Following a successful May 4th launch atop Falcon 9, SpaceX’s latest Cargo Dragon spacecraft is just a few hours away from starting its International Space Station (ISS) berthing sequence.

Scheduled to begin around 5:30 am EDT (09:30 UTC), SpaceX operations staff will command Dragon to continue a cautious ISS approach. Several hours later, the spacecraft will be quite literally grabbed by station astronauts and gently berthed with one of the space station’s several Common Berthing Mechanism (CBM) ports. Once Cargo Dragon has been safely joined with the ISS, the station’s crew of astronauts can begin the intensive process of unpacking more than 1500 kg (3300 lb) of pressurized cargo, including dozens of time-sensitive and complex science experiments.

Aside from the 1.5 tons of cargo contained inside Dragon’s climate-controlled cabin, ISS astronauts and ground-based NASA controllers will again use the space station’s robotic Canadarm2 manipulator to extract two large unpressurized payloads from Dragon’s trunk. The ‘flagship’ instrument of CRS-17 is NASA’s Orbiting Carbon Observatory-3 (OCO-3), an upgraded follow-on to OCO-2 that should dramatically improve the quantity and quality of data available on the distribution of carbon in the Earth’s atmosphere. The second trunk-stashed payload is known as STP-H6 and is carrying around half a dozen distinct experiments.

Both STP-H6 and OCO-3 will be installed on the outside of the space station with the help of Canadarm2, an extremely useful capability that limits the need for astronauts to suit up and perform risky and time-consuming EVAs (extra-vehicular activities) outside the ISS. With its trunk emptied, Cargo Dragon will eventually discard the section to burn up in Earth’s atmosphere just before the reusable capsule begins its own reentry.

Unlike several other spacecraft with service sections, both proposed, flying, or retired, SpaceX’s Dragon spacecraft strive to minimize the complexity and cost of their expendable service sections. For both Cargo and Crew Dragon, the trunk serves as a structural adapter for unpressurized payloads and the Falcon-Dragon interface, hosts solar arrays and radiators, and doesn’t do much else. All propulsion, plumbing, and major avionics are kept within the capsule to maximize reusability.

Defining “slow and steady”

The process of berthing or docking with the ISS is a fundamentally cautious thing, developed by NASA, Roscosmos, and other international partners through forced and painful trial and error. In short, the road to today’s cautious procedures has been paved with countless failures and close calls over decades of space activity. For Cargo Dragon, the process involves berthing, more passive and less complex than docking. Outside of a dozen or so meters, the processes begin quite similarly. Cargo Dragon (Dragon 1) will very slowly approach the station’s several-hundred-meter keep out zone, typically no faster than a few m/s (mph).

Then follows a back-and-forth process of stop and go, in which SpaceX commands Dragon forward, halts at set locations, verifies performance and station readiness with NASA, and repeat. Once within 10 or so meters of the ISS, Dragon will begin carefully stationkeeping, essentially a version of formation flying without a hint of aerodynamic forces. ISS astronauts will then command the Canadarm2 robotic arm toward a sort of target/handle combo located on the spacecraft. The arm follows similar stop-start procedures before finally grappling Dragon, at which point the astronauts in command are legally required (/s) to quip something along the lines of “We’ve caught ourselves a Dragon!”

From start to finish, the process takes about 1.5 hours under optimal conditions. Around 2.5 hours after that, Canadarm2 will physically berth Dragon with one of several ISS berthing ports. Soon after, station astronauts can open Dragon’s hatch, snag some fresh goodies, and begin the unpacking process. CRS-17’s ISS arrival operations will be covered live on NASA TV.

Tesla CEO Elon Musk teases autobiography following fallout with Isaacson

“I need to tell my story myself and highlight lessons that I learned along the way that would be useful to others.”

Tesla CEO Elon Musk teased the potential for an autobiography following his fallout with author Walter Isaacson, who wrote a book on the serial entrepreneur in the past.

Isaacson met with C-SPAN’s American’s Book Club on November 13, and went into detail as to why he disagreed with Musk’s place in politics, especially with how he handled Department of Government Efficiency (DOGE):

“It’s a shame because had he gone into government and focused on what he’s good at…He could have changed the government for good, but instead…he started, you know, let’s get rid of this part of USAID and firing people.”

It’s sort of a shame to see Isaacson cast stones in the direction of Musk, whom he spent a significant amount of time with, aiming to put forth an accurate and realistic depiction of perhaps the greatest entrepreneur in the modern era.

However, Musk did not come back at Isaacson. Instead, he highlighted the need for what could potentially be his autobiography, aiming to “highlight lessons that [he] learned along the way that would be useful to others.”

Musk’s time in government was met with harsh criticisms from many, but there was a lot of support for the work that he did during his time with DOGE as well. Eventually, Musk’s responsibilities with DOGE started to wind down, and he pledged to step back from government to focus on his companies.

A Musk-written biography would potentially be a great book for those who are interested in his story, but also those who plan to enter entrepreneurism, tech, or the sciences, as there truly could be some excellent lessons within.

However, Musk’s recently approved compensation package and the tranches that could pay him $1 trillion in shares will likely take up most of his time. Tesla also has a lofty goal of launching Robotaxi and expanding the ride-hailing service to other areas of the country in the coming months.

Tesla (NASDAQ:TSLA) has gained fresh institutional support, with Nomura Asset Management expanding its position in the automaker. 

Nomura boosted its Tesla holdings by 4.2%, adding 47,674 shares and bringing its total position to more than 1.17 million shares valued at roughly $373.6 million. The move makes Tesla Nomura’s 10th-largest holding at about 1% of its entire portfolio.

Institutional investors and TSLA

Nomura’s filing was released alongside several other fund updates. Brighton Jones LLC boosted its holdings by 11.8%, as noted in a MarketBeat report, and Revolve Wealth Partners lifted its TSLA position by 21.2%. Bison Wealth increased its Tesla stake by 52.2%, AMG National Trust Bank increased its position in shares of Tesla by 11.8%, and FAS Wealth Partners increased its TSLA holdings by 22.1%. About 66% of all outstanding Tesla shares are now owned by institutional investors.

The buying comes shortly after Tesla reported better-than-expected quarterly earnings, posting $0.50 per share compared with the $0.48 consensus. Revenue reached $28.10 billion, topping Wall Street’s $24.98 billion estimate. Despite the earnings beat, Tesla continues to trade at a steep premium relative to peers, with a market cap hovering around $1.34 trillion and a price-to-earnings ratio near 270.

Recent insider sales

Some Tesla insiders have sold stock as of late. CFO Vaibhav Taneja sold 2,606 shares in early September for just over $918,000, reducing his personal stake by about 21%. Director James R. Murdoch executed a far larger sale, offloading 120,000 shares for roughly $42 million and trimming his holdings by nearly 15%. Over the past three months, Tesla insiders have collectively sold 202,606 shares valued at approximately $75.6 million, as per SEC disclosures.

Tesla rolls out fresh Supercharger pricing strategy to more locations

Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.

Tesla has rolled out a fresh Supercharger pricing strategy to more locations, as it confirmed it has added 550 additional sites in the United States to its “Live Pricing” strategy.

Live Pricing for Superchargers launched back in May, and was the company’s latest strategy to keep charging your EV cheap, affordable, and easy to understand.

Tesla has adjusted its pricing strategy at Superchargers several times over the past few years, with the most notable being the 2020 introduction of off-peak and on-peak Supercharging rates.

Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.

Tesla explained the program when it launched:

“We are piloting on-peak and off-peak pricing based on live Supercharger utilization rather than estimations. The average price remains unchanged, but this live feedback loop improves accuracy. This corrects off-peak pricing during times of congestion, or on-peak pricing when Superchargers are plentiful. You’ll always see the price before your session begins, and prices do not change mid-session. A small-scale pilot is launching at 10 sites and will expand based on feedback and success.”

The initial rollout only included Superchargers in California, but it was not all of them, only a handful instead. Tesla was attempting to launch it in a very controlled manner by using a Pilot Program that would iron out all the early bugs and potential issues it might run into.

However, the company expanded the program by launching it at an additional 550 sites in California, New Jersey, New York, Florida, and Illinois:

The price you pay is locked in when you plug in, so if the Supercharger station you are charging at becomes more crowded and the program bumps up the rates because of high utilization rates, you will still receive the cheaper price that was enabled when you arrived.
