NASA’s Parker Solar Probe takes first picture inside the Sun’s atmosphere

Traveling at the record-breaking speed of 213,200 miles per hour, NASA’s Parker Solar Probe came within 15 million miles of the Sun’s surface, completing its first solar encounter phase and rewarding scientists with the first picture ever taken from within our star’s atmosphere.

Launched on August 12, 2018 in a United Launch Alliance Delta IV Heavy rocket from Cape Canaveral, Florida, the probe will help provide answers to some of the mysteries of our Sun. In particular: Why is the atmosphere hotter than the surface? Why is the solar wind continuously accelerated? These are important questions considering the Sun is both essential for life and a potential danger through its magnetized materials’ interference with our satellites, electronics, and astronauts in orbit. Scientists on the craft’s team presented the initial set of new data from its encounter on December 12th during the 2018 American Geophysical Union meeting.

The Parker Probe’s team began downloading data from its journey on December 7th this year, but the actual Sun passage took place about a month earlier, from October 31st through November 11th. The delay was caused by the nature of the Sun itself – as a wide band radio source, communications are not possible anytime a craft is in front, behind, or to the side of it.

During the probe’s approaches, scientists rely on one of four beacons installed that signal the craft’s status. Mission controllers at the John Hopkins University Applied Physics Labs (JHUAPL) received the “A” beacon at 4:46 pm EST on November 7, 2018, indicating that the probe was operating well and collecting data. Also, more data from the probe’s initial encounter will be forthcoming next year following its next approach.

This latest visitor to the Sun was named after physicist Eugene Newman Parker, best known for his mid-1950s theories about solar wind and the Sun’s atmosphere being hotter than the surface itself, and the craft will likely be one more data point complimenting his predictions. Since the Parker Probe’s mission will encounter our star in ways never done before, its science team is not quite sure of what to expect.

“Parker is an exploration mission — the potential for new discoveries is huge,” Nour Raouafi, a Parker Solar Probe project scientist at the JHUAPL in Laurel, Maryland, was quoted on the issue. The craft will also pass by Venus a total of seven times and will come within 3.8 million miles of the Sun at its closest of 24 planned approaches.

Figuring out what the actual underlying physics of the Sun are is a challenge for scientists studying its activity. When observing the surface changes, the variations seen are difficult to classify as being caused by either the star’s activity or its rotation due to how fast it moves. The speed of the Parker Probe will allow it to nearly match the Sun’s rotational speed, one revolution per 27 days as viewed from Earth, meaning it will hover over one area for a short amount of time.

While there, it will be able to specifically collect data about activity caused by the Sun itself, thereby enabling scientists to revise their models accordingly. To collect data surrounding these questions, the probe was given a thermal heat shield that can withstand the 2,500 degrees Fahrenheit temperatures it will be exposed to while maintaining a mid-80s F temperature for its instruments.

In addition to the Parker Probe’s historic photo and data, NASA has been on a roll with milestones and discoveries this year. Launched in 1977, the Voyager 2 spacecraft became the second human-made object to enter interstellar space as it left our solar system on November 5th. The first was Voyager 1 when it left on August 25, 2012. NASA also landed its InSight craft on the surface of Mars on November 26, 2018, and several photos have been returned from it since, including a lander “selfie“. That mission had a second milestone with it via two CubeSats named Mars Cube One (MarCO), successfully demonstrating the use of tiny satellites in deep space. The satellites were able to relay InSight’s landing event data to its team much quicker than would be been possible with other orbiting satellites, and they even sent back a picture of the red planet as they passed by and continued into their long orbit around the Sun.

Tesla is using vehicle microphones to improve build quality: here’s how

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.

Tesla crushes Wall Street expectations, beats delivery estimates by over 15 percent

Tesla (NASDAQ: TSLA) beat Wall Street expectations of 406,000 vehicles delivered in Q2 by reporting 480,126 deliveries for the three months ending in June.

Tesla reported it delivered 467,762  Model 3 and Model Y units, while 12,364 Model S, Model X, and Cybertrucks switched hands during the quarter. The Model S and Model X were officially sunset this past quarter and will no longer be part of the company’s Production & Delivery reports moving forward.

The quarter is a pleasant surprise and a good rebound from Q1, when Tesla slightly missed the Wall Street consensus of 365,645 cars by reporting 358,023 deliveries for the first three motnhs of the year.

Energy storage deployments also provided some strength in Tesla’s delivery report, hitting 13.5 GWh for Q2. This is a particular division of Tesla’s business that has been overwhelmingly robust over the past few years, truly being a strong point of the company’s overall model.

For the year, Tesla analysts still predict deliveries to trend in the 1.69 million unit region, a modest 3 to 5 percent increase from the 1.64 million cars the company delivered last year. Tesla will likely return to more sequential and noticeable year-over-year growth as the Cybercab project starts to ramp up considerably in the next few years.

Tesla has some other potential catalysts to spur vehicle deliveries, too. Not only is it expecting Cybercab to truly start making a change in the next few years, but other vehicles could be entering the company’s lineup.

The slightly longer Model Y L has been a highly speculated release candidate in the U.S. It has already done incredibly well in China, and U.S. buyers have been wanting slightly more interior space than the Model Y. Now that the Model X is gone, it is more needed than ever.

Q2 highlights a pretty stable automotive division within Tesla, and no true concerns arise from these figures, especially considering it managed to beat expectations convincingly.

Tesla CEO Elon Musk posted a photo of himself standing with the Optimus production team inside Tesla’s Fremont factory, arms crossed amid workers in hard hats and safety vests. The image captures a pivotal industrial shift: the same facility space once dedicated to building Tesla’s flagship Model S sedan and Model X SUV is now home to the company’s humanoid robot manufacturing line.

Tesla’s Fremont Factory, acquired in 2010 from the former NUMMI joint venture between Toyota and GM, has been the company’s original U.S. manufacturing hub since Model S production began in 2012.

The Model X followed soon thereafter. These premium vehicles offered lower annual volumes, recently around 30,000 combined, compared to the high-volume Model 3 and Model Y lines that continue around the site. Over their combined run, the S and X accounted for roughly 610,000 units.

In late January 2026, during Tesla’s Q4 2025 earnings call, Elon Musk announced the end of Model S and Model X production in Q2 2026. The final vehicles rolled off the line in early May. Rather than retooling for another vehicle, Tesla chose to convert the dedicated S/X assembly area into a dedicated Optimus Gen 3 production line.

Model 3 and Y manufacturing remains unaffected. Tesla’s official Fremont Factory page now lists Optimus alongside the 3 and Y as core products.

The conversion was executed with remarkable speed. After production stopped, crews dismantled the existing vehicle line and installed entirely new modular equipment—including lines sourced from Germany and dozens of sub-lines for actuators, batteries, and other components—in roughly four months.

Musk described the timeline as “insanely fast,” noting it would be unprecedented for any other manufacturer. Initial Optimus output is expected to ramp slowly due to the robot’s roughly 10,000 unique parts and the brand-new production processes involved. The Fremont line targets an eventual capacity of 1 million Optimus units per year.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go

Optimus Development Timeline

  • August 19, 2021: Optimus (then called Tesla Bot) formally announced at Tesla’s first AI Day. A concept video showed a person in a suit demonstrating the vision for a general-purpose humanoid capable of dangerous, repetitive, or boring tasks using the same AI architecture as Full Self-Driving.
  • 2022: Early prototypes displayed. At the second AI Day in September, semi-functional units demonstrated walking across a stage and basic arm movements
  • 2023: September videos showed improved capabilities, including sorting colored blocks, precise limb awareness, and holding a Yoda pose.
  • 2024-early 2025: Factory integration videos showed Optimus navigating workspaces and handling objects like battery cells.
  • January 2026: Gen 3 mass-production activities began at Fremont, with reports of over 1,000 Gen 3 units already operating inside the factory for real-world learning and AI training
  • April 2026: Musk confirms Optimus production on converted Fremont line would begin in late July or August 2026. The Gen 3 reveal, originally eyed for Q1, was pushed closer to production start. A second, much larger Optimus factory at Giga Texas is under construction, with volume production targeted for Summer 2027 and long-term capacity of 10 million units annually
  • July 1, 2026: Musk’s on-site visit and team photo confirm the Optimus line is operational and the transition is actively progressing

Tesla positions Optimus as potentially its largest project ever, leveraging vertical integration, AI expertise, and car-like manufacturing know-how to scale humanoid robots first for its own factories and later for broader industrial and consumer use.

The Fremont conversion serves as a critical proving ground for this ambitious new chapter in Tesla’s already-rich history.
