SB SAT @ AMSAT $ANS-156.01 Eclipses Continue to Affect AO-51 Operation
AMSAT News Service Bulletin 156.01
From AMSAT HQ SILVER SPRING, MD.
June 5, 2011 To All RADIO AMATEURS BID: $ANS-156.01
Last week's ANS bulletins reported that the AO-51 Command Team had successfully restored the satellite to partial operations. AO-51 at that time required a reload/reboot sequence every time it emerged from eclipse due to the Integrated Housekeeping (IHU) computer crash- ing from low battery voltage.
This week AMSAT VP-Operations, Drew Glasbrenner, KO4MA said, "AO-51's computer has been running for over 5 hours now. We have left the sat- ellite in repeater mode 145.88/435.15 for the time being, at over 2 watts. We are very surprised by this development to say the least. Without Whole Orbit Data we are flying a bit blind, so would really like to know what the satellite is doing in eclipse. Please send your reports to me or to the amsat-bb. Southern hemisphere observations are most very welcome."
+ Robert, NH7WN reported from Honolulu: "AO51 was alive and well as she came out of eclipse on June 2. I was able to hear myself per- fectly on the downlink (145.880 up and 435.150 down)."
+ Brett reported: "Heard on AO-51 today pass over Australia/New Zealand 145.880/435.150 Strong signals. Copied VK1AMG, ZL2BX, VK4VDX."
+ Alan, ZL2BX reported: "AO-51 solid signals in ZL. AOS (0459 UT) about five minutes after it came out of eclipse. Later on June 3, I can finally confirm that AO-51 is loud and clear over ZL in full eclipse. with solid signals from the transponder."
+ Dave, KB5WIA reported from California, "AO-51 was in great shape as it passed south above the Pacific Ocean on June 3. I had a nice S9+ full quieting downlink for the entire pass."
The Command Team has analyzed AO-51 live telemetry when the satellite is in range of a ground station because Whole Orbit Data is lost when the IHU Computer crashes. Drew, KO4MA summarized, "Cell 3 is reporting 0.0 volts, so it's clear it has shorted completely."
Donations for Fox and ARISSat-1 are being collected. If you haven't yet donated, please drop by http://www.amsat.org, or call Martha at the AMSAT Office at 1-888-322-6728 today and help us get Fox in space.

SB SAT @ AMSAT $ANS-156.05 AMSAT-DL Break FUNcube Dongle Distance Record
AMSAT News Service Bulletin 156.05
From AMSAT HQ SILVER SPRING, MD.
June 5, 2011 To All RADIO AMATEURS BID: $ANS-156.05
A story first reported on the Southgate ARC news web site reported members of AMSAT-DL have received the Stereo B spacecraft at a dis- tance of 219 million kilometers using an AMSAT-UK FUNcube Dongle Software Defined Radio as the I.F. in combination with a downcon- verter.
Stereo B transmits in the X band around 8 GHz so could not be receiv- ed by the FUNcube Dongle directly since that covers 64-1700 MHz. A downconverter was installed at the dish feed and the 1280 MHz output was fed into the FUNcube Dongle SDR.
The frequency of Stereo B varies due to Doppler shift (of the rotating Earth) and was calculated by the tracking software.

+ Check your ISS Keps! According to Roscosmos, the ISS boosted its orbit by 3.74 km Friday. This will result in a "slippage" of predicted times of approximately 70 seconds per day until the Keps catch up. The AMSAT NASA.ALL Keps will probably not reflect this until next week, so be certain to update from Celstrak or Space Track.

SB SAT @ AMSAT $ANS-156.07 2011 AMSAT Field Day Competition
AMSAT News Service Bulletin 156.07
From AMSAT HQ SILVER SPRING, MD.
June 5, 2011 To All RADIO AMATEURS BID: $ANS-156.07
AMSAT Director of Awards, Bruce Paige, KK5DO says, "It's that time of year again: Summer and Field Day!"
Each year the American Radio Relay League (ARRL) sponsors Field Day as an emergency preparedness exercise. The event takes place during a 24-hour period on the fourth weekend of June. For 2011 the event takes place during a 27-hour period from 1800 UTC on Saturday June 25, 2011 through 2100 UTC on Sunday June 26, 2011. Those who set up prior to 1800 UTC on June 25 can operate only 24 hours.
The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event.
Bruce advises, "If you are considering ONLY the FM voice satellites like AMRAD-OSCAR-27, SaudiSat-Oscar-50, or AMSAT-OSCAR-51 for your AMSAT Field Day focus. Don't, unless you are simply hoping to make one contact for the ARRL rules bonus points."
The congestion on FM LEO satellites was so intense in prior years that we must continue to limit their use to one-QSO-per-FM-satel- lite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice. You will also be allowed one digital QSO with the ISS or any other digital, non- store-and-forward, packet satellite (if operational).

SB SAT @ AMSAT $ANS-156.09 US Army Supports Student Launch Program
AMSAT News Service Bulletin 156.09
From AMSAT HQ SILVER SPRING, MD.

White Sands Missile Range NM (SPX) Jun 03, 2011. A scientific rocket screamed skyward at Spaceport America May 20, 2011, as students from all over New Mexico, as well as Texas and Arizona came to see their scientific payloads fly into space during a scientific and educational mission supported by White Sands Missile Range.
The rocket carried 27 experiments from elementary, middle schools, high schools and universities into space before returning to earth, and landing at White Sands Missile Range, or WSMR. Under the New Mexico Space Grant Student Launch Program, students were able to assemble their own scientific payloads to be launched over 65 miles above the earth.
The student payloads, divided into seven different canisters within the rocket were a varied as the students who built them. Crammed into the canisters were cameras, radiation monitoring sensors, and other measurement devices, along with some more advanced systems.
"We had things from roasting green chilies to marshmallows to using a piezo electric board, tesla coils, and a lot of temperature monitors and Geiger counters, a bunch of variety, and a lot of magnetic experi- ments also," said Bruce Lewis with the space grant office and spaceport office.
The rocket launch represented more than just an educational opportun- ity for the students, but a cooperative effort between different organizations and companies. Even though the rockets flight began at Spaceport America, a state-run spaceport, it ended its flight on White Sands Missile Range and used range airspace.
"This is White Sands airspace that we're flying in, so White Sand controls that airspace for us. We have a great relationship with White Sands and we had a lot of support from (WSMRs) team," said Pat Hynes, director of the Space Grant Consortium.
The recovery of the rocket, and it's return to the students was con- ducted by White Sands Missile Range's Army Air. While the rocket was awaiting recovery White Sands Missile Range Chief of Staff Dan Hicks spoke with the students about the future of high technology careers and the kind of opportunities in those fields offered by WSMR and the Army.
"The majority of the workforce consists of engineers and mathematicians and other scientific fields. We've got about 4,000 people on the test center and garrison side that have that type of background. So in order to be specific to what it takes to get a job out at White Sands one of the key things would be to continue your education into college and get a degree," Hicks said.
Hick Also answered questions from the students about spaceflight, how the range operates and the kind of radar systems used to track rockets like the one used in the experiment.
Data collected by these various devices had a variety of applications, with some being educational in nature, giving the students a glimpse of what it means to send something into space, and other experiments having more direct applications to the future of space flight.
"Some of it is great data; some of it is fun data. So you're got both the fun stuff and some things that are collecting real empirical data that NASA may be able to use in the future," Lewis said.
One experiment bridged the gap between the two. An experiment conducted by Aztec High School harvested the physical motion of the rocket in flight and converted it into electricity which was then used to power a small electric oven and roast a green chili. While roasting green chilies isn't critical to the future of space flight, the electricity could have other purposes.
"What we wanted to see is if you could power something in the rocket just using piezo electrics, just using the own forces of the rocket to generate it's own electricity while flying up into space," said Braden Goimarac, from Aztec High School's "Black Ops" science team.
