NASA’s SLS Moon rocket is almost ready for its first trip to the launch pad
NASA says its first complete Space Launch System (SLS) rocket is less than a week away from its first rollout and the start of its first East Coast ‘wet dress rehearsal’.
Teams have begun retracting work platforms surrounding the fully stacked rocket, slowly revealing the launch vehicle assigned to Artemis 1 – a much anticipated and extensively delayed uncrewed test flight of the SLS rocket and Orion spacecraft. Since April 2021, SLS and Orion have been slowly but surely assembled within the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Cape Canaveral, Florida.
Preparing the rocket for the launch pad has required an arduous and complex series of tests meant to ensure that the vehicle is ready for the stresses it will experience and the operations it will perform before and during launch. The rollout is expected to begin around 5 pm EST (22:00 UTC) on Thursday, March 17th and, if all goes well, it should take the giant crawler tasked with carrying the rocket and ‘mobile launch platform’ about 12 hours to carry them to Launch Complex 39B (LC-39B or Pad 39B). The first hour of the rollout will extricate the rocket and its mobile launch tower from the VAB, followed by an 11-hour journey to the pad.
NASA says SLS will spend around one month at Pad 39B, during which it will undergo expensive testing required to ensure its launch readiness. After two weeks on the pad, SLS will have its tanks filled with liquid hydrogen (LH2) and liquid oxygen (LOx) propellant and run through a simulated countdown in a process known as a wet dress rehearsal (WDR). Representatives of the Artemis-1 mission indicate “the countdown will end at about [T-minus 9 seconds], which is just moments before the rocket’s four RS-25 engines would ignite [before] an actual launch.” By allowing the countdown to run so low, test teams are able to check all interfaces (aside from the rocket’s RS-25 engines) that must be carefully coordinated during launch.
Once the wet-dress is complete, SLS will be rolled back into the VAB for final launch preparations, including the identification and repair of any issues found during wet-dress, final Orion spacecraft work, and flight software updates. After SLS’ return to the VAB, NASA expects that final work to take one month to complete. However, NASA officials admit that there is still a lot of work to be done to SLS before launch, and almost every aspect of the space agency’s work on the rocket over the last two and a half years has run into extensive delays.
An official launch date has not been chosen by NASA, as delays continue to make setting a specific date impractical. Tom Whitmeyer, NASA deputy associate administrator for exploration systems development, has indicated that a launch in April is no longer feasible. “We’re still evaluating the tail end of the May window,” he said, which runs from May 7 to 21. Future launch windows, governed by orbital mechanics and other mission constraints like ensuring that Orion is recovered in daylight, are June 6 to 16 and June 29 to July 12, with a “cutout” of July 2 to 4, when a launch would not be possible.
The Artemis-1 mission will be the first uncrewed integrated flight test of NASA’s Orion spacecraft and Space Launch System rocket. The SLS rocket is designed for missions beyond low-Earth orbit carrying crew or cargo to the Moon and beyond. At liftoff, it will weigh approximately six million pounds (~2700 tons) and produce around 8.8 million pounds (~4000 tons) of thrust.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
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.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

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.
