Mars’ invisible auroras come to life in new NASA animation
The sky on Mars has a wind of ultraviolet light that pulses as it moves across the red planet. This phenomenon is similar to Earth’s aurora borealis events, lasting from sunset until midnight, and NASA has created a new animation using data obtained from an instrument on the MAVEN spacecraft to demonstrate what it might look like to future astronauts in orbit. That is, it’s what they would see if it wasn’t invisible to the naked human eye.
“The ultraviolet glow comes mostly from an altitude of about 70 kilometers (approximately 40 miles), with the brightest spot about a thousand kilometers (approximately 600 miles) across, and is as bright in the ultraviolet as Earth’s northern lights,” explained Zac Milby, a researcher at the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP).
Milby is one of several other LASP scientists that published a recent study on the ‘nightglow’ data in the journal JGR Space Physics. The team analyzed two Martian years’ worth of images taken by the Imaging Ultraviolet Spectrograph (IUVS) on the Mars Atmosphere and Volatile Evolution (MAVEN) mission spacecraft to find the reported wind and UV emission behavior. “The MAVEN spacecraft orbiting Mars has obtained a new type of imaging data which reveals the effects of global‐scale winds and waves in the upper atmosphere,” the study’s Plain Language Summary details.
With a mission to Mars in the near-term travel plans for both NASA and SpaceX, learning as much as possible about the planet’s atmosphere is essential. Preparations for both on-site scientific study and astronaut safety will need to incorporate the Martian ground conditions, so studies like this one provide very important and relevant data. The recent findings also demonstrate the importance of cooperative international efforts in exploring deep space, namely because MAVEN wasn’t the first spacecraft to demonstrate the existence of the ‘nightglow’ phenomenon. Rather, the European Space Agency’s Mars Express orbiter mission revealed it in 2003, leading the path for follow up and further study.
It may also be interesting to note that although Mars-based astronauts may not be able to see the UV aurora-type nightglow with their normal eyesight, instruments could likely come into play to overcome such limitations. We already have commercially available UV cameras on Earth, for instance. There’s even a UV camera smartphone add-on that one could see being used on Mars to watch the glow show in a similar fashion to augmented reality starfinders on the market.
Of course, much more science-oriented UV cameras would likely accompany any travelers to the planet, but it’s fun to imagine what may be available to more tourist-types or even Martian colonists some day.

Tesla readies its autonomous Cybercab and Robotaxi cleaning service
A Texas permit just confirmed Tesla’s cleaning robot is coming to service its Cybercab and Robotaxi fleet.
A routine Texas building permit may have quietly confirmed that Tesla’s robot vacuum and autonomous cleaning bot for the Robotaxi and Cybercab is coming. A state filing with the Texas Department of Licensing and Regulation, as first discovered by Tesla enthusiast Spencer and posted to X, that project number TABS2025022006, lists the scope of work at Tesla’s Austin Robotaxi hub at 5900 E Ben White Blvd to include a “Cleaning Robot” alongside Supercharger cabinets and an Equipment Inspection System.
Tesla first showed the cleaning robot publicly on January 31, 2025, posting a short video on X with the caption “This robot sucks,” showing a large robotic arm inside a Cybercab cabin switching between attachments to vacuum debris, pick up trash, and wipe down surfaces.
The operational case for this hardware comes down to mathematics. A robotaxi running rides across Austin needs to cycle passengers continuously to generate revenue. Every minute a vehicle sits waiting for a human cleaning crew is a minute it is not earning. A robotic arm that can fully clean a Cybercab cabin between rides in under two minutes removes one of the key bottlenecks in fleet utilization that no autonomous vehicle company has yet solved at scale.

The 5900 E Ben White Blvd address sits roughly 12 miles southwest of Gigafactory Texas, where Tesla has been mass producing its Cybercab. The Ben White facility is expected to functions as Tesla’s Austin Robotaxi Hub, the physical base of operations where fleet vehicles return between rides to charge, get cleaned, and undergo inspection before being dispatched again – and all autonomously. One can imagine a Cybercab dropping off a passenger, routes itself back to Ben White, pulls into the cleaning station, charges on one of the Supercharger cabinets listed in the same permit, passes the equipment inspection system, and returns to service, all without a human making a single decision.
The sighting activity around both locations has accelerated in parallel with production. By mid-March 2026, Cybercabs were spotted regularly on public roads across Austin and Silicon Valley. Tesla’s Robotaxi operations in Texas has expanded to cover the entire Austin metro area and has spread to Dallas, while autonomous Cybercab employee shuttle runs at Gigafactory Texas are also set to begin soon. What it represents is the physical infrastructure behind a fleet that Tesla intends to run without anyone cleaning, driving, or dispatching it by hand.
SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.
This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.
A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.
Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.
These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.
The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.
With each flight, Starship edges closer to full reusability and operational maturity. Success on July 16 would mark another step toward routine access to space and the ambitious vision of humanity becoming a spacefaring civilization.
Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
