NASA’s InSight hopes to detect “marsquakes”, deploys seismometer on Mars
In another historic feat for NASA’s InSight lander, a seismometer has now been deployed on Mars, marking the first time a scientific instrument has been placed onto the surface of another planet. Once the craft’s team have things set up for readings, its instruments will begin measuring the internal vibrations of the red planet, hoping to ultimately learn about the activities and composition of its core and crust. InSight’s instruments will also study how powerful and frequent seismic activity is on Mars along with how often the surface is hit with meteorites. If we’re hoping to explore and possibly live there one day, this is all very important information to have.
After launching on May 5, 2018, aboard an Atlas rocket in California, InSight and its MarCO twin CubeSat companions traveled through deep space for around 6 months before landing on the Martian surface at 11:52 PST on November 26, 2018, an event watched live around the world, including a broadcast in Times Square, New York City. The planned mission for the craft is a little over 1 Martian year, i.e., about 2 Earth years, during which time it will aim to provide scientific data useful for understanding the processes that have shaped the rocky planets of our solar system. In other words, the things InSight learns about Mars will be directly relevant to our own planet as well.
InSight’s name is actually an acronym for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport”, each part being a reference to the specific science it will be conducting. There are several auxiliary instruments on board the lander that will assist or complement its main mission. However, there are 3 scientific instruments on the craft to help meet its objectives.
First, a seismometer named the Seismic Experiment for Interior Structure (SEIS) will study seismic waves from the Martian surface to study the planet’s crust. When magma moves or meteorites hit, the instrument will detect the motion and gather information that will tell scientists about Mars’ temperature, pressure, and composition. This is the instrument featured in the lander’s recent photo.
Second, a heat flow probe named the Heat Flow and Physical Properties Probe (HP3) will burrow more than 10 feet into the surface to measure the heat still flowing out of Mars, giving clues about how it evolved and whether Earth and Mars are made of the same materials. Finally, a radio science instrument named the Rotation and Interior Structure Experiment (RISE) will measure tiny changes in the location of InSight to measure Mars’ “wobbles” on its axis. This movement data will provide information about the planet’s core.
InSight is conducting its experiments on the western side of the Elysium Planitia of Mars, a smooth, flat region near the planet’s equator. The location was chosen from a pool of 22 candidate landing sites, all within Elysium, evaluated during several workshops from 2013-2015. The decision was made based on Elysium’s proximity to the equator (maximum sun for InSight’s solar arrays), low elevation (plenty of atmospheric space for its landing), lack of rocks and slopes (flat enough for the instruments to deploy and work properly), and the subsurface structure (so the digging instruments could burrow easily).
Next, InSight will finish setting up its remaining instruments and begin its full science mission. We can expect to continue receiving image updates from the lander as more milestones are reached. Here’s an extra bonus if you want to feel like you’re “there” with InSight: NASA’s “Experience InSight” interactive web page lets you control a virtual version of the lander in a Martian environment. You can deploy its solar panels, move around a few of its instruments, or just learn about the various parts that make up the mission. There are additionally two virtual cameras, just like the ones onboard the actual craft, enabling you to watch the movements you’re making, just like InSight’s team sees from their control center.

It appears that there are several big changes to this next-generation version of Optimus, some of which have been discussed by Musk and Tesla in the past.
The first is purely cosmetic, but the gold color that Optimus is wearing in this is a new and fresh look that we have not seen before.
Perhaps the most interesting change that is evident here is the hands, which are much more detailed than past versions of Optimus:
However, we’re not too sure that these are what will be released with the next-gen Optimus, because they don’t appear to be functional, and they are more reminiscent of mannequin hands than anything.
The hands on Optimus have been a significant part of the program, as they are among the most crucial pieces of equipment on a robot. It needs to be able to perform both delicate and more imposing tasks. Tesla has aimed for Optimus to be able to thread needles or play the piano.
It was one of the most discussed improvements the company mentioned in past comments regarding how it planned to improve from Gen 2 to this next version.
Musk mentioned regarding Optimus:
“Next-generation Optimus hand, which we have in prototype form, has actuators that have moved to the forearm, just like humans, and they operate the fingers through cables, just like human hands.”
Within Optimus lies a significant opportunity for Tesla to gain considerable strength in terms of market share and valuation.
If Tesla can efficiently develop and deploy the humanoid robot over the next several years, the company stands to gain, as companies will utilize it for tasks that require tedious labor.
Musk recently said Optimus will be a major contributor to Tesla’s valuation moving forward. He believes it will make up roughly 80 percent of the company’s value.

Tesla CEO Elon Musk to provide more details for Master Plan Part IV
Musk stated that he would be adding specifics to the plan in a later update.
Tesla CEO Elon Musk will be adding more specifics to the recently-released Master Plan Part IV. Musk shared the update on social media platform X amidst conversations about the general nature of the Master Plan Part IV.
In a conversation on X, Musk responded to a post from Tesla retail shareholder and bull Dave Lee, who observed that the currently released Master Plan Part IV could really just be the introduction to the real plan due to its absence of specifics.
Elon Musk responded, stating that he would be adding specifics to the plan in a later update. “Fair enough. Will add more specifics,” Musk wrote in his post.
Tesla has been following Elon Musk’s Master Plans for decades. The first Master Plan, released in 2006, outlined the company’s path from the original Tesla Roadster to the Model 3, as well as the first steps for Tesla Energy. Master Plan Part Deux, released in 2016, covered the ramp of Tesla Energy, the expansion of Tesla’s vehicle lineup, and the rollout of a Robotaxi service.
Master Plan Part 3 was more ambitious as it was generally an in-depth proposal for achieving a global sustainable entry economy by transitioning to electricity-powered vehicles, homes, and industry, which will, in turn, be powered by renewable energy sources like solar and wind. Master Plan Part 3 also included a five-step plan to accomplish this, allowing the world to transition to a fully electrified future.
Master Plan Part IV, which was released a few days ago, focused on automation and artificial intelligence to achieve sustainable abundance. But while the first two Master Plans were very clear and specific and Master Plan Part 3 was very in-depth, Master Plan Part IV was quite general and vague in comparison. It was easy to tell that Optimus would play a big role in the pursuit of sustainable abundance, but apart from that, there were no specifics as to how Tesla intended to achieve its goals.
Fortunately, these specifics would be discussed by Musk in a later update to the plan.

Tesla just had its best wholesale month this year in China
Tesla China’s wholesale figures include both vehicles that are sold domestically and exported abroad.
Tesla China just had its best wholesale month this 2025 so far. In August, the electric vehicle maker sold 83,192 vehicles wholesale, a 22.55% increase compared to July 2025’s 67,886 units.
Tesla China’s wholesale figures are still down year-over-year, but the company’s momentum seems notable, especially with the arrival of the Model Y L.
August 2025 figures
As noted in a CNEV Post report, August 2025’s 83,192 wholesale figures are 4.04% less than the 86,697 units that were sold in the same period last year. It is, however, a 22.55% improvement from the previous month. From January to August, Tesla China sold 515,552 units wholesale, a 12.24% year-over-year decrease.
It should be noted that Tesla China’s wholesale figures include both vehicles that are sold domestically and exported abroad. With this in mind, August’s results bode well for Tesla China, as it suggests that Gigafactory Shanghai is now hitting its pace with both its domestic deliveries and its exports. Giga Shanghai serves as Tesla’s primary vehicle export hub.
Model Y L factor
Tesla had a challenging first quarter this year, thanks in part to the changeover to the Model Y across the Fremont factory, Giga Texas, Giga Shanghai, and Giga Berlin-Brandenburg. This changeover resulted in low sales in the first quarter. Political controversies surrounding Elon Musk and violence against Tesla stores and vehicles in the first and second quarters in the United States and Europe did not help much either.
This Q3, however, Tesla seems to be hitting its stride, especially in China. The launch of the new Model Y L has allowed Tesla to compete in the six-seat, large SUV segment, a market that was previously closed to the standard Model Y. Reports have suggested that Tesla China has been seeing a lot of demand for the Model Y L, which should help the company achieve higher sales this quarter and the remaining months of the year.
