SpaceX Launches Transporter-17 Amid Concerns About the FutureSpaceX launched the latest in its Transporter series of rideshare missions July 7 as industry concerns increase about the program’s future.
A Falcon 9 lifted off from Vandenberg Space Force Base in California at 0712 UTC on the Transporter-17 mission to sun-synchronous orbit. The mission carried 81 payloads, according to SpaceX, including MarmotSat, a 3U CubeSat designed and built by students at the University of Victoria, Canada; MARINA, a cubesat built by Technical University of Košice, Slovakia; HADES-E2, a 1.5P PocketQube from AMSAT-EA; KOSTKA, a 1U Cubesat from Brno University of Technology, Czechia; and Maveric 3U CubeSat from the University of Southern California.

MarmotSat carries a VHF digipeater uplink and downlink on 145.875 MHz; a CW telemetry beacon on both 145.875 MHz and 29.410 MHz; and a DVB-S2 digital video beacon and a linear-frequency-modulation sounding downlink, both on 29.410 MHz in the 10-meter amateur satellite allocation. A separate telemetry, tracking and command subsystem operates on 436.125 MHz. (See AMSAT News Service bulletins ANS-186 from July 5 for details.)
MARINA serves as an experimental communication platform providing global HAM operators with an active digital transponder and Earth-imaging capabilities. The transponder supports GFSK AX.25 G3RUH 9600 Baud communication. It also transmits Earth observation images utilizing the robust SSDV (Slow Scan Digital Video) protocol. It has a VHF downlink at 145.925 MHz for digital transponder and telemetry, as well as a UHF downlink at 436.680 MHz for SSDV transmissions, CW beacon, and SatNOGS integration.
HADES-E2, also known as UNNE-1B, was built in cooperation with Universidad de Nebrija. It carries an SDR-based FM and FSK repeater. It also broadcasts a Codec2 digital voice message and includes an educational “guessing game” where clues are hidden weekly in its telemetry. Frequency coordination is in progress, but AMSAT-EA has proposed a 145.925 MHz uplink for modes: FM voice (no subtone) and FSK 200 bps, AFSK, AX.25, APRS 1200/2400 bps, and a 436.888 MHz downlink for modes: voice FM, CW, FSK 200bps-2400bps.
KOSTKA has a UHF downlink at 436.870 MHz for 9k6 AX.25 G3RUH GFSK telemetry, SSDV image transmission, a digipeater service, and a CW beacon.
Maveric carries spectral imaging experiments and has a 9k6 UHF downlink using Golay framing with GMSK at 437.575 MHz.
Like other Transporter missions, this launch carried a mix of new and returning customers, including those building out or refreshing constellations. Iceye had four radar-imaging satellites on the mission, while Spire had 10 of its Lemur satellites on the launch. Axelspace, a Japanese Earth observation company, flew seven of its GRUS-3 medium-resolution imaging spacecraft on the mission.
These and other companies have relied heavily on SpaceX rideshare missions for low-cost access to space on a regular schedule. However, there are growing concerns within the industry that SpaceX is winding down this program, at least using its workhorse Falcon 9 rocket.
In recent weeks, several partners and customers of those rideshare missions said SpaceX is not accepting Transporter reservations beyond late 2028 or early 2029. They added the missions on the manifest until then are nearly full. That has led companies like Exolaunch and SEOPS, which have arranged launches on Transporter missions, to buy their own Falcon 9 rideshare launches.
SpaceX has not commented on those claims, and its webcast for the Transporter-17 launch did not discuss any changes to the rideshare program.
However, anxiety extends to the availability of the Falcon 9 itself. SpaceX officials said last year they were near the peak of Falcon 9 launch activity and expected the number of launches to start to decline as the company ramps up Starship, its fully reusable heavy-lift vehicle.

14 Million Tracks and Counting: SatNOGS Hits Huge Milestone and Spots Spinning Satellite
Satellite Networked Open Ground Station (SatNOGS) is the biggest open network of satellite ground stations in the world. It is run by volunteers and managed by the Libre Space Foundation. Essentially, it gives anyone a web interface to remotely schedule and control ground stations across the globe.
One of the most significant aspects is that it relies entirely on regular people building their own setups at home. They use cheap, easy-to-find gear like a Raspberry Pi, a simple USB radio receiver, and basic antennas. Because the software handles all the tracking automatically using orbital data, the stations tune in and catch signals the exact moment a satellite flies overhead.
Big Milestones and Daily Tracking
On May 6, 2026, the network hit a massive milestone when it passed 14 million total observations. It was fitting for the amateur radio community that the record-breaking track happened to be LUSAT, which was Argentina’s very first mini-satellite. The network is incredibly busy right now, bringing in roughly 10,000 observations every single day.
Catching Anomalies in Real Time
SatNOGS does more than just routine tracking. It has turned out to be an amazing tool for spotting when things go wrong in space.
Back in May 2026, everyday users looking at SatNOGS signal charts noticed something weird with India’s Drishti satellite. By analyzing how the signal was fading in and out, independent trackers figured out that the spacecraft was actually tumbling in orbit at 3 degrees per second. This public data gave the world early proof that the satellite was in major trouble, months before official reports finally confirmed it was lost because of a solar storm.
Benefits to AMSAT Community
For AMSAT organizations, SatNOGS offers distinct advantages:
Global Backup: A dense, worldwide network ensures reliable backups if a local station misses a satellite pass.
LEOP Support: It helps teams identify and track new amateur spacecraft during the critical Launch and Early Orbit Phase (LEOP).
Asset Preservation: It ensures that historical assets like LUSAT continue to be actively monitored by enthusiasts worldwide.
Explore the DataThe community makes public observations, waterfall charts, and transmitter details completely open to the public. Real-time tracking data, along with guides on how to build a local ground station, can be found on the official website at https://satnogs.org/.

Securing the Future: Orbit Stabilization of Swift Observatory The Swift Rescue Mission (SRM), also referred to as the Swift Boost Mission, is a pioneering satellite-servicing project designed to recover and extend the life of NASA’s Neil Gehrels Swift Observatory. Developed by Katalyst Space Technologies, the mission utilizes a robotic servicing spacecraft named LINK to stabilize the observatory’s orbit and prevent its uncontrolled reentry into Earth’s atmosphere.

Changes to AMSAT TLE Distribution for July 10, 2026
Two Line Elements or TLEs, often referred to as Keplerian elements or keps in the amateur community, are the inputs to the SGP4 standard mathematical model of spacecraft orbits used by most amateur tracking programs. Weekly updates are completely adequate for most amateur satellites. TLE bulletin files are updated daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.
AMSAT is pleased to announce that modern forms of what are called General Perturbations data are being disseminated via modern formats including JSON, XML and KVN at https://newark192.amsat.org/gpdata/current/. The reason this change is being made is that we are running out of 5-digit catalog numbers and the TLE format is not viable for satellites launched after July of this year. See https://celestrak.org/NORAD/documentation/gp-data-formats.php for details.
These data are presently considered in beta test for the next two months while hosted on the test server newark192.amsat.org, and we are very open to community feedback at webmaster at amsat.org. Testers may experience outages and errors while we make improvements. We intend to put this into production on our main web server in July as we expect that satellites launched after this summer will require one of the new formats to accommodate longer object numbers. AMSAT will continue to publish TLE bulletins for satellites launched before July 2026 indefinitely.

+ AMSAT SA 2026 Space Symposium will be held Saturday, 1 August 2026. The event is conducted online from 10:00 – 14:00 SAST (08:00 – 12:00 UTC) to enable wide attendance without incurring large travel costs. The theme is “The new Amateur Radio World in Space,” exploring practical hands-on aspects of space activities and emerging technologies. Presentations will include outcomes of proposals for new geostationary amateur satellites, including innovative ground-based systems to link LEO and GEO satellite. Registration is free for members of IARU member societies, while non-members pay a small fee. Visit the AMSAT-SA website for registration details. (ANS thanks AMSAT-SA, for the above information.)
+ NASA’s Moon and Mars Exploration Analog (MMEA) continues to recruit research participants for its upcoming yearlong simulation season. Because the mission’s integrated habitats at the Johnson Space Center in Houston are designed to simulate deep space, participants will operate under the isolated conditions expected during crewed missions to the Moon or Mars. The current recruitment period is active for the year-long mission beginning no earlier than August 2027, during which continuous simulation operations in confined environments could be possible. The mission is HERA/CHAPEA only (HERA habitat spacecraft simulation, CHAPEA habitat base simulation). Volunteers are reminded to meet specific physical and educational requirements and to pass NASA’s physical and psychological assessments, so the mission results can be shared with the Human Research Program to help keep future astronauts safe and mission-ready. (ANS thanks NASA, the Human Research Program and the Artemis mission for the above information.)
+ NSF–DOE Vera C. Rubin Observatory (LSST) continues to reward the global scientific community as it begins its 10-year campaign to create the most comprehensive cinematic record of the Universe in history. Because the observatory’s 3200-megapixel camera—the largest digital camera ever built—has successfully completed system optimization, it is now capturing new, detailed images of the southern sky approximately every 40 seconds. The current Legacy Survey of Space and Time (LSST) runs through the next ten years, during which continuous filming of the dynamic Universe and the production of trillions of measurements should be possible. The survey is Wide-Field/Time-Lapse only (producing 10 terabytes of data and up to 7 million alerts of changes in the night sky every night). Researchers are reminded to utilize automated alert brokers to classify these changes and to ensure timely follow-up of fleeting cosmic events, so this unprecedented resource can be shared by as many scientists and members of the public as possible worldwide.
