Draft:Space Machines Company

From Wikipedia, the free encyclopedia
  • Comment: Well done on creating the draft, and it may potentially meet the relevant requirements (including WP:GNG, WP:NCORP) but presently it is not clear that it does.
    As you may know, Wikipedia's basic requirement for entry is that the subject is notable. Essentially subjects are presumed notable if they have received significant coverage in multiple published secondary sources that are reliable, intellectually independent of each other, and independent of the subject. To properly create such a draft page, please see the articles 'Your First Article', 'Referencing for Beginners' and 'Easier Referencing for Beginners'. In short, "notability" requires reliable sources about the subject, rather than by the subject.
    Please note that some of the references would appear to be from sources that are NOT considered reliable for establishing notability and should be removed (including blogs, company websites, press releases, Twitter, YouTube, Instagram, Spotify etc).
    Please remove any broken (red) links to non-existent Wikipedia pages.
    Thank you for declaring your conflict of interest. Please note that if you have not already done so, you must also declare your COI on your Talk page (to see instructions on how to do this please click the link). Given the conflict, the review of the page needs to be handled with care, mindful of the higher bar set by pages produced in circumstances of conflict of interest. Such pages typically may read too much like a promotional CV or advertorial (see WP:PROMO), which Wikipedia is not; and/or contain prose that is not of a standard appropriate for an encyclopaedia (also see WP:PEACOCK and WP:NPV).
    Please familiarise yourself with these pages before amending the draft. If you feel you can meet these requirements, then please make the necessary amendments before resubmitting the page.
    It would help our volunteer reviewers by identifying, on the draft's talk page, the WP:THREE best sources that establish notability of the subject.
    It would also be helpful if you could please identify with specificity, exactly which criteria you believe the page meets (eg "I think the page now meets WP:NCORP criteria #3, because XXXXX").
    Once you have implemented these suggestions, you may also wish to leave a note for me on my talk page, including the name of the draft page, and I would be happy to reassess. Cabrils (talk) 22:29, 12 December 2025 (UTC)

Space Machines Company (SMC) is an Australian space technology company that develops orbital servicing capabilities and space infrastructure solutions. Founded in 2019 and headquartered in Sydney, the company specialises in developing rapid response vehicles and command systems for satellite inspection, monitoring, and protection services.[1]

History

[edit]

Space Machines Company was founded in 2019 by Rajat Kulshrestha and George Freney.[2] The company is based at the University of Technology Sydney's Tech Lab in Botany, New South Wales, with additional offices in Adelaide, South Australia, and Bangalore, India.[1][3]

Optimus mission

[edit]

On 5 March 2024, SMC launched their first vehicle, Optimus Rollout, aboard SpaceX's Falcon 9 rocket during the Transporter-10 mission from Vandenberg Space Force Base.[4][5][6] The 270-kilogram Orbital Servicing Vehicle was Australia's largest private satellite.[7]

Despite successful launch and deployment into orbit, Space Machines Company was unable to establish communications with Optimus. In May 2024, after several weeks of attempts to make contact, the company confirmed it had been unable to establish communications with the spacecraft.[8][9][10]

Space MAITRI mission

[edit]

In April 2024, SMC was awarded an A$8.5 million grant from the Australian Space Agency's International Space Investment (ISI) India Projects programme for Space MAITRI (Mission for Australia-India's Technology, Research and Innovation), a joint Australian-Indian mission focused on space debris management.[11][12]

The mission brings together multiple Australian and Indian partners including Digantara, Ananth Technologies, the University of Adelaide, University of Sydney, University of Technology Sydney, LeoLabs, Australian Strategic Policy Institute, HEO, OrbitAID, Indian Space Research Organisation (ISRO) through NewSpace India Limited, Lúnasa, Indian Institute of Science, and Australian Astronomical Optics at Macquarie University.[11] The mission is scheduled to launch in late 2026 aboard India's Small Satellite Launch Vehicle (SSLV).[11]

Optimus Viper announcement

[edit]

In December 2024, the company unveiled Optimus Viper, a rapid-response spacecraft variant designed specifically for space domain awareness and asset protection missions.[13][14]

Manufacturing facility expansion

[edit]

In June 2025, SMC announced a partnership with the University of Technology Sydney to establish the Optimus Factory (OF-01), described as Australia's largest industrial-scale spacecraft manufacturing facility.[15][16] The facility, located at UTS Tech Lab in Sydney, is designed to produce up to 20 Optimus Viper spacecraft annually, with capacity for simultaneous production of five spacecraft.[17]

In September 2025, SMC signed an agreement with the Bradfield Development Authority to establish manufacturing operations at the Advanced Manufacturing Research Facility in Bradfield, a planned city in Western Sydney.[18] The partnership is intended to support increased production capacity as part of the company's manufacturing scale-up plans.[18]

Products and technology

[edit]

Optimus Viper Rapid Response Vehicle

[edit]

The Optimus Viper is SMC's primary spacecraft platform, a 200-kilogram small satellite designed for proximity operations and rapid orbital response. Key specifications include 500 m/s of delta-v capability, modular payload hosting with streamlined integration processes, and a target production cost of less than US$1.25 million per unit. The platform use chemical propulsion and is designed to operate across LEO, MEO, GEO, and beyond-GEO orbits.

The spacecraft features the company's internally developed Scintilla propulsion system, a regeneratively cooled bi-propellant thruster capable of more than 1,000 ignition cycles. The platform is designed for autonomous proximity operations within 10 kilometres of target satellites, providing sub-centimetre resolution imagery from 1-kilometre standoff distances.[13]

Solstice OS

[edit]

Solstice OS is SMC's command and control software platform for managing orbital assets. The system is designed to provide real-time mission planning and execution capabilities, space domain awareness integration, autonomous command and control for multiple vehicles, and sub-second state synchronisation across network elements. The platform is being developed in phases, with Solstice OS 1.1 focused on mission planning and simulation, version 1.2 adding operational integration with physical assets, and version 1.3 delivering full multi-vehicle coordination capabilities.

Business model

[edit]

SMC positions itself as providing "orbitside assist" services, offering rapid response capabilities for satellite inspection, monitoring, and protection.[1] The company has announced commercial pricing for proximity inspection services starting at US$2–3 million per inspection in low Earth orbit.[13]

The company's strategy focuses on achieving cost reductions through volume manufacturing, targeting production of more than 30 vehicles annually by the late 2020s at a target unit cost below US$1.25 million.

Partnerships

[edit]

SMC has established partnerships with various organisations for launch services, technology development, and research collaboration.

Launch and technology partnerships

[edit]

The company works with SpaceX and NewSpace India Limited for launch services, and has technology partnerships with Advanced Navigation, Orbit Fab, ANT61, CSIRO, LeoLabs, Digantara, and Ananth Technologies.[7][19][11]

Research and academic partnerships

[edit]

SMC collaborates with the University of Technology Sydney, University of Adelaide, University of Sydney, and Macquarie University for research and development activities.[7][11]

International partnerships

[edit]

Through the UK Space Agency's International Bilateral Fund, SMC participates in two collaborative projects under the UK-Australia Space Bridge. The SLOSH-CAT project with Satellite Applications Catapult and University of Sydney examines liquid fuel movement in spacecraft to improve stability and control systems.[20] The ARGUS project with Lúnasa develops autonomous rendezvous technology for geostationary orbit operations.[20]

The company has also established partnerships with Reaction Dynamics (Canada) and other international organisations.

Government agency collaboration

[edit]

SMC collaborates with government agencies including the Australian Space Agency, Indian Space Research Organisation, UK Space Agency, Canadian Space Agency, and Australian defence organisations.[11][20] The company has established partnerships with state governments, including Investment NSW for manufacturing development in Western Sydney.[18]

Funding

[edit]

SMC has raised approximately A$2.25 million in funding, with investors including RADventures.[21] The company has received grant support from the Australian Space Agency, including the A$8.5 million ISI India Projects grant.[11] In 2025, the company also secured federal funding through the Defence Trailblazer's Accelerating Sovereign Industrial Capabilities program for space domain awareness technology development.[22]
