Elon Musk's space exploration company has filed preliminary paperwork to sell shares to the public, according to two sources familiar with the filing, a blockbuster offering that would likely rank as the biggest ever and could make its founder the world's first trillionaire.

A SpaceX IPO promises to be one of the biggest Wall Street events of the year, with several investment banks lining up to help raise tens of billions to fund Musk's ambitions to set up a base on the moon, put datacenters the size of several football fields in orbit and possibly one day send a man to Mars.

The sources spoke on condition of anonymity because they were not authorized to talk publicly about the confidential registration with the Securities and Exchange Commission.

SpaceX did not respond immediately to a request for comment.

Exactly how much SpaceX plans to raise has not been disclosed but the figure is reportedly as much as $75 billion. At that level, the offering would easily eclipse the $29 billion that Saudi Aramco raised in its IPO in 2019.

The offering, coming possibly in June, could value all the shares of SpaceX at $1.5 trillion, nearly double what the company was valued in December when some minority owners sold their stakes, according to research firm Pitchbook, before an acquisition that increased its size.

Musk owns 42% of the SpaceX now, according to Pitchbook, though that figure will change with the IPO when new owners are issued shares. In any case, he is likely to pierce the trillion dollar mark because he is already close. Forbes magazine estimates Musk's net worth at roughly $823 billion.

In addition to making reusable rockets to hurl astronauts and hardware into orbit, SpaceX owns Starlink, the world’s largest satellite communications company. The company also recently brought under its roof two other Musk businesses, social media platform X, formerly Twitter, and artificial intelligence business, xAI, in a controversial transaction because both the seller and the buyer were controlled by him.

SpaceX has become the biggest commercial launch company in its industry, responsible for sending payloads into orbit for customers across the globe, but has also benefited from big taxpayer spending. That has raised conflicts of interest issues given that Musk was the biggest donor to President Donald Trump's campaign and is still a big backer.

In the past five years, SpaceX won $6 billion in contracts from NASA, the Defense Department and other U.S. government agencies, according to USAspending.gov.

Among current SpaceX owners is Donald Trump Jr, the president's oldest son. He owns a shares through 1789 Capital. That venture capital firm made him a partner shortly after his father won the presidency for a second time and has been buying up federal contractors seeking to win taxpayer money ever since.

The White House and Trump himself have repeatedly denied there are any conflicts of interest between his role as president and his family's businesses.

Elon Musk vows to launch solar-powered data centers in space

To Outer Space

Elon Musk vowed this week to upend another industry just as he did with cars and rockets — and once again he's taking on long odds.

The world's richest man said he wants to put as many as a million satellites into orbit to form vast, solar-powered data centers in space — a move to allow expanded use of artificial intelligence and chatbots without triggering blackouts and sending utility bills soaring.

To finance that effort, Musk combined SpaceX with his AI business on Monday, February 2, and plans a big initial public offering of the combined company.

“Space-based AI is obviously the only way to scale,” Musk wrote on SpaceX’s website, adding about his solar ambitions, “It’s always sunny in space!”

But scientists and industry experts say even Musk — who outsmarted Detroit to turn Tesla into the world’s most valuable automaker — faces formidable technical, financial and environmental obstacles.

Feeling the heat

Capturing the sun’s energy from space to run chatbots and other AI tools would ease pressure on power grids and cut demand for sprawling computing warehouses that are consuming farms and forests and vast amounts of water to cool.

But space presents its own set of problems.

Data centers generate enormous heat. Space seems to offer a solution because it is cold. But it is also a vacuum, trapping heat inside objects in the same way that a Thermos keeps coffee hot using double walls with no air between them.

“An uncooled computer chip in space would overheat and melt much faster than one on Earth,” said Josep Jornet, a computer and electrical engineering professor at Northeastern University.

One fix is to build giant radiator panels that glow in infrared light to push the heat “out into the dark void,” says Jornet, noting that the technology has worked on a small scale, including on the International Space Station. But for Musk's data centers, he says, it would require an array of “massive, fragile structures that have never been built before.”

Floating debris

Then there is space junk.

A single malfunctioning satellite breaking down or losing orbit could trigger a cascade of collisions, potentially disrupting emergency communications, weather forecasting and other services.

Musk noted in a recent regulatory filing that he has had only one “low-velocity debris generating event" in seven years running Starlink, his satellite communications network. Starlink has operated about 10,000 satellites — but that's a fraction of the million or so he now plans to put in space.

“We could reach a tipping point where the chance of collision is going to be too great," said University at Buffalo's John Crassidis, a former NASA engineer. “And these objects are going fast -- 17,500 miles per hour. There could be very violent collisions."

No repair crews

Even without collisions, satellites fail, chips degrade, parts break.

Special GPU graphics chips used by AI companies, for instance, can become damaged and need to be replaced.

“On Earth, what you would do is send someone down to the data center," said Baiju Bhatt, CEO of Aetherflux, a space-based solar energy company. "You replace the server, you replace the GPU, you’d do some surgery on that thing and you’d slide it back in.”

But no such repair crew exists in orbit, and those GPUs in space could get damaged due to their exposure to high-energy particles from the sun.

Bhatt says one workaround is to overprovision the satellite with extra chips to replace the ones that fail. But that’s an expensive proposition given they are likely to cost tens of thousands of dollars each, and current Starlink satellites only have a lifespan of about five years.

Competition — and leverage

Musk is not alone trying to solve these problems.

A company in Redmond, Washington, called Starcloud, launched a satellite in November carrying a single Nvidia-made AI computer chip to test out how it would fare in space. Google is exploring orbital data centers in a venture it calls Project Suncatcher. And Jeff Bezos’ Blue Origin announced plans in January for a constellation of more than 5,000 satellites to start launching late next year, though its focus has been more on communications than AI.

Still, Musk has an edge: He's got rockets.

Starcloud had to use one of his Falcon rockets to put its chip in space last year. Aetherflux plans to send a set of chips it calls a Galactic Brain to space on a SpaceX rocket later this year. And Google may also need to turn to Musk to get its first two planned prototype satellites off the ground by early next year.

Pierre Lionnet, a research director at the trade association Eurospace, says Musk routinely charges rivals far more than he charges himself —- as much as $20,000 per kilo of payload versus $2,000 internally.

He said Musk’s announcements this week signal that he plans to use that advantage to win this new space race.

“When he says we are going to put these data centers in space, it’s a way of telling the others we will keep these low launch costs for myself,” said Lionnet. “It’s a kind of powerplay.”

Houston native picked for 2025 class of NASA astronaut candidates

space crew

NASA has selected 10 new astronaut candidates, including one whose hometown is Houston, for its 2025 training class. The candidates will undergo nearly two years of training before they can assume flight assignments.

The 10 future astronauts were introduced during a recent ceremony at NASA’s Johnson Space Center, whose facilities include an astronaut training center. NASA received more than 8,000 applications for the 10 slots.

“Representing America’s best and brightest, this astronaut candidate class will usher in the Golden Age of innovation and exploration as we push toward the moon and Mars,” said Vanessa Wyche, director of NASA Johnson.

NASA’s 24th astronaut class reported for duty in mid-September at Johnson Space Center. Their training will prepare them for missions to the International Space Station and the moon, among other activities. Graduates will become members of NASA’s astronaut corps.

Among the recently selected candidates is Anna Menon, who was born in Houston and considers it her hometown. She’s married to NASA astronaut Dr. Anil Menon, a flight surgeon who completed his training in 2022.

Most recently, Anna Menon was a senior engineer at Elon Musk’s SpaceX, where she spent seven years managing crew operations for the Dragon and Starship spacecraft. Previously, Menon worked at NASA’s Mission Control Center in Houston, where she supported medical software and hardware aboard the International Space Station.

In 2024, Menon flew into space as a mission specialist and medical officer aboard SpaceX’s Polaris Dawn private spacecraft. A highlight of the low-orbit trip was the first commercial spacewalk.

Texas native Rebecca Lawler, a native of the Dallas-Fort Worth suburb of Little Elm, is one of Menon’s nine classmates.

Lawler, a former lieutenant commander in the Navy, was a Navy P-3 pilot and experimental test pilot who logged over 2,800 flight hours aboard more than 45 aircraft. At the time she was chosen to be an astronaut candidate, Lawler was a test pilot for United Airlines.

The eight other astronaut candidates in the 2025 class are:

  • Ben Bailey, who was born and raised in Charlottesville, Virginia
  • Lauren Edgar, whose hometown is Sammamish, Washington
  • Adam Fuhrmann, who’s from Leesburg, Virginia
  • Cameron Jones, a native of Savanna, Illinois
  • Yuri Kubo, a native of Columbus, Indiana
  • Imelda Muller, whose hometown is Copake Falls, New York
  • Erin Overcash, who’s from Goshen, Kentucky
  • Katherine Spies, a native of San Diego

International Space Station welcomes astronauts from successful Axiom Mission 4

Out In Space

The first astronauts in more than 40 years from India, Poland and Hungary arrived at the International Space Station on Thursday, ferried there by SpaceX on a private flight.

The crew of four will spend two weeks at the orbiting lab, performing dozens of experiments. They launched Wednesday from NASA’s Kennedy Space Center.

America’s most experienced astronaut, Peggy Whitson, is the commander of the visiting crew. She works for Axiom Space, the Houston company that arranged the chartered flight.

Besides Whitson, the crew includes India’s Shubhanshu Shukla, a pilot in the Indian Air Force; Hungary’s Tibor Kapu, a mechanical engineer; and Poland’s Slawosz Uznanski-Wisniewski, a radiation expert and one of the European Space Agency’s project astronauts on temporary flight duty.

No one has ever visited the International Space Station from those countries before. The time anyone rocketed into orbit from those countries was in the late 1970s and 1980s, traveling with the Soviets.

“It’s an honor to have you join our outpost of international cooperation and exploration," NASA's Mission Control radioed from Houston minutes after the linkup high above the North Atlantic.

The new arrivals shared hugs and handshakes with the space station's seven full-time residents, celebrating with drink pouches sipped through straws. Six nations were represented: four from the U.S., three from Russia and one each from Japan, India, Poland and Hungary.

"It’s so great to be here finally. It was a long quarantine," Whitson said, referring to the crew's extra-long isolation before liftoff to stay healthy.

They went into quarantine on May 25, stuck in it as their launch kept getting delayed. The latest postponement was for space station leak monitoring, NASA wanted to make sure everything was safe following repairs to a longtime leak on the Russian side of the outpost.

It's the fourth Axiom-sponsored flight to the space station since 2022. The company is one of several that are developing their own space stations due to launch in the coming years. NASA plans to abandon the International Space Station in 2030 after more than three decades of operation, and is encouraging private ventures to replace it.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
