SpaceX CEO Elon Musk says that the company’s first full-scale Starship prototype has completed an inaugural hop test in South Texas, igniting its lone Raptor engine and straining against a trio of tethers attached to its legs.

While relatively minor in the scope of SpaceX’s next-generation rocket program, Starhopper’s successful tethered hop now paves the way towards untethered testing in which the terminally suborbital testbed could spend several minutes aloft and reach altitudes as high as 5 km (3 mi). Aside from Starhopper itself, this perhaps marks an even more significant milestone for Raptor, completing the engine’s first successful test-fire as part of an integrated flight vehicle.

Starhopper’s first successful Raptor ignition comes after the better part of two weeks of concerted testing of the integrated prototype, beginning around March 18/19. That testing included 5+ wet dress rehearsals (WDRs) that involved loading the vehicle with a significant quantity of liquid methane and oxygen propellant, verifying the performance of avionics and plumbing, and ultimately attempting to ignite Raptor.

Ironically, less than 24 hours before Starhopper’s successful ignition, SpaceX CEO Elon Musk had noted that the rough prototype, its ground systems, or both were suffering from issues caused by ice formation in propellant valves. Reading between the lines, it’s likely that the issues involved valves on both Starhopper and its ground support equipment ‘sticking’ (i.e. failing to actuate) when commanded. While not usually a particularly large risk for the overall health of the vehicle and pad, uncooperative valves will almost invariably throw a wrench in the gears of attempted rocket operations, particularly when dealing with cryogenic propellants like those used by Starhopper.

As the supercool methane and oxygen inevitably begin to warm after leaving the propellant plant and entering Starhopper’s tanks, a fraction of the liquid will gradually transition into gas and expand, requiring constant venting of the tanks to prevent overpressure events that could damage or destroy the rocket. Falcon 9 and Heavy exhibit this same behavior, as do most other liquid-fueled rockets. This helps to explain the massive venting seen throughout Starhopper’s half-dozen or so WDR tests, as well as large but routine fireballs as excess methane gas was burned off as part of the process of vehicle and pad pressure regulation.

According to Musk, “all systems [were] green” during Starhopper’s most critical test yet. If Raptor and its prototype host are still in good health after their integrated three-second ignition test, SpaceX could attempt several more static fires and tethered hops over the next few days, mirroring the extremely rapid test series observed in February with the first completed Raptor engine.

If all proceeds nominally, it’s possible that SpaceX could begin untethered hop tests in the near future. Regardless, this marks an excellent step forward for the company’s next-generation Starship/Super Heavy spaceship and launch vehicle – all data gathered in this phase will help to optimize and improve the final design of the first orbital vehicles.

Ukraine seeks Starlink alternatives from the EU

Ukraine is exploring EU satellite alternatives to Starlink, driven by concerns over Elon Musk’s unpredictability. Starlink remains vital for Ukraine’s battlefield connectivity and cannot be easily replaced. While the European Union has started developing Starlink alternatives, they have not quite reached SpaceX’s capacity to provide internet connection.

Starlink’s Critical Role and Vulnerabilities

Starlink’s 7,000+ satellite network provides essential connectivity for Ukraine’s military. However, SpaceX CEO Elon Musk’s influence has raised strategic concerns.

“Elon Musk is, in fact, the guardian of Ukraine’s connectivity on the battlefield. And that’s a strategic vulnerability,” warns Arthur De Liedekerke, Senior Director of European Affairs for Rasmussen Global.

Opinions of Musk have started to influence dealings with any of his companies, including SpaceX and Tesla. Starlink has not escaped criticism due to its relationship with Musk, resulting in a few governments seeking alternatives to SpaceX’s internet services.

For instance, the German military has announced plans to develop a Starlink alternative. Kyiv and the EU are also seeking options to reduce reliance on Starlink.

EU’s Govsatcom as a Near-Term Option

Member of the EU Parliament (MEP) Christophe Grudler pitched the European Union’s Govsatcom system as a viable alternative to Starlink for Ukraine.

“It is clear that if Starlink decides to cut the signal today, we have options, in particular with Govsatcom, which is the European network that we have brought into service and which, from June, will make it possible to supplement Starlink’s missing signal in Ukraine, if necessary,” he said.

Grudler affirmed: “The European Union is very committed to helping Ukraine, so there would certainly be agreement from all the Member States to come to Ukraine’s aid if it no longer had a Starlink signal in the future.”

However, De Liedekerke pointed out that GovSatcom was made for government use. He noted that “GoveSatcom is a governmental secure satellite communications and it’s essentially to provide reliable, secure, strategically autonomous networks for communication services between governments in the EU. It couldn’t replace the kind of battlefield connectivity that we’re discussing for Ukraine. So it’s not a silver bullet at the moment.”

Eutelsat’s Competitive Edge

Eutelsat, a Franco-British operator, offers a low-Earth orbit network with 630 satellites and 35 geostationary ones, though it trails Starlink’s scale. It has 2,000 terminals deployed in Ukraine and 14,000 more planned to deploy. Starlink has 40,000 terminals in Ukraine, used by the military and civilians.

Price is another factor to consider when seeking a Starlink alternative. Eutelsat’s €9,000 terminals are pricier than Starlink’s €500 units.

“Eutelsat is our European champion, one that has convincing functioning solutions. And one that we need to be able to support through funding and political will,” De Liedekerke said, noting its political independence from the U.S.

Iris2 as a Future Solution

The EU’s Iris2 project is another Starlink alternative Ukraine might consider. The Iris2 project is a 290-satellite constellation, promising secure, low-latency connectivity by 2030, with partial operations by 2028.

“From 2028, we will have an operational Iris2 constellation that will be able to provide telecommunications services to all the Member States that so wish. I would add that this will be the first time we have had a constellation secured with post-quantum cryptography, so cyber-attacks will not be possible on this constellation. It will be a world first with an ultra-secure signal, which is not the case with the Starlink signal either,” Grudler said. ‘

Led by the SpaceRISE consortium, Iris2 offers a long-term alternative, though its timeline limits immediate impact.

Strategic Diversification

De Liedekerke has stressed the need for options aside from Starlink.

“It’s about having options. It’s about not having a single point of failure. It’s being able to say no to one and still be online. And today, we’re not in a situation where we can do that. We’ve let Ukraine’s war zone connectivity be in the hands of one man…that’s a strategic vulnerability.

By having options, by having alternatives, by diversifying our partnerships, we avoid that single point of failure.”

Ukraine’s pursuit of EU solutions aims to ensure battlefield resilience. However, the EU has some way to go before it can match Starlink’s reach.

SpaceX pitches subscription model for Trump’s Golden Dome

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.”
