Amazon made same-day supply the benchmark on Earth. Impulse Space is pitching the same idea for satellites sure for geostationary orbit about 22,000 miles above Earth, compressing what is often a months-long transit right into a matter of hours.
Within the span of every week, the in-space propulsion startup introduced a trio of offers aiming to unlock geostationary orbit (GEO) for business and protection customers. That features a demonstration mission with protection contractor Anduril deliberate for 2026; a transportation cope with GEO communications startup Astranis in 2027; and a multi-launch settlement to hold Infinite Orbits’ servicing satellites to GEO beginning the identical yr.
Tom Mueller based Impulse in 2021 after almost twenty years main propulsion at SpaceX, the place he led growth of the Merlin and Raptor engines. He left SpaceX in 2020 and began Impulse to construct out in-space transport companies centered on last-mile supply in low Earth orbit (LEO) — which is often 100 to 1,200 miles above Earth — and ultra-fast satellite tv for pc transport to GEO.
The widespread denominator throughout these missions is Helios, Impulse’s methane-oxygen kick stage. A kick stage is basically a small rocket engine system that rides on a bigger rocket after which fires its personal engine – on this case, a strong engine referred to as Deneb – to propel spacecraft to their remaining vacation spot.
Helios is supposed to be the “identical day” courier from LEO to larger altitude orbits. If it performs as marketed, business operators might attain larger orbits a lot quicker, and the Division of Protection might maneuver extra rapidly in an more and more contested area of house.
GEO isn’t simply distant. Getting there and working satellites from there presents particular challenges. Spacecraft should transit the high-radiation Van Allen belts — zones of charged particles trapped by Earth’s magnetic subject — cope with latency in long-distance communication, and keep their exact place.
The partnership between Anduril and Impulse might show particularly profitable. The pair will collectively construct a demo satellite tv for pc for rendezvous and proximity operations — a functionality that enables spacecraft to strategy and examine different objects in orbit — which the House Drive has recognized as vital for house area consciousness and deterrence.

Impulse is supplying the spacecraft – referred to as Mira, which flew for the primary time final yr – whereas Anduril will present a mission information processor, long-wave infrared imager, and different software-defined payloads geared toward monitoring and high-precision navigation.
As a part of the demo, Helios will ferry the spacecraft to GEO in below a day, after which the mission goals to seize photos of different resident house objects, analyze them, and autonomously execute exact maneuvers to watch the objects.
U.S. officers usually describe the purpose as “maneuvering with out remorse,” or the power to reposition satellites on orbit with out jeopardizing the mission or losing pricey gasoline.
On the business aspect, Astranis signed on for a 2027 mission that will see its MicroGEO satellites launched to LEO on a SpaceX Falcon 9 rocket after which delivered to geostationary orbit in lower than 24 hours by Helios. That mission profile is tremendous precious to Astranis, as it should permit the corporate to dramatically speed up satellite tv for pc activation dates for purchasers ready for his or her satellite tv for pc broadband companies right here on Earth.
Lastly, Impulse signed a multi-launch settlement with France’s Infinite Orbits to hold a number of satellite tv for pc servicing spacecraft to GEO through a ride-share program referred to as Caravan. Impulse says the Caravan providing will ship a number of small satellites on the identical time, a lot as SpaceX’s ride-share program lets firms break up the price of a launch. The primary Caravan mission is absolutely booked for 2026, Impulse mentioned.
Lately, the house trade’s explosive progress has largely centered on LEO as operators shifted to smaller, cheaper satellites for purposes in communications and distant sensing. But when Impulse has its approach, the following part of progress will likely be in GEO.
