First off, the crew is only listening for one callsign that is being used for the school and have been told to ignore any other callsign. Second, the ISS is transmitting to earth on a public domain downlink frequency; but the uplink frequency from the school to the ISS is not published. Again, the crew will be listening only on the frequency that has been given to them to use. Also, if you try to call up on the public domain downlink frequency and happen to be near the school, then you probably just interfered with the school having a successful contact and disappointing a bunch of kids. The bottom line is please be courteous and let the kids have their fun day. They have been planning, working hard, and waiting for a very long time and we really don’t want to see them disappointed. Please use the crossband repeater when it is available. You just never know who might pop on. ####################################################################################################################################### Many times, a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication. You can always check https://live.ariss.org/ to see if a school is Livestreaming. ARISS YouTube Channel: ARISS - Amateur Radio on the ISS - YouTube. Here you will also find past contact videos. The crossband repeater continues to be active. If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. 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 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour 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 sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

Waiting on ARISS-RU to indicate if it was considered successful. (***) Proposed questions generated by the Pacific State University students: (***) 1. Приветствие и поздравление (ключевой момент) «Уважаемый экипаж! От имени коллектива Филиала РТРС «Дальневосточный РЦ» поздравляем вас с работой на орбите. В этом году Российская телевизионная и радиовещательная сеть (РТРС) отмечает 25 лет. Что бы вы хотели пожелать нашему коллективу и всем, кто обеспечивает связь для миллионов людей на Земле?» 2. О жизни в эфире: «Наша главная задача – чтобы теле- и радиосигнал доходил до людей даже в самых отдаленных уголках Дальнего Востока. А как устроена радиосвязь на МКС?» 3. О простоте и надежности сигнала: «Люди на Земле привыкли включать радио за завтраком. А есть ли у вас на станции традиция слушать радио или смотреть новости с Земли в определённое время?» 4. О географии (связь с Дальним Востоком): При прохождении трассы полёта МКС над Хабаровском наблюдаются ли изменения в параметрах радиоканала связи с ЦУПом? (например, уровень сигнала, соотношения сигнал/шум, частота срывов связи) 5. О технике и «зонах молчания»: «Наши инженеры часто работают на вышках в сложных погодных условиях. А с какими сложностями вы сталкиваетесь на орбите?» 6. О будущем связи: «С момента запуска первого спутника связь шагнула далеко вперед. Как вы думаете, какой канал связи через 25 лет (к следующему юбилею РТРС) покажется нам таким же обычным, как сегодняшнее радио, лазерная связь, квантовая или что-то ещё?» 7. О мотивации для специалистов: «Молодые специалисты нашего филиала в области радиотехники, стремятся к максимальной стабильности параметров сигнала, формируемого нашим оборудованием. Что бы Вы могли рекомендовать молодым кадрам, начинающим профессиональную деятельность в сфере связи и радиотехники на территории Дальнего Востока?» 8. Изменились ли ваши представления о Земле и человечестве после того, как вы увидели нашу планету из космоса? 9. Как вы считаете, какие качества характера и навыки особенно важны для будущих космонавтов при совершении межпланетных перелетов? 10. Какие научные эксперименты, проводимые на МКС, по вашему мнению, смогут принести наибольшую пользу для людей на Земле в ближайшем будущем? 11. Какие, в настоящее время, технологии проходят апробацию на МКС, использование которых предполагается при межпланетных перелетах? 1. Greeting and congratulations (key point) "Dear crew! On behalf of the staff of the RTRS Branch "Far Eastern RC" Congratulations on your work in orbit. This year, the Russian Television and Radio Broadcasting Network (RTRS) celebrates its 25th anniversary. What would you like to wish our team and everyone who provides communication for millions of people on Earth?" 2. About life on the air: "Our main task is to ensure that the television and radio signal reaches people even in the most remote corners of the Far East. And how is radio communication on the ISS arranged?" 3. About the simplicity and reliability of the signal: "People on Earth are used to turning on the radio at breakfast. Do you have a tradition at the station listen to the radio or watch the news from Earth at a certain time?" 4. About geography (connection with the Far East): When passing the ISS flight route over Khabarovsk, are there any changes in the parameters of the radio communication channel with the MCC? (e.g., signal strength, signal-to-noise ratio, failure rate) 5. About technology and "zones of silence": "Our engineers often work on towers in difficult weather conditions. And with what difficulties do you face in orbit?" 6. On the future of connectivity: "Since the launch of the first satellite, communications have stepped far forward. What do you think the communication channel in 25 years (by the next anniversary of RTRS) will seem to us as ordinary as today's radio, laser communication, quantum or something else?" 7. On motivation for specialists: "Young specialists of our branch in the field of radio engineering strive for maximum stability of the signal parameters generated by our equipment. What would you recommend to young personnel who are starting their professional career in the field of communications and radio engineering in the Far East?" 8.
