ARISS 40th Anniversary event starting Dec 16

 ARISS is celebrating 40 years of human tended operations from space. STS-9 was the first time amateur radio was operated by a person while on orbit back in late 1983. To commemorate that beginning, an SSTV activity has been scheduled to start on Dec 16 about 10:15 UTC and run until December 19 around 18:00 UTC.

Operations will be on the standard 145.800 MHz downlink using SSTV mode PD120.

Received images can be posted at the ARISS Gallery. You can also apply for the an award at the  ARISS SSTV award site.

** UPDATE - Dec 16**

Sadly, seeing reports of nothing heard. Even the crew tried to listen using the COL ham radio. Looks like some additional troubleshooting will be needed to get the system working properly.

**UPDATE - Dec 19**

Still nothing heard (thanks for all the reception report postings) and the event is scheduled to conclude about 18:00 UTC today. Hopefully they can resolve the issue and we can try again soon.

MAI-75 SSTV targeting Dec 7 and 8

Now that the SSTV system in the Service Module appears to be back in working order, it looks like MAI will have some SSTV on Dec 7 and 8 during Moscow passes. The current periods of planned activity are:

Setup and activate Dec 7 about 08:55 UTC
Turn off Dec 7 about 14:25 UTC
 
Activate Dec 8 about 08:15 UTC
Turn off and tear down Dec 8 about 14:10 UTC

These should be the standard PD120 format transmitting with gaps of 2 minutes and using 145.800 MHz.

Reminder - No ARISS award will be available for this session since it is not transmitted globally (just a few of the daily orbits) .

**UPDATE** Nov 28.

It appears the theme for this session will highlight one of MAI's cosmonaut graduates - Yuri Usachov.

**UPDATE** Dec 7.

Several stations reporting nothing heard and the event time is concluded. Hoping that they resolve the issue and have better luck tomorrow.

Verification test - Oct 27-Nov 1

   The SSTV system in the Service Module will again attempt to verify a replacement piece of hardware during the period of Oct 27 until Nov 01. The system will be off around the required period of no transmissions during the planned EVA on Oct 31. Images will be transmitted on 145.800 MHz and in the typical PD120 format. Images can be posted to the Gallery.

Since this is a test of replacement components of the system, there still may be unexpected outages or issues.

Verification test Oct 3-5

  The SSTV system in the Service Module which has been down due to a component failure will be activated from Oct 3-5 to verify a replacement piece of hardware. Images will be transmitted on 145.800 MHz and in the typical PD120 format. Images can be posted to the Gallery.

Since this is a test of replacement components of the system, there may be unexpected outages or issues.

UPDATE - Oct. 4.

Seems there were some odd behavior by the radio so the test has been suspended to try and better understand the issue. Looks like they will have to try again a bit later in the month.

Short duration SSTV experiment (July 26, 2023) - part of Eastern North America

 Below is the press release from ARISS. This is an experiment for the ARRL Teacher Institute and will consist of one image sent several times. A clear uplink frequency is requested.

Special SSTV Experiment Scheduled for ARRL Teacher’s Institute

July 18, 2023— Amateur Radio on the International Space Station (ARISS) in collaboration with the American Radio Relay League (ARRL), plan to carry out a special Slow Scan TV (SSTV) experiment from the ISS on Wednesday, July 26, 2023. During the event, the Columbus Module Repeater, transmitting at 437.800 MHz, will carry a message to be received by teachers attending the ARRL Teacher’s Institute class. The pass will be over the Mid-Atlantic / New England area with transmissions scheduled to begin at 20:05 UTC (16:05 ET) and ending at 20:20 UTC (16:20 ET). If necessary, a backup window will be 21:40 UTC (17:40 ET) to 21:55 UTC (17:55 ET).

Radio enthusiasts are welcome to download the message and follow along with the event, but we ask that all hams please refrain from using the repeater for voice contacts during the event. 

Please understand this is a special experiment conducted through ARISS and the ARRL. All regular operation of the repeater should continue to take place in voice mode only.

About ARISS:

Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab-Space Station Explorers, Amateur Radio Digital Communications (ARDC) and NASA’s Space Communications and Navigation program (SCaN). The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.

SSTV status - 2023

 As many are aware, there was a hardware failure on the older SSTV system operating from the Russian segment of the ISS. A replacement and upgraded system is currently going through ground verification and certification. The intended delivery and installation on the ISS of that new system is during the summer of 2023. 

Hoping to have more specifics as we get a bit closer to the middle of the year.
