SpaceX ships Mars engine to Texas for testing

Published

The foundation of any space program is the rocket engines that lift people and payloads off the ground and send them on their way to distant destinations, whether the target is the International Space Station, the moon, or Mars. To date, SpaceX has relied upon its Merlin rocket engine to power its space missions.

But Elon Musk has larger goals for SpaceX than putting satellites into orbit or ferrying astronauts to the ISS. His ultimate plan is to establish a human colony on Mars. That will require more powerful rockets than the Merlin engines used for today’s space missions.

Musk says the next generation Raptor engine is three times more powerful than the Merlin and will generate up to 500,000 lbs of thrust. A cluster of nine Raptor engines will be used to lift the Mars Colonial Transporter on its way to the Red Planet.

This week, SpaceX president Gail Shotwell told the Small Satellite Conference held in Logan, Utah that a Raptor engine has been shipped to the company’s test site in MacGregor, Texas.

Aerospace engineers say it usually takes five to seven years to develop a new rocket engine. Full scale engine testing typically takes place toward the end of the development process. If testing of the Raptor is about to begin, that suggests SpaceX is on target to send a manned Dragon spacecraft to Mars as early as 2020. SpaceX has already successfully demonstrated the supersonic retro-rocket technology it will need to land the Dragon capsule on Mars.

Musk says he will unveil more details about how SpaceX will colonize Mars at this year’s International Astronautical Conference in Guadalajara, Mexico scheduled for September 26 this year. He is often criticized for setting time tables that are overly optimistic, but if testing of the Raptor engine is about to get underway, that would indicate the Mars colonization program is right on time.

SpaceX blocks unauthorized Starlink terminals used by Russian troops

Ukrainian officials confirmed that Starlink terminals believed to be used by Russian troops were disabled after coordination with SpaceX.

SpaceX has taken steps to block unauthorized use of its Starlink satellite internet network, a move Ukrainian officials stated is already disrupting Russian military communications. 

Russian units lose a key communications tool

As per a report from The Guardian, Ukrainian defense officials have confirmed that Starlink terminals believed to be used by Russian troops were recently disabled after coordination with SpaceX. The move reportedly affected frontline communications and drone operations, especially in areas where traditional military radios are unreliable or easily jammed.

For months, Russian units had relied on large numbers of illicitly obtained Starlink terminals to stay connected along the front. The satellite internet service allowed faster coordination and more precise drone use for Russian forces.

Several Russian military bloggers close to frontline units have acknowledged the impact of the Starlink shutdown, with some describing sudden connectivity problems in the satellite internet service.

Russia lacks comparable replacement

Russia does not have a satellite internet system that matches Starlink’s speed, coverage, and ease of deployment. Alternatives such as fiber-optic lines, short-range wireless links, and digital radio systems take longer to install and work inadequately for fast-moving units.

Russia does operate limited satellite communications through state-linked providers, but those systems rely mainly on geostationary satellites, which are notably slower. Coverage is uneven, and data capacity is far lower than Starlink’s low-Earth-orbit network.

For now, Ukraine has stated that it has introduced a verification system that allows only approved Starlink terminals to connect. Devices believed to be linked to Russian forces are blocked from the network. That being said, Ukrainian officials have also claimed Russian units are trying to work around the restrictions by asking civilians to register Starlink terminals in their names.

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 strengthens manufacturing base with Hexagon Purus aerospace deal

The deal adds composite pressure vessel expertise to SpaceX’s growing in-house supply chain.

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.”
