A Long March 7A rocket exploded about 85 seconds after lifting off from Wenchang on Hainan island Aug. 10, apparently destroying its payload, according to amateur footage. China Aerospace Science and Technology Corporation (CASC) had not confirmed the failure by the time of reporting. State broadcaster China National Radio had named the payload as Zhongxing-4B, a communications satellite bound for geosynchronous transfer orbit and thought to serve military users.

The failure came during the core stage's initial burn, before the roughly three-minute first-stage separation. It was China's 56th orbital attempt of 2026 and its fourth failure. The 60-meter 7A, which lofts up to 7 tons to GTO, failed on its 2020 debut before a run of successes, most recently launching Tianlian-3 in late July. Because the 7A shares YF-100 engines with the Long March 5, upcoming missions including the Aug. 24 Chang'e-7 lunar lander could face review.

Astronomers have released the largest-ever two-dimensional map of the universe, cataloguing nearly 4 billion celestial objects across roughly three-quarters of the sky, NSF NOIRLab said. The DESI Legacy Imaging Surveys map contains 5.6 trillion pixels built from 263,407 exposures gathered over 13 years across three ground-based surveys using telescopes at Kitt Peak in Arizona and Cerro Tololo in Chile, spanning visible and near-infrared light. Originally made to guide the Dark Energy Spectroscopic Instrument in building its 3D map, it records where stars, galaxies, supernovae, black holes and gravitational lenses appear.

Prior versions underpin more than 1,800 papers. The release aids searches for rare objects, galaxy-evolution studies and AI training for next-generation observatories like the Vera C. Rubin Observatory and Nancy Grace Roman Space Telescope. DESI, which finished its five-year survey early in April 2026, has found hints that dark energy may be weakening over time.

A radiation-shielding vest tested during NASA's uncrewed Artemis I mission in 2022 could significantly cut astronauts' exposure to solar storms, a study published in Science Advances found. The AstroRad vest, developed by Israeli startup StemRad with the Israel Space Agency and Lockheed Martin, uses hydrogen-rich plastic rather than lead, which can worsen radiation by triggering secondary X-ray or neutron showers. The 26-kilogram garment shields radiation-sensitive organs unevenly, yielding about 30% better protection than uniform shielding. Two tissue-mimicking female torsos, Zohar and Helga, flew in Orion, one vested, one not, fitted with over 5,600 sensors.

Orion met no solar storm, but modeling past events showed the vest would have cut the dose from a 1972 solar particle event by nearly 60%, sparing up to 193 days' equivalent exposure. Designed as an emergency countermeasure for solar particle events, it lets astronauts keep working outside a storm shelter. Researchers also demonstrated that AstroRad components can be 3D‑printed from recycled polyethylene aboard the International Space Station.

Bulgaria has begun building what it calls Europe's largest space and defense development center, on the site of the abandoned Dobroslavtsi military airfield near Sofia, led by satellite maker EnduroSat. The government approved a draft memorandum of understanding with the company to establish the hub, advancing national plans to build a centralized center for satellite assembly, testing and qualification.

EnduroSat in turn is financing the hub through a $49 million round involving Peter Thiel and $104 million from corporate investors including Google Ventures. First facilities include a Space Technology Development Centre, an educational campus, and a National Centre for Space Data Observation, Coordination and Management. The runway will be restored for continued state aviation use. Phase one runs three years.

EnduroSat already operates a 17,500‑square‑meter facility in Sofia capable of producing up to two ESPA‑class (Evolved Expendable Launch Vehicle Secondary Payload Adapter) satellites per day. The planned Dobroslavtsi site, however, is intended to support significantly larger platforms. EnduroSat’s next generation of spacecraft , marking a major scale‑up in the company’s manufacturing capacity. EnduroSat, expected to become Bulgaria's fourth unicorn, will assemble and test next-generation satellites that will fall in the one‑to‑three‑ton class and feature solar array spans comparable to the wings of a Boeing 737, aiming to cut space-data costs from $3,000–5,000 per gigabyte toward $1.

Bulgaria, which lacks a national space agency, is positioning itself as a European hub separate from ESA. Earth‑observation firm Sfera Technologies is developing an integrated data‑delivery system and sees the Dobroslavtsi project as a means to unify the country’s fragmented ecosystem. CEO Zdravko Dimitrov cited Bulgaria’s near‑full technology stack, including ground‑segment services across LEO, MEO and GEO, satellite manufacturing capabilities and strong academic talent. Sfera plans to support about a dozen satellites by 2026 and expand its ground‑station network in 2027, targeting demand in Europe, the United States and Southeast Asia.

NASA formally invited India to join its south‑polar Moon Base program during the ninth India–U.S. Civil Space Joint Working Group (CSJWG) meeting held Aug. 5–6 at ISRO headquarters in Bengaluru. The CSJWG, established in 2005 as the two countries' standing mechanism for bilateral space cooperation, was co-chaired by ISRO's M. Sankaran and, on the US side, the State Department's Wesley Brooks and NASA's Kathleen Karika; ISRO chairman V. Narayanan and US Ambassador Sergio Gor addressed the opening. The talks proceeded under the US-India TRUST (Transforming the Relationship Utilizing Strategic Technology) initiative, drawn from the February 2025 Modi-Trump joint statement.

The invitation builds on the Artemis Accords, which India signed in 2023 as the 27th of now 70 signatories, and on last year's joint NASA-ISRO NISAR synthetic-aperture-radar mission. The two sides agreed to advance open scientific-data-sharing cooperation under the Accords, discussed future science and human-spaceflight collaborations, and reaffirmed support for UN Committee on the Peaceful Uses of Outer Space (COPUOS) guidelines on the long-term sustainability of outer space activities. NASA plans a south-pole base over three phases through the 2030s (including hilltop habitats, nuclear power systems, and a scouting via hopping robots mission starting 2028, initial operating capability across 2029–2032, and a semi-permanent crew presence from 2032), a surface focus that followed its pause of the Gateway station. India separately targets its own lunar base, lunar-orbit station and crewed moon missions in the 2040s.

It is to be noted that the Accords, however, are not a multilateral treaty: each state signs a largely identical bilateral text with the United States rather than a jointly negotiated instrument, and critics contend the framework sets lunar-governance norms outside the consensus-based COPUOS process, i.e., the same body whose sustainability guidelines the meeting reaffirmed, in effect advancing rules the UN committee has not collectively adopted.

SpaceX has become a central supplier of the satellite networks underpinning the Pentagon's next-generation missile defense, not just its dominant launch provider, as the Space & Missile Defense Symposium opens against an exhibition floor still dominated by traditional missile and radar contractors. Recent Space Force awards totaling roughly $8.1 billion place the company at the center of the Golden Dome architecture: a $2.29 billion May contract for the Space Data Network communications backbone, targeted for an operational prototype by end-2027; a $4.16 billion award for the initial space-based Airborne Moving Target Indicator (AMTI) constellation; and a $1.6 billion order in late July for 18 Falcon 9 launches, completed in roughly two months, an unusually compressed timeline for its size. SpaceX cited more than $6 billion in Starshield military awards in its first public earnings report.

Because it builds satellites, communications hardware and launches in-house, SpaceX offers integration rivals cannot. The awards also show Space Force priorities favoring mature technology, lower nonrecurring engineering costs and delivery in months rather than years, which are terms that advantage an incumbent with existing hardware and leave little room for developmental risk against the 2027 deadline. The service nevertheless stresses competition, awarding $615 million to Rocket Lab, Systems & Technology Research and an undisclosed firm for alternative AMTI approaches.

Gen. Michael Guetlein flagged Golden Dome's 2027 reconciliation-funded gap while launching an industry portal; Northrop, Lockheed, Teledyne, L3Harris, Parsons and Voyager report flowing contracts across missile-warning, interceptors, directed energy and sensor work.

11 August, 2026

Gen. Michael Guetlein, who oversees Golden Dome, warned Aug. 11 that the missile-defense initiative faces a fiscal 2027 funding gap unless Congress finds a new financing route, telling the Space & Missile Defense Symposium that "if they don't figure out a result, there is no funding." The Pentagon seeks about $17.5 billion for 2027, but only $400 million sits in the base defense budget; the rest depends on a separate $350 billion reconciliation request facing resistance on Capitol Hill. Guetlein later softened that, saying he worries about timing, not whether money ultimately arrives, and defended the administration's roughly $185 billion cost estimate against higher outside figures, arguing critics extrapolate existing systems across US geography rather than pricing the architecture his office is building.

Golden Dome has moved quickly on funds already provided: $22.5 billion, 95% committed, has put radars, launchers, space-based interceptors and the Space Data Network under contract, atop roughly $24 billion supplied by a 2025 reconciliation law. The program has a first operational site, construction underway elsewhere and expected nearly complete by end-2027, and has run two classified tests ahead of a 2028 operational demonstration. Guetlein's office directly runs only command and control; other capabilities flow through the services and agencies, which is why spending surfaces within Space Force, Missile Defense Agency and Army programs. A recent presidential directive broadened the program's data access from agencies including the FAA, NASA and DHS, and a fall interagency exercise will probe legal and operational authorities that could complicate homeland defense, such as counter-drone operations, where responsibility shifts among military, federal and local hands depending on where a threat flies, being one example.

Meanwhile, contractors report money moving: Northrop's Kathy Warden said reconciliation funds went onto contract in the second quarter; the company builds on existing missile-warning, infrared-tracking and hypersonic-interceptor work and is teamed with Apex on a space-based interceptor concept. Teledyne's Robert Mehrabian called his firm "the primary supplier to just about everybody" through its mercury-cadmium-telluride infrared detectors. Lockheed's Jim Taiclet said a directed-energy system completed Golden Dome's first milestone test, tied to a planned 500-kilowatt laser for cruise-missile and drone defense. Parsons booked a $514 million MDA engineering option; L3Harris's Chris Kubasik cited a roughly $9 billion pipeline; and Voyager supplies subsystems under Lockheed's Next Generation Interceptor and Anduril's interceptor team.

Meanwhile, KBR, the defense and space intelligence provider is positioning without a material award yet. That positioning runs into Golden Dome's classification, where most architecture and technical detail is withheld to deny adversaries insight, even as the Pentagon asks industry to commit resources (engagement happens largely at the top-secret/Sensitive Compartmented Information level), KBR's Daniel Dant said, making unclassified discussion difficult and putting a premium on cleared relationships.

Separately, at the symposium, the Pentagon launched the Golden Dome for America Ecosystem Hub, an unclassified digital portal intended to give defense contractors, commercial technology firms, startups, investors and universities direct path to submit concepts and see the missile-defense program's technology needs before formal solicitations. Program lead Gen. Michael Guetlein said the hub is central to a broader effort to accelerate development of Golden Dome’s layered architecture of sensors, command‑and‑control systems and interceptors by reducing administrative barriers, expanding industry participation and strengthening supply‑chain resilience. He said that the site addresses a persistent barrier where most technical discussions occur at classification levels that shut out newer entrants, and he has already met individually with more than 500 companies.

The hub enables rapid concept submissions, real‑time visibility into capability gaps and access to capital tools. Submissions are vetted by a screening team, and a separate security group helps firms protect intellectual property and networks. The program also opened a shared data environment, with analytics and AI sandboxes, exposing its data to cleared industry, academia and agencies to build tools against a common architecture, since integrating military, commercial and government sensor data is a central challenge. Guetlein framed the effort around holding to the $185 billion cost estimate via commercial-off-the-shelf technology and competition, citing 12 teams building space-based-interceptor prototypes and two firms running supply-chain risk analysis.

The Pentagon is pressing defense contractors to expand missile-interceptor production after heavy use in Ukraine and the Middle East left US inventories at what CSIS analyst Tom Karako called "dire" levels. Recent multibillion-dollar agreements task Lockheed Martin and Northrop Grumman with raising output of PAC-3 MSE (Patriot Advanced Capability-3 Missile Segment Enhancement) and THAAD (Terminal High Altitude Area Defense) interceptors, following a $1 billion investment in L3Harris for solid-rocket-motor capacity. A roughly $2 billion Northrop framework adds it as a qualified second PAC-3 MSE motor source, creating program-level competition with L3Harris; a separate $1 billion deal has Northrop quadruple THAAD structural components for Lockheed, part of raising THAAD capacity from 96 to 400 interceptors a year (an increase requiring propulsion, seeker and structural suppliers to scale simultaneously).

U.S. Army Lt. Gen. John Rafferty said future missile defense needs a mix of high-end and cheaper interceptors, guns, electronic warfare and eventual directed-energy weapons, not just quantity. Solid rocket motors remain a chokepoint, and definitive awards await fiscal 2027 appropriations, which Karako expects little progress on before the midterm U.S. elections, constraining the ramp's schedule. Startups such as Machina, applying AI-driven robotic manufacturing, are also entering the field.

Impulse Space won $28 million more for two Mira spacecraft under the Victus Salo responsive-space series, while Amazon, Lockheed, Northrop, Rocket Lab and York each took $12 million to interface commercial satellites with SpaceX's Space Data Network.

12 August , 2026

The U.S. Space Force added $28 million to its existing Impulse Space contract, funding two additional Mira spacecraft for the Victus Salo tactically responsive space series. The modification brings the award total to $62.8 million and expands Impulse’s role in Tactically Responsive Space or TacRS, which is shifting from rapid‑launch demonstrations to testing maneuverable spacecraft that can reposition quickly in orbit.

Victus Salo 1 is slated to launch in 2027 carrying a Lincoln Laboratory payload, while Victus Surgo will use Impulse’s Helios kick stage to send a Mira toward geosynchronous transfer orbit for independent maneuvering. Mira, a high‑thrust chemical‑propulsion vehicle capable of hosting 300‑kilogram payloads, has flown three missions. Impulse, founded in 2021, is expanding deeper into national‑security space and was recently added to the National Security Space Launch Phase 3 Lane 1 provider pool.

The Space Force awarded $60 million to Amazon LEO for Government (a dedicated division of Amazon's low Earth orbit (LEO) satellite broadband network), Lockheed Martin, Northrop Grumman, Rocket Lab and York Space Systems to prototype how commercial satellites can interface with the Space Data Network, a low Earth orbit mesh architecture whose backbone is being built under SpaceX’s $2.29 billion SDN‑B contract. Each company received $12 million to demonstrate standardized, multi‑vendor connections for ground‑to‑space and space‑to‑space data transport over nine months, plus six‑month OTA agreements supporting the Space Force’s planned “space exchange point” orbital‑router concept.

The awards were made through the Space Data Network consortium, created to address integration and architectural challenges and reduce reliance on a single supplier. Col. Ryan Frazier said the work will validate methods for linking diverse commercial systems to the SDN core and establish interfaces enabling broader competition as the network expands.

Astrolight and ATMOS Space Cargo, the space return logistics developer, have signed a memorandum of understanding to demonstrate what they call the first in-flight optical communications link between a reentry vehicle and an orbiting satellite, planned for 2027. Lithuanian space and defense tech company, Astrolight will fly its ATLAS-X laser terminals aboard both ATMOS's PHOENIX reentry spacecraft and the test satellite, enabling real-time transfer of system and mission data at up to 2.5 gigabits per second during in-orbit operations and reentry, which is a capability so far tested only in ground labs.

Laser links carry data up to 100 times faster than radio frequency and resist jamming, interception and detection, useful as radio telemetry degrades during reentry. The companies frame the work as supporting Europe's push for independent cargo-return capability, including through ESA's LEO Cargo Return Services Initiative, which aims to reduce reliance on international partners.

Rocket Lab's GHOST packages Electron and HASTE rockets, launch infrastructure, ground support and range control into shipping containers; Neutron's medium-lift debut risks slipping to 2027; and Kepler booked Neutron for optical relay satellites, joining Rocket Lab's growing pre-flight backlog.

10 August, 2026

Rocket Lab unveiled a containerized, globally deployable launch system designed to enable suborbital and orbital missions from virtually any location.

The Global Hypersonic & Orbital Spaceport Technology or GHOST system packages the Rocket Lab Electron and HASTE rockets, ground support and range control into standard shipping containers to enable orbital and suborbital launches from anywhere and to support responsive launch campaigns and national security missions, the company announced Aug. 10 on its second-quarter earnings call. The company says that it will enable operations from additional locations beyond Rocket Lab’s fixed launch sites and provide military customers with greater flexibility for orbital and hypersonic test missions.

The first deployment, Launch Complex 4 at Kodiak, Alaska's Pacific Spaceport Complex, will add two pads for high-frequency campaigns, bringing Rocket Lab’s footprint to six pads across two hemispheres, alongside its New Zealand and Virginia (U.S.) sites; operational debut is a suborbital Alaska launch in 2027. Because Electron and HASTE share ground infrastructure, GHOST offers dual-launch capability aimed at missile-defense testing and sovereign launch demand. CEO Peter Beck said the system grew from a HASTE customer's request for greater mobility. Separately, Beck said Neutron, Rocket Lab's partially reusable rocket delayed from 2024, has completed significant testing and is on track to reach its Wallops pad in the fourth quarter.

At the same earning’s call, Rocket Lab said the window to launch its Neutron rocket for the first time this year is "narrowing," raising the prospect of another slip for the originally delayed from 2024, medium-lift partially reusable vehicle. Beck said flight hardware is moving into final checkout and assembly, on track for delivery to the pad in the fourth quarter (2026-Q4), though pad delivery precedes integrated stage testing and a first-stage static fire, the riskiest milestone before launch. Beck framed the pacing as risk-trading, prioritizing a production-ready system over an early flight. Neutron, unveiled in 2021 and which lofts up to 13,000 kilograms to low Earth orbit reusably, suffered a tank rupture in January, is maintaining its planned “one, three, five” annual cadence for initial years of service, with future increases tied to reusability.

Meanwhile, Canadian satellite and space telecom company, Kepler Communications has booked its first dedicated launch, placing next-generation optical relay satellites on Rocket Lab's Neutron rocket in one of several missions the Canadian operator plans for 2028.

Earlier Kepler satellites flew as rideshares, including on SpaceX's Falcon 9. The Tranche 2 satellites will support data rates up to 100 gigabits per second, against 2.5 Gbps for the current service, and include 10 built for the first element of ESA's HydRON program, which aims to demonstrate a multi-orbit, terabit-per-second transport system for extending the reach of terrestrial fiber networks. Kepler deployed 10 roughly 300-kilogram Tranche 1 satellites this year, part of a pivot from small IoT spacecraft to a relay network it credits with tenfold year-over-year revenue growth, which also underpins a hosted payload business. Disclosed hosted-payload partners include German wildfire-detection firm OroraTech, which has four thermal-imaging payloads aboard Tranche 1 satellites and also uses Kepler's orbital compute and data-relay capabilities.

The deal comes in the wake of a confidential customer booking five Neutron and three Electron launches in May (then Rocket Lab's largest launch contract), and in July the company won a $266 million U.S. Space Force award for up to 18 suborbital missions, its largest to date. Rocket Lab has drawn that demand despite Neutron having yet to fly.

BlackSky won an international imagery deal as sovereign demand climbs; Intuitive Machines booked a $600 million geostationary satellite order; and NOAA awarded Spire Global and PlanetiQ for radio-occultation weather and space-weather data.

11 August, 2026

BlackSky, real-time, space-based intelligence and imaging company, has secured a seven‑figure, multiyear international contract to supply an unnamed international customer with persistent satellite monitoring and on-demand tasking.

The contract is for combined Assured and On‑Demand monitoring services following a successful pilot. The customer will receive low-latency imagery from BlackSky's Gen-2 and Gen-3 constellations paired with AI analytics, viewed through its Spectra tasking platform, combining an on-demand global subscription with an assured subscription giving priority access over a regional area of operations. Gen-2, launched in 2021, provides dawn-to-dusk monitoring; Gen-3, launching since 2025 at 35-centimeter resolution, enables automated classification of vehicles, aircraft and vessels of military interest.

The award follows BlackSky’s second‑quarter report, where international subscription contracts accounted for more than 80% of funded backlog and overseas revenue rose 200% year over year. The company plans eight Gen‑3 satellites in orbit by year‑end and 12 to 15 for hourly revisits, with additional spacecraft built for Mission Solutions to support sovereign ISR demand and accelerate future deliveries.

13 August, 2026

Intuitive Machines disclosed a $600 million contract for three geostationary communications satellites from an undisclosed customer, signed in June and disclosed Aug. 13 in its second-quarter results. CEO Steve Altemus said the satellites, built on its IM 1300 bus acquired with Lanteris Space Systems (formerly Maxar), would be delivered over 30 months, but declined to say whether the order ties to the FCC's July decision clearing 160 megahertz of upper C-band for terrestrial use, which pays Eutelsat, SES and Telesat over $6 billion to vacate, obliging those operators to procure new satellites to move affected services. The company, which now has more than 80 spacecraft under contract, also holds over 70 orders for its smaller IM 300 satellites, including 18 for the Space Development Agency’s Accelerated Missile Defense Tranche 3 program.

Intuitive Machines said it is expanding production capacity in Houston and California and provided updates on its five‑satellite lunar communications constellation. Altus‑1 will launch in early 2027 on the IM‑3 lander mission, while the remaining four remaining lunar-communications satellites will shift to a dedicated 2028 launch to accelerate deployment and support Artemis missions.

U.S. National Oceanic and Atmospheric Administration (NOAA) awarded $3.7 million to Spire Global and $2.7 million to PlanetiQ for radio occultation data to support terrestrial and space‑weather forecasting from Sept. 18 to Dec. 1, 2026. Spire will provide 4,600 daily GNSS profiles and 1,200 temporal‑resolution enhancements which capture atmospheric changes through the day. PlanetiQ will deliver 4,200 profiles and 500 total electron‑content tracks, which feed space-weather forecasts.

The awards come as NOAA prepares a 10‑year, $2.35 billion IDIQ (an indefinite-delivery contract vehicle) contract to expand commercial environmental data use across weather and space‑weather models. PlanetiQ separately completed testing of its next‑generation GNOMES satellites ahead of launch later this year. NOAA shares commercial data with NASA, the Air Force, the Navy and international agencies for weather-prediction models. Spire said the award reflects confidence built through years of operational GNSS‑RO delivery.

CesiumAstro is acquiring Jariet Technologies, a fabless semiconductor firm, to bring radio-frequency chip design in-house behind its planned satellite constellation, for an undisclosed sum. Jariet, founded in 2015 in Redondo Beach, California, designs millimeter-wave RF chips for satellite communications, electronic warfare and radar, using digital beamforming and wideband signal processing, which will be integrated across CesiumAstro’s ground, air and space offerings. The deal adds about 100 employees across US and Swiss operations.

CesiumAstro, an Austin phased-array antenna developer said in-house semiconductor design gives it tighter control across the RF signal chain and faster capability development. The acquisition supports Synchronicity, its proposed 737-satellite low-Earth-orbit network using Ku-, Ka- and V-band spectrum for enterprise and government users. It follows CesiumAstro's late-2025 purchase of AI startup Vidrovr and precedes the October 2026 launch of its first Element satellite platform.

Chinese launch company, iSpace (Beijing Interstellar Glory Space Technology Ltd.) has closed the first tranche of a planned Series E round, raising nearly 1 billion yuan / $148 million led by asset-investment arms of China's major state banks, with fundraising continuing. The proceeds fund development and mass production of the Hyperbola-3 reusable rocket, Focus-2 methane-oxygen engine capacity, launch and sea-recovery infrastructure, and heavy-lift pre-research, following a record $729 million round in February.

iSpace targets Hyperbola-3's debut, including a first-stage recovery attempt, before the end of 2026, then a STAR Market listing in the second half of 2027. The two-stage, 69-meter rocket carries 8,500 kilograms to low Earth orbit reusable, 13,400 kg expendable. iSpace reached orbit first among Chinese commercial firms in 2019 but has since seen four Hyperbola-1 failures, and now competes with Landspace, Galactic Energy, CAS Space and Space Pioneer for megaconstellation launch contracts.

Astronomers find best evidence that magnetic fields bend empty space, confirm 90-year-old quantum prediction on vacuum

Astronomers have reported the strongest evidence to date of vacuum birefringence, a quantum electrodynamics effect in which extreme magnetic fields alter the properties of empty space and change how light propagates. It is an effect in which a magnetar's (a type of neutron star with an extremely powerful magnetic field reaching tens to hundreds of billions of Teslas, as compared with about 10 for an MRI scanner) extreme magnetic field alters empty space so it bends light like a prism. Using NASA’s Imaging X‑ray Polarimetry Explorer, researchers observed unusually high X‑ray polarization from the magnetar 1E 1547‑5408 in early 2025, aligned with its magnetic field and far exceeding levels predicted by standard neutron‑star emission models.

The findings, published Aug. 5 in Nature, confirm a prediction first proposed 90 years ago, in 1936 by Heisenberg and his student Hans Euler that virtual particle pairs (such as electrons and positrons that go in and out of existence) in a vacuum respond to intense magnetic fields. The astronomers combined NASA’s IXPE (Imaging X-ray Polarimetry Explorer) telescope data with radio and X‑ray observations from the ISS, Australia’s Murriyang telescope and the South African Radio Astronomy Observatory. The X-rays were nearly three times more polarized than models predict, and aligned with the star's magnetic field — leaving vacuum birefringence, they concluded, as the only fit.

Researchers plan follow‑up studies using proposed missions such as GoSOX and improved simulations to further isolate the effect around magnetars.
