ARISS SSTV Joins with NASA On The Air for a Special Event
Oct. 19, 2018:
Amateur Radio OnThe International Space Station (ARISS) is planning a very special Slow Scan TV event currently scheduled to start October 27 about 10 am UTC. Helping to support the event will be NASA’s Space, Communication and Navigation (SCaN) Dept.
The Space Communications and Navigation (SCaN) program manages NASA’s three most important communications networks. The Space Network (SN), Near Earth Network (NEN), and the Deep Space Network (DSN.
Just as in past ARISS SSTV commemorations, 12 images will be downlinked, but this time with 6 featuring the SCaN educational activities while the other 6 images will commemorate major NASA anniversaries, ie when NASA was established, astronauts first landing on the moon, etc.
In addition to the fun of receiving these images, participants can qualify for a special endorsement for the NASA On The Air (NOTA) celebration event. To learn more about NOTA, visit ( https://nasaontheair.wordpress.<wbr />com).
Once received, Images can be posted and viewed athttp://www. spaceflightsoftware.com/ARISS_<wbr />SSTV/index.php .The transmissions are expected to be broadcast at the usual frequency of 145.800 MHz using the PD-120 SSTV mode.
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.
