Elon Musk says that SpaceX’s newest Starship prototype just passed its first test, clearing the way for the rocket to perform a form of testing that has destroyed all previously full-scale prototypes.

Known as a cryogenic proof test and reportedly scheduled to kick off as early as tonight (April 26th), SpaceX will fill some or all of the Starship SN4 prototype with ultra-cold liquid nitrogen. Used to simulate the similarly cold properties of Starship’s liquid oxygen and methane, liquid nitrogen (LN2) is chemically neutral and wont catch fire or explode in the event of a leak or total vehicle failure. SpaceX has performed many of those tests over the last six or so months, none of which were completed successfully with full-scale rocket tanks.

A series of test tanks (the same width as Starship but much shorter) did manage some impressive successes and proved that SpaceX’s current methods can technically build a rocket that’s up to the standards of spaceflight. Still, SpaceX needs to demonstrate that that remains true when multiple tanks and other components are attached to form a complete rocket. Enter Starship SN4’s April 25th and proposed April 26th tests.

Elon Musk says that Starship SN4 successfully finished an “ambient pressure test” early on April 26th, most likely referring to a test where the rocket’s tanks were filled with ambient temperature nitrogen gas. SpaceX technicians were eventually seen on mobile lifts spraying Starship with what appeared to be water (soapy water is a surprisingly simple way to find leaks in a pressure vessel – simply spray and look for bubbles).

It’s unclear if SpaceX actually pressurized the ship to the levels it has for past dedicated pressure tests, where verifying that the tank doesn’t burst is the main goal. If Starship SN4 did reach nominal flight pressures (6-8+ bar, 90-120 psi), it certainly bodes well for the test that’s to come.

Musk says that the next steps for Starship SN4 could begin – in the form of a cryogenic proof test – as early as April 26th, likely also in the late evening to early morning. During the ambient air test, Starship had some visible condensation on the exterior of its steel skin. The giveaway for the start of cryogenic testing will be the formation of frost on the rocket’s skin as the cold liquid nitrogen inside cools the steel to the point that it starts freezing water vapor out of the humid Texas air.

SpaceX has road closures optioned every day from April 26th to May 1st, leaving plenty of opportunities for a cryogenic proof test whenever Starship SN4 is deemed ready. If things go according to plan, Starship could be “physically” ready for a 150m (500 ft) hop test as early as a “few weeks” from now, though Musk says “approvals [from the FAA] may take longer.”

Elon Musk’s The Boring Company has been selected for a proposed underground transit system connecting Universal Orlando Resort and the newly opened Universal Epic Universe. 

The underground transport tunnel is designed to address the persistent gridlock surrounding International Drive. 

As noted in a blooloop report, Universal’s Shingle Creek Transit and Utility Community Development District approved a resolution showing its intent to designate The Boring Company as the contractor for the project. 

The agreement covers the full scope of the project, from the tunnel’s design, construction, and maintenance. The project has also been described in public documents as a “point-to-point innovative transportation” initiative with a 25-year agreement.

The proposed Boring Company tunnels would directly link Universal’s existing parks with Epic Universe, which sits roughly three miles away from Universal Orlando Resort. Today, buses are the only direct connection between the two destinations.

Project requirements were quite stringent. Bidders were required to demonstrate at least $75 million in bonding capacity, have a minimum of seven years of operational experience, and show prior delivery of a comparable project valued at $25 million or more within the past 15 years. The Boring Company, thanks in no small part to the Vegas Loop, meets these requirements.

The Orlando selection adds to The Boring Company’s growing portfolio of Loop-style systems. In Las Vegas, the Las Vegas Convention Center Loop has transported more than two million passengers in Tesla vehicles through underground tunnels since 2021. The greater Vegas Loop system is also under construction.

For now, residents in the area seem enthusiastic about the upcoming project. In a comment to Fox35, residents noted that the tunnels could improve traffic in the area.

“We are very congested at certain times and certain hours and that would certainly help with people not having to budget their time,” Mary Walters-Clark, a resident, stated. Another resident, Scott Heinz, echoed similar sentiments. “I think it would be a new opportunity to lessen traffic load and good for visitors as well,” he said.

The tunneling startup has started bringing its Loop projects to international locations. It recently signed a memorandum of understanding with Dubai’s Roads and Transport Authority to explore the development of a 17-kilometer underground Loop network beneath Dubai.

Elon Musk has been ranked No. 1 on Forbes’ inaugural list of America’s 250 Greatest Innovators. The ranking places Musk at the top of modern American innovation as the publication kicks off a series celebrating the nation’s 250th anniversary.

Forbes described innovation as “the grease in the economic engine” and the force that transforms industries and creates new ones. The publication highlighted that its honorees are not just inventors, but business leaders who successfully bring breakthroughs to market.

Musk, 54, was ranked No. 1 in this year’s list. Forbes noted that he is “the only person in history to have founded (or grown from nearly nothing) five companies, each with multibillion-dollar valuations, each in a different industry.” Those companies include Tesla, SpaceX, Neuralink, xAI, and The Boring Company.

Forbes’ methodology began with nearly 1,000 nominees submitted by its reporters. A panel of judges, including venture capitalist Jim Breyer, journalist Kara Swisher, and strategy expert Rita McGrath, ranked candidates based on creativity, breadth, engagement, disruption, and commercial impact. Artificial intelligence tools, including ChatGPT and Gemini, were also used to assess candidates before editors finalized the rankings.

The publication noted that more than one-third of the list consists of women and people of color, reflecting shifts in innovation and entrepreneurship over time. All individuals listed are also American citizens, though many were born abroad, including Musk himself. Musk was born in Pretoria, South Africa.

Ranked No. 2 is Jeff Bezos, 61, who Forbes credited with upending America’s $7.4 trillion retail industry through Amazon before pioneering cloud computing with Amazon Web Services. The publication highlighted that Bezos now focuses on space exploration through Blue Origin and artificial intelligence manufacturing systems at Prometheus.

At No. 3 is Bill Gates, 70, who helped launch the personal computing revolution and built Microsoft into the dominant force in workplace software. Forbes also highlighted Gates’ reinvention at age 50 as a data-driven philanthropist, including his role in helping eradicate polio from India.

The Tesla Model Y was California’s best-selling new vehicle in 2025 for the fourth straight year, despite protests against CEO Elon Musk and a changeover to the Model Y’s updated variant that caused a pause in production and deliveries early in the year.

Data from the California New Car Dealers Association (CNCDA) showed the Model Y outsold its nearest competitor by more than 50,000 units, according to KRON4.

The Model Y recorded 110,120 registrations in California in 2025. The second-best-selling vehicle, the Toyota RAV4, posted 65,604 units, followed by the Toyota Camry at 62,324. The Tesla Model 3 ranked fourth with 53,989 sales, ahead of the Honda Civic at 53,085 units.

Despite leading the state, Model Y sales have trended downward year-over-year. Registrations fell from 132,636 in 2023 to 128,923 in 2024, and then to 110,120 in 2025. Overall Tesla sales in California also declined, dropping from 238,589 in 2023 to 202,865 in 2024 and 179,656 in 2025.

The slowdown comes as the federal $7,500 EV tax credit ended, removing a key incentive that had supported electric vehicle demand for years.

“Tesla has a few advantages. Tesla, as a brand, has a status, cache, so I think folks in certain parts of the Bay. Owning a Tesla is a thing. I think that’s breaking down over time, especially given the political controversies surrounding Mr. Musk,” CNCDA President Brian Maas said.

California saw multiple anti-Musk protests in 2025, along with notable reports of consumer-owned Teslas being vandalized and attacked by protesters and activists. The fact that the Model Y and Model 3 remained strong performers in California is then a testament to the quality and value of the two vehicles. 

Tesla’s sales of the Model Y and Model 3 might see an increase this year, as the company has announced that it is sunsetting its two more expensive cars, the Model S and Model X. With the Model S and Model X retired, more consumers will likely go for the Model Y and Model 3.

“Maybe the Model S has outlived its usefulness in terms of attracting customers. It’s no surprise the ones they kept are the Model Y and Model 3,” Maas noted.
