SpaceX is T-18 hours to its second Falcon Heavy launch in barely 70 days, set to lift off with the Department of Defense’s Space Test Program-2 (STP-2) rideshare mission no earlier than (NET) 11:30 pm EDT (03:30 UTC), June 24th.

According to SpaceX CEO Elon Musk, STP-2 is without a doubt the company’s “most difficult launch ever”, owing to a multitude of high-stakes performance requirements, US military and NASA oversight, several technical milestones, challenging booster and fairing recoveries, and much, much more. Should SpaceX succeed on all fronts, the company will have taken a massive leap towards being able to offer competitive launch services that can fulfill all of the US government’s many different spaceflight needs.

Challenges all the way down

Likely the single most challenging aspect of STP-2 is the performance the mission’s Falcon 9 upper stage will have to deliver. SpaceX describes the challenge below:

“[The STP-2 mission] will deliver 24 satellites to space on the DoD’s first-ever SpaceX Falcon Heavy launch. [It] 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.”

According to older USAF documents (STP-2’s original launch target was mid-2015), those numbers could actually rise as high as five separate upper-stage Merlin Vacuum burns and a mission duration of more than 7.5 hours. Given the last-second decision to move Falcon Heavy’s center core recovery from ~40 km offshore to more than 1240 km offshore, it’s fairly likely that five burns and 7.5 hours will be closer to the reality of STP-2. In short, the center core will move from a gentle recovery to what will probably be SpaceX’s hottest and hardest booster recovery ever to transfer as much margin as possible to STP-2’s upper stage.

With regard to that extra spicy reentry, Falcon Heavy center core B1057 – the second Block 5 center core built by SpaceX – is now expected to attempt a landing aboard drone ship Of Course I Still Love You (OCISLY) more than 1240 km (770 mi) off the coast of Florida, potentially smashing the current record of ~970 km (600 mi).

At the same time, fairing recovery vessel GO Ms. Tree (formerly Mr. Steven; renamed due to change in ownership) is steaming hard, heading anywhere from 1400-1600 km into the Atlantic Ocean. Falcon Heavy STP-2 will be the vessel’s first attempted fairing catch since December 3rd, 2018, nearly seven months ago. It will likely crush the previous record for most distant fairing recovery attempt by 50% or more. Whether or not the vessel succeeds and catches its first Falcon fairing(s) ever, it’s exciting to see Ms. Tree (Mr. Steven) out and about for a fairing recovery after months of inactivity.

As always, SpaceX will host an official Falcon Heavy STP-2 livestream, beginning around T-15 minutes and likely lasting at least 1-2 hours as the rocket’s upper stage prepares for a ~7.5-hour orbital marathon.

SpaceX achieved its 100th Starlink mission of the year on Friday, October 31, marking another milestone for 2025. 

A Falcon 9 rocket carrying 28 Starlink broadband satellites successfully lifted off from Vandenberg Space Force Base in California at 4:41 p.m. ET, carrying another 28 Starlink satellites to Low Earth Orbit (LEO).

Falcon 9 booster’s 29th flight

Roughly 8.5 minutes after liftoff, the Falcon 9’s first stage touched down on the drone ship Of Course I Still Love You in the Pacific Ocean. This marked the booster’s 29th flight, which is approaching SpaceX’s reuse record of 31 missions.

This latest mission adds to SpaceX’s impressive 138 Falcon 9 launches in 2025, 99 of which were dedicated to Starlink, according to Space.com. The company’s focus on reusing boosters has enabled this breakneck pace, with multiple launches each week supporting both Starlink’s expansion and external customers.

Starlink’s network continues massive global expansion

Starlink remains the largest active satellite constellation in history, with more than 10,000 satellites launched, nearly 8,800 of which are currently active. SpaceX recently achieved Starlink’s 10,000-satellite milestone. With 100 Starlink missions completed for 2025, space enthusiasts have noted that SpaceX has successfully launched 2,554 Starlink satellites so far this year.

Starlink, which provides high-speed, low-latency internet connectivity even to the world’s most remote areas, has been proven to be life-changing technology for people across the globe. The service is currently operational in about 150 countries, and it currently has over 5 million subscribers worldwide. From this number, 2.7 million joined over the past year.

Tesla shares updated timeframe for Cybertruck FSD V14 release

The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.

Tesla’s Full Self-Driving (FSD) V14 update for the Cybertruck could arrive this weekend, as per recent comments from Director of Autopilot Software and VP of AI Ashok Elluswamy. 

The Cybertruck was expected to receive FSD V14 before the end of the month, but Tesla was not able to meet the target.

Considering the extended wait for FSD V14, it was no surprise that several Cybertruck owners were asking for updates about the system’s rollout to the all-electric pickup truck on Friday. These included the official Cybertruck X account, which responded to Elluswamy’s end of month estimate with “I only see trick. Where is my treat.” 

This prompted a response from the AI executive, who replied with, “Sorry, pushing for early access Cyber release over the weekend.” This means that if all goes well, Cybertruck owners would be able to experience FSD V14 very soon. Some, however, are wondering if Tesla would go straight to V14.2 for the Cybertruck’s FSD V14 update, or if the vehicle will receive V14.1 first. 

Tesla pushes to unify FSD experience across its lineup

The upcoming Cybertruck rollout represents the next step in Tesla’s efforts to roll out FSD capabilities across all of its vehicles. FSD V14 is a notable step forward for the company’s AI-driven self driving system, with features like Mad Max mode getting positive reviews from longtime Full Self Driving testers.

For the Cybertruck, the FSD V14 update would mark one of its first major over-the-air upgrades for the vehicle. Likely due to its size, the Cybertruck tends to receive FSD updates later than the S3XY lineup, which is quite surprising considering that the all-electric pickup truck is a premium-priced vehicle that is home to some of Tesla’s most advanced technologies.

Tesla has launched a new service designed to make its Full Self-Driving (FSD) technology familiar to all commuters. 

Dubbed the “Tesla Ride” program, the initiative aims to bring supervised Full Self-Driving demos and Grok AI-guided experiences to consumers in real world trips. 

How Tesla Ride Works

As per the official Tesla Ride website, the session will allow participants to sit in the driver’s seat while a Tesla Advisor rides shotgun as co-pilot. The Tesla Advisor then guides riders through the company’s latest supervised FSD features, comfort settings, and in-car entertainment. Participants would also be able to interact with Grok AI in the vehicles. Grok will be capable of answering questions during the ride, and it will even tell stories along the way.

Tesla noted, however, that Tesla Ride sessions are capped at 45 minutes each, and it requires participants to have a valid driver’s license and insurance. Interested participants are also advised to call beforehand so they can schedule their Tesla Rides.

Marketing push and reach

The Tesla Ride program runs across several markets from October into November, and in some locations into the end of December 2025. Participating states are numerous, from Michigan to Virginia to Illiois, Nevada, and California, among others. A look at the official webpage for Tesla Ride shows that the company is still taking a very cautious approach with the program, with disclaimers clearly stating that FSD Supervised does not make Teslas autonomous just yet.

Tesla’s focus on safety with FSD was highlighted recently by Senior Vice President for Automotive Tom Zhu. “Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. 

“The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” the executive stated.
