SpaceX and the company’s drone ship Of Course I Still Love You (OCISLY) have successfully wrapped up their second Falcon 9 recovery in less than two weeks, bringing booster B1051 back to Port Canaveral to be broken over and refurbished for a second launch.

Following its support of Crew Dragon’s thus far flawless launch debut, the booster will likely be exceptionally easy to turn around for its next flight. That second launch could occur as early as late April for Cargo Dragon’s 17th mission, a consequence of NASA’s desire to keep its SpaceX missions on boosters that are ‘in family‘ (i.e. only new boosters or flight-proven boosters that have only launched NASA payloads).

Although B1051’s reentry profile was relatively slow and gentle with main engine cut-off (MECO) and booster separation occurring at ~1.9 km/s (4250 mph) and 85 km (53 mi), its recovery was made intriguingly difficult by high seas at drone ship OCISLY’s Atlantic Ocean station. These bad conditions were readily visible at several points during SpaceX’s DM-1 livestream, with OCISLY heeling several degrees as the Falcon 9 booster’s Merlin 1D engine lit up the surrounding area like a floodlight. In fact, B1051’s post-landing struggle could actually be seen live as the booster clearly slide several meters across the drone ship’s deck almost immediately after touching down.

This issue of boosters sliding about and generally being difficult to deal with is actually one of the leading motivations that lead to SpaceX developing Octagrabber, a tank-like robot used to remotely secure recovery Falcon 9 first stages while minimizing the risk to the recovery team. In a situation like DM-1, with B1051 already sliding around OCISLY’s deck immediately after a night landing, Octagrabber would nominally be remotely activated and controlled, crawling from its garage to grab Falcon 9’s hold-down clamps and secure the stage with its own weight.

It’s actually unclear whether Octagrabber is capable of this sort of remote operation without SpaceX technicians aboard OCISLY, nor if SpaceX – as of late – has even tried to attempt to secure Falcon 9 boosters at night. The process of transferring crew between ships in heavy seas is actually quite dangerous on its own, so it would be less than surprising to hear that SpaceX’s recovery managers have cut down on nighttime operations in bad weather if Octagrabber can only be operated with crew present on OCISLY. For B1051, the drone ship, a tugboat, and crew boat GO Quest remained in the vicinity of the landing target until the following morning (still March 2nd) before beginning the ~500 km (~300 mi) trek back to Port Canaveral. Greeted by moody low-hanging clouds and scattered showers, observers were actually able to capture the rare sight – as pictured above – of Octagrabber being driven back into its blast shield/garage.

Regardless, future Commercial Crew launches – aside, perhaps, from SpaceX’s second demonstration launch (DM-2) later this year – will likely be able perform return-to-launch-site (RTLS) landings at the company’s Florida landing zones, much like Falcon 9 boosters already do after Cargo Dragon (CRS) missions. According to VP of Mission Assurance Hans Koenigsmann, B1051 had to conduct a drone ship (ASDS) recovery at sea due to NASA’s desire for conservative performance reserves to guard against the potential (and extremely unlikely) failure of one or several Merlin engines during the launch’s boost stage. In 2012, Falcon 9 suffered its first and only (known) in-flight Merlin failure, an anomaly which the rocket’s autonomously avionics perfectly dealt with to save the primary mission (Cargo Dragon’s operational debut, CRS-1). A secondary Orbcomm communications satellite sadly failed to make it to its operational orbit, however, classifying the mission as a partial failure. More recently, there have been unconfirmed hints pointing to other potential in-flight Merlin 1D failures, albeit during booster recovery attempts instead of the main boost phase. Whether or not those anomalies actually occurred, NASA is clearly all about extreme conservatism and ‘safety first’ approaches for the Commercial Crew Program (or at least SpaceX’s side of it).

SpaceX’s successful recovery of B1051 marks the company’s third launch and landing of 2019, thus far averaging a relatively slow one mission per month. While schedules can change, it currently appears that Crew Dragon’s DM-1 orbital debut will be the only SpaceX launch in March, barring Falcon Heavy’s own commercial debut occurring in the last few days of the month. According to a SpaceX representative speaking earlier this year, the company is actually aiming to equal or even surpass its 2018 record – 21 launches – in 2019, requiring a minimum average of two launches per month for the remainder of the year.

Numbers aside, SpaceX’s 2019 calendar will undoubtedly aim to surpass the number of major company milestones in a single year, a hard act to follow after 2017 and 2018. Ranging from the first operational Starlink satellite launches and the first SpaceX launch with astronauts aboard to major flight test and developmental milestones for the company’s next-gen Starship spaceship and Super Heavy booster, there are an incredible wealth of events to look forward to.

SpaceX posts Starship booster feat that’s so nutty, it doesn’t even look real

The Super Heavy booster’s feat was so impressive that the whole maneuver almost looked like it was AI-generated.

SpaceX has shared a video of a remarkable feat achieved by Starship’s Super Heavy booster during its 11th flight test.

The Super Heavy booster’s feat was so impressive that the whole maneuver, which was captured on video, almost looked like it was AI-generated.

Super Heavy’s picture perfect hover

As could be seen in the video shared by SpaceX, Starship’s Super Heavy booster, which is nearly 400 feet tall, smoothly returned to Earth and hovered above the Gulf of America for a few seconds before it went for its soft water landing. The booster’s picture-perfect maneuver before splashing down all but capped a near-flawless mission for Starship, which is about to enter its V3 era with Flight 12.

The booster’s balance and stability were so perfect that some users on X joked that the whole thing looked AI-generated. Considering the size of Super Heavy, as well as the fact that the booster was returning from space, the hovering display all but showed that SpaceX is dead serious about keeping its dominant lead in the spaceflight sector.

Starship V2’s curtain call

As noted in a Space.com report, Flight Test 11 achieved every major goal SpaceX had set for the mission, including deploying Starlink mass simulators, relighting Raptor engines in space, and executing a stable reentry for both the Starship Upper Stage and the Super Heavy booster. The feat also marked the second time a Super Heavy booster has been reflown, a milestone in SpaceX’s quest to make the entire Starship system fully reusable.

Starship’s V2 vehicle will now give way to the upgraded Starship V3, which is designed for faster turnaround and higher payload capacity. The Starship program is expected to pursue even more aggressive targets in the coming months as well, with Elon Musk stating on social media platform X that SpaceX will attempt a tower catch for Starship Upper Stage as early as spring 2026.

Elon Musk has revealed the tentative timeframe for Starship’s next milestone that would push the spacecraft’s reusability to a whole new level. 

Following Flight 11’s flawless mission, Musk noted on X that SpaceX will be aiming to catch the Starship Upper Stage with its launch tower as early as spring 2026. This should pave the way for SpaceX to start optimizing Starship for maximum reusability.

Flight 11 closes the Starship V2 chapter on a high note

Starship’s eleventh flight, which launched from Starbase, Texas, achieved every major mission objective. The Super Heavy booster completed a successful ascent, hover, and soft splashdown in the Gulf of America, while the upper stage executed an orbit burn, deployed Starlink simulators, and returned with a controlled reentry over the Indian Ocean.

This mission officially closed the chapter on the second-generation Starship and first-generation Super Heavy booster, and it set the stage for a redesigned vehicle built for orbital payload missions, propellant transfer, and beyond. It should be noted that Elon Musk has mentioned on X that Starship V3, at least if things go well, might be capable of reaching Mars.

Elon Musk confirms tower catch attempt set for spring

After Flight 11’s success, Musk confirmed that SpaceX will attempt to catch the Starship Upper Stage with its launch tower arms, fondly dubbed by the spaceflight community as “chopsticks,” in the coming months. Musk’s announcement came as a response to an X user who asked when the tower could start catching the Starship Upper Stage. In his reply, Musk simply wrote “Springtime.”

Starship’s reusability is a key feature of the spacecraft, with SpaceX aiming to achieve a launch cadence that is almost comparable to conventional aircraft. For such a scenario to be feasible, launch tower catches of both Starship’s Upper Stage and its Super Heavy booster have to be routine.

SpaceX is preparing to launch its final Starship V2 rocket on October 13, 2025. The launch closes the curtain on Starship V2 and marks the start of the ambitious spacecraft’s V3 era. 

Liftoff for Flight 11 is scheduled for 7:15 p.m. ET from Starbase in South Texas, with a 75-minute launch window. The mission will test reentry dynamics, new landing burn configurations, and heat-shield upgrades ahead of the transition to the next-generation Starship V3.

Starship V3 and beyond

Elon Musk confirmed on X that Starship V3 is already in production and could be “built & tested” and perhaps even flown before the end of 2025. The new version is expected to feature major performance and scale improvements, with Musk stating that Starship V3, provided that things go well, might be capable of reaching Mars, though V4 is more likely to perform a full-scale mission to the red planet. 

“Only one more V2 left to launch,” Musk wrote back in August following Starship’s successful Flight 10 mission. In another post, Musk stated that “Starship V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”

Starship V2’s final mission

Flight 11 is designed to push the limits of Starship V2. SpaceX engineers have intentionally removed heat-shield tiles in vulnerable areas to analyze how the vehicle handles atmospheric reentry under stress, as noted in a Space.com report. The test will also refine subsonic guidance algorithms and new landing burn sequences for the Super Heavy booster that would be used for Starship V3.

“Super Heavy will ignite 13 engines at the start of the landing burn and then transition to a new configuration with five engines running for the divert phase. Previously done with three engines, the planned baseline for V3 Super Heavy will use five engines during the section of the burn responsible for fine-tuning the booster’s path, adding additional redundancy for spontaneous engine shutdowns. 

“The booster will then transition to its three center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America,” SpaceX wrote in a post on its official website.
