FUTUTROS PROYECTOS PARA LA ISS
Hay varios proyectos por desarrollar en la ISS los cuales son:
Repetidora de FM, "Digi-Talker", Lanzamiento a mano de pequenos satelites
(como el sputnik RS-18 lanzado desde el MIR) y TV digital comprimida. Estos
planes se implementaran entre dos y cinco anios.
ANTENAS EN EL ISS
Es en el modulo FGB donde se encuentra instalada la antena sintonizada
solamente para dos metros la cual alimenta al radio de packet/fonia, el
cual transmite unicamente con 1.5watts erp, ya que las senales recibidas son muy
fuertes y cualquiera en tierra con una antena de ganancia 0dbd puede trabajar a la
estacion sin mucho problema.-

Susan is a beginner at working "pile-up" on the ham band, Please be
kind.
She is try to use the new ham jargon, CQ and QRZ.
And she is getting good at it.
So, here are a few tips to follow:
1. Wait for her to say CQ or QRZ before calling.
2. If she is talking so someone else, please wait for her to say CQ/QRZ.
3. When you call her speak slowly and say your call with each
transmission followed by OVER.
Good Luck and remember, she is still learning, lets make it easy for
her.

and Susan Helms
Mount Everest:
When I told my wife I was going to Mount Everest to play ham radio, she
thought I was joking. Then when documents arrived at the house from the
http://www.summiteverest.com/
Mountain climbing expedition, she began to worry. I was invited to go
to Mount Everest to be the base camp communications engineer,
responsible for daily image and data transmission from the 18,000 ft
base camp back to the states. Of course I was going to bring plenty of
ham gear too, including the MAREX SpaceCam1 project. I figured, if it
would work on Everest at 18,000 feet, it should work on ISS at 250
Miles. At one point I needed 2 Yacks to carry the ham gear and 1 Yack
for my stuff. I was planing on sending 50-100 SSTV images per day from
Everest to the south pacific on 80 meters daily. Then have several
stations in India and Australia relay the images around the world for
all to see. Unfortunately due to the poor economy in the states , the
funding dried up. One of my sponsors had to back out. Oh We'll, the
good news is my wife is happy, and I am sleeping in a warm bed, rather
than a cot at -30 below.
The Mountain climb is still continuing and you can see the travels of
Mike Johnston on the web page. Mike will make his summit attempt
between May 1 - 20.
Good luck Mike.

ARISS Enthusiasts:
I am pleased to inform you that the ARISS-US team delivered a new packet
module to NASA this week. This new packet module is expected to correct
several of the problems that have been observed on the current ARISS packet
system. This packet module is expected to go through a "bench review"
(or
inspection) by one of the US astronauts next week. It is to be flown
on
ISS mission 7A.1 (STS-105) which is currently planned for launch in early
August.
Expedition 3 astronaut Frank Culbertson, KD5OPQ, is planning to make the
packet module changeout early in his ISS tour of duty. The current packet
module will stay on ISS where it will serve as a power supply for the
70 cm
station that will be installed in the Service Module later this year.
Some of the new features of this ARISS packet module includes:
1) All pertinent parameters are embedded in the PROM, so the packet module
should be fully functional even with a dead battery
2) The new Russian callsign RS0ISS is installed in the module. The
Personal Mailbox System (PMS) uses the callsign RS0ISS-1
3) A 1 meg memory for adequate PMS data storage
4) 8 bit capability to support Russian Cyrillic typesets
5) A one minute timeout disconnect from the PMS is no pertinent packets
are
heard
I would like to thank the following individuals from ARISS-US who worked
hard to make get this module ready for flight on the STS-105 mission:
Dan Schultz, N8FGV
Lou McFadin, W5DID
Gil Carman, WA5NOM

SUSAN HELMS, KC7NHZ, THRILLS FIELD DAY OPS FROM ISS
Astronaut Susan Helms, KC7NHZ, took time out aboard the International
Space
Station to join in the ARRL Field Day fray last weekend. The operation
was
believed to mark the first time anyone participated in Field Day from
space.
Helms worked several dozen stations--most of them Field Day operations--as
the ISS passed over the US. ARRL Contest Branch Manager Dan Henderson,
N1ND,
says the NA1SS contacts will count for Field Day credit, but they will
not
count for satellite bonus points.
Helms sounded like a veteran contester during Field Day, although not
without some confusion as to what exchange she should transmit. Initially
acting on incorrect information, Helms was giving out "one alpha maritime
mobile-Russia" for a Field Day report. Later, she resorted to "1 alpha
battery on the space station."
The NA1SS Field Day operation infused a lot of enthusiasm into the occasion.
"This Field Day is the one I'll remember the most, even after doing FD
for
40 years," said ARRL Wisconsin Public Information Coordinator Jim
Romelfanger, K9ZZ. Romelfanger worked NA1SS as part of the WB9FDZ Yellow
Thunder Amateur Radio Club Field Day crew. "Susan was having a ball up
there!" he said.
Dave Swartz, KC7RRH, said his club's Field Day operation was another lucky
enough to snag a contact with NA1SS. It happened almost by accident. Swartz,
who operated with the Federal Way Amateur Radio Club's WA7FW setup in
Washington, said the group was set up for a packet contact via the ISS
when
he heard Helms' voice coming over the speaker. Although he was on 20 meters
at the time, he grabbed the mike at the packet setup next to him and made
the QSO. Swartz said he was "very psyched" about working Helms but
disappointed not to get the bonus points.
Henderson said that ISS contacts will not count for bonus points because
the
ISS is not an "Amateur Radio satellite," as rule 7.3.7 specifies
<http://www.arrl.org/contests/announcements/rules-fd.html>;. Henderson
said
that, because of their nature, bonus points "need to be readily available
to
everybody," and the ISS offers only a limited window of opportunity.
As for the correct Field Day operating class for NA1SS, Henderson said
there
is more than one possible choice, but the question is largely academic.
"Whatever exchange she sent out, count it as a valid contact for Field
Day
and enjoy the experience," he said. Field Day entries require a list of
call
signs worked by band and mode.
Henderson said Helms' ISS Field Day entry will end up "in a class by
itself."

stations QSL to Radio Amateurs of Canada, 720 Belfast Rd--Suite 217, Ottawa,

==>NEW PACKET TNC ON THE WAY TO ISS
Amateur Radio on the International Space Station Board Chairman Frank
Bauer,
KA3HDO, says the ARISS-US team has delivered a new packet module to NASA.
"This new packet module is expected to correct several of the problems
that
have been observed on the current ARISS packet system," he said.
The module is expected to undergo a "bench review"--or inspection--in
the
near future by one of the US astronauts. It is scheduled to fly to the
ISS
on shuttle mission STS-105, currently planned for launch in early August.
Bauer says Expedition 3 Crew Commander Frank Culbertson, KD5OPQ, plans
to
make the packet module changeout early in his ISS tour of duty. Culbertson
will be joined aboard the ISS in mid-August by Russian cosmonauts Mikhail
Turin and Vladimir Dezhurov.
Bauer says all pertinent TNC parameters are embedded in the PROM, so the
packet module should be fully functional even with a dead battery. It's
believed the current TNC lost its backup battery. As a result it displays
<NOCALL> as a call sign. Stations cannot connect but have been able to
digipeat through the system, however. The new TNC will display the Russian
call sign RS0ISS. The Personal Mailbox System (PMS) uses the call sign
RS0ISS-1.

==>W1AW SEEKS 80-METER SIGNAL REPORTS
Maxim Memorial Station W1AW has changed its 80-meter bulletin antenna
system
and requests signal reports from those monitoring the 80-meter
transmissions. An 80-meter "cage" dipole joined the W1AW antenna farm
When is the ISS crew allowed to Operate Amateur Radio Voice:
The ISS crew is allowed to use the Amateur radio station for random
contacts only during their OFF hours. However the ISS crew has very
little amount of free time. As one ESA official said to an ARISS
meeting, "There is no such think as free time for ISS crew, all of there
time is accounted for". The best chance for a random contact with ISS
is during the weekends and after dinner time on the space station.
An interesting side note from the Mir days, is that when all hardware
on
Mir was working 100%, the Mir crew was too busy to talk on the Radio.
When Mir had power problems or things like a broken
refrigerator/freezer, the Mir crew had more time to experiment with the
Amateur Radio projects. No freezer, no blood tests, etc. So the crews
had more free time. I have seen a similar scenario on ISS. So look for
times when many projects are not working and that ISS crew is waiting
for new software etc from NASA and you may see a pattern of higher
activity.
-INFORME ISS:
A pocos d�as del lanzamiento de la misi�n STS-104, los
tripulantes de la ISS se esfuerzan en practicar con el brazo rob�tico
Canadarm-2, de manera que puedan realizar satisfactoriamente todas las
maniobras que se requerir�n para la instalaci�n del m�dulo esclusa, el
cual viajar� en el interior del Atlantis (ver imagen).
La NASA ha confirmado que el transbordador partir� el 12 de julio
a las 08:58:57 UTC, aunque la ventana se prolonga hasta las 09:08:56 UTC.
De hecho, la hora preferida es las 09:04 UTC, pero todo depende de la
posici�n exacta de la estaci�n espacial en el momento del despegue.
A bordo el Atlantis viajar�n el comandante Steve Lindsey, el piloto
Charlie Hobaugh y los especialistas de misi�n Mike Gernhardt, Janet Kavandi
y Jim Reilly. Dos de ellos realizar�n los tres paseos espaciales previstos.
Si todo sale bien, el Atlantis llegar� a la ISS durante la noche del
13 al 14, uni�ndose a ella con la carga en el interior de su bodega abierta.
El m�dulo llamado Joint Airlock ser� acoplado al Unity y servir� como
habit�culo para facilitar las salidas al espacio, tanto mediante trajes
rusos Orlan como con sus equivalentes norteamericanos. El JA pesa unas
seis toneladas y media y ha sido construido por Boeing bajo la supervisi�n
del Marshall Space Flight Center. Su punto de anclaje es tal que s�lo
puede ser unido a la estaci�n mediante el Canadarm-2. Su hermano peque�o,
el Canadarm-1 original, no tiene el alcance suficiente. Los paseos espaciales
de Gernhardt y Reilly servir�n para completar la uni�n del m�dulo esclusa
al Unity. Completada su misi�n, el Atlantis regresar� a la Tierra el 23
de julio.
Los t�cnicos consideran que los problemas que afectaban a las pruebas
del Canadarm-2 han sido resueltos. El brazo rob�tico ha funcionado sin
problemas durante las �ltimas semanas y por tanto est� listo para desempe�ar
su labor. Si se reproduce el fallo de comunicaciones en uno de los sistemas
electr�nicos de reserva situados en una articulaci�n, los programas, recientemente
actualizados, simplemente lo ignorar�n. Seg�n los estudios realizados
por los expertos, la articulaci�n no tiene ning�n problema. Es un chip
el que muestra un comportamiento err�tico de forma intermitente.
Los astronautas de la ISS, adem�s de trabajar con el brazo, est�n
dedicando varias horas a la semana para la realizaci�n y control de experimentos.
Precisamente, la NASA ha anunciado la recepci�n de las primeras lecturas
obtenidas por los detectores de radiaci�n instalados a bordo. Estos detectores
ayudar�n a los m�dicos a prever las posibles consecuencias biom�dicas
que puede tener la exposici�n de los astronautas, de forma continuada,
a un medio de radiaci�n espacial como el de la ISS. El sistema de dos�metros
pasivos (PDS) est� compuesto por una docena de detectores situados en
varios lugares del interior de la estaci�n. Los cient�ficos tratar�n ahora
de interpretar las lecturas obtenidas por la red, lo que desembocar�,
si es el caso, en varias recomendaciones.
En la Tierra, est� previsto que hoy 2 de julio se lleve a cabo el
traslado del transbordador Discovery (STS-105) hasta la rampa 39A. Su
lanzamiento est� previsto para no antes del 5 de agosto. Durante su misi�n,
el veh�culo transportar� suministros para la estaci�n, as� como tambi�n
a la expedici�n de larga duraci�n n�mero 3, que reemplazar� a la actualmente
en �rbita.
En octubre, Rusia deber� enviar una nueva c�psula Soyuz-TM de reemplazo.
La tripulaci�n de esta misi�n consiste en dos cosmonautas rusos y una
espacionauta francesa. Sin embargo, existe la posibilidad de que el ingeniero
de vuelo ruso sea sustituido por otro pasajero de pago. Como no hay tiempo
para entrenar a un turista, el candidato podr�a ser un astronauta extranjero
ya preparado. Se ha hablado, por ejemplo, de un canadiense. Si ello se
produjese, la francesa se encargar�a de las labores del ingeniero de vuelo,
tarea para la cual ya ha sido entrenada.
Y si Rusia busca dinero de todas las maneras posibles para hacer frente
a sus compromisos en la ISS, la NASA podr�a tener que afrontar un nuevo
y doloroso aumento de la factura. A los ya conocidos 4.000 millones de
d�lares de sobrecoste, se a�adir�an ahora otros 800 millones, con 300
a 600 millones m�s pendientes de confirmaci�n.
Pero lo peor podr�a estar a�n por llegar. Para luchar contra estos
sobrecostes, que la administraci�n Bush ha ordenado deben ser absorbidos
por el propio programa, la NASA se ha visto obligada a reducir los presupuestos
para investigaci�n cient�fica, as� como a eliminar el desarrollo del m�dulo
habitaci�n, el m�dulo de propulsi�n americano y el veh�culo de rescate
CRV. El problema es que sin este �ltimo, la tripulaci�n de la ISS deber�
permanecer en sus actuales tres ocupantes, lo que podr�a propiciar que
algunos de los pa�ses que participan en la iniciativa deseen retirarse
ante la falta de oportunidades de acceder al complejo. Si ello se produjera,
la NASA deber�a afrontar otros pagos adicionales en concepto de costes
de mantenimiento (quiz� hasta 1.300 millones de d�lares).
Las razones del sobrecoste son variadas, pero incluyen haber subestimado
algunas partidas o la adici�n de nuevos requerimientos. No parece que
los pa�ses de la ESA vayan a aceptar contribuir con m�s dinero en la ISS,
antes al contrario, y s�lo Italia podr�a aumentar su participaci�n ya
que sus empresas est�n encontrando nuevas oportunidades de negocio.
