The astronauts, John Shoffner, KO4MJC and Woody Hoburg, KB3HTZ, provided an opportunity for amateur radio operators to establish contact with the orbiting space station. The Amateur Radio on the ISS (ARISS) program facilitated these voice contacts, allowing radio operators to communicate with the astronauts onboard the ISS. As the news spread on social media, amateur radio operators shared their excitement about making successful contacts with the astronauts. Hams from different parts of the world, including Europe, the United States, and the United Kingdom, shared their experiences of communicating with the ISS crew on Twitter. The astronauts were actively seeking information about the location of each station, showing a keen interest in the diverse range of contacts they were making. The ARISS program encourages participants to submit QSL cards to commemorate their successful contacts. These cards serve as proof of communication with the International Space Station. The ARISS website provides information on how to send in QSL cards and further details about the program. The QSL contacts are regional so find the proper one at: https://ariss.org/qsl-cards.html For many radio operators, making contact with the International Space Station is a memorable experience. The ability to communicate with astronauts orbiting the Earth, even if only for a brief moment, is a testament to the power of amateur radio and its ability to connect people across vast distances. As the ARISS program continues to facilitate these voice contacts, space and amateur radio enthusiasts eagerly await further opportunities to establish communication with the astronauts onboard the ISS. The chance to exchange greetings and information with those who reside in space remains a unique experience that showcases the wonders of technology and human ingenuity. Operators interested in attempting a contact with the ISS crew, should set the downlink frequency to 437.800 MHz FM and listen for activity. The uplink frequency is 145.990 MHz FM with a PL tone of 67 Hz. The ARISS website and the AMSAT status page provide information on the ISS crew's radio activities. See https://www.ariss.org/contact-the-iss.html for details.

On May 30, 2023, a total of seventeen people from five different countries were in Earth orbit. The population in orbit skyrocketed with the launch of China's Shenzhou 16 mission, which took place on May 29 at 9:31 p.m. EDT. This three-person mission propelled the overall count to a new record. Previously, the record stood at fourteen people, achieved during the privately funded Inspiration4 mission in September 2021. The current count consists of four crews representing various space agencies and private ventures. The first crew, Shenzhou 16, consists of Chinese taikonauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao, who have joined the astronauts already aboard China's Tiangong space station. This mission contributes three members to the total count. The second crew, Shenzhou 15, consists of Fei Junlong, Deng Qingming, and Zhang Lu. They have been residing aboard the Tiangong space station since November 2022 and are expected to return to Earth in early June. Their presence adds another three individuals to the record-breaking count. The third crew, Expedition 69, comprises seven members from different countries. It includes cosmonauts Sergey Prokopyev, Dmitry Petelin, and Andrey Fedyaev from Russia's Roscosmos, as well as astronauts Frank Rubio, Stephen Bowen, KI5BKB, and Warren "Woody" Hoburg, KB3HTZ, from NASA. Emirati astronaut Sultan AlNeyadi, KI5VTV, of the United Arab Emirates (UAE) also joins them. These individuals are currently on the International Space Station (ISS), contributing significantly to the total population in orbit. The fourth crew, Axiom-2, is composed of Axiom Space astronaut Peggy Whitson, private astronaut John Shoffner, KO4MJC, and Saudi Arabian astronauts Ali AlQarni, 7Z1AJ, and Rayyanah Barnawi, 7Z1RB. They departed the ISS aboard SpaceX's Crew Dragon "Freedom" on May 30. The Axiom-2 crew splashed down off the Florida panhandle near Panama City around 11 p.m. on May 30, reducing the count to thirteen people. Interestingly, the current record-breaking count coincides with another milestone. Barnawi, a member of the Ax-2 mission, became the 600th person to enter Earth orbit. She also holds the distinction of being the first Saudi woman in space, as she launched alongside her crew on May 21. Although the record stands at seventeen people in Earth orbit, it's worth noting that a recent record for the most people in space (not just in Earth orbit) was set briefly. For approximately five minutes, a total of twenty individuals were off the planet. This record occurred when the six members of Virgin Galactic's Unity 25 SpaceShipTwo crew embarked on a suborbital spaceflight, coinciding with three Chinese taikonauts residing aboard Tiangong and eleven astronauts, cosmonauts, and spaceflight participants aboard the International Space Station. The previous record for the most people in space simultaneously was set during Blue Origin's New Shepard NS-19 suborbital flight on December 11, 2021, when there were briefly nineteen individuals off Earth. Since the year 2000, there has been an unbroken presence of humans in space, starting with the first crew to inhabit the International Space Station. China's completion of its three-module Tiangong space station last year marks another significant milestone. The Shenzhou 16 crew represents the station's fifth contingent since 2021.

The technical problems, which escaped detection for years, dealt another setback for Boeing’s Starliner program, already running years behind schedule after a series of issues with software, valves, and other parts of the spacecraft. NASA wants Boeing’s Starliner to come online as a second U.S. crew transportation provider for the space station. Russia’s Soyuz spacecraft, which was the sole vehicle to carry crews to the space station for nine years, is currently NASA’s backup if SpaceX’s Falcon 9 rocket or Crew Dragon spacecraft suffer significant delays or failures. NASA astronauts Butch Wilmore and Suni Williams, KD5PLB, were in the final stages of training for launch on the first Starliner crew mission, called the Crew Flight Test, as soon as July 21. They were slated to lift off from Cape Canaveral on a United Launch Alliance Atlas 5 rocket and fly to the space station on the Starliner spacecraft for a test flight lasting about one week, then return to Earth for a parachute-assisted landing in New Mexico. That would have paved the way for Boeing to start launching regular NASA crew rotation flights to the space station on a schedule of about once per year beginning in 2024. Boeing and NASA officials did not provide an estimate for when engineers might resolve the newest technical problems on the Starliner spacecraft.

The MRC-100 is the successor to the SMOG-1 CubeSat which was launched in March 2021. The satellite is named to honoring the 100th year anniversary of the HA5MRC Ham Radio Club at the Budapest University of Technology. To help with decoding the Telemetry on the CubeSat, an RTL-SDR based telemetry receiver was created and an installation script for Raspberry Pi's and Linux PC's which installs OpenWebRX along with the satellite receiver software. The satellite should be receivable with a simple satellite antenna, such as a handheld Yagi, Turnstile, Dipole or quadrifilar-helix antenna. It will be transmitting telemetry at 436.720 MHz. If you have a dish and tracking equipment for it, there is also a high speed downlink at 2267.5 MHz.

In 2021, the agency selected Starship ? the biggest and most powerful rocket ever built ? to be the first crewed lunar lander for its Artemis program of moon exploration. Starship will put astronauts down near the ice-rich lunar south pole on the Artemis 3 mission, in humanity's first return to the moon since the Apollo program ended in 1972. Artemis 3 is currently targeted to lift off in December 2025, but it's unlikely Starship will be able to meet that timeline, NASA officials said.

The satellite is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities. The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV, which will orbit the Earth for several days before deploying URESAT-1, along with other satellites. One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last movement made, and whether the next move belongs to the players or the satellite. The specified frequencies for communication with URESAT-1 are as follows: for uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For downlink transmissions, the frequency is set at 436.888 MHz, and modes include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon with the callsign AO4URE. To provide further information regarding URESAT-1's transmissions, the AMSAT-EA organization has made available a comprehensive document that can be accessed at the following link: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmissions+description.pdf For those interested in decoding the telemetry, a Linux x86/ARM decoder is available for download at the following link: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_Linux_X86_ARM_v1.0.zip A sample file containing the audio of a telemetry file can be found here: https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetry-chessboard_packet.wav If URESAT-1 operates as intended, the project team plans to release a Linux program that will allow players to send their chess moves to the satellite, further enhancing the interactive experience.

Part of SpaceX's small satellite (smallsat) rideshare program, Transporter-8 carries dozens of small to pico-sized satellites and orbital test vehicles. This launch marks the 38th Falcon 9 rocket launch of 2023, showcasing the rocket's significance as the major workhorse in the space industry. As a rideshare launch, Transporter-8 doesn't have a primary mission but aims to lower costs for small spacecraft operators. The launch manifest for Transporter-8 includes an eclectic variety of missions. Among them is URESAT-1, a 1.5 P Pocketqube spacecraft from AMSAT-EA and the Spanish Amateur Radio Union (URE), equipped with an amateur radio payload that will attempt to play chess against opponents on Earth. Transporter-8's diverse manifest demonstrates the wide range of missions being pursued, from space manufacturing technology demonstration by Varda Space Industries to two cryptocurrency technology satellites (CRYPTO3 and MOXY-1) and a communications satellite for the Vatican (SpeiSat). This blend of missions highlights the growing importance and potential of small satellite deployments. With its rideshare model, SpaceX is enabling more affordable access to space for small spacecraft operators. By sharing the launch vehicle with multiple payloads, the costs are distributed among different customers, allowing them to realize their space ambitions at a fraction of the cost of a dedicated launch. The success of Transporter-8 adds to SpaceX's impressive track record, and if the company maintains its launch pace while incorporating successful Falcon Heavy rocket launches, it could be on track to achieve Elon Musk's ambitious target of 100 rocket launches by the end of 2023. SpaceX's dedication to advancing space exploration and commercial satellite deployments is evident in its consistent launch operations and commitment to driving innovation in the industry.

The challenge is to establish communication through the LEDSAT CubeSat digipeater, providing a chance to win a special prize: a QSL card issued by the ESA Education Office and the LEDSAT team. Running from June 26 to July 30, this challenge allows radio enthusiasts to engage with space technology and showcase their communication skills. LEDSAT, developed by students from Sapienza University in Rome's S5Lab research team with support from AMSAT Italia, is an educational 1U CubeSat that participated in the second edition of the Fly Your Satellite! program. Its primary objective is to demonstrate a LED-based payload for ground-based optical tracking. The successful launch of LEDSAT on Vega flight VV19 on August 17, 2021, marked a significant milestone for the project. To celebrate the launch, a competition was launched, encouraging participants from around the world to record the first signs of life from the spacecraft. To participate in the challenge, radio amateurs are invited to send a message to the ESA Education Office ESTEC Ground Station, with the callsign PI9ESA. The digipeater will be activated during specific time windows, with operators stationed at the ground station to receive incoming messages. Upon successful reception of a message, the sender's callsign and contact details will be documented on a personalized QSL card, acknowledging their accomplishment. The LEDSAT digipeater can store and retransmit digital messages sent to the satellite, acting as a transponder for long-distance communication. Messages can be retransmitted immediately or with an optional delay of up to two days. LEDSAT follows a Sun-Synchronous orbit, resulting in two communication windows each day ? around midday and midnight ? where contact can be established. Participants can predict passes precisely above the ESTEC ground station or their area of residence by using their favorite pass prediction software or obtaining the latest Two-Line Elements for LEDSAT from https://celestrak.org/NORAD/elements/gp.php?CATNR=49069. Due to LEDSAT's monitoring and housekeeping requirements and the potential high demand from operators, the digipeater activation time slots will follow a pattern of one day ON and one day OFF, with the switch-on/off always occurring at 00:00 UTC. This schedule will begin on Monday, June 26th at 00:00 UTC, and conclude on Sunday, July 30th at 24:00 UTC. While the challenge is supported by operators on a voluntary basis, efforts will be made to cover as many LEDSAT passes as possible, especially those occurring around local midday on weekdays. A detailed schedule of pass coverage will be published, so participants are advised to regularly check for updates. The LEDSAT digipeater uplink frequency is 435.310 MHz, the downlink frequency is 435.190 MHz, and the modulation type is GMSK using a CSP + Golay + ASM (AX100 Mode 5) protocol at 1200 baud. The LEDSAT team has prepared a software package and a user manual for connecting to the digipeater, available for download on the LEDSAT website at https://www.s5lab.space/index.php/ledsat-digipeater/. It is important to note that transmitting to the satellite is prohibited for those who are not licensed radio amateurs. However, non-licensed individuals can still participate in the challenge by listening to the messages transmitted by the ESTEC ground station. If they provide evidence of successful reception, including the date and time, they may also receive a customized QSL card. Participants are encouraged to mark their calendars, prepare their messages, and not miss the chance to connect and communicate with the LEDSAT spacecraft to receive their QSL card. Let's come together and make this event a memorable celebration of our shared passion for space exploration and amateur radio communication.

The rocket’s primary payload will be Astrobotic Technology’s Peregrine lunar lander, which will carry payloads for NASA and private companies under the space agency’s Commercial Lunar Payload Services program. Vulcan Centaur will also carry the KuiperSat-1 and KuiperSat-2 demonstration satellites for Amazon. The spacecraft will demonstrate technology for the company’s 3,236-satellite broadband constellation.

In his latest stunning footage, captured on June 9, Legault imaged the ISS whizzing past three sunspot groups. The entire solar transit lasted just 0.75 seconds. In addition, Legault captured these shots while two NASA astronauts, Stephen Bowen, KI5BKB, and Warren "Woody" Hoburg, KB3HTZ, were carrying out a spacewalk to install a new solar array outside the station.

Sunspots, X-class solar flares and CMEs (coronal mass ejections) are increasing in frequency and intensity on a daily basis. The peak of Solar Cycle 25 was not expected until late 2024 or early 2025 but it may be coming earlier and have a higher intensity than was predicted. One result of this increased activity is that the upper atmosphere and ionosphere of the earth becomes warmer and expands upwards. This means that spacecraft in low earth orbit experience more drag or resistance as a result of the increase in the number atoms they are having to displace as they travel around the globe. As a consequence, the spacecraft loose more kinetic energy and start to descend lower in orbital height, which, of course, makes the problem worse and a fiery end to the spacecraft is hastened. The actual effect is also dependant on the drag coefficient of the particular spacecraft…simply how much mass (the more the better) to how much surface area (the less the better). So in CubeSat terms, a 1U CubeSat, fairly full of stuff with a mass near the maximum of 1.3kg, will probably be better off than a half empty 3U CubeSat with deployable solar panels and other drag inducing protuberances. All TLEs (Two Line Elements) include a parameter called drag, it is usually a very small number preceeded by four or more zeros! Although this parameter is calculated by the system, it is not usually precise or even stable, so cannot be used to accurately predict deorbit dates when looking forward many weeks/months. It can give us a guide though! Alarm bells should ring when we only see two leading zeros. How does this effect our activities? Well for the FUNcube family, there are presently three active members! FUNcube-1, AO-73 was launched almost ten years ago in November 2013 into an elliptical polar orbit of approx 682×595 km. Presently those numbers are around 640×570 km so probably not too much to worry about. The drag number from the TLEs is, at the time of writing, 0.000074, a good number. The same applies to JY1SAT, JO-97. This was launched in December 2018 into a 573×590 km polar orbit. Presently those numbers are around 557×573 km and the current drag is listed as 0.000076. Unfortunately, however, the same cannot by said for Nayif-1, EO-88. This spacecraft was launched in February 2017 into a 496×507 km polar orbit. Currently the orbit parameters show a height of around 320 km with the drag at 0.00319. It is now well below the ISS and much lower than at launch. As mentioned, largely due to the random nature of the our star’s flux output on a day to day basis, it is not possible at this stage to accurately predict the likely deorbit date but it seems that it will certainly be before the end of this year. As the spacecraft continues to perform 100% nominally this is a great shame. Presently it is switching autonomously from high power telemetry when in daylight and with lower power telemetry and the transponder active when in darkness. The solar panels, battery and power system also continue to be reporting nominal numbers, essentially unchanged since the day of launch. It will therefore be a really sad moment when re-entry occurs but in the meantime everyone is encouraged to use the spacecraft whilst it remains available. To mark the event of EO-88/Nayif’s demise, AMSAT-UK is offering two awards. These will be individual framed certificates. Firstly, to the station who submits the last telemetry to the FUNcube Data Warehouse and also to who “guesses” or calculates the re-entry time and date most accurately. Submissions for this award must be made to EO88 ＠ amsat-uk.org before midnight (UTC) on July 4th 2023. So time is short to get your entries in. Good luck!

The satellite is a joint effort between AMSAT-EA, URE (the Spanish equivalent of ARRL), private companies, and universities. The URESAT-1 satellite, contained within the D-Orbit ION Orbital Transfer Vehicle (OTV), was not deployed directly from the Falcon-9 rocket. Instead, approximately one hour and twenty minutes after launch, the Falcon-9 released the OTV. URESAT-1 was deployed from the OTV at approximately 12:10 UTC on June 22, 2023. As of this writing, signals have not yet been received from the satellite. One of the primary objectives of URESAT-1 is to serve as an FM voice and FSK data repeater. Equipped with a Slow Scan Television (SSTV) camera, the satellite will transmit live images as well as stored images at regular intervals. It also features a chess game, enabling players on Earth to engage in a game against the satellite. Periodically, the satellite will transmit updates on the state of the game, including the chess board, the last movement made, and whether the next move belongs to the players or the satellite. The specified frequencies for communication with URESAT-1 are as follows: for uplink transmissions, 145.975 MHz or 145.925 MHz (auxiliary frequency) using FM voice without subtone, FSK 50 bps, AFSK, AX.25, APRS 1200/2400 bps. For downlink transmissions, the frequency is set at 436.888 MHz, and modes include FM voice, CW, FSK 50 bps telemetry, SSTV Robot 36, and a voice beacon with the callsign AO4URE. To provide further information regarding URESAT-1's transmissions, the AMSAT-EA organization has made available a comprehensive document that can be accessed at the following link: https://www.amsat-ea.org/app/download/13366685/AMSAT+EA+-+URESAT-1+Transmissions+description.pdf For those interested in decoding the telemetry, a Linux x86/ARM decoder is available for download at the following link: https://www.amsat-ea.org/app/download/13395017/URESAT-1_telemetry_decoder_Linux_X86_ARM_v1.0.zip A sample file containing the audio of a telemetry file can be found here: https://www.amsat-ea.org/app/download/13398144/URESAT-1_sample_FSK_telemetry-chessboard_packet.wav If URESAT-1 operates as intended, the project team plans to release a Linux program that will allow players to send their chess moves to the satellite, further enhancing the interactive experience.

Its baseline functions include telemetry, digital image downlink from an infrared camera, and digipeater with JT4G uplink/downlink. It will also provide chances for uploading and testing new waveforms and algorithms for radio communications and measurements in very long distance. Amateur radio orbit determination experiments, for example Very Long Baseline Interferometry (VLBI), are also possible with these links. Harbin Institute of Technology has previously successfully developed the first lunar amateur radio satellite, Longjiang-2 / DSLWP-B. (LO-94) As a subsequent mission, Lunar OSCAR II will continue offering various resources for communications relay and amateur radio research, and promoting the cooperation of amateur radio communities. The Lunar OSCAR II payload will be on board a lunar microsatellite with a volume of about 300x200x100 mm3 and a mass of about 14 kg and will utilize downlinks on UHF for telemetry and images using 250/500 baud GMSK with turbo codes and Digipeater using 4.375 baud $FSK with convolutional coding (JT4G). More information is available at https://by2hit.github.io/. The satellite is planned for a launch from Wenchang in 2024. A downlink on 437.750 MHz has been coordinated.

Just 10 years ago, a mere thousand or so operational satellites may have orbited our planet, but there will be tens or even hundreds of thousands a decade from now. Experts have been sounding alarm bells for years that Earth orbit is getting a bit too crowded. So how many satellites can we actually launch to space before it gets to be too much? Jonathan McDowell, an astrophysicist and astronomer at the Harvard-Smithsonian Center for Astrophysics warns the first signs that things are getting a little too tense are, in fact, already present. "It's going to be like an interstate highway, at rush hour in a snowstorm with everyone driving much too fast," he told Space.com when asked what the situation in orbit will be like if existing plans for satellite megaconstellations such as SpaceX's Starlink, OneWeb and Amazon Kuiper come to fruition. "Except that there are multiple interstate highways crossing each other with no stoplights." McDowell's British colleague Hugh Lewis is another frequently heard voice of caution. In a post published on Twitter on Jan. 13, Lewis stated that "the overall number of conjunctions predicted for 2022 was 134% higher than the number for 2020 and 58% higher than 2021, exceeding 4 million." That doesn't mean that on 4 million occasions objects in space came close to a collision ? just that managing traffic in space is getting much more complicated than it has ever been in the past. Take SpaceX's Starlink as an example. According to information submitted to the U.S. Federal Communications Commission (FCC) in December last year, SpaceX's autonomous collision-avoidance system performed 26,037 orbital avoidance maneuvers with its Starlink satellites in the two-year period between Dec. 1, 2020 and Nov. 30, 2022. That means each Starlink satellite of the nearly 4,000 that have been launched to date performed, on average, 12 avoidance maneuvers during that time. But the size of SpaceX's current constellation is less than 10% of what the company plans to deploy. Within the next 10 years, the number of Starlink satellites in orbit may rise to 42,000. Add to that the up to 4,000 satellites that OneWeb wants to launch, another 3,200 of Amazon's Kuiper craft and 13,000 satellites of China's envisioned Guowang system, and it becomes obvious that things are set to get much more heated. According to the FCC document, SpaceX claims that each of its satellites has a sufficient amount of fuel on board to perform 350 collision-avoidance maneuvers over its expected five-year lifetime. But that number could be reached remarkably soon, according to Lewis' calculations. In short, less than five years from now, Starlink satellites may be running out of fuel in a shorter period of time than their designed lifetime because of the sheer number of avoidance maneuvers they will have to perform.

The downlink frequency on which to listen is 145.800 MHz worldwide. Quick list of scheduled contacts and events: No contacts currently scheduled 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 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.

During its stay in orbit, Spei Satelles will transmit a radio signal that can be received by amateurs. The signal contains messages of hope from the magisterium of Pope Francis. Spei Satelles (the Latin words for Satellite of Hope) operates in a sun-synchronous low Earth orbit at about 525 km of altitude from the Earth's surface. At a frequency of 437.5MHz (Editor's note - this satellite is not coordinated by the IARU and AMSAT encourages radio amateurs to decline to offer telemetry collection or other technical support to groups that launch satellites that are not IARU coordinated and do not offer amateur communications opportunities) it transmits GMSK at 9600 bit/s AX.25. Spei Satelles also contains a nanobook, a 2x2x0.2 mm silicon slab on which the images, speeches, and readings by Pope Francis on March 27, 2020, in the midst of the pandemic, were imprinted by nanotechnologies. The satellite hitched a ride aboard Space X’s Falcon 9 rocket launching from the Vandenberg Space Force Base in California on June 10, after being blessed by Pope Francis on March 29 at his General Audience in St. Peter’s Square.
