In today's signal, we start with CSIRO publishes largest-ever map of cosmic magnetic fields using 4 million galaxies and also look at HETDEX releases 600 million spectra from the largest early-universe survey ever completed. Plus the latest in Missions & Launches, Business, Policy & Defense, and Global Roundup.

Australia's CSIRO has released SPICE_RACS, the largest map of cosmic magnetic fields ever produced, built by tracking how light from nearly four million galaxies twists as it crosses intergalactic space. The dataset is five times larger and more detailed than any previous effort, and for the first time covers the southern sky, a gap that had left researchers working from the same incomplete picture for two decades. The instrument behind it, the Australian Square Kilometre Array Pathfinder in Western Australia, can scan vast sky areas in a single pass. Scientists still lack a clear account of when and how magnetic fields first formed after the Big Bang, and the map has been released as an open dataset so researchers worldwide can probe specific galaxies, star-forming regions, and large-scale magnetic structure independently.

NASA has formally declared MAVEN lost, closing out a mission that ran more than a decade past its original one-year design life. The spacecraft's last signal reached Earth on December 6, 2025; when it reappeared from behind Mars, telemetry showed it had entered safe mode and was spinning uncontrollably, draining its solar-powered batteries. An anomaly review board concluded the probe likely lost power within hours and entered an unrecoverable state, though the root cause is still under investigation. MAVEN was the first Mars orbiter built specifically to study how the planet lost its atmosphere to the solar wind, and its archived dataset is expected to support research for years. NASA now has two active Mars orbiters, Odyssey and the Mars Reconnaissance Orbiter, both also operating well beyond their planned lifetimes.

The May 28 static-fire explosion at Blue Origin's Cape Canaveral pad has pushed AST SpaceMobile's direct-to-smartphone service target from late 2026 into the first half of 2027, a three-to-six month slip the company's chief strategy officer disclosed at a William Blair investor conference on June 2. AST had already absorbed the loss of a BlueBird satellite on a New Glenn launch in April without revising its schedule, but the pad damage proved harder to absorb. Blue Origin's CEO said June 1 that New Glenn could return to flight before year-end, though analysts consider a near-term return from that specific pad unlikely. AST says none of its next several missions were booked on New Glenn anyway, and it is actively spreading launches across SpaceX, ULA's Vulcan, and at least one undisclosed heavy-lift provider to maintain cadence toward its 45-satellite service threshold.

NASA engineers completed the last pre-shipment inspection of the Nancy Grace Roman Space Telescope's primary mirror on May 20, confirming the 2.4-meter optic survived shake testing without any misalignment or debris contamination. The team traced the full optical path from the mirror to Roman's Wide Field Instrument using a high-resolution zoom camera, verifying that precision tolerances remained intact. With the check complete, the telescope is being prepared for transport to Kennedy Space Center ahead of a launch window opening as early as August 30. Roman is NASA's next flagship observatory, designed to survey wide swaths of sky for dark energy signatures, exoplanets, and infrared transients.

Upcoming Launches

Muon Space unveiled Condor-Ultra, a satellite platform aimed at the orbital data center market, starting at 20 kilowatts of power and scalable to 100 kilowatts depending on mission requirements. At roughly 1,500 kilograms, it is three times heavier and five times more powerful than Muon's previous largest spacecraft, and is designed to stack inside SpaceX Starship for high-volume deployments. The platform supports NVIDIA's Space-1 AI inferencing module and will use Starlink laser links for inter-satellite data relay. A pathfinder launch is planned for 2028, with undisclosed customers already engaged. Muon is also opening a San Jose production facility this month capable of building up to 500 satellites per year.

Japanese electronics giant Murata Manufacturing has agreed to evaluate Xona Space Systems' Pulsar service as a timing source for data centers, financial networks, and 5G/6G infrastructure. Xona is building a 258-satellite low Earth orbit constellation designed to deliver stronger positioning and timing signals than GPS, which can be jammed, spoofed, or degraded in dense urban environments. Murata could embed Pulsar capabilities into communications modules and industrial electronics sold across multiple sectors. Murata's venture arm was an early Xona investor, and Xona says timing-dependent industries like banking and telecom could become customers before the full constellation is deployed.

The Hobby-Eberly Telescope Dark Energy Experiment has made its full dataset public after seven years of observations at McDonald Observatory. The release covers 600 million spectra from the Cosmic Noon period, roughly 10 to 12 billion years ago, when star formation was near its peak. The catalog includes over one million distant galaxies, 18,000 supermassive black holes, and 150,000 stars, compressed from half a petabyte of raw data down to 10 terabytes for practical use. Cloud-based supercomputing access through UT Austin's Texas Advanced Computing Center means researchers without large institutional resources can run analysis at scale, and the team built dedicated tools for AI-assisted exploration of the dataset.

European states are building new defense coalitions across land, air, and maritime domains, but military space operations remain fragmented and dependent on the United States. Programs like IRIS², ODIN's EYE, and ESA's European Resilience from Space initiative address infrastructure and dual-use services, but Europe still lacks the integrated command structures needed to conduct operations in a contested orbital environment. The UK, Germany, and France are each developing national counterspace capabilities without apparent joint planning, risking duplication. Meanwhile, Europe's most advanced orbital warfare work continues inside U.S.-led frameworks like Operation Olympic Defender and the Combined Space Operations initiative.

SMILE lifted off May 19 on a Vega C after a decade of joint development between ESA and the Chinese Academy of Sciences, but senior officials from both sides declined to commit to a successor mission. Budget constraints are the main obstacle: ESA science director Carole Mundell said both agencies want a new joint call for proposals but need funding secured first. Both programs have overlapping interests in habitability and exoplanets, with some informal coordination expected around China's Jupiter mission Tianwen-4 and a possible solar observatory.
