SpaceX is set to take another stab at the first integrated static fire test of Falcon Heavy Block 5 rocket, a milestone that will open the doors for its commercial launch debut just a handful of days later.

The window for the second Falcon Heavy’s static fire test will open at 10am EDT on Friday, April 5th and lasts until 7pm EDT (14:00-23:00 UTC), after which SpaceX engineers will likely spend a minimum of 24-48 hours analyzing the data produced and verifying the rocket’s health. Soon after, the rocket will be brought horizontal and rolled back into Pad 39A’s main hangar, where the payload fairing – containing the Arabsat 6A communications satellite – will be installed atop Falcon Heavy’s second stage before the rocket rolls back out to the pad for launch.

If all goes well during these relatively routine procedures, SpaceX can be expected to announce a date for Falcon Heavy’s second-ever launch, likely no sooner than 4-5 days after the static fire is completed. In other words, a flawless performance tomorrow could permit a launch date as early as April 9-10. Launching fewer than four days after completing static fire testing is rare even for Falcon 9, which has the luxury of far less complexity (and data produced) relative to Falcon Heavy, which has only flown once and is will attempt its second launch in a significantly different configuration.

Three months after Falcon Heavy’s February 2018 debut, SpaceX debuted Falcon 9 in its upgraded Block 5 configuration, featuring widespread changes to avionics, software, structures, thermal protection, and even uprated thrust for its Merlin engines. Falcon Heavy Flight 1 was comprised of Block 2 and Block 3 variants of the Falcon 9’s umbrella V1.2 Full Thrust configuration, which debuted in December 2015. Both side boosters – Block 2s – were flight-proven and had previously launched in 2016, while the rocket’s heavily modified center core was effectively a new version of Falcon 9 based on Block 3 hardware.

One of the biggest goals of Block 5 / Version 6 is ease of reusability. In principle we could re-fly Block 4 probably upwards of ten times, but with a fair amount of work between each flight. The key to Block 5 is that it’s designed to do ten or more flights with no refurbishment between each flight. Or at least no scheduled refurbishment between each flights. The only thing that needs to change is you reload propellant and fly again.

And we have
upgrades to all the avionics as well. So we have an upgraded flight computer, engine controllers, a … more advanced inertial measurement system. [Block 5 avionics are] lighter, more advanced, and also more fault-tolerant. So it can withstand a much greater array of faults than the old avionics system. [They’re] better in every way.

Block 5 has improved payload to orbit. Improved redundancy. Improved reliability. It’s really better in every way than Block 4. I’m really proud of the SpaceX team for the design.


– SpaceX CEO Elon Musk, May 2018

A different different rocket

Given just how extensive the changes made with Block 5 are, Falcon Heavy Flight 2 is drastically different than its sole predecessor, emphasized by the 13+ months SpaceX has taken to go from Flight 1 to Flight 2. Had SpaceX been able to successfully recover Falcon Heavy’s first center core (B1033) after launch, its quite likely that the company would have attempted to refly the rocket’s three landed boosters a bit sooner than April 2019, but the booster’s failed landing threw a bit of a wrench in the production plan.

After intentionally expending almost a dozen recoverable Block 3 and 4 Falcon 9 boosters in 2017 and 2018, SpaceX’s fleet of flightworthy cores had been reduced to a tiny handful. Interrupting Falcon 9 Block 5’s production ramp would have likely become a bottleneck for 2018’s launch cadence, and may well have contributed to SpaceX falling short from its planned 30 and then 24 launches last year with a still-impressive 21. Building an entirely new Falcon Heavy center core was simply not a priority as SpaceX required all production hands on deck to build enough Block 5 boosters to avoid major launch delays.

As a result, SpaceX delayed the production of the first Falcon Heavy Block 5 center core by ~6 months and ~8 boosters, shipping the rocket – presumed to be B1055 – to McGregor, Texas for static fire acceptance testing in Q4 2018. The center core arrived in Florida in mid-February 2019, following both side cores and a payload fairing.

Ultimately, SpaceX is likely to conduct Falcon Heavy’s first commercial launch with about as much caution as could be observed during the unique launches of SSO-A (the first triple-reflight of a Falcon 9), Crew Dragon DM-1 (stringent NASA oversight), and GPS III SV01 (stringent USAF oversight), as well as Falcon Heavy’s original launch debut. All four missions took anywhere from one to three weeks to go from a successful static fire to launch. Falcon Heavy Flight 2 will likely be similar, although a much faster turnaround is undeniably within the realm of possibility. For Falcon 9 Block 5, SpaceX’s current record stands at three days, achieved twice in ten Block 5 launches.

Stay tuned for an official SpaceX confirmation of Falcon Heavy’s second integrated static fire, as well as new launch date.

Elon Musk pivots SpaceX plans to Moon base before Mars

The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.

Elon Musk has clarified that SpaceX is prioritizing the Moon over Mars as the fastest path to establishing a self-growing off-world civilization. 

The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.

Why the Moon is now SpaceX’s priority

In a series of posts on X, Elon Musk stated that SpaceX is focusing on building a self-growing city on the Moon because it can be achieved significantly faster than a comparable settlement on Mars. As per Musk, a Moon city could possibly be completed in under 10 years, while a similar settlement on Mars would likely require more than 20.

“For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars,” Musk wrote in a post on X.

Musk highlighted that launch windows to Mars only open roughly every 26 months, with a six-month transit time, whereas missions to the Moon can launch approximately every 10 days and arrive in about two days. That difference, Musk stated, allows SpaceX to iterate far more rapidly on infrastructure, logistics, and survival systems.

“The critical path to a self-growing Moon city is faster,” Musk noted in a follow-up post.

Mars still matters, but runs in parallel

Despite the pivot to the Moon, Musk stressed that SpaceX has not abandoned Mars. Instead, Mars development is expected to begin in about five to seven years and proceed alongside the company’s lunar efforts.

Musk explained that SpaceX would continue launching directly from Earth to Mars when possible, rather than routing missions through the Moon, citing limited fuel availability on the lunar surface. The Moon’s role, he stated, is not as a staging point for Mars, but as the fastest achievable location for a self-sustaining off-world civilization.

“The Moon would establish a foothold beyond Earth quickly, to protect life against risk of a natural or manmade disaster on Earth,” Musk wrote.

SpaceX has acquired an aerospace business from Hexagon Purus ASA in a deal worth up to $15 million. The deal adds composite pressure vessel expertise to SpaceX’s growing in-house supply chain.

As per Hexagon Purus ASA in a press release, SpaceX has agreed to purchase its wholly owned subsidiary, Hexagon Masterworks Inc. The subsidiary supplies high-pressure composite storage cylinders for aerospace and space launch applications, as well as hydrogen mobility applications. Masterworks’ hydrogen business is not part of the deal. 

The transaction covers the sale of 100% of Masterworks’ shares and values the business at approximately $15 million. The deal includes $12.5 million in cash payable at closing and up to $2.5 million in contingent earn-out payments, subject to customary conditions and adjustments.

Hexagon Purus stated that its aerospace unit has reached a stage where ownership by a company with a dedicated aerospace focus would best support its next phase of growth, a role SpaceX is expected to fill by integrating Masterworks into its long-term supply chain.

The divestment is also part of Hexagon Purus’ broader portfolio review. The company stated that it does not expect hydrogen mobility in North America to represent a meaningful growth opportunity in the near to medium term, and that the transaction will strengthen its financial position and extend its liquidity runway.

“I am pleased that we have found a new home for Masterworks with an owner that views our composite cylinder expertise as world-class and intends to integrate the business into its supply chain to support its long-term growth,” Morten Holum, CEO of Hexagon Purus, stated.

“I want to sincerely thank the Masterworks team for their dedication and hard work in developing the business to this point. While it is never easy to part with a business that has performed well, this transaction strengthens Hexagon Purus’ financial position and allows us to focus on our core strategic priorities.”
