SpaceX’s second Starlink Gen2 launch could set payload record [webcast]

Published

on

SpaceX’s second Starlink Gen2 launch will carry 56 satellites, potentially making it the heaviest payload the company has ever launched.

At 9:30 am EST, SpaceX completed a static fire of the two-stage Falcon 9 rocket assigned to launch its next Starlink mission. Half an hour later, SpaceX confirmed that the rocket performed well and is scheduled to launch no earlier than 4:32 am EST (09:32 UTC) on Thursday, January 26th. SpaceX didn’t state the mission’s purpose, but shorthand (“sl5-2”) used in an official website URL implies that it will be the second launch for its Starlink Gen2 satellite constellation.

SpaceX also reported that Starlink 5-2 will carry 56 satellites, meaning that the mission could set a new Falcon 9 payload record.

56 is not a record number of satellites for a SpaceX launch or a Starlink launch. SpaceX has launched a record 143 rideshare payloads at once, and the company routinely launched 60 Starlink satellites at a time throughout 2019, 2020, and part of 2021. But those Starlink satellites were the first versions (V1.0) of the spacecraft and weighed either 227 or 260 kilograms (500/570 lbs) apiece.

In the second half of 2021, SpaceX began launching new Starlink V1.5 satellites. Outfitted with new laser links (optical terminals) and other general upgrades, the new satellites reportedly weigh 303, 307, or 309 kilograms (668, 676, or 681 lb) each. The heavier design forced SpaceX to slightly reduce the number of satellites each launch could carry. After some optimization, SpaceX regularly launches up to 54 Starlink V1.5 satellites at a time, down from 60 V1.0 satellites.

The number of satellites may be smaller, but the mass of the payload launched has never been higher. SpaceX last broke Falcon 9’s payload mass record in August 2022, when it launched 54 Starlink V1.5 satellites for the first time. The payload reportedly weighed 16.7 tons (~36,800 lb), breaking the previous record of 16.25 tons by about 3%. The heaviest 60-satellite Starlink V1.0 payload weighed around 15.6 tons (~34,400 lb).

Now, SpaceX says it will launch 56 Starlink satellites – likely heavier V1.5 variants – at once. If SpaceX hasn’t reduced the weight of each satellite, the payload could weigh anywhere from 16.97 to 17.3 tons (37,400-38,200 lb). Starlink 5-2 is targeting the same orbit as Starlink 5-1, which carried 54 satellites. The likeliest explanation for the heavier payload appears to be another iterative improvement to Falcon 9.

As SpaceX gains confidence in and experience with Falcon 9, it’s been able to tweak the timing of certain launch events, raise performance limits, and reduce certain margins. If Starlink 5-2’s Starlink satellites are unchanged, SpaceX’s tweaks will have collectively boosted Falcon 9’s performance by ~10% (15.6 to ~17 tons) in two years.

Gen1, V1.0, V1.5, Gen2, V2.0

Starlink 5-2 also continues the trend of confusion created by the company’s first Starlink Gen2 launch, which it deemed Starlink 5-1. The naming scheme implied that the satellites were a continuation of the company’s first constellation, Starlink Gen1, but SpaceX confirmed that they were actually the first Starlink Gen2 satellites. That SpaceX is launching 54 (and now 56) satellites also confirms that they are likely the same V1.5 satellites the company has been launching for 18 months.

SpaceX CEO Elon Musk has outright stated that the company could go bankrupt if it couldn’t begin launching much larger Starlink V2.0 satellites on its Starship rocket in the near future. Instead, SpaceX is doing the exact opposite and is populating its Starlink Gen2 constellation with Gen1-sized satellites. It’s unclear when SpaceX will begin launching the larger Starlink V2.0 satellites that were meant to be the mainstay of the Gen2 constellation.

Bank of America raises Tesla PT to $471, citing Robotaxi and Optimus potential

The firm also kept a Neutral rating on the electric vehicle maker, citing strong progress in autonomy and robotics.

Bank of America has raised its Tesla (NASDAQ:TSLA) price target by 38% to $471, up from $341 per share.

The firm also kept a Neutral rating on the electric vehicle maker, citing strong progress in autonomy and robotics.

Robotaxi and Optimus momentum

Bank of America analyst Federico Merendi noted that the firm’s price target increase reflects Tesla’s growing potential in its Robotaxi and Optimus programs, among other factors. BofA’s updated valuation is based on a sum-of-the-parts (SOTP) model extending through 2040, which shows the Robotaxi platform accounting for 45% of total value. The model also shows Tesla’s humanoid robot Optimus contributing 19%, and Full Self-Driving (FSD) and the Energy segment adding 17% and 6% respectively.

“Overall, we find that TSLA’s core automotive business represents around 12% of the total value while robotaxi is 45%, FSD is 17%, Energy Generation & Storage is around 6% and Optimus is 19%,” the Bank of America analyst noted.

Still a Neutral rating

Despite recognizing long-term potential in AI-driven verticals, Merendi’s team maintained a Neutral rating, suggesting that much of the optimism is already priced into Tesla’s valuation.

“Our PO revision is driven by a lower cost of equity capital, better Robotaxi progress, and a higher valuation for Optimus to account for the potential entrance into international markets,” the analyst stated.

Interestingly enough, Tesla’s core automotive business, which contributes the lion’s share of the company’s operations today, represents just 12% of total value in BofA’s model.

Tesla Model Y on FSD saves couple after encountering King of edge cases

Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.

A South Australian Tesla driver is thanking his Model Y’s Full Self-Driving system after a mysterious object, possibly a meteorite, slammed into his car’s windshield while it had FSD engaged. 

The impact sent hot glass fragments flying through the cabin as the vehicle continued driving without human input through the darkness. Experts have noted that if confirmed, this could be the world’s first recorded meteorite collision involving a Tesla.

The Tesla owner was enjoying a quiet drive home when they hit the king of edge cases

Veterinarian Dr. Andrew Melville-Smith and his wife were traveling north on Augusta Highway on the night of October 19 when a sudden blast struck their newly delivered Model Y. At the time, it was clear, pitch black night, and Dr. Melville-Smith and his wife were just listening to a podcast while FSD was operating the vehicle, as noted in a Yahoo News report. 

Suddenly, something hit the Tesla’s windshield. “Then there was, (what) I can only describe as a very, very violent explosion. The whole inside of the car was literally blasted with glass fragments. It was full of white smoke, and it smelled like the car was on fire,” Dr. Melville-Smith stated. 

The vet stated that he and his wife were stunned for a good 10 seconds, and for a bit, he and his wife thought they had crashed. Images of the crash’s aftermath showed a massive crack on the Tesla’s windshield, which Dr. Melville-Smith noted was hot to the touch. The object that hit the Tesla’s windshield was so hot that part of the vehicle’s windshield was partly melted.

FSD kept driving despite the possible meteorite strike

Thankfully, the Tesla was operating with its FSD (Supervised) system engaged at the time. Thus, despite the vehicle being hit by what might be a literal meteorite, and despite Dr. Melville-Smith and his wife being stunned because of the impact, their Tesla just kept driving steadily. 

“I thought we’d had an accident, but then I looked at the screen and went ‘Oh, we’re still driving. We were moving around, so it obviously thought we were paying attention, and it was happy to keep driving to Port Augusta. After we pulled over, we saw the big crater in the windscreen,” the vet said. 

The South Australian Museum is now examining the case, with geologist Dr. Kieran Meaney stating the scorched glass and heat damage do suggest a potential meteorite strike. “The little detail that’s really selling it for me at the moment is that whatever it was that hit the windscreen seems to have been very hot,” Meaney explained. However, the object has yet to be recovered.

“Foundation:” Elon Musk wants to send a record of Grokipedia to space

The idea sounds outlandish, though it is also something that is in character for the CEO.

Elon Musk has announced one of his latest initiatives, and it is every bit as sci-fi as it is surprisingly grounded. In a post on X, Musk stated that Grokipedia, xAI’s new open-source encyclopedia, will be etched into stable oxide and launched into space. 

The idea sounds outlandish, though it is also something that is in character for the CEO.

Preserving human knowledge among the stars

Musk posted his plan following the launch of Grokipedia’s V0.1’s iteration. The CEO congratulated the xAI team for the online encyclopedia’s launch, though he also stated that the goal for Grokipedia is to create an open-source collection of knowledge. This would then be distributed to the cosmos.

“Nice work by the xAI team on Grokipedia! The goal here is to create an open source, comprehensive collection of all knowledge. Then place copies of that etched in a stable oxide in orbit, the Moon, and Mars to preserve it for the future. Foundation,” Musk wrote in his post.

While seemingly outlandish, this is not the first time that a record of human knowledge of sorts was sent out to space. In 1977, the Voyager Golden Record was launched aboard NASA’s Voyager 1 and 2 spacecraft. The record contains sounds and images that ere aggregated to portray the diversity of the Earth’s culture. Of course, Musk’s plan with Grokipedia, is infinitely more ambitious.

Grokipedia and AI neutrality

Musk launched Grokipedia as an AI-driven alternative to Wikipedia, designed to eliminate the human biases that could affect conventional online knowledge platforms. The system is powered by xAI’s Grok, which scrape and summarize information from across the internet, offering balanced and nuanced coverage of topics ranging from science and technology to culture and politics.

Unlike Wikipedia’s human-edited format, Grokipedia would be able to evolve through machine learning, reading vastly more material than any editorial team could. Early testers, including Wikipedia co-founder Larry Sanger, praised its initial version as “very OK” and potentially more neutral than Wikipedia. Musk agreed, stating that even in its V0.1 form, Grokipedia is “already better than Wikipedia.”
