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.

President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.

The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.

Trump stated:

“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”

He added:

“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.

Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.

The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.

President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.

Tesla Cybercab launch is imminent after latest sighting at Giga Texas

Published

Tesla just gave what is perhaps its biggest signal yet that the launch of the Cybercab, its autonomous ride-hailing-geared car, is imminent.

The Cybercab has been spotted outside of Gigafactory Texas in massive numbers over the past few days, with hundreds of units being stored on property just days after the vehicle received a Certificate of Conformity from the EPA.

Today, things were a bit different.

Cybercabs spotted on Giga Texas property today had an addition: a Cybercab decal on the side, reminiscent of the “Robotaxi” ones that were placed on Model Ys just as the company launched its ride-sharing platform about a year ago.

Giga Texas drone operator Joe Tegtmeyer noticed the change today:

Tesla could be signaling that the Cybercab is preparing to enter the Robotaxi fleet in the coming weeks or months with this move. It seems more symbolic than anything; Tesla is ready to throw Cybercabs in the ride-hailing platform just as it did with Model Ys last year.

The addition of the Certificate of Conformity awarded to the Cybercab is another major factor working to Tesla’s advantage. The company now has permission from the EPA to allow the vehicle to operate on public roads and enter the chain of commerce. It’s officially street legal.

Tesla Cybercab specs revealed: range, curb weight, range ratings, and more

The big question that remains is whether Tesla will be able to operate the car without a safety monitor, especially considering it plans to put the car out there without a steering wheel or pedals. With the Cybercab only having a seating capacity of two, it is hard to believe Tesla will even consider putting a Safety Monitor in the car.

It did recently self-certify as Level 4 and has the ability to operate driverless vehicles in the State of Texas under a law that took effect on May 28. You can read more about that here:

Tesla’s Robotaxi dreams just took a massive step toward reality

We’d imagine Cybercabs will be on the roads as soon as July, but August will likely be a better estimate of when the car will be entered into the Cybercab fleet. It all depends at where Tesla is, as they’ve truly prioritized safety with the rollout of the Robotaxi platform.

Elon Musk says this part of Tesla ‘makes no sense’

Elon Musk has publicly questioned Moody’s credit assessments following the rating agency’s decision to assign SpaceX a Baa1 investment-grade rating, two notches above Tesla’s Baa3. The comments came amid discussions comparing the two companies’ financial profiles.

SpaceX earned its first-time Baa1 rating with a stable outlook from Moody’s. The agency highlighted the company’s leadership in orbital launches, the growing recurring revenue from its Starlink satellite network, strong vertical integration, U.S. government contracts, and emerging opportunities in AI infrastructure.

These factors were cited as supporting robust cash flows, margin expansion, and financial flexibility.

Musk responded directly: “Tesla’s credit rating is ridiculously low tbh,” and added, “Yeah, makes no sense. Tesla has over $40B in cash, no debt, and is consistently profitable!” His remarks underscored Tesla’s balance sheet strength and profitability at a time when many traditional automakers continue to report losses in the shift to electric vehicles.

Tesla maintains a leading position in the global EV market, with diversification into energy and storage, battery technology, and robotics through projects like Optimus. Recent financial updates show the company generated positive free cash flow of $1.4 billion in Q1 2026, supported by operating cash flow of $3.9 billion. Cash and short-term investments stood at approximately $44.7 billion.

Moody’s has affirmed Tesla’s Baa3 issuer rating with a stable outlook in periodic reviews, acknowledging the company’s EV leadership, technology strengths, including AI for autonomous vehicles, solid profitability, and strong liquidity.

However, the agency has also noted challenges in the automotive segment and expectations for margin pressures.

Musk’s critique highlights a common debate about how traditional rating methodologies apply to high-growth, capital-intensive technology companies. SpaceX benefits from long-term government-backed contracts and diversified, recurring revenue streams, while Tesla’s valuation reflects heavy investment in future technologies such as autonomy and robotics.

Both ratings remain investment-grade, yet the one-notch difference has fueled online discussion about potential inconsistencies in evaluating innovative firms.

The exchange comes as SpaceX explores financing options following its recent valuation milestones, while Tesla continues executing on its multi-year roadmap. Musk’s pointed response serves as a reminder that credit ratings, though influential for borrowing costs, represent one lens through which markets assess corporate strength—and that company leaders often view their financial positions through the lens of long-term innovation and cash generation rather than short-term risk metrics alone.
