NASA’s SLS Moon rocket is almost ready for its first trip to the launch pad

After almost a year of assembly, NASA may finally be ready to roll its SLS rocket to the launch pad for the first time - albeit not to launch. (NASA)

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.

Tesla Optimus is learning martial arts in new video teasing capabilities

For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet.

Tesla Optimus is learning martial arts, a new video released by CEO Elon Musk shows, a crazy development and advancement in the robotics project the company has been working on for a few years.

Optimus has been a major focus of Tesla for the past several years, especially as Musk has said he believes it will be the biggest product of all time and could be the biggest contributor to the company’s valuation.

For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet:

The video shows Optimus working with a Kung Fu teacher, known as a Shifu, going through what appears to be some sort of routine of combinations. It’s quite impressive to see the fluidity of the movements and Optimus’s ability to keep up with Shifu.

Tesla has been “working hard” to scale Optimus production, Musk said last week, a project that has obviously confronted both AI and manufacturing teams with a variety of challenges.

The plan is to have an annual production run-rate of one million units by 2030, and there were plans to build 5,000 units this year.

Elon Musk gives update on Tesla Optimus progress

Musk still believes Optimus will make up roughly 80 percent of Tesla’s value. In January, he said it would be “overwhelmingly the value of the company.”

Tesla plans to launch the Gen 3 version of Optimus soon, and although a video of a new-look prototype was released by Marc Benioff, the CEO of Salesforce, the company’s frontman stated that this was not what the next-generation prototype would look like.

Elon Musk confirms Tesla has never shown Optimus V3 design yet

This video seems to show there is still significant progress being made on the Optimus project, and it will be perhaps one of the most impressive humanoid robots available to consumers in the coming years.

Tesla Full Self-Driving v14 gets new release date, Elon Musk details

“Last minute bug cropped up with V14. Released is pushed to Monday, but that gives us time to add a few more features.”

Tesla’s Full Self-Driving version 14 has gotten a new release date after new details from CEO Elon Musk opened up some new perspectives on the suite.

Originally slated for an “early wide release” of v14 this past week, then a launch of v14.1 and v14.2 this week and next week, respectively, delays arose after Tesla’s Autopilot team found some issues within the software.

Tesla FSD V14 set for early wide release next week: Elon Musk

Musk detailed on X this morning that a “last minute bug” appeared before release, which has now pushed FSD v14’s release back to this Monday:

Musk also said the delay would give Tesla the ability to “add a few more features,” which seems like an added advantage, although he did not provide any additional details on what these features could be.

In classic Musk fashion, he has teased the capabilities of this version of the FSD suite since it became public knowledge that Tesla was working on it. He said that it is the second most important update for the AI/Autopilot team since FSD v12.

V14 will have a parameter count that is ten times what previous iterations were, which should provide more accuracy and a more human-like operation.

Musk has said v14 “feels alive” and has used the word “sentient” to describe its performance. The goal with the new FSD rollouts is to eliminate as many interventions as possible, making it as close to human driving as possible.

Tesla just got a weird price target boost from a notable bear

Tesla stock (NASDAQ: TSLA) just got a weird price target boost from a notable bear just a day after it announced its strongest quarter in terms of vehicle deliveries and energy deployments.

JPMorgan raised its price target on Tesla shares from $115 to $150. It maintained its ‘Underweight’ rating on the stock.

Despite Tesla reporting 497,099 deliveries, about 12 percent above the 443,000 anticipated from the consensus, JPMorgan is still skeptical that the company can keep up its momentum, stating most of its Q3 strength came from leaning on the removal of the $7,500 EV tax credit, which expired on September 30.

Tesla hits record vehicle deliveries and energy deployments in Q3 2025

The firm said Tesla benefited from a “temporary stronger-than-expected industry-wide pull-forward” as the tax credit expired. It is no secret that consumers flocked to the company this past quarter to take advantage of the credit.

The bump will need to be solidified as the start of a continuing trend of strong vehicle deliveries, the firm said in a note to investors. Analysts said that one quarter of strength was “too soon to declare Tesla as having sustainably returned to growth in its core business.”

JPMorgan does not anticipate Tesla having strong showings with vehicle deliveries after Q4.

There are two distinct things that stick out with this note: the first is the lack of recognition of other parts of Tesla’s business, and the confusion that surrounds future quarters.

JPMorgan did not identify Tesla’s strength in autonomy, energy storage, or robotics, with autonomy and robotics being the main focuses of the company’s future. Tesla’s Full Self-Driving and Robotaxi efforts are incredibly relevant and drive more impact moving forward than vehicle deliveries.

Additionally, the confusion surrounding future delivery numbers in quarters past Q3 is evident.

Will Tesla thrive without the EV tax credit? Five reasons why they might

Tesla will receive some assistance from deliveries of vehicles that will reach customers in Q4, but will still qualify for the credit under the IRS’s revised rules. It will also likely introduce an affordable model this quarter, which should have a drastic impact on deliveries depending on pricing.

Tesla shares are trading at $422.40 at 2:35 p.m. on the East Coast.
