SpaceX Falcon Heavy rocket still on track for two launches this year

Published

Spaceflight Now reports that SpaceX’s next two Falcon Heavy rockets – both under contract with the US military – are scheduled to launch as early as July and October 2021.

Known as USSF-44 and USSF-52, both missions will see Falcon Heavy rockets launch unknown US military satellites – one directly to a circular geostationary orbit (GEO) and the other to an elliptical geostationary transfer orbit (GTO). The nature and purpose of those satellites will likely remain a mystery up to and after both launches, though their target and destination orbits may allow independent satellite tracking fans to loosely speculate, at minimum.

SpaceX has already shipped all three of USSF-44’s new Falcon Heavy boosters from its Hawthorne, California factory to McGregor, Texas test facilities. At least one of those boosters has also completed static fire acceptance testing in Texas and been delivered to SpaceX’s Florida facilities. Outfitted with a telltale nosecone, that side booster will likely be joined by its twin within the next few weeks – if it hasn’t already.

According to a US military spokesperson that responded to Spaceflight Now’s inquiries, Falcon Heavy’s USSF-44 launch has apparently slipped from a target of “late spring” to no earlier than (NET) July 2021 – a delay of a few weeks to one or two months. Although SpaceX still has two twice-flown Falcon Heavy Block 5 side boosters on hand from the rocket’s back-to-back April and June 2019 launches, the US military requested all new boosters for USSF-44.

Notably, the same official revealed that SpaceX and the US military are targeting October 2021 for Falcon Heavy’s USSF-52, just three months after USSF-44. USSF-44 will be Falcon Heavy’s first launch in an expendable-center-core configuration, meaning that one of the rocket’s three boosters will be intentionally expended. That means that SpaceX will need to complete, test, and deliver another new Falcon Heavy center core before USSF-52 can launch.

SpaceX has spent at least 2-3 months testing each new Falcon booster in McGregor over the last year or so, meaning that it would require a major boost in processing cadence to deliver six new boosters in just 6-8 months. In other words, barring several months of delays, it’s likely that SpaceX and the USSF are currently planning for USSF-52 under the assumption that it will reuse the Falcon Heavy side boosters from USSF-44 or from the rocket’s second and third launches.

Regardless, tentative July and October launch targets make it more likely than not that SpaceX will be able to launch Falcon Heavy twice this year even if booster production, testing, or processing take a bit longer than expected and both missions run into minor delays on the launch pad. USSF-44 will be Falcon Heavy’s first launch in more than two years, a lengthy delay between flights that appears to be unlikely to happen again as SpaceX continues to fill the rocket’s manifest with no fewer than eight launches between now and the end of 2024.

The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.

According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.

The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring. 

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.

The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.  

ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.

“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.

“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade

Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.

Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.

Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.

Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error. 

More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report. 

Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.

Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.

Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.

“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
