It runs entirely in a web browser on desktop and mobile devices, with no login, installation, or plug-ins required.<o:p></o:p> For amateurs who came to satellite operating after the era of paper tracking devices, the original OSCARLOCATOR was a circular, azimuthal-equidistant map of one hemisphere paired with a rotating clear overlay. By aligning the overlay to a satellite's equator crossing, an operator could determine where the spacecraft would appear in the sky and when it would be in range — all without a computer. N8HM's web version preserves that look and method while adding the convenience of live, on-demand computation.<o:p></o:p> <a href="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/OscarLocator_Web_Simulator_Main_Screen.jpg"><img border="0" width="650" height="650" style="width:6.7708in;height:6.7708in" id="_x0000_i1056" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/OscarLocator_Web_Simulator_Main_Screen-1024x1024.jpg"></a><o:p></o:p> <table class="MsoNormalTable" border="0" cellspacing="0" cellpadding="0" style="margin-left:166.1pt;border-collapse:collapse"> <tbody> <tr> <td width="654" valign="top" style="width:490.5pt;padding:0in 5.4pt 0in 5.4pt"> The OSCARLOCATOR Web Simulator, showing the polar azimuthal-equidistant map, ground track, range circle, footprint, and the station and sweep controls.<o:p></o:p> </td> </tr> </tbody> </table> The simulator renders the familiar polar azimuthal-equidistant map as well as a QTH-centered version, automatically choosing the North or South polar sheet for the operator's location. It draws the satellite's ground track with 10-minute time marks, plots a range circle over the operator's station, and shows the spacecraft's instantaneous footprint.

The mission will attempt to rendezvous with NASA's Swift Observatory and raise its orbit, potentially extending the life of the 22-year-old space telescope. The launch is expected to mark one of the first operational attempts to capture and service an unprepared satellite already in orbit.<o:p></o:p> Swift was launched in 2004 to study gamma-ray bursts, among the most energetic events in the universe. Although the observatory remains scientifically productive, it was built without propulsion capable of maintaining its orbit. Atmospheric drag has gradually reduced Swift's altitude over the past two decades, and increased solar activity accelerated that decay. NASA determined the spacecraft was at risk of descending too low for safe servicing operations later this year.<o:p></o:p> To preserve the observatory, NASA selected Katalyst Space Technologies in 2025 to develop a rapid-response rescue mission. The company designed and built the LINK servicing spacecraft in less than one year, an unusually short schedule for a mission of its complexity. LINK carries electric propulsion and a robotic capture system designed to attach itself to satellites that were never intended to be serviced in orbit.<o:p></o:p> <a href="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/LINK_Servicing_Spacecraft_And_Pegasus_XL-scaled.jpg"><img border="0" width="1024" height="593" style="width:10.6666in;height:6.177in" id="_x0000_i1052" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/LINK_Servicing_Spacecraft_And_Pegasus_XL-1024x593.jpg"></a><o:p></o:p> Katalyst Space's LINK servicing spacecraft is integrated with its Pegasus XL launch vehicle. [Credit: <a href="https://x.com/NASA">NASA</a>/Ron Beard]<o:p></o:p> Following launch, LINK will enter orbit and begin initial spacecraft checkout and commissioning activities. In the coming weeks, the spacecraft is expected to perform a series of orbital maneuvers to match Swift's orbit before attempting a close approach. Once in position, three robotic arms will be used to capture the observatory and establish a secure mechanical connection.<o:p></o:p> The mission is expected to mark the final flight of Northrop Grumman's Pegasus XL launch vehicle. First flown in 1990, Pegasus pioneered commercial air-launched access to space and completed dozens of missions during its 36-year career. The launch will utilize the last Pegasus XL rocket remaining in inventory and will be conducted from the L-1011 carrier aircraft Stargazer, believed to be the last operational Lockheed TriStar aircraft still flying.<o:p></o:p> If successful, the Swift rescue mission could establish a new model for extending the lives of aging spacecraft. Beyond preserving a valuable scientific observatory, the mission will demonstrate technologies that may one day allow commercial operators and government agencies to service satellites rather than replacing them. The mission is being closely watched as a potential milestone in the growing field of commercial on-orbit satellite servicing.<o:p></o:p> Read the full article at: <a href="https://arstechnica.com/space/2026/06/a-bold-satellite-rescue-mission-came-together-in-record-time-but-will-it-work/"> https://arstechnica.com/space/2026/06/a-bold-satellite-rescue-mission-came-together-in-record-time-but-will-it-work/</a><o:p></o:p> [ANS thanks <a href="https://x.com/StephenClark1"> Stephen Clark</a>, <a href="https://arstechnica.com/">Ars Technica</a>, for the above information]<o:p></o:p> <div class="MsoNormal" align="center" style="text-align:center"> <hr size="2" width="100%" align="center"> </div> <h3 align="center" style="text-align:center">Buying from DX Engineering?

The spacecraft, known as Victus Haze Puma, was placed into a sun-synchronous orbit and will participate in a military demonstration designed to test rapid response capabilities and on-orbit spacecraft operations.<o:p></o:p> Victus Haze is the fourth mission conducted under the Space Force's Tactically Responsive Space (TacRS) program. The initiative seeks to demonstrate how commercial launch providers and spacecraft manufacturers can rapidly deploy satellites when needed. Unlike earlier demonstrations that focused primarily on launch readiness, Victus Haze expands the concept by evaluating spacecraft operations after reaching orbit.<o:p></o:p> Following launch, the Puma spacecraft entered a commissioning phase before beginning rendezvous and proximity operations with another spacecraft already in orbit. The mission will pair Rocket Lab's vehicle with True Anomaly's Jackal-004 spacecraft, which launched in May aboard a SpaceX Falcon 9 rideshare mission. During the exercise, the spacecraft will perform a variety of maneuvers intended to demonstrate space domain awareness and the ability to characterize nearby objects in orbit.<o:p></o:p> <img border="0" width="1024" height="683" style="width:10.6666in;height:7.1145in" id="_x0000_i1050" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/Rocket_Lab_Victus_Haze_Launch-1024x683.jpg"><o:p></o:p> A Rocket Lab Electron rocket lifts off carrying the Victus Haze Puma spacecraft for the U.S. Space Force's Victus Haze orbital exercise. [Credit: <a href="https://rocketlabcorp.com/">Rocket Lab</a>]<o:p></o:p> The mission also showcased the responsiveness of Rocket Lab's launch system. After receiving a formal launch order from the Space Force, the company launched the Electron rocket within 16 hours and 42 minutes, surpassing the program's 24-hour launch requirement. Rocket Lab reported that mission planners calculated a final trajectory to a previously undisclosed orbit, updated flight software, and coordinated ground station support within only a few hours of receiving the order.<o:p></o:p> Victus Haze builds on lessons learned from the Victus Nox mission conducted in 2023. That earlier demonstration proved that commercial providers could rapidly launch a satellite following a short-notice tasking. Victus Haze extends the concept by demonstrating that responsive space operations can continue after launch, including the ability to maneuver spacecraft, inspect nearby objects, and gather information about activities occurring in orbit.<o:p></o:p> Space Force officials view these capabilities as increasingly important as Earth orbit becomes more crowded and strategically significant. Future military and civil missions may require the rapid deployment of spacecraft to replace damaged satellites, investigate unusual activity, or provide additional sensing capabilities. Through partnerships with commercial companies such as Rocket Lab and True Anomaly, the Victus Haze mission aims to demonstrate that these capabilities can be delivered on operational timelines measured in hours and days rather than months.<o:p></o:p> Read the full article at: <a href="https://spacenews.com/rocket-lab-launches-satellite-for-u-s-space-force-victus-haze-responsive-space-exercise/"> https://spacenews.com/rocket-lab-launches-satellite-for-u-s-space-force-victus-haze-responsive-space-exercise/</a><o:p></o:p> [ANS thanks <a href="https://x.com/Sandra_I_Erwin"> Sandra Erwin</a>, <a href="https://spacenews.com/">SpaceNews</a>, for the above information]<o:p></o:p> <div class="MsoNormal" align="center" style="text-align:center"> <hr size="2" width="100%" align="center"> </div> <h2>Researchers Propose StormWall System to Reduce Solar Storm Impacts<o:p></o:p></h2> Scientists have proposed a new concept called StormWall that could one day help protect satellites, communications systems, and power infrastructure from severe solar storms. The idea, described in a recent paper published in the journal Space Weather, would use a fleet of spacecraft to temporarily strengthen Earth's natural magnetic defenses when dangerous space weather is approaching.<o:p></o:p> Earth is normally protected by its magnetosphere, a magnetic field that deflects much of the charged particle radiation emitted by the Sun. During powerful solar eruptions, however, interactions between the solar wind and Earth's magnetic field can allow large amounts of energy to enter near-Earth space. These events can disrupt satellite operations, radio communications, navigation systems, and electric power grids.<o:p></o:p> The proposed StormWall system would deploy six spacecraft in geosynchronous orbit. Each spacecraft would carry stores of material such as barium, lithium, sodium, or calcium. When a major solar storm is detected, the spacecraft would release the material into space, where sunlight would ionize it and create an artificial cloud of plasma.<o:p></o:p> <img border="0" width="1024" height="804" style="width:10.6666in;height:8.375in" id="_x0000_i1049" src="https://www.amsat.org/wordpress/wp-content/uploads/2026/06/StormWall_Magnetosphere_Concept-1024x804.jpg"><o:p></o:p> An ESA illustration depicts the interaction between charged particles from the Sun and Earth's magnetosphere. [Credit: <a href="https://www.esa.int/">ESA</a>]<o:p></o:p> Researchers believe this plasma cloud could increase the mass density along the sunward boundary of the magnetosphere. Computer simulations suggest that the added material would reduce the efficiency of magnetic reconnection, the process that allows solar storm energy to penetrate Earth's magnetic shield. By slowing this process, StormWall could lessen the severity of geomagnetic storms reaching Earth.<o:p></o:p> To evaluate the concept, the research team simulated the effects of the May 2024 "Mother's Day" geomagnetic storm. Their results indicated that StormWall would not eliminate the storm entirely but could reduce key measures of storm intensity by more than 50 percent. The researchers also concluded that the amount of material required and the launch capabilities needed for the system are within the reach of current technology.<o:p></o:p> The concept remains a theoretical proposal and no StormWall mission has been approved or funded. Nevertheless, the study represents an unusual approach to space weather mitigation, shifting the focus from forecasting solar storms to actively reducing their impact. As satellite constellations and other orbital infrastructure continue to expand, researchers suggest that large-scale protective systems may become increasingly attractive in the future.<o:p></o:p> Read the full article at: <a href="https://www.space.com/astronomy/earth/scientists-propose-spraying-chemicals-into-earths-magnetic-field-to-protect-us-from-powerful-solar-storms"> https://www.space.com/astronomy/earth/scientists-propose-spraying-chemicals-into-earths-magnetic-field-to-protect-us-from-powerful-solar-storms</a><o:p></o:p> [ANS thanks <a href="https://x.com/skuthunur"> Sharmila Kuthunur</a>, <a href="https://www.space.com/">Space.com</a>, for the above information]<o:p></o:p> <div class="MsoNormal" align="center" style="text-align:center"> <hr size="2" width="100%" align="center"> </div> <h3 align="center" style="text-align:center">The 2026 Coins Are Here!

Event organizer Sean Borgerson, KK7OVF, noted that KO6MBI is relatively new to amateur radio satellites and encouraged operators to listen for him on the air. Bird Chaser Bingo is a summer-long activity that challenges operators to complete satellite-themed operating objectives involving contacts, grids, satellites, and special operating situations. Participants can earn recognition for completing traditional bingo patterns or attempt the more difficult Full Eclipse by finishing the entire card. The event runs through August 31, 2026, with completed cards due by September 15, 2026.

The spacecraft is designed to carry cargo and research payloads to low Earth orbit and safely return them to Earth for recovery. Starfall can accommodate up to 1,000 kilograms (2,200 pounds) of payload and is intended to support applications such as orbital manufacturing and scientific research. The capsule uses a carbon-fiber heat shield, nitrogen gas attitude-control system, and parachute-assisted splashdown recovery. During the June 23 flight demonstration, SpaceX targeted a recovery area in the Pacific Ocean approximately 1,300 kilometers (700 nautical miles) off the U.S. West Coast. The mission marked Starfall's first flight test, with at least one additional demonstration mission planned.

The QuadRF operates from 4.9 to 6.0 GHz in the C-band and provides four full-duplex transmit and receive channels with up to 1 watt of output power per antenna. The kit includes four dual-polarization antennas, an integrated Raspberry Pi 5, and open-source software for beamforming and phased-array experimentation. Scale RF says the design is intended as the building block for larger phased-array systems, including its planned MoonRF architecture for Earth-Moon-Earth communication and radio astronomy. The complete QuadRF kit is priced at $499 during the Crowd Supply campaign, with initial deliveries expected this fall. Additional information is available on the Crowd Supply campaign page at <a href="https://www.crowdsupply.com/scale-rf/quadrf">https://www.crowdsupply.com/scale-rf/quadrf#</a>.

The system generates electricity by combining hydrogen and oxygen into water, then recharges by splitting the water back into its original gases for repeated use. The technology could provide a lighter alternative to batteries while storing enough energy to power habitats, rovers, and other lunar systems through the Moon's two-week-long nights. Engineers recently began testing the complete integrated system, including storage of the hydrogen and oxygen produced during recharge. Data gathered during the test campaign will help prepare the technology for future environmental testing under simulated lunar conditions. If successful, regenerative fuel cells could become an important part of the infrastructure needed to support sustained human exploration of the Moon.
