Rapport från en astronaut

Det är intressant att läsa hur astronauterna upplever alla dessa skolkontakter som pågår hela tiden. Vackra ord….

ISS
Abstract from ESA Astronaut Samantha Cristoforetti’s logbook

Yesterday, December 15, I had my first HAM radio contact with school pupils.
A big hello to the students of the schools “Elena di Savoia” in Bari and
“Alessandro Volta” in Bitonto!  It was fun talking to you and thanks for the
great questions!

Amateur radio contacts between astronauts and school kids have a long
tradition on ISS, thanks to a little army of volunteers in many countries
who work with the local schools not only on the day of contact, but also in
the weeks and months leading up to the event: they teach students about
radio technology and about space, to get them ready and hopefully excited
about the event.

From my side, I only needed to be ready on the proper channel at the proper
time: it is very important, because we need direct line-of-sight with the
amateur radio station on the ground and the pass is only about ten minutes
long. A couple of minutes before the expected acquisition-of-signal time, I
started making calls to check if someone was already picking me up.
Eventually I picked up a call from the ground station and sure enough, we
started our conversation. I heard them loud and clear, which positively
surprised me: somehow I expected signal quality not to be as good. I hope
they had the same quality on the other side.

On such contacts, there’s no time for small talk and formalities: in less
than ten minutes, we had to make sure that the 20 students who were lined up
to ask their question got their chance. So here I was, ready to go. And here
came the first question – are you ready? Here’s it is:
“ It is known that people become taller when they are in space. What happens
to bio-molecules? Is there any alteration in the tertiary structure of
proteins?”

I almost fell off my chair… well, if I had had a chair. (Wonder what a good
equivalent of this expression would be in weightlessness… any suggestions?)

Where are the good old question about space food and the space toilet? Jokes
apart, I was really impressed with all the questions: they showed a great
interest and knowledge in science and technology and gave me great hope for
our future generations of scientists and engineers. Keep up the great work,
girls and boys.

73,

Samantha Cristoforetti – IZ0UDF

Fox-1A Launch Date Update

Hej! 
Lite goda nyheter från  Nordamerika. 
mvh  Håkan  SM7WSJ
AMSAT has received a launch date for the Fox-1A satellite. Fox-1A will
be launched on August 27, 2015 on a United Launch Alliance Atlas 5
rocket from Vandenberg Air Force Base, California on the NROL-55 flight
for the U.S. National Reconnaissance Office. The launch time has not
been announced.

Fox-1A Operating Frequencies include:

Uplink 435.180 MHz FM
Downlink 145.980 MHz FM

The AMSAT Fox series of satellites will include additional opportunities
for launch during 2015-2016:

+ Fox-1B will fly with the Vanderbilt University radiation
experiments expected in 2016.

+ Fox-1C* will launch on Spaceflight’s maiden mission of the
SHERPA multi-cubesat deployer during the 3rd quarter of 2015.

+ Fox-1D is a flight spare for Fox-1C. If not needed as a spare
it will become available to launch on any open launch slot which
becomes available and be submitted in a Cubesat Launch Initiative
(CSLI) proposal in 2015.

+ Fox-1E is built as a flight spare for Fox-1B but has been included
in a student science proposal as part of the November, 2014 CSLI
for an ELaNa flight slot. If selected the Fox-1B spare will fly as
Fox-1E.

* The flight for Fox-1C has been purchased by AMSAT. It is not funded by
the Cubesat Launch Initiative ELaNa program. Fund raising for the
$125,000 launch costs for Fox-1C are underway. We have commissioned a
unique challenge coin for donors who have contributed at the $100 level
or higher. This challenge coin is shaped as an isometric view of a Fox-1
CubeSat, complete with details such as the stowed UHF antenna, solar cells,
and camera lens viewport. Struck in 3mm thick brass, plated with antique
silver, and finished in bright enamel, the coin is scaled to be
approximately 1:4 scale, or 1 inch along each of the six sides. The reverse
has the AMSAT Fox logo.

FO-29 med enkla medel

Jag har fällt ned min  VHF mast för lite antennarbete och passade då på att provköra några kontakter med enkla medel.

10 el

Jag monterade upp min satellitrotor på ett litet rör 1,5 meter över backen samt satte dit en 10 EL på 70 cm. För sändning använde jag en vanlig 5/8 GP på taket.

När jag precis skulle förlora satelliten så körde jag OH8MBN med  5-5 i rapport och vi hade båda två satelliten på ett avstånd i närheten av 3000 km.

Fo-29

Ett litet tänkvärt experiment som visar att man med enkla medel kan montera en liten minimast i trädgården med all elektronik lättåtkomlig och ändå göra bra resultat.

SHIN-EN2 blir Oscar 82

Då har vi fått en ny satellit med Oscar-nummer!

William A. (Bill) Tynan, W3XO, OSCAR Number Administrator has
confered on SHIN-EN2 the designation Fuji OSCAR-82 or FO-82.

In reply to Seiji Fukushima’s, JH6RTO, request for an OSCAR number,
Bill said, “I along with all in AMSAT-NA and the world’s Amateur
Radio satellite community congratulate you and all involved with Fuji
OSCAR-82 and trust that it will fulfill all of its mission
objectives. FO-82 joins an illustrious line of Fuji spacecraft built
and launched by Japan.”

Shin-En2 is a 17 kg satellite measuring 490×490×475 mm built by
students at Kagoshima University in Japan which will carry a 145 to
435 MHz linear transponder into a deep space orbit.

The aims of the mission are:
* To establish communication technologies with a long range as far
as moon.
* To establish a new technology of the ultra-light-weight satellite.
Proposing a WSJT 29dBm UHF downlink and a 29dBm 20 kHz linear
transponder and a CW beacon all on UHF with a VHF uplink for the
transponder

The orbit will be quite different from the previous satellites. Shin-
En2 will have an elliptic orbit around the Sun and travel to a deep
space orbit between Venus and Mars. Its inclination will be almost
zero, which means Shin-En2 will stay in the Earth’s equatorial plane.

The distance from the Sun will be between 0.7 and 1.3 AU. An
Astronomical Unit (AU) is 149,597,871 km.

Shin-En2 IARU coordinated frequencies:
* 437.505 MHz CW beacon
* 437.385 MHz WSJT telemetry
* Inverting SSB/CW transponder
– 145.940-145.960 MHz uplink LSB
– 435.280-435.260 MHz downlink USB

Shin-En2 launched in the 4th quarter of 2014 with another amateur
radio satellite, ARTSAT2:DESPATCH, on a H-IIA rocket with the
asteroid explorer Hayabusa 2 as the main payload.
