Katalyst Space announced $12M in funding yesterday to support the development of its first GEO-capable robotic servicing spacecraft—called NEXUS—which is scheduled to launch its debut mission on an Arianespace Ariane 6 rocket in 2027.

Geodesic Capital led the round, which included participation from Fortitude Ventures and other undisclosed sources.

Level up: Katalyst’s first GEO mission in 2027 will be preceded by a mission closer to home, launching this month.

As part of a $30M NASA contract, awarded in September, Katalyst will use its LINK robotic spacecraft to rendezvous and dock with NASA’s Neil Gehrels Swift Observatory. The mission will provide a boost for the orbital telescope, which would otherwise fall back to Earth later this year. LINK has been integrated onto Northrop Grumman’s Pegasus XL rocket, and is scheduled to launch on June 27 from Northrop Grumman’s Stargazer aircraft.

NEXUS will have the same robotic RPO capabilities as LINK, but with double the power, mass and Delta-V, according to Katalyst CEO Ghonhee Lee.

For the 2027 flight to GEO, Katalyst has three different missions planned with the same spacecraft to demonstrate its range of in-space servicing capabilities:

  • NEXUS will rendezvous with the Space Force’s Rooster satellite and install Katalyst’s SIGHT module, which offers SDA capabilities.
  • After leaving Rooster, NEXUS will then conduct additional SDA and RPO missions for the US government, using its SHIELD deployable inspection module.
  • For its final trick, NEXUS will dock with a commercial GEO satellite to provide life-extension services—Katalyst is in the final stages of signing a contract with the customer for this part of the mission, according to Lee.

Margin call: With NEXUS, Katalyst is hoping to prove that the possibilities for in-space servicing are much broader than relatively routine life-extension missions.

“I want us to move away from conversations around life extension as synonymous with satellite servicing,” Lee said. “If you’re going to do any of these things in space, whether it’s orbital data centers, or you’re going to build out lunar infrastructure…you need robotics that can manipulate the environment.”

After NEXUS-1, Katalyst plans to deploy a fleet of NEXUS spacecraft to orbit—with the aim of providing multiple revenue-generating services with each sat, resulting in larger margins for each spacecraft. 

“The economics on the [GEO] missions are better because you have the density of spacecraft all in one orbital plane,” Lee said. “So it’s very easy for us to load many customers onto a single mission…the margins on the business are quite spectacular.”
