Having originally been launched into a 500km orbit, EO-88 has reduced in altitude rapidly over the past year due to the increased level of solar activity. Remarkably, some of the last frames of telemetry were captured as the 1U CubeSat passed over the South Western United States. The final 90 seconds show a rapid rise in temperature across all the satellites sub systems. The last frame of data was captured by David WB0IZO in New Mexico at 18:18:54 UTC showing the antenna temperatures operating about 40 degrees above normal. During the past 2 weeks, 86 stations have contributed EO-88 telemetry to the FUNcube Data Warehouse and this has given us the opportunity to study the behaviour of a functioning CubeSat as it makes its return from Space. Thank you all for your support. Having provided the last frame of data, David WB0IZO, wins the telemetry section of the AMSAT-UK re-entry competition and will receive a framed certificate of achievement. The prediction for the date and time of re-entry was very close with Paul N8HM predicting the 17th July and Larry N1MIW calculating the 21st. However, the winning entry was made by Thomas HB9SKA who correctly predicted the 18th July. Thomas also wins a framed certificate. RIP EO-88. GOODBYE AND THANKS FOR THE FUN! [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- URESAT-1 Update This is an update about our satellite URESAT-1, launched with SpaceX on June 12th (Transporter-8 mission from Vanderberg) and using Alba Orbital as our space broker. First of all, URESAT-1 is a small pocketQube 1.5P (8x5x5 cm), much smaller than a Cubesat. The satellite was expelled from the D-Orbit Orbital Transfer Vehicle (OTV) ION ten days after the launch, on June 22th at 12.10 UTC, along with MRC-100 and ROM-2 satellites. Soon after, using the OTV TLE available for pointing, signals from MRC-100 and ROM-2 were received but not ours... This made us think we again had a problem with the deployment of the antennas. Fortunately Daniel EA4GPZ could receive the URESAT-1 on June 26th using the ATA radio telescope at 22.03 UTC. The pattern of the transmissions matched and, using the IQs from the two antennas used, with two polarities, we could decodify telemetry, showing that the satellite was performing well with no resets or events. The battery was almost fully charged but the antennas were not deployed, as it was shown in the status packet received. We worked hard to improve the deployment system from our previous satellites but something hasn't gone well again. Satellite seems to be cold even in sunlight but we performed tests using temperatures as low as 20 C below zero so this should not be a problem... Doing a lot of analysis (after the ATA observation we found that our satellite was 20-30 seconds ahead of MRC-100) and with a lot of help from the Satnogs thread regarding that launch, we managed to conclude that our satellite should be NORAD object 56992. The team at Dwingeloo radio telescope on Netherlands has confirmed this with several observations these days https://network.satnogs.org/observations/7877553/ https://network.satnogs.org/observations/7881183/ https://network.satnogs.org/observations/7883687/ Using the IQs of these recordings (available here https://data.camras.nl/satnogs/) we have been able to decode new telemetry, CW and even a SSTV image from the satellite image bank. After more than three weeks in orbit the satellite is performing well and we hope that the antennas will deploy at some moment. The plan now is sending the satellite commands to try to deploy the antennas, although we are going to need a lot of power because the received signal without a proper antenna will be low. If you have a powerful station for transmitting on VHF and want to help us, please let me know. We want to thank Daniel EA4GPZ, the ATA radio telescope, PE0SAT, the Dwingeloo staff, especially Tammo Jan, and Satnogs staff for their kind help in identifying the URESAT and the reception of their signals. It has provided very valuable data on the status of the satellite. Decoded telemetry, CW and the SSTV image is available in our web (sorry, it is in spanish) and also in the Satnogs thread about the Transporter-8 mission: https://www.amsat-ea.org/ https://community.libre.space/t/spacex-f9-transporter-8-2023-06-12-21-35-ut… [ANS thanks Félix Páez, EA4GQS, AMSAT-EA President for the above information] +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ Need new satellite antennas?

During the event, the Columbus Module Repeater, transmitting at 437.800 MHz, will carry a message to be received by teachers attending the ARRL Teacher’s Institute class. The pass will be over the Mid-Atlantic / New England area with transmissions scheduled to begin at 20:05 UTC (16:05 ET) and ending at 20:20 UTC (16:20 ET). If necessary, a backup window will be 21:40 UTC (17:40 ET) to 21:55 UTC (17:55 ET). Radio enthusiasts are welcome to download the message and follow along with the event, but we ask that all hams please refrain from using the repeater for voice contacts during the event.

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 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.

The satellites were launched to the International Space Station on June 5 aboard the Japanese Experiment Module (JEM) Small Satellite Orbital Deployer-26, and were released from the ISS on July 19. The primary mission of Maya-5 and Maya-6 CubeSats is to provide digital message relay service to the amateur radio community by means of an APRS (Automatic Packet Reporting System) digipeater onboard. The APRS digipeater onboard the CubeSats will use 145.825 MHz for both receive and transmit. Another mission of the cubesats is to demonstrate a data/message store-and-forward (S&F) system in line with the Universal Amateur Radio Text and E-mail messaging. The CubeSats will also carry Commercial off-the-shelf (COTS) cameras which will take images of the participating countries from space for promotional and educational awareness.

The Sovereign Military Order of Malta is a separate DXCC entity. Satellite operations are expected on LEO satellites and QO-100. Details to follow (ANS thanks the 1A0C team for the above information) + The Sun's activity is defying forecasts and highlighting how difficult it is to predict the machinations of Earth's nearest star. Space weather can shorten the lifespans of satellites, cause radio blackouts and, in extreme solar storms, bring down power grids. Predictions from 2020 suggested the Sun would reach the peak of its 11-year solar cycle in 2025, and its intensity would be on par with the last cycle. But current observations show its activity could now peak as early as 2024. The current cycle is also on track to be more extreme, with more solar flares, sunspots and activity than the previous one, though not as big as others on record. The National Oceanic and Atmospheric Administration is planning to fly two new instruments to space that should help them keep an eye on the Sun in the coming years. A Sun-focused instrument is slated to launch on the GOES-U weather satellite next year, and another instrument will fly in 2025.

This Saturday, the 22nd, is the "Moon Day" space and space science themed annual event at the Frontiers of Flight Museum in Dallas Texas. I and several associates will be manning an Amateur Radio Satellite table there, showing off the cubesat simulator, the Fox Engineering model, and other space science tools. We will also, as usual, attempt to demonstrate Amateur Radio satellite communications by attempting to work some FM satellite passes during the span of the event. Unfortunately, during the span of the event, 1500Z to 2100Z, there will only be one really good AO-91 pass and however many of the TEVEL fleet that are activated. We will be co-located at the event next to the Dallas Amateur Radio Club. The Club will be activating their W5FC club callsign and they have given permission for us to use that call for satellites as wel since all of us working the AMSAT table, are also club members.l. So please give a listen, or even call for W5FC. Hopefully, we will have some observers in toe,. Making some contacts for them will be a really cool experience for them.

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 International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEAM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio.
