news, on the US History channel is a show called "The
Universe"
http://www.history.com/minisite.do?content_type=mini_home&mini_id=54036.
Each show (there is one about Cassini) runs several times so check
your local listings. The DVD can be ordered from this website too.
I've watched a couple of them, both Jupiter and the moon feature some
Cassini colleagues, and they're great!

The weather looks lovely for sidewalk astronomy tonight and tomorrow.
The weekend features a lovely first-quarter moon and Jupiter.
Tonight we'll be looking for space near the Barnes & Noble on Colorado
Blvd., between Delacey and Pasadena Ave. It's Harry Potter release
night, we like to try to expand on some of the astronomical themes from
the books for all the young wizards and muggles.
Tomorrow night we'll be at our usual corner in Monrovia, at Library
Park, Myrtle & Lime.
Drop by and say hello!
Jane's great monthly video "What's Up" is still available from the JPL
web site. We're both delighted that it's been featured for the past
week on the main NASA home page as well, at <http://www.nasa.gov/>.
If you use iTunes, you can subscribe to the free NASA podcasts from JPL,
and have her two-minute monthly video downloaded automatically. It's
fun watching it on my iPod. :)
