Same-day delivery comes to space, as Impulse promises satellite transport in hours, not months
Amazon turned same-day delivery into a global standard for shoppers. Now, same-day delivery comes to space, as Impulse promises satellite transport in hours, not months, redefining what’s possible beyond Earth. The California-based startup is positioning itself as the go-to courier for satellites heading to geostationary orbit (GEO), about 22,000 miles above the planet.
Traditionally, moving satellites to GEO takes months. Impulse wants to cut that journey down to just hours, reshaping how both commercial and defense operators deploy critical space infrastructure.
Impulse’s Bold Plan for Space Logistics
Impulse announced three major deals in just one week to prove its concept. These include:
-
A demonstration mission with defense contractor Anduril in 2026.
-
A satellite transportation deal with GEO communications startup Astranis in 2027.
-
A multi-launch agreement with Infinite Orbits to carry servicing satellites to GEO starting in 2027.
Each mission will showcase Impulse’s ability to accelerate space logistics and transform access to high-value orbital real estate.
The SpaceX Connection
Impulse was founded in 2021 by Tom Mueller, a propulsion veteran who spent nearly two decades at SpaceX. Mueller led the development of the famous Merlin and Raptor engines before leaving in 2020 to start his own venture.
His vision for Impulse is straightforward yet ambitious: create reliable “last-mile delivery” in low Earth orbit (LEO) while enabling same-day transport to GEO. This approach could become the new standard for satellite operators racing to stay ahead in a competitive industry.
How Impulse’s Helios Works
The centerpiece of Impulse’s strategy is Helios, a methane-oxygen kick stage. A kick stage functions like a booster that separates from a larger rocket and fires its own engine to push payloads into their final orbit.
Helios is powered by the Deneb engine, designed for efficiency and power. Acting as a courier, Helios could quickly move spacecraft from LEO (100 to 1,200 miles above Earth) to higher orbits like GEO — all in a fraction of the usual time.
This capability has caught the eye of both private companies and the U.S. Department of Defense, which sees value in rapid maneuvering during tense situations in orbit.
Why GEO Matters More Than Ever
Geostationary orbit is prime real estate in space. Satellites there maintain a fixed position relative to Earth, making them vital for communications, defense, and weather monitoring.
But reaching GEO isn’t easy. Spacecraft must pass through the hazardous Van Allen radiation belts, maintain precise positioning, and overcome latency challenges in long-distance communication. Impulse’s promise of same-day delivery to GEO could significantly reduce risks and costs, giving satellite operators a critical advantage.
The Future of Same-Day Space Transport
If Impulse delivers on its promises, the company could redefine space logistics much like Amazon did for e-commerce. Faster deployments mean companies can scale satellite networks rapidly, governments can react quicker to global events, and new industries may emerge around fast-turnaround orbital missions.
For now, the space industry is watching closely. With partnerships already secured and powerful tech under development, Impulse could be on the brink of changing how humanity operates in orbit.
