SpaceX President Gwynne Shotwell expects BFR spaceship hop tests in late 2019

Speaking on a panel titled “Future of Space” at a 2018 conference for the Defense Advanced Research Projects Agency’s (DARPA) 60th anniversary, SpaceX COO and President Gwynne Shotwell reportedly confirmed that SpaceX is still targeting integrated BFR tests in 2019, in the form of hops with the next-gen rocket’s upper stage (known as BFS).

SpaceX has been gradually developing the BFR over the last two or so years, a rocket specifically intended to itself enable the sustainable, long-term colonization of Mars as quickly as practicable. The vast majority of that effort has been put funneled into the heart of the vehicle, a new propulsion system known as Raptor. Predicted years ago to be several times more powerful than the most modern iteration of Raptor, the rocket engine is targeting extreme efficiency both in its thrust to mass ratio and in the unique full-flow staged combustion cycle that will feed it propellant.

According to a major update from Elon Musk in late 2017 and early 2018, Raptor is expected to be roughly two times as powerful as the Block 5 Merlin 1D engines that power SpaceX’s Falcon 9 and Heavy rockets, while also being dramatically more efficient (judged from a measure known as Isp, or specific impulse) thanks to that aforementioned combustion cycle and the choice of liquid methane and oxygen as BFR’s propellant. In its sea level variant, SpaceX’s c. 2017 Raptor will generate 1700 kN (~380,000 lbf) of thrust – exactly 2X Merlin 1D’s current ~850 kN (~190,000 lbf) thrust rating. The vacuum variants of each rocket engine wind up with roughly 10% greater thrust.

SpaceX’s Mars city aspirations are functionally unachievable without an extraordinarily capable Raptor propulsion system ready to power BFR’s booster and spaceship. As such, initial hop tests (akin to the Grasshopper testing SpaceX used to flesh out Falcon 9 rocket recovery) can be expected to lean heavily towards a flight-test program for Raptor, perhaps mixed with some more serious structural experimentation and testing in later phases.

It’s also likely that initial Grasshopper-style testing of BFS will focus in part on the vehicle’s legs and general aerodynamic characteristics, absolutely critical if SpaceX hopes to land its first cargo and crew spaceships on unprepared Martian terrain – something that will have to be done to avoid major changes in early Mars mission strategy. Combined with some sort of autonomous radar (or perhaps a Tesla-assisted computer vision solution) and extensive prior planning (mapping out landing spots), those legs will need to be flexible enough to absorb any major terrain imbalances and prevent the rocket and its sensitive cargo from tipping over.

Equally importantly, hop testing – at least of the more extreme variety hinted at by CEO Elon Musk – will also allow SpaceX to test the aerodynamic behavior and control surfaces of the spaceship at points in Earth’s upper atmosphere that almost perfectly mirror the unusual atmospheric conditions on Mars, something that has already been exploited scientifically by both SpaceX and NASA during Falcon 9’s recovery development.

Per long-time SpaceNews correspondent Jeff Foust, Shotwell was paraphrased saying that she expected spaceship hop tests could begin as early as late 2019, admittedly a multi-month delay from “early 2019” comments made by Musk (and even Shotwell) earlier this year and late last year.

Tesla has created a clever solution to simplify and improve its Service. Tesla performs most of the services that are needed on its vehicles at its company-owned Service Centers.

However, service has been a weak point of the company, as some regions have fewer Service Centers than others. This can cause long wait times for Tesla owners in some parts of the country.

There are also instances where customers do not agree with what Tesla is saying about their vehicle. In fact, one instance that revealed this new change Tesla is making to its Service was precisely that.

One owner posted on X that his vehicle’s battery seal had failed after a recall was issued. Tesla insurance and Tesla Service both did not assist, and it took CEO Elon Musk stepping in to get the issue resolved:

Another owner suggested there should be a more streamlined communications process between the customer and the Service Center, a solution that has been missing.

Raj Jegannathan, a Vice President of IT/AI-Infra, Apps, Infosec, and Vehicle Service Operations, revealed that Tesla has started a small pilot program at a few service locations to combat this issue.

Jegannathan said that Tesla has started to share local and regional leader contact information so customers have the ability to reach out when they have complaints or disagree with warranty claims, changes in estimates, or initial diagnostics.

It is available in a handful of locations already, and Jegannathan said that once abuse guardrails are built, this will expand to all locations:

This would be a major improvement in the Service portion of Tesla’s business. There are common disagreements between Service and customers, specifically when Service’s suggestions don’t align with the customer’s beliefs.

When it comes to things like a warranty claim, these issues are not really up for interpretation. Instead, the repairs should be made. If there is a misunderstanding on Service’s side, a simple message from the customer could have resolved the issue. That’s basically what happened here.

Tesla gets its best analysis from Morgan Stanley as ‘it’s all about to change’

He maintained its ‘Overweight’ rating and the $410 price target Morgan Stanley had on the stock.

Tesla has gotten perhaps its best analysis from Morgan Stanley in quite some time, as the Wall Street firm claims that “it’s all about to change.”

That phrase could be used for both the company’s status and the world in general.

Analyst Adam Jonas said in a new note on Thursday to investors that Tesla could be one of the major winners in terms of the global transition from what it is now to what it will be.

He describes the global shift that will occur over the next few years:

“Have you interacted with a robot today? Have you even seen a robot today? No? Well, take a mental picture because it’s all about to change. When we meet someone who has never been in a Waymo or a Tesla Cybercab (which is most people), we frequently see a wince and a response such as ‘I’m not sure I’d feel comfortable getting in a car without a driver.’ We imagine going back in time to 1903 and asking people if they’d feel comfortable in an airplane.’”

The same technological revolutions that have occurred over the past 150 years will continue to occur again and again. We are on the verge of another, Jonas believes, as companies like Tesla are working on artificial intelligence tech, which includes changing the way we look at things like transportation and labor.

Jonas includes an interesting tidbit in his note about how humanoid robots could change wages, and how it could work into the advantage of Tesla, especially as it is developing its own Optimus robot:

“We estimate 1 humanoid robot at $5/hour can do the work of 2 humans at $25/hour, generating an NPV of approximately $200k/humanoid. 1 robot shaped car can potentially drive down cost/mile of a ride share vehicle to <$0.20 mile (1/10th human-driven ride-share).”

Jonas sees Tesla as a key player in how AI will impact things like manufacturing and various automotive industries, and he believes there is long-term potential for AI, robomobility, and even autonomous eVTOL platforms.

Tesla is expanding its Robotaxi program in Austin, Texas, as several people have received invitations to participate and take rides.

Tesla first launched the Robotaxi platform on June 22. It invited a handful of people to participate in the first-ever public rides. We were lucky enough to get an invitation, and our permissions have been expanded in the Bay Area pilot program as well.

The group was small and consisted of big names in the Tesla community. It expanded and is continuing to offer these exclusive invitations to notable members of the Tesla community.

There have been fewer than five subsequent invitations after the first group’s were sent in late June:

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.

Eventually, the Robotaxi platform will not require an invite, and it will operate without geofences. Musk believes Tesla can get there within three or six months, and plans to have at least half of the U.S. population with access to a Robotaxi by the end of the year:

“I think we will probably have autonomous ride-hailing in probably half the population of the U.S. by the end of the year. That’s at least our goal, subject to regulatory approvals. I think we will technically be able to do it. Assuming we have regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year.”

Tesla plans to have regulatory approval in Nevada, Arizona, and Florida sooner than in other states.
