RELEASE: 12-093
NASA'S GRAIL MOONKAM RETURNS FIRST STUDENT-SELECTED LUNAR IMAGES
WASHINGTON -- One of two NASA spacecraft orbiting the moon has beamed
back the first student-requested pictures of the lunar surface from
its onboard camera. Fourth grade students from the Emily Dickinson
Elementary School in Bozeman, Mont., received the honor of making the
first image selections by winning a nationwide competition to rename
the two spacecraft.
The image was taken by the MoonKam, or Moon Knowledge Acquired by
Middle school students. Previously named Gravity Recovery And
Interior Laboratory (GRAIL) A and B, the twin spacecraft are now
called Ebb and Flow. Both washing-machine-sized orbiters carry a
small MoonKAM camera. Over 60 student-requested images were taken
aboard the Ebb spacecraft from March 15-17 and downlinked to Earth on
March 20.
"MoonKAM is based on the premise that if your average picture is worth
a thousand words, then a picture from lunar orbit may be worth a
classroom full of engineering and science degrees," said Maria Zuber,
GRAIL mission principal investigator from the Massachusetts Institute
of Technology in Cambridge, Mass. "Through MoonKAM, we have an
opportunity to reach out to the next generation of scientists and
engineers. It is great to see things off to such a positive start."
GRAIL is NASA's first planetary mission to carry instruments fully
dedicated to education and public outreach. Students will select
target areas on the lunar surface and request images to study from
the GRAIL MoonKAM Mission Operations Center in San Diego.
The MoonKAM program is led by Sally Ride, America's first woman in
space, and her team at Sally Ride Science in collaboration with
undergraduate students at the University of California in San Diego.
More than 2,700 schools spanning 52 countries are using the MoonKAM
cameras.
"What might seem like just a cool activity for these kids may very
well have a profound impact on their futures," Ride said. "The
students really are excited about MoonKAM, and that translates into
an excitement about science and engineering."
Launched in September 2011, Ebb and Flow will answer longstanding
questions about the moon and give scientists a better understanding
of how Earth and other rocky planets in the solar system formed.
NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the
GRAIL mission for NASA's Science Mission Directorate in Washington.
GRAIL is part of the Discovery Program managed at NASA's Marshall
Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems
in Denver built the spacecraft.

Message-ID: <333765.40076.qm@xxxxxxx.xxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
Erich DK1TB has again implemented another great feature
into SatPC32 V12.8b by means of a "patch" file. You can
find it in the "downloads" link on his website, www.dk1tb.de
Scroll down to Section 7, Patches.
I often hear others talk about meeting someone, usually a
long distance new grid square, on a certain frequency. Since
doppler is always in play, telling someone you will be on
435.845 is meaningless unless you are both in the approximate
same location. If the other station is at LOS and you are at
AOS, your dial readings could be 15Khz apart. It's a great
way to miss a 60 second window.
The trick here is to use the same point of reference. That reference
would be the frequency you are on at the satellite receiver. The whole
idea of doppler correction is to be at a constant frequency within the
satellite receiver passband. To do that you have to adjust your uplink
frequency constantly. And you have to adjust your downlink frequency to
continue to hear yourself or someone else using full doppler correction.
Erich has now added the option of seeing the frequency you are on at
the satellite receiver. This is a common frame of reference so if you
tell someone you'll be on 435.845 at the satellite, they can be on that
same frequency even though your terrestrial dial frequencies will be much
different. Just adjust your receiver or use the up/down buttons in SatPC32
to set your frequency shown in the "Sat" window. That frequency will remain
constant as your uplink and downlink are controlled by SatPC32.
If you haven't managed to interface your radio with SatPC32, this is just
another reason to do so. Staying at a constant frequency at the satellite
allows many stations to share the bird without drifting into each other.
And being able to know exactly where you are in the passband without doing
the calculation in your head gives you more time to concentrate on making
a successful QSO! Rumor has it that even a certain Maritime Mobile
will soon be
controlling his radio with SatPC32.

Hi Erich, DK1TB
Congratulations for your new implementation into
SatPC32 V12.8b
It is really a great job seeing the frequency we are
on at the satellite receiver !

Shopping for new rig:
Does the 9100 do Classic mode "A" 2m up 10 M down? Received two answers
from ICOM Yes and No! It seems to me that it will but I want to be sure.
The recent review in QST said that the BA1 didn't support Satellite
operation, is that true?
Any one try it on EME?
Thanks in advance.

Hi Tom,
Yep, the 9100 does classic a mode with SatPC32.

John,
Thanks for mentioning this. I had missed his update. This makes SATPC32
unique in providing this support.
There is an article in the July/August 2010 issue of the AMSAT Journal
called "Bringing the One True Rule of Doppler Tuning into the 21st Century."
It explains in some detail the rational for doing this. If someone wishes a
copy, please contact me OFF LIST and I will send you a PDF.
73s,

Hello Everyone,
Here is one news item which is more timely at the moment rather than waiting
for the weekend ANS news cycle. (We'll post a reminder in the ANS).
Interested stations on the USA East Coast may wish to follow this flight on
VHF. The HF beacon may likely be heard with wider coverage:
+ The Project Blue Horizon 6 high-altitude transatlantic balloon
flight is planned to launch on Friday, March 23 at 2300 EST (UTC-4)
from Owego, NY transmitting on 7.1023 and 10.1466 MHz CW with the
N2XE call sign and 144.390 MHz FM APRS using the KD2AUD call sign.
Please send reports via e-mail to pbh18.data@xxxxx.xxx or manually
enter received data points at http://www.projectbluehorizon.com/
More information is available on their web page.
