<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">AMSAT Update Presented at 2026 CubeSat Developers Workshop Available Online<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">An update presented by AMSAT President Drew Glasbrenner, KO4MA, at the 2026 CubeSat Developers Workshop is now available for viewing on YouTube. The presentation provides an overview of AMSAT’s current
satellite development programs and future mission plans, along with its ongoing efforts to support amateur radio in space. The recorded session offers those unable to attend the workshop an opportunity to review AMSAT’s activities within the broader small
satellite community.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The CubeSat Developers Workshop, held April 14–16, 2026, at California Polytechnic State University in San Luis Obispo, California, is an annual three-day conference focused on small satellite development.
Now in its 23rd year, the workshop brings together participants from academia, industry, and government to share knowledge, research, and practical experience in CubeSat missions, with an emphasis on hands-on learning and collaboration.<o:p></o:p></span></p>

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">During his presentation, Glasbrenner provided an overview of AMSAT’s mission as a volunteer, educational organization dedicated to building and operating amateur radio satellites. He noted the organization’s
long history dating back to 1969 and highlighted the continued operation of early satellites such as AO-7, which remains functional more than five decades after launch when illuminated by the sun.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Glasbrenner then outlined AMSAT’s current satellite development efforts, focusing on the GOLF-TEE mission, a 3U CubeSat expected to be completed later this year or early next year. The satellite
is designed to carry a 30 kHz linear transponder for amateur communications, along with a 10 GHz high-speed experimental downlink and improved three-axis attitude control. He also described the follow-on Fox-Plus series of CubeSats, which incorporate a mix
of commercial hardware and AMSAT-developed radio payloads.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Additional work includes AMSAT’s development of linear transponder modules and other payloads designed for integration into university CubeSat missions. These systems allow partner institutions to
use the hardware for mission communications while also providing access to amateur radio operators when not in use. Glasbrenner also highlighted educational initiatives such as the CubeSat Simulator and youth outreach programs aimed at expanding student participation
in amateur satellite operations.<o:p></o:p></span></p>

<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">AMSAT-HB Announces Results of 2026 HB9RG Trophy Distance Competition<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">AMSAT-HB has released the results of the 2026 HB9RG Trophy Distance competition, held during the first two weeks of March to honor the legacy of Hans Rudolf Lauber, HB9RG, a pioneer in VHF and UHF
communications and early satellite experimentation. The event challenges operators to achieve the greatest possible distances using amateur satellites in Earth orbit. Unlike traditional contests, scoring is based on the sum of each participant’s ten longest
satellite QSOs rather than the total number of contacts. This format emphasizes technical skill, station optimization, and operating strategy. The results shown in the table reflect the combined distance of those ten longest contacts for each operator. The
2026 competition drew participants from multiple countries across three operating categories.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Category 1, designed for portable handheld stations using whip or telescopic antennas, had a single participant, DF2ET, who achieved a total distance of 8,920.65 kilometers (5,542.43 miles). The
operator recorded a maximum single contact of 1,843.41 kilometers (1,145.19 miles) between grid JO31 and KN56. In Category 2, which includes portable and more capable stations, KE9AJ placed first with a total distance of 71,581.90 kilometers (44,472.62 miles),
followed by VU3YFD and VA3VGR. The longest single contact in this category measured 7,480.98 kilometers (4,648.52 miles) between KE9AJ in EL99 and F4AZF in JN39 via AO-7. KE9AJ also recorded the highest average distance at 7,158 kilometers (4,447.30 miles).
Category 2 drew ten participants from seven countries.<o:p></o:p></span></p>

<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">Rocket Lab Launches Eight JAXA Satellites on Kakushin Rising Mission<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Rocket Lab successfully launched eight satellites for Japan late Wednesday night as part of its Kakushin Rising mission, supporting the Japan Aerospace Exploration Agency’s Innovative Satellite Technology
Demonstration Program. Liftoff occurred at 11:09 PM EDT Wednesday, April 22 (0309 UTC Thursday, April 23) from Rocket Lab’s Launch Complex 1 in New Zealand. The mission carried a diverse set of small satellites designed to test new technologies and expand
capabilities in low Earth orbit. The launch continues Rocket Lab’s steady cadence of dedicated smallsat missions.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The Electron rocket deployed all eight spacecraft into low Earth orbit at an altitude of approximately 336 miles (540 kilometers). Deployment occurred less than one hour after liftoff, in line with
mission expectations. Rocket Lab confirmed successful separation of all payloads shortly after the event. The mission marked the 79th launch of the Electron launch vehicle.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Kakushin Rising represents the second of two contracted launches for JAXA’s technology demonstration program. The first mission, RAISE and Shine, launched in December 2025 and carried the RAISE-4
satellite to orbit. Together, the missions highlight Japan’s continued investment in rapid, cost-effective access to space for experimental payloads. These efforts support the development of new satellite technologies and operational concepts.<o:p></o:p></span></p>

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The eight satellites on this mission include MAGNARO-II, KOSEN-2R, WASEDA-SAT-ZERO-II, FSI-SAT2, OrigamiSat-2, ARICA-2, Mono-Nikko, and PRELUDE. The payloads range from educational CubeSats to advanced
technology demonstrators, including systems for remote sensing, communications, and deployable structures. One satellite features an antenna that can expand to many times its stowed size using origami-inspired techniques. These missions provide valuable on-orbit
validation for emerging technologies.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Several of the satellites are IARU-coordinated, including MAGNARO-II, KOSEN-2R, WASEDA-SAT-ZERO-II, and ARICA-2, with amateur radio downlinks in the VHF and UHF bands. Early reports from the SatNOGS
network indicate that multiple satellites are already transmitting, with CW beacon signals received from MAGNARO-II, ARICA-2, WASEDA-SAT-ZERO-II, FSI-SAT2, and OrigamiSat-2 within hours of launch. These initial receptions confirm successful early operations
and provide immediate opportunities for amateur radio operators to monitor and decode signals.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Rocket Lab’s Electron rocket, a 59 foot tall (18 meters) launch vehicle, is designed to provide responsive and dedicated access to space for small payloads. The company continues to support commercial,
government, and research missions with frequent launches. Rocket Lab also operates a suborbital variant known as HASTE for hypersonic testing applications. The Kakushin Rising mission further demonstrates the growing role of small launch providers in enabling
international space missions.<o:p></o:p></span></p>

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ CelesTrak has reminded users that it transitioned to a nonprofit organization five years ago and moved its services to the
<a href="https://celestrak.org/">celestrak.org</a> domain at that time. While requests to the legacy .com domain have been redirected since then, the SSL certificate for the .com site expired on April 12, 2026. As a result, software or scripts still pointing
to the .com domain may now fail or produce security warnings. Users are advised to update their configurations to use the .org domain to ensure continued access to CelesTrak data services. CelesTrak remains focused on providing free orbital data and tools
to the space and satellite community. The organization also encourages users to support its mission through voluntary contributions. (ANS thanks
<a href="https://celestrak.org/">CelesTrak</a> for the above information)<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ The Federal Aviation Administration has grounded Blue Origin’s New Glenn following a launch incident on Sunday from Cape Canaveral. The rocket performed nominally during ascent but failed to place
its payload, AST SpaceMobile’s BlueBird 7 satellite, into the intended orbit. The spacecraft had been scheduled to deploy about 75 minutes after liftoff into a 286 miles (460 kilometers) circular orbit at a 49.4 degree inclination following a second upper
stage burn. The FAA classified the event as a “mishap” and has opened an investigation to determine the root cause and ensure public safety before allowing a return to flight. According to available telemetry, the payload reached only about a 95 miles (153
kilometers) orbit instead of the planned altitude, rendering it unsustainable. Despite the anomaly, Blue Origin successfully landed and recovered the booster for the first time, supporting future reusability and higher launch cadence. (ANS thanks
<a href="https://www.engadget.com/">Engadget.com</a> for the above information)<o:p></o:p></span></p>
<p class="gmail-isselectedend"><span style="font-size:13.5pt;font-family:"Georgia",serif">+ NASA engineers at Jet Propulsion Laboratory commanded Voyager 1 to shut down its Low-Energy Charged Particles experiment on April 17 in an effort to conserve dwindling
power and extend the spacecraft’s mission. The instrument had operated nearly continuously since launch in 1977, providing valuable measurements of ions, electrons, and cosmic rays in interstellar space beyond the heliosphere. Powered by a radioisotope thermoelectric
generator that loses about 4 watts per year, Voyager 1 now faces critically low power margins after nearly five decades in operation. A recent drop in power during a routine maneuver raised concern that the spacecraft’s fault protection system could automatically
shut down additional systems, prompting the team to act preemptively. Two science instruments remain active, continuing to return unique data from a region of space no other spacecraft has reached. Engineers expect the shutdown to provide about a year of additional
operation as they prepare further power-saving measures, including a planned system reconfiguration later this year. (ANS thanks
<a href="https://www.nasa.gov/">NASA</a> for the above information)<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ SpaceX has completed a full-duration static fire test of its next-generation Starship Version 3 upper stage ahead of the vehicle’s first flight. The test, conducted on April 14, involved firing
the engines while the rocket remained secured to the launch pad, demonstrating readiness for upcoming operations. Starship Flight 12, targeted for early to mid-May, will be the first launch of the larger and more powerful Version 3 configuration. When fully
stacked, the vehicle stands about 408 feet (124.4 meters) tall and features upgraded Raptor engines capable of delivering significantly greater performance. The new variant is designed to carry more than 100 tons to low Earth orbit, a substantial increase
over the approximately 35-ton capacity of the previous Version 2. NASA is now preparing for its Artemis 3 mission, which will test docking operations in Earth orbit between the Orion spacecraft and one or both contracted lunar landers, including Starship and
Blue Origin’s Blue Moon. (ANS thanks <a href="https://www.space.com/">Space.com</a> for the above information)<o:p></o:p></span></p>
