SpaceX rapidly turns around drone ship for sixth launch this month
SpaceX has rapidly turned around one of its two East Coast ‘autonomous spaceport drone ships’ and sent the vessel back to sea to support the sixth and final Falcon 9 launch planned this month.
SpaceX began the month with the successful launch of Transporter-4 – its fourth dedicated smallsat rideshare mission – on April 1st. Axiom-1 – the first all-private astronaut launch to the International Space Station – followed on April 8th. On the West Coast, another Falcon 9 rocket launched SpaceX’s second National Reconnaissance Office (NRO) spy satellite mission in two months on April 17th. Most recently, Falcon 9 booster B1060 tied SpaceX’s current 12-flight reusability record with the successful launch of a batch of Starlink satellites at 1:51 pm EDT on April 21st.
Drone ship Just Read The Instructions (JRTI) was tasked with supporting Falcon 9 booster recovery for Transporter-4 and Starlink 4-14. Now, less than a day after returning to Port Canaveral with booster B1060, the ship has been towed back to sea to support another Starlink launch and landing.
Due to almost two weeks of launch delays caused by Dragon recovery challenges, drone ship A Shortfall Of Gravitas (ASOG) – the second of two East Coast drone ships – has been stuck at sea while waiting to support NASA and SpaceX’s upcoming Crew-4 astronaut launch. To preserve plans for a late-April Starlink mission, SpaceX’s recovery team has needed to move about as fast as they ever have to allow JRTI to take ASOG’s place.
Following Starlink 4-14’s April 21st launch and landing, drone ship JRTI sailed into Port Canaveral around 2am EDT, April 24th. Within minutes of arriving at its usual berth, a dockside crane had swung over and begun installing a lifting cap on top of booster B1060. Less than four hours later, the booster was lifted off of JRTI’s deck and moved onto dry land, freeing up the space it occupied for any necessary inspections or repairs. The quick booster removal also gave SpaceX time to drive the drone ship’s robotic ‘Octagrabber’ recovery robot into a garage on its deck.
-->Just after 8pm EDT, less than 16 hours after JRTI reached its berth, support ship Bob towed the converted barge back out to sea. If Starlink 4-16 launches on time on April 29th, Just Read The Instructions will narrowly beat a three-year-old drone ship turnaround record (8d 6h) set by Of Course I Still Love You (OCISLY) in early 2019; recovering Falcon 9 booster B1062 just 8 days, 3 hours, and 42 minutes after Falcon 9 B1060 – and despite traveling ~1950 km instead of ~1850 km.
Ultimately, that distance is the main reason the current record has survived for so long. Short of building or modifying a new kind of recovery ship with a different type of hull, a flat-bottomed barge – towed or self-propelled – will never be able to traverse hundreds of miles of open ocean at high speeds.
Aside from breaking a potential drone ship turnaround record, Next Spaceflight reports that Starlink 4-16 will also almost certainly beat SpaceX’s current Falcon 9 booster turnaround record. Falcon 9 booster B1062 last launched Axiom-1 at 11:17 am EDT on April 8th. A 5:33 pm EDT, April 29th launch would translate to a turnaround time of 21 days and 6 hours, beating the current record of 27 days and 4 hours – set by B1060 in early 2021 – by more than a quarter.
If Crew-4 launches roughly on time, Starlink 4-14 will be SpaceX’s sixth launch in four weeks and 17th launch of 2022. If the company can sustain that pace over the remaining two-thirds of the year, it could feasibly launch more than 51 times in 2022.

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.
