SpaceX will modify engine component after concerns raised over cracking
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.

Elon Musk shares updated Starship V3 maiden launch target date
The comment was posted on Musk’s official account on social media platform X.
SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.
The comment was posted on Musk’s official account on social media platform X.
Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.
Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.
Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.
Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.
Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.
Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.
Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.

Tesla opens first public Tesla Semi Megacharger site in Los Angeles
The development was highlighted in a post on social media platform X by the official Tesla Semi account.
Tesla has opened its first public Tesla Semi Megacharger site in Los Angeles. The station reportedly offers up to 750 kW charging speeds and is open to Tesla Semi customers.

Tesla Semi Megachargers
The Los Angeles site seems to be the first public Tesla Semi Megacharger that is not located at a Tesla factory. It is also the third Megacharger site currently visible on Tesla’s map.
The Megacharger system is designed specifically for the Tesla Semi and is capable of delivering extremely high charging speeds to support long-haul trucking operations. Infrastructure such as this will likely play a key role in making the Semi competitive with diesel-powered transport trucks.
Tesla’s progress with the Semi has also drawn attention in recent days after Elon Musk biographer Ashlee Vance shared photos from inside the Tesla Semi factory near Giga Nevada. The images suggested that preparations for higher production volumes may be underway, hinting that a broader ramp of the Tesla Semi’s production indeed be approaching.
New deployment strategies
Tesla has continued expanding its broader charging network through several new strategies aimed at accelerating infrastructure deployment. One of these initiatives is the Supercharger for Business program, which allows third parties to purchase Tesla Supercharger equipment and deploy charging stations while still integrating with Tesla’s network.
The program recently marked a milestone in Alpharetta, Georgia, where the city deployed four 325 kW city-branded Superchargers near the Alpharetta Department of Public Safety on Old Milton Parkway. The chargers support the city’s Tesla Model Y police vehicles while also remaining accessible to the public.
As per a report from EVwire, the project was designed not only to support fleet charging but also to generate economic returns that could offset the city’s investment. Tesla’s Supercharger for Business program has already attracted several participants, including businesses and charging providers such as Suncoast Charging, Pie Safe bakery in Idaho, Francis Energy in Oklahoma, and Wawa convenience stores.

The Boring Company’s Vegas Loop moves 82k riders during CONEXPO
The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.
The Boring Company said its Vegas Loop system transported roughly 82,000 passengers during the recent CONEXPO-CON/AGG construction trade show in Las Vegas. The event was held at the Las Vegas Convention Center (LVCC) from March 3-7, 2026.
The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.
CONEXPO-CON/AGG 2026
CONEXPO-CON/AGG is one of the largest construction trade shows in North America. This year’s event was quite impressive, attracting more than 140,000 construction professionals from 128 countries across the world.
Considering the number of this year’s attendees, the LVCC Loop seemed to have proven itself to be a very useful transportation solution. A video posted by The Boring Company on its official X account featured attendees expressing their enthusiasm for the underground transport system, with some stating that they would like to see similar tunnels across Las Vegas.
The LVCC Loop is only part of the greater Vegas Loop network, which is actively under construction.
New Vegas Loop extensions
One of the newest additions is a station at the Fontainebleau Las Vegas resort on the Strip. The station is located on level V-1 of the resort’s south valet area, according to a report from the Las Vegas Review-Journal. From the Fontainebleau, passengers can travel free of charge to stations serving the Las Vegas Convention Center, as well as to Loop stations at Encore and Westgate.
The system is also expanding beyond the Strip corridor. In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. These trips include a limited above-ground segment after receiving approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.
The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. The extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station just north of Tropicana Avenue.
