Tesla’s ‘Bioweapon Defense Mode’ is proving invaluable once more amid CA’s wildfires
Tesla Model S and Model X owners affected by the ongoing wildfires in CA are thanking the electric car maker once more for their vehicles’ Bioweapon Defense Mode, which allows passengers to breathe clean air inside the cabin despite hazardous air conditions outside.
The state of CA is currently experiencing several blazes. In Southern CA alone, authorities from the Riverside County Sheriff’s Department have confirmed that the Sandalwood Fire in Calimesa has taken the lives of two individuals, an 89-year-old woman in a mobile home and another person that is yet to be identified.
The Sandalwood Fire, which has so far burned 820 acres and was at least 25% contained as of Saturday, is only one of several blazes in the state. The Saddleridge Fire, currently the largest in the state, has burned more than 7,500 acres and destroyed around 31 homes. Amidst these blazes, the South Coast Air Quality Management District has urged residents to protect themselves from heavy smoke and dangerous air conditions.
It is these dangerous air conditions that are being addressed by Tesla’s Bioweapon Defense Mode for the Model S and X, and some electric car owners have taken to social media to share their experiences with the feature. A Tesla Model X owner who goes by the handle @BLKMDL3 on Twitter, for one, mentioned that Bioweapon Defense Mode was a “lifesaver” as he and his passengers were traveling in Los Angeles.
“Thank you Elon Musk and Tesla for helping us with breathing issues during the fires today in Los Angeles due to bad air quality. Bioweapon defense mode is a life saver,” the Tesla owner wrote.
Fellow Tesla enthusiast and r/TeslaMotors subreddit member u/cherrycolasoda shared a similar experience that was briefly captured on film. The Tesla enthusiast mentioned that Bioweapon Defense Mode significantly helped with the air quality in the cabin as they passed through an area that was practically surrounded by fires. The vehicle’s Autopilot system reportedly functioned normally, following lane lines without any difficulties despite the conditions on the road.
Bioweapon Defense Mode is made possible by the extremely large HEPA filter in the Model X (later equipped on the Model S as well). Tesla notes that Bioweapon Defense Mode is “100 times more effective than premium automotive filters, removing at least 99.97% of fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen, and mold spores.”
These statements were met with a notable degree of skepticism and dismissal from critics, though Tesla later demonstrated Bioweapon Defense Mode’s capabilities by holding a test on a Model X. During the demonstration, the company placed the all-electric SUV inside a bubble contaminated with extreme levels of pollution (1,000 µg/m3 of PM2.5 vs. the EPA’s “good” air quality index limit of 12 µg/m3). Bioweapon Defense Mode effectively scrubbed the air inside the Model X’s cabin in 2 minutes, and over the next few minutes, the vehicle started cleaning the air around the SUV as well.

SpaceX scores another massive Pentagon deal to support military satellites
SpaceX just picked up another $1.6 billion from the Pentagon, with the U.S. Space Force awarding two task orders worth $1.6 billion to fly 18 Falcon 9 missions from Vandenberg Space Force Base in California through the end of 2027. The launches will carry satellites for the Space Based Sensing and Targeting portfolio, a set of programs meant to help the military detect and track airborne threats and relay that information across forces in near real time.
The award falls under National Security Space Launch Phase 3 Lane 1, the Space Force’s faster, commercial style procurement track for missions that do not require the military’s most demanding certification process. It is also the largest single order publicly disclosed under that program so far, and the first task order issued since the Space Force nearly tripled Lane 1’s contract ceiling from $5.6 billion to $17 billion on July 17.
SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
Eric Zarybnisky, the Space Force’s acting portfolio acquisition executive for space access, said the entire process, from identifying the requirement to signing the contract, took about two months, including a month set aside for companies to prepare proposals.
SpaceX is not just launching these satellites. It already holds the contracts to build two of the programs within the same portfolio, $4.16 billion for the Space Based Airborne Moving Target Indicator system and $2.29 billion for the Space Data Network Backbone, which Teslarati covered in May. That means SpaceX is now responsible for both building key pieces of the military’s next generation sensing network and getting them into orbit.
With this latest award, SpaceX’s Pentagon contract total for 2026 alone tops $8 billion, adding to a defense portfolio that already includes the Golden Dome missile defense software group SpaceX joined in April and a string of GPS launches it inherited after ULA’s Vulcan rocket ran into a booster anomaly, which we detailed in March.
Lane 1’s vendor pool technically includes seven companies: SpaceX, ULA, Blue Origin, Rocket Lab, Stoke Space, Impulse Space, and Relativity Space. In practice, SpaceX remains the only provider with the combination of launch cadence, flight proven Falcon 9 hardware, and West Coast infrastructure to support a campaign requiring roughly one Vandenberg launch a month for the next year and a half.
Some lawmakers have flagged the growing concentration of national security launches with one company as a risk worth watching. For now, the Space Force keeps backing SpaceX, with it being the company that shows up ready to launch.

Elon Musk sheds two new bits of detail on Starship after 13th test launch
Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.
SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.
The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.
SpaceX Starship just nailed something it’s never done before
Nevertheless, more details are coming out about Starship, and Musk is doing the talking.
Starship Will Be Retrieved in the Ocean
Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

— Elon Musk (@elonmusk) July 28, 2026
This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.
Ship Could Have Been Caught by Tower Arms, Musk claims
Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.
The ship landing was precise, meaning that it would have been caught by the tower arms https://t.co/6nbNrRfX9P

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.
It is a necessity to make life multiplanetary.

Elon Musk updates the SpaceX timeline for Mars
Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.
The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.
Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

Mars lander a few years sooner.
— Elon Musk (@elonmusk) July 29, 2026
The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”
Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.
Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.
In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.
The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.
