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 usually a months-long transit right into a matter of hours.
Within the span of per 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 take care of 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 improvement of the Merlin and Raptor engines. He left SpaceX in 2020 and began Impulse to construct out in-space transport companies targeted on last-mile supply in low Earth orbit (LEO) — which is usually 100 to 1,200 miles above Earth — and ultra-fast satellite tv for pc transport to GEO.
The frequent denominator throughout these missions is Helios, Impulse’s methane-oxygen kick stage. A kick stage is actually a small rocket engine system that rides on a bigger rocket after which fires its personal engine – on this case, a robust engine known as Deneb – to propel spacecraft to their last vacation spot.
Helios is supposed to be the “identical day” courier from LEO to greater altitude orbits. If it performs as marketed, business operators may attain greater orbits a lot sooner, and the Division of Protection may maneuver extra rapidly in an more and more contested area of house.
GEO isn’t simply far-off. 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 discipline — take care of latency in long-distance communication, and preserve their exact place.
The partnership between Anduril and Impulse may show particularly profitable. The pair will collectively construct a demo satellite tv for pc for rendezvous and proximity operations — a functionality that permits spacecraft to strategy and examine different objects in orbit — which the Area Drive has recognized as vital for house area consciousness and deterrence.

Impulse is supplying the spacecraft – known 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 aimed toward monitoring and high-precision navigation.
As a part of the demo, Helios will ferry the spacecraft to GEO in underneath a day, after which the mission goals to seize photographs of different resident house objects, analyze them, and autonomously execute exact maneuvers to watch the objects.
U.S. officers usually describe the aim as “maneuvering with out remorse,” or the power to reposition satellites on orbit with out jeopardizing the mission or losing pricey gas.
On the business aspect, Astranis signed on for a 2027 mission that may 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 enable the corporate to dramatically speed up satellite tv for pc activation dates for patrons 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 known 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 corporations cut up the price of a launch. The primary Caravan mission is totally booked for 2026, Impulse mentioned.
In recent times, the house trade’s explosive progress has largely targeted on LEO as operators shifted to smaller, inexpensive satellites for purposes in communications and distant sensing. But when Impulse has its means, the following section of progress will probably be in GEO.
