The first commercial launch of SpaceX’s Falcon Heavy rocket – this time in a Block 5 configuration – is as few as ten days away from a targeted window beginning at 6:36 pm EST (22:36 UTC), April 7th. That target hinges on whether Falcon Heavy is ready and able to roll out to Pad 39A and successfully conduct its first integrated static fire, currently scheduled on April 1st.

The payload for this mission – communications satellite Arabsat 6A – had its original Lockheed Martin manufacturing and SpaceX launch contracts signed back in the first half of 2015, while the 6000 kg (13,200 lb) spacecraft was effectively completed once it was shipped from California to Florida at the start of 2019. After approximately 12 months of delays from an original launch target shortly after Falcon Heavy’s 2018 debut, Arabsat 6A’s four-year journey will hopefully reach completion in a geostationary transfer orbit. At the same time, the US Air Force says that it will be watching this launch – and the one meant to follow soon after – as a critical test along the path to fully certifying the powerful rocket for military launches.

As a pathfinder for an unproven rocket, SpaceX’s first Falcon Heavy launch suffered a number of likely minor to moderate anomalies as company engineers and technicians learned for the first time how the rocket actually behaves in the real world, under real-world conditions and operations. Case in point, the first integrated Falcon Heavy was taken through its first wet-dress rehearsal – in which the vehicle is filled with a flight load of fuel and oxidizer – on January 11th. An anomaly required additional work and took nearly two weeks to resolve, culminating in the rocket’s first (and successful) static fire on January 24th. An additional two weeks after that, SpaceX went ahead with the first attempted launch of Falcon Heavy with great success, pushing the T-0 back several hours due to weather but ultimately completed an almost flawless debut, aside from an anomaly that caused the center core to impact the ocean surface at high speeds.

Despite the invaluable experience gained by those orchestrating the launch and those who built the vehicle, Falcon Heavy’s second launch may result in similar teething pains, particularly due to the fact that the rocket’s complete upgrade to Block 5 hardware likely necessitated significant design changes across the board. In other words, the rocket SpaceX aims to launch in early April may be quite a bit different from the vehicle that launched 14 months prior, creating much of the same uncertainty inherent in the first launch(es) of any new rocket. Still, many of the complex boosters’ connection and separation mechanisms that were flight-tested for the first time that February were likely more or less unchanged in the move from Block 2/3 to Block 5 hardware.

“Again, I don’t want to tempt fate. But this is a much stronger octaweb structure. It’s made of a much higher strength of bolted aluminum. A 7000 series instead of a 2000 series. So the strength of the octaweb is dramatically greater. It also has quite a bit of thermal protection in case there’s say, an engine fire, or something like that. Such that it does not melt the octaweb.” – SpaceX CEO Elon Musk, May 2018

“Biggest process change [for Block 5] was eliminating Tig welding of the thrust structure or “Octaweb” and the move to a bolted design but this made it much easier and faster to produce overall as well.” – SpaceX VP of Production Andy Lambert, April 2018

A step further, SpaceX CEO Elon Musk has indicated that one major section of Block 5 upgrades – moving from a welded to a bolted thrust structure (i.e. octaweb) – was expected to be a boon for Falcon Heavy, while also making octawebs far easier to manufacture, assemble, and even disassemble. According to Musk, new bolted octawebs are also “dramatically” stronger, a boon for Falcon Heavy boosters – particularly the center core – that need to survive forces multiple times stronger than those subjected upon Falcon 9 first stages.

Meanwhile, according to comments made by Air Force officials to Spaceflight Now, the USAF is looking at SpaceX’s Arabsat 6A and subsequent STP-2 Falcon Heavy launches as critical steps along the way to fully certifying the rocket for valuable military payloads. Currently, the only option available for military and NRO payloads past a certain weight or in need of exceptionally high-energy orbits is ULA’s Delta IV Heavy rocket, an extremely expensive ($300M+ per launch) rocket with a bad track record of schedule reliability.

An Air Force spokesperson this week confirmed the agreement to use previously-flown side boosters for the STP-2 mission. The center core will be new for the Arabsat 6A and STP-2 launches.

“This provides an early opportunity for the Air Force to understand the process for using previously-flown hardware with the goal to open future EELV missions to reusable launch vehicles,” the spokesperson said in response to an inquiry from Spaceflight Now.

Given that STP-2 will need to reuse both of the Arabsat 6A Falcon Heavy’s side boosters, the USAF official also specifically noted that the military branch would be examining SpaceX’s refurbishment processes and the performance of the flight-proven stages with the intention of ultimately allowing reused rockets to launch military satellites. As such, the successful launch, landing, refurbishment, and re-launch of both Falcon Heavy side boosters (B1052 & B1053) will be doubly critical for SpaceX.

SpaceX pitches subscription model for Trump’s Golden Dome

SpaceX pitched a subscription model for Trump’s Golden Dome. Faster deployment, but at the cost of gov control & steady bills.

SpaceX pitched a subscription model for U.S. President Donald Trump’s Golden Dome for America.

SpaceX is a frontrunner to build key components of President Trump’s Golden Dome–formerly known as the Iron Dome. In January, President Trump signed an Executive Order to build an Iron Dome missile defense shield to protect America.

The ambitious project has drawn intense interest from defense startups, including Epirus, Ursa Major, and Armada. Companies with long-standing contracts with the U.S. government are also vying to build Trump’s Golden Dome, like Boeing and Lockheed Martin.

According to six Reuters sources, SpaceX is partnering with Palantir and Anduril on a Golden Dome proposal for the U.S. government.

The trio is pitching a plan to deploy 400 to 1,000+ satellites for missile detection and tracking, with a separate fleet of 200 attack satellites armed with missiles or lasers to neutralize threats. SpaceX will mainly focus on the sensing satellites, not weaponization.

SpaceX reportedly proposed a subscription service model for Trump’s Golden Dome, where the government pays for access rather than owning the system outright. This approach could bypass some Pentagon procurement protocols, enabling faster deployment. However, it risks locking the government into ongoing costs and reduced control over development and pricing.

A few Pentagon officials are concerned about SpaceX’s subscription model for the Golden Dome because it is a rare approach for major defense programs. U.S. Space Force General Michael Guetlein is exploring whether SpaceX should own and operate its segment or if the U.S. should retain ownership with contractors managing operations.

The Golden Dome’s innovative scope and SpaceX’s subscription model signal a new era for defense contracting. However, Trump’s Golden Dome program is in its early stages, giving the Pentagon time to consider SpaceX’s subscription model proposal. As the Pentagon weighs options, SpaceX’s technical prowess and unconventional approach position it as a key player in Trump’s vision for a robust missile shield.

Bell Canada takes aim at potential Starlink subsidies

Tensions are rising in Canada’s telecommunications landscape as the nation’s leading telecom provider, Bell Canada, seeks to block Elon Musk’s Starlink from accessing potential subsidies.

Details of Bell Canada’s anti-Starlink efforts were shared by the Financial Times (FT).

Bell’s Push to Block Starlink Subsidies

As noted by the FT, Bell Canada and its subsidiary Northwestel are lobbying against potential subsidies that Starlink could receive for providing internet access to the country’s remote northern regions, including the Arctic. In correspondence obtained by the Times, Bell argued that Starlink’s flat pricing proves that it does not require support to operate in Canada’s remote areas. 

A decision about the matter will be announced by the Canadian Radio-television and Telecommunications Commission (CRTC). That being said, the CRTC stated in January that a subsidy would help make “internet services more reliable and affordable for residents of the Far North.”

Starlink’s Defense

SpaceX, Starlink’s parent company, has fired back at Bell, stating that blocking subsidies would harm competition and leave isolated communities such as First Nations groups with fewer, more expensive, and less reliable internet options.

While Canada’s two biggest telecommunications groups, Bell and Rogers, still dominate the country’s internet and phone service market, Starlink has been making progress in its efforts to saturate the country’s remote regions. Starlink received official approval to operate in October 2022, and since then, it has grown its customer base to 400,000 active customers as of last year.

Musk’s Empire Under Fire in Canada

The subsidy clash is part of a broader Canadian backlash against Musk’s ventures, which seems to be fueled by his role in the Trump administration. Apart from Bell’s anti-Starlink efforts, Ontario also axed a $100 million Starlink contract. Quebec has noted that it would not be renewing its Starlink subsidy scheme as well. 

Tesla, on the other hand, lost government EV subsidies, with Transport Minister Chrystia Freeland leading the charge. As per Geoff White of the Public Interest Advocacy Center, “We should not be giving one cent of public money to an unaccountable imperialist like Elon Musk.”

A few days ago, Tesla announced that the first Megapack battery units from its Shanghai “Megafactory” were being shipped to Australia.

As per recent reports, the massive grid-scale Tesla batteries are bound for Queensland’s Western Downs battery project.

The Shanghai Megafactory

The Shanghai Megafactory is Tesla’s first battery storage factory outside the United States. Built close to Gigafactory Shanghai, the Shanghai Megafactory is expected to supply Megapack batteries to both China and foreign markets.

The Megapack represents a huge portion of Tesla Energy’s deployments. With 3.9 MWh of energy, Tesla notes that each Megapack is enough to power 3,600 homes for an hour. The Shanghai Megafactory has a capacity to produce 10,000 Megapacks per year to start. 

Mike Snyder, vice president of Tesla, shared his optimism about the Shanghai Megafactory. “Megafactory gives us the ability to scale production and efficiency. We can lower logistics costs as well as product costs, and grow the business to new markets,” he stated.

Australia Battery Projects

As noted in a report from Renew Economy, the first Megapack shipments from the Shanghai Megafactory will be installed in the second stage of the Western Downs battery project, which is being built by Neoen. The Western Downs battery project involves a 460 MWp solar farm coupled with a 540 MW/1,080 MWh big battery system.

Tesla has also been listed as the battery supplier for the upcoming Calala battery in Tamworth, New South Wales, which will involve 138 Megapack units. The Megapacks for the Calala battery will likely be imported from the Shanghai Megafactory as well.

Data from Rosetta Analytics suggests that Tesla is currently the dominant player in Australia’s energy storage segment, with the company holding over 30% of the market. Tesla has become a notable presence in Australia’s energy sector for years, especially following the company’s buildout of the Hornsdale “big battery,” which was initially comprised of Tesla Powerpacks, in 2017.
