Diagram

Vyom 2U: a complete propulsion module

Vyom combines a packaged thruster and electronics with a peroxide-based propellant; the company describes catalytic reaction followed by hot-gas expansion to generate thrust.

Use Enlarge drawing for detail. The tour caption explains the selected elements.

Step 1 of 4: See the actual module. Static diagram.

Guided reading, not physical motion.

Explore the diagram

Hover or focus an element to preview its evidence. Click or tap to pin it. Select another element or clear the selection to continue.

Choose an element to inspect its evidence.

Step timings allow time to read. They do not represent physical speed or duration.

See the actual module
Current photographs show electronics above a rectangular enclosure and a single thruster below. Electrical connectors are visible; internal plumbing and component suppliers are not established.
Release chemical energy
The company describes a peroxide-based blend reaching its catalyst and chamber. The functional sequence represents chemistry, not the internal arrangement of pipes or valves.
Turn hot gas into thrust
Gas expands through a nozzle and leaves as exhaust. Thrust acts oppositely. This principle does not depend on a drawn flame or atmospheric oxygen.
Read the flight evidence carefully
The company abstract reports pressure and temperature telemetry, platform motion and replica ground tests. It says orbital thrust could not be directly measured. Ratings across the current catalogue and conference abstract require reconciliation.

Left: current-product exterior schematic with electronics, enclosure and a thruster pointing down; exhaust points down and thrust up. Right: separate functional sequence from stored propellant to catalytic reaction and nozzle expansion. Captions disclose reconstructed flight performance and unresolved ratings.

Sources. [3] [17] [11] [18] [19]

Limitations.

Original explanatory drawing, not a manufacturing model or flight simulation. Company photographs support external appearance only. No internal plumbing, recipe, performance value or flow timing is inferred. The 2026 company abstract is accessible but its full paper and slides could not be downloaded. The external NASA GPIM paper concerns another propellant and is not used as Manastu's architecture.

Evidence

company claim. Current company photographs show an integrated module with electronics above its enclosure and one protruding thruster. [3] [18] [19]
company claim. The company describes a peroxide-based propellant blend supplied to a catalyst and reaction chamber. [3]
company claim. The company describes catalytic peroxide decomposition and fuel ignition. [3]
verified. A nozzle accelerates exhaust and thrust acts in the opposite direction. [17]
company claim. The company-authored conference abstract says orbital performance was reconstructed from telemetry and ground tests; thrust was not directly measured in orbit. [11]
analysis. Current product and conference descriptions contain unresolved configuration-dependent ratings. [3] [11]

Diagram elements

context: company claim. Sets the current product context and separates exterior appearance from functional sequence. Product gallery and About section [3] Limitation. Original schematic. Exterior proportions are illustrative; the right-hand sequence is not a cutaway or plumbing diagram.
electronics: company claim. Board, supports and connector sit above the enclosure. Native electronics close-up, viewed 1 November 2026 [19] Limitation. No pinout, processor identity, control algorithm or supplier inferred.
housing: company claim. Rectangular enclosure with a top-mounted board; hidden routing deliberately not depicted. Native Vyom module photograph, viewed 1 November 2026 [18] Limitation. Does not establish internal tank shape, feed valves, pressurant type or tank level.
thruster-body: company claim. One protruding thruster is mounted below the enclosure. Lower portion of current module photograph [18] Limitation. Simplified exterior silhouette and visible side feature, not internal nozzle geometry or measured dimensions.
propellant: company claim. Functional input stage, with a directional connection to reaction. Novel Propellant MS-289 section [3] Limitation. No formulation proportions, hazard-free claim, storage volume or specific feed design.
reaction: company claim. Company-described reaction creates hot gas. Cutting-Edge Catalyst and Advanced Engine sections [3] Limitation. Catalyst composition, temperature, geometry and exhaust species are not specified in the drawing.
exhaust: verified. Functional nozzle, exhaust arrows and opposite thrust arrow explain momentum direction. Rocket nozzle illustration and thrust explanation [17] Limitation. No thrust magnitude, plume shape or flow speed encoded. NASA reference does not validate company performance.
measurement: company claim. Visible note distinguishes reconstruction from directly measured orbital thrust. Abstract, final paragraphs on inertial uncertainty and performance reconstruction [11] Limitation. Company-authored abstract only. Full paper and presentation returned HTTP403.
rating-limit: analysis. Visible caveat prevents treating all ratings as one configuration. About narrative versus Technical Specifications table; compared with SmallSat abstract [3] Limitation. Continuous-burn and total-impulse differences remain unresolved.

Interactive 3D explainer

From a command to spacecraft thrust

Inspect the photographed Vyom exterior, then follow a separate functional explanation of liquid supply, reaction and directed exhaust.

The static explanation below is available without 3D or JavaScript.

Evidence boundary. The exterior follows company photographs. Functional views are not an internal cutaway: tank, feed layout and catalyst packing remain unknown. Timing and flow marks are explanatory.

Static explanation and all component roles

Product exterior: a stationary explanatory view, not measured motion.
Power and commands: a stationary explanatory view, not measured motion.
Stepped outlet: a stationary explanatory view, not measured motion.
How thrust works: a stationary explanatory view, not measured motion.

Module enclosure

The closed enclosure holds the assembly and provides mechanical interfaces to its host.

Purpose. The spacecraft needs a propulsion module it can mount and connect.

Illustrative external proportions. Unseen construction and alloy are not established.

company claim | inspected 2026-11-01 | Source 1 | Source 2

Power and command interface

A raised board, connector and harness are visible above the enclosure. The module receives power and operating commands.

Purpose. Propulsion must respond to the spacecraft rather than fire continuously.

Package silhouettes follow the photograph. No chip identity, circuit traces or pinout is asserted.

company claim | inspected 2026-11-01 | Source 1 | Source 2 | Source 3

Stored propellant

Stored MS289 liquid supplies chemical energy to the reaction stage.

Purpose. The requested manoeuvre requires an available propellant supply.

The labelled input is a functional symbol, not an observed flight tank or liquid level.

company claim | inspected 2026-11-01 | Source 1 | Source 2

Catalyst and reaction

A catalyst-assisted reaction converts incoming propellant into hot gas.

Purpose. Chemical energy must become gas energy before the nozzle can produce thrust.

Granules refer to a catalyst photograph, not a measured bed, material composition or temperature field.

company claim | inspected 2026-11-01 | Source 1 | Source 2

Thruster outlet

The photographed module has a stepped narrow outlet. The separate functional section explains gas acceleration through a nozzle.

Purpose. Directed gas flow establishes a useful thrust direction.

The functional section is not Vyom internal geometry. The standalone engine bell is not grafted onto this product.

company claim | inspected 2026-11-01 | Source 1 | Source 2

Exhaust and thrust

Exhaust carries momentum one way; thrust acts on the spacecraft in the opposite direction.

Purpose. This is how propulsion changes spacecraft motion.

Arrows show direction only. No force, velocity, plume temperature or trajectory is simulated.

Space-sector signal

USD 2.36bn

Rocket Lab reported contracted backlog at Q2 2026 and quarterly revenue of about USD 234m. [F2]

A diversified launch and space-systems comparator; its backlog is not propulsion-only demand or Manastu orders.

What the market signal means

Capital support meets qualification risk

Government support reduces one financing hurdle. The commercial case still depends on accepted propulsion systems, repeat orders and the cost of qualification, propellant handling and support. [F1] [F2]

Programme funding, peer backlog and startup revenue are different measures.

Questions that change the financial case

What are the drawdown milestones, conversion terms and remaining project-financing obligations?

India's Technology Development Board announced a signed agreement on 26 October for INR116 crore of optionally convertible debt. The stated project cost is INR277.63 crore. An agreement is not evidence that cash has been disbursed. [1]
verified
The government announcement names Manastu Space Technologies Private Limited in Navi Mumbai. The current shareholder register and ultimate control were not obtained. [1]
verified
The programme covers a proposed 5 mN to 300 N propulsion range and targets progression from TRL6 to TRL9. These are programme aims, not proof that every product has reached the same readiness. [1]
company claim
ISRO's December 2024 mission description identifies Manastu's hydrogen-peroxide thruster as a POEM-4 payload. That pre-flight description does not verify later measured performance. [2]
verified
The current Vyom 2U page reports a 360-second continuous orbital burn but lists 30 seconds as maximum continuous firing in its specification table. The configuration or rating distinction remains unresolved. [3]
analysis
August reporting had already identified the INR116 crore selection. October's distinct event is the signed agreement, not the first announcement of the allocation. [5] [1]
analysis
Inc42 separately reported INR22 crore of financing from regulatory filings. This should not be merged with the government agreement as one completed cash round. [7] [1]

Assessment

Topic	Reading and evidence
Team and execution	The company names Tushar Jadhav and Ashtesh Kumar as its founders. Production-quality leadership, repeat manufacturing experience and responsibility for scale-up remain unverified. Obtain the operating team structure and relevant delivery records. [4] analysis
Product and mechanism	Hydrogen-peroxide-based propulsion combines propellant, catalyst, feed system and thruster. Verify each configuration separately; a small thruster result does not validate the entire planned range. [3] [1] analysis
Customers and buying process	Satellite builders need mission-specific thrust, lifetime, restart behaviour and integration evidence. Qualification and acceptance could dominate price in procurement. [2] [3] analysis
Commercial proof	The company's history names earlier contracts and deliveries. No contract schedule, customer acceptance record or repeat-order revenue was obtained. [4] analysis
Pricing or economics	Not established. Obtain delivered price, qualification cost, manufacturing yield, propellant logistics and lifetime support cost for comparable missions. unknown
Competitors and substitutes	ISRO's payload list includes another green-propulsion demonstrator from Bellatrix. Shared mission presence provides context, not a matched performance comparison. [2] analysis
Distribution	The company offers integration and related mission services. Separate engineering-service revenue from repeat product sales when evaluating scale. [4] analysis
Intellectual property or defensibility	Proprietary propellant and catalyst claims need patent, assignment and process evidence. Neither a trade name nor a funding decision proves defensibility. [3] analysis
Manufacturing or operational scaling	The programme requires engineering, system integration and validation. A production qualification plan should include lot consistency, catalyst life and acceptance yield. [1] analysis
Regulation	Not established. Obtain applicable export permissions, propellant handling requirements and launch-provider acceptance for the specific configuration. unknown
Capital needs	Debt conversion terms, repayment triggers and the remaining project finance are unknown. The headline amount alone cannot establish runway or dilution. [1] analysis
Key risks	Prior reporting questioned links between selection-panel members and funded companies. Members said they disclosed interests and recused themselves; the report is not a finding of wrongdoing by Manastu. [5] analysis
Next falsifiable milestone	Obtain disbursement and milestone terms, then independent acceptance results for a defined production configuration. A new product announcement alone would not establish readiness. [1] analysis
Funding context	September reporting described a pause in fresh programme applications and funding constraints. It does not establish non-payment under this later company agreement. [6] analysis
Public-market context	The comparisons below use Rocket Lab group financials and an optional hosted share-price chart. Its mix of launch and space systems limits comparison with Manastu propulsion. Neither the group figures nor its share price establishes a private Manastu valuation. [8] analysis

Opinion

The strongest question is whether an earlier demonstration can become a repeatable propulsion supplier across several sizes. Financing can support that transition, but qualification cost and payment terms determine whether scale is attractive. I would prioritise a defined production configuration with independent customer acceptance.

Limits. This view is provisional. Product ratings conflict, ownership is incomplete and financing terms are unavailable. Failed repeatability, slow qualification or burdensome conversion terms would weaken the case.

Competitive landscape · 2026-11-01

Who else solves this?

Small-satellite propulsion: chemical competitors and an electric alternative.

Comparison lens. Manastu must compete at complete-system level: propellant handling, thrust, power, mass, mission duration and demonstrated reliability. Electric propulsion can be attractive for some manoeuvres but is not a drop-in replacement for rapid chemical burns. analysis

Direct competitor · India; US presence

Bellatrix Rudra

Green chemical thrusters using a proprietary propellant and catalyst.

Difference: Closest regional procurement comparison; Manastu must show an advantage on matched thrust, lifetime and handling requirements.
Maturity: Bellatrix reports flight-qualified core technology and a 2026 move towards repeatable commercial manufacturing.
Economics: No matched unit-price quote; claimed manufacturing improvements do not establish a cost advantage.
Funding / ownership: Company announced a US$20 million pre-Series B round led by Cactus Partners on 28 March 2026.

The round covers the business, not Rudra alone; company flight and production statements require mission-specific verification.

Established supplier · Sweden

ECAPS

High-performance green chemical propulsion using LMP-103S.

Difference: An established alternative chemistry; compare storage, qualification and integration rather than the green label alone.
Maturity: NASA documents PRISMA demonstration and subsequent satellite applications of ECAPS propulsion.
Economics: System pricing and ground-handling cost on an equivalent mission are not disclosed.
Funding / ownership: Current ownership and dedicated programme funding were not established in the inspected sources.

Historical flight applications do not guarantee delivery or qualification for a new configuration.

Direct competitor · United States

Busek BGT-X5

Compact green monopropellant system using ASCENT propellant.

Difference: A small-spacecraft chemical alternative; tankage, thrust and integration envelope must match the intended Manastu configuration.
Maturity: Marketed product with technical specifications; cited microvalve heritage is not proof that the whole package has flown.
Economics: Public system price and complete mission integration cost are not stated.
Funding / ownership: Busek product programme; dedicated funding and current capital structure are not disclosed on the product page.

Component heritage and product specifications should not be converted into system-level reliability claims.

Direct competitor · New Zealand and the Netherlands

Dawn Aerospace

Integrated chemical propulsion using nitrous oxide and a hydrocarbon fuel, including SatDrive and CubeDrive.

Difference: A bipropellant architecture with different integration and handling requirements from a monopropellant approach.
Maturity: Company maintains a dated mission-heritage list and markets integrated propulsion systems.
Economics: Public lead-time guidance is not a binding quote; matched lifecycle cost is unknown.
Funding / ownership: Programme funding and ownership detail are not provided in these product and mission sources.

Mission counts are company-reported and do not establish independent failure rates.

Alternative approach · Austria

ENPULSION

Field-emission electric propulsion for small spacecraft.

Difference: Electric thrust changes the trade between electrical power, propellant efficiency and manoeuvre duration; it cannot substitute for every chemical burn.
Maturity: Markets a family of electric propulsion products with configuration-specific specifications.
Economics: No matched system quotation or mission energy-cost comparison is available here.
Funding / ownership: Company product line; current funding allocation and cap table were not established.

Compare against the actual spacecraft power budget and required manoeuvre time, not headline efficiency alone.

analysis

Sources and dates

ENPULSION product family (published date not stated; accessed 2026-11-01)

Coverage limits. Five named alternatives cover different chemistries and mission envelopes. No matched delivered-system quotations, insurance terms, production yields or independent reliability ranking were found. Flight heritage of one component or variant does not qualify an entire family.
