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).
Shotwell: think we’ll be “hopping” the second stage of BFR (the BFS) late next year. #DARPA60

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 extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.

Tesla’s reason for Starlink integration on Cybercab might surprise you, as the company’s Head of AI, Ashok Elluswamy, finally shed some light on the reason they are putting a satellite internet terminal on its ride-hailing-geared vehicle.
On Monday, Tesla officially confirmed that it would integrate Starlink V5 terminals into Cybercab vehicles, something many Tesla fans had figured the company would do, as the vehicle is primarily geared toward giving rides without any passenger intervention.

The ability to access the internet would allow riders to work or play in the car with their devices. It seemed like a more-than-reasonable feature to add to the Cybercab, which made its way off the production lines for the first time earlier this year.

However, the move is not for the rider, as Elluswamy confirmed on Monday night. Instead, it’s actually for Tesla to be able to have a constant connection to the cars in the Robotaxi fleet so it can troubleshoot issues, contact riders, or resolve other issues.
Elluswamy said:
“It is still not required for safe operation of the vehicle. Connectivity is primarily meant for navigation, customer service and, in general, fleet management.”

Many initially assumed the option of constant connectivity would be enabled on the Cybercab for passenger entertainment or work. With the Cybercab, passengers won’t be doing anything but enjoying the ride, so it seemed more than logical that they would be hanging out with Starlink internet access as an amenity.
However, Tesla’s primary concern with Robotaxi is safety, and nailing these first unsupervised rides is a crucial step to setting a good narrative on how effective driverless transportation can be.
Being able to get in touch with passengers or a vehicle if something is wrong is a crucial part of the overall experience, and preventative measures are being taken by Tesla to ensure a smooth process, even in the worst-case.
