{{First_Name|Explorer}}, welcome back!🚀

Last week was a well rounded one: plenty of new developments in science, commerce and defense. Having trouble with links? Click the link below to read the unclipped publication. ↓

I’ll let you dive in.

NASA and University of Alabama in Huntsville researchers are developing a plasma‑based “laundry gun” to sanitize fabrics and soft surfaces during long‑duration missions, aiming to reduce microbial loads without water or chemical cleaners. The prototype, built with NASA’s Marshall Space Flight Center, uses cold plasma generated from air, helium and water vapor to create reactive oxygen species that damage bacterial cell membranes.

Early tests show more than 75% reduction in spores on fabric, though the pen‑sized device treats only small areas and does not remove stains. Engineers are designing larger handheld units and ozone‑removal systems. The work grew from planetary‑protection research and could support broader life‑support functions, including crop growth, waste processing and suit sterilization for lunar and Mars expeditions.

NASA has funded an early-stage concept for small, silent flying robots to explore the caves of Saturn's moon Titan, under its Innovative Advanced Concepts program. The project, called SPARK, would deploy lighter-than-air "aerobots" from a larger spacecraft to navigate karst terrain (sinkholes and caves) that rovers cannot cross. The vehicles would use solid-state electrohydrodynamic (EHD) ion thrusters, or atmospheric ion thrusters, which Titan's dense, cold atmosphere makes far more viable than on Earth. The design expects over 100 times the power savings, avoids the cryogenic-heating rotors require, and minimizes downwash in fragile hydrocarbon cave environments, that could disturb scientifically important hydrocarbon layers.

Led by the University of Hawaii's Daniel Drew with JPL collaborators, Solid‑state Propulsion for Autonomous Reconnaissance of Karst or SPARK begins a nine-month Phase 1 of feasibility studies and modeling. It is unclear whether it could be ready for NASA's Dragonfly Titan mission, targeting a 2028 launch. The team will model EHD performance in Titan’s dense, cold atmosphere, conduct feasibility experiments, and complete subsystem trade studies toward a Phase 2 prototype. Drew’s group, joined by collaborators from JPL and the Blue Marble Space Institute of Science, has previously demonstrated micro‑scale ion‑propelled flyers and aims to assess broader applications such as balloon station‑keeping and hopper trajectory control in favorable atmospheres.

A study of 52 astronauts offers biochemical evidence for why spaceflight causes constipation: microgravity appears to slow food through the intestines, prompting gut bacteria to ferment protein rather than fiber. Researchers from the University of Copenhagen and NASA analyzed 488 blood-plasma samples from crew who spent two to nine months on the ISS between 2006 and 2018, using non-targeted metabolomics (measuring all circulating small molecules rather than hunting for specific ones). About 40 compounds changed in orbit, including protein-fermentation metabolites that rose in space and subsided within days of return. Diet, including caffeine and fish intake, explained less than a third of the shift.

Normally colon bacteria ferment fiber, but when slowed transit depletes it they break down protein instead, producing byproducts like ammonia and hydrogen sulfide linked to kidney damage and possible effects on mood and focus. The researchers note the results were unusually clear for a metabolite study. Pooling 52 astronauts across many missions and years cut the individual variability that normally muddies such work. They suggest countermeasures such as slowly fermented fiber or prebiotics, relevant to long Moon and Mars missions and to bedridden patients on Earth, who face similar constipation, part of a lineage of microgravity research, like bone-loss studies, that informs medicine on the ground. The research was published in the journal Nature Communications.

NASA astronaut Anil Menon and ESA astronaut Sophie Adenot removed a failed Space-to-Ground antenna during a 6-hour, 23-minute spacewalk outside the International Space Station on Aug. 18, but ran out of time to install its replacement, deferring that work to a future outing. This Extra-Vehicular Activity or EVA marked the 282nd ISS spacewalk and Adenot’s first, making her the first French woman to perform an EVA. Menon logged his second spacewalk, bringing his cumulative time to 12 hours, 50 minutes.

The antenna had been unable to track NASA's data-relay satellites since November; a second antenna has maintained high-rate communications with Mission Control Houston. The crew removed the dish but hit delays disconnecting electrical cables and loosening gimbal bolts, so controllers had them tie the unit down on the truss rather than fit the replacement. Mission planners are assessing whether to add the antenna installation to the next scheduled spacewalk on Aug. 25, which will also involve Canadarm2 operations and potential get‑ahead tasks.

NASA has called off the effort to save its Swift gamma-ray observatory after Katalyst Space's LINK rescue spacecraft could not overcome its own attitude-control problems, the agency and company said Aug. 19–20. NASA now expects Swift to reenter the atmosphere later this year. Launched in 2004 with a two-year design life, Swift has operated for 21 years, studying gamma-ray bursts, among the universe's most energetic events, and rapidly slewing to observe supernovae, fast radio bursts and other transient phenomena. It remained scientifically productive but, lacking thrusters of its own, could not counter an orbital decay accelerated by heightened solar activity.

LINK, launched July 3, 2026, entered a multi-axis spin about three weeks in after losing two of three reaction wheels, Controllers slowed the spin and uploaded new flight software, and by mid-August the fix had restored enough control to raise hopes of rendezvous and capture. NASA and Katalyst ultimately concluded LINK could not safely grapple and boost the observatory. The mission, however, is not fully over as LINK will still attempt rendezvous and proximity operations near Swift to demonstrate servicing techniques for future missions, and Katalyst frames the salvaged objectives as a repeatable playbook for satellite servicing. NASA awarded the roughly $30 million contract in 2025 on an under-a-year timeline, always describing it as high-risk.

Astronomers have reported the discovery of S301, the fastest known star in the Milky Way (closest‑known) orbiting Sagittarius A*, offering a new way to probe the Milky Way’s central black hole. Detected with ESO’s Very Large Telescope Interferometer, S301 reaches 25,000 km/s, over 8% the speed of light and completes an orbit in 8.7 years, approaching within roughly the Sun–Saturn distance.

Its extreme proximity makes S301 the first star capable of enabling a direct measurement of the black hole’s spin, a key prediction of general relativity. Researchers traced its orbit back to 2017 and expect its next close passage in 2031, with GRAVITY+ and ESO’s Extremely Large Telescope providing the precision needed to test spacetime effects near Sagittarius A*.

A new study published Aug. 19 in Science Advances finds that several bacteria and fungi commonly associated with crewed missions could survive on the lunar surface in a cryptobiotic state, i.e., a state of suspended animation, particularly within shadowed terrain at the poles. Researchers compared microbial survivability data with ultraviolet and thermal maps and concluded that hills, valleys and permanently shadowed regions may provide sufficient shelter for microbes to persist without growing.

The work suggests even small disturbances, such as rover tracks or bootprints, could create micro‑habitats, highlighting planetary‑protection concerns ahead of Artemis III’s planned south‑pole landing. The team also noted that ancient Earth rocks ejected by impacts could have delivered microbes to the Moon. Future experiments will test broader microbial resilience as NASA evaluates contamination risks during polar exploration.

China is preparing to launch Chang’e‑7, a multi‑spacecraft mission aimed at conducting the country’s most detailed investigation of the lunar south pole to date, including a search for subsurface water‑ice. The launch, however, originally planned for Aug. 23-24, has been postponed and a new target date has not yet been confirmed.

The complex robotic mission combines an orbiter, lander, rover, hopper and multiple international payloads aimed at surveying the lunar south pole and advancing plans for a crewed landing by 2030. A Long March 5 Y14 rocket rolled out at Wenchang on Aug. 19, with airspace notices indicating an evening launch window on Aug. 23 ET. The mission will insert the craft into translunar orbit, arriving at the Moon roughly five days later. The orbiter will spend several months mapping and imaging candidate landing zones near Shackleton Crater, with a precision landing attempt expected months afterward.

The lander will target a very small, pecific landing zone, an area less than 100 meters across, and located on higher ground near the lunar south pole, offering extended sunlight and access to permanently shadowed regions. The mission’s hopper will “jump” between sunlit and shadowed terrain to search for water ice, supported by a new landmark‑image navigation system. It will fly into dark craters to analyze frost and drill up to a meter deep for “dirty ice,” heating samples to release volatiles for mass‑spectrometer analysis, including hydrogen‑isotope ratios.

Chang’e‑7’s spacecraft and the Queqiao‑2 relay, China’s dedicated lunar communications relay satellite for south‑pole exploration, carry seismographs, cameras, magnetometers, spectrometers and penetrating radar. Scientists highlight the mission’s potential to characterize volatiles both at the surface and in the shallow subsurface, complementing NASA’s VIPER rover and ESA’s PROSPECT drill, which are also targeting the region later this decade.

Chang’e‑7 carries instruments from Russia, Italy, Switzerland, Thailand, Bahrain, Egypt and Hong Kong, including ILOA’s (International Lunar Observatory Association), ILO‑C (International Lunar Observatory - China) wide‑field optical camera for the first color astronomical imaging from the Moon. The mission precedes Chang’e‑8 in 2028, which will test in‑situ construction using lunar soil.

The China Manned Space Agency announced that the mission did not meet launch conditions due to disruptions from Tropical Storm Narra and could not proceed during the planned 2026 launch window.

The European Union has sanctioned three executives tied to Russia's military space sector, part of a widening effort to target the industry over its role in the war in Ukraine. New individual sanctions designated Viktor Ivanov, head of Roscosmos subsidiary NII TP for his role in developing the Kasatka‑R synthetic aperture radar system used by the Russian military. Under the measures, Ivanov's EU-held assets are frozen, EU persons and entities are barred from providing him funds, and he is prohibited from entering or transiting the bloc. An EU spokesperson said the designations signal that personal involvement in the war carries individual consequences, citing space technology's growing role in reconnaissance, targeting and communications. The move extends earlier sanctions on NII TP itself, listed June 15, nearly three years after US sanctions in 2023.

The EU also sanctioned Sergey Bashkov, director of Irz‑Svyaz, a key producer of GPS and GLONASS navigation receivers, and Aleksandr Dyukarev, head of Krasnoyarsk Machine‑Building Plant, which manufactures RS‑28 Sarmat ICBMs and rocket modules.

EU officials framed the individual designations as a way to extend pressure beyond the firms' limited commercial exposure to the people running them, reaching organizations that have little EU business to freeze. The spokesperson said this maps the wider ecosystem around Russia's military-industrial complex, though the EU would not explain why it moved against Ivanov personally less than two months after listing NII TP, saying only that sanctions are "dynamic" and member-state discussions remain confidential.

The Trump administration’s fiscal 2027 defense budget proposal would more than double Space Force spending, according to a new analysis from The Aerospace Corporation’s Center for Space Policy and Strategy. The proposed $71.3 billion request, a 120% increase over 2026 in the Space Force's fiscal 2027 budget is concentrated in a few missions such as moving-target tracking, missile warning, command-and-control and classified programs, rather than spread across the service, the analysis found.

The largest percentage rise for any military service since 1952, includes $59.2 billion in base funding and $12.1 billion contingent on a separate reconciliation package, so the outcome could fall anywhere between. Author Robert Wilson found more than three-quarters of the increase in those select areas. The largest line item is space-based air moving-target indication at $7.9 billion, followed by the Space Data Network, a proliferated LEO architecture supporting high‑volume data transport that budget documents say would also support space-based interceptors. Both were funded under Golden Dome in 2026 but relabeled "Space Superiority" for 2027, which is a change Wilson called budget structure, not mission, since both still support missile defense.

Golden Dome money, however, sits separately: the administration seeks $17.1 billion for it through reconciliation, including $4.5 billion for space, outside the Space Force request. Missile-warning funding in low Earth orbit rose $1.9 billion to $3.6 billion, with a medium-Earth-orbit (MEO) companion more than doubling to $1.4 billion. House appropriators backed about 94% of the base request, and a projected $69.6 billion in 2028 suggests the increase is meant to endure.

20 August, 2026

President Trump signed a new National Space Transportation Policy on Aug. 20, the first update since 2013, setting a goal of supporting at least 1,000 launches and reentries a year from US facilities by 2030, up from just under 200 US launches in 2025. The policy emphasizes infrastructure over vehicles, directing the Pentagon, NASA and Transportation Department to identify sites for new launch facilities within 180 days and the Interior Department to find federal land for a new reentry site within 90 days, addressing a shortage that has pushed firms like Varda to reenter in Australia.

It calls for co-development with private operators, integrating launch corridors into air-traffic control, developing scheduling criteria to maximize federal ranges, and an Office of Science and Technology Policy (OSTP) industrial-base strategy within 180 days. For government payloads, it directs NASA and the Pentagon to maintain multiple launch providers and adaptable interfaces letting payloads move between rockets, and supports responsive launch, building on the Pentagon's push for 48-hour access demonstrated by Victus Nox (27 hours' notice, 2023) and Victus Haze (17 hours, June 2026). It reiterates US-vehicle and commercial-service preferences, directs NASA toward commercial lunar-logistics and eventual Mars-transport architectures, and builds on Trump's August 2025 commercial-space order and the FAA's proposed rule waiving 13 environmental laws.

22 August, 2026

The U.S. Federal Aviation Administration (FAA) moved immediately to implement elements of the White House’s updated National Space Transportation Policy, issuing a request for information on potential new spaceport locations and the designation of “priority airspace” for launch corridors. The RFI, to open a 60‑day comment period, supports policy goals of scaling U.S. launch and reentry activity to 1,000 annually by 2030 and 10,000 by 2035, a figure neither the FAA nor the Department of Transportation had raised before and one that dwarfs the FAA's own forecast of at most 498 space operations in fiscal 2035.

The RFI seeks input on criteria for domestic and international spaceports (siting criteria, island and overseas spaceports), reasons for underutilization of existing sites, and lessons from abandoned projects such as Spaceport Camden. It also requests feedback on defining and managing critical launch corridors.

Industry groups broadly endorsed the policy’s infrastructure ambitions, while noting privately that funding mechanisms (which could run into billions) for large‑scale spaceport modernization remain unclear.

DIU and SDA picked D-Orbit, Firefly and Katalyst to study satellite deorbiting; the NRO moved HawkEye 360 to operational RF intelligence; and SpaceWERX gave 11 firms STRATFI funding worth up to $562.5 million.

16 August, 2026

The United States Defense Innovation Unit (DIU) and Space Development Agency (SDA) selected D‑Orbit USA, Firefly Aerospace and Katalyst Space to study commercial "deorbit-as-a-service" options, exploring whether disposal of aging spacecraft can be bought from operators rather than built as a government capability. Through the undisclosed-value contracts, Pentagon wants them to begin design and risk‑reduction work on commercial deorbit‑as‑a‑service concepts, expanding its effort to procure satellite disposal from industry rather than rely on government‑built systems. The companies will study approaches for autonomously rendezvousing with, capturing and deorbiting aging spacecraft not designed for servicing. Firms will begin preliminary design before SDA and DIU choose one for an on-orbit demonstration.

The awards build on SDA’s 2024 feasibility studies and Starfish Space’s $52.5 million contract to deorbit up to seven satellites. Firefly proposes using its Elytra maneuvering spacecraft, Katalyst is preparing its Link servicer following recovery from attitude‑control issues (launched July 3 to boost NASA's Swift telescope), and D‑Orbit, a 2024 US-Italian venture, brings logistics experience from its Italian parent. DIU and SDA said viable services must reliably locate, capture and dispose of non‑cooperative satellites at commercially acceptable cost.

17 August, 2026

The U.S. National Reconnaissance Office (NRO) has awarded HawkEye 360 an operational contract for commercial radio-frequency intelligence, moving the company from a multiyear evaluation into supplying US intelligence and defense agencies. The undisclosed award, under the NRO's Commercial Radio Frequency Capabilities Augmentation program, follows a three-phase effort begun in 2022 that evaluated six firms through modeling and on-orbit demonstrations to assess how commercial RF satellites can supplement government systems by detecting and geolocating electronic emissions. The progarm lets the NRO scale purchases as needs change, mirroring how it brought commercial optical and synthetic-aperture-radar imagery into its intelligence architecture.

HawkEye operates more than 30 satellites in three-satellite clusters in LEO, that detect and geolocate emitters like radars and communications by combining measurements across spacecraft, and is targeting roughly 10-minute revisit and latency within two to three years using added satellites and hosted payloads. Demand is expanding abroad as the firm, public since May, reported record international revenue of $21 million in the second quarter, up 134% and about 42% of its $49.8 million total, and has disclosed more than $100 million in recent international awards, including a European electronic-warfare program and a multiyear Indian Navy contract.

20 August, 2026

SpaceWERX, the Space Force's innovation arm, selected 11 companies for its latest Strategic Funding Increase round or STRATFI public-private funding agreements meant to move space technologies from prototype toward operational use. The funding is meant to advance technologies, transitioning from SBIR Phase 2 prototypes toward operational Space Force use. The agreements, announced Aug. 20, are expected to draw $562.5 million in combined government and private funding, including $245 million in federal contributions.

The firms are Agile Space Industries, Antares Nuclear, EO Solutions, Hydrosat, Kall Morris, Method Security, Muon Space, Scout Space, Sedaro, Star Catcher Industries and ThinkOrbital, spanning propulsion, nuclear microreactors, space-domain awareness, thermal imaging, orbital logistics, cyber, satellite constellations, simulation, power beaming and in-orbit servicing, evidence of a broad demand for dual‑use space capabilities. The selections are not yet finalized and the firms will now negotiate milestones and demonstrate military applicability before final contract awards.

STRATFI agreements can reach $60 million per project and require matching investment from operational customers and private capital. Director Arthur Grijalva said STRATFI signals demand to industry and investors by requiring an operational customer and outside capital alongside government funds.

A US Air Force C-17 bound for Antarctica turned back over the southern Indian Ocean on Aug. 18 after New Zealand aviation authorities relayed a Russian notice warning of “space activity, potentially hazardous to aviation.” The transport left Christchurch in New Zealand for McMurdo Station in Antarctica and reversed course about two hours in. New Zealand's Civil Aviation Authority said the Russian Air Traffic Management Corporation had flagged a warning en route. The activity was not identified, and the U.S. Air Force has not commented.

The nature of the hazard remains unclear, though the U.S. FAA had issued an Aug. 10 Notice to Air Missions or NOTAM for the Melbourne Flight Information Region citing “possible debris” from Russian aerospace activities beginning Aug. 14. The FAA notice had warned of possible debris over Australian and Indian Ocean airspace. Falling rocket debris has forced airspace closures before, though such notices can also accompany planned weapons tests, which are usually announced well in advance.

The incident follows recent airspace closures linked to uncontrolled reentries and debris events, including China’s Long March 5B in 2022 and SpaceX’s Starship in early 2025. Russia’s notice could also reflect high‑altitude weapons testing, though such activities are typically announced well in advance.

JPMorganChase's Strategic Investment Group, Andreessen Horowitz and Carlyle funds co-led the round, valuing the the four-year-old startup at $13 billion as it scales the low-cost Blackbeard hypersonic missile production in New Mexico.

19 August, 2026

Castelion, a defense-tech startup mass-producing lower-cost hypersonic weapons, has raised more than $1 billion, valuing the four-year-old firm at $13 billion, to scale production of its Blackbeard hypersonic strike missile and accelerate development of additional offensive and defensive systems. The Series C combines $800 million in equity, co-led by JPMorganChase's Strategic Investment Group, Andreessen Horowitz and Carlyle funds, with a $250 million credit facility. The money will help scale production of Blackbeard at a New Mexico complex, and work on a longer‑range precision weapon and air‑ and missile‑defense systems.

Castelion, founded by three former SpaceX executives, applies SpaceX's vertical integration and high-rate manufacturing to missiles, and has secured more than $500 million in U.S. military contracts over 18 months, with the Navy advancing integration and early operational capability. The Navy has ordered 50 pre-production Blackbeards and a Pentagon framework agreement envisions production of 500 missiles annually after testing, with Blackbeard targeted to cost about $384,000 per round, against millions for existing hypersonic weapons.

HEO is partnering with Planet to grow satellite-inspection capacity in orbit, will use SkySat to image other spacecraft, Firefly will fly Zeno Power's radioisotope unit to survive the lunar night, and Portal Space Systems bought a Falcon 9 launch, reselling rideshare capacity through Maverick Space Systems.

17 August, 2026

HEO, the Australian firm that images spacecraft from orbit, has signed an agreement to task Planet's high-resolution SkySat satellites for non-Earth imaging (NEI) when they aren't observing Earth, the companies announced Aug. 17 without disclosing terms. The deal gives HEO more than 50 orbital sensors, mostly from Earth-observation operators, to photograph other space objects. SkySat imagery will initially reach only HEO's US government customers because of licensing, though the partnership could later extend to Planet's Pelican and Dove satellites and commercial buyers.

CEO Will Crowe, who estimated 90% of HEO's business is government, said the approach needs diverse sensors and orbits rather than large dedicated satellites. Crowe cited growing commercial interest in non-Earth imaging, pointing to its use in distinguishing satellites deployed together in rideshare clusters, where operators need to identify which spacecraft is which. In another case, NEI imagery of a malfunctioning SpaceX Starlink satellite showed it was tumbling but had not broken apart.

HEO separately acquired its first satellite, Continuum-1, a repurposed Satellogic spacecraft, this year, shifting it from on-request tasking toward continuous monitoring, and plans to demonstrate proximity operations near a defunct rocket body.

19 August, 2026

Firefly Aerospace will carry a Zeno Power radioisotope heating unit (RHU) on a 2028 Blue Ghost lunar lander to test whether payloads can survive the lunar night. Zeno’s self‑contained “Survive‑the‑Night” package uses an americium‑241 radioisotope heating device producing 5 watts of thermal energy, enabling the payload to maintain communications and core subsystems, through the two‑week lunar night, at temperatures that can fall to –170 °C. Success for the unit, itself about the size of a silver dollar, means pinging back after five days of darkness. The demonstration meets a NASA incentive under a June CLPS task order, as surviving multiple lunar days becomes central to its Moon Base plans.

It will be Zeno's first spaceflight and the first commercial radioisotope power source of its class, following City Labs' July launch of the first commercially nuclear-powered satellite. Zeno is scaling RHU production and developing Stirling‑based power systems amid anticipated demand for future lunar missions, betting on a market spanning NASA, industry and international partners. Firefly is evaluating broader integration of RHUs on later landers. Intuitive Machines is also pursuing the same $15 million incentive and plans an americium‑241 RHU demonstration on its 2028 CLPS mission, contingent on NASA indemnification for nuclear payloads.

20 August, 2026

Maneuverable spacecraft developer, Portal Space Systems has bought a 2028 Falcon 9 launch for its first Supernova spacecraft and will resell excess capacity as rideshare, the company said Aug. 20. The mission, Motus Via Sol, primarily tests Supernova, which uses solar thermal propulsion for high thrust and up to 6 kilometers per second of delta-v.

Portal is partnering with launch aggregator Maverick Space Systems to sell secondary capacity for ESPA-class and larger "cake-topper" satellites (a medium-sized spacecraft mounted on the very top of a rocket's payload stack during a shared rideshare launch), with Supernova's maneuverability allowing orbit changes to place them. The move responds to operators scrambling for rides amid reports SpaceX will stop taking rideshare reservations beyond late 2028 or early 2029.

Separately, Portal's first spacecraft, the ESPA-class Starburst-1, launches in October on SpaceX's Bandwagon-5; the company raised $50 million in April and is expanding its Washington production facility.

3 August, 2026

Landspace landed the first stage of its Zhuque-3 rocket on Aug. 18 after its second launch from the Jiuquan center, becoming the first Chinese company to recover an orbital‑class booster and, globally, the third entity after SpaceX and Blue Origin to propulsively recover an orbital booster on legs. The methalox vehicle separated 137 seconds into flight, and touched down 390 kilometers downrange in Gansu Province after a powered descent. The upper stage delivered the Honghu‑03 satellite, built by Landspace satellite-manufacturing affiliate Hongqing Technology, which raised more than $191 million last month.

It follows a failed recovery on Zhuque-3's December 2025 debut, after which Landspace cut the engines used in the landing burn, added a predicted-landing-point safety system and improved thermal protection. The methane-fueled, 66-meter rocket lofts up to 18,300 kilograms reusable, comparable to Falcon 9.

Landspace said it will attempt a reflight of the recovered Zhuque‑3 first stage within six months. Landspace said it now moves from recovery verification to engineering-scale reuse, relevant to its pending STAR Market IPO and to China's Guowang and Thousand Sails (or Qianfan) megaconstellations, with Landspace targeting 20‑flight reusability as China’s commercial sector accelerates work on reusable launch systems.

Landspace's success puts it ahead of a crowded field of Chinese firms developing reusable first stages, including state-owned China Aerospace Science and Technology Corporation (CASC) whose Long March 12A also failed its debut landing, and commercial rivals CAS Space, Deep Blue Aerospace, Galactic Energy, iSpace, Orienspace and Space Pioneer.

Muon Space raised $250 million for larger satellites and China's StarRF an undisclosed round for radio-frequency sensing, spanning manufacturing, compute and RF intelligence. Starcloud $250 million for orbital data centers with Nvidia backing.

20 August, 2026

Muon Space raised $250 million in a Series C round led by Eclipse Capital, accelerating the California manufacturer’s expansion into larger spacecraft and high‑performance constellations from small satellites. The funding reportedly values the five‑year‑old company at $1.5 billion, adding to a growing group of U.S. satellite‑manufacturing “unicorns.” The five-year-old firm has deployed 11 satellites, has more than 50 in development, 13 booked to launch within a year, and recently opened a San Jose plant designed to build up to 500 satellites annually by 2027, tenfold its prior capacity. Its three launches this year are for a wildfire‑monitoring system with Earth Fire Alliance.

Its craft have been 200 kilograms or smaller, but it plans a 500-kilogram MuSat XL for Hubble Network next year and a Starship-class Condor-Ultra, aimed at orbital data-centers, in 2028. The round brings total equity funding above $386 million and supports further vertical integration, following California peers Apex and K2, which raised a combined $700 million.

Muon distinguishes its "Mission Foundry" model from rivals by starting with a customer's mission requirements rather than a predefined bus, keeping 95% of production in-house after last year's acquisition of propulsion startup Starlight Engines. President Greg Smirin cast competitors expanding from bus-building toward broader mission provision, a reference to Apex, as validation of Muon's full-stack approach.

21 August, 2026

StarRF, a Tianjin, China-based startup developing a low Earth orbit constellation to detect and geolocate radio‑frequency emissions, has closed an undisclosed Pre-A+ round led by Shandong state-owned investor Luxin Venture Capital, with participation from Tianqi Capital, Haitang Fund and existing investor Junyuan Capital. Founded in November 2023, StarRF is building its "Diting" low-Earth-orbit constellation, to monitor electromagnetic activity over land and sea, for spectrum management, maritime, public-security and defense uses, developing proprietary RF reception, demodulation, analysis and geolocation technology.

Junyuan Capital said StarRF will employ three‑satellite formation flying for RF data collection, echoing techniques used by China’s Yaogan triplets and U.S. NOSS satellites. The model also places it alongside BAE's Azalea and Unseenlabs, and investors have dubbed it "China's HawkEye 360" though StarRF has not disclosed customers or launch timelines. No investment came from state giants CASC or CASIC, suggesting regional industrial policy is driving StarRF as Beijing widens support for space-based RF sensing.

21 August, 2026

Starcloud raised $250 million in a Series A extension to accelerate development of its orbital data‑center constellation, adding Nvidia and Cisco as new investors and doubling its valuation to $2.3 billion. The funding, ed by Manhattan West brings total capital raised to $450 million since 2024 and supports manufacturing expansion, launch procurement and joint engineering work with Nvidia, whose new Space‑1 Vera Rubin Module is designed to deliver up to 25× the AI compute of the H100 GPU flown on Starcloud‑1, first satellite, launched by SpaceX in November 2025.

Starcloud plans to launch the 450‑kilogram Starcloud‑2 (will generate roughly 100 times more power) on a Falcon 9 rideshare in January 2027, ahead of a three‑ton, 200‑kilowatt‑class Starcloud‑3 and a proposed 88,000‑satellite constellation. Those plans lean on SpaceX's Starship, which is also central to SpaceX's own million-satellite compute, Starmind constellation using Nvidia GPUs after its xAI acquisition. Nvidia held about $21 billion in SpaceX shares as of June 30. The round also comes amid tightening launch availability and growing competition, as Cowboy Space pursues its own orbital‑compute upper‑stage architecture.
