Space based manufacturing company that is building machines to produce the space infrastructure of the future. In-Space Mobility will transform and accelerate the development of space economy.
Optimus-1, the largest commercial satellite under construction in Australia, is an orbital transfer vehicle providing cost-effective insertion of small satellites into low Earth orbit.
Our services
- Transporter - Extremely efficient and capable space platforms that can be used to transport cargo and help build infrastructure in space.
- OrbitSide Service - Entirely reusable transportation supporting refueling, lifetime extensions, de-orbiting, repairing, and in-space assembly.
- Exploration as a Service - Cost-effective and versatile transportation platform that supports deep space exploration and scientific research missions to the Moon, Mars and beyond.
Where we’re headed:
- Q2 2022 - Qualification Launch of our Orbital Transport, Optimus
- Q1 2023 - Limited Commercial Flight of Optimus to Low Earth Orbit (LEO)
- Q4 2023 - Commercial Flight to LEO and Qualification for Geostationary Orbit (GEO)
- 2024 ONWARDS - Regular Flights to LEO, GEO and Deep-Space Qualification
- Spaceium will showcase its cutting-edge cryogenic storage capabilities on the Space Machines Company’s platform.
- Following this demonstration, Spaceium will refuel Space Machines Company spacecraft’s tank with cryogenic fuel using the stored reserves to highlight Spaceium’s refueling capability.
Space Machines Company targets 2026 for its next launch, 2024-04-19.
- Send an operational fleet of Optimus satellites into orbit within the next two years, bringing it closer to its ambition of providing the galactic equivalent of NRMA’s roadside assistance service.
- “The second, third and fourth vehicles will start to deliver services like inspection, monitoring and the rest of it,” founder Rajat Kulshrestha said. “We expect that in the next 24 months, 18-24 months.”
- In early March, we successfully launched Optimus into orbit aboard a SpaceX rocket.
- However, despite relentless efforts, including round-the-clock mission operations at our Adelaide operations centre and support from Australian and international partners to track the spacecraft from multiple ground stations globally, we have been unable to establish communications with Optimus.
Optimus Viper
Space Machines Company unveils Optimus Viper, 2024-12-16.
- Spacecraft designed to provide high-fidelity intelligence and protection for space assets.
- Space Machines Company (SMC) has unveiled Optimus Viper, a rapid-response spacecraft variant specifically designed to provide immediate, high-fidelity intelligence and protection for critical space assets.
- Operating at distances less than 10 kilometres from target satellites, Optimus Viper delivers the kind of detailed, actionable intelligence about critical space infrastructure that, until now, has been impossible to achieve. This announcement signals a fundamental shift in space operations, introducing the world’s first distributed, hyperscale production approach to delivering rapid on-orbit response for both national security and commercial space assets.
- Building on lessons learned from the launch of SMC’s inaugural satellite Optimus earlier this year aboard a SpaceX Falcon 9 rocket, Optimus Viper represents a fundamental shift in space security architecture. This agile 200-kilogram class “space first responder” can deploy within 24 hours of launch and operate within 10 kilometres of target satellites, combining enhanced autonomous capabilities with Solstice OS (Space Machines AI-driven orbital operating system) to deliver a dynamic, adaptive space presence that becomes more capable as it scales. The platform’s multi-mission flexibility enables rapid reconfiguration for different objectives, from space domain awareness to precise orbital monitoring.
- In a world-first announcement that democratises access to space asset protection, SMC is introducing commercial pricing for proximity inspection at $2-3M USD per inspection in Low Earth Orbit (LEO)—a fraction of the tens of millions it can cost currently.

Status Comment / Notes
First satellite Optimus-1 was launched in March 2024 but no contact was established.
