After a few late-stage schedule tweaks, SpaceX’s third Falcon Heavy launch – set to deliver 24 spacecraft to a variety of orbits – is ready to usher the US Air Force into a new age of commercial rocket reuse as early as 11:30 pm ET (03:30 UTC), June 24th.

Split among the USAF, Department of Defense (DoD) research labs, NASA, NOAA, and a few US universities, STP-2’s 24 satellites will launch aboard SpaceX’s second Falcon Heavy Block 5 rocket. Both side boosters are flight-proven, having supported Falcon Heavy Block 5’s launch debut on April 11th, just 54 days ago. If all goes as planned, STP-2 will simultaneously give the USAF the data it needs to fully certify Falcon Heavy for all military launches and set the US military up to certify flight-proven commercial rockets for future launch contracts.

Signalling just how important the company feels this mission is, a dedicated STP-2 website created by SpaceX offers an excellent explanation of all aspects of the mission, from the technical to the strategic.

The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours. In addition, the U.S. Air Force plans to reuse side boosters from the Arabsat 6A Falcon Heavy launch, recovered after a return to launch site [RTLS] landing, making it the first reused Falcon Heavy ever flown for the U.S. Air Force.

[STP-2] will demonstrate the capabilities of the SpaceX Falcon Heavy launch vehicle and provide critical data supporting certification for future National Security Space Launch (NSSL) missions. In addition, [the Air Force Space & Missile Systems Center (SMC)] will use this mission as a pathfinder for the development of mission assurance policies and procedures related to the reuse of launch vehicle boosters.

Following the ~June 1st arrival of Falcon Heavy center core B1057, all STP-2 launch hardware is now on site at SpaceX’s Pad 39A launch complex and nearby payload processing facilities. Although we will have to wait for official photo confirmation, SpaceX is likely in the late stages of integrating Falcon Heavy’s three boosters and upper stage, while some combination of DoD and SpaceX technicians are presumably in the middle of preparing all 24 STP-2 satellites for launch.

Falcon Heavy Flight 3’s next visible milestone will probably be the integrated rocket’s roll-out to Pad 39A for a routine static fire test, likely to occur 3-7 days prior to June 24th.

Record-breaking reusability

Incredibly, despite the schedule overhead likely added by this mission’s crucial pathfinder nature, the current June 24th launch date would permit side boosters B1052 and B1053 to simultaneously break SpaceX’s current booster turnaround record. Set in mid-2018 by B1045 on SpaceX’s last non-Block 5 launch, the record turnaround (time between launches) of 72 days would be beaten at 68 days for STP-2, barring any additional delays.

Whether STP-2’s side boosters literally beat SpaceX’s 72-day reusability record is immaterial to the actual significance of this milestone. If SpaceX can beat its old record as part of what is arguably its most complex launch ever, it’s safe to say that Block 5 reusability – particularly for gently-used boosters – is already a spectacular success. It also suggests that SpaceX technicians and launch engineers are becoming extremely familiar and comfortable with Falcon Heavy launch operations, to the extent that two boosters used on two Falcon Heavy launches could break SpaceX’s most significant reusability record.

Tesla Giga Berlin growth could stall if not “free from external influences”: Elon Musk

The comments were delivered in a pre-recorded video discussion.

Tesla CEO Elon Musk has reportedly warned that future expansion of Gigafactory Berlin could be jeopardized if the site does not remain “free from external influences.”

Musk’s comments were delivered in a pre-recorded video discussion with employees and came at a sensitive moment for the facility, where union representation has been a recurring issue.

According to reports from Handelsblatt and Der Spiegel, citing participants at the event, Musk suggested that if Giga Berlin is no longer “free from external influences,” further expansion would become unlikely. He did not, however, hint that the plant would shut down.

While Musk did not name IG Metall directly, his remarks were widely interpreted as referencing the union, which is currently the largest faction on the works council but does not hold a majority, as noted in an electrive report.

The video conversation was conducted between Musk in Austin and Grünheide plant manager André Thierig, then played back to the workforce in Germany. Works council elections are scheduled for early March, heightening the tension between management and organized labor.

The CEO has previously voiced concerns that stronger union influence could limit Tesla’s operational flexibility and long-term strategy in Germany.

Despite the warning on expansion, Musk praised the Giga Berlin site during the same address, describing it as one of the most advanced factories worldwide and highlighting its cleanliness and team culture.

The discussion also reportedly touched on battery cell production. According to attendees cited in German media, Musk indicated that Tesla has begun ramping cell production at the site. That would mark a notable shift from earlier expectations that large-scale cell manufacturing in Brandenburg would not begin until 2027.

Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.

According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.

With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.

A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.

This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.

FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.

Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.

When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.

Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.

The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.

According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.

“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”

By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.

“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.

The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.

The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.
