SpaceX has completed its third rocket launch of 2020 and the most recent booster to launch safely returned to Port Canaveral on Saturday after an exceptionally hard drone ship landing.

Falcon 9 booster (first stage) B1051 lifted off for the third time on January 29th, following up two prior orbital-class missions by placing SpaceX’s fourth batch of 60 Starlink satellites into low Earth orbit (LEO). B1051 debuted on March 2nd, 2019 when it became the first Falcon 9 rocket to launch SpaceX’s next-generation Crew Dragon spacecraft, successfully sending the vehicle on its way to what would end up being a flawless rendezvous with the International Space Station (ISS). Less than four months later, B1051 completed its second mission, this time lifting off from SpaceX’s Vandenberg Air Force Base (VAFB), California facilities before landing in zero-visibility fog conditions just a thousand feet from the pad.

Compared to some of the higher-energy geostationary (high orbit) launches SpaceX often performs, B1051’s two prior launches allowed for relatively gentle reentries and landings. On January 29th, 2020, after sending SpaceX’s 3rd batch of upgraded Starlink v1.0 satellites (Starlink V1 L3) on their way to space, the Falcon 9 booster experienced the hardest successful landing seen after a SpaceX launch in quite some time.

With Starlink V1 L3 complete, SpaceX has officially launched an incredible 120 satellites weighing some 32 metric tons (70,500 lb) in a single month – 22 days, to be precise. If everything goes as planned, those two monthly Starlink launches should become SpaceX’s average over the rest of 2020, necessary to satisfy the company’s goal of completing 20-24 Starlink launches this year alone. If SpaceX replicates its January successes this month, the company’s Starlink constellation – already ~230 satellites strong – may even be ready to start serving internet to customers in the northern US and Canada as early as March 2020, less than two months from now.

Meanwhile, the mission marked SpaceX’s second Falcon 9 landing and recovery of the new year, as well as the sixth time an orbital-class SpaceX booster has completed three launches. SpaceX continues to push the envelope of reusable rocketry ever since it debuted Falcon 9’s Block 5 upgrade in May 2018.

Designed to enable no less than 10 launches per booster with minimal refurbishment in between, SpaceX’s Block 5 reusability milestones have gotten much closer together ever since the company began dedicated Starlink launches, reusing a payload fairing for the first time and launching two Falcon 9 boosters for the fourth time in just the last two and a half months. In fact, SpaceX already has plans to launch Falcon 9 booster B1048 for the fifth time – another major reusability first – as early as the next 4-5 weeks.

Hard landing; tough rocket

Starlink V1 L3’s launch followed a trajectory almost exactly identical to the two V1 missions that preceded it in November 2019 and January 2020 and Falcon 9 B1051 ignited its central Merlin 1D engine for the last time around eight minutes after liftoff. Twenty seconds or so later, the Falcon 9 booster rapidly shut down its landing engine, visibly falling several feet onto the deck of drone ship Of Course I Still Love You (OCISLY).

Taken from the same vantage point in March 2019 and February 2020, these two photos of Falcon 9 B1051 emphasize just how hard the booster landed after its third launch. (Richard Angle)

The results of that unintentionally hard landing are extremely apparent in photos taken of the same booster after its first (March 2019) and third (Jan 2020) landings on drone ship OCISLY, compared above. Taken from almost identical perspectives as the drone ship passed through the mouth of Port Canaveral, the difference in the booster’s height and stance are hard to miss, with B1051’s engine bells and the black ‘belt’ of its heat-shielded engine section clearly sitting several feet lower after Starlink V1 L3.

While subtle, the most important difference is near the tips of each visible landing leg’s telescoping boom, visible in the form of a final, smaller cylinder on the left (earlier) image. On the right, that cylinder has effectively disappeared. This is actually an intentional feature of Falcon 9’s landing leg design: known as a ‘crush core’, the tip of each leg boom holds a roughly 1m (3ft) long cylinder of aluminum honeycomb, optimized to lose structural integrity (crush) only after a specific amount of force is applied. In essence, those crush cores serve as dead-simple, single-use shock absorbers that can be reused as long as a given booster’s landing is gentle enough.

B1051’s third landing was definitely not gentle enough, but it appears that the booster’s rough fall onto the drone ship’s deck was just within the safety margins those crush cores provide. Why B1051 fell onto the deck is unclear, potentially caused by the drone being at the bottom of a swell or a last-second anomaly with the booster’s landing engine. Thankfully, regardless of the cause of the anomaly, B1051’s crush cores can be quite easily replaced, meaning that the booster can remain operational as long as its hard landing didn’t cause any less-visible damage or stress elsewhere on the rocket.

In short, SpaceX smart design decisions very likely allowed a part worth just a few thousand dollars to save a Falcon 9 booster worth tens of millions of dollars from the scrap heap. With a little luck, B1051 should have at least several more launches in its future before entering retirement.

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.

SpaceX is opening up its internet service, Starlink, to those impacted by Hurricane Melissa, as it made landfall in Jamaica and the Bahamas as a Category 5 storm.

Hurricane Melissa is expected to reach wind speeds of over 165 MPH over the next few days as it extends out into the Atlantic Ocean by Thursday and Friday.

Citizens in Jamaica and the Bahamas have been preparing for the storm for the past week, getting necessary goods together and preparing for the massive storm to arrive. It finally did yesterday, and the first images and video of the storm are showing that it could destroy many parts of both countries.

Starlink is now being opened up for free until the end of November for those impacted by the storm in Jamaica and the Bahamas, SpaceX announced today:

It is a move similar to the one the company made last year as Hurricane Helene made its way through the United States, destroying homes and property across the East Coast. SpaceX offered free service for those impacted by the destruction caused by the storm.

The free Starlink service was available until the end of 2024.

Elon Musk’s companies have also made similar moves to help out those who are impacted by natural disasters. Tesla has offered Free Supercharging in the past, most notably during the California wildfires.

Tesla and SpaceX’s LA fire relief efforts: Cybertrucks, free Starlink and more

One major advantage of Starlink is that it is available for use in situations like this one, where power might be required to operate things like a modem and router.

Internet access is a crucial part of survival in these situations, especially as it can be the last leg some stand on to get in touch with emergency services or loved ones.
