Possible ARISS SSTV operation before year's end

*ARISS* reports the possibility of a worldwide commemorative SSTV operation
from the International Space Station on Friday, Dec. 27 or Saturday, Dec.
28 and following days.

The SSTV downlink frequency is 145.800 MHz. ARISS will provide more
information as it becomes available. Watch the amsat-bb and follow
@ARISS_status on Twitter for updates.

An SSTV system is an integral part of one of the ARISS ham radio stations,
NA1SS/ RS0ISS in the Service Module. It transmits and receives JPEG still
images. This system utilizes the Kenwood D700 and D710 radios and the ARISS
antennas mounted on the Service Module.
The SSTV equipment also includes SpaceCam and MMSSTV software, a
radio/computer interface module and data cables. A Kenwood VC-H1 is also
used to provide near real-time automatically transmitted images once every
3 minutes, when active.

A Kenwood D710 radio located in the Service Module was deployed by the
Russian Space Agency, Energia to provide extended support of imaging
experiments using various SSTV formats. It employs SpaceCam and MMSSTV
software to transmit stored images.

The current Expedition 61 crew aboard the ISS includes Dr. Andrew “Drew�
Morgan, KI5AAA, an emergency physician in the U.S. Army; veteran pilot
Cosmonaut Alexander Skvortsov, RK6ATR; Luca Parmitano, KF5KDP, an Italian
Air Force officer, pilot, and engineer; pilot Cosmonaut Oleg Skripochka;
biologist Dr. Jessica Meir; and electrical engineer Christina Koch.
