<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">AMSAT CubeSatSim Lite Available Again for Purchase Through AMSAT Store<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The AMSAT CubeSatSim Lite, a low-cost, fully assembled satellite simulator, is once again available for purchase through the
<a href="https://www.amsat.org/product/cubesatsim-lite-complete/">AMSAT Store</a>. The device is designed to help users learn about satellite communications by transmitting simulated telemetry signals that can be received with common amateur radio equipment.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Operating on the 70 cm amateur band at 434.900 MHz, the CubeSatSim Lite allows users to receive and decode signals using a wide range of radios and software-defined radio (SDR) setups. Digital telemetry
and images can be decoded using software such as FoxTelem, APRS decoders, or SSTV applications.<o:p></o:p></span></p>

<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">New “Ground Station” Software Streamlines Satellite Tracking and Decoding<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">A new open-source software project called “Ground Station” is gaining attention among amateur satellite operators as a unified platform for tracking, receiving, and decoding satellite signals. The
software combines multiple functions typically handled by separate tools into a single system, offering a more streamlined approach to satellite operations.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Tracking programs, SDR control software, recording tools, and decoding utilities are often used together, sometimes requiring manual setup for each pass. “Ground Station” aims to simplify this process
by automating the workflow from pass prediction through signal reception and decoding.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">At its core, the software provides real-time satellite tracking using orbital data, along with automatic updates of satellite elements. It supports a variety of software-defined radios, allowing
users to monitor and record signals from multiple satellites. The system also includes automated antenna rotator control and Doppler correction, helping keep signals centered during a pass.<o:p></o:p></span></p>
<p class="MsoNormal" align="center" style="text-align:center"><a href="https://www.amsat.org/wordpress/wp-content/uploads/2026/03/Ground_Station_Satellite_Tracking_View.jpg"><span style="font-size:13.5pt;font-family:"Georgia",serif;text-decoration:none"><img border="0" width="1024" height="677" style="width:10.6666in;height:7.052in" id="_x0000_i1050" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/03/Ground_Station_Satellite_Tracking_View-1024x677.jpg"></span></a><span style="font-size:13.5pt;font-family:"Georgia",serif"><o:p></o:p></span></p>

<a href="https://github.com/sgoudelis/ground-station">Ground Station GitHub</a>]<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The platform is capable of scheduling and executing satellite observations automatically, reducing the need for operator intervention. During a pass, it can record IQ or audio data and process common
digital modes, including telemetry formats used by many amateur satellites. This is useful for operators interested in telemetry collection, CubeSat monitoring, and general satellite experimentation.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">In addition to amateur radio satellites, the software integrates with tools such as SatDump to decode weather satellite transmissions, including NOAA APT and other imaging formats. This expands its
usefulness beyond traditional amateur satellites to include weather satellite reception and other downlink services commonly monitored by the amateur community.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">“Ground Station” is an early-stage, actively developed open-source project available on GitHub at
<a href="https://github.com/sgoudelis/ground-station">https://github.com/sgoudelis/ground-station</a>. Users can learn more about the software and access installation instructions there. As development continues, it offers a path toward more fully integrated
ground stations, lowering the barrier to entry for satellite reception while providing experienced operators with a flexible new tool to explore.<o:p></o:p></span></p>

<h2><span style="font-size:24.0pt;font-family:"Georgia",serif">Artemis II to Deploy International CubeSats into High Earth Orbit<o:p></o:p></span></h2>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">When Artemis II lifts off on NASA’s Space Launch System in early April, four international CubeSats will be carried into space inside the Orion stage adapter. The satellites will be deployed into
High Earth Orbit approximately five hours after launch, following separation from the upper stage and the Orion spacecraft.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">The CubeSats will ride within a ring-shaped adapter structure that connects NASA’s Orion spacecraft to the SLS interim cryogenic propulsion stage. After Orion separates and establishes a safe distance,
an onboard avionics unit inside the adapter will control deployment, releasing each CubeSat at one-minute intervals. This system ensures the satellites are deployed safely and without interference as the stage continues on its trajectory.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Although Artemis II’s primary objective is to send four astronauts on a crewed lunar flyby, the CubeSats will carry out independent scientific and technology demonstration missions. By flying as
secondary payloads, these satellites provide additional research opportunities without affecting the main objectives of the mission.<o:p></o:p></span></p>

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Participating space agencies include the German Aerospace Center, the Korea Aerospace Administration, the Saudi Space Agency, and Argentina’s National Commission on Space Activities. The four CubeSats
are named TACHELES from Germany, K-RadCube from South Korea, Space Weather CubeSat-1 from Saudi Arabia, and ATENEA from Argentina.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">Each satellite is designed to carry out a unique mission. Germany’s TACHELES will study the effects of the space environment on electrical components, helping inform future deep-space systems. Other
payloads will focus on radiation measurements, space weather monitoring, and validation of new technologies in a High Earth Orbit environment.<o:p></o:p></span></p>
<p><span style="font-size:13.5pt;font-family:"Georgia",serif">NASA officials note that CubeSats offer a relatively low-cost method for testing new technologies, though their small size presents challenges for long-duration missions. The Artemis II CubeSat program
highlights the growing role of international cooperation under the Artemis Accords, while expanding access to space and enabling new scientific investigations beyond Earth orbit.<o:p></o:p></span></p>

<p class="gmail-isselectedend"><span style="font-size:13.5pt;font-family:"Georgia",serif">+ Roscosmos launched Progress 94 cargo spacecraft at 11:59 UTC (7:59 a.m. EDT) on Sunday, March 22, aboard a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, carrying
approximately three tons of food, fuel, and supplies for the Expedition 74 crew aboard the International Space Station. The spacecraft was originally expected to dock autonomously at the space-facing port of the Poisk module on Tuesday, March 24, following
a two-day flight. Shortly after reaching orbit, one of its two KURS automated rendezvous antennas failed to deploy as planned, though all other systems continued to operate normally. As a result, cosmonaut Sergey Kud-Sverchkov manually piloted the spacecraft
during final approach using the TORU remote control system from inside the Zvezda Service Module. Progress 94 successfully docked at 13:40 UTC (9:40 a.m. EDT) on Tuesday, March 24, completing the resupply mission despite the earlier anomaly. The spacecraft
is expected to remain docked for about six months before departing the station for a planned destructive re-entry, disposing of trash loaded by the crew. (ANS thanks

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ About a month after an onboard anomaly caused a loss of contact with the Proba-3 Coronagraph spacecraft, mission controllers have successfully re-established communication. The Villafranca ground
station in Spain, operated by the European Space Agency (ESA), received telemetry from the spacecraft, confirming it is once again transmitting health and status data. The Coronagraph is currently in a stable safe mode while engineers conduct detailed system
checks to assess any potential damage. Its solar panel is properly oriented toward the Sun, allowing essential systems to remain powered and the battery to recharge. After weeks exposed to extreme cold, the spacecraft’s components will require time to warm
up before normal operations can resume. Mission officials say the recovery is an encouraging milestone, though careful analysis and gradual recovery steps will be required before the mission can fully return to nominal activities. (ANS thanks the

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ NASA’s Double Asteroid Redirection Test (DART) mission has demonstrated that a kinetic impact can alter the motion of an asteroid system, with new analysis confirming effects beyond the initial
impact. The 2022 impact into the small asteroid Dimorphos not only shortened its orbit around the larger asteroid Didymos, but also slightly changed the motion of the entire binary system around the Sun. Scientists measured a change in orbital speed of about
11.7 microns per second, a tiny shift that could have significant long-term implications for planetary defense. The impact generated a cloud of ejecta that enhanced the momentum transfer, effectively doubling the push delivered by the spacecraft. Observations
from both professional and amateur astronomers, including stellar occultation campaigns, were critical in confirming these results. Researchers note that even such small orbital changes, if applied early enough, could be sufficient to deflect a potentially
hazardous asteroid away from Earth. (ANS thanks <a href="https://www.space.com/">

<p><span style="font-size:13.5pt;font-family:"Georgia",serif">+ A unique NASA astronomy satellite may soon undergo an unprecedented rescue attempt as it faces an early end in orbit. The Neil Gehrels Swift Observatory, launched in 2004 to study gamma-ray bursts,
has been out of operation for more than a month and is gradually losing altitude due to atmospheric drag. NASA has awarded a $30 million contract to Katalyst Space Technologies to develop a robotic servicing spacecraft that will attempt to rendezvous with
Swift and raise its orbit, extending the mission’s life. The planned rescue mission, scheduled for launch as early as June, would mark one of the first commercial attempts to dock with and service a satellite not originally designed for in-orbit repair. Engineers
face significant challenges, including tight timelines, uncertain spacecraft conditions, and the risks associated with docking two large objects in low-Earth orbit. If successful, the mission could demonstrate a lower-cost approach to satellite servicing while
preserving a valuable scientific asset. (ANS thanks <a href="https://arstechnica.com/">
