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.

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. Tom K8TL

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.

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@gmail.com or manually enter received data points at http://www.projectbluehorizon.com/ More information is available on their web page.
