JAMBOREE ON THE AIR - KF5AQG IS PLANNING TO BE ON THE AIR FROM THE INTERNATIONAL SPACE STATION AS NA1SS

If you are planning on participating in this weekend’s Jamboree On the Air (JOTA), take note: Astronaut Mike Fossum, KF5AQG, is planning to participate in JOTA from the International Space Station, using the call sign NA1SS. According to the AMSAT website, Fossum’s schedule is somewhat flexible on the weekends, but he will not be available for every pass. The typical crew work periods are 0800-1930 UTC, but they are sometimes available a bit later. When available, Fossum will be operating on the standard ISS frequencies. In the US and elsewhere in IARU Regions 2 and 3, the uplink is 144.49 MHz. In Region 1, the uplink is 145.200 MHz. The worldwide downlink for NA1SS is 145.800 MHz.

NOAA's Atlantic hurricane season update calls for increase in named storms

Forecasters have higher confidence for an active season

August 4, 2011

NOAA issued its updated 2011 Atlantic hurricane season outlook today raising the number of expected named storms from its pre-season outlook issued in May. Forecasters also increased their confidence that 2011 will be an active Atlantic hurricane season. NOAA’s Climate Prediction Center, a division of the National Weather Service, updates its Atlantic hurricane season outlook every August.
“The atmosphere and Atlantic Ocean are primed for high hurricane activity during August through October,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at the Climate Prediction Center.  “Storms through October will form more frequently and become more intense than we’ve seen so far this season.”
Key climate factors predicted in May continue to support an active season. These include: the tropical multi-decadal signal, which since 1995 has brought favorable ocean and atmospheric conditions, leading to more active seasons; exceptionally warm Atlantic Ocean temperatures (the third warmest on record); and the possible redevelopment of La Niña.  Reduced vertical wind shear and lower air pressure across the tropical Atlantic also favor an active season.
Based on these conditions and on climate model forecasts, the confidence for an above-normal season has increased from 65 percent in May to 85 percent. Also, the expected number of named storms has increased from 12-18 in May to 14-19, and the expected number of hurricanes has increased from 6-10 in May to 7-10.
Across the entire Atlantic Basin for the whole season – June 1 to November 30 – NOAA’s updated seasonal outlook projects, with a 70 percent probability, a total of:

• 14 to 19 named storms (top winds of 39 mph or higher), including:
• 7 to 10 hurricanes (top winds of 74 mph or higher), of which:
• 3 to 5 could be major hurricanes (Category 3, 4 or 5; winds of at least 111 mph)

These ranges are indicative of an active season, and extend well above the long-term seasonal averages of 11 named storms, six hurricanes and two major hurricanes.
The Atlantic basin has already produced five tropical storms this season: Arlene, Bret, Cindy, Don and Emily. All eyes this week are on Emily, which continues to develop and move towards the United States.
The last hurricane to make landfall in the United States was Ike in 2008. Last year saw above-normal hurricane activity, but none made landfall in the United States. August through October are peak months of the Atlantic hurricane season, and FEMA urges people not to be lured into a false sense of security by the lack of hurricanes so far this year.
"It is still early in this hurricane season and we know it can take only one storm to devastate communities and families," said FEMA Deputy Administrator Rich Serino. "Many disasters come without warning, but that’s not the case with hurricanes. This is hurricane season, if you haven't already, now is the time to take a few simple steps to get you and your family prepared. Anyone can visit www.ready.gov to learn more."
Be prepared for the hurricane season with important information available online at hurricanes.gov/prepare and at FEMA’s ready.gov.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.

Russian Spacewalkers to Move Cargo Boom, Deploy Ham Radio Satellite

07.29.11

› View hi-res image
Two Russian cosmonauts will leave the confines of the International Space Station on Aug.3 to move a cargo boom from one airlock to another, install a prototype laser communications system and deploy an amateur radio micro-satellite.

Expedition 28 Flight Engineers Sergei Volkov and Alexander Samokutyaev are scheduled to venture outside the Pirs airlock at 10:30 a.m. EDT Wednesday to begin the six-hour excursion. Both spacewalkers will wear Russian Orlan-MK spacesuits. Coverage of the spacewalk will be broadcast live on NASA Television beginning at 10 a.m. EDT.

Volkov, making his third spacewalk, and Samokutyaev, making his first, will both wear spacesuits marked with blue stripes. Volkov’s previous two spacewalks occurred while he was Expedition 17 commander in 2008.

During the spacewalk, Commander Andrey Borisenko and NASA Flight Engineer Ron Garan will close the hatches on the Poisk docking module, which is opposite the Pirs airlock, and seal the hatches between Zvezda and Poisk. This gives them access to their Soyuz 26 spacecraft, protects against the unlikely possibility of a sudden station depressurization and allows the forward transfer compartment of Zvezda to be used as a backup airlock. Flight Engineers Mike Fossum of NASA, and Satoshi Furukawa of the Japan Aerospace Exploration Agency, will be in the U.S. segment and will have access to their Soyuz 27 spacecraft, which is docked to the Rassvet module.

The duo’s first task will be to deploy a boxy, 57-pound satellite, called alternately ARISSat-1 and Radioskaf-V, which is the prototype test flight of a proposed series of educational satellites being developed in a partnership with the Radio Amateur Satellite Corp. (AMSAT), the NASA Office of Education ISS National Lab Project, the Amateur Radio on ISS (ARISS) working group and RSC-Energia.

The ARISSat design can carry up to four student experiments and the data from these experiments will be transmitted to the ground via an amateur radio link. This prototype ARISSat-1 carries one student experiment, a pressure sensor built at Kursk University in Russia, to measure atmospheric pressure for the lifetime of the satellite.

In addition to transmitting student experiment data, ARISSat-1 will transmit still-frame video Earth views from four onboard cameras, commemorative greetings in the native languages from students around the world, including messages to commemorate the 50th anniversary of the launch of Russian cosmonaut Yuri Gagarin as the first human in space. The satellite, which uses off-the-shelf equipment and software provided by AMSAT, also features a Morse code tracking beacon and will function as a space communications utility for use by “ham” radio operators world-wide.

More information on tracking ARISSat-1 decoding its telemetry visit the AMSAT and ARISSat-1 websites:

http://www.arissat1.org/v3/

http://www.amsat.org/amsat-new/

Their next job will be to install a barbecue grill-shaped experiment to test the use of a laser-based system for high-speed transmissions at up to 100 megabytes a second to the Earth from Russian science experiments. The system will be installed on a universal work platform outside the Zvezda service module hull just behind its solar arrays.

After that, they’ll take photographs of a nearby antenna that has been showing signs of degraded performance. The imagery will be used to help engineers on the ground find the root cause of the antenna’s problem.

Next, they’ll retrieve an antenna that was used for docking of the Poisk module when it arrived at the station in November 2009. The antenna is no longer needed and will be brought back inside the station.

Then it is on to the major objective of the spacewalk, the move of the telescoping STRELA-1 cargo boom from the Pirs docking compartment to the Poisk docking compartment. The task is expected to take nearly three hours to complete, and will involve the use of the STRELA-2 boom, with its base attached to Pirs. At the completion of the task, STRELA-1 will be ready for use from Poisk, and STRELA-2 will remain on Pirs. The cargo booms extend somewhat like a fishing rod, and can be used to help move massive components around the outside of the Russian segment of the space station.

Once the boom relocation is complete, the spacewalkers will retrieve an experiment known as Biorisk from the airlock, and install it on a handrail outside the Pirs module. Biorisk is short for the Influence of Factors of the Space Environment on the Condition of the System of Microorganisms-Hosts Relating to the Problem of Environmental Safety of Flight Techniques and Planetary Quarantine. The experiment will look at the effects of bacteria and fungus on structural materials used in spacecraft construction with a focus on how solar activity may affect the growth of these microbes.

With all tasks complete, Volkov and Samokutyaev will take some final photographs, reenter the Pirs airlock and end their spacewalk.

The next Russian spacewalk is planned for February 2012, when the Expedition 30 crew will be in orbit aboard the station.

PRUEBAS DE ARISSAT-1 EL 30 DE JULIO A LAS 19:15 UTC ***ACTUALIZADO***

Muy buenas tardes a todos los colegas radioaficionados

Durante una teleconferencia internacional de ARISS, Sergey Samburov  RV3DR  indica que el Satélite ARISSat-1, actualmente abordo de la ISS, tendrá cargadas sus baterías para fin del mes de Julio de 2011.

Según Samburov las pruebas serán relizadas con el Satélite abordo de la ISS, caso de algún ajuste necesario, iniciándose a las 19:15 UTC del 30 de Julio de 2011 hasta las 12:00 o 14:00 UTC del 31 de Julio de 2011.

El satélite transmitirá en la frecuencia de 437.550 MHz. Ya publicamos la tabla de frecuencia, pero en correo aparte se repetirá para que aquellos que no la observaron, la guarden como referencia por la diversidad de frecuencias y modos.

Estamos atentos para el desplazamiento de éste nuevo satélite desde la ISS que será en Agosto de 2011.

ARISSat-1/KEDR Deployment Timeline
Driven by ISS Schedules

 ARISSat-1/KEDR On Air Test Begins July 30

During the July 13, 2011 International ARISS teleconference Sergey Samburov, RV3DR announced that the ARISSat-1/KEDR battery will be charged in late July. A test of the system will be conducted on the ISS from 1915 UTC July 30 to about 1200-1400 UTC July 31. The standard ARISSat-1/KEDR 2m downlink band plan should be transmitted. The satellite FM signal will also be downlinked on 437.55 MHz.

During the test ARISSat-1/KEDR will be in LOW power mode, this means that it will transmit about 40 seconds and then shut down for 2 minutes and then transmit for 40 seconds. The linear transponder mode will be activated once the satellite is deployed.

ARISSat-1/KEDR Project Manager Gould Smith, WA4SXM said the preparation procedures include the battery being charged and assembled into the satellite. Gould, along with ARISS Hardware Engineer Lou McFadin, W5DID participated in an earlier teleconference call with NASA to review the Roscosmos EVA procedures for the release of ARISSat-1/KEDR during Russian EVA 29. The procedures to remove the protective quilts from the solar cells and turning on the safety switches prior to deployment were reviewed during this call.

EVA for ARISSat-1/KEDR Deployment Planned for August 3

Gould summarized, "As of July 16 we are looking at an August 3, 2011 date for EVA 29 and the ARISSat-1/KEDR deployment, subject to change due to ISS schedules. During our review we noted the ARISSat/KEDR deployment is the first task of the EVA, so it will occur fairly soon after the EVA begins. We will let everyone know more as we know more."

145.950 MHz FM Downlink
FM transmissions will cycle between a voice ID as RS01S, select telemetry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.

435 MHz - 145 MHz Linear Transponder
The linear transponder will operate in Mode U/V (70 cm Up, 2m Down). It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink. This mode is designed to work with low power transmitters and omni antenna.

145.919 MHz/145.939 MHz CW Beacons
The CW transmissions will be callsign ID RS01S, select telemetry, and callsigns of people actively involved with the ARISS program.

145.920 MHz SSB BPSK-1000 Telemetry
The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will transmit satellite telemetry. When the CW2 beacon on 145.919 MHz is active this indicates that the BPSK-1000 format is being transmitted. If the CW1 beacon on 145.939 MHz is active this indicates the backup of BPSK-400 format is being transmitted.
