SpaceX has been granted an additional $40.7 million in funding by the U.S. Air Force for development of the company’s Raptor engine.

According to a U.S. Department of Defense contract published on October 19, 2017 on defense.gov, the new funding will go towards development of a new liquid oxygen and liquid methane engine for the department’s Evolved Expendable Launch Vehicle (EELV) program. Each Raptor engine is expected to have three times the thrust of SpaceX’s Merlin 1D engine that’s currently used in the Falcon 9. The heavy lift-capable engine will support the launch of heavier payloads including large military satellites into orbit, but also serve as the foundation for SpaceX’s Interplanetary Transport System, or more recently referred to as BFR.

The Department of Defense issued the following contract:

Space Exploration Technologies Corp., Hawthorne, California, has been awarded a $40,766,512 modification (P00007) for the development of the Raptor rocket propulsion system prototype for the Evolved Expendable Launch Vehicle program.  Work will be performed at NASA Stennis Space Center, Mississippi; Hawthorne, California; McGregor, Texas; and Los Angeles Air Force Base, California; and is expected to be complete by April 30, 2018.  Fiscal 2017 research, development, test and evaluation funds in the amount of $40,766,512 are being obligated at the time of award.  The Launch Systems Enterprise Directorate, Space and Missile Systems Center, Los Angeles AFB, California, is the contracting activity (FA8811-16-9-0001).

It’s not clear how the Air Force will utilize the powerful Raptor engines after its completion which is expected to take place by the end of April 2018, but we do know that development will take place in various locations, including SpaceX’s headquarters in Hawthorne, California; NASA’s Stennis Space Center in south Mississippi; and the Los Angeles Air Force Base, home to its Missile Systems Center.

The powerful methane-oxygen Raptor engine is intended to be the workhorse for any larger launch vehicle. SpaceX has conducted several dozen successful hot fires at the company’s McGregor, Texas testing facilities. Tests ranged from just a few seconds to 100 seconds in duration, with the only limiting factor to test duration being the size of the propellant tank for fuel.

Serial tech entrepreneur and SpaceX CEO Elon Musk recently spoke about Raptor engine development in his Mars-focused address at the International Astronautical Congress (IAC) in Australia.

“We already have now 1,200 seconds of firing across 42 main engine tests,” said Musk. “We’ve fired it for 100 seconds. It could fire for much longer than 100 seconds. That’s just the size of the test tanks.”

Musk also provided insight on why SpaceX engineers decided to reduce the originally intended size and thrust capabilities of the Raptor engine. Musk explained to fans during a recent Reddit “Ask me anything” that the SpaceX team simply “chickened out”, due to a variety of reasons.

Elon Musk: Tesla autonomous driving might spread faster than any tech

The CEO noted that “hardware foundations have been laid for such a long time.”

Elon Musk has shared one of his most optimistic forecasts for Tesla’s self-driving rollout yet. As per the CEO, Tesla’s self-driving system could see the fastest technological adoption in history, thanks to the fleet’s capability to gain autonomous capabilities through a software update.

The CEO shared his forecast in a post on social media platform X.

Tesla’s aims to scale autonomy

Musk’s comment came as a response to industry watcher Sawyer Merritt, who posted a comparison between the geofence of Tesla’s Robotaxi network and Waymo’s service area. As can be seen in the graphic, Tesla’s Austin geofence has gotten noticeably larger compared to Waymo’s service area. 

In his response, Musk stated that “Tesla autonomous driving might spread faster than any technology ever.” He also stated that “hardware foundations have been laid for such a long time,” as a software update could unlock full autonomy “for millions of pre-existing cars in a short period of time.”

Musk’s comment bodes well for Tesla’s Robotaxi ambitions, which seem to be finally in reach with the deployment of Unsupervised FSD in vehicle factories, as well as Austin and the Bay Area. For now, however, Tesla’s Austin Robotaxis and Bay Area ride-hailing vehicles are still operated with a safety monitor in the driver’s seat.

Tesla’s latest Austin expansion

Tesla recently expanded its Austin Robotaxi service area this week to 243 square miles, its largest yet and nearly triple the coverage from two months ago. The move outpaces Waymo’s local service footprint, which remains at around 90 square miles.

The expansion marks Tesla’s second major Austin update since August and emphasizes its push to dominate the autonomous ride-hailing landscape. With both Tesla and Waymo racing to prove scale and reliability, Musk’s confidence suggests the real contest may be about who can move fastest once the tech flips on across Tesla’s fleet. Once that happens, Tesla would effectively be able to win the self-driving race.

Tesla sends clear message to Waymo with latest Austin Robotaxi move

It is the first expansion Tesla has made in Austin since the one on August 26. The company still operates in the Bay Area of California as well, referring to that program specifically as a “ride-hailing service.”

Tesla has sent a clear message to Waymo with its latest move to its Robotaxi program in Austin, Texas.

Tesla and Waymo are the two true leaders in autonomous ride-hailing to an extent. Tesla has what many believe is a lot of potential due to its prowess with the Supervised Full Self-Driving suite. It is also operating a driverless Robotaxi service in Austin with a “Safety Monitor” that sits in the passenger’s seat.

Tesla explains why Robotaxis now have safety monitors in the driver’s seat

The two companies have been competing heavily in the market since they both launched driverless ride-hailing services in Austin this year: Waymo’s in March and Tesla’s in June.

One of the main drivers in the competition between the two is service area size, or the geofence in which the cars will operate without a driver. In August, the two were tied with a service area of about 90 square miles (233.099 sq. km).

Tesla then expanded to about 170 square miles (440.298 sq. km) on August 26, dwarfing Waymo’s service area and expanding to freeways. Tesla’s freeway operation of the Robotaxi suite requires the Safety Monitor to be in the driver’s seat for safety reasons.

On Tuesday evening, Tesla made another move that sent a clear message to Waymo, as it expanded once again, this time to 243 square miles (629.367 sq. km).

This is according to Robotracker:

It is the first expansion Tesla has made in Austin since the one on August 26. The company still operates in the Bay Area of California as well, referring to that program specifically as a “ride-hailing service.”

Yesterday, it expanded that service to the San Jose Mineta International Airport, something it has been working on for several months.

Waymo has its own set of distinct advantages over Tesla as well, as it operates in more cities and states than the EV maker. Waymo currently has its autonomous vehicle services in Phoenix, Arizona, San Francisco, Los Angeles, Austin, and Atlanta, Georgia.

Tesla plans to have half of the U.S. population with access to the Robotaxi platform by the end of the year.

Tesla exec reveals shock development with Cybercab

“If we have to have a steering wheel, it can have a steering wheel and pedals.”

Tesla is planning to launch the Cybercab in the second quarter of next year, and it is designed to be fully autonomous, so much so that the company is planning to build it without a steering wheel or pedals.

However, a Tesla executive said today that the company could ditch that idea altogether in what would be a major shift from the plans the company, and especially its CEO Elon Musk, have announced for the Cybercab.

Earlier today, Robyn Denholm, the company’s Chair for the Board of Directors, revealed that Tesla would potentially switch up its plans for the Cybercab based on potential regulatory requirements.

Currently, even autonomous vehicles that operate for companies like Tesla and Waymo are required to have steering wheels and pedals. From a regulatory perspective, this could halt the plans Tesla has for Cybercab.

Denholm said in an interview with Bloomberg:

“If we have to have a steering wheel, it can have a steering wheel and pedals.”

Interestingly, Musk and Tesla have not veered away from the idea that the vehicle will be without these operational must-haves.

Since the vehicle was revealed last October at the We, Robot event in Los Angeles, Tesla has maintained that the car would be built without a steering wheel or pedals, and would equip two seats, which is what is statistically most popular in ride-sharing, as the vast majority of rides have only one or two passengers.

Musk doubled down on the plans for Cybercab as recently as last week, when he said:

“That’s really a vehicle that’s optimized for full autonomy. It, in fact, does not have a steering wheel or pedals and is really an enduring optimization on minimizing cost per mile for fully considered cost per mile of operation. For our other vehicles, they still have a little bit of the horse carriage thing going on where, obviously, if you’ve got steering wheels and pedals and you’re designing a car that people might want to go very direct past acceleration and tight cornering, like high-performance cars, then you’re going to design a different car than one that is optimized for a comfortable ride and doesn’t expect to go past sort of 85 or 90 miles an hour.”

Cybercab is fully conceptualized as a vehicle that has zero need for pedals or a steering wheel because it is aimed toward being fully reliant on a Level 5 autonomous platform.

Tesla is ramping its hiring for Cybercab vehicle manufacturing roles

Regulators could get in the way of this, however, and although the car could drive itself and be a great solution for ride-hailing, it might need to have these controls to hit the road in the future.
