SpaceX has published the latest photo of its next-generation Crew Dragon spacecraft, showing the crewed vehicle preparing to be put through its paces inside a NASA thermal vacuum chamber located in Cleveland, Ohio. If the tests are completed without issue, the Dragon’s next destination will be Cape Canaveral, Florida, where it will prepare for an inaugural launch targeted for the fourth quarter of 2018.

In the photo released on June 20th, SpaceX’s DM-1 Crew Dragon capsule (C202 in shorthand: [C]apsule, Dragon [2], serial number [02]) is seen being craned by SpaceX technicians into the thermal vacuum chamber at NASA’s Plum Brook testing facilities. Located in Ohio, Plum Brook’s vacuum chamber is unique because of both its size and its ability to fairly accurate replicate the actual environment faced by satellites and spacecraft once in space. Most importantly, this includes the extreme thermal conditions those vehicles are subjected to by constant ~90-minute day-night cycles in low Earth orbit (LEO).

Without Earth’s cozy atmosphere to act as both a heat sink and insulating blanket once on orbit, there is simply nothing there to protect spacecraft like Crew Dragon from the absolute extremes of direct solar radiation (sunlight), total darkness, and a complete lack of cooling by conduction and convection. In order to avoid overheating, Crew Dragon thus needs to bring along its own means of cooling in the form of onboard radiators to shed excess heat. The use of white paint on spacecraft further aids this process by selectively preventing the absorption of solar radiation while simultaneously efficiently emitting in infrared wavelengths.

How to prep your Dragon

Crew Dragon’s primary radiators are elegantly integrated into vertical panels installed on the cylindrical bottom segment, known as the trunk, while the craft’s power source – solar panels in this case – are installed in a curved array on the opposite side of the trunk. Intriguingly, the trunks displayed in the two most recent photos of the DM-1 Crew Dragon appear to be almost completely different, and the trunk at Plum Brook does not appear to have its solar arrays or radiators installed. Nominally, SpaceX would use the thermal vacuum capabilities of the Ohio facility to fully vet Crew Dragon’s ability to maintain optimal temperatures on orbit, but the particularly tests planned for the DM-1 capsule and trunk may be of a slightly different type.

Regardless, after testing at Plum Brook is completed, the DM-1 Crew Dragon capsule will be shipped to a newly-constructed processing facility in Cape Canaveral, Florida, while it’s understood that the trunk installed in SpaceX’s June 20th photo will be returned to the Hawthorne, CA factory to be outfitted with flight hardware (presumably including cameras, radiators, solar arrays, and a healthy amount of insulation). It’s unclear when the two segments of DM-1 will part ways and head on to their next destinations, but it’s likely that testing at Plum Brook will last for at least a handful of weeks.

Birds of a feather

In the meantime, several additional Crew Dragon capsules/trunks and the Falcon 9 Block 5 rockets that will launch them are in a variety of states of fabrication and assembly at SpaceX’s Hawthorne factory. B1051, the Block 5 booster assigned to the first uncrewed Demo-1 launch of Crew Dragon, was reported by NASA to be undergoing propellant tank integration in March 2018, implying that the rocket should be at or near the final stages of integration, and will likely ship to McGregor, Texas for static fire testing late this summer.

As of June 15th, SpaceX’s third Falcon 9 Block 5 booster was vertical on the Texas test stand, likely nearing its own static fire test before being shipped to SpaceX’s Vandenberg Air Force Base launch facilities for the July 20th launch of Iridium-7. While possible that a booster slipped past the watchful eyes and ears of SpaceX enthusiast observers, it’s probable that the rocket currently in McGregor is B1048, implying that a minimum of two additional booster shipments and Texas test programs remain before B1051 can be prepped to launch SpaceX’s first Crew Dragon mission. At the current marginally accelerated booster production and shipment schedule (~ 30-day cadence), B1051 would be expected to leave Hawthorne for Texas no earlier than (NET) late August or early September. This meshes with a recent comment from Commercial Crew astronaut Suni Williams:

“I think we’re going to get the [uncrewed[ demo flights probably by the end of the year, maybe a little after that . . . and then the crew demo missions next year.”

Anticipating acceptance and prelaunch testing that is far more extensive and time-consuming than typically seen with SpaceX’s commercial missions, it’s safe to bet that the first uncrewed Crew Dragon mission – DM-1 – will launch from Kennedy Space Center in November or December 2018. While those operations proceed over the course of the rest of this year, SpaceX expects roughly 10 additional Falcon 9 and Falcon Heavy launches to occur. It’s gonna be a busy H2.

Tesla has begun exporting Megapack battery systems from its Shanghai Megafactory, with the first shipment departing for Australia on Friday. This marks a key step in Tesla Energy’s expansion into the global energy storage industry, utilizing its new China-based Megafactory to supply several new markets.

Tesla Asia celebrated the Shanghai Megafactory’s first Megapack exports through its official social media account on X.

Tesla Megapacks in Focus

The Tesla Megapack is capable of storing 3.9 MWh of energy, and they are designed for grid use. As per Tesla in its official website, each Megapack battery has enough energy to power an average of 3,600 homes for one hour. The Megapack is designed to be infinitely scalable as well, making it a good fit for large-scale sustainable energy projects.

The Shanghai Megafactory

The Shanghai Megafactory began production in early 2025, a record eight months after its May 2024 groundbreaking. With an initial output of 10,000 units annually, equal to about 40 GWh, the Shanghai Megafactory has the potential to significantly boost Tesla’s battery storage deployments.

As per a report from Xinhua News Agency, Tesla is expecting its energy deployments to rise 50% year-over-year this 2025.

Tesla Leaders on the Shanghai Megafactory

Mike Snyder, vice president of energy and charging at Tesla, previously outlined the potential of the Shanghai Megafactory. “Megafactory gives us the ability to scale production and efficiency. We can lower logistics costs as well as product costs, and grow the business to new markets,” he stated.

The Shanghai Megafactory also seems to be part of Tesla’s efforts to grow its presence in China, which was highlighted by CEO Elon Musk during a meeting with Chinese Premier Li Qiang. During their meeting, Musk reportedly stated that “Tesla is willing to deepen cooperation with China and achieve more win-win results.”

Shark Tank’s O’Leary roasts Tim Walz over Tesla stock hate session

Shark Tank personality and legendary investor Kevin O’Leary roasted former Vice Presidential nominee Tim Walz over his comments regarding Tesla shares earlier this week.

Walz, a Minnesota Democrat, said that he recently added Tesla (NASDAQ: TSLA) to his Apple Stocks app so he could watch shares fall as they have encountered plenty of resistance in 2025 so far. He said that anytime he needs a boost, he looks at Tesla shares, which are down 36 percent so far this year:

Walz, among many others, has been critical of Tesla and Elon Musk, especially as the CEO has helped eliminate excess government spending through the Department of Government Efficiency (DOGE).

However, Kevin O’Leary, a legendary investor, showed up on CNN after Walz’s comments to give him a bit of a reality check. O’Leary essentially called Walz out of touch for what he said about Tesla shares, especially considering Tesla made up a good portion of the Minnesota Retirement Fund.

As of June 2024, the pension fund held 1.6 million shares of Tesla stock worth over $319.6 million:

O’Leary continued to slam Walz for his comments:

“That poor guy didn’t check his portfolio and his own pension plan for the state. It’s beyond stupid what he did. What’s the matter with that guy? He doesn’t check the well-being of his own constituents.”

He even called Walz “a bozo” for what he said.

Of course, Walz’s comments are expected considering Musk’s support for the Trump Administration, as the Tesla CEO was a major contributor to the 45th President’s campaign for his second term.

However, it seems extremely out of touch that Walz made these comments without realizing the drop was potentially hurting his fund. While we don’t know if the fund has sold its entire Tesla holdings since June, as a newer, more recent report has not been released yet, it seems unlikely the automaker’s shares are not still making up some portion of the fund.

Alleged Tesla attackers could face between 5 to 20 years in prison if convicted, warns the Justice Department.

According to U.S. Attorney General Pamela Bondi, three people have been accused of using Molotov cocktails to set Tesla vehicles and charging stations on fire. Prosecutors recently announced the arrests of the three defendants.

“Let this be a warning: if you join this wave of domestic terrorism against Tesla properties, the Department of Justice will put you behind bars,” noted Bondi.

Bondi echoed the words of Special Agent Spencer Evans from the FBI’s Las Vegas Field Office. Evans emphasized to the public that setting Tesla vehicles and charging stations on fire is a federal crime.

The first defendant in the Tesla arson cases is Lucy Grace Nelson who has pleaded not guilty and been released on bond. A criminal complaint states that Nelson was spotted at a Tesla dealership in Loveland, Colorado, a few times in January and February 2025. The 42-year-old was charged with possession of a destructive device and malicious destruction of property after police found a container of gasoline, a box of bottles, and wicks in Nelson’s car.

The second person arrested in Tesla’s arson cases is Adam Matthew Lansky, who has been accused of throwing eight Molotov cocktails at a Tesla dealership in Salem, Oregon. The 41-year-old is detained while awaiting trial and has not entered a plea.

The last alleged Tesla arsonist is Daniel Clarke-Pounder, who has been charged with throwing Molotov cocktails at Tesla charging stations in North Charleston, South Carolina. Witnesses reported seeing a man spray-paint a profane message about President Trump and the words “Long Live Ukraine,” in the Tesla parking lot. The 24-year-old was released on a $10,000 bond and has not yet entered a plea.

Attacks on Tesla cars, charging stations, and stores have spread throughout the United States recently as more people take their anger for Elon Musk out on the American car manufacturer. Luckily, no one has been injured or died from any of the attacks.
