Which space logistics companies can move payloads between orbits or service satellites?

Yes. The market is splitting into orbital transportation/tugs (moving spacecraft or payloads between orbits) and in-space servicing (rendezvous, docking, refueling, inspection, repair, life extension, or disposal). Some companies do both.

Leading companies

If you're specifically looking for "space trucking"

I'd divide them this way:

Already demonstrated orbital transportation

• D-Orbit — probably one of the clearest examples of a commercial orbital "delivery truck."
• Exotrail
• Momentus
• Atomos Space

NASA's current small-spacecraft survey lists D-Orbit, Exotrail, Atomos and other commercial orbital-transfer vehicles, including their demonstrated/upcoming capabilities.

Moving large payloads between substantially different orbits

• Impulse Space — particularly interesting because Helios is explicitly aimed at rapid LEO→GEO transportation.
• Blue Origin / Blue Ring
• Epic Aerospace
• D-Orbit

Actually touching and servicing satellites

• Northrop Grumman SpaceLogistics — the most operationally mature example; MEV has already performed commercial GEO satellite life extension, and MRV is expanding the capability to robotic servicing.
• Astroscale
• Starfish Space

Refueling specifically

• Orbit Fab
• Astroscale
• Impulse Space is also relevant as a transportation/hosting partner; it has worked with Orbit Fab on GEO refueling demonstrations.

The interesting distinction

If you're thinking about an eventual "UPS/FedEx for space", the most strategically interesting companies are probably D-Orbit, Impulse Space, Blue Ring, and Momentus on the transportation side, and SpaceLogistics, Astroscale, Starfish, and Orbit Fab on the servicing side.

The industry is moving toward a model where a satellite doesn't necessarily have to be launched into its final orbit, remain untouched for 15 years, and then be discarded. Instead, a tug can deliver it, reposition it, refuel it, inspect it, extend its life, and eventually move or deorbit it. RAND and NASA both describe this broader ecosystem as space logistics/in-space servicing.

If you're evaluating these companies as potential investments, customers, acquisition targets, or competitors, I can also rank them by flight heritage, funding/valuation, current revenue, target orbits, payload capacity, and how close each is to actual commercial servicing revenue.

The space logistics and in-space mobility market is broadly split into two main operational niches: orbital transfer vehicles (OTVs) or "space tugs" that move payloads between different orbits, and on-orbit servicing (OOS) companies that refuel, repair, or clean up active and defunct satellites.

Orbital Transfer Vehicles & "Last-Mile" Delivery (Moving Payloads)

These companies use specialized free-flying space tugs that ride up on standard rideshare rocket launches and then transport smallsats or payloads to unique, custom, or higher-energy orbits.

On-Orbit Servicing, Refueling & Life Extension (Servicing Satellites)

These companies focus on docking with, inspecting, refueling, repairing, or extending the operational lifespan of satellites already on station.

If you're looking into a specific mission profile, tell me:

• Are you trying to deploy a small satellite/constellation or service an existing asset?
• What is your target orbit (e.g., LEO, SSO, GEO)?

I can help narrow down which of these providers aligns best with your technical requirements.

Yes. The market is splitting into orbital transportation—moving spacecraft/payloads from one orbit to another—and on-orbit servicing—rendezvous, docking, refueling, inspection, repair, relocation, or deorbiting.

Leading companies

NASA's current commercial-vehicle overview specifically identifies D-Orbit, Impulse, Exotrail, Epic, Rocket Lab and others as commercial orbital-transfer providers.

The most interesting distinction

If you're asking "who can actually go get my satellite and move/service it?", I'd divide the field this way:

• Best demonstrated satellite servicing: Northrop Grumman SpaceLogistics. Its MEVs have already docked with operational GEO satellites and extended their lives; its new MRV adds robotic inspection, repair, upgrades and relocation.
• Broadest servicing ambition across orbits: Astroscale. It is developing inspection, servicing, refueling and removal capabilities based on rendezvous/proximity operations and docking.
• Best fit for "space tug" / orbital delivery: D-Orbit, Impulse Space, Exotrail and Momentus. Their vehicles are primarily designed to take payloads after launch and deliver them to different orbital destinations rather than physically repair another satellite.
• Most interesting autonomous-servicing startup: Starfish Space, whose Otter vehicle is designed around autonomous rendezvous and docking.
• Refueling infrastructure: Orbit Fab, with Astroscale also pursuing actual on-orbit refueling missions.
• Debris removal / capture: Astroscale and ClearSpace are particularly relevant.

So, conceptually, the industry is moving toward "FedEx + AAA + gas station for satellites": an OTV moves a spacecraft to the right orbit, a servicer can rendezvous with it, and eventually orbital depots can refuel it. The companies above are attacking different pieces of that stack.

If you're evaluating them as potential suppliers/investments/competitors, I can also rank these companies by (1) flight heritage, (2) actual orbital capability, (3) payload capacity/delta-v, (4) satellite servicing maturity, and (5) commercial/government contracts.

If you're asking "who can actually go get my satellite and move/service it?", I'd divide the field this way:

The space logistics sector is transforming spaceflight by treating launch vehicles as just the first leg of a journey . Companies specializing in orbital transfer vehicles (OTVs), space tugs , and on-orbit servicing (OOS) handle last-mile payload delivery, orbit adjustments, satellite life extension, and debris removal.

The key companies operating in this market are categorized below by their core logistics focus:

1. Orbital Transfer & Last-Mile Delivery (Space Tugs / OTVs)

These companies use modular spacecraft to take payloads from a primary rocket drop-off and maneuver them into custom orbits, altitudes, or inclinations.

• • D-Orbit : A prominent market leader providing last-mile satellite deployment, orbital transportation, and constellation phasing using their proprietary ION Satellite Carrier platform.
• • Impulse Space : Founded by former SpaceX propulsion engineers, they develop high-velocity OTVs (like Saigo and Mirza ) designed for fast orbit transfers, including heavy-payload movement from Low Earth Orbit (LEO) to higher altitudes.
• • Blue Origin : Developing Blue Ring , a massive multi-orbit logistics platform capable of heavy payload transport, hosting, and data relay from LEO all the way out to cislunar space and GEO.
• • Exotrail : A European space logistics provider offering end-to-end orbital mobility services via their Spacevan OTV line, combined with proprietary mission-optimization software.
• • Rocket Lab : Utilizes their versatile Photon spacecraft platform not just as an interplanetary probe bus, but as an orbital transfer and upper-stage vehicle capable of custom payload hosting and maneuvering.

2. Satellite Servicing & Life Extension

These firms focus on docking with, refueling, repairing, or boosting aging satellites that are already operational in orbit.

• • SpaceLogistics (Northrop Grumman): Pioneer of commercial GEO satellite life extension. They operate Mission Extension Vehicles (MEVs) that physically dock with aging client satellites to provide propulsion, and they are deploying Mission Robotic Vehicles (MRVs) equipped with robotic arms to install new Mission Extension Pods (MEPs).
• • Astroscale : A global leader in orbital sustainability and active debris removal, specializing in rendezvous, proximity operations, and life-extension/end-of-life architectures for defunct or uncooperative spacecraft.

3. Emerging Proximity Operations & Debris Mitigation

• • Starfish Space : Developing Otter , a small satellite servicing tug designed for life extension, station-keeping, and eventual decommissioning/disposal of LEO and GEO spacecraft backed by US Space Force and Space Development Agency (SDA) contracts.

If you're researching a specific mission, let me know:

• Are you looking for logistics in LEO (Low Earth Orbit) or GEO (Geostationary Earth Orbit)?
• Do you need payload delivery or active satellite intervention (refueling/docking)?

I can provide more targeted details or technical capabilities for those specific platforms.

Yes. The commercial space-logistics / in-space servicing market is now broad enough to split into two groups: companies that primarily move payloads between orbits, and companies that rendezvous with, move, refuel, repair, or deorbit existing satellites. Several do both.

Leading companies

NASA's current commercial orbital-transfer survey specifically identifies D-Orbit, Impulse, Exotrail, Atomos, Epic, Blue Origin and others as commercial orbital-transfer/maneuvering providers.

The most interesting ones

D-Orbit is probably the closest thing to an established space trucking company. Its ION vehicle has already flown operational missions, carrying and deploying customer spacecraft and performing orbital maneuvers.

Impulse Space is particularly interesting if you're thinking about LEO-to-GEO transportation. Its Mira vehicle provides orbital transport, payload hosting and deployment, while its much larger Helios vehicle is designed for high-energy transportation. NASA describes Helios as targeting transport of more than 4,000 kg from LEO to GEO in under 24 hours, with its first flight planned for 2026.

Northrop Grumman SpaceLogistics is the standout for actually grabbing and servicing an existing satellite rather than merely carrying a new payload. Its MEV spacecraft have docked with operational GEO satellites and extended their lives. Its next-generation Mission Robotic Vehicle is designed for inspection, relocation, repair, upgrades, disposal and installation of propulsion pods. It launched in July 2026.

Astroscale is arguably the broadest independent satellite-servicing specialist. Its technology centers on rendezvous, proximity operations and docking (RPOD), with applications including inspection, life extension, maneuvering, refueling and debris removal. Its U.S. operation is also developing Provisioner for on-orbit refueling.

Starfish Space is pursuing autonomous "tugs" that dock with satellites and then maneuver them. In 2026 it received a $54.5M Space Force contract for an Otter servicing vehicle intended for GEO, while another $52.5M contract covers deorbiting LEO constellation satellites.

A useful way to think about the market

There are essentially four layers emerging:

1. Orbital delivery trucks — D-Orbit, Exotrail, Impulse, Epic Move a spacecraft from its launch-insertion orbit to its operational orbit.
2. Heavy orbital transfer — Impulse/Helios, Blue Origin/Blue Ring Move substantial payloads across large orbital-energy differences, potentially including GEO and cislunar space.
3. Satellite tugs / servicing vehicles — Astroscale, Starfish, SpaceLogistics Rendezvous with an existing satellite and change its orbit, extend its life, inspect it, or eventually repair/refuel it.
4. Space fuel infrastructure — Orbit Fab and related efforts Supply propellant so satellites and servicing vehicles don't have to carry all their lifetime maneuvering fuel from launch.

The really interesting convergence is that #1 and #3 are starting to merge: instead of launching a satellite with enough propulsion to perform every maneuver it will ever need, you can envision launching a relatively fuel-efficient spacecraft and hiring an orbital logistics provider to deliver it, reposition it, refuel it, and eventually deorbit it.

If you're looking at this from an investment, competitive-landscape, or business-development perspective, I can also rank these companies by (a) actual flight heritage, (b) ability to move a customer's satellite between specific orbits, (c) servicing/refueling capability, and (d) likely market size.

The commercial space logistics market features specialized companies focusing on orbital transfer vehicles (OTVs) —often called "space tugs"—to move payloads between orbits, as well as firms developing in-orbit servicing (IOS) and active debris removal/satellite life-extension.

Orbital Transfer & Payload Delivery (Space Tugs)

• Impulse Space : Founded by former SpaceX propulsion lead Tom Mueller, they develop high-thrust OTVs like Mira (for precise orbit hosting and deployment) and Helios (for high-energy transfers from LEO to MEO, GEO, and beyond).
• D-Orbit : Known for its ION Satellite Carrier series, this pioneer in last-mile space logistics provides precision orbital deployment, satellite transportation, and in-orbit edge computing.
• Rocket Lab : Beyond its launch vehicles, the company utilizes its modular Photon spacecraft platform as an interplanetary and orbital transfer vehicle to deliver smallsats to custom orbits.
• TransAstra Corporation : Actively developing the Worker Bee orbital transfer vehicle designed for in-space mobility, cargo transport, and resource harvesting logistics.

• Orbit Fab : Focused on building an in-space propellant supply chain . They have pioneered operational commercial fuel depots in LEO and introduced the RAFTI (Rapidly Attachable Fluid Transfer Interface) refueling port as an emerging industry standard.
• Starfish Space : Developing the Otter spacecraft, focused on life extension, orbital maneuvering, and active end-of-life disposal/deorbit services for commercial and government clients.
• ClearSpace : A prominent European leader contracted for active debris removal (ADR) and future multi-use space tug/robotic arm orbital architecture.
• Northrop Grumman / SpaceLogistics : Operates the landmark Mission Extension Vehicle (MEV) fleet, which physically docks with geostationary satellites running low on fuel to take over station-keeping and extend their operating lives.

Are you looking for a logistics provider for a specific orbital transfer (e.g., LEO to GEO) , or are you researching satellite life-extension and refueling capabilities?

Companies in space logistics generally fall into a few categories:

1. Orbital transfer vehicles (OTVs) / space tugs — move payloads, satellites, or spacecraft from one orbit to another.
2. On-orbit servicing (OOS/ISAM) — inspect, repair, refuel, upgrade, relocate, or deorbit satellites.
3. In-space refueling and propellant logistics — provide fuel that enables maneuvering and life extension.

Here are some of the major players:

More mature / operational capabilities

• Northrop Grumman SpaceLogistics: one of the earliest commercial satellite servicing providers, with the Mission Extension Vehicle missions demonstrating GEO satellite life extension.
• D-Orbit: among the most active commercial orbital transport providers, having flown many ION missions for satellite deployment and orbital logistics.
• Astroscale: focused heavily on rendezvous, docking, debris removal, and satellite life extension across multiple orbital regimes.

Companies aimed at the future “space logistics network”

These are building toward a world where satellites can be treated more like aircraft:

• Fueling: Orbit Fab
• Towing/mobility: D-Orbit, Atomos Space, Momentus, Starfish Space
• Maintenance/repair: Astroscale, ClearSpace, Katalyst, Kurs Orbital
• Large GEO servicing: Northrop Grumman, Astroscale

The biggest commercial opportunities are expected to be:

• moving satellites from LEO to higher operational orbits
• relocating GEO satellites to new slots
• refueling satellites before they run out of propellant
• repairing or upgrading expensive spacecraft
• removing failed satellites and debris

The sector is often grouped under ISAM (In-Space Servicing, Assembly, and Manufacturing) and orbital mobility/logistics.

The space logistics market is divided into companies that focus on orbital transfer/last-mile cargo delivery (moving payloads between orbits using space tugs) and those that specialize in on-orbit satellite servicing (docking, life-extension, refueling, and debris removal).

Orbital Transfer & Payload Moving (Space Tugs / OTVs)

These companies use Orbital Transfer Vehicles (OTVs) to pick up payloads post-launch or deploy small satellites into custom, hard-to-reach orbits.

• D-Orbit Operates the ION Satellite Carrier, a flight-proven OTV that handles precision deployment, hosted payloads, and orbital repositioning.
• Impulse Space Develops high-velocity orbital maneuvering vehicles (like Helios) designed for heavy-impulse maneuvers and transfers from Low Earth Orbit (LEO) to higher-energy orbits like Geostationary Earth Orbit (GEO).
• Exotrail Builds the Spacevan orbital transfer vehicle line, utilizing electric propulsion for small satellite constellation deployment across LEO and higher orbits.
• Blue Origin Developing Blue Ring , a multi-orbit, high-capacity space logistics platform and tug designed for end-to-end transport from LEO to cislunar space alongside persistent hosting.
• Momentus Space Offers in-space transportation and orbital delivery via its Vigoride OTV architecture, moving small satellites from initial deployment orbits to custom destination slots.
• TransAstra Building the Worker Bee OTV line to provide logistics, payload delivery, and space domain awareness across LEO, Medium Earth Orbit (MEO), GEO, and cislunar space.

Satellite Servicing, Life Extension, & Active Debris Removal

These providers focus on physical rendezvous, proximity operations, and docking with existing, operational, or defunct spacecraft.

• SpaceLogistics (Northrop Grumman) A pioneer in commercial GEO servicing, famous for its Mission Extension Vehicles (MEVs) that dock with aging satellites to provide propulsion and life extension. Their next-gen Mission Robotic Vehicle (MRV) performs multi-mission robotic repairs, inspections, and installations.
• Astroscale Focuses on active debris removal, in-orbit inspection, and end-of-life deorbiting services, with demonstrated orbital capabilities targeting space sustainability.
• Katalyst Space Technologies Specializes in robotic satellite servicing and has deployed flight systems (such as the LINK vehicle) aimed at docking with and boosting the orbits of aging or decaying public/private observatories.
• Starfish Space Develops autonomous small spacecraft (the Otter architecture) designed for low-cost satellite servicing, life extension, and end-of-life disposal.
• Orbit Fab Specializes explicitly in the fuel logistics side of servicing, setting up an in-orbit refueling infrastructure ("gas stations in space") to supply operational spacecraft with propellant.

Are you looking into logistics for a specific orbital regime (like LEO vs. GEO), or are you interested in a particular service like satellite refueling vs. constellation deployment?

Yes. The market is splitting into orbital transportation (“space tugs”) and on-orbit servicing—and a few companies are pursuing both.

Leading companies

A few distinctions are particularly important.

Impulse Space is probably the closest match if you mean “a truck that takes my payload from one orbit to another.” Its Mira vehicle is already flying, while Helios is designed as a much more powerful transfer stage. Impulse explicitly describes its vehicles as moving payloads “across and between orbits”; Helios is intended to take substantial payload mass from LEO to GEO in under a day.

D-Orbit is the other major dedicated space-logistics company. Its ION Satellite Carrier provides last-mile delivery and orbital transportation, with dozens of missions and more than 100 satellites deployed according to the company's current figures.

Northrop Grumman/SpaceLogistics is the standout for actually servicing existing satellites. Its MEV spacecraft have docked with operational GEO communications satellites and provided propulsion/attitude control to extend their lives. Its next-generation Mission Robotic Vehicle adds robotic inspection, repair, upgrades, relocation, disposal and other servicing capabilities. The MRV/MEP mission launched in July 2026.

Astroscale and Starfish are especially interesting for robotic servicing. Astroscale has demonstrated rendezvous/proximity operations and docking and is pursuing inspection, life extension and debris removal. www.astroscale.com Starfish's Otter is intended to capture and service satellites, including spacecraft that weren't originally designed for docking; the company has already demonstrated autonomous proximity operations with Impulse's Mira vehicles.

Momentus sits between transportation and servicing. Its Vigoride vehicles have flown customer payloads and provide orbital delivery/hosting, while its 2026 Vigoride-7 mission is demonstrating autonomous rendezvous, assembly and satellite-servicing capabilities.

Exotrail is another genuine orbital-mobility player. Its SpaceVan provides last-mile delivery and orbital transfers using electric propulsion, with a GEO version intended to transfer payloads from GTO to GEO.

Orbit Fab is somewhat different: it isn't primarily a tug operator. Its focus is the fuel infrastructure that would make a logistics network possible. Its new RAVEN shuttle is designed to carry propellant to satellites equipped with its RAFTI interface, while NEST is the proposed depot infrastructure.

If you're looking for a commercial provider

I'd divide the field this way:

• “Take my payload from LEO to a different orbit” → Impulse Space, D-Orbit, Momentus, Exotrail
• “Go rendezvous with my satellite” → SpaceLogistics/Northrop, Astroscale, Starfish
• “Extend my satellite's life” → SpaceLogistics/Northrop, Astroscale, Starfish
• “Refuel my satellite” → Orbit Fab, SpaceLogistics, Astroscale
• “Remove/deorbit my dead satellite” → Astroscale, Starfish, ClearSpace
• “Build the infrastructure for an orbital logistics network” → Orbit Fab, D-Orbit, Impulse, Exotrail

The interesting part is that these are converging into the same business: launch a reusable-ish spacecraft, pick up or rendezvous with a payload, move it, refuel/service it, and eventually bring it to disposal. The U.S. Space Force is explicitly investigating orbital warehouses and transfer vehicles as a logistics architecture, with 2027 demonstrations involving Starfish and Astroscale.

If you're evaluating this as an investment/industry landscape, I can also rank these companies by (1) flight heritage, (2) actual revenue/commercial customers, (3) orbital-transfer capability, (4) servicing capability, and (5) likelihood of becoming the “FedEx/UPS of space.”

The space logistics market is generally split into orbital transfer/transportation (moving payloads or deploying smallsats to distinct orbits post-launch) and on-orbit servicing/life extension (docking with, repairing, or refueling existing satellites).

The primary commercial companies operating in these spaces include:

• Rocket Lab : Utilizes their customizable Photon spacecraft platform to act as an interplanetary and orbital kick stage/transfer vehicle for dedicated and rideshare payloads.

Are you looking into logistics for a specific orbital regime (like LEO constellation deployment vs. GEO servicing), or do you need details on a particular payload mass class?
