NASA scrubs first SLS Moon rocket launch attempt
NASA has scrubbed the first attempted launch of its Space Launch System (SLS) Moon rocket after running into multiple issues, one of which could not be solved in time.
The delay is bad news for the tens to hundreds of thousands of tourists who traveled to Cape Canaveral, Florida to witness the launch in person. Worse, by NASA’s own implicit admission, there’s a good chance the main problem SLS encountered could have already been dealt with and rectified in advance of the launch attempt if the space agency had finished testing the rocket earlier this summer.
Ultimately, that omission turned the first SLS launch attempt into more of a continuation of the rocket’s first four wet dress rehearsal (WDR) attempts, none of which ended as expected. NASA engineers will now have to decide how to proceed and whether the SLS rocket can be made ready in time for another launch attempt on September 2nd or 5th. If not, the next opportunity could be weeks away.
As far as SLS test operations go, the August 28/29th launch attempt was fairly ordinary, with the rocket running into multiple issues – a few minor, a few significant, and one identical to a previous problem. The first problem – a hydrogen leak near the SLS rocket’s base – came after a risk of lightning delayed the start of propellant loading by more than an hour. A very similar, if not identical, hydrogen fuel leak had already occurred during official wet dress rehearsal testing in April and July.
That leak was fixed on the fly by properly chilling all related systems, and propellant loading was eventually completed – albeit a few hours late thanks to inclement weather. Shortly after, there were reports of a crack that needed careful analysis. Only later did NASA specify that the suspected crack was in the rocket’s foam insulation rather than its structures, the latter of which could have been a catastrophic problem.
Around the same time, the true showstopper of the day occurred when NASA attempted to chill the SLS Core Stage’s four RS-25 engines, all of which flew several times aboard reusable Space Shuttle orbiters. Three engines performed (mostly) as expected, flowing a bit of liquid hydrogen fuel to cool themselves down, but one – engine #3 – was never able to make progress toward the optimal temperature needed for ignition (~5°C/~41°F). After hours of remote troubleshooting attempts, no progress had been made, and NASA ultimately decided to scrub the launch attempt at T-40 minutes to liftoff.
Over the course of four separate wet dress rehearsal attempts in April and June 2022, NASA was never able to test the core stage’s engine chill capabilities. In a post-scrub press conference, Jim Free – NASA’s Associate Administrator of the Exploration Systems Development Division – revealed that all four engines were warmer than intended, further confirming that skipping a fully nominal wet dress rehearsal was likely a mistake. Clear and present evidence aside, Free stated that he and other executives still believed skipping that test was the right decision, claiming that ending explicit WDR testing reduced the number of times the rocket needed to be moved on its transporter.
Making the situation even harder to explain, Artemis I Mission Manager Mike Sarafin revealed in the conference Q&A that Boeing had changed the design of parts of the SLS engine chill (bleed) system after the Core Stage finally conducted a nominal static fire test at Mississippi’s Stennis Space Center. Completed in March 2021, the SLS rocket then sat inside NASA’s Kennedy Space Center, Florida Vehicle Assembly Building (VAB) for a full year before attempting its first wet dress rehearsal tests at the launch pad.
The first round of three WDRs were not as smooth as NASA expected and instead uncovered three relatively small issues: a hydrogen leak, a single faulty upper stage valve, and problems with a ground supply of nitrogen gas. Those small issues led NASA to roll SLS back to the VAB for repairs, incurring a minimum multi-week delay that stretched into two months. SLS also failed to complete a fourth WDR attempt in July 2022, but NASA decided to overlook the rocket parts and phases of preflight operations that were never actually tested as planned, one of which was the engine chill system.
If NASA cannot fix the RS-25 chill system within the next few days, it will be forced to roll the entire rocket and mobile launch platform back to the VAB to – at a minimum – replace its flight termination system (FTS). The US Eastern Range requires that all rocket FTS systems be tested no more than 15 days before launch, and NASA was able to secure special permission for a gap of up to 25 days. However, because Boeing’s Core Stage design places the FTS system in a location that is reportedly inaccessible at the pad, the entire SLS rocket will need to roll back to the VAB to have its FTS systems “retested” after that period.
As a result, NASA’s SLS launch debut will be delayed by several weeks (at best) if it can’t recycle for another attempt on September 2nd or 5th. The next window runs from September 20th to October 4th, but the SLS rocket took 10 days to go from its latest rollout to first launch attempt – a figure that doesn’t include the time required to remove the rocket from the pad, roll it back to the VAB, and conduct any necessary repairs or tests while back in the bay. If NASA can’t fix the engine problem at the pad by September 3rd or 4th, the true delay could be more like 4-6 weeks.
With any luck, that won’t happen, but it’s clear that a lot of stress and discomfort could have been avoided if NASA had gone into its first launch attempt knowing that its SLS rocket was truly ready.
Tesla owners are being doxxed by a controversial anti-DOGE website in what it called an act to “empower creative expressions of protest.”
Dogequest, a website that has been created with a clearly outlined use for intimidation against Tesla owners, posted the names, addresses, phone numbers, and other contact information of those who own vehicles made by the electric vehicle manufacturer.
It was spotted by 404 Media.
The site also claims to have the information of employees at the Department of Government Efficiency, as well as the addresses of Tesla dealerships and the locations of Tesla Superchargers. The latter two are public information.
However, the website is hoping to get Tesla owners to sell their vehicles in this evident intimidation tactic. However, the information on the website, while it was seen, was not verified to prove that it contained the information of real-world Tesla owners. The site was not accessible by Teslarati at the time of publication.
The creation of a site like Dogequest is just another level that anti-Elon Musk activists are taking to attempt to destroy a company like Tesla as its CEO works with the Trump Administration to eliminate excessive government spending through the work of DOGE.
It is also the latest attack on Tesla owners, who have seen their vehicles vandalized, damaged, and even destroyed by those who disagree with the actions of Musk.
Tesla as a company has also seen several acts of retaliation against it, as everything from the arson of its showrooms and vehicles to it being kicked from the popular Vancouver Auto Show have come as a result of the recent backlash against the company.
Moving forward, there are still questions surrounding how these attacks will be combatted. The Trump Administration has indicated that acts of vandalism against Tesla would be considered a federal crime, but the tricky part of locating the culprits has proven to be extremely difficult. Only a handful have been found and held accountable.
Tesla (NASDAQ: TSLA) received an upgraded rating on its shares from Wall Street firm Cantor Fitzgerald, who recently took a trip to Austin to visit the company’s data centers and production lines ahead of several high-profile product launches set for this year.
It was a bold move, especially considering Tesla shares are under immense pressure currently, fending off negative news regarding the company’s sentiment and potentially lower-than-expected delivery figures due to the launch of a new version of its most popular vehicle, the Model Y.
However, the bulls on Wall Street are still considering Tesla to be a safe play, especially considering its robust presence in various industries, including automotive, energy, and AI/Robotics.
Cantor Fitzgerald analyst Andres Sheppard said in a note that, during a recent visit to Tesla’s Cortex AI data centers and the production line at Gigafactory Texas, it was clear there is a lot of potential and runway for Tesla in 2025:
“On 3/18, we visited Tesla’s Cortex AI data centers and the factory’s production lines ahead of the company’s introduction of its Robotaxi segment (targeted for June in Austin, followed by CA later in 2025). With Tesla’s shares now down ~45% YRD, we upgrade Tesla to Overweight (from Neutral) ahead of upcoming material catalysts. Our $425 12-month PT is unchanged. Our Thoughts: Attractive Entry Point Ahead of Material Catalysts.”
Sheppard went on to mention the catalysts, which he believes are the Robotaxi rollout in Austin in June, along with the continued rollout of Full Self-Driving in China, the eventual rollout of FSD in Europe, and the introduction of the affordable models in the first half of this year, and those were just on the automotive side.
There are several others, including Optimus, growth in the energy division, and in the longer term, the Semi.
In terms of potential weaknesses, Sheppard expects the likely removal of the EV tax credit and some of its growth to be offset by tariffs as the two big things that stand in the way of even more growth for the company.
Tesla is up over 5 percent on Wednesday, trading at $236.86.
Tesla has been kicked from a popular automotive show as the organizers of the massive event have succumbed to the pressure of protestors and others who oppose the electric vehicle maker.
The Vancouver Auto Show in Canada announced that it would not allow Tesla to establish a presence at the event this year, citing concerns about potential disruption from protestors and others who have been vocal about their distaste for the company and its CEO, Elon Musk.
Eric Nicholl, executive director of the Vancouver Auto International Show, said (via The Hill):
“The Vancouver Auto Show’s primary concern is the safety of attendees, exhibitors, and staff. This decision will ensure all attendees can be solely focused on enjoying the many positive elements of the event.”
Tesla was reportedly given several opportunities to voluntarily withdraw from the Vancouver Auto Show. The company evidently declined these invitations. Reps of the event itself then took it into their own hands, stating that the company would not be welcome at the event any longer.
Musk’s involvement in the Department of Government Efficiency (DOGE) under the Trump Administration seems to be the main culprit for so much pushback from the opposition.
Protest groups and organizers have put together various acts of opposition against Tesla, some more reasonable than others, in an effort to show their distaste for the company and Musk. However, many of these acts have turned violent, resulting in the vandalism or even the total destruction of vehicles. It’s one thing to use your right to protest, and it’s another to destroy people’s personal vehicles or property that belongs to the automaker.
The decision by the Vancouver Auto Show sets a dangerous precedent that the violence and destruction tactics used by groups that oppose Tesla will work. Ultimately, people’s safety is most important, but there is the impression that shows will not take the proper precautions to ensure that all companies are able to show off their products and tech at the event.
This could have been resolved with other strategies, and axing Tesla from the show altogether could result in some fans boycotting the show altogether.
