ARLS008 ARISS to Celebrate 20th Anniversary with SSTV Event

The Amateur Radio on the International Space Station (ARISS) program is
planning a slow-scan television (SSTV) event starting on Thursday, July 20, and
continuing for 2 days, to commemorate its 20th anniversary. Transmissions, set
to get under way around 2125 UTC, will feature 12 images from past and present
ARISS activities. The SSTV signal should be available nearly anywhere on the
globe at some point during the event.

"Starting with our first meeting in November 1996, our joint operations on Mir,
becoming the first operational payload on ISS in November 2000, to our [more
than 1,100] school contact (so far), ARISS's accomplishments have been
tremendous," ARISS International Chair Frank Bauer, KA3HDO, said, in first
announcing the SSTV event last. "We have touched the lives of many and inspired
and educated countless students to pursue science, technology, engineering, and
math careers."

The event plans to use a computer on the ISS Russian Segment, which stores
images that are then transmitted to Earth using the onboard Kenwood TM-D710
transceiver, the ARISS announcement explained. Those receiving the images can
post them for public viewing.

SSTV signals will be transmitted on 145.80 MHz using FM. The SSTV mode is
expected to be PD120, with PD180 as a possible second option. Free SSTV decoder
software is available on the Internet.

ARISS asked educators to consider ways in which they might use this opportunity
to inspire their students by having them take advantage of this chance to
capture images directly from space to their computers.

All ARISS events are dependent on other activities, schedules, and crew
responsibilities on the ISS and are subject to change at any time. News and
updates are on the ARISS website at, http://www.ariss.org/, the AMSAT website
