SpaceX CEO Elon Musk reveals next-generation Starlink satellite details

Published

on

SpaceX CEO Elon Musk has revealed the first technical details about the company’s next-generation Starlink ‘Gen2’ satellite design, confirming that it will far outmatch the current generation of satellites by almost every measure.

Speaking in an onsite interview and Starbase tour with YouTuber Tim Dodd (The Everyday Astronaut), Musk – largely unprovoked – revealed that SpaceX has already built at least one functional Starlink Gen2/V2.0 satellite prototype and shipped it to the South Texas Starship factory, where it is currently being stored. More importantly, Musk also provided the first direct specifications for the next-generation spacecraft, stating that each Starlink V2.0 satellite will weigh about 1.25 tons (~2750 lb), measure about seven meters (~23 ft) long, and be almost an order of magnitude more capable than the “Starlink 1” satellites they’ll ultimately supersede.

Almost ten months after SpaceX first revealed its updated plans for a next-generation, 30,000-satellite constellation, those details have confirmed a few key points of speculation about the future of Starlink.

Musk’s Starlink comments begin around nine minutes in.

Back in August 2021, I surmised that just like it has with Falcon 9, SpaceX would again try to optimize its new Starlink V2.0 satellite design to take maximum advantage of Starship’s launch performance. In an updated Starlink Gen2 filing, the company conveniently revealed that a version of the constellation optimized for Starship would be structured such that the rocket could launch an entire orbital plane (one ring of satellites spaced evenly around the Earth) in one go. In that constellation variant, all but ~500 (1.5%) of almost 30,000 spacecraft would be stationed in planes of 110 or 120 satellites, meaning that it was safe to assume that SpaceX meant that every Starship would nominally carry 110-120 satellites. Using Musk’s latest optimistic Starship performance estimate of 150 tons to low Earth orbit (LEO), that all but guaranteed that a Starship-optimized Starlink V2.0 satellite would weigh up to 1250 kilograms.

Musk has now explicitly confirmed that each Starlink V2.0 satellite will weigh… “about one and a quarter tons” or 1250 kilograms. Starlink V1.0 and V1.5 satellites weigh around 260 and 310 kilograms, respectively, meaning that Starlink V2.0 satellites will be about a bit more than four times heavier than V1.5 and a bit less than five times heavier than V1.0.

Musk also revealed that V2.0 satellites will be “almost an order of magnitude more capable than Starlink 1.” He refused to call that capability bandwidth or throughput, the traditional method of describing a communication satellite’s total performance, but Starlink V1.0 satellites are believed to have a total bandwidth of 18 gigabits per second (18 Gbps). As of today, it’s unknown if Starlink V1.5 – a significant upgrade – also added more bandwidth, nor if Musk was referring to that latest Starlink V1.x iteration. But even if he was comparing V2.0 with the earliest V1.0 satellites, it’s possible that each Starlink V2.0 satellite could add around 140-160 Gbps to the 30,000-satellite constellation.

Ultimately, specific numbers aren’t needed to emphasize the importance of the details Musk provided. If true, they mean that Starlink V2.0 will pack roughly twice as much usable bandwidth into a given unit of satellite mass compared to V1.x. Combined with the fact that Starship could offer ~10 times as much performance to LEO as Falcon 9, a single Starship launch could theoretically expand total network capacity roughly twenty times more than one Falcon 9 launch. For example, each Falcon 9 launch of 60 260-kilogram Starlink V1.0 satellites added about 1080 Gbps of instantaneous bandwidth to the constellation. A Starship launch of 120 1250-kilogram Starlink V2.0 satellites could add around 19,000 Gbps (19 terabits per second).

Even despite those massive advantages, SpaceX’s Starlink Gen2 ambitions still leave it no slack whatsoever. If the FCC approves its license request, SpaceX would need to launch half of the constellation within six years – equivalent to around 130 Starship launches or 22 Starship launches per year. In comparison, Falcon 9 – a rocket that’s ten times smaller, less reusable, and has been flying since 2010 – did not achieve 22 launches in one year until 2020. For Starship to have any hope of achieving the cadence Starlink Gen2 requires, SpaceX would have to ramp up launches of the largest rocket ever built at a truly miraculous pace and suffer very few failures or setbacks along the way.

As immense as the challenge may be, the potential rewards are just as high. A constellation of 30,000 Starlink V2.0 satellites – if spaced evenly around the Earth – could have a total bandwidth of ~1250 terabits per second (Tbps) available over land (excluding Antarctica) at any given second. Even if half of that bandwidth is needed for backhaul and routing, the total installed bandwidth of global internet infrastructure was estimated to be 600 Tbps in 2020. Starlink will always be bottlenecked by the number of satellites that can be simultaneously available over any single point on Earth, so the constellation will never be able to match a ground network 1:1 with the same installed capacity, but it’s safe to assume that Starlink Gen2 could serve tens or even hundreds of millions of users located anywhere on Earth if SpaceX is able to build it.

Tesla investors will be shocked by Jim Cramer’s latest assessment

Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.

When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.

Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.

He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.

Now, he is back to being a bull.

Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.

Jensen Huang’s Tesla Narrative

Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.

“It’s not a car company,” he said.

He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:

“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Robotaxi Launch

Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.

There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.

He said:

“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”

It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.

Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla already has nearly 12,000 Supercharger piles across mainland China. However, the company just initiated the rollout of the ultra-fast V4 Superchargers in China for the first time, bringing its quick-charging piles to the country for the first time since their launch last year.

The first batch of V4 Superchargers is now officially up and running in China, the company announced in a post on Chinese social media outlet Weibo today.

Tesla China teases arrival of V4 Superchargers in 2025

The company said in the post:

“The first batch of Tesla V4 Superchargers are online. Covering more service areas, high-speed charging is more convenient, and six-layer powerful protection such as rain and waterproof makes charging very safe. Simultaneously open to non-Tesla vehicles, and other brands of vehicles can also be charged. There are more than 70,000 Tesla Superchargers worldwide. The charging network layout covers 100% of the provincial capitals and municipalities in mainland China. More V4 Superchargers will be put into use across the country. Optimize the charging experience and improve energy replenishment efficiency. Tesla will accompany you to the mountains, rivers, lakes, and seas with pure electricity!”

The first V4 Superchargers Tesla installed in China are available in four cities across the country: Shanghai, Zhejiang, Gansu, and Chongqing.

Tesla has over 70,000 Superchargers worldwide. It is the most expansive and robust EV charging network in the world. It’s the main reason why so many companies have chosen to adopt Tesla’s charging connector in North America and Europe.

In China, some EVs can use Tesla Superchargers as well.

The V4 Supercharger is capable of charging vehicles at speeds of up to 325kW for vehicles in North America. This equates to over 1,000 miles per hour of charging.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi

Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.

Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.

A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.

The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.

The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.

With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.

CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”

Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.

Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.

Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.

For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.
