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.

SpaceX to become America’s Military data backbone for missiles, drones, and warfighters
The Space Force just handed SpaceX $2.29 billion to build the military’s space internet backbone.
The U.S. Space Force awarded SpaceX a $2.29 billion contract on May 26, 2026 to build the backbone of its Space Data Network, a satellite-based communications system designed to keep American military forces connected anywhere on Earth in real time. The contract is firm-fixed-price and requires SpaceX to deliver a fully operational prototype by the end of 2027.
In plain terms, the SDN Backbone is the plumbing behind the military’s space-based internet. It functions as a low Earth orbit satellite constellation providing robust, high-capacity, and low-latency data transport for the Joint Force, connecting sensors and weapons systems continuously, globally, and securely. Think of it as a private, hardened version of Starlink built specifically for battlefield communications, one that soldiers, ships, and aircraft can rely on even in contested environments where ground-based networks have been disrupted.
SpaceX is quietly becoming the U.S. Military’s only reliable rocket
The Space Force was direct about why SpaceX was selected. “The SDN Backbone leverages the best of commercial innovation and delivers a strong foundation for the SDN mission set — a huge benefit and enabler for our warfighters,” said USSF Col. Ryan Frazier.
“We aren’t trading speed for scale; we are demanding both. By using rapid prototyping and Other Transaction Authorities, we are ensuring our advanced solutions are integrated and delivered to the warfighter as fast as possible,” added USSF Lt. Col. Fry, SDN Backbone system program manager.
The SDN Backbone will work alongside the Space Development Agency’s Transport Layer, with the two systems forming a unified open architecture to provide critical data transport for current and future Department of War missions.
As Teslarati has reported, this is not SpaceX’s first Space Force contract of 2026. In April, the Space Force awarded SpaceX $178.5 million to launch missile tracking satellites, and SpaceX is already embedded in the Golden Dome missile defense software group. The $2.29 billion SDN Backbone award puts SpaceX at the center of how the American military communicates in space, a position with direct implications for its reported $1.75 trillion IPO valuation as the company heads toward a public offering as early as June 2026.
Tesla’s dedicated factory for building up to ten million Optimus units is officially under construction at Gigafactory Texas.
Drone footage released on May 27 by Giga Texas observer Joe Tegtmeyer captures the significant milestone of the first steel structure officially standing at Tesla’s new Optimus factory on the North Campus of the facility.
Phase two of land reclamation is advancing steadily, and the progress will let the new building extend nearly the full length of the main Giga Texas factory, potentially exceeding 4,000 feet, while measuring somewhere between 50 and 70 meters narrower. Extensive foundation work is proceeding as well.
Big news at the new Optimus 10m/y factory construction site today! The 1st steel structure has been erected & as expected the second phase of land reclamation is underway.
This will allow this new factory to grow to nearly the same length as the main Giga Texas factory,… pic.twitter.com/FidRLV6XpU

This facility forms a central element of Tesla’s broader North Campus expansion at Giga Texas. The project will add more than 5.2 million square feet of new industrial space. It sits alongside other advanced developments, including a Terafab for next-gen AI chips. The scale reflects Tesla’s commitment to transforming humanoid robotics into a core pillar of the company’s future.
Musk has said that Optimus will be the biggest product in the world on several occasions. He believes it will be Tesla’s biggest valuation contributor.
Tesla prepares to expand Giga Texas with new Optimus production plant
Tesla plans to build about 10 million robots at the site annually once it is completed, which would be about 27,000 units each day.
The Optimus plant at Giga Texas is part of Tesla’s phased strategy for Optimus manufacturing. In an effort to start production of the robot well before the Giga Texas plant is complete, Tesla ended production of the Model S and Model X vehicles, which were built in Fremont, California, to make way for initial Optimus manufacturing efforts.
Production there will start in either July or August of this year, and early units will support internal factory tasks while the team gathers real-world data to refine processes. The Gigafactory Texas facility will house a second-gen production line. It targets high-volume output starting in Summer 2027.
Musk has repeatedly described Optimus as potentially more valuable than Tesla’s entire vehicle business. Current versions are already completing minor tasks around various facilities, while Tesla continues to refine its abilities and add new features.
Tesla’s total investment could reach several billion dollars. Significant challenges lie ahead, including the creation of an entirely new manufacturing ecosystem, the refinement of AI systems for dependable autonomy, and the development of reliable supply chains for actuators, sensors, and other components.
Nevertheless, the visible progress at Giga Texas highlights Tesla’s capacity to translate ambitious concepts into physical reality.
Tesla’s Optimus factory stands as much more than a simple expansion project, as it is quite literally the second phase of what could potentially be the biggest product ever. With construction beginning, 2027 is poised to become a transformative year for Tesla, as it evolves even further from an electric vehicle leader into a pioneer of intelligent, general-purpose machines.
Tesla Vice President of Vehicle Engineering, Lars Moravy, recently revealed the company has thought about introducing a Plaid powertrain on the Model 3, but there could be some challenges involved.
On the Ride the Lightning podcast, Moravy revealed that he thinks about a Plaid Model 3 “all the time,” and it certainly has a place in Tesla’s potential lineup of future vehicles.
Now that the Plaid powertrain is technically defunct due to the newfound absence of the Model S and Model X, Tesla could find a way to reintroduce the lightning-quick trim level to its mass-market vehicles.
But there are going to be some challenges with it. Moravy said that the Model 3 Plaid would likely adopt the carbon-sleeved motors that the Model S Plaid had. However, packaging would be a major challenge, as Moravy said on the podcast, it would be a “tight engineering squeeze.”
It’s important to note that there are no active production plans for the Model 3 Plaid at this point, but it’s also worth noting that with the Model S and Model X Plaid no longer available, Tesla would likely be willing to introduce something that is even more white-knuckle than the Model 3 Performance, which already boasts a 2.9-second 0-60 MPH acceleration rate and a top speed of 163 MPH.
Of course, there is the Roadster, but we don’t know when that will exactly make it to market, and we know that, for sure, it will not be accessible to many.
Tesla unveils juicy new detail on the Roadster and hints at new unveil timeline
Tesla has prided itself in building some of the best cars out there, but they’re also interested in building cars that are simply fun to be in.
A Plaid Model 3 could truly push the limits and could end up being one of the best cars Tesla will ever build, especially if it can shave off at least half of a second from its 0-60 MPH time and increase its top speed slightly.
More than anything, the real changes will be in the ride and aerodynamics. Tesla improving things like the suspension, handling, and downforce will be the true trademarks of its Plaid powertrain; putting it in the Model 3 could be a great move for the company and for customers interested in high-end performance.
