JUPITER 3 (ECHOSTAR 24)

Jupiter 3, cataloged under NORAD ID 57479 and international designator 2023-108A, is a large commercial communications satellite operated by Hughes Network Systems and owned by the United States. Launched on July 28, 2023, the spacecraft occupies a geostationary orbit roughly 35,800 kilometers above the equator, where it remains effectively stationary relative to the ground below. Built by Maxar Technologies and weighing approximately 5,817 kilograms at launch, Jupiter 3 is among the heaviest commercial communications satellites ever placed into orbit. Also designated EchoStar 24 under its operator's naming convention, the satellite extends Hughes's broadband internet infrastructure across the Western Hemisphere, delivering high-speed connectivity to residential and business customers throughout North and South America.

Mission and Purpose

The core mission of Jupiter 3 is to provide satellite-based broadband internet service to subscribers across North and South America. Hughes Network Systems, a subsidiary of EchoStar Corporation, operates the satellite as part of its Jupiter satellite internet platform — a series of high-throughput spacecraft designed to bring competitive internet speeds to areas that are poorly served by terrestrial infrastructure such as fiber or cable.

Operating under the Hughes branding, the satellite delivers download speeds reaching up to 100 Mbps to end users, a figure that places it firmly in the category of high-throughput satellites (HTS). This performance is made possible through the use of spot-beam technology, where the satellite's total bandwidth is divided among many narrow, geographically focused beams rather than a single wide coverage footprint. By reusing radio frequency spectrum across many individual beams, high-throughput satellites like Jupiter 3 can offer dramatically higher aggregate capacity than earlier generations of broadband satellites.

The populations most directly served by Jupiter 3 are those living in rural, remote, or underserved regions where conventional ground-based broadband is economically or physically impractical to deploy. In such areas, satellite internet has historically represented the only viable path to connectivity, and a satellite with Jupiter 3's capacity can meaningfully expand access to education, commerce, telemedicine, and communication for households and communities that have long been on the wrong side of the digital divide.

Hughes's Jupiter platform also serves aviation, maritime, and enterprise customers who require reliable, wide-area connectivity that moves with them or spans regions too vast for any single terrestrial network to cover. While the specific service breakdown for Jupiter 3 is not publicly recorded in the satellite catalog, the platform's design philosophy has consistently targeted this mix of residential and mobility markets.

Orbit and Tracking

Jupiter 3 resides in a geostationary Earth orbit (GEO), the band of space approximately 35,786 kilometers above the equator where an object's orbital period matches the Earth's rotational period almost exactly. The satellite's tracked apogee stands at 35,800 kilometers and its perigee at 35,790 kilometers, indicating an exceptionally circular orbit with virtually no eccentricity — a hallmark of an operational geostationary spacecraft that has completed its drift to its assigned longitudinal slot. Its inclination is recorded at 0.0 degrees, confirming that the orbit lies directly over the equatorial plane.

The orbital period of Jupiter 3 is 1,436.2 minutes — just under 24 hours — which is what allows the satellite to remain fixed over a single point on the Earth's surface as seen from the ground. This property is fundamental to the economics and engineering of broadband satellite services: a dish antenna installed at a subscriber's home can point at a fixed position in the sky and maintain a stable link without any mechanical tracking. For a satellite providing internet service to millions of widely dispersed subscribers, this is a practical necessity.

Because geostationary satellites orbit at such extreme altitudes, the round-trip signal delay — or latency — is significantly higher than what users experience on terrestrial networks, typically on the order of 600 milliseconds or more for a full round trip. This is a well-understood characteristic of GEO-based internet services and has implications for real-time applications like online gaming or certain voice protocols, though it does not impede most forms of web browsing, video streaming, or file transfer.

Jupiter 3 is tracked continuously by the United States Space Surveillance Network, which maintains its orbital elements under NORAD catalog number 57479. As of the time of writing, the satellite remains in orbit and operational. Its object type is classified as a payload, distinguishing it from rocket bodies and debris objects that may share proximity in the geostationary belt.

Design and Operator

Jupiter 3 was manufactured by Maxar Technologies, a Colorado-based space technology company with a long history of building large commercial communications satellites. Maxar's heritage in geostationary satellite construction — previously under the SSL (Space Systems Loral) brand before the corporate rebranding — includes many of the most capable high-throughput satellites in service today. The company's GEO satellite bus platforms are engineered for high power output and long operational lifespans, characteristics that are essential for a satellite intended to generate a commercial return over many years.

At a launch mass of 5,817 kilograms, Jupiter 3 is a very large spacecraft by any measure. In the geostationary arc, satellite mass is a direct indicator of complexity and capability: heavier satellites typically carry more transponders, larger solar arrays, more powerful amplifiers, and greater amounts of onboard fuel for station-keeping. The fuel fraction of a geostationary satellite's mass at launch is substantial, as the spacecraft must use its own propulsion system continuously throughout its life to counteract the gravitational perturbations from the Moon, the Sun, and the slight oblateness of the Earth that would otherwise cause its orbit to drift and incline over time.

The satellite was launched on July 28, 2023, with liftoff occurring at 20:00 Eastern Daylight Time. The choice of a July 2023 launch placed Jupiter 3 among the cohort of very large commercial GEO satellites that represent the culmination of a decade-long push in the industry toward ever-greater per-satellite capacity, a trend driven partly by competition from low-Earth orbit broadband constellations.

The operating entity, Hughes Network Systems, is headquartered in the United States and has been a prominent player in the satellite internet market for decades. Hughes pioneered the consumer satellite broadband segment with its DirecWay and HughesNet service lines and has continued to invest in successive generations of dedicated high-capacity satellites. EchoStar Corporation, the parent company, provides the corporate umbrella under which both the Hughes retail brand and the EchoStar satellite designations coexist — hence Jupiter 3's dual identity as both a Hughes service platform and EchoStar 24 in the fleet numbering system.

Current Status and Significance

Jupiter 3 represents a significant investment in geostationary broadband capacity at a moment when the satellite internet industry is undergoing considerable competitive pressure and transformation. The emergence of low-Earth orbit broadband constellations has prompted established GEO operators to respond with larger, more capable satellites that can offer higher speeds and serve more subscribers per spacecraft. Jupiter 3 fits squarely within that strategic response: a single very large satellite that concentrates enormous capacity in a geostationary slot, leveraging the inherent advantage of GEO's fixed sky position and the existing infrastructure of millions of installed subscriber dishes.

The satellite's mass places it in rare company among commercial communications satellites, and its addition to Hughes's fleet meaningfully increases the total throughput available to the operator's North and South American customer base. For rural subscribers in particular — farming communities, small towns, remote indigenous settlements, and isolated households across two continents — the added capacity translates directly into either improved service quality for existing customers or newly available service for those who were previously beyond the reach of prior satellites.

Specific details regarding Jupiter 3's operational status, service commencement date, assigned orbital longitude, or current subscriber metrics are not publicly recorded in the satellite catalog, and this article does not speculate on those particulars. What is documented is that the spacecraft remains in orbit as of the catalog data available, continuing to hold its geostationary position above the equator with an inclination of 0.0 degrees and a nearly perfect circular orbit.

In the broader context of the geostationary arc, Jupiter 3 joins a long lineage of Hughes-operated satellites that have provided connectivity across the Americas, contributing to a commercial legacy that stretches back to the earliest days of satellite telecommunications. Its placement by Maxar Technologies continues a manufacturing relationship that has produced some of the most capable commercial satellites in the current fleet, and its operation by Hughes ensures that the capacity it carries is directed toward one of the satellite industry's most enduring and socially consequential missions: connecting the unconnected.
