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 2024-08-12 20:00 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 2024-08-12 20:00 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.

The old Mirage B1016 I have sometimes used on Mode J attenuates 70cm signals. The amp’s antenna port is permanently connected to a low pass filter.

Hi John, Science mode is enabled when we send image data. You can see that in FoxTelem because you will receive data on the MESAT Science tab. If that data is valid image packets then an image is built on the Multispectral Camera Tab. Each image captured is actually 4 images or channels and will become 4 separate images in FoxTelem. Each taken with a different filter. A copy of the images is also saved as a bitmap in the FoxTelem data directory in an images sub folder. There is a slightly updated version of FoxTelem on my website, in the development downloads, which indicates how many bytes you have received for each block in the image. Download version 1.12z5 (not version 1.13 which does not have this feature yet): https://www.g0kla.com/foxtelem/ With that said, nothing in space is easy and so far we have only retrieved some test data that was loaded before launch, from Image 1 Channel 0. But we are optimistic that image data is coming. Our current test is over and the spacecraft is back in SAFE mode where it will rest for about 3 days. We hope to start some science operations again after that. If you are curious about the data, then you can always download the full set collected by everyone from the server. The FoxTelem manual explains how to setup a second copy of FoxTelem with a different data folder. You can then pull the server data down into that copy with File > Fetch Server Data. There you will see the partially downloaded test data. If you are good at sleuthing through data you can see the magnetorquers activate when we sent commands to stabilize the spacecraft for image capture.

The request was fully consistent with the QCWA’s Mission Statement which reads in part “to promote interest in Amateur Radio communications and the advancement of the electronic art” especially among boys and girls essential to keep Amateur Radio and AMSAT’s ranks filled for the future growth of the hobby. [cid:image003.png@01DAEB46.A2C5EFD0] In response to its proposal, the QCWA generously awarded $2,500 to AMSAT on June 4, 2024 for its youth and educational programs. Building on Dr. Alan Johnston, KU2Y’s ground breaking CubeSat Simulator, the QCWA contribution will help bring actual “CubeSatSims” to more classrooms, enhance instructional materials and to help build a network of online simulators to bring the benefits of this exciting resource directly to youth, their families and to educational resources of all types. A portion of this generous gift will also be used to further the curriculum of AMSAT’s “KidzSat” program, designed to spark youth’s interest in space communications with its theme, “Satellites in Space for a Better Life Here on Earth.” For older youth the “BuzzSat” program uses Amateur Radio as the laboratory for hands-on experiences with telemetry, control and communications. In recognition of the QCWA’s contribution to AMSAT programs, the QCWA was inducted into the AMSAT 2024 President’s Club at the Platinum level. Upon receiving news of the award, Karnauskas remarked, “Thanks to the vision of generous benefactors such as the QCWA, AMSAT is better equipped to help bring more youth into the exciting world of satellite communications and the benefits it can bring to mankind – Satellites in Space for a Better Life on Earth!” [ANS thanks AMSAT for the above information.] ________________________________ Need new satellite antennas?

The module was programmed to transmit FT-8, which is, as far as the project managers know, the first time that this modulation has been used from space, as well as SSTV. Although its reception seemed impossible, a station located in Delft, the Netherlands, confirmed the reception and decoding of FT-8, as well as the reception of SSTV in orbits 3 and 4 that the stage carried out over Europe. [cid:image005.jpg@01DAEB46.A2C5EFD0] The station, belonging to the Von Storch Engineering company, has provided the IQ files of the recordings for analysis by AMSAT-EA. Although the stage was expected to fall into the sea, this did not happen and the GENESIS-A module remains in orbit with the stage. ESA was asked about the availability of power in the launcher stage and about the possibility of restarting the module, but the battery pack that powered YPSAT and the GENESIS-A module was completely depleted, so there is no real possibility of restarting it.

CubeSats are a class of small spacecraft called nanosatellites. The initiative provides space access to U.S. educational institutions, certain non-profit organizations, and informal educational institutions such as museums and science centers, as well as NASA centers focused on workforce development, including the agency’s Jet Propulsion Laboratory in southern California. It also encourages participation by minority serving institutions. “Working with CubeSats is a way to get students interested in launching a career in the space industry,” said Jeanie Hall, CSLI program executive at NASA Headquarters in Washington. “NASA reviews applications for CubeSat missions every year and selects projects with an educational component that also can benefit the agency in better understanding education, science, exploration, and technology.” Applicants must submit proposals by 5 p.m. EST, Nov. 15. NASA expects to make selections by March 14, 2025, for flight opportunities in 2026-2029, although selection does not guarantee a launch opportunity. Applicants are responsible for funding the development of the small satellites. Selected CubeSats get assigned a launch and deployment directly from a rocket or to low Earth orbit from the International Space Station. Once accepted, NASA mission managers act as advisors to the CubeSat team, ensuring technical, safety, and regulatory requirements are satisfied before launch. Those selected will strengthen their skills in hardware design and development and build knowledge in operating the CubeSats. Eight CubeSat missions recently shared a ride to space on Firefly Aerospace’s Alpha rocket that launched on July 3 from Vandenberg Space Force Base in California. One mission is CatSat, built by students at the University of Arizona, which is testing a deployable antenna attached to a Mylar balloon. Another is KUbeSat-1, built by the University of Kansas, is testing a new method of measuring the cosmic rays that hit the Earth. This launch also was notable for two CSLI ‘first’ milestones. The KUbeSat-1 and another called MESAT-1 were the first CSLI missions from the states of Kansas and Maine respectively. Four CubeSats also went to the space station as cargo in a SpaceX Dragon capsule on March 21 aboard a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida as part of the agency’s SpaceX 30th commercial resupply mission. Once aboard the space station, astronauts deployed the small missions into various orbits to demonstrate and mature technologies meant to improve solar power generation, detect gamma ray bursts, determine crop water usage, and measure root-zone soil and snowpack moisture levels. CubeSats are a class of spacecraft sized in multiples of a standardized unit called a “U.” A 1-Unit (1U) CubeSat is about 10 x 10 x 11 cm in size (3.9 x 3.9 x 4.5 inches). They are small enough to fit in the palm of your hand and can be stacked together to form a slightly larger, more capable spacecraft. A 3U CubeSat is three times the size of a 1U, a 6U is six times the size. NASA has selected CubeSat missions from 45 states, Washington, and Puerto Rico, and launched about 160 CubeSats since inception. The CubeSat Launch Initiative is managed by NASA’s Launch Services Program based at NASA’s Kennedy Space Center in Florida.

[ANS thanks AMSAT for the above information.] A Chinese Long March 6A rocket broke apart in low-Earth orbit and formed a debris field with hundreds of pieces, confirmed by U.S. Space Command. “USSPACECOM has observed no immediate threats and continues to conduct routine conjunction assessments to support the safety and sustainability of the space domain,” a U.S. Space Command spokesperson said. NASA public affairs officer Rob Margetta said there was no immediate threat to the International Space Station. Satellite monitoring company LeoLabs estimated there were at least 700 fragments created by the rocket’s break-up. While there’s no immediate danger, it’s possible that the fragments could eventually descend to where the space station and SpaceX’s Starlink satellites are located. Slingshot Aerospace said debris from the rocket poses “a significant hazard to LEO [low-Earth orbit] constellations below 800 km altitude.” More information at https://tinyurl.com/ANS-224-Debris.
