- A Reddit user appears to have posted the first unambiguous photos of ground devices that connect to SpaceX’s fleet of internet-beaming Starlink satellites.
- The person said they drove by the SpaceX site near Merrillan, Wisconsin, and used a large telephoto lens to photograph the antennas.
- The devices closely match prior descriptions of them by Elon Musk, SpaceX’s founder and CEO. A label on the antennas also describes the hardware as prototypes and property of SpaceX.
- Though Musk has said Starlink could eventually net SpaceX tens of billions of dollars per year, he recently said that bringing down the cost of subscriber antennas, called user terminals, may be the project’s biggest hurdle.

A SpaceX fan who lives near Merrillan, Wisconsin, has apparently seen the aerospace company’s future on a rural gravel lot across the road from rows of grain corn.
The photos, postedSaturday by the Reddit user Darkpenguin22, may be the clearest images yet of ground antennas described by SpaceX in federal filings for Starlink: a growing fleet of internet-beaming satellites that may orbit Earth by the tens of thousands before the end of the decade.
If Starlink pans out as described by SpaceX founder Elon Musk, the aerospace company may net tens of billions of dollars per year by getting people online with high-speed, low-lag internet from almost anywhere on the planet’s surface.
While SpaceX has posted plenty of photos and videos of its roughly 570-pound, desk-sized satellites, the company has yet to reveal any of its Starlink ground-segment hardware.
SpaceX did not respond to Business Insider’s request for comment on the images and their contents. However, the pictures appear to show authentic prototypes capable of talking to overflying Starlink satellites. The site also matches satellite imagery for a SpaceX testing location in an April 29 notice by the Federal Communications Commission, and a magnified view of the label on the devices says the units are prototypes and SpaceX property.
The pictures, republished here with permission, were taken with a high-power telephoto lens from afar. They show two flavours of apparent Starlink antennas: a roughly 5-foot-diameter bulbous white radome, which protects ground-station electronics inside, and a much smaller and sleeker user terminal Musk has described as a “UFO on a stick.”
There have been previous sightings of apparent Starlink prototype ground equipment – such as in Boca Chica, Texas, where SpaceX is developing its new Starship launch system – but the new images most clearly show the hardware.
“I just happen to live nearby, so going there to take some pictures myself was an easy way to contribute to the community,” Darkpenguin22, who requested anonymity to maintain their privacy, told Business Insider in a message. “I’m a longtime SpaceX and Tesla fan and work in IT as a sysadmin, so have been closely following Starlink developments for both personal and professional/business purposes.”
The person added: “Could potentially become a very competitive alternative for corporate site-to-site links, at least in less population dense parts of the country/world. I also see it as key to enabling efficient remote working for those of us who prefer a more rural lifestyle.”
A ‘UFO on a stick’ revealed
In its earliest phase, SpaceX plans to launch nearly 1,600 Starlink satellites to an altitude of about 340 miles above Earth. To that end, the company has rocketed 62 experimental and 480 operational satellites into space – though it is attempting to send up a new batch of about 60 satellites roughly every two weeks.
Gwynne Shotwell, the president and chief operating officer of SpaceX, told Irene Klotz of Aviation Week in May that the company would “roll out service in a more public way” after launching more than 800 spacecraft, which the company is on track to achieve by fall.
The first phase of satellites will orbit about 64 times closer than a typical internet-beaming satellite, thus they could be capable of providing nearly lagless internet. If SpaceX can prove its case to the FCC, the company may qualify for billions in federal subsidies geared toward providing internet to areas with low-quality or nonexistent broadband service.
Key to that effort, however, are the devices companies and people will use to upload and download data to and from Starlink.
The larger ground stations would be used in key locations to help shuttle internet traffic to and from the Starlink network. Meanwhile, Starlink beta testers and later individual subscribers would use the smaller terminals to log on to the network.
Musk in 2015 said the user terminals would be about the size of a medium pizza. Earlier this year, Musk further described a user terminal as “a thin, flat, round UFO on a stick” that would use motors to self-adjust to an “optimal angle to view sky” and talk to SpaceX’s fleet of orbiting Starlink satellites.
All that’s required to set them up, the CEO said, is to plug them in and point them at the sky. (“These instructions work in either order. No training required,” he tweeted on January 7.)
The images of the satellite dishes shared on Reddit clearly fit the description. A zoomed-in part of one photo (not shown) also shows a label with a serial number and a notice that says:
Property of SpaceX
Prototype – Not for sale or lease This unit is intended for demonstrations use only. This device has not been authorised as required by the rules of the Federal Communications Commission. This device is not, and may not be, offered for sale or lease, or sold or leased, until authorization is obtained. Therefore, ownership must remain with SpaceX.
The size of the device also aligns with SpaceX patents for a phased-array antenna component that’s apparently inside each user terminal.
The phased array, designed to rapidly track and communicate with in-view satellites, is necessary for Starlink because the spacecraft move overhead so quickly. Bowl-shaped dishes that don’t move and point to one part of the sky, like those used to aim at a traditional TV or internet satellite, wouldn’t suffice for keeping an uninterrupted connection. A platter of phase shifters, however, can work together to electronically and almost instantly steer a transmission beam from one satellite to another.
SpaceX in February 2018 filed US and world patents for a “distributed phase shifter array system and method.” The US version is pending, and the world version is still under review, so neither the US Patent Office nor World Intellectual Property Organisation has yet granted SpaceX a patent.
But Starlink has a long road to profitability
Musk is looking to Starlink as a colossal revenue stream to help fund SpaceX’s planned quest of Mars. The company is authorised to launch nearly 12,000 of the satellites, though it’s seeking to launch a total of about 42,000.
“For the system to be economically viable, it’s really on the order of 1,000 satellites,” Musk told Business Insider of Starlink during a press call on May 15, 2019. “If we’re putting a lot more satellites than that in orbit, that’s actually a very good thing. It means there’s a lot of demand for the system.”
But while Starlink may complete beta tests of the system and start transitioning to public service before the end of 2020, turning the project into a moneymaker could take much longer.
Musk told Aviation Week in May that bringing down the cost of user terminals – which would connect subscribers to orbiting Starlink satellites – remains a major hurdle. Phased-array antenna components cost about $US1,500, though Musk wants to sell customers a “UFO on a stick” for about $US200 to $US300.
“I think the biggest challenge will be with the user terminal and getting the user terminal cost to be … affordable,” he told Aviation Week. “That will take us a few years to really solve.”
The apparent conflict between a public-service rollout before 2021 and affordable user terminals around 2023 suggests the cost of the devices may at first be significantly subsidized by SpaceX to allow the company to build a customer base for the network.
