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.

SpaceX just launched a secret payload from California

SpaceX launched a classified Space Force mission from Vandenberg, revealing almost nothing about its payload.

SpaceX launched a classified Falcon 9 mission for the U.S. Space Force from Vandenberg Space Force Base on Saturday night, and the government released almost nothing about what was on board. The mission, designated USSF-366, lifted off from Space Launch Complex 4E with a window that opened at 9:52 p.m. ET and ran into the early hours of Sunday, according to SpaceX’s own mission page, which described the payload only as classified. SpaceX confirmed the launch on its X account and pointed viewers to a livestream that began roughly ten minutes before liftoff.


The lack of detail did not stop analysts from filling in the blanks. Independent tracking of the rocket’s stage drop zones matched the pattern SpaceX has used on previous Starlink Group 15 missions, according to reporting from Outer Space Today, which pointed to Starshield as the likely payload rather than a one off government satellite. Starshield is SpaceX’s national security product, a version of the Starlink satellite bus built to Pentagon specifications for earth observation, communications and hosted payloads. Unlike consumer Starlink, government agencies do not have to disclose what Starshield satellites are actually doing once they reach orbit.

USSF-366 is the latest entry in a steady flow of classified and semi classified work between SpaceX and the Space Force. The company picked up a $178.5 million task order in April to launch missile tracking satellites for the Space Development Agency, as Teslarati reported at the time, and followed that in July with a $1.6 billion award covering 18 more Falcon 9 missions from Vandenberg through the end of 2027, also detailed by Teslarati. Add those contracts up and SpaceX’s Pentagon business for 2026 alone tops $8 billion.

SpaceX scores another massive Pentagon deal to support military satellites

The Falcon 9 that flew Saturday landed back near the launch site, producing the sonic booms that have become routine for residents near Vandenberg. What is less routine is how little the public will likely ever learn about what the rocket carried. SpaceX and the Space Force have not confirmed the Starshield connection, and government satellite programs built on commercial buses rarely get identified beyond a mission number and a general orbit. For a company that live streams almost everything else it does, from Starship test flights to Optimus robot demos, USSF-366 is a reminder that some of SpaceX’s busiest work now happens entirely out of public view.

Tesla V2L adapter for Model Y stirs up a new complaint among owners

Published

On Friday, Tesla launched the Outlet Adapter that enabled Vehicle-to-Load (V2L) energy transfer, meaning owners could essentially utilize their cars as a power source for things like laptops, electric grills, or string lights.

However, even owners of some of the newest builds of the Model Y are finding out that their cars are not compatible with the new $80 accessory, stirring up a new complaint among members of the community.

Tesla launches V2L Outlet Adapter for Premium Model Y in the U.S.

Upon the release of the Outlet Adapter on Friday, I signed into my Tesla account to order the accessory. However, I was met with the dreaded “This product is not compatible with your 2026 Model Y” message at the bottom of the screen.

Some said their accounts also displayed the same message, but they ordered anyway. However, they might be surprised to find that this is no mistake; some of the newest Model Ys do not have the appropriate Power Conversion System (PCS). Mine, which was ordered on this day last year and delivered on August 31, has the old 48A, single-phase PCS.

Vehicles with the new, two-piece PCS are able to utilize V2L features on their cars:

Obviously, it’s disappointing. Many owners have taken delivery this year and still can not utilize the Outlet Adapter because their cars feature the old PCS:

It looks like if you have one of these older PCS units, you can upgrade, but the parts alone are $1,750, and that’s before Tesla adds labor for installing. It is honestly more logical to get some kind of portable power supply or power station at that point.

It is great that Tesla has enabled V2L for Model Y vehicles, but it is also unfortunate that vehicles that are less than one year old are not able to take advantage of this awesome new feature.

With that being said, it truly is a first-world problem; can you really complain when Full Self-Driving is available, maintenance is incredibly inexpensive, and the car has been so good through a year of ownership?

Tesla has launched a new Vehicle-to-Load (V2L) Outlet Adapter for Premium Model Y vehicles in the United States, meaning you can now power devices like laptops or light strings with your vehicle’s battery.

It appears the capability will be available for any Model Y Premium trim, including those that were purchased prior to the Adapter being launched. It will also only impact Juniper Model Y vehicles, so the first-gen owners will unfortunately not have access to this capability.

If your Model Y was purchased before Tesla renamed the trim levels to “Premium” and “Standard,” it does not seem to be compatible. My Model Y is technically a Premium build, as it is the Long Range All-Wheel-Drive. However, Tesla says it is not compatible with my vehicle.

For $80, you can now utilize your car as a portable charger for small appliances or devices. This is perfect for things like tailgates, concerts, or camping, as you can now plug in devices that you might use. Those string lights for camping? That laptop for the other games that are on at the tailgate?

They’ll both utilize energy from your Tesla’s battery to be powered. This is the first time Tesla has expanded the capability to vehicles outside of the Model Y Performance and Cybertruck. However, this feature has been highly requested by owners for an extended period of time.

Tesla launched the Outlet Adapter in China last year:

You will need the Mobile Connector to operate the Outlet Adapter: the Outlet Adapter will plug into the main housing of the Mobile Connector, where the appropriate adapter to charge your vehicle will plug in.

It is rated for 120 volts and 20 amps, and has a max power rating of 2.4kW.

You can buy it here from Tesla for $80.
