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

GM takes latest step to avoid disaster as EV efforts get derailed
There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.
General Motors has taken its latest step to avoid financial disaster as its electric vehicle efforts have been widely derailed.
GM’s electric vehicle manufacturing efforts started off hot, and CEO Mary Barra seemed to have a real hold on how the industry and consumers were starting to evolve toward sustainable powertrains. Even former President Joe Biden commended her as being a major force in the global transition to EVs.
However, the company’s plans have not gone as they’ve drawn them up. GM has reported some underwhelming delivery figures in recent quarters, and with the loss of the $7,500 tax credit, the company is planning for what is likely a substantial setback in its entire EV division.
Earlier this month, the company reported it would include a $1.6 billion charge in its quarterly earnings results from EV investments. It was the first true sign that things with GM’s EV projects were going to slow down.
There was an even larger step taken this morning, as the Detroit Free Press reported that GM was idling its Factory Zero plant in Michigan until late November, placing about 1,200 workers on indefinite layoff status.
This is in addition to the 280 employees it has already laid off after production cuts that happened earlier this year at the Detroit-Hamtramck plant.
After November 24, GM will bring back 3,200 people to work until January 5 to operate both shifts. On January 5, GM is expected to keep 1,200 workers on indefinite layoff.
GM is not the only legacy automaker to make a move like this, as Ford has also started to make a move that reflects a cautious tone regarding how far and how committed it can be to its EV efforts.
After the tax credit was lost, it seemed to be a game of who would be able to float their efforts longest without the government’s help. Tesla CEO Elon Musk long said that the loss of these subsidies would help the company and hurt its competitors, and so far, that is what we are seeing.
Elon Musk was right all along about Tesla’s rivals and EV subsidies
However, Tesla still has some things to figure out, including how its delivery numbers will be without the tax credit. Its best quarter came in Q3 as the credit was expiring, but Tesla did roll out some more affordable models after the turn of the quarter.

Tesla expands Robotaxi geofence, but not the garage
This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.
Tesla has expanded its Robotaxi geofence four times, once as recently as this week.
However, the company has seemingly kept its fleet size relatively small compared to the size of the service area, making some people — even pro-Tesla influencers — ask for more transparency and an expansion of the number of vehicles it has operating.
Over the past four months, Tesla has done an excellent job of maintaining growth with its service area in Austin as it continues to roll out the early stages of what is the Robotaxi platform.
The most recent expansion brought its size from 170 square miles (440.298 sq. km) to 243 square miles (629.367 sq. km).
Tesla sends clear message to Waymo with latest Austin Robotaxi move
This has broadened its geofence to nearly three times the size of Waymo’s current service area, which is great from a comparative standpoint. However, there seems to be something that also needs to be expanded as the geofence gets larger: the size of the Robotaxi fleet.
Tesla has never revealed exactly how many Model Y vehicles it is using in Austin for its partially driverless ride-hailing service (We say partial because the Safety Monitor moves to the driver’s seat for freeway routes).
When it first launched Robotaxi, Tesla said it would be a small fleet size, between 10 and 20 vehicles. In late August, after its second expansion of the service area, it then said it “also increased the number of cars available by 50 percent.”
The problem is, nobody knows how many cars were in the fleet to begin with, so there’s no real concrete figure on how many Robotaxis were available.
This has caused some frustration for users, who have talked about the inability to get rides smoothly. As the geofence has gotten larger, there has only been one mentioned increase in the fleet.

Really think Tesla needs to add more cars to the fleet in Austin. Has become tougher and tougher to use the service reliably @elonmusk pic.twitter.com/KHqea3oUxU

Tesla did not reveal any new figures or expansion plans in terms of fleet size in the recent Q3 Earnings Call, but there is still a true frustration among many because the company will not reveal an exact figure.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
Tesla has recalled 6,197 Cybertrucks for a light bar adhesive issue that was utilized by Service to install the aftermarket part.
According to the National Highway Traffic Safety Administration (NHTSA), impacted vehicles may have had the light bar “inadvertently attached to the windshield using the incorrect surface primer.”
Tesla identified an issue with the light bar’s adhesion to glass back in February and worked for months to find a solution. In October, the company performed chemical testing as a part of an engineering study and determined the root cause as the BetaPrime primer it utilized, figuring out that it was not the right surface priming material to use for this specific application.
On October 20, Tesla issued a voluntary recall of the impacted vehicles and has identified 619 warranty claims and just a single field report that is related to the issue.
The component is manufactured by a Romanian company called Hella Romania S.R.L., but the issue is not the primer’s quality. Instead, it is simply the fact that it is not the correct adhesive for this specific type of application.
Tesla says there are no reports of injuries or deaths due to this issue, and it will be resolved. In the 473 report that the NHTSA released this morning, Tesla said:
“At no charge to customers, Tesla will inspect the service-installed optional off-road light bar accessory for delamination or damage and if either is present, replace the light bar with a new light bar adhered with tape and a positive mechanical attachment. If no delamination or damage is present, Tesla will retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
This is the third recall applied to Cybertrucks this year, as one on March 18 highlighted the potential for exterior trim panels to detach while driving, and another earlier this month when the NHTSA said its front parking lights were too bright.
Tesla resolved the first with a free assembly replacement, while the headlight issue was fixed with an Over-the-Air software update earlier this week. Owners said there was a noticeable difference in the brightness of the lights now compared to previously.
