WASHINGTON \u2014 Satellite manufacturer K2 Space announced plans to launch a three-spacecraft mission in 2027 on a dedicated SpaceX Falcon 9 rocket, with each satellite deploying to a different orbital regime to prove out the startup\u2019s bet on a multi-orbit satellite platform.<\/p>\n

The mission, dubbed Trinity, will see two spacecraft deployed in low and medium Earth orbits, with a third heading to geostationary transfer orbit.<\/p>\n

\u201cWe are building a true multi-orbit bus that can proliferate in LEO, in MEO, and out to GEO,\u201d said Karan Kunjur, co-founder and CEO of California-based K2 Space. \u201cWe decided to prove it by deploying into all three orbital regimes on one rocket launch.\u201d<\/p>\n

It\u2019s a different approach in an industry where satellite platforms are typically purpose-built for specific orbits, each with their own design trade-offs and customizations.<\/p>\n

Proving out components<\/p>\n

The Trinity mission is the next step in a series of in-orbit tests.\u00a0<\/p>\n

In a demonstration flight earlier this year using another company\u2019s spacecraft, K2 validated many of the satellite components it developed in-house, including its flight computer, reaction wheel and flight avionics. K2 has not yet flown its electric propulsion system, a high-power 20-kilowatt Hall-effect thruster that has been test-fired at the company\u2019s Torrance headquarters.\u00a0<\/p>\n

K2 in 2026 plans to launch its Gravitas mission, funded by the U.S. Space Force<\/a>. This will be the company\u2019s \u201cMega\u201d class satellite\u2019s first flight in MEO, where it will operate at several different altitudes while carrying 12 national security and commercial payloads. Among them is a \u201cpathfinder\u201d mission for SES<\/a>, the satellite communications firm operating a MEO broadband constellation.<\/p>\n

The mission will test the satellite\u2019s survivability in MEO\u2019s high radiation environments. Powered by two 20-kilowatt thrusters, the satellite will attempt to raise itself from LEO to MEO over several months. The Mega class is designed to accommodate payloads of about 1,000 kilograms.<\/p>\n

Part\u00a0 of the Gravitas mission entails stopping at different altitudes to characterize the space environment from a radiation perspective, Kunjur said.\u00a0<\/p>\n

In the 2027 mission, K2 will have two satellites dropped off in LEO. One will remain in that lower orbit for a period before raising itself to MEO, while the other will immediately begin climbing to MEO and will aim to complete the orbit raise within 90 days. The third satellite will fly directly to geostationary transfer orbit.<\/p>\n

That third destination is particularly challenging. GTO is a high radiation environment that\u2019s historically been really hard to operate in, Kunjur explained. \u201cWe\u2019re going to show our customers and the markets what\u2019s possible with the K2 platform in that orbit as well.\u201d<\/p>\n

Pitch to customers<\/p>\n

Founded in 2022, K2 Space has raised $180 million in venture funding<\/a> and has reported $50 million in government and commercial contracts.<\/p>\n

K2\u2019s pitch to customers centers on an economic argument: moving constellations from LEO to MEO could reduce costs, even if individual satellites are more expensive. The reasoning is that fewer satellites are needed for coverage at higher altitudes.<\/p>\n

\u201cIt\u2019s just basic math,\u201d said John Plumb, K2\u2019s head of strategy and former Pentagon space policy official. \u201cThere\u2019s fewer satellites required for global coverage as you go up in altitude. It\u2019s straightforward to come up with an altitude at which, if you needed 150 satellites in LEO, you would only need 50 satellites in MEO.\u201d<\/p>\n

K2 advertises a price point<\/a> of $15 million per bus and offers its platform either as a rideshare bus for multiple customer payloads or as a dedicated platform for a single customer.<\/p>\n

Currently, low-cost satellite platforms aren\u2019t built to survive and operate in the higher-radiation environments of MEO and beyond, according to K2. The company believes its radiation-hardened, multi-orbit design fills that gap.<\/p>\n

K2 isn\u2019t yet disclosing specific customers for the 2027 mission, but Kunjur said the primary customers are already lined up. One customer from the 2026 Gravitas mission purchased a full satellite for Trinity, while another government customer is also returning.<\/p>\n

\u201cWhat we\u2019re seeing is interest in taking this iterative approach from our customers to use subsequent missions to buy down risk on future capabilities and test certain architectures that they want to pursue,\u201d Kunjur said. The company still has leftover hosted payload space available in the Trinity mission for customers that are looking to fly hardware.<\/p>\n

Developing a satellite platform to operate in multiple orbits \u201cwas always a game of trade offs and redesigns and customization,\u201d Kunjur said. \u201cWhat we wanted to do was build a single satellite that can handle all three orbits, a single satellite that is designed for the harshest radiation environment.\u201d<\/p>\n

There is some customization, however. The GEO configuration is 95% common with the LEO and MEO versions, and has four thrusters, or twice the power of the standard Mega bus. \u201cThat 5% is what we consider customization required to make the jump from MEO to GEO,\u201d Kunjur added.<\/p>\n

Plumb, who while at the Pentagon worked on the department\u2019s commercial space strategy, argues that both government and commercial customers are demanding \u201cmore power, more capability and lower cost,\u201d and K2 is looking to deliver a \u201cfundamentally different model for how space missions are designed and launched.\u201d<\/p>\n

He suggested that national security missions currently planned for LEO \u2014 including communications and remote sensing \u2014 could be moved to MEO using K2\u2019s platform at lower overall cost.<\/p>\n

K2 is also pushing for the military to rethink some acquisition requirements. Plumb pointed to ESPA (Evolved Secondary Payload Adapter) rings as an example of requirements that constrain military satellite programs. These rings, a long-standing standard designed to enable secondary payloads to piggyback on launches, physically attach multiple smaller satellites radially around a ring adapter within the launch vehicle\u2019s fairing.<\/p>\n

ESPA-based requirements force military programs into smaller payloads with specific form factors and mass budgets, preventing the military from leveraging commercial products like K2\u2019s larger platforms, said Plumb.<\/p>\n

\u201cWe have to get out of legacy requirements if we\u2019re going to achieve new effects at lower cost,\u201d he said, while noting he\u2019s \u201cbeen impressed with the folks we\u2019re working with\u201d at the Space Force on acquisition reforms. \u201cI think the whole government would benefit by just going after the effects they need and leaving the solutions up to the companies.\u201d<\/p>\n

K2 is also eyeing the Golden Dome missile defense program, which the Pentagon envisions will include space-based sensors and interceptors. The Mega-class satellites that will be launched in 2026 and 2027 are \u201cthe exact full size satellite that could be used in future Golden Dome architectures,\u201d Kunjur said.<\/p>\n
