Good orbit, reader

On today's signal, we lead with Artemis IV's Cooling Suit Revealed and also cover Falcon B1067 targets Record 35th Flight. You'll find more across Business, Science, and Policy & Defense.

Axiom Space and Prada have unveiled the Liquid Cooling and Ventilation Garment, the base layer astronauts will wear inside the AxEMU spacesuit during Artemis IV's planned 2028 lunar surface mission. The garment circulates cold water through embedded tubes to pull heat away from the body, and unlike older NASA cooling suits, it includes a backup system if the primary loop fails. It also manages ventilation, routing fresh oxygen to the helmet and directing exhaled CO2 to a scrubber. Axiom and Prada previously revealed the outer AxEMU suit design; the LCVG fills in the picture of what the full system looks like from skin outward. Artemis IV is currently planned as the first crewed lunar landing under the Artemis program.

Using JWST's NIRSpec instrument at 10-parsec resolution, researchers have mapped the inner 618 by 618 parsecs of NGC 4696, the central galaxy of the Centaurus cluster, and found a rotating circumnuclear disk directly connected to the galaxy's vast filamentary network. That connection closes a long-standing gap in AGN feedback models: gas cools from the hot cluster atmosphere, condenses into filaments spanning tens of kiloparsecs, loses angular momentum, and funnels into the disk before accreting onto the black hole. Magnetohydrodynamic simulations reproduce the observed structure, lending the mechanism physical grounding. A matching disk structure in NGC 1275, the Perseus cluster's central galaxy, suggests this filament-to-disk pathway is a general feature of how massive galaxies self-regulate star formation through their central black holes.

UK startup NewOrbit Space closed an $18.5 million Series A, led by Voyager Ventures, to fund its first VLEO mission and open a satellite production facility in Reading, England. Very low Earth orbit, roughly 200 to 300 kilometers altitude, offers sharper imagery and faster data links than conventional orbits, but sustained operations there require entirely redesigned satellites to survive aerodynamic drag, atomic oxygen erosion, and attitude control problems that standard hardware cannot handle. NewOrbit is developing its own propulsion, electronics, and thermal systems to address those constraints. The company plans a first commercial flight in 2028 and aims to scale its production facility from 10 satellites per year to several per week, positioning it as Europe's primary dedicated VLEO manufacturing site.

SpaceX is targeting a Monday morning launch of 29 Starlink satellites from Cape Canaveral's SLC-40, with booster B1067 set to extend its own record as the most-flown Falcon 9 first stage. Liftoff is scheduled for 6:13 a.m. EDT, with a 90% weather go at window open, though thickening mid-level clouds could reduce that to 75% later in the window. Seven Falcon boosters have now surpassed 25 flights, and SpaceX's IPO prospectus notes the company has engineered the design for up to 40 flights per booster, though it accounts for a useful life of 25 due to Starship transition plans and government contract restrictions that bar heavily flown boosters on certain missions.

Upcoming Launches

Luxembourg-based OQ Technology has partnered with Telefonica Germany to demonstrate two-way messaging and voice calls between a single LEO satellite and unmodified smartphones, using the carrier's 2.6 GHz cellular spectrum. The trial, planned for northeastern Germany in the first half of 2027, would test short communications sessions including emergency voice calls beyond terrestrial coverage. SpaceX is already advancing direct-to-device service across Europe through a rival partnership with Deutsche Telekom, making the test partly a proof-of-concept for European-controlled satellite connectivity built on open standards and licensed spectrum rather than U.S.-operated infrastructure.

A SpaceNews analysis counts 30 privately held space companies now valued at $1 billion or more, with roughly two-thirds reaching that threshold since the start of 2025. More than half of those recent unicorns were founded within the last five years, pointing to a sharp compression in the time it takes new space ventures to attract major capital. The full breakdown of which companies qualify and which markets are driving the surge sits behind a paywall, but the headline figures suggest investor appetite for space startups has intensified considerably rather than cooled after the post-2021 funding pullback.

China's Einstein Probe telescope detected EP250827b, a soft X-ray flash lasting over 1,000. The supernova's optical light curve shows two peaks with a 20-day plateau between them, which the research team attributes to a long-lived magnetar injecting energy into the explosion after stellar collapse. Magnetically driven winds from the magnetar and a surrounding accretion disk broke out at roughly 35% the speed of light, generating the X-ray emission. No radio signal was detected, ruling out a powerful on-axis jet and distinguishing this event from typical long gamma-ray bursts.

A newly identified mass feature in the binary black hole population, centered around 63.3 solar masses, is improving gravitational-wave measurements of the Hubble constant. Researchers used 142 events from LIGO-Virgo-KAGRA's GWTC-4.0 catalog to run joint estimates of cosmological and population parameters, cutting uncertainty by roughly 30–36% compared to prior standard-siren results. The key finding is that heavy black holes, previously underweighted in population models, act as an additional calibration anchor for cosmic distance measurements. As GWTC-4.0 analysis continues, this mass-scale feature may become a standard input for gravitational-wave cosmology.

ESA and the European Bank for Reconstruction and Development signed a letter of intent at the EBRD's annual meeting in Riga, formalizing plans to integrate Earth observation data into the bank's development and impact finance operations. The partnership follows roughly two years of pilot work, including involvement in the EBRD's Green Cities programme. Under the agreement, the two organizations plan to apply satellite data across the full project lifecycle, from research and product development through monitoring and impact assessment, covering sectors like climate, infrastructure, and agriculture. No binding commitments or funding figures were announced.
