First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active.

Re: Detail on Cache district school contact
by aj9n＠aol.com 06 Feb '23

06 Feb '23

Hi Loren and all, The times that are being posted are being given by ARISS to the schools. The schools are to confirm the times themselves using the very latest Kep data that they have acquired on the day of their contact. The schools have to realize that things can change a few minutes plus/minus from what they may have planned for the event. My latest prediction that I get using the very latest files from Celestrak are showing: AOS 18:45:31 UTC LOS 18:56:12 UTC Max elevation 32 degrees. I am using the exact coordinates that the school gave us for where the event is being held. The software I am using for this prediction is Nova. So it looks like your predictions are very close. Like I have said in earlier emails, the times that show up on the AMSAT-BB are really to be thought of as more of a planning/placeholder time. If there is a major change in the contact time, then the bulletins get updated to reflect that change. I have lost count how many times I have done that. Again, I always say to either run your own Keps or to plan on starting to listen about 10 minutes ahead of what gets posted. I don't try to keep the times updated every day; I am simply too busy with all of the ARISS work to do that. If there is something major, then I posted something. Please also note that depending on the local school location versus terrain, the ISS antenna versus the ISS superstructure itself maybe blocking the signal, and a zillion other reasons; the actual conversation might start 30 to 60 seconds beyond predicted AOS. And the contact might end sooner than expected. We have had a few times where the contact actually got started before predicted AOS. So I always recommend to my schools to start calling the ISS 30 to 60 seconds ahead of predicted AOS and to have the squelch fully off so that they can hear the faintest of signals. Believe it or not, you should hear a slight decrease in the background noise as the signal is working towards full quieting but hear no audio just yet. That's when I know we probably got them, they are calling us, but we just don't hear the audio yet. Wait a few more seconds and then there they are. Once a school hears some actual audio, then you can usually sense a big sigh of relief from the audience. Also in my earlier email, I mention that our lead orbital guy is using Kep data that is not in the public domain. So yes, he is getting data from NASA on what is happening and what is planned to happen. As the contact date and time approaches real time, the latest public domain Kep set is what is in command of the actual prediction. And of course, the ISS is the one really in command as to where it is traveling. Hope this helps. 73,Charlie Sufana AJ9NOne of the ARISS mentors In a message dated 2023-02-06 12:06:27 Eastern Standard Time, amsat-bb(a)amsat.org writes: I actually took the time to set the home location to the GPS coordinates of K7IVM as the home location and I took a screen shot from the website when I was preparing last Tuesday. It clearly shows the home location somewhere near Millville, UT and the AOS being 20-30 seconds before 18:42. Pulling up that same pass today, I see the AOS is 18:45:40 and it still shows the house on K7IVM's location near Millville. I'm pretty certain they've updated their prediction, but I'm just not sure if their earlier prediction was based on a less reliable or older source than the original ARISS announcement, or if the ARISS announcement, when it was first written up (since I've never seen the time waiver) was just lucky to be closer to these more recent predictions from N2YO. I'm not sure where they get their information from, but I just found it a curiosity as I can imagine ARISS having access to more insider info like future burns than would be in public TLEs. -LorenK7IW On Sun, Feb 5, 2023, 03:50 Mark Johns, K0JM <k0jm.mark(a)gmail.com> wrote: N2YO is giving you the AOS time for. your location -- assuming you have it set up properly.

Re: Detail on Cache district school contact

Hi Loren and all, The announcements I post to the AMSAT-BB are a shortened version of a much bigger file. I try not to clutter up the announcements to the AMSAT-BB too much. I do try to keep things updated in near-real time since everything in ARISS happens very very quickly. Within that announcement, I present the schools that have their confirmed contact times (more about that in a moment). In the announcement you will also find a few lines that I am repeating below from my Saturday posting to address the comment about finding the questions: The complete schedule page has been updated as of 2023-02-04 17:30 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt (A side note, Bob Bruninga WB4APR asked me many years ago if I could also have a text file so the file could be sent through easily on a hamsat. I keep this per his request.) If you download one of these 2 files, then you will see the complete listing of the scheduled contact times, the school questions if I have them, and the complete list of the schools that are on our near-term scheduling queue. Some of these schools are about 5 months away from their contact week, some are only a few days out. Just a short word, sometimes I get the questions after the school contact has happened, I post things within 8 to 10 hours of receiving something. The questions are also sent out a few days in advance by Dave AA4KN; another one of the ARISS mentors and PR person. The latest one he sent is labeled ARISS News Release No. 23-04. These releases have the questions as well as a bit more information about the school. Please note, that ARISS does not publish the student names with the questions. We do try to protect the students as much as possible. Now for your question about the contact time that is listed in my announcements. The times you usually see are to be thought of as more of a planning time for the ISS planners. Let me explain more about the process of how a school progresses through our system. When a school gets accepted into the ARISS program to have a scheduled contact, they are first placed into what is known as our Waiting Page (currently there are about 40 schools on this list). These are schools that are often many months to possibly a year or 2 out from a contact. On our Schedule Page (currently there are about 20 schools on this list) are the schools that have waited their turn for other schools to have their contact. These are the ones that we have slotted into a mutually agreed upon week to try and schedule a contact. Think of the Schedule Page as our more near-term contacts list. Roughly about 6 months worth of schools are on this list. We try for 1 contact per week, sometimes that happens, sometimes we get more, sometimes we get none. About a month to 1.5 months out from a school's contact week, the school gets presented a list of date and time options for them to prioritize or reject. So depending on the school location and availability time, the crew schedule, and the ISS orbital mechanics; there may be 2 or 3 possibilities or maybe 7 or 8 or none (in which case we have to change the week). These option times are generated from our ARISS orbital guru (retired NASA) who is actually working with Kep data that is not totally in the public domain. You should think of the times as more of a placeholder/planning time for the ISS planners. As the contact date approaches, the actual contact time starts to jell to a time that might be off from what has been published in the announcements but is using the very latest public domain Kep data. Each school is told to make sure that they keep checking the contact time (our ARISS telebridge stations already know to do this); especially on the day of the actual contact. The latest Kep data that they download is what is in command for the actual time. The ISS is pretty big and thus there is drag which lowers the orbit. So every once in awhile, the ISS gets reboosted; that changes the orbit. And sometimes, the ISS needs to do a collision avoidance maneuver. Hence the Kep data is changing on a daily basis. And sometimes that change happens only a few hours before a contact. Sometimes that change is unplanned. In my postings, I do include this line: Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. I just ran the orbital track using data from Celestrak for Cache County and this is what I am getting: Tuesday 2023-02-07 AOS 18:45:33, LOS 18:56:14 Max elevation 32 degrees. (I will not be able to hear the ISS during this contact time as I am in the Melbourne, FL area.) Here is what I have posted in my latest posting: Contact is go for: Tue 2023-02-07 18:45:54 UTC 32 deg If you want to hear the ISS from your location, then you will need to run your own predictions using your own software (like SatPC32) or any of the on-line prediction sites. Obviously for your own location, you will need to know your longitude, latitude, and elevation. If you want to see the prediction from the school's or telebridge station location, then use the town data that is closest to them. You may be off a few seconds from the school's actual location. By the way, I will not release the actual longitude, latitude, and elevation information that the school is using. The Cache County contact is going to be Live-streamed. Check my postings for the latest link URLs that I have. As always, I do sometimes get very last minute changes that I will try to post for everyone if that happens. I hope this explains things a bit. If you have any questions, please let me or any of the other ARISS mentors and officers know. ARISS is an all volunteer program and many of us put in a large number of hours into the program. With all of the duties I do for ARISS, I spend about 2 to 3 hours average every day (many times it is more like 8 to 9). All of this for about 10 minutes of talk time with a crewmember on orbit and maybe, just maybe changing a student's thinking that this STEM/STEAM stuff might actually be sort of cool and not that nerdy. By the way, ARISS has a booth at the Orlando Hamcation next weekend. Stop by and say hi. If you think this ARISS work is something you might want to be more involved with, just let us know. We always need other behind the scenes folks. 73, Charlie Sufana AJ9N One of the ARISS mentors ARISS mentor for Cache County In a message dated 2023-02-05 09:18:17 Eastern Standard Time, amsat-bb(a)amsat.org writes: Loren, I have to run but I will give you a complete explanation when I get back home. 73,Charlie AJ9NARISS Mentor for Cache County Sent from my T-Mobile 4G LTE Device -------- Original message --------From: "Loren M.

As time allows, students will ask these questions: 1. What is your biggest, personal goal in relation to space? 2. What keeps you pushing your limits when you are struggling to find motivation? 3. Was there a specific book, movie, or show that inspired you to become an astronaut? 4. How excited do you feel about the Artemis program and its upcoming missions? 5. How fast are you able to spin in a weightless environment? 6. Despite all your training and preparation for space, what is something about living in space you didn't expect? 7. What is your favorite part about the ARISS program? 8. What are you currently researching? 9. What is the part of your job you look most forward to? 10. What is the most fun or interesting experiment you have conducted in space? 11. Does sleeping in the sleeping bag trigger insomnia? 12. Do you ever get claustrophobic? 13. Which NASA project do you feel is the most important to us as human beings? 14. When did or what made you first realize you wanted to be an astronaut? 15. What's the most beautiful view you've seen from space? 16. How many repairs do you usually do to/on the space station daily? 17. If able to access music in space, what types do you usually listen to? 18. Is there a food you think is better in space than Earth? 19. Are plants grown aboard the ISS similar in size as the same plant grown on Earth? 20. What is your favorite 'trick' to do in a weightless environment?
