SpaceX’s Crew Dragon spaceship marches towards launch with vacuum chamber test

Published

on

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 Model S makes TIME’s list of Best Inventions

Published

on

Tesla’s flagship sedan, the Model S, has officially been named one of TIME Magazine’s Best Inventions of the 2000s. It joins its sibling, the Model 3, which made the list in 2017.

The Model S is among the most crucial developments in the automotive industry in the last century.

Just as the Ford Model T made its mark on passenger transportation, becoming the first combustion engine vehicle to be successfully developed and marketed at a time when horse and buggy were the preferred mode of transportation, the Model S revolutionized things a step further.

Although it was not the first EV to be developed, the Tesla Model S was the EV that put EVs on the map. In 2012, TIME recognized the Model S as a piece of technology that could truly transform the car industry.

The publication wrote:

“This electric four-door sedan has the lines of a Jaguar, the ability to zip for 265 miles (426 km) on one charge—that’s the equivalent of 89 m.p.g. (2.6 L/100 km)—and touchscreen controls for everything from GPS navigation to adjusting the suspension.”

Looking back, TIME was right on. The Tesla Model S was truly a marvel for its time, and it, along with the OG 2008 Roadster, can be seen as the first two EVs to push electrification to the mainstream.

As TIME described this year, the Model S “proved to be a game-changing experience for electric vehicles,” and it ended up truly catalyzing things for not only the industry, but Tesla as well.

The Model S acted as a fundraiser of sorts for future vehicles, just as the Model X did. They paved the way for the Model 3 and Model Y to be developed and offered by Tesla at a price point that was more acceptable and accessible to the masses.

The Current State of the Tesla Model S

The Model S contributes to a very small percentage of Tesla sales. The company groups the Model S with the Model X and Cybertruck in its quarterly releases.

Last year, that grouping sold 85,133 total units, a small percentage of the 1.789 million cars it delivered to customers in 2024.

Things looked to be changing for the Model S and the Model X this year, as Tesla teased some improvements to the two cars with a refresh. However, it was very underwhelming and only included very minor changes.

Lucid CEO shades Tesla Model S: “Nothing has changed in 12 years now”

It appeared as if Tesla was planning to sunset the two cars, and while it has not taken that stance yet, it seems more likely that the company will begin taking any potential options to heart.

CEO Elon Musk said a few years ago that the two cars were only produced due to “sentimental reasons.”

Tesla analysts are expecting the stock to go Plaid Mode soon

Tesla (NASDAQ: TSLA) has had a few weeks of overwhelmingly bullish events, and it is inciting several analysts to change their price targets as they expect the stock to potentially go Plaid Mode in the near future.

Over the past week, Tesla has not only posted record deliveries for a single quarter, but it has also rolled out its most robust Full Self-Driving (Supervised) update in a year. The new version is more capable than ever before.

Tesla Full Self-Driving v14.1 first impressions: Robotaxi-like features arrive

However, these are not the only things moving the company’s overall consensus on Wall Street toward a more bullish tone. There are, in fact, several things that Tesla has in the works that are inciting stronger expectations from analysts in New York.

TD Cowen

TD Cowen increased its price target for Tesla shares from $374 to $509 and gave the stock a ‘Buy’ rating, based on several factors.

Initially, Tesla’s positive deliveries report for Q3 set a bullish tone, which TD Cowen objectively evaluated and recognized as a strong sign. Additionally, the company’s firm stance on ensuring CEO Elon Musk is paid is a positive, as it keeps him with Tesla for more time.

Elon Musk: Trillionaire Tesla pay package is about influence, not wealth

Musk, who achieved each of the tranches on his last pay package, could obtain the elusive title as the world’s first-ever trillionaire, granted he helps Tesla grow considerably over the next decade.

Stifel

Stifel also increased its price target on Tesla from $440 to $483, citing the improvements Tesla made with its Full Self-Driving suite.

The rollout of FSD v14.1 has been a major step forward for the company. Although it’s in its early stages, Musk has said there will be improved versions coming within the next two weeks.

Stifel raises Tesla price target by 9.8% over FSD, Robotaxi advancements

Analysts at the firm also believe the company has a chance to push an Unsupervised version of FSD by the end of the year, but this seems like it’s out of the question currently.

It broke down the company’s FSD suite as worth $213 per share, while Robotaxi and Optimus had a $140 per share and $29 per share analysis, respectively.

Stifel sees Tesla as a major player not only in the self-driving industry but also in AI as a whole, which is something Musk has truly pushed for this year.

UBS

While many firms believe the company is on its way to doing great things and that stock prices will rise from their current level of roughly $430, other firms see it differently.

UBS said it still holds its ‘Sell’ rating on Tesla shares, but it did increase its price target from $215 to $247.

It said this week in a note to investors that it adjusted higher because of the positive deliveries and its potential value with AI and autonomy. However, it also remains cautious on the stock, especially considering the risks in Q4, as nobody truly knows how deliveries will stack up.

In the last month, Tesla shares are up 24 percent.

Tesla has landed permission to begin testing its Full Self-Driving suite in a new country: Sweden.

Tesla has been working to expand its Full Self-Driving suite across the world. Currently, it is available in seven countries: the United States, Canada, Mexico, Puerto Rico, Australia, New Zealand, and China, where it is referred to as “City Autopilot.”

Capabilities of the Full Self-Driving suite differ in each region based on the approvals given to Tesla by regulatory agencies.

In Europe, Tesla has been attempting for a long time to launch FSD in various countries, but regulatory red tape has been prolonging the company’s ability to launch the suite.

However, Sweden appears to be ready to allow Tesla to test FSD in some passenger and public locations, according to the country’s Transport Agency.

On X, a Swedish Tesla owner named Alexander Kristensen, says he received direct confirmation from the Transport Agency that Tesla has “received permission to test automated vehicles.”

The full email said:

“Tesla received permission to test automated vehicles last week. This includes three vehicles and all state highways and expressways in Sweden.”

Tesla has already been working with the Swedish Transport Agency on the first steps of Full Self-Driving’s approval. The company and the Transport Agency spent two weeks assessing data gathered during a Formal Site Assessment Test, or SAT.

Based on the communication from the Transport Agency to Kristensen, it appears the company has passed the SAT and will now be able to perform its own testing within the market.

This approval seems similar to the approval Tesla received in U.S. states for Robotaxi operation. Nevada and Arizona have both given Tesla approval for Robotaxi testing, but passengers are not allowed in the vehicles quite yet.

Instead, company employees perform the testing, which is likely what will go on in Sweden until the Transport Agency gives the company a green light to roll FSD software out to customers.
