The morning of SpaceX’s most prolific launch – the Crew Dragon Demo-2 mission – began with one question on the mind of many, why did the Falcon 9 rocket have just one second, and one second only, to launch NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS)? A simplified answer is orbital mechanics and a carefully planned out 19 hour trip around the planet.

The launch of the Falcon 9 was a highly anticipated moment, however, it was easily the most familiar part of the Demo-2 mission. Leading up to Demo-2, SpaceX had successfully launched twenty-eight Block 5 Falcon 9 boosters – the same type of booster that the Crew Dragon carrying Behnken and Hurley would launch on. The landing of the Falcon 9 on the autonomous spaceport drone ship in the middle of the Atlantic Ocean was also a familiar process that SpaceX had completed successfully a number of times.

Even the Crew Dragon capsule had a launch and mission to the space station under its belt, however, launching astronauts aboard the capsule had yet to be attempted, let alone done successfully. The least familiar part of the mission was what Crew Dragon and its occupants had to achieve once free of the Earth’s gravity well.

Once past launch and separation from the Falcon 9 first stage booster, Crew Dragon would separate from the Falcon 9 second stage, enter an initial orbit, and proceed to spend the next nineteen hours chasing the ISS around the planet. The capsule had to perform a series of burns to lift its orbit high enough to match that of the ISS for autonomous docking nineteen hours later. During the trip, Behnken and Hurley had a series of items to check off prior to initiating their crew sleep aboard Crew Dragon. A few of the items included doffing – or taking off – their SpaceX pressure suits, hosting a brief media opportunity explaining the name “Endeavour” chosen for their capsule as well as the zero-G indicator named “Tremor” chosen to ride along with them and eat their first meal in space.

The Crew Dragon also had a few jobs of its own to complete. Crew and capsule would spend about two hours performing 3 different burns of the sixteen Draco thrusters outfitted all around the Crew Dragon’s outer shell. The first phasing burn was needed to insert it into the correct orbit, followed a little while later by a boost burn to raise the capsule’s orbit even more. And lastly, a close coelliptic burn to flatten out the orbit around the Earth making it more elliptical, rather than circular matching that of the ISS. These three burns were completed while the crew was awake performing any necessary tasks. Two more burns remained to be completed, but those would need to occur much closure to docking with the ISS, one while the crew slept and one just before autonomous docking procedures were set to begin.

The fourth burn – a transfer burn – is intended to raise the capsule the final ten meters in orbital space to match that of the ISS. This burn will allow the capsule to begin its final approach toward the station. It will be completed by the SpaceX mission control ground station in Hawthorne, California while the crew sleeps. It will be a gentle burn of the Dracos lasting less than a minute.

The capsule will then burn the Draco thrusters once more for the final coelliptic burn matching its orbit directly with the ISS. At this time, the crew aboard both the Crew Dragon capsule and space station will be awake for a full day of work including the meticulous process of autonomously docking the capsule to the ISS, the opening of the hatch of Crew Dragon, and welcoming Behnken and Hurley aboard the station as members of the Expedition 63 crew.

Crew Dragon is expected to meet up with the ISS nineteen hours after liftoff. Docking with the station is set to occur on Sunday, May 31st around 10:30 am EDT/14:30 UTC. Behnken and Hurley will be welcomed aboard the station during a traditional crew welcoming ceremony that should occur about two hours after docking has been confirmed.

Elon Musk slams Bloomberg’s shocking xAI cash burn claims

Musk stated that “Bloomberg is talking nonsense.”

Elon Musk has forcefully rejected Bloomberg News’ claims that his artificial intelligence startup, xAI, is hemorrhaging $1 billion monthly. 

In a post on X, Musk stated that “Bloomberg is talking nonsense.” He also acknowledged an X user’s comment that people “really have no idea what’s at stake” with AI.

Bloomberg‘s Allegations and Musk’s Rebuttal

The Bloomberg News report painted a dire picture of xAI’s finances. Citing people reportedly familiar with the matter, the news outlet claimed that xAI burns $1 billion a month as costs for building advanced AI models outpaced the company’s limited revenues. 

Bloomberg alleged that xAI is planning to spend over half of a proposed $9.3 billion fundraising haul in three months, with a projected $13 billion loss in 2025. The report also claimed that of the $14 billion that xAI has raised since 2023, only $4 billion remained by Q1 2025. Even this amount, the news outlet alleged, will be nearly depleted in Q2.

xAI did not comment on Bloomberg‘s claims, though Elon Musk shared his thoughts on the matter on social media platform X. In response to an X user who quoted the publication’s article, Musk noted that “Bloomberg is talking nonsense.” Musk, however, did not provide further details as to why the publication’s report was fallacious.

xAI’s Bright Horizon

Despite Bloomberg‘s claims, even the publication noted that xAI’s prospects are promising. The company, now merged with X, aims to leverage the platform’s vast data archives for model training, which could reduce costs compared to rivals like OpenAI. Tapping into X also allows xAI to access real-time information from users across the globe. 

xAI’s valuation reportedly soared to $80 billion by Q1 2025, up from $51 billion in 2024. The AI startup has attracted heavyweight investors such as Andreessen Horowitz, Sequoia Capital, and VY Capital so far, and optimistic projections point to profitability possibly being attained by 2027. This would be quite a feat for xAI as OpenAI, the AI startup’s biggest rival, is still looking at 2029 as the year it could become cash flow positive.

xAI supercomputer faces lawsuit over air pollution concerns

NAACP & environmental groups are suing Elon Musk’s xAI over turbine emissions at its Colossus supercomputer site.

The xAI supercomputer, Colossus, faces a potential lawsuit from the NAACP and the Southern Environmental Law Center over pollution concerns tied to its gas-powered turbines. The facility has sparked debate over its environmental impact versus economic benefits.

The xAI data center has been operational since last year. The company used pollution-emitting turbines without an air permit, citing a 364-day exemption. Southern Environmental Law Center attorney Patrick Anderson disputed xAI’s exemption, stating: “there is no such exemption for turbines — and that regardless, it has now been more than 364 days.”

The groups issued a 60-day notice of intent to sue under the Clean Air Act, challenging xAI’s permit application under review by the Shelby County Health Department.

According to AP, critics argue the turbines emit smog, carbon dioxide, nitrogen oxides, and formaldehyde, worsening health risks in an area with cancer rates four times the national average.

“The permit itself says emissions from the site ‘will be an area source for hazardous air pollutants,’” the Southern Environmental Law Center noted, alleging Clean Air Act violations.

Opponents claim xAI installed up to 35 turbines—exceeding the 15 requested—without community oversight, straining Memphis’s power grid.

xAI responded: “The temporary power generation units are operating in compliance with all applicable laws.”

The company highlighted its economic contributions, including billions in investments, millions in taxes, and hundreds of jobs. At an April community meeting, xAI’s Brent Mayo underscored that the “tax revenue will support vital programs like public safety, health, human services, education, firefighters, police, parks, and so much more.” He projected that xAI would generate over $100 million in tax revenue by next year. The company is also investing $35 million in a power substation and $80 million in a water recycling plant.

Additionally, xAI is transitioning to sustainable power, particularly Tesla Megapacks. It is actively working on demobilizing the gas turbines.

“The temporary natural gas turbines that were being used to power the [xAI’s] Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months,” shared the Greater Memphis Chamber. xAI brought Tesla Megapack batteries and a 150-megawatt substation online earlier this year.

Despite xAI’s expansion to a second 1-million-square-foot site, the lawsuit threat underscores tensions between innovation and environmental justice.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’

Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.

A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.

The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.

However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.

He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”

Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.
