SPACEWALK FROM INTERNATIONAL SPACE STATION WILL AIR ON NASA TV
HOUSTON -- Two Russian cosmonauts will step outside the International
Space Station on Wednesday, Feb. 16. They will install and retrieve
experiments on the Russian segment of the complex and deploy a small
ham radio satellite. NASA Television coverage of the spacewalk will
begin at 6:45 a.m. CST.
Expedition 26 Flight Engineers Dmitry Kondratyev and Oleg Skripochka,
wearing their Russian Orlan spacesuits, will emerge from the Pirs
Docking Compartment airlock for the second time in four weeks at
about 7:15 a.m.
During the nearly six-hour spacewalk, they will install two
experiments. One will collect information useful in seismic forecasts
and earthquake predictions, and the second will look at gamma
splashes and optical radiation during terrestrial lightning and
thunderstorms. The spacewalkers also will retrieve a pair of panels
exposed to space as part of an experiment to identify the best
materials for building long-duration spacecraft.
The cosmonauts also will deploy an experiment called ARISSat-1, or
Radioskaf-V, a boxy 57-pound nanosatellite that houses congratulatory
messages commemorating the 50th anniversary of Yuri Gagarin's launch
to become the first human in space. The ham radio transmitter will
enable communications with amateur radio operators around the world
for three to six months. It is the first of a series of educational
satellites being developed in a partnership with the Radio Amateur
Satellite Corp.; the NASA Office of Education International Space
Station National Lab Project; the Amateur Radio on the International
Space Station working group; and RSC-Energia.
The spacewalk will be the second for Kondratyev, who will wear the
spacesuit marked with red stripes, and the third for Skripochka, who
will wear the suit with blue stripes.

Hi!
I was planning on returning to Phoenix after the just-concluded AO7 pass,
but will extend my stay out here. I will drive back to the DM32xx/DM42ax
boundary for the VO52 pass at 0313-0326 UTC. This is a nice pass, up to
max elevation of 40 degrees. Once this pass wraps up, it's back home
to Phoenix. It will be dark, except for my lights and the traffic
on a nearby highway and rail line.
I will try to start out around 145.910 MHz +/- on the VO52 downlink, but
may have to move around due to QRM or QRN. I don't work many VO52 passes
in the evenings, so this will be interesting.

ARISSat-1 Update - No Wednesday Deployment of ARISSat-1
AMSAT News Service Bulletin 044.01
>From AMSAT HQ SILVER SPRING, MD.
February 13, 2011
To All RADIO AMATEURS
BID: $ANS-044.01
1. On Wednesday, 9 FEB 11 NASA announced that ISS Russian Segment
(RS) EVA28 will be broadcast live on NASA TV, starting at 1245 UTC
on Wednesday, 16 FEB 11. Included in the schedule for RS EVA28
posted by NASA was the deployment of ARISSat-1/RadioSkaf-V/Kedr
RS EVA 28 is being managed by RSC-Energia, the operating entity
of the ISS RS, as well as the Soyuz and Progress vehicles.
2. On Thursday, 10 FEB 11 RSC-Energia finalized plans to perform
a preliminary test of ARISSat-1 while inside the ISS to verify
that the satellite could transmit following its delivery to the
ISS on a Progress resupply vehicle.
This was not an event that was previously scheduled. Instructions
were sent to the Cosmonauts to give them a test procedure with
activation scheduled for that day at 1605 UTC. For this test, the
ARISSat-1 VHF antenna port was connected to an RF patch panel
inside of the Zvezda Service Module, to provide an RF connection
of the satellite to one of the four ARISS external antennas mounted
on the aft end of the Service Module. ARISSat-1 was then activated
and the Cosmonauts listened for the satellite's FM transmissions
using the Kenwood TM-D700(E). This radio is normally used for ARISS
school contacts which is connected to an adjacent ARISS external
antenna.
During the test, RSC-Energia decided to keep the transmitter on
until Friday morning. AMSAT was notified Friday morning that the
cosmonauts reported that tests were nominal. A number of ground
stations reported hearing the transmissions as well, including
AMSAT VP-Engineering Tony Monteiro, AA2TX in North Andover, MA.
This preliminary test was not announced to amateurs in advance
due to the short time frame between RSC-Energia's decision to
conduct this test and when it was conducted as well as the
uncertainty as to how long the satellite's transmitter would
remain activated.
3. AMSAT learned on Friday morning, 11 FEB 11 that the deployment
of the ARISSat-1 satellite had been removed from the RSA EVA 28
timeline by RSC-Energia management. NASA was informed that the
ARISSat-1 deployment would be deferred to a later RS EVA, due to
changes in the tasks associated with the configuration of RS pay-
loads to be performed during RS EVA 28. Subsequently, RSC-Energia
informed NASA that deployment of ARISSat-1 will be added to RSC
EVA 29 currently scheduled for July 2011.

ARRISat-1 Team Pointers to Get Ready for SSTV Reception
AMSAT News Service Bulletin 044.02
>From AMSAT HQ SILVER SPRING, MD.
February 13, 2011
To All RADIO AMATEURS
BID: $ANS-044.02
The ARISSat-1 FM downlink on 145.950 MHz includes live SSTV
images as part of the cycling voice ID, select spoken telemetry
values, and the international greeting messages. The recently
announced schedule delay for ARISSat-1 deployment gives every
one time to begin station improvements to receive SSTV pictures
from orbit.
One fun feature is that there are four SSTV cameras mounted on
the spacecraft. On photos of ARISSat-1 you may have noticed black
brackets on the outside of the spacecraft. These hold the mirrors
that reflect the light onto the lens of the cameras. The software-
defined-transponder will use the image data from the cameras to
generate the SSTV downlink.
ARISSat's software will sequentially select a new or stored image
from one the four cameras. There are two pre-recorded images as
part of the sequence. The camera that took the the picture can be
identified by the color of the call sign in the upper left of the
SSTV image. The SSTV image will be sent down as FM audio SSTV in
Robot 36 format on 145.950 MHz about every 140 seconds.
The RF downlink power on the 145.950 MHz FM downlink will be 250mW
which is predicted to provide a link margin around 6 dB on an HT
with a 'big whip' when the satellite is at 15 degrees elevation. This
should be sufficient to receive SSTV pictures although you may need
to orient the whip to line up the antenna polarization.
ARISSat-1 is not stabilized so the antenna orientation is unpredict-
able and a certain amount of fading will happen. The receiving link
margin may be improved with a handheld beam such as an "Arrow", "Elk",
or "Cheap Yagi" antenna.
(See: http://www.wa5vjb.com/references/Cheap%20Antennas-LEOs.pdf)
General Overview Radio-to-Soundcard Interface
---------------------------------------------
To view the SSTV downlink from ARISSat-1 you'll need a computer
running SSTV software for your soundcard and an audio connection
between your radio and the computer.
If you are already on the air with other amateur radio soundcard
applications chances are you are ready to receive ARISSat's SSTV
downlink with little or no modification to your setup.
The audio from the radio to the computer is the key link. An initial
"Receive Only" configuration is easily done consisting of an audio
patch cable between your radio and the soundcard. Take the speaker
or headphone output from the radio and run it into the line (or mic)
input on your PC sound card.
Setting the level is simple also as the MMSSTV software has a bar
indicator. Just adjust the sound card gain slider and/or radio volume
control so that the SSTV signal is within the center part of the bar.
MMSSTV will give you an "overflow" indication if the volume is too
high.
If your rig has a 'Line Out' connection this can be run to the
soundcard 'Line In'. Using the radio 'Line Out' you won't have to
deal with the interaction of the radio's volume control with the
soundcard levels. But you will still need to use the soundcard
'Volume Control' to set the 'Line In' levels.
SSTV Software Download Sites
----------------------------
There are many amateur radio SSTV software decoding applications
available. One of the easiest to use on Windows computers is the
MMSSTV program. This can be downloaded from:
http://mmhamsoft.amateur-radio.ca/pages/mmsstv.php
MMSSTV installs like most other Windows software. The download
site has audio test files for you to learn with. If you have an
HF rig the SSTV crowd hangs out 14.230 MHz and you can use their
signals for testing and learning.
MMSSTV will also automatically determine which SSTV protocol is in
use. You won't need to remember Robot 36 if you set MMSSTV's RX mode
to 'Auto'.
SSTV software for the Mac is available at:

Opportunity for Students to Participate on "Extra" Shuttle Mission

BID: $ANS-044.07
UniverseToday published a news item (http://tinyurl.com/6dnjp4e)
with a new opportunity for students to be part of history and fly
an experiment on what could be the last space shuttle mission. The
program is the Student Spaceflight Experiments Program (SSEP) for
the STS-135, the shuttle mission that might fly in June of 2011.
SSEP is a new program that launched in June 2010 by the National
Center for Earth and Space Science Education in partnership with
NanoRacks, LLC, a company that is working with NASA under a Space
Act Agreement as part of the utilization of the International
Space Station as a National Laboratory.
The company hopes to stimulate space station research by providing
a very low-cost 1 kilogram platform that puts micro-gravity projects
within the reach of universities and small companies, as well as
elementary and secondary schools through SSEP. So, this is actually a
commercial space program and not a NASA program.
This opportunity offers real research done on orbit, with students
designing and proposing the experiments to fly in low Earth orbit.
According to the National Center for Earth and Space Science Educa-
tion, "We hope to get 50 communities and 100,000 students participa-
ting in the initiative which allows grade 5-14 student design of real
experiments to fly aboard Atlantis, and engages entire communities,"
But it is now time critical for schools to be able to participate.
There is a proposal submission deadline of May 12, 2011. By the end
of May, the flight experiments will be selected, so that NASA can be
provided with the materials list 3 months in advance of launch.

I have some recordings but I am not sure they will be of much use.
However I thought it might be useful to share my experiences with the
telemetry.
I monitored the audio downlink on the first two passes and the data downlink
on three passes. I used the ARISSATtlm-0.47 software for decoding on the
data passes.
On the first pass I could not clearly see the CW signal on the tuning
indicator so no decode of the CW or data. The next two pass I had good CW
decode and could line up the CW signal OK but no decode. After the passes
(naturally) I re-read the article in the AMSAT journal and realized the
importance of the 48k, 16 bit sample rate. The article claims that the
ARISSATtlm configures the sound card to these values but when I checked the
sound card was still at my normal 44.1k sample rate. Perhaps the software
sets it to 48k and then sets it back to its previous value but I suspect
not.
I re-sampled my recording at 48k but still no decode. I noticed also that
the CW decode from the recording was not as good as the original so perhaps
the recording was at fault.
To test this re-sampling method I re-sampled the test wave file at 44.1k and
confirmed that it would not decode. I then re-sampled this file at 48k and
once again it would decode.
(i.e. the re-sampling worked OK.) This again perhaps pointed to a problem
with the quality of my recording.
Some observations.
a Make sure the sound card output is set to 48k/16bit.
b I noticed that the live telemetry sounded quite different from the test
wave file. The data signal was much more obvious.
c When running the test file Excel complains that data has been lost from
the CSV file because the number of columns exceeded the 256 column limit.
(Excel opens OK and all 256 columns contain data)
d I notice that when I use the 0.7 software to decode the test file, the
software remains active until I close it. When I attempt to decode my
recordings the software always closes itself when the file ends.

Subject: [amsat-bb] Wanted: ARISSat-1 BPSK1000 recordings
If anyone made a recording of ARISSat-1's BPSK1000 signal (either an SDR
recording or just a regular recording), then I'd like to get a copy.
Please email me if you made a recording of the BPSK1000 signal.

As you may know, KySat-1 along with CubeSats from Montana State University
and University of Colorado, will be launched into orbit from Vandenburg AFB
on February 23 at 0809 UTC. As with all satellite missions, for us,
verifying operation and establishing communication early is critical to
mission success. I would also like to invite amateur radio operators to help
us establish contact with KySat-1. Information about the beacons, the
mission, and the status of the mission can be found at the following link:
http://ssl.engineering.uky.edu/kysat1/
Let me know if you have any questions, and check back later for updates and
changes to the website as we get closer to launch.

Interesting comments:
"During the test, RSC-Energia decided to keep the transmitter on
until Friday morning. "
Hmmm curious about a few things but... what impact this "test" has had on
battery life, considering the vehicle now "sits" until at least July...

I wonder if it will sit until July?
After all the Russians KEDR name reflects the upcoming anniversary of Yuri
Gagarin's flight into space. That was 50yrs ago on 12th April.
So many questions....
