Help Support GOLF and Fox Plus [https://www.amsat.org/wordpress/wp-content/uploads/2024/01/2024-Coin-Both_5…] Join the AMSAT President's Club today and help Keep Amateur Radio in Space! https://www.amsat.org/join-the-amsat-presidents-club/ ________________________________ SpaceX Falcon Heavy Successfully Launches GOES-U Satellite On June 25, a SpaceX Falcon Heavy rocket successfully lifted off from Kennedy Space Center's Launch Complex 39A at 5:26 p.m. Eastern, carrying the GOES-U weather satellite, the final spacecraft in a series of geostationary weather satellites. This launch featured several notable firsts, overcoming previous weather forecasts that had predicted only a 30% chance of favorable conditions. The GOES-U satellite, successfully deployed from the Falcon Heavy's second stage four and a half hours after liftoff, after the stage completed a sequence of three burns to place the satellite into a geostationary transfer orbit. Built by Lockheed Martin for the National Oceanic and Atmospheric Administration (NOAA), GOES-U will be renamed GOES-19 upon reaching geostationary orbit. After on-orbit commissioning, it will be positioned at 75 degrees east in geostationary orbit, taking over from GOES-16 as the operational GOES-East satellite. GOES-U carries a suite of earth and space science instruments similar to its predecessors but includes the new Compact Coronagraph (CCOR) instrument for solar observation. CCOR will monitor the solar corona for flares and coronal mass ejections, a crucial function for understanding space weather. This role was previously filled by the nearly 30-year-old Solar and Heliospheric Observatory spacecraft. [https://www.amsat.org/wordpress/wp-content/uploads/2024/06/GOES-U-SpaceX-Fa…]<https://url.us.m.mimecastprotect.com/s/SyPQCkRPn8hJOAwLsyAsIC?domain=amsat.…> GOES-U lifts off from NASA's Kennedy Space Center Launch Complex 39A on June 25th, 2024. [Credit: SpaceX] The GOES-R series, which began with a launch in 2016, has significantly improved weather forecasting. Ken Graham, director of the National Weather Service, stated at a pre-launch briefing, "The GOES-R series of satellites, it's been a gamechanger for us." The satellites have enabled new and improved forecasts, warnings, and services that help save lives and protect property. Among the enhancements in the GOES-R series is a lightning mapper. Pam Sullivan, director of the GOES-R program at NOAA, highlighted its impact, saying it allows meteorologists to better understand storm severity and issue more accurate warnings. "The main thing I hear from forecasters is that they have more confidence in a forecast," she noted. NOAA is already planning the next generation of geostationary weather satellites, called GeoXO, set to begin launching in 2032. Contracts have been awarded to Lockheed Martin for satellite construction and BAE Systems for sounder and ocean color instruments. Steve Volz, assistant administrator of NOAA's Satellite and Information Service, described GOES-U as "the bridge that connects today's geostationary satellite technology with the technology of tomorrow." [https://www.amsat.org/wordpress/wp-content/uploads/2024/06/NOAA-GOES-U-Sate…]<https://url.us.m.mimecastprotect.com/s/WGUSClYPoxiY2mM9iDlGrJ?domain=amsat.…> NOAA's GOES-U satellite undergoing testing by Lockheed Martin in Littleton, Colorado. [Credit: Lockheed Martin] The launch was marked by the synchronized landings of the two Falcon Heavy side boosters at Landing Zones 1 and 2 at Cape Canaveral Space Force Station. This mission was also the first time NOAA launched a GOES weather satellite on a SpaceX rocket. The three previous GOES-R satellites launched on Atlas 5 rockets from United Launch Alliance (ULA), but SpaceX was awarded the $152.5 million contract for the GOES-U launch in September 2021 after ULA withdrew due to a lack of available Atlas rockets. The Falcon Heavy's additional performance is a key advantage. Julianna Scheiman, director of NASA science missions at SpaceX, explained that the rocket's capability allows for a significant delta V reduction, meaning the spacecraft requires less energy to reach its final orbit. This efficiency translates into fuel savings and extended operational life for GOES-U, which has a design specification of 15 years. "With the added capability Falcon Heavy is giving us, we expect to be at 20-plus years of fuel life," said NOAA's Sullivan. The GOES-U launch marked the 10th overall for the Falcon Heavy and the second contracted by NASA, following the Psyche asteroid mission in October 2023. Another Falcon Heavy is set to launch NASA's Europa Clipper mission this October, continuing SpaceX's role in advancing space exploration and weather monitoring capabilities.

This rehearsal involved loading 180 tons of supercooled propellant into the rocket, cooling its components to cryogenic temperatures, and rolling back the mobile gantry. ESA's Guy Pilchen highlighted that this rehearsal allowed teams to refine launch operations using the actual flight hardware and software. Following fueling, the rocket underwent final preparations for its upcoming launch, expected to confirm its date after data analysis. With payloads ranging from Earth observation to scientific experiments, Ariane 6 aims to secure Europe's independent access to space and advance space exploration. (ANS thanks the European Space Agency for the above information) + China's Chang'e 6 probe has returned to Earth on June 25, 2024, with the first-ever samples from the far side of the moon, landing in Inner Mongolia on Tuesday. The successful mission marks a global milestone, with the samples expected to include 2.5 million-year-old volcanic rock that could shed light on the geological differences between the moon's near and far sides. The probe landed in the moon's South Pole-Aitken Basin, providing samples from various geological layers. This mission is part of China's growing space rivalry with the U.S. and other nations, aiming to establish China as a technological power. The journey began on May 3 and lasted 53 days, involving drilling into the core and collecting surface rocks. China plans to share the samples with international scientists, hoping to answer fundamental questions about lunar geology and the solar system's early days. (ANS thanks Huizhong Wu, Associated Press, for the above information) + NASA called off a planned spacewalk on June 24 due to a malfunction in astronaut Tracy Dyson's spacesuit. Dyson and her crewmate Mike Barratt were preparing to exit the International Space Station to conduct maintenance when a water leak was detected in Dyson's suit cooling unit. This unit is crucial for maintaining a comfortable temperature during spacewalks. The leak occurred just after the suits were switched to battery power, prompting NASA to abort the mission. Although Dyson reported feeling a bit warm and expressed concerns about potential water damage to electrical connectors, both astronauts were safe throughout the incident. This cancellation follows a similar recent setback on June 13, involving a spacesuit issue, and it raises questions about the potential impact on the return schedule of Boeing's Starliner capsule. (ANS thanks Jackie Wattles, CNN, for the above information) + NASA astronauts Suni Williams and Butch Wilmore, who flew Boeing's Starliner capsule to the International Space Station (ISS), have had their return to Earth delayed multiple times due to issues with the spacecraft. Originally planned to stay for about a week, their mission has been extended indefinitely as NASA and Boeing investigate a slow helium leak and malfunctioning thrusters discovered after reaching orbit. The latest delay was announced last week, with no new return date set yet. Despite these issues, the astronauts are assisting with tasks and conducting tests on the ISS, where they are accommodated with sufficient supplies. NASA is taking a cautious approach, allowing data to drive decisions about managing the leaks and thruster performance. This mission aims to certify the Starliner for future routine flights, similar to SpaceX's Crew Dragon service for NASA.

The amateur radio volunteer team at the ground station will use the call sign VK6MJ, to establish and maintain the ISS connection. The ARISS radio contact is scheduled for July 1, 2024 at 1:02 pm WEST (Morocco) (12:02 UTC, 8:02 am EDT, 7:02 am CDT, 6:02 am MDT, 5:02 am PDT). *_______________________________* As time allows, students will ask these questions: 1. If you had the choice, which planet would you choose to discover? 2. If there's a damage or a problem on the ISS that can't be fixed, what would you do in that case? 3. If you could send a message back to yourself on Earth before you embarked on this mission, what would you say to yourself? 4. How does NASA benefit from software and computer systems to support astronauts during missions? 5. Before going to space what preparations should every astronaut make to cope with the Space Environment? 6. Are there any effects on the astronauts’ health after being in space for a long time? 7. How did you decide to become an astronaut? 8. Does time work differently in Space, and how do astronauts keep track of their ages? 9. What is the last thing you did before going into space? 10. What advice would you give to someone passionate about astronomy and wants to make a career out of it? 11. Could financial experts and space agencies like NASA team up to manage resources better for space missions? 12. What is the nature of dark matter and dark energy, and how do they influence the universe’s structure and expansion? 13. Is there any evidence for the existence of other universes beyond our own, and what do the latest Nasa discoveries say about the multiverse theory? 14. Astronauts often come from different academic backgrounds, so what did you study to become an astronaut? 15. What is the recent experiment you conducted in space that may have an impact on scientific research or daily life on Earth? 16. How does AI contribute to the success of space missions? 17. How do you manage daily tasks in a zero-gravity environment? 18. How does a SAFER work if you become detached from the ISS during an EVA? 19. What are the physical conditions and requirements that astronauts must meet? 20. What's first thing you want to do after landing on Earth and coming back home? *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 ISS. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. 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.

Upcoming ARISS Contact Schedule as of 2024-06-28 15:00 UTC
by aj9n＠aol.com 28 Jun '24

28 Jun '24

Upcoming ARISS Contact Schedule as of 2024-06-28 15:00 UTC Quick list of scheduled contacts and events: Moroccan School of Engineering Sciences, Casablanca, Morocco, telebridge via VK6MJ The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Jeanette Epps KF5QNU The ARISS mentor is IN3GHZ Contact is go for: Mon 2024-07-01 12:02:01 UTC 60 deg St. Luke’s College, Buenos Aires, Argentina, direct via LU4AA The ISS callsign is presently scheduled to be NA1SS The downlink frequency is presently scheduled to be 145.800 MHz The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The scheduled crewmember is Matthew Dominick KCØTOR (***) The ARISS mentor is VE6JBJ Contact is go for: Tue 2024-07-02 15:30:42 UTC 52 deg (***) Watch for Livestreaming via their Instagram accounts: The school: @stlukes.college Radio Club Argentino: @rca_sociedad_nacional 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. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-06-28 15:00 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 The successful school list has been updated as of 2024-06-27 18:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.

Re: Yaesu G-5500 issue FIXED
by jeff griffin 27 Jun '24

27 Jun '24

The G5500 control box is now working. I compared the bad transformer with the good one I had on hand. It was pretty obvious that the bad transformer was defective .8 ohms across the primary vs the good ones 8.9 ohms. Soldered the primary side into the assumed working rotor box, wired the primary in and checked the 26v and 16v secondary's . All's good. Soldered them in and powered up the rotor all good. I then connected the AZ and EL cables and all was working. I hooked it up to the LVBTracker box, and found the setup is in need of a calibration. So as we type I'm operating on IO-117 using the controls on the box to track the satand just worked an LU. I decided to swap out the box I was working on as I wasn't sure what other mods were done to it besides the 12v VR that I assume was done for a long cable run. So now I have a good working box, and a spare metal box, and maybe a spare pair of working meters. Life is again good in KB2M land... 73 Jeff kb2m

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. 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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2024-06-27 18:00 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 The successful school list has been updated as of 2024-06-27 18:00 UTC. (***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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.

Hi Jeff,Have you looked at whether amps Q1003 and Q1004 are blown and maybe giving directly 6 or 12V (whatever it is supposed to be) to the meters? They might be shorted somehow to give full voltage all the time to the meters.What happens if you try to adjust the pots labeled VR0001 and VR0002? The meters should a change as you adjust them.Good luck,Charlie AJ9NSent from my T-Mobile 5G Device -------- Original message --------From: graham shirville via AMSAT-BB <amsat-bb(a)amsat.org> Date: 6/26/24 5:01 PM (GMT-05:00) To: 'jeff griffin' <kb2mjeff(a)att.net>, amsat-bb(a)amsat.org Subject: [AMSAT-BB] Re: Yaesu G-5500 issue Hi Jeff, Well I was assuming that it is the older 5500 model which has an AC motor - this has an instruction manual which shows a 6V regulator (top of circuit diagram).https://www.yaesu.com/downloadFile.cfm?FileID=8814&FileCatID=155&F… Maybe you have the 5500DC model for which they don’t seem to publish the circuit diagram?

I removed the LM7812 and put in a LM7806. I now have 6v between pin1 and pin3. I also still have full scale on the meters. I tried all the things that were suggested. including the OHM test between wire on pin1 and wire on pin3 500 ohms , and 250 or so between wop2 to wop3 and wop1. SO it looks like the rotor is ok, it still rotates in AZ and EL. I'm going to leave the 6v VR in as my cable runs are only about 30 feet. What to do next. I have two broken G-5500 control boxes here, the one I'm working on, and one with a bad transformer(it blows fuse when turned on). I also have half a working spare rotor, I forget if the AZ or EL is broke. If I send the box into Yaesu to fix, it will with the shipping probably be at least $200. I called Yaesu and they have new G-5500 control boxes for $380. I'm running out of stuff to try with this issue, and there isn't a lot of info to try and dig in any deeper. If I don't come up with anything I think I'm just going to buy a new control box, either the Yaesu or possibly another Green Heron FT-21azel.

Looking at the schematic for the 5500 there are 2 op amps that drive the meters. That would be my guess seeing how there is not much more than that. I believe someone else may have mentioned this. Could be a 2 dollar fix? On Wednesday, June 26, 2024 at 04:43:30 PM EDT, jeff griffin via AMSAT-BB <amsat-bb(a)amsat.org> wrote: Ok. I removed the LM7812 and put in a LM7806.

Hi Jeff, Well I was assuming that it is the older 5500 model which has an AC motor - this has an instruction manual which shows a 6V regulator (top of circuit diagram). https://www.yaesu.com/downloadFile.cfm?FileID=8814 <https://www.yaesu.com/downloadFile.cfm?FileID=8814&FileCatID=155&FileName=G…> &FileCatID=155&FileName=G-5500_IM_ENG_E12901004.pdf&FileContentType=application%2Fpdf Maybe you have the 5500DC model for which they don’t seem to publish the circuit diagram?

I would guess that they supplied extra voltage for setups with long cable runs to make sure you could get full scale. Then the adjust it down with the pots.

I have power wires to a preamp running through a PVC conduit and have had mice get in and chew them through. So that is one guess--mice on the potentiometer power. Another possibility is that there was a nearby lightning strike over the winter and it opened up your surge protector. Or if you don't have one, maybe that blew the S.A.T. 73, Burns WB1FJ On Sun, Jun 23, 2024 at 11:33 AM mikflathead--- via AMSAT-BB < amsat-bb(a)amsat.org> wrote: > Do you have any angry squirrels? > > On Sunday, June 23, 2024 at 10:51:42 AM EDT, Jim McCullers via AMSAT-BB < > amsat-bb(a)amsat.org> wrote: > > > Jeff, > > > > Remove the wires connected to terminal positions 1, 2, and three on both > the Al and Ez connectors on the back of the G-5500. > > Make certain you label them or take a photo for reinstallation. > > > > With the G-5500 powered on, measure from terminal 1 to terminal 3 on each > connector using volt meter. > > You should read 6 volts +/- a fraction. > > Both Al and Ez are powered by the same circuit.

Jeff, I am suspicious that when that regulator failed, it damaged the op-amps that drive the meters. Consider probing around from the rotor connections through that meter drive circuitry to see where the signal levels stop making sense. Fortunately it looks like replacement op amps are cheap, I saw what look like viable replacements at Digi-Key for $0.54. de KM1P Joe

ARISS News Release No. 24-32
by David H Jordan 24 Jun '24

24 Jun '24

*ARISS News Release No.24-32* *Dave Jordan, AA4KN * *ARISS PR* *aa4kn(a)amsat.org <aa4kn(a)amsat.org>* *FOR IMMEDIATE RELEASE* *ARISS Contact is Scheduled with Students at * *The Educational Complex Nuestra Señora de Fátima No 1139 and No 8119, Pérez, Argentina* June 24, 2024—Amateur Radio on the International Space Station (ARISS) has received schedule confirmation for an ARISS radio contact between an astronaut aboard the International Space Station (ISS) and students at the Complejo Educativo Nuestra Señora de Fátima located in Pérez, Argentina. ARISS conducts 60-100 of these special amateur radio contacts each year between students around the globe and crew members with ham radio licenses aboard the ISS. The Educational Complex Nuestra Señora de Fátima, (comprised of schools No. 1139 and No. 8119) is a comprehensive educational institution covering primary and secondary levels. The school fosters students’ interest in and vocational development in the sciences by implementing a series of activities, such as their annual workshops on physical and chemical phenomena. These workshops promote discovery through experimentation and allows students to explore and understand the fundamental principles that govern these two sciences. Among the topics covered for the 6th grade program are the scientific method, experiments on energy transfer, waves, sound and light, telescopes, and setting up a weather station. The 7th Grade program covers the solar system, Earth-Moon-Sun system, Moon landings, the ISS and life in space, the importance of caring for the Earth, celestial maps and constellations, stars, star clusters, nebulae, and galaxies. The schools collaborate with a group of amateur radio operators and astronomy enthusiasts, which allows student access to expert and specialized guidance. This will be a telebridge Contact via Amateur Radio allowing students to ask their questions of astronaut Jeanette Epps, amateur radio call sign KF5QNU. The downlink frequency for this contact is 145.800 MHz and may be heard by listeners that are within the ISS-footprint that also encompasses the telebridge station. The ARISS amateur radio ground station (telebridge station) for this contact is in Meadow Spring, Australia. The amateur radio volunteer team at the ground station will use the callsign VK6MJ, to establish and maintain the ISS connection. The ARISS radio contact is scheduled for June 27, 2024 at 10:38 am ART (Pérez, Argentina) (13:38 UTC, 9:38 am EDT, 8:38 am CDT, 7:38 am MDT, 6:38 am PDT). *_______________________________* As time allows, students will ask these questions: 1. What can you see through a window that doesn’t face Earth? 2. How do astronauts readapt to living on Earth after returning from space? 3. What happens if an astronaut is left floating in space without anything to hold onto? 4. How do you cut your hair? 5. Are there any smells in space? What does space smell like? 6. What’s the first thing you would like to do when you return to the Earth? 7. What do you do if an astronaut gets sick? Are illnesses different in space? 8. What happens if there is an accident? 9. How does being in space affect sleep? 10. What is the most amazing thing you can do in space? 11. What inspired you to become an astronaut? 12. What’s the most beautiful thing astronauts have seen on the ISS? 13. Does the Sun affect you when you go into space? How? 14. Can astronauts cry in space? Can your tears drop? 15. How do astronauts film outside the ISS? 16. How has being an astronaut affected personal relationships? 17. How does it feel to be in space for 6 months or more? 18. How did you prepare to become an astronaut? *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 ISS. In the United States, sponsors are the American Radio Relay League (ARRL), Amateur Radio Digital Communications (ARDC), Radio Amateur Satellite Corporation (AMSAT), NASA’s Space Communications and Navigation program (SCaN) and the ISS National Lab—Space Station Explorers. 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.
