SpaceX has suffered its second rocket landing failure of 2020 despite the fact that both lost Falcon 9 boosters successfully launched 60 Starlink satellites, an anomaly that CEO Elon Musk says will need a “thorough investigation”.

After a rare last-second launch abort on March 15th and a three-day range-related delay, Falcon 9 booster B1048 lifted off with 60 upgraded Starlink v1.0 satellites on its fifth orbital-class mission. At least for the first two and half minutes, the booster performed precisely as intended, carrying a fueled upper stage and its ~16 metric ton (36,000 lb) payload to an altitude of 55 km (34 mi) and a velocity of 1.8 km/s (1.1 mi/s). However, about 10 seconds before the booster reached main engine cut-off (MECO) and stage separation, something went wrong.

While there is some ambiguity in his response, according to Musk, at least one of Falcon 9 B1048’s nine Merlin 1D engines performed an early shutdown before MECO. The rocket’s computer immediately accounted for the anomaly, extending the remaining eight-engine booster burn 5-7 seconds beyond the nominal timeline to ensure mission success. While the booster’s loss is still disappointing and the premature engine shutdown more than a little concerning, it’s critical to remember that mission success was ensured. Just 15 minutes after liftoff, the rocket’s upper stage successfully spun up and deployed another 60 Starlink satellites, bringing SpaceX’s operational constellation to an incredible ~350 satellites.

Based on live views available from SpaceX’s launch webcast, it appears that Falcon 9’s “early engine shutdown” is more of a euphemism for a fairly violent engine failure that triggered an instantaneous cutoff, preventing damage elsewhere. While SpaceX would certainly rather avoid in-flight engine failures, Falcon 9’s nine Merlin 1D booster engines are installed inside an aluminum ‘octaweb’ structure that transmits their thrust to the rest of the rocket but also effectively quarantines each engine in a blast-proof bunker.

Despite the partial failure, Falcon 9 B1048 continued to fight its way through its landing trajectory until it either ran out of propellant or burnt up during reentry. (SpaceX)

Nevertheless, the rocket’s highly-attuned software and affected octaweb engine bunker did their jobs, instantly shutting the failing engine down while also preventing the explosion and resulting shrapnel from damaging the rest of the rocket. More likely than not, B1048’s autonomous decision to always put mission success before booster recovery lead the booster to expend a majority of the propellant needed for its landing attempt to make up for the 10 or so seconds operating at only ~89% thrust.

As a result, B1048 may have simultaneous subjected itself to a much more extreme atmospheric reentry and run out of propellant before it could complete (or maybe even start) its drone ship landing burn. There’s also a chance that the engine that failed was one of the three engines required for reentry and landing burns, an asymmetry that would be impossible to overcome on the fly. Ultimately, the booster likely impacted the ocean at a near-supersonic velocity, smashing it into aluminum confetti. Thankfully, the late B1048 had a record-breakingly productive career as an orbital-class booster, placing dozens of tons of payload into orbit over five successful launches. Its loss is regrettable but the booster has more than earned its keep.

Aside from two twice-flown Falcon Heavy Block 5 side boosters of unknown status and 2-3 new boosters assigned to critical NASA and US Air Force missions, SpaceX’s fleet is now down to just three flightworthy Falcon 9 boosters. This could dramatically limit its options for near-term commercial flights, as none of those rockets – even assuming flawless launch and landing debuts – will likely be ready for their first reuses until May or June. Meanwhile, B1051 and B1049 have three and four missions under their respective belt and both completed their last launches just 50-70 days ago, while B1059 flew for the second time just two weeks ago. Despite the fact that it successfully completed its fifth mission, B1048’s in-flight engine failure will almost certainly delay upcoming launches, although the degree of those delays is up for debate.

Up next for SpaceX is SAOCOM 1B, an Argentinian radar satellite set to become the first payload launched into a polar orbit from the US East Coast in half a century. Before B1048’s anomaly, the mission was scheduled to launch no earlier than March 30th and could use any of unassigned boosters described above

Elon Musk reiterates rapid Starship V3 timeline with next launch in sight

Musk shared the update in a brief post on X, writing, “Starship flies again next month.”

Elon Musk has confirmed that Starship will fly again next month, reiterating SpaceX’s aggressive timeline for the first launch of its Starship V3 rocket.

Musk shared the update in a brief post on X, writing, “Starship flies again next month.” The CEO’s post was accompanied by a video of Starship’s Super Heavy booster being successfully caught by a launch tower in Starbase, Texas. 

The timeline is notable. In late January, Musk stated that Starship’s next flight, Flight 12, was expected in about six weeks. This placed the expected mission date sometime in March. That estimate aligned with SpaceX’s earlier statement that Starship’s 12th flight test “remains targeted for the first quarter of 2026.”

If the vehicle does indeed fly next month, it would mark the debut of Starship V3, the upgraded platform expected to feature the rocket’s new Raptor V3 engines.

Raptor V3 is designed to deliver significantly higher thrust than earlier versions while reducing cost and weight. Starship V3 itself is expected to be optimized for manufacturability, a critical step if SpaceX intends to scale production toward frequent launches for Starlink, lunar missions, and eventually Mars.

Starship V3 is widely viewed as the version that transitions the program from experimental testing to true operational scaling. Previous iterations have completed multiple integrated flight tests, with mixed outcomes but steady progress. Expectations are high that SpaceX is now working on Starship’s refinement.

An aggressive launch schedule supports several priorities at once. It advances Starlink’s next-generation satellite deployment, supports NASA’s lunar ambitions under Artemis, and keeps SpaceX on track for its longer-term Moon and Mars objectives.

Tesla’s six-seat, extended-wheelbase Model Y L has been approved for sale in Australia, as per newly published government documents.

The variant, listed as YL5NDB on the Australian government’s ROVER approval website, has confirmed that Tesla has received regulatory clearance to offer the extended Model Y to domestic customers.

Documents seen by Drive show that the Model Y L has been approved in Australia in a single dual-motor, all-wheel-drive configuration. While Tesla has not formally announced a launch date, vehicles are typically approved for Australian sale several months before arriving in showrooms.

The Model Y L is a longer version of the regular Model Y, designed to accommodate a six-seat layout with two seats in each row. It measures 177mm longer overall than the regular Model Y, at 4969mm, and features a 150mm longer wheelbase at 3040mm.

Australian approval documents list the Model Y L with the same nickel-manganese-cobalt battery pack used in the regular Model Y Long Range, which is expected to have a gross capacity of about 84kWh and a usable capacity of about 82kWh. Output is officially listed at 378kW in government filings, though real-world peak output may differ.

The Model Y L replaces the regular Model Y’s second-row bench with two captain’s chairs featuring heating, ventilation, and power adjustment. Heated third-row seats are also included.

Additional upgrades reported by Drive include an 18-speaker sound system, new front seats with single-piece backrests, and continuously variable shock absorbers. The only wheel option listed for the Australian model is 19-inch wheels.

In Europe, where the Model Y L has also received approval but has not yet launched, the variant is expected to claim up to 681km of WLTP range.

Tesla’s Full Self-Driving (Supervised) is able to recognize and respond to hand signals, as highlighted recently by CEO Elon Musk.

In his post on X, Musk wrote, “Tesla self-driving now recognizes hand signals.”

Musk shared the update in a quote reply to a video posted by Tesla Europe, which showed a vehicle operating with Full Self-Driving (Supervised) navigating a tight lane in the Netherlands while responding to hand gestures from a person directing traffic.

Hand signal recognition is an important capability for advanced driver-assistance and autonomous systems. In real-world driving, pedestrians, construction workers, parking attendants, and other drivers frequently use hand gestures to direct traffic, yield right of way, or indicate when it is safe to proceed. For a self-driving system operating in mixed environments, interpreting these non-verbal cues is critical.

Musk’s post comes as Tesla owners have surpassed 8 billion cumulative miles driven with FSD (Supervised) engaged. “Tesla owners have now driven >8 billion miles on FSD Supervised,” the company wrote in a post on X.

Annual FSD (Supervised) miles have increased sharply over the past five years. Roughly 6 million miles were logged in 2021, followed by 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. 

In the first 50 days of 2026 alone, Tesla owners logged another 1 billion miles. At the current pace, the fleet is trending toward approximately 10 billion FSD (Supervised) miles this year.

Tesla’s latest North America safety data, covering all road types over a 12-month period, also indicates that vehicles operating with FSD (Supervised) were recorded one major collision every 5,300,676 miles. By comparison, the U.S. average during the same period was one major collision every 660,164 miles.
