Summary
Inversion Space, founded in 2021 by Boston University students Justin Fiaschetti and Austin Briggs and backed by Y Combinator, builds reentry vehicles that park cargo in orbit and bring it down on demand, inverting the usual direction of space logistics: instead of launching goods when they are needed, the goods wait overhead and come back within an hour of the request. Its flagship vehicle, Arc, was unveiled on October 1, 2025 as a fully reusable lifting body about four feet across and eight feet tall that stores roughly 500 lb of payload on orbit for up to five years, survives reentry above Mach 20, steers more than 1,000 km of cross-range, and touches down under an autonomously guided parachute within about 50 feet of a target, needing no runway and using non-toxic propellants so crews can approach it immediately. The company has raised roughly $54 million, most of it a $44 million Series A in November 2024 co-led by Spark Capital and Adjacent with Lockheed Martin Ventures and Kindred Ventures, on top of a $71 million STRATFI award from AFRL and SpaceWERX in September 2024. Its pathfinder, the 20-inch Ray capsule, launched on SpaceX's Transporter-12 in January 2025 and validated avionics, power, propulsion, and separation, but a short circuit kept the deorbit engine from igniting, so it never flew the reentry it was built to demonstrate. Defense demand has arrived ahead of the flight record: Inversion was selected into Kratos' $1.45 billion MACH-TB 2.0 hypersonic test program in September 2025 and joined Anduril's team for the Space Force's Golden Dome space-based interceptor work in May 2026. It operates a 55,000-square-foot Los Angeles factory and a five-acre Mojave test site with about 60 employees, and the whole thesis now rests on flying Arc for the first time.
Main Products
A fully reusable lifting-body reentry vehicle, roughly four feet wide and eight feet tall, that stays on orbit as a functioning satellite for up to five years holding about 500 lb of cargo, then deorbits on command. Control flaps, attitude-control thrusters, and a deorbit engine steer it through a Mach 20-plus reentry with more than 1,000 km of cross-range, and an autonomously guided parachute puts it down within about 50 feet of a target on unprepared ground. Non-toxic propellants let crews approach it as soon as it lands, and it can also capture and deploy assets and rendezvous with other spacecraft while on orbit.
Full-scale structural development unit built, mission profile complete, dozens of drop tests flown, NASA working the thermal protection system; first orbital mission targeted 2026
The 20-inch pathfinder capsule that flew Inversion's first orbital mission on SpaceX's Transporter-12 in January 2025. It validated avionics, solar power, the propulsion system, and an in-house separation mechanism on orbit, but a short circuit prevented the deorbit engine from igniting, so the planned reentry and recovery never happened. Its flight data underpins the Arc design.

What's Next
The mission that decides whether the company has a product. Inversion has said since the October 2025 unveiling that Arc flies its first mission in 2026, which means launching the vehicle, holding it on orbit, deorbiting under control, surviving a Mach 20-plus reentry, and landing under parachute close to a target. Ray never got past the deorbit burn, so this is the first real test of the reentry stack end to end. Watch for a launch assignment and an FAA reentry license for the Arc configuration.
Fly hypersonic test payloads under MACH-TB 2.0
Inversion's selection into Kratos' MACH-TB 2.0 program gives it a paying use for reentry itself. Watch for the first task order and the first customer payload flown through hypersonic conditions on an Inversion vehicle, the point at which the reentry capability starts generating revenue independently of the cargo-delivery thesis.
Stand up an operational constellation of Arcs
CEO Justin Fiaschetti has put constellation deployment around 2028, which implies producing hundreds of vehicles a year. That is a manufacturing problem as much as an aerospace one, and the gap between one flight article and a production line is where most reentry programs stall. Watch for factory expansion beyond the current 55,000 square feet and for a multi-vehicle order from the Air Force or Space Force.
Deliver reentry hardware for Golden Dome interceptors
Under the Anduril-led space-based interceptor team named in May 2026, Inversion's maneuvering and reentry work feeds the Space Force's Golden Dome architecture, which the service wants integrated by 2028. Watch for a defined subcontract scope and any prototype flight demonstration tied to it.

Ray demonstrator returns from orbit
Target January 2025 · Resolved Jan 30, 2025
Ray launched on Transporter-12 on January 14, 2025 with an FAA reentry license in hand and successfully checked out avionics, solar power, propulsion, and separation on orbit. A short circuit in a component prevented the deorbit engine from igniting, so reentry became impossible and the capsule was never recovered. Inversion folded the flight data into Arc rather than reflying Ray.
Operations & Revenue
Inversion has one orbital flight behind it and it was a partial failure: Ray reached orbit in January 2025 and checked out its subsystems, but a short circuit stopped the deorbit burn, so the company has not yet demonstrated the one capability its entire business rests on, controlled reentry and precision landing. Arc is the vehicle that has to prove it. Hardware progress is real, with a full-scale structural development unit built, a mission profile closed, dozens of parachute drop tests run, and NASA collaborating on thermal protection, and the first Arc mission is targeted for 2026 with an operational posture that would require producing hundreds of vehicles a year by 2028. Money and demand are not the constraint: a $44 million Series A, a $71 million STRATFI award, a seat in the $1.45 billion MACH-TB 2.0 hypersonic testbed program, and a place on Anduril's Golden Dome interceptor team give it customers before it has a product. Schedule and reentry physics are the constraint, and the hypersonic testbed work is the near-term hedge that pays whether or not the on-demand cargo market appears.
Revenue Streams
Defense cargo delivery from orbit
The core proposition: constellations of Arc vehicles pre-positioned in low Earth orbit, holding cargo for allied militaries and deorbiting on request to put it anywhere on the planet in under an hour, including in denied environments where aircraft and ships cannot go. Funded so far through the $71 million AFRL and SpaceWERX STRATFI award rather than delivery revenue.
Selling reentry as a test service: an Arc coming home above Mach 20 is a reusable hypersonic testbed, and Inversion's selection into Kratos' MACH-TB 2.0 program gives it a way to bill for flights while the cargo market is still theoretical. This is the nearest-term revenue line.
Key Metrics
Timeline
Anduril names Inversion on May 5, 2026 among the partners for the Space Force's space-based interceptor prototype work under Golden Dome, alongside Impulse Space, K2 Space, Voyager Technologies, and Sandia National Laboratories, with Inversion's reentry expertise applied to the interceptor problem.
Ray launches January 14, 2025 on SpaceX's Transporter-12 rideshare and validates avionics, solar power, propulsion, and an in-house separation system on orbit. A short circuit in a component prevents the deorbit engine from igniting, so the capsule never performs the reentry it was built to demonstrate.
Kratos selects Inversion in September 2025 for MACH-TB 2.0, the Pentagon's hypersonic testbed program worth up to $1.45 billion, opening a near-term revenue line: flying test payloads through real hypersonic reentry conditions rather than waiting for the cargo-delivery market to mature.
On October 1, 2025 Inversion reveals Arc, a reusable lifting-body delivery vehicle sized to hold about 500 lb on orbit for up to five years and return it anywhere on Earth in under an hour. The company says it has already built a full-scale structural development unit, completed the first mission profile, and run dozens of drop tests, and is working with NASA on the thermal protection system.
Justin Fiaschetti and Austin Briggs leave Boston University to start Inversion around the premise that returning things from space, not launching them, is the missing half of space logistics. The company goes through Y Combinator and closes a seed round announced in November 2021.

Astroscale
Orbital Economy +1
Astroscale is the only company in the world building a business purely around servicing what is already in orbit: removing debris, deorbiting dead satellites, extending the life of working ones, refueling them, and inspecting them. Founded in Tokyo in 2013 by Nobu Okada and listed on the Tokyo Stock Exchange Growth market since June 2024 under ticker 186A, it operates across Japan, the UK, the US, France, and Israel. Its ADRAS-J spacecraft made history in 2024 as the first vehicle ever to approach and photograph a large piece of orbital debris up close, a discarded Japanese rocket upper stage, and it completed operations and began its own deorbit in March 2026. JAXA has since contracted the follow-on ADRAS-J2 for roughly 12 billion yen to go back to that same rocket body and actually remove it with a robotic arm. Alongside that flagship line Astroscale is preparing ELSA-M, billed as the world's first commercial end-of-life deorbit service and now booked on Isar Aerospace's Spectrum rocket; LEXI, a geostationary life-extension servicer; the Astroscale U.S. Refueler, which is set to perform the first refueling of a United States Space Force asset; and ISSA-J1, a 2027 mission that will inspect two retired Japanese satellites in different orbits on a single flight. The company remains deeply loss-making: for the fiscal year ended April 30, 2026 it reported 5.94 billion yen of IFRS revenue against a 9.98 billion yen operating loss, with an order backlog of 37.94 billion yen.
Blue Origin
Orbital Economy +1
Blue Origin is a privately held aerospace company founded by Jeff Bezos that develops reusable launch vehicles, rocket engines, lunar landers, in-space mobility systems, and satellite communications infrastructure. Its current programs span the New Shepard suborbital system, the New Glenn heavy-lift rocket, the BE-4 engine family that also powers ULA's Vulcan, the Blue Moon lunar lander family, the Blue Ring spacecraft platform, and the TeraWave network. The FAA closed its NG-3 mishap investigation and lifted the New Glenn grounding on May 22, 2026 - pinning the BlueBird 7 deployment failure on a cryogenic leak that froze a hydraulic line - but six days later, on May 28, a New Glenn exploded during a hotfire at Cape Canaveral's LC-36, destroying the transporter-erector at Blue Origin's only New Glenn pad. CEO Dave Limp said the rocket will fly again before year-end via a hybrid horizontal-integration/crane-erect path that skips replacing the destroyed transporter-erector, with the propellant farm, a second flight-ready booster, and three upper stages intact; on July 24, 2026 NASA and Blue Origin agreed to conduct New Glenn second-stage (GS2) hot fire testing at Stennis Space Center's B-2 stand beginning this fall while LC-36 recovers. The Blue Moon MK1 'Endurance' cargo lunar lander has completed thermal vacuum testing at NASA Johnson, but with New Glenn grounded its launch to the Moon has slipped from a fall-2026 target to early 2027. In a landmark shift after 26 years of near-total self-funding (roughly $30B cumulative), Blue Origin raised about $10B at a $130B valuation in July 2026 - its first-ever outside round, led by Coatue (~$4B) with Jeff Bezos adding ~$2B - to bankroll Limp's target cadence of roughly 100 launches a year against an estimated ~$4.8B 2026 spend.
CASC

China Aerospace Science and Technology Corporation (CASC) is the state-owned prime contractor for China's space program and the world's most prolific launch organization by missions flown. Wholly owned by the central government through SASAC, it develops and operates the Long March (Changzheng) rocket family - which flew its 650th cumulative mission on June 11, 2026 - along with the Shenzhou crewed spacecraft, Tianzhou cargo vehicles, the Tiangong space station, BeiDou navigation and GuoWang broadband satellites, the Chang'e lunar and Tianwen planetary probes, and China's strategic missiles. After a national-record 73 launches in 2025, CASC is targeting over 100 launches in 2026 amid an industry-wide national push toward ~140, debuted the partially reusable Long March 12B in June 2026, and saw its Tianwen-2 probe reach the quasi-moon asteroid Kamo'oalewa on June 7, 2026. On July 10, 2026 it made China the second nation ever to recover an orbital rocket first stage, when the new single-stick, partially reusable Long March 10B flew its maiden mission from Hainan and captured its booster in a sea-based net - a landmark step toward closing the reusability gap with SpaceX. It is preparing to fly Chang'e 7 to the lunar south pole no earlier than August 2026 while advancing the triple-core Long March 10 toward a crewed Moon landing before 2030.
Firefly Aerospace

Firefly Aerospace is a public space and defense company that launches the Alpha small-lift rocket, is co-developing the Eclipse medium-lift vehicle with Northrop Grumman, flies Blue Ghost lunar landers, and builds Elytra orbital vehicles for maneuvering, communications, imaging, and other cislunar services. After becoming the first commercial company to complete a fully successful Moon landing, Firefly expanded further into defense software and data systems through its SciTec acquisition, which won a U.S. Space Force Space-Based Interceptor OTA agreement in May 2026 and a $5.5M Air Force CBC2 data-fusion option in June 2026 as part of the Golden Dome architecture. Q1 2026 revenue was $80.9M against $1.3B of backlog, Firefly doubled its Cedar Park campus to 144,000 sq ft to industrialize Blue Ghost and Elytra production, closed a 12M-share follow-on at $48/share on June 1, 2026, and - per June 23, 2026 Reuters reporting - is set to secure a ~$110M EXIM loan to fund further Texas production expansion as it prepares the first full Alpha Block II flight (Flight 8) for late summer 2026. In July 2026 Firefly also won a $13M NASA JPL subcontract - the first out of its new Gloworks innovation lab - to build the aeroshell for NASA's SkyFall Mars helicopter mission, extending it into planetary entry-descent-and-landing hardware.
Impulse Space
Orbital Economy +1
Impulse Space builds the vehicles that move payloads once a rocket has done its job, a business the company calls in-space mobility. It was founded in 2021 by Tom Mueller, SpaceX's founding propulsion engineer and the architect of the Merlin engine, and sells two vehicles: Mira, a highly maneuverable 300 kg-class orbital transfer and hosting spacecraft that has flown three missions since November 2023, and Helios, a high-energy kick stage powered by the 67 kN Deneb methalox engine that is designed to carry a payload from low Earth orbit to geostationary orbit in under a day rather than the months an electric tug needs. In July 2026 the U.S. Space Force awarded Impulse a National Security Space Launch Phase 3 Lane 1 contract, making it the first upper-stage provider ever to hold prime status in a program historically reserved for rocket companies, and in June 2026 the company raised a $500 million Series D that took total funding past $1 billion. Mira has already proven the harder operational trick: in December 2025 two Impulse Mira spacecraft performed a fully autonomous rendezvous in low Earth orbit with Starfish Space's Remora payload aboard. Helios is now targeted for its inaugural flight in 2027, and a third product line, the in-house Electra electric propulsion system, debuts alongside it.
Rocket Lab
Orbital Economy +1
Rocket Lab is an end-to-end space company spanning launch, hypersonic test launch, spacecraft, payloads, satellite components, and now laser optical communications and space robotics. Electron remains the second most frequently launched U.S. rocket - Rocket Lab reached 92 missions with the July 1, 2026 'Grain Goddess' launch of iQPS' QPS-SAR-13 radar satellite, putting it on track for a record year and its 100th launch - and Rocket Lab is developing the medium-lift Neutron rocket for constellation, national-security, and exploration missions, with first launch still targeted for Q4 2026. The company posted record Q1 2026 revenue of $200.3M and backlog above $2.2B, completed the $155.3M Mynaric acquisition in April 2026 to add laser comms and a European footprint, and closed the Motiv Space Systems robotics acquisition in May 2026 to bring Mars-proven robotics in-house. On May 27, 2026 Rocket Lab cleared the System Requirements Review for the Space Development Agency's $816M Tracking Layer Tranche 3 missile-defense constellation, taking total SDA awards above $1.3B, and on June 22, 2026 the company joined the Nasdaq-100 Index. On June 29, 2026 Rocket Lab announced its largest-ever deal - an agreement to acquire satellite-communications operator Iridium Communications for about $8B in cash and stock ($54.00/share, roughly half cash and half Rocket Lab stock), adding an operational 66-satellite L-band constellation, ~2.55M subscribers, $871M of 2025 revenue, and globally harmonized spectrum, with the transaction expected to close in mid-2027.
