Relativity Space’s first 3D-printed rocket goes vertical for launch debut

Published

Relativity Space’s first 3D-printed Terran 1 rocket has rolled out to the startup’s Florida pad and been raised vertical ahead of its launch debut.

Founded in 2015, the private Los Angeles-based spaceflight company shipped its first complete rocket prototype to Florida in June 2022. Prior to that major milestone, Relativity qualified Terran 1’s orbital second stage at leased facilities located at NASA’s Stennis Space Center in southwest Mississippi, and – alongside a nosecone and interstage – arrived at Cape Canaveral Space Force Station (CCSFS) more or less ready to fly.

The last six months have been almost exclusively dedicated to testing Terran 1’s larger and more powerful first stage (booster) as thoroughly as possible. Instead of building a dedicated booster test stand in Mississippi, Relativity chose to modify Terran 1’s lone LC-16 launch pad for the crucial task. Ultimately, the startup was able to complete a large amount of booster testing on the ground, significantly increasing the odds that Terran 1 will perform as expected when it lifts off for the first time.

Beginning with cryogenic proofing, propellant loading, ‘spin starts,’ and several shorter static fire tests, Relativity’s first Terran 1 booster test campaign culminated with two long-duration static fires in September 2022. The final 57 and 82-second static fires weren’t quite the “full mission duration” tests Relativity had hoped for, but the company concluded that the data gathered was enough to clear the booster for flight.

According to Ellis, one of the most important insights gained from those tests was into Terran 1’s uncharacteristically complex autogenous pressurization system – unprecedented for such a small rocket. Generally speaking, orbital-class rockets store helium gas in small ultra-high-pressure tanks (COPVs) and use helium to pressurize their propellant tanks as they are drained of propellant. Autogenous pressurization refers to an alternative in which a portion of a rocket’s liquid oxidizer and fuel are turned into hot gas and injected back into their respective tanks to pressurize them.

Helium is extremely expensive and an unrenewable resource. In theory, autogenous pressurization – at the cost of being significantly more complex and finicky – can also reduce the amount of dry mass reserved for tank pressurization. While Terran 1 wasn’t able to complete a full-duration static fire, the tests it did complete showed Relativity that its autogenous pressurization systems are unlikely to be a problem in flight, mostly eliminating a major source of uncertainty.

Following the final 82 or 88-second static fire, Relativity returned Terran 1’s booster to LC-16’s hangar and shifted its focus to fully assembling the two-stage rocket and finishing the launch pad. In early December, the company announced that it had fully assembled the first Terran 1. Days later, the rocket was installed on the pad’s “Transporter Erector.” The T/E responsible for transporting the rocket and raising it vertical, but it also needs to connect the rocket to ground systems (propellant, power, comms, etc.) and hold it down before liftoff.

On or around December 6th, Terran 1 rolled out to the pad and was raised vertical soon after. According to Ellis, all that stands between Terran 1 and its first launch is a short integrated static fire test and a launch license from the Federal Aviation Administration (FAA). It’s impossible to say how long the FAA will take, but it’s likely that Relativity will be technically ready to launch just a handful of weeks from now.

Beyond building a relativity impressive rocket, Relativity’s claim to fame is large-scale 3D printing. The startup says that the first Terran 1 rocket – booster, upper stage, fairing, engines, and all – is 85% 3D-printed by mass and the largest single 3D-printed object ever built. Terran 1 reportedly weighs around 9.3 tons (20,500 lb) empty; will measure around 33 meters (110 ft) tall and 2.3 meters (7.5 ft) wide; and will produce around 90 tons (~200,000 lbf) of thrust at liftoff. The rocket is designed to launch 1.25 tons (~2750 lb) to low Earth orbit for $12 million

Tesla starts removing outright Full Self-Driving purchase option at time of order

Published

Tesla has chosen to axe the ability to purchase Full Self-Driving outright from a select group of cars just days after CEO Elon Musk announced the company had plans to eliminate that option in February.

The company is making a clear-cut stand that it will fully transition away from the ability to purchase the Full Self-Driving suite outright, a move that has brought differing opinions throughout the Tesla community.

Earlier this week, the company also announced that it will no longer allow buyers to purchase Full Self-Driving outright when ordering a pre-owned vehicle from inventory. Instead, that will be available for $99 per month, the same price that it costs for everyone else.

The ability to buy the suite for $8,000 for a one-time fee at the time of order has been removed:

This is a major move because it is the first time Tesla is eliminating the ability to purchase FSD outright for one flat fee to any of its vehicles, at least at the time of purchase.

It is trying to phase out the outright purchase option as much as it can, preparing people for the subscription-based service it will exclusively offer starting on February 14.

In less than a month, it won’t be available on any vehicle, which has truly driven some serious conversation from Tesla owners throughout the community.

There’s a conflict, because many believe that they will now lose the ability to buy FSD and not pay for it monthly, which is an attractive offer. However, others believe, despite paying $8,000 for FSD, that they will have to pay more money on top of that cost to get the unsupervised suite.

Additionally, CEO Elon Musk said that the FSD suite’s subscription price would increase over time as capabilities increase, which is understandable, but is also quite a conflict for those who spent thousands to have what was once promised to them, and now they may have to pay even more money.

Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys

These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.

Tesla Robotaxi has a highly-requested hardware feature that is not available on typical Model Ys that people like you and me bring home after we buy them. The feature is something that many have been wanting for years, especially after the company adopted a vision-only approach to self-driving.

After Tesla launched driverless Robotaxi rides to the public earlier this week in Austin, people have been traveling to the Lone Star State in an effort to hopefully snag a ride from one of the few vehicles in the fleet that are now no longer required to have Safety Monitors present.

BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor

Although only a few of those completely driverless rides are available, there have been some new things seen on these cars that are additions from regular Model Ys, including the presence of one new feature: camera washers.

With the Model Y, there has been a front camera washer, but the other exterior “eyes” have been void of any solution for this. For now, owners are required to clean them manually.

In Austin, Tesla is doing things differently. It is now utilizing camera washers on the side repeater and rear bumper cameras, which will keep the cameras clean and keep operation as smooth and as uninterrupted as possible:

These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.

This is the first time we are seeing them, so it seems as if Safety Monitors might have been responsible for keeping the lenses clean and unobstructed previously.

However, as Tesla transitions to a fully autonomous self-driving suite and Robotaxi expands to more vehicles in the Robotaxi fleet, it needed to find a way to clean the cameras without any manual intervention, at least for a short period, until they can return for interior and exterior washing.

Tesla makes big Full Self-Driving change to reflect future plans

Tesla made a dramatic change to the Online Design Studio to show its plans for Full Self-Driving, a major part of the company’s plans moving forward, as CEO Elon Musk has been extremely clear on the direction moving forward.

With Tesla taking a stand and removing the ability to purchase Full Self-Driving outright next month, it is already taking steps to initiate that with owners and potential buyers.

On Thursday night, the company updated its Online Design Studio to reflect that in a new move that now lists the three purchase options that are currently available: Monthly Subscription, One-Time Purchase, or Add Later:

This change replaces the former option for purchasing Full Self-Driving at the time of purchase, which was a simple and single box to purchase the suite outright. Subscriptions were activated through the vehicle exclusively.

However, with Musk announcing that Tesla would soon remove the outright purchase option, it is clearer than ever that the Subscription plan is where the company is headed.

The removal of the outright purchase option has been a polarizing topic among the Tesla community, especially considering that there are many people who are concerned about potential price increases or have been saving to purchase it for $8,000.

This would bring an end to the ability to pay for it once and never have to pay for it again. With the Subscription strategy, things are definitely going to change, and if people are paying for their cars monthly, it will essentially add $100 per month to their payment, pricing some people out. The price will increase as well, as Musk said on Thursday, as it improves in functionality.

Those skeptics have grown concerned that this will actually lower the take rate of Full Self-Driving. While it is understandable that FSD would increase in price as the capabilities improve, there are arguments for a tiered system that would allow owners to pay for features that they appreciate and can afford, which would help with data accumulation for the company.

Musk’s new compensation package also would require Tesla to have 10 million active FSD subscriptions, but people are not sure if this will move the needle in the correct direction. If Tesla can potentially offer a cheaper alternative that is not quite unsupervised, things could improve in terms of the number of owners who pay for it.
