SpaceX Starlink engineers take questions in Reddit AMA—here are highlights

SpaceX Starlink engineers answered questions in a Reddit AMA (Ask Me Anything) on Saturday, covering topics such as data caps (which they hope to never implement), when the public beta will expand to more users, and how the satellite-broadband service will expand and change in the future.

“Starlink is an extremely flexible system and will get better over time as we make the software smarter. Latency, bandwidth, and reliability can all be improved significantly,” the engineers wrote under the Reddit username “DishyMcFlatface,” which is also SpaceX’s nickname for the Starlink satellite dish.

Here are some highlights from the AMA.

No data caps “at this time”

When asked if users will ever face data caps, the Starlink team gave a vague answer: “At this time, the Starlink beta service does not have data caps.”

While that response covered the present but not the future, a subsequent comment from DishyMcFlatface gave a more detailed answer that suggests SpaceX is trying to avoid data caps:

So we really don’t want to implement restrictive data caps like people have encountered with satellite Internet in the past. Right now we’re still trying to figure a lot of stuff out—we might have to do something in the future to prevent abuse and just ensure that everyone else gets quality service.

Expanded beta in January—no bribes required

Many people who haven’t been able to get the Starlink beta are eagerly awaiting updates on availability, and the AMA provided an answer. SpaceX is “steadily increasing network access over time to bring in as many people as possible,” the Starlink team wrote. “Notably, we’re planning to move from a limited beta to a wider beta in late January, should give more users an opportunity to participate.”

SpaceX CEO Elon Musk gave a similar update on Twitter a few weeks ago when a user asked when the beta will come to Florida. “Lower-latitude states need more satellites in position, so probably January,” Musk wrote at the time.

As before, people hoping to get Starlink can enter their email and service address on the Starlink website and hope to hear back. Bribes apparently won’t help. When one Reddit user asked, “How are beta users chosen and what’s a good bribe amount?” the Starlink team answered, “No bribes necessary, our goal is serve everyone eventually.”

More engineers needed

The Starlink team told Reddit users several times that SpaceX is looking for more engineers. In the answer about when the beta will expand, DishyMcFlatface wrote, “If you really want to help drive that, the best thing you can do is send great software engineers over to Starlink to help make it happen.”

Over a dozen jobs in Starlink production design, product design, and software are available, and links to the job posts can be found in this DishyMcFlatface comment. “We are super excited about the initial response and future potential of Starlink, but we still have a ton to learn,” the Starlink team wrote. “If you know any great people who can help us with that, please have them email their resume to starlink@spacex.com.”

Will Starlink work away from home?

A few weeks ago, we wrote about a Starlink beta user who took the satellite dish and a portable power supply to a national forest in Idaho, where he was able to get fast Internet service. But that doesn’t mean you can take the dish just anywhere, as SpaceX currently only promises that it will work at each beta user’s service address.

One Reddit user who lives and works on a boat docked in South Florida wanted to know if Starlink will provide service on the open seas. “A mobile system that gives me reliable connectivity will truly set me free to roam the coastal US, Bahamas, and eventually beyond,” the user wrote.

Starlink answered:

Right now, we can only deliver service at the address you sign up with on starlink.com. You might get lucky if you try to use Starlink in nearby locations, but service quality may be worse.

Mobility options—including moving your Starlink to different service addresses (or places that don’t even have addresses!)—is coming once we are able to increase our coverage by launching more satellites & rolling out new software.

SpaceX recently asked the Federal Communications Commission for permission to test Starlink user terminals “on seagoing platforms” and on private jets.

Storms and extreme temperatures

A Reddit user asked if the satellite dish will work in heavy wind, such as when mounted “on the tail of a flatbed trailer flying down the interstate into a collapsing thunderstorm.” The SpaceX team said that is not a recommended use and that the “dish is not designed for tropical storms, tornadoes, etc.”

One Reddit user who lives in Canada asked if the dish will work in temperatures as low as 45° below zero Celsius (that’s 49° below in Fahrenheit). Starlink engineers responded that the dish is certified to operate from 30° below zero to 40° above zero on the Celsius scale (that’s 22° below zero up to 104°F). SpaceX has performed “testing down to these cold temperatures with no issues.”

Starlink satellite dishes “have self-heating capabilities to deal with a variety of weather conditions,” the team also said. In the coming weeks and months, they plan to deploy software updates that will “upgrade our snow melting ability.”
