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 necessaryscrews, 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.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).

SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.

NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.

“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.

“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.

SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.

“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.

The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.

The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.

Starlink India’s launch cleared a key regulatory hurdle after securing a long-awaited license from the country’s telecom ministry. Starlink’s license approval in India paves the way for commercial operations to begin, marking a significant milestone after a three-year wait.

The Department of Telecommunications granted Starlink a Global Mobile Personal Communication by Satellite (GMPCS) license, enabling it to roll out its high-speed internet service. Local reports hinted that Starlink plans to launch its services within the next two months. Starlink India’s services are expected to be priced at ₹3,000 per month for unlimited data. Starlink service would require a ₹33,000 hardware kit, including a dish and router.

“Starlink is finally ready to enter the Indian market,” sources familiar with the rollout plans confirmed, noting a one-month free trial for new users.

Starlink has forged distribution partnerships with Indian telecom giants Reliance Jio and Bharti Airtel to streamline deployment and retail logistics. However, the company still awaits spectrum allocation and final clearances from India’s space regulator, IN-SPACe, and national security agencies before its full launch, expected before August 2025.

India’s satellite internet market is becoming increasingly competitive, with Starlink joining rivals like OneWeb and Jio Satellite Communications. While Starlink positions itself as a premium offering, its entry has sparked debate among domestic telecom operators over spectrum pricing.

Local reports noted that other players in the industry have raised concerns over the lower regulatory fees proposed for satellite firms compared to terrestrial operators, highlighting tensions in the sector.

Starlink India’s launch represents a transformative step toward expanding internet access in one of the world’s largest markets. Starlink could redefine connectivity for millions in underserved regions by leveraging its advanced satellite technology and strategic partnerships. As the company navigates remaining regulatory steps, its timely rollout could set a new standard for satellite internet in India, intensifying competition and driving innovation in the telecom landscape.

SpaceX to decommission Dragon spacecraft in response to Pres. Trump war of words with Elon Musk

Elon Musk says SpaceX will decommission Dragon as a result of President Trump’s threat to end his subsidies and government contracts.

SpaceX will decommission its Dragon spacecraft in response to the intense war of words that President Trump and CEO Elon Musk have entered on various social media platforms today.

President Trump and Musk, who was once considered a right-hand man to Trump, have entered a vicious war of words on Thursday. The issues stem from Musk’s disagreement with the “Big Beautiful Bill,” which will increase the U.S. federal deficit, the Tesla and SpaceX frontman says.

How Tesla could benefit from the ‘Big Beautiful Bill’ that axes EV subsidies

The insults and threats have been brutal, as Trump has said he doesn’t know if he’ll respect Musk again, and Musk has even stated that the President would not have won the election in November if it were not for him.

President Trump then said later in the day that:

“The easiest way to save money in our Budget, Billions and Billions of Dollars, is to terminate Elon’s Government Subsidies and Contracts. I was always surprised that Biden didn’t do it!”

Musk’s response was simple: he will decommission the SpaceX capsule responsible for transporting crew and cargo to the International Space Station (ISS): Dragon.

Dragon has completed 51 missions, 46 of which have been to the ISS. It is capable of carrying up to 7 passengers to and from Earth’s orbit. It is the only spacecraft that is capable of returning vast amounts of cargo to Earth. It is also the first private spacecraft to take humans to the ISS.

The most notable mission Dragon completed is one of its most recent, as SpaceX brought NASA astronauts Butch Wilmore and Suni Williams back to Earth after being stranded at the ISS by a Boeing Starliner capsule.

SpaceX’s reluctance to participate in federally funded projects may put the government in a strange position. It will look to bring Boeing back in to take a majority of these projects, but there might be some reluctance based on the Starliner mishap with Wilmore and Williams.
