After a one-day delay to replace a failed grid fin actuator, SpaceX is now less than 24 hours from the second test flight of Starship. SpaceX will have a 20-minute launch window that opens at 7:00 AM CT (13:00 UTC).

Making this test flight is Ship 25 and Booster 9. Ship 25 is powered by 6 Raptor engines (3 sea level and 3 vacuum), and Booster 9 is powered by 33 Raptor engines.

Booster 9 features many upgrades over the last booster to take flight, including better engine shielding and a switch from hydraulic thrust vector controls to electric TVC. Ship 25 didn’t see as many upgrades as the booster, and not much has been shared of any major changes that were made. One change to both vehicles was the improvement of the Flight Termination System, which took much longer to destroy the rocket than expected during the first test.

Launch Day

T minus 2 hours before the scheduled liftoff, the SpaceX launch director will give the go for propellant loading. This process will begin at t minus 1 hour and 37 minutes, and at this point, Booster 9 will begin loading with both liquid oxygen and liquid methane.

T minus 1 hour and 17 minutes, liquid methane will begin loading onto Ship 25, followed by liquid oxygen 4 minutes later at t minus 1 hour and 13 minutes.

T minus 19 minutes and 40 seconds, the 39 Raptor engines on Booster 9 and Ship 25 will begin chilling to prepare for the extremely cold fuel to flow through and prevent thermal shock to engine hardware.

T minus 10 seconds, the flame deflector installed after the first IFT will begin flowing water.

T minus 3 seconds, Raptor engine ignition begins, and thrust begins to build to allow for liftoff.

LIFT OFF!

T+ 2 seconds, the 2nd Integrated Flight Test should now be officially underway, with Booster 9 thundering away from the orbital launch mount.

T+ 52 seconds, Starship and Booster 9 reach Max Q, the area of maximum dynamic pressure on the vehicle will occur here. If (or most) all Raptor engines on Booster 9 are performing nominally, the vehicle will pass through this fairly quickly.

T+ 2 minutes and 39 seconds, Staging. This will be the first time SpaceX has ever attempted hot staging. Almost all of Booster 9 engines will cut out, and Ship 25 will ignite its Raptor engines to separate from the booster. This is all unknown territory from this point on for SpaceX, as the first test flight did not make it this far. SpaceX has yet to clarify how many Ship 25 engines will ignite during this process.

If all goes well, Booster 9 will begin its flip and boost backburn at t+ 2 minutes and 53 seconds, which will last ~54 seconds. Unlike the Falcon 9, the booster is not designed to perform an entry burn.

T+ 6 minutes and 30 seconds after lift-off, Booster 9 will begin its landing burn for a hopeful soft touchdown in the Gulf of Mexico 18 seconds after landing burn ignition. The planned landing area is ~20 miles (32 km) downrange.

Meanwhile, Ship 25 will continue burning its 6 Raptor engines until t+ 8 minutes and 33 seconds, inserted into a sub-orbital trajectory, and then enter a coast phase until its planned reentry North of the Hawaiian islands.

Landing!

At t+ 1 hour and 17 minutes, Starship will begin feeling the effects of the atmosphere, its first real test for the heatshield. If it survives atmospheric entry, Starship will splash down in the Pacific Ocean at t+ 1 hour and 30 minutes after lift off. SpaceX has said Ship 25 will not attempt a landing burn during this test.

If Starship is able to make it past staging, SpaceX will most likely consider this test a success, but it would be a major accomplishment for Ship 25 to survive entry back through the atmosphere and gather important data for the company.

If you have a chance to make it to South Texas or even the other side of the Rio Grande in Mexico, it’ll be a sight you’ll never forget. If you’re watching from home, SpaceX will begin streaming the launch on X and their website 35 minutes before lift-off.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Published

on

Tesla has officially launched the Model Y L in the United States and Puerto Rico for $61,990. It is the longer-wheelbase version of the Model Y, and has been available in China since last year.

Tesla brings the Model Y L to the U.S. just months after it phased out the only pure SUV in its lineup, the Model X. It is slightly longer than the Model Y configurations that are already available in the U.S., and features a three-row, six-seat setup with Captain’s Chairs being among the many features that make this a truly fantastic offering.

The Model Y L is priced competitively at $61,990, and features 325 miles of range and a 0-60 MPH in just 4.4 seconds.

Tesla also added a handful of new features that are not available in even the Premium Model Y. Here’s a full list of its features:

  • Heated/Ventilated Front Seats with Powered Thigh Cushion
  • Heated/Ventilated Captain’s Seats in Second Row with Powered Armrests & One-Touch Fold
  • Heated Third-Row Seats with Power Recline, One-Touch Fold & Child Seat Anchors
  • Improved Airflow, Increased Efficiency, More Range
  • 89 cubic feet of trunk space
  • Upgraded Acoustic Glass and Suspension to Minimize Road Noise
  • Adaptive Damping for a Smooth, Stable Ride
  • Staggered Tires for Enhanced Grip
  • Larger Tailgate for Better Rear Visibility and Bigger Windows Overall
  • 16″ First Row and 8″ Second Row Touchscreens
  • 19-Speaker Immersive Tesla Audio
  • 50W Wireless Charging Pads with Active Cooling and Charging Ports for All Other Seats
  • FSD Supervised and Integrated Grok AI

Tesla is also delivering these first units as a “Launch Series,” which comes with additional features, such as:

  • Door Trim Puddle Lights
  • Suede Dashboard Wing
  • Exterior and Interior Badging
  • Floor Mats
  • Sill Plates

The launch of the Model Y L in the U.S. marks a huge offering from Tesla to U.S. consumers. People have been calling for Tesla to bring a larger car to the U.S., and it needed it more than ever now that the Model X is gone.

It is a huge accomplishment for Tesla to get the Model Y L to the U.S., and after reporting strong deliveries today, it will be interesting to see how this car impacts future quarterly delivery reports.

Deliveries for the Model Y L “Launch Series” are slated for September or October of this year.

Tesla just told us twice that Model Y L is coming to the U.S.

Tesla just told us twice that the Model Y L is coming to the U.S., and two social media posts definitely just tipped the company’s hand, as if they wanted it to be any other way.

The two social media posts basically confirm that the slightly longer version of the Model Y will be heading to the United States soon, and many have speculated that the company could launch the vehicle as soon as this weekend.

The first post was directly from Tesla, and it showed an incredibly long Dachshund, with words above that said, “Looking forward to the long weekend.”

Anyone who knows Tesla knows the company loves to troll its fans and have fun, and this is a perfect example of that. While not a direct acknowledgement, Tesla is very involved on social media, especially CEO Elon Musk’s platform X, and the company is well aware of what is being discussed within the community.

With recent sightings of Model Y L test mules in California, peeks of the vehicle at Giga Texas, and a large call for the car to come to the U.S., Tesla is simply stoking conversation with this.

However, the company also made another move that was recognized on social media. Tesla has a large gallery that includes photos of its products so media and others can use them. This gallery applies to the U.S. market specifically, unless otherwise specified.

Tesla uploaded a Model Y L to the Gallery last night:

This seems to be another indication that the Model Y L is coming to the United States.

Musk said last year that the Model Y L could make its way to the United States late this year, but it was not something that was set in stone by Tesla. The company definitely needs to establish something in the SUV market that is larger than the Model Y, and the Model Y L might be the answer.

Even still, there are consumers out there who would love Tesla to develop something even larger, like a competitor to the Tahoe or Expedition. Tesla has not really given much of an indication that it will go in that direction.

Tesla is using vehicle microphones to improve build quality: here’s how

Published

Tesla is using the vehicles’ internal microphones to improve build quality, Vice President of Engineering Lars Moravy revealed recently.

It’s no secret that Tesla is always finding ways to make its manufacturing operations more efficient, accurate, and valuable. Constantly trying to make its cars better, the company has never placed any restrictions on what it will do to improve everything from panel gaps to paint.

As Teslas have been driving autonomously on the property of the Gigafactory Texas plant for a while now, Moravy revealed to Herbert Ong in a new interview that cars rolling off production lines now autonomously navigate themselves through a bumps, squeaks, and rattles (BSR) portion of the line. This helps to identify any loose or improperly installed internal parts.

The cabin’s microphones, which are used for a variety of things in ownership, simultaneously monitor any noises inside the vehicle while it rolls through the BSR portion of the production line. Moravy actually revealed that Tesla is trying to build “Full Self-Hearing,” an AI system that will detect minor imperfections so they can be corrected before delivery.

It’s no secret that build quality is something that Tesla struggled with as it scaled to a fully massive production operation that manufactures over 1.6 million vehicles per year. However, in recent years, especially, there have not been as many complaints. Tesla has truly improved upon its build quality and paint quality over the past several years, especially in the U.S.

Tesla’s ‘megacasts’ are key to massive build quality improvements

While those improvements have been evident, there are still some complaints; no automaker is perfect with this. But this step will now ensure that every single car that rolls off the production lines at Gigafactory Texas will be void of any creaks, squeaks, or squeals when it leaves the factory.

This measure is one of the most unique we’ve seen in terms of a strategy to avoid build quality issues, but it is not exclusive to Tesla.

Ford uses acoustic analysis AI to find abnormalities in seat motors, climate control units, and other components. Suppliers and OEMs will also use microphone arrays or particle velocity sensors in end-of-line stations.
