ARISS is planning another of their popular Slow Scan Television (SSTV) experiment events. Transmissions on 145.800 MHz FM are scheduled to begin Friday, Feb. 15 at 08:45 UT and run through Sunday, Feb. 17 at 17:25 UT.

SSTV operations is a process by which images are sent from the International Space Station (ISS) via ham radio and received by ham operators, shortwave listeners and other radio enthusiasts on Earth, similar to pictures shared on cell phones using twitter or instagram.

When this event becomes active, SSTV images will be transmitted from the ISS at the frequency of 145.800 MHz using the SSTV mode of PD120 and can be received using ham radio equipment as simple as a 2 meter handheld radio or a common shortwave or scanner receiver the covers the 2 meter ham band. After connecting the audio output of the radio receiver to the audio input of a computer running free software such as MMSSTV, the SSTV images can be displayed.

Transmissions will consist of eight NASA On The Air (NOTA) images (see https://nasaontheair.wordpress.com/). In additional, four ARISS commemorative images will also be included.

Once received, Images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php . In addition, you can receive a special SSTV ARISS Award for posting your image. Once the event begins, see details at https://ariss.pzk.org.pl/sstv/ .

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. Please check for news and the most current information on the ARISS Twitter feed @ARISS_status or the AMSAT Bulletin Board

The SSTV images will be transmitted in PD-120 on 145.800 MHz FM using the Kenwood TM-D710 transceiver located in the Russian ISS Service module.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

You can receive the SSTV transmissions by using an Online Radio (WebSDR) and the MMSSTV software:
• Listen to the ISS when it is in range of London with the SUWS WebSDR http://farnham-sdr.com/
• Listen to the ISS when it is over Russia with the R4UAB WebSDR http://websdr.r4uab.ru/

Crew Studies Human Body and Checks Cooling Systems

Wednesday saw the Expedition 58 crew explore the inner workings of the human body in space and maintain cooling systems aboard the International Space Station.

NASA astronaut Anne McClain spent all day setting up cooling gear inside the U.S. Destiny lab module and Japan’s Kibo lab module. She drained and refilled water pumps inside the Fluid System Servicer and the Internal Thermal Control System. The life support systems help cool the station’s atmosphere and dispel heat generated by electrical systems.

Microgravity’s impact on the human physiology was the focus of Flight Engineer David Saint-Jacques’ day. The Canadian Space Agency astronaut collected and stowed his breath, blood and urine samples for a variety of human research experiments. The research is supporting the long term-collection of human biological samples and observing bone marrow and blood changes.

Saint-Jacques also conducted ultrasound scans in the Zvezda service module for the Fluid Shifts study with assistance from Commander Oleg Kononenko and doctors on the ground. That research is seeking to reverse increased head and eye pressure that occurs in space.

Kononenko started Wednesday servicing Russian life support systems. The four-time station resident then spent the afternoon on more space research studying motion coordination, radiation exposure and crew psychology.
