SpaceX will modify engine component after concerns raised over cracking

Published

on

The Government Accountability Office is about to issue a report warning of a flaw it believes exists in the Merlin engines used to power the SpaceX Falcon 9 rockets. A report in the Wall Street Journal claims the GAO has determined there is a flaw in the turbopumps that pressurize the two fuels used in the Merlin engines — liquid oxygen and highly refined kerosene — and force them into the engines’ combustion chamber.

A draft of the report says turbine blades in the pumps are cracking under pressure. The GAO is concerned that the cracking problem makes the Falcon 9 unsafe for crewed space missions, which are scheduled to begin in 2018. For its part, SpaceX says it is aware of the problem and is taking steps to address the issue.

“We have qualified our engines to be robust to turbine wheel cracks,” SpaceX said in a statement made in response to an inquiry from Quartz. “However, we are modifying the design to avoid them altogether. This will be part of the final design iteration on Falcon 9. SpaceX has established a plan in partnership with NASA to qualify engines for manned spaceflight.”

No failures have occurred due to the cracked turbine blades. The Falcon 9 has completed 28 successful missions since its first flight in 2010. The two failures that did occur — one in 2015 and another in 2016 — were attributed to other causes.

Part of the concern is that SpaceX intends to be the first to re-use its rockets as part of its push to drive down the cost of space launches. There are fears that the cracking problem could lead to more failures when rockets are re-used, although it seems unlikely SpaceX would rely on rocket engines it knows have cracked turbine blades.

What is not known at this time is how long it will take SpaceX to complete and validate the changes to its rocket engine design. There are concerns the changes may delay the company’s ambitious 2017 launch schedule, which could have a negative effect on its profitability. Acting NASA administrator Robert Lightfoot told the Wall Street Journal, “we know how to fix” the SpaceX engines but did not suggest how long it will take to incorporate and test the design changes.

Boeing, which is SpaceX’s closest competitor in the space flight business, is experiencing its own problems of late. Aerodynamic turbulence between its spacecraft, the CST-100, and the Atlas rockets Boeing intends to use has caused serious vibrations during testing. The vibrations are powerful enough to cause concerns about the safety of the rocket and spacecraft combination. It is also experiencing problems with the parachutes that are supposed to return the spacecraft and the humans inside safely to earth at the conclusion of a mission.

Quartz reports that independent experts are concerned that neither company will have their rockets and space capsules ready in time to meet NASA 2018 manned flight schedule.

After overcoming fire safety hurdles, the Boring Company is accelerating its Vegas Loop expansion. The project’s progress signals a transformative boost for Sin City’s transportation and tourism.

Elon Musk’s tunneling company, along with The Las Vegas Convention and Visitors Authority (LVCVA) and Clark County, resolved fire safety concerns that delayed new stations.

“It’s new. It’s taken a little time to figure out what the standard should be,” said Steve Hill, LVCVA President and CEO, during last week’s board meeting. “We’ve gotten there. We’re excited about that. We’re ready to expand further, faster, than we have.”

Last month, the company submitted permits for tunnel extensions connecting Encore to a parcel of land owned by Wynn and Caesars Palace. The three tunnels are valued at $600,000 based on country records.

Plans for a Tropicana Loop are also advancing, linking UNLV to MGM Grand, T-Mobile Arena, Allegiant Stadium, Mandalay Bay, and the upcoming Athletics’ ballpark. Downtown extensions from the convention center to the Strat, Fremont Street Experience, and Circa’s Garage Mahal are also in the permitting process.

“Those are all in process,” Hill noted. “We’ve got machines that are available to be put in the ground. I think we’ve reached a framework for how these projects are going to work and how they’ll be permitted from a safety standpoint, as well as a building standpoint.”

The Boring Company has six boring machines, with three currently active in Las Vegas. Last week, TBC announced that it successfully mined continuously in a Zero-People-in-Tunnel (ZPIT) configuration, enabling it to build more tunnels faster, safer, and at a more affordable rate.

Tunneling under Paradise Road is underway as The Boring Company works on the University Center Loop. The University Center Loop is expected to connect to the Las Vegas Convention Center within two months, linking to the Westgate tunnel. The full Vegas Loop will span 104 stations and 68 miles. Even though The Boring Company’s tunnel network in Las Vegas isn’t nearly finished, it has already become a key attraction in the city.

“It’s such a great attraction for shows that are looking at this building (convention center) and we’re going to be connected to everybody in town,” Hill said. “It’s a real difference-maker.”

A few Vegas Loop stations are already operational, including those connected to Resorts World, Westgate, Encore, and all the Las Vegas Convention Center Loop stations. The Downtown Loop, which connects to the downtown area, and the Riviera Station, the hub that leads to Resorts World with Westgate destinations, are also operational.

As The Boring Company accelerates the Vegas Loop, its tunnels are poised to redefine mobility and tourism in Las Vegas, blending cutting-edge technology with practical urban solutions.

Neuralink Blindsight human trials expected to start in the UAE

Neuralink aims to restore vision with its Blindsight BCI implant. First human implant for Blindsight may happen in UAE.

During Elon Musk’s interview at the Qatar Economic Forum, he announced that Neuralink aims to implant its Blindsight brain-to-computer interface (BCI) device in a human patient by late 2025 or early 2026.

Blindsight focuses on restoring vision. A few years ago, Musk mentioned that Neuralink’s BCI devices would restore vision for people, even those born blind.

“The first two applications we’re going to aim for in humans are restoring vision, and I think this is notable in that even if someone has never had vision ever, like they were born blind, we believe we can still restore vision. The visual part of the cortex is still there. Even if they’ve never seen before, we’re confident they could see,” Musk said during Neuralink’s Show & Tell in 2022. 

Musk said Blindsight could be implanted into a human patient in the United Arab Emirates (UAE). Neuralink plans to partner with the Cleveland Clinic Abu Dhabi to implant the first human patient with Blindsight.

Elon Musk’s neurotechnology company is partnering with the Cleveland Clinic Abu Dhabi to conduct the first clinical trial of the UAE-PRIME study. Like Neuralink’s PRIME study in the United States, UAE-PRIME will focus on human patients with motor and speech impairments.

Neuralink received Food and Drug Administration (FDA) approval to conduct the PRIME and CONVOY studies in the United States. PRIME tests the capabilities of the company’s Link implant to restore or enable motor and speech in participants. Meanwhile, the CONVOY study explores Link’s ability to control assistive robotic devices. Neuralink already has an assistive robotic arm called ARA that could expand patients’ autonomy beyond smart devices.

Blindsight would probably require a separate study from PRIME and CONVOY. As such, Neuralink might need FDA approval in the United States to start human trials for Blindsight. However, Blindsight already received a “breakthrough device” designation from the US FDA.

In April 2025, Neuralink opened its patient registry to participants worldwide. The neurotechnology company has already implanted its Link BCI device into five patients. Earlier this year, Neuralink welcomed one of its first PRIME study participants as the first patient in its CONVOY study.

Elon Musk just revealed more about Tesla’s June Robotaxi launch

Tesla CEO Elon Musk gave more information about the Robotaxi launch in Austin set for June.

Tesla CEO Elon Musk just revealed more details about the company’s June Robotaxi launch, which will kick off in Austin.

As of right now, Tesla is still set to push out the first Robotaxi rides in Austin, Texas, in early June. These vehicles will be in short supply at first, as Musk says the company is purposely rolling out the fleet in a slow and controlled fashion to prioritize safety. There will be ten vehicles in the Robotaxi fleet to start.

Tesla Robotaxi deemed a total failure by media — even though it hasn’t been released

However, in an interview with CNBC on Tuesday afternoon, Musk also revealed some other new details, including where in Austin the vehicles will be able to go, how many Robotaxis we could see on public roads within a few months, and other information regarding Tesla’s Full Self-Driving suite.

A Controlled Rollout

Tesla has maintained for a few months now that the Robotaxi fleet will be comprised of between 10 and 20 Model Y vehicles in Austin.

The Cybercab, which was unveiled by the company last October, will not be available initially, as those cars will likely be produced in 2026.

Musk said during the CNBC interview that Tesla is doing a low-yield trial at first to initiate a safety-first mentality. It is important for Tesla to launch the Robotaxi fleet in a small manner to keep things in check, at least at first.

As confidence builds and the accuracy of the fleet is ensured, more vehicles will be added to the fleet.

Musk believes there will be 1,000 Robotaxis on the road “in a few months.”

Geofenced to Certain Austin Areas

Tesla will be launching the Robotaxi program in a geofenced fashion that gives the company the ability to control where it goes. Musk says that the areas the Robotaxis will be able to travel to are among the safest neighborhoods and areas in Austin.

This is yet another safety protocol that will ensure the initial riders are not put in dangerous neighborhoods.

Some might be disappointed to hear this because of Tesla’s spoken confidence regarding Robotaxi, but the initial rollout does need to be controlled for safety reasons. An accident or incident of any kind that would put riders’ lives in danger would be catastrophic.

No Driver, No Problem

As the company has rolled out an employee-only version of the Robotaxi program in Austin and the San Francisco Bay Area, some wondered whether the rides would be driverless, as these initial trials for Tesla workers were not. Employee rides featured a human in the driver’s seat to ensure safety.

The company did not report whether there were any interventions or not, but it did state that the vehicles traveled over 15,000 miles through 1,500 trips.

Musk confirmed during the interview that there will be no driver in the vehicle when the Robotaxi program launches in June. This will be groundbreaking as it will be the first time that Tesla vehicles will operate on public roads without anyone in the driver’s seat.

Full Self-Driving Licensing

For more than a year, Tesla has indicated that it is in talks with another major automaker regarding the licensing of Full Self-Driving. Many speculated that the company was Ford, but neither it nor Tesla confirmed this.

Musk said today that Tesla has been in touch with “a number of automakers” that have inquired about licensing FSD. Tesla has yet to sign any deal to do so.
