Welcome back to Telemetry

A busy cycle in orbit and beyond. Let's get into it.

Using JWST's NIRSpec integral field unit, researchers have identified three separate accreting black holes inside a single galaxy observed when the universe was about 1.2 billion years old. Two sit just 190 parsecs apart near the galaxy's center and are expected to merge within roughly 700 million years; a third, more distant black hole appears to be slowly falling inward and would trigger a second merger. The black holes were detected through broad hydrogen-alpha emission at each location, a signature of gas swirling around an active black hole, with masses ranging from roughly 600,000 to 80 million times the Sun's mass. The finding adds to a growing body of JWST results suggesting that multi-black-hole systems were common in early galaxies, and the team modeled whether future mergers like these would be detectable by LISA, the planned space-based gravitational wave observatory.

China's new Long March 12B rocket made its first flight on June 1 with no advance airspace notices, a departure from standard practice that typically signals an upcoming Chinese launch. The rocket, built by state contractor CASC, lifted off from Jiuquan and delivered a batch of Qianfan broadband constellation satellites to orbit, potentially bringing that network to 180 satellites if the typical 18-satellite batch size was used. The vehicle is a two-stage kerosene-LOX rocket roughly 72 meters tall with a 20,000 kg LEO capacity, putting it in the same class as Falcon 9. Though designed for reuse, this flight did not attempt first-stage recovery; CASC says that test will come later, a meaningful caveat given that both of China's previous recovery attempts, on Long March 12A and Zhuque-3, failed on descent.

A May 28 static-fire test explosion at Cape Canaveral's Launch Complex 36 destroyed New Glenn's transporter-erector, collapsed a lightning tower, and damaged the main launch tower. Blue Origin has offered no rebuild timeline, but SpaceX's 2016 Falcon 9 pad explosion took 15 months to repair, and industry observers expect a similar or longer gap here. The timing hits hard: NASA had awarded Blue Origin two Blue Moon lunar lander contracts just two days before the explosion, Amazon is counting on New Glenn for more than a third of its 3,232-satellite Leo constellation, and AST SpaceMobile was relying on the rocket's high per-launch capacity to hit its year-end satellite targets. The accident lands in an already supply-constrained launch market where demand has outpaced available capacity for years, with few near-term alternatives for displaced customers.

A new agreement between the UK government and commercial station operator Vast would allow the UK Space Agency to secure sponsorships funding a spaceflight for John McFall, a Paralympian and NHS surgeon who lost his leg at 19. ESA selected McFall in 2022 for a study on physically disabled astronauts, and he was cleared medically fit for a long-duration ISS mission last year. If he flies, his research would cover how prosthetics behave in microgravity, musculoskeletal adaptation, and human movement in weightlessness. McFall says a flight is not guaranteed, and significant training remains before any mission assignment.

The Solar wind Magnetosphere Ionosphere Link Explorer, known as SMILE, lifted off from Europe's Spaceport in French Guiana on May 19. The joint ESA and Chinese Academy of Sciences mission is designed to observe how the solar wind interacts with Earth's magnetosphere in real time, giving scientists a continuous view of the processes that drive space weather. Ground-based and other space assets can detect space weather effects, but SMILE's dedicated vantage point is intended to reveal the full dynamic picture of how solar particles reshape Earth's magnetic environment. ESA released a timelapse of launch operations to mark the milestone.

PLD Space has revised its planned investment in a dedicated launch pad at the Guiana Space Centre to €35 million, up from €16 million estimated in late 2024 and an original €10 million figure from mid-2024. The company closed a €180 million Series C round in March 2026 and secured €30 million from the European Investment Bank in April, though it has not explained how much of the cost increase those funds enabled. Civil works at the site are expected to finish in summer 2026, with the facility targeting readiness for MIURA 5's inaugural flight before year-end.

A line in SpaceX's amended IPO filing disclosing that the company may issue significant equity for future transactions sent Tesla shares down 5%, with some institutional investors reading it as a potential precursor to a Tesla acquisition. Analyst Gary Black estimated a deal could dilute Tesla shareholders by 28%, given SpaceX's higher expected valuation multiple. Retail advocates pushed back, arguing a merger-of-equals exchange ratio would reprice Tesla upward toward deal value, potentially adding $450 billion to its market cap. SpaceX is expected to begin trading publicly within weeks.

Analyzing the full GWTC-4 gravitational wave catalog from LIGO-Virgo-KAGRA, researchers have identified three sub-populations of binary black hole mergers that each follow different merger rate patterns, ruling out a single universal rate across all detected pairs. The dividing line sits at 45 solar masses: black holes above that threshold show a delay-time distribution that differs sharply from lighter pairs and depends strongly on mass ratio and spin. Equal-mass systems near zero spin appear to merge later relative to their progenitor star formation than other configurations. Merger rates at redshift zero span roughly 0.6 to 12 mergers per cubic gigaparsec per year across the three groups, a spread that points to multiple distinct formation pathways operating in parallel.

JWST's NIRSpec instrument has identified carbon disulfide (CS₂) in the atmosphere of V1298 Tau e, a planet roughly 20 million years old with about 15 Earth masses but a Jupiter-sized radius. The detection clears an 8-sigma confidence threshold using spectral features between 4.3 and 4.7 micrometers, and photochemical models confirm the CS₂ abundance is consistent with a hydrogen-helium atmosphere under intense UV irradiation. The result is notable because V1298 Tau e's neighbor, planet b, shows sulfur dioxide instead, meaning two planets in the same young system are operating in chemically distinct atmospheric regimes. That divergence may point to different formation histories or evolutionary paths within a single planetary system.

A provision in the One Big Beautiful Bill Act now lets spaceports and adjacent space facilities tap the tax-exempt private activity bond market, the same low-cost, long-tenor financing that funds airports and seaports. Spaceports have historically relied on shorter-term, higher-cost capital despite being long-lived assets, producing chronic underinvestment. The new authority has no project size cap, allows 100% private use of bond-financed facilities, and extends to manufacturing and industrial operations with a nexus to a licensed launch or reentry site. That last point is significant: it creates a financing framework for the clustered industrial ecosystems that make mature transportation hubs viable.

ESA has selected Hibidis and SOVA-S as its next Scout-class Earth observation missions, following a 10-month competition. Hibidis will use hyperspectral imaging to assess forest biodiversity by capturing understory light from multiple angles, while SOVA-S will track atmospheric gravity waves with a shortwave infrared imager to improve weather modeling. Both missions must launch within three years of selection on a budget capped at 35 million euros each. The Scout program, designed for low-cost rapid development, now has four missions in the pipeline alongside the already-orbiting HydroGNSS.
