Bacteria could be useful construction tools when it comes to building cities on Mars.

Elon Musk recently detailed his plans for establishing a city on Mars. But before we take up residence on the red planet, we’re going to need some help laying the groundwork. Here’s where bacteria come in.

A special group of microorganisms, called Shewanella oneidensis, would make excellent helpers, says Benjamin Lehner, a doctoral candidate at Delft University of Technology in the Netherlands.

Shewanella belongs to a group of bacterium called exoelectrogens, which possess an unusual skill: They can produce electricity. But that’s not all. Lehner says the bacterium can also mine iron out of the Martian soil.

In 2018, NASA sent a batch of these helpful bacterium to the space station to see how well they thrive in space. Now Lehner wants to send them on to Mars, ahead of human explorers.

“In its natural form, we can’t use much of the iron in the Martian soil,” Lehner said in a statement. “But S. oneidensis has the ability to turn part of the soil into magnetite, a magnetic oxide of iron.”

That iron would then be used as building materials for future structures on Mars.

So how would it work? Lehner says that three things should sent to Mars ahead of any human expeditions: a rover, a bioreactor and a 3D printer. The rover would fetch batches of Martian soil, called regolith, then feed it into the bioreactor.

The Martian soil is rich in iron and the S. oneidensis loves to munch on iron, so it would be waiting in the bioreactor, ready to chow down.

The bacteria would then produce magnetite as a byproduct from the regolith. The magnetite would then be extracted and separated from the rest of the soil with magnets. Finally, the 3D printer would turn this raw metal material into a host of valuable parts for humans.

The printer could create any part necessary—screws, nuts, bolts—for building structures (including human habitats) on Mars.

So how much iron could these microbes realistically produce? Leher and his team estimate they could have a substantial amount in a few year’s time.

According to the researchers, a 370-gallon (1,400-liter) reactor could yield about 770-lbs. (350 kilograms) of the material each year. “After 3.3 years, it would produce more iron than can fit inside the capsule,” he explained. “By sending several of these unmanned modules to Mars, we can produce a good amount of iron in a few years’ time.”

Bacteria are advantageous because they’re self-replicating, can withstand the harsh radiation on Mars, and are cheap to transport. They only need one thing: food.

To that end, Lehner suggests sending microalgae along with the bacteria. These organisms live off of sunlight and CO2, two things that are plentiful on Mars. The microalgae will turn those ingredients into nutrients and oxygen, perfect for the bacteria.

But what if some rogue bacteria make their way out of the reactor? Would we then contaminate Mars with Earth microbes? What does this mean for the search for life?

“We want to prevent our bacteria from contaminating the planet, since that could hinder the search for life on Mars,” Lehner said. To mitigate any chances of contamination, Lehner’s team says that the bioreactor and any iron material produced needs to be safely contained.

Cybertruck

Tesla Cybertruck fleet takes over at SpaceX’s Starbase

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.

The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.

However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.

It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.

A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.

The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.

However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.

It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.

SpaceX is opening up its internet service, Starlink, to those impacted by Hurricane Melissa, as it made landfall in Jamaica and the Bahamas as a Category 5 storm.

Hurricane Melissa is expected to reach wind speeds of over 165 MPH over the next few days as it extends out into the Atlantic Ocean by Thursday and Friday.

Citizens in Jamaica and the Bahamas have been preparing for the storm for the past week, getting necessary goods together and preparing for the massive storm to arrive. It finally did yesterday, and the first images and video of the storm are showing that it could destroy many parts of both countries.

Starlink is now being opened up for free until the end of November for those impacted by the storm in Jamaica and the Bahamas, SpaceX announced today:

It is a move similar to the one the company made last year as Hurricane Helene made its way through the United States, destroying homes and property across the East Coast. SpaceX offered free service for those impacted by the destruction caused by the storm.

The free Starlink service was available until the end of 2024.

Elon Musk’s companies have also made similar moves to help out those who are impacted by natural disasters. Tesla has offered Free Supercharging in the past, most notably during the California wildfires.

One major advantage of Starlink is that it is available for use in situations like this one, where power might be required to operate things like a modem and router.

Internet access is a crucial part of survival in these situations, especially as it can be the last leg some stand on to get in touch with emergency services or loved ones.

SpaceX has reached an incredible milestone with its Starlink program, officially surpassing 10,000 satellites launched into low Earth orbit since starting the program back in 2019.

Last Sunday, October 19, SpaceX launched its 131st and 132nd Falcon 9 missions of 2025, one from Cape Canaveral, Florida, and the other from Vandenberg, California.

The 10,000th Starlink satellite was aboard the launch from California, which was Starlink 11-19, and held 28 v2 mini optimized satellites.

The achievement was marked by a satellite tracker developed by Jonathan McDowell.

The first Starlink launch was all the way back on May 23, 2019, as SpaceX launched its first 60 satellites from Cape Canaveral using a Falcon 9 rocket.

Of the over 10,000 satellites in orbit, the tracker says 8,608 are operational, as some are intentionally de-orbited after becoming faulty and destroyed in the atmosphere.

SpaceX has truly done some really incredible things during its development of the Starlink program, including launch coverage in a global setting, bringing along millions of active subscribers that use the service for personal and business use, locking up commercial partnerships, and more.

Starlink currently operates in around 150 countries, territories, and markets and is available at least somewhere on all seven continents.

Additionally, Starlink has over 5 million subscribers worldwide, and 2.7 million have joined the program over the past year. It has revolutionized internet access on commercial aircraft as well, as several high-profile airlines like Qatar and United, among many others, have already installed Starlink on some of their planes to deliver more stable connectivity for passengers and crew.

SpaceX has the approval to launch 12,000 Starlink satellites from the FAA, but it plans to bring over 30,000 to its constellation, giving anyone the ability to have access to high-speed internet.
