SpaceX has completed a Falcon 9 static fire test ahead of the company’s first launch of 2019, kicking off what is looking to be a truly jam-packed year for Falcon 9 and BFR. Most important, of course, is SpaceX’s primary business and main sources of revenue – safely and reliably launching customer satellites, payloads, and – soon – astronauts into orbit.

Previously tasked with launching heavy communications satellite Telstar 18V in September 2018, Falcon 9 B1049 is now set to launch an arguably historic mission for both SpaceX and customer Iridium, the eighth and final contracted launch of the upgraded Iridium NEXT satellite communications constellation.

Struck all the way back in June 2010, Iridium’s decision to award the full NEXT constellation launch contract to SpaceX less than two weeks after Falcon 9’s first and only launch may well be the greatest calculated leap of faith in the history of commercial spaceflight. SpaceX did admittedly offer an unbeatable price ($492M for eight launches, $61.5M per launch) that may have allowed Iridium to afford a new constellation in the first place, but the risk Iridium took was truly immense at the time.

Originally launched between 1997 and 1998, the first Iridium constellation became and still remains the only satellite communications constellation in history to offer global and persistent coverage anywhere on Earth, allowing those with Iridium devices to guarantee connectivity no matter where they are. To some extent, the original constellation has become a subtle but omnipresent backbone of a huge variety of ventures, companies, and services, ranging from marine vessel tracking and emergency response to the go-to solution for those heading far off the beaten path. As just one small example, SpaceX’s large fleet of sea-going vessels and its cross-country transport infrastructure both rely on Iridium for streamlined company-wide movement tracking, making life considerably easier for logistics and planning teams.

Iridium’s decision to use SpaceX for its NEXT constellation likely also gave SpaceX a massive stature boost, taking it from the company with just a handful of commercial contracts that had failed three of its last five launches to the company that secured what was at the time the largest single commercial launch contract in history. Alongside NASA’s Commercial Orbital Transport Services (COTS) and Resupply Services (CRS) commitments (~14 launches as of 2010), Iridium NEXT raised SpaceX’s commercial manifest from perhaps 2 missions to ~10 while also taking the value of those contracts from an almost negligible sum to well over half a billion dollars.

Although SpaceX and Iridium originally planned for launches to take place over a roughly 24-month period stretch from 2015 to 2017, unplanned technical delays and a duo of catastrophic Falcon 9 failures (CRS-7 and Amos-6) in 2015 and 2016 ultimately pushed Iridium NEXT’s launch debut back several years. Despite those immense hurdles and a range of smaller issues, SpaceX and Iridium were finally able to begin launching satellites in January 2017 and have continued to consistently do so every 3-4 months since then. Aside from one partial NASA rideshare mission that featured five NEXT satellites in May 2018, all seven launches have placed ten NEXT satellites (weighing approx. 10,000 kg or 22,000 lb total) in a variety of low polar orbits without a single known hitch.

Falcon 9 enters the era of reusability

Closely following SES, NASA, and SSL (BulgariaSat), Iridium also became the fourth commercial entity to launch on a flight-proven Falcon 9 rocket for the launch vehicle’s fourth flight-proven mission ever. Iridium-8 will become the fourth constellation launch to fly aboard a sooty Falcon 9 rocket, meaning that a full 50% of the next-gen satellites will have launched on reused rockets, easily one of the coolest bragging rights ever. Currently standing at 65 NEXT satellites in orbit and rapidly nearing operational status, Falcon 9 B1049 and a fresh upper stage will (fingers crossed) place the last ten satellites in orbit to complete the constellation’s last plane and seal the last gap in its perfect global coverage.

Although NEXT would have been valuable for the sole reason that its predecessor satellites are now 5-10 years past their designed lifespans, NEXT will also serve to dramatically increase Iridium’s overall bandwidth, slash concurrent user bottlenecks, and provide a platform for new services like Aireon, which hopes to become the first operator of a truly commercial aircraft tracking service with global satellite-based coverage.

All things considered, it will be hugely bittersweet to watch Iridium and SpaceX’s direct relationship come to a close with the launch of Iridium-8. Aside from nine additional on-orbit spares once all 75 are launched, Iridium will also have a complement of six more spares that will be kept in storage on the ground until they are required in orbit. If or when those times come, SpaceX will be able to compete with other launch providers for the opportunity to carry maybe one or two Iridium satellites – likely as rideshare payloads – into orbit sometime in the future.

In the meantime, stay tuned for Iridium-8’s official launch time and date, likely to be announced by SpaceX sometime within the next 24-48 hours.

Tesla’s flying Roadster just revealed something bigger than the car

Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.

The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.

Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.

The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.

The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.


Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.

The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.
