How Impulse Space’s Helios will democratize access to Earth’s farthest orbits

The cost of launching a payload into low-earth orbit has shrunk dramatically over the past two decades as SpaceX has aggressively expanded its capability to repeatedly launch payloads into orbit at cheap cost. But accessing orbits farther away from Earth, such as Medium Earth orbit (MEO) and Geostationary orbit (GEO), remain expensive endeavors. Lux’s portfolio company Impulse Space, which is building the next generation of rocket propulsion for space, unveiled the design specs of its new high performance kick stage vehicle Helios today. The vehicle will allow operators to move objects like satellites from Low Earth orbit to orbits farther away at just a fraction of today’s costs, and it’s coming soon in 2026. I talked with Impulse Space’s CEO and founder Tom Mueller about Helios, as well as the growing concerns over space junk, a recent satellite emergency over Christmas, the television show The Expanse, space traffic control and what it means to move things in space and bring them back home.
