SpaceX installs Super Heavy booster on launch mount with giant robot arms

Published

on

SpaceX has transported the most powerful rocket booster ever assembled to its Starbase orbital launch site (OLS) and used giant robotic arms to install it.

It’s not the first such trip for Starship’s Super Heavy first stage in general, nor for this specific booster, which is known as Booster 7 or B7. Booster 7 first headed to the pad on March 31st and successfully completed two major cryogenic proof tests, but was then severely damaged during a subsequent structural stress test. After a few weeks of repairs back at the factory, B7 rolled to the pad a second time and completed a third cryoproof test and returned to the factory on May 14th, where it stayed until June 23rd.

After almost six weeks of additional work, Booster 7 rolled to the launch pad for the third time – possibly its last trip.

Even Booster 7’s first rollout wasn’t unprecedented, however. In September 2021, Booster 4 – an earlier prototype with fewer engines, less thrust, and several other differences – arrived at the launch site with 29 Raptor V1 engines installed. Over the next six months, SpaceX slowly finished the booster, conducted a handful of proof tests, and eventually performed three ‘full-stack’ tests with Starship S20. For awhile, SpaceX hoped to eventually fly B4 and S20 on Starship’s first orbital launch attempt, but that plan never came close to fruition.

Booster 4 was particularly underwhelming and never even attempted a single static fire despite having all 29 of its engines fully installed and encased inside a shell-like heat shield. Thankfully, Booster 7 appears to have a much better chance of at least attempting one or several static fires, even if there’s no guarantee that it will make it through that test campaign in good enough condition to support Starship’s orbital launch debut.

SpaceX used the six weeks Booster 7 spent back in a factory assembly bay to finish installing aerocovers, surfaces known as chines or strakes, car-sized grid fins, Starlink internet dishes, and – most importantly – 33 upgraded Raptor V2 engines. Combined, Booster 7 should be able to produce up to 7600 metric tons (~16.8M lbf) of thrust – 41% more thrust than Booster 4 was theoretically capable of. Crucially, SpaceX also finished installing Booster 7’s Raptor heat shield in the same period, completing in six weeks work that took Booster 4 more like half a year.

That is likely because testing Booster 4, for whatever reason, just wasn’t a priority for SpaceX. Preparing Booster 7 for static fire testing, however, is clearly a front-and-center priority in 2022. With its heat shield and all 33 Raptors installed, Booster 7 will be ready to kick off static fire testing almost as soon as it’s installed on Starbase’s orbital launch mount.

B7’s 33 Raptor engines

According to CEO Elon Musk, Booster 7 will start by igniting just one or a few Raptor engines. SpaceX has never ignited more than six Raptor V1 engines simultaneously and never tested more than three engines at a time on a Super Heavy booster. That plan could have easily changed, however. Either way, Super Heavy B7 will be treading significantly new ground. Even before actual static fires begin, Booster 7 will also need to complete one or more wet dress rehearsals (WDRs), a test that exactly simulates a launch but stops just before the moment of ignition.

If SpaceX attempts a full wet dress rehearsal, in which the booster would be filled with more than 3000 tons (~6.6M lb) of liquid oxygen (LOx) and liquid methane (LCH4), it would be a first for Super Heavy and just as big of a test of the orbital launch site. Booster 7 will also need to test out its autogenous pressurization, which replaces helium with hot oxygen and methane gas to pressurize the rocket’s propellant tanks.

Several hours after Super Heavy B7 arrived (for the third time) at the orbital launch site, SpaceX used two giant arms attached to the pad’s launch tower to lift the ~70-meter (~230 ft) tall rocket onto the launch mount. While Musk says that the ultimate goal is to use those arms to catch Starship and Super Heavy out of mid-air, their current purpose is to take the place of the tall and unwieldy crane that would otherwise need to be used to lift either stage. The arms are an extremely complex solution but they do allow SpaceX to lift, install, and remove Starship stages remotely and insulate those processes from wind conditions, which cranes are sensitive to.

Once fully secured by the mount’s 20 hold-down clamps, the booster will be connected to ground systems and SpaceX can prepare B7 to start the next stage of preflight testing as early as Monday, June 27th.

Tesla expands its branded ‘For Business’ Superchargers

Tesla has expanded its branded ‘For Business’ Supercharger program that it launched last year, as yet another company is using the platform to attract EV owners to its business and utilize a unique advertising opportunity.

Francis Energy of Oklahoma is launching four Superchargers in Norman, where the University of Oklahoma is located. The Superchargers, which are fitted with branding for Francis Energy, will officially open tomorrow.

It will not be the final Supercharger location that Francis Energy plans to open, the company confirmed to EVWire.

Back in early September, Tesla launched the new “Supercharger for Business” program in an effort to give businesses the ability to offer EV charging at custom rates. It would give their businesses visibility and would also cater to employees or customers.

“Purchase and install Superchargers at your business,” Tesla wrote on a page on its website for the new program. “Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”

The first site opened in Land O’ Lakes, Florida, which is Northeast of Tampa, as a company called Suncoast launched the Superchargers for local EV owners.

The program also does a great job at expanding infrastructure for EV owners, which is something that needs to be done to encourage more people to purchase Teslas and other electric cars.

Francis Energy operates at least 14 EV charging locations in Oklahoma, spanning from Durant to Oklahoma City and nearly everywhere in between. Filings from the company, listed by Supercharge.info, show the company’s plans to convert some of them to Tesla Superchargers, potentially utilizing the new Supercharger for Business program to advertise.

Moving forward, more companies will likely utilize Tesla’s Supercharger for Business program as it presents major advantages in a variety of ways, especially with advertising and creating a place for EV drivers to gain range in their cars.

Tesla Cybercab ‘breakdown’ image likely is not what it seems

Published

on

Tesla Cybercab is perhaps the most highly-anticipated project that the company plans to roll out this year, and as it is undergoing its testing phase in pre-production currently, there are some things to work through with it.

Over the weekend, an image of the Cybercab being loaded onto a tow truck started circulating on the internet, and people began to speculate as to what the issue could be.

The Cybercab can clearly be seen with a Police Officer and perhaps the tow truck driver by its side, being loaded onto, or even potentially unloaded from, the truck.

However, it seems unlikely it was being offloaded, as its operation would get it to this point for testing to begin with.

It appears, at first glance, that it needs assistance getting back to wherever it came from; likely Gigafactory Texas or potentially a Bay Area facility.

The Cybercab was also spotted in Buffalo, New York, last week, potentially undergoing cold-weather testing, but it doesn’t appear that’s where this incident took place.

It is important to remember that the Cybercab is currently undergoing some rigorous testing scenarios, which include range tests and routine public road operation. These things help Tesla assess any potential issue the vehicle could run into after it starts routine production and heads to customers, or for the Robotaxi platform operation.

This is not a one-off issue, either. Tesla had some instances with the Semi where it was seen broken down on the side of a highway three years ago. The all-electric Semi has gone on to be successful in its early pilot program, as companies like Frito-Lay and PepsiCo. have had very positive remarks.

The Cybercab’s future is bright, and it is important to note that no vehicle model has ever gone its full life without a breakdown. It happens, it’s a car.

Nevertheless, it is important to note that there has been no official word on what happened with this particular Cybercab unit, but it is crucial to remember that this is the pre-production testing phase, and these things are more constructive than anything.

Tesla analyst teases self-driving dominance in new note: ‘It’s not even close’

Tesla analyst Andrew Percoco of Morgan Stanley teased the company’s dominance in its self-driving initiative, stating that its lead over competitors is “not even close.”

Percoco recently overtook coverage of Tesla stock from Adam Jonas, who had covered the company at Morgan Stanley for years. Percoco is handling Tesla now that Jonas is covering embodied AI stocks and no longer automotive.

His first move after grabbing coverage was to adjust the price target from $410 to $425, as well as the rating from ‘Overweight’ to ‘Equal Weight.’

Percoco’s new note regarding Tesla highlights the company’s extensive lead in self-driving and autonomy projects, something that it has plenty of competition in, but has established its prowess over the past few years.

He writes:

“It’s not even close. Tesla continues to lead in autonomous driving, even as Nvidia rolls out new technology aimed at helping other automakers build driverless systems.”

Percoco’s main point regarding Tesla’s advantage is the company’s ability to collect large amounts of training data through its massive fleet, as millions of cars are driving throughout the world and gathering millions of miles of vehicle behavior on the road.

This is the main point that Percoco makes regarding Tesla’s lead in the entire autonomy sector: data is King, and Tesla has the most of it.

One big story that has hit the news over the past week is that of NVIDIA and its own self-driving suite, called Alpamayo. NVIDIA launched this open-source AI program last week, but it differs from Tesla’s in a significant fashion, especially from a hardware perspective, as it plans to use a combination of LiDAR, Radar, and Vision (Cameras) to operate.

Percoco said that NVIDIA’s announcement does not impact Morgan Stanley’s long-term opinions on Tesla and its strength or prowess in self-driving.

And, for what it’s worth, NVIDIA CEO Jensen Huang even said some remarkable things about Tesla following the launch of Alpamayo:

“I think the Tesla stack is the most advanced autonomous vehicle stack in the world. I’m fairly certain they were already using end-to-end AI. Whether their AI did reasoning or not is somewhat secondary to that first part.”

Percoco reiterated both the $425 price target and the ‘Equal Weight’ rating on Tesla shares.
