SpaceX rapidly tests, ships Falcon 9 second stage for next NASA astronaut launch

Published

on

SpaceX has shipped, tested, and delivered the new Falcon 9 upper stage tasked with carrying the company’s next Crew Dragon astronauts to orbit as early as October 30th.

Offering rare insight into the kind of timelines and margins SpaceX operates on for even its most important missions, a Falcon upper stage bearing NASA’s ‘worm’ logo and ‘meatball’ insignia was spotted by a local resident and photographer on October 2nd. Thus far, the only SpaceX rockets that have flown with NASA iconography are those supporting Crew Dragon launches, making them a dead giveaway for Crew Dragon launch hardware.

After Demo-2, SpaceX’s May 2020 astronaut launch debut, the company moved those decals from Falcon 9’s booster – liable to fly any number of non-NASA missions later in life – to each NASA crew mission’s expendable Falcon second stage (S2). Since then, Crew-1 (November 2020) and Crew-2 (April 2021) have both launched with NASA logos on their second stages and Crew-3 now looks set to continue that tradition.

A new Falcon upper stage bearing NASA insignias was first spotted in Texas on October 2nd.
Less than two weeks later, that same upper stage may have arrived in Cape Canaveral, Florida.

Thanks to the watchful eye of local resident turned SpaceX fan Reagan Beck, it was actually possible to identify Crew-3’s Falcon 9 upper stage as soon as it was spotted at the company’s McGregor, TX development and testing facilities on October 2nd. While there was technically a tiny chance that it could be for one of several upcoming NASA spacecraft launches or even for Crew Dragon’s April 2022 Crew-4 mission, the likeliest destination by far for the NASA-branded Falcon S2 was Crew-3.

Due partially to the fact that Falcon booster qualification testing typically takes McGregor at least two or so weeks but mainly to the seemingly razor-thin schedule margins it would imply, there was some understandable skepticism that the upper stage was bound to launch Crew-3 just four weeks after it was first spotted. Moreso, Crew Dragon typically rolls out to the launch pad on Falcon 9 at least 5-7 days before launch to allow extra time for an integrated static fire, final checkouts, and a ‘dry dress’ practice runs for each mission’s crew.

Further, even after completing static fire qualification testing in McGregor, Crew-3’s Falcon stage would still need to be packaged up, transported more than a thousand miles by road, carefully unpackaged at a SpaceX launch site or hangar, outfitted with a Merlin Vacuum nozzle extension, installed on the mission’s Falcon 9 booster, and mated to Crew Dragon itself before that pad rollout can occur. In other words, rather than Crew-3’s exact October 30th launch date, the mission’s upper stage would likely need to arrive at SpaceX’s Kennedy Space Center (KSC) Pad 39A launch facilities at least 9-10 days before launch.

Realistically, that means that from the moment the NASA-branded upper stage first spotted on a McGregor test stand, it had maybe two weeks to complete qualification testing and ship out to Pad 39A. With practically no context, that seemed like a stretch at the time – particularly for a single-engine Falcon second stage explicitly tasked with safely delivering four astronauts to orbit. In reality, McGregor’s Falcon S2 testing is apparently far faster than booster testing and the presumed Crew-3 stage seemingly passed qualification testing and vacated the test stand less than five days after it was installed.

In theory, that left the McGregor team about a week to complete post-test inspections, clean the interior of its propellant tanks, and prepare the stage for the last leg of its journey to Florida. SpaceX seemingly managed that without issue and a new Falcon upper stage potentially meant for Crew-3 was spotted in Florida just a few miles away from a SpaceX launch site on October 14th.

However, per additional photos and reports from Reagan, McGregor’s second stage test team has been incredibly busy over the last month or so. Prior to the Crew-3 stage’s arrival, another second stage completed qualification testing between September 21st and 28th. Crew-3’s S2 was installed on October 2nd and removed by the 7th. Wasting no time, another second stage was installed on the same stand on October 10th and apparently completed testing by the 13th – equivalent to a new upper stage qualified every week. Even if the Falcon stage that arrived at Cape Canaveral on October 14th isn’t Crew-3’s, then, Crew-3’s can’t be far behind.

Ultimately, SpaceX appears to be testing and shipping one of two integral Falcon 9 stages for a crucial, schedule-sensitive NASA astronaut launch with schedule margins measured in hours or single-digit days. That’s a far cry from competitors Arianespace and ULA and even NASA itself, which generally deliver flight hardware months in advance. Eleven years since Falcon 9’s launch debut, every Falcon second stage that has made it through stage separation – 127 of 127 – has successfully ignited its Merlin Vacuum engine one or several times and delivered its payload(s) to the correct orbit(s). Well over half of those successful launches were completed in the last three and a half years – and with the same Falcon 9 upper stage variant now routinely tasked with carrying astronauts to orbit.

In other words, delivering a NASA Crew mission’s Falcon second stage less than two weeks before the assembled rocket is scheduled to roll out to the launch pad may seem a tad reckless, it’s more likely that it’s evidence of SpaceX’s second stage build/test teams and facilities operating as an incredibly reliable, well-oiled machine.

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.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store

Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.

Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.

The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.

The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.

The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.

The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.

Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.

So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
