ARISS Contact - Harel Educational Campus, Holon, Israel, telebridge via VK4ISS

This contact is scheduled with crewmember Josh Cassada KI5CRH, using the ISS callsign NA1SS, and will be a telebridge contact via VK4ISS.

Start time is Fri 2022-11-04 09:43:51 UTC

Downlink signals from ISS will be audible above parts of Australia on 145.800 MHz narrowband FM. The conversation will be in English.

The SatNOGS community is encouraged to schedule observations to capture this event!

Afterwards, I’ll add a post that collects the observations, listing the stations and observers that were in the footprint of the ISS for the pass.

School Information:
Harel is a unique school in the sense that it incorporates high spiritual \ religious education with many innovative study trends. It’s a six year boy’s school, starting from class 7 to class 12. It comprises intermediate and high school. Some of the study trends students can choose
from are Communication, Graphic design, Robotics, Cinema, Computers and Literature.The school has achieved many prizes in recent years.
The contact with the ARISS organization was entirely my idea as I, as an English teacher, wanted to promote The CLIL idea and connect studies of Science, Astronomy and English. The students are so looking forward to the meeting with the astronauts with great enthusiasm.

  1. I know you use animals in research. How many animals do you have in space with you right now and how do you take care of them?

  2. Do you practice emergency drills? Can you describe some of the critical incidents that you need to prepare for?

  3. What has been your greatest challenge so far and how did you respond to it?

  4. What are the major research projects you are focusing on and what discoveries have you made?

  5. What do you think the biggest advances will be in the space program over the next ten years?

  6. Have any of the experiments failed or given you totally different results than you expected?

  7. Please describe your years of education and training that led to your assignment on the space station.

  8. What has been the most exciting part of your mission so far?

  9. Can you describe what zero gravity feels like?

  10. Have you done a spacewalk and how does it feel?

  11. Why should we continue to fund expensive space missions when we have more pressing problems on Earth?

  12. How are your experiments helping to save our Earth?

  13. Being in a microgravity environment causes a decrease in muscle mass and bone density. Other than exercise, what measures are you taking to protect your health?

  14. How many days supplies do you have on board should a resupply mission not come on time?

  15. Can you describe the automatic systems on board the ISS to keep you in your current orbit?

  16. Do you ever feel sudden vertigo or claustrophobia whilst you are up in space?

  17. Can you describe how you get into and leave the ISS without losing any air?

  18. How long does it take to prepare for a spacewalk?

  19. Does gravity affect time and ageing?

  20. What is the most amazing thing you have seen in space? 21. Is the sun more powerful in space?


Note, that the default/first selection when Creating a new observation for the ISS is for the APRS repeater on 145.825 MHz, which will not capture this event.

Recommend to use the ISS TransmitterMode V/V FM (crew R1)” (UUID pQRPwTWqQr7unDav5Mz4pG).
There are a few Transmitters in the database with the same downlink frequency and FM modulation, and any will work.


Several stations were able to receive parts of the contact:

Other observations that were scheduled at the last minute (by wiredlab (me)):

What remains for someone to do is to take the audio from each observation and combine into a single recording for the entire contact. Such a combination would yield better signal-to-noise than any individual recording.

This would be a perfect “gift” from the SatNOGS community to the school participants!
