SpaceX closes in on Falcon 9 reliability milestone after flawless Monday launch [photos]
SpaceX’s workhorse Falcon 9 rocket has completed its thirteenth launch of 2019, leaving the vehicle just one mission away from a major reliability milestone.
At 7:10 pm ET, December 16th (00:10 UTC, Dec 17), Falcon 9 booster B1056, a new upper stage, and the nearly 7-metric ton (15,500 lb) Kacific-1/JCSAT-18 communications satellite lifted off from SpaceX’s Cape Canaveral LC-40 launch pad. As has more or less become the norm, Falcon 9 sailed through prelaunch preparations, payload integration, and launch with zero notable issues and lifted off at the precise start of a ~90-minute window.
Around nine minutes after launch and 30 seconds after the second stage reached orbit, Falcon 9 B1056 successfully landed aboard drone ship Of Course I Still Love You (OCISLY), completing the booster’s third launch and landing in seven months. 27 minutes after launch, Falcon 9’s second stage reignited and burned for more than 50 seconds, raising one end of its orbit by more than 20,000 km (12,500 mi). Five minutes later, Falcon 9 officially completed its mission by gently releasing Kacific-1/JCSAT-18 from the second stage, where the satellite shortly reoriented itself, deployed ~40-meter (~125 ft) long solar ‘wings’, and began verifying its systems’ health.
Aside from another successful and issue-free launch under the Falcon family’s belt, the Kacific-1 mission is significant for another major reason: it’s Falcon 9’s 49th consecutively-successful launch since January 2017. Falcon 9’s last catastrophic failure occurred on September 1st, 2016 when the rocket’s upper stage violently exploded, destroying the rest of the rocket and its Amos-6 satellite payload.
SpaceX took approximately four months to determine the root cause of that failure and modify hardware and procedures accordingly before returning to flight with the first Iridium NEXT launch on January 14th, 2017. In the three years (35 months) since then, Falcon 9 has successfully launched a total of 49 times in a row without even a partial failure. After one additional launch success, Falcon 9 will have flown 50 consecutively-successful missions, a symbolic but still exceptional sign of the rocket’s excellent reliability. That 50th launch attempt could come as early as December 30th in the form of SpaceX’s third 60-satellite Starlink mission, known as Starlink-2.
Technically speaking, if Falcon Heavy is included, SpaceX has already completed 52 consecutively-successful orbital launches without a single failure (or partial failure), the only company or space agency in the world that can currently claim that feat. Although both Arianespace and ULA are infamous for whitewashing the partial failures of their launch vehicles, Ariane 5 unfortunately suffered a partial failure in January 2018, while ULA’s Atlas V and Delta IV suffered their own partial failures in 2007 and 2004, respectively. Atlas V experienced another in-flight anomaly in 2016, although it was not technically classified as a partial failure.
This means that Ariane 5, Delta IV, and Atlas V – still some of the most reliable launch vehicles ever built – have technically only performed 9, 36, and 70 (or 18) consecutively-successful launches since their most recent partial failure (or in-flight anomaly). In other words, if measured in terms of uninterrupted consecutive launch successes, SpaceX’s Falcon 9 is either the most reliable or the second most reliable launch vehicle currently in operation.
Perhaps even more impressive is the fact that SpaceX has pulled off that feat of reliability in less than three years, unequivocally making Falcon 9 the best all-purpose launch vehicle in the world in terms of its combined reliability and flight frequency – the latter thanks in large part to the rocket’s exceptionally competitive pricing.
As of now, SpaceX has at least two or three-dozen launches nominally planned for 2020 and if all of those launches are successfully completed, Falcon 9 will almost certainly become the world’s most reliable operational launch vehicle by any measure.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
