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.

Editor’s note: Corrected a passage that originally suggested that an “unmanned” Dragon would take flight in 2020 which in fact should be “manned”.

Starlink nears S Korea launch as satellite internet demand rises

Published

Starlink is poised to launch in South Korea this year, pending regulatory approvals, as global demand for low-orbit satellite connectivity surges.

On April 27, South Korea’s Ministry of Science and ICT announced system improvements to facilitate low-orbit satellite communication services like Starlink and the U.K.’s OneWeb. Low-orbit satellites, operating at 300–1,500 km, enable high-speed internet without extensive ground infrastructure, serving remote areas, ships, and airplanes.

“If we start domestic services, high-speed Wi-Fi services will be available on airplanes, and we will be able to provide online video services (OTT) and video calls to crews on long-haul ships,” said Minister of Science and ICT Yoo Sang-im.

According to KMIB, OneWeb is awaiting approvals for cross-border supply agreements and terminal suitability assessments. SpaceX’s Starlink is also waiting for approval. In October 2024, South Korea’s Ministry of Science and ICT notified the public about amendments to technical standards that would prevent frequent interference. After 60 days of the notice’s publication, the South Korean government is estimated to take 3-4 months to approve Starlink’s cross-board supply agreement with SpaceX.

Kim Nam-cheol, director of the Radio Policy Bureau, noted, “It is certain that (the two companies) will launch services this year, but it is difficult to specify a date as changes may occur during the consultation process.”

Starlink and OneWeb’s pending approvals in S. Korea involve ensuring compliance with local regulations, including terminal assessments for new devices. The push for satellite internet reflects a broader global trend, with S. Korea positioning itself to bridge connectivity gaps in aviation, maritime, and remote regions.

Starlink’s global reach is evident, and its usefulness increases as it expands. In January, T-Mobile used Starlink Cellular to transmit emergency alerts during LA wildfires. Meanwhile, Hawaiian and United Airlines offer Starlink Aviation for in-flight video streaming and gaming.

As Starlink expands, new competitors enter the ever-growing lob-orbit satellite communications industry. For example, Amazon’s Kuiper established a corporation in South Korea last May.

Starlink’s involvement in the Ukriane-Russia war has also led world governments to consider establishing their own satellite communications network. South Korea aims to develop its own independent satellite technology by 2030. The Asian nation plans to invest 320 billion won over six years to launch two communication units via the Nuri rocket.

Ukraine is also exploring Starlink alternatives developed by the European Union. In addition, Germany’s military, Bundeswehr, plans to build its own satellite constellation to reduce dependence on foreign networks amid geopolitical tensions.

As Starlink expands, S Korea’s regulatory and technological efforts could shape its role in the global satellite communication market, balancing foreign services with ambitions for domestic innovation.

SpaceX’s satellite internet venture Starlink has yet to secure an operating license in India. Starlink is facing regulatory delays in India despite ongoing progress.

India’s Telecom Minister Jyotiraditya Scindia confirmed that the company must meet stringent requirements before launching services in the country.

“The process is ongoing. The minute they meet all conditions — including setting up gateways in India and registering user terminals locally — we are ready to issue the license,” Scindia told local media.

The licensing process involves multiple agencies in India, including the Department of Telecommunications (DoT), the Telecom Regulatory Authority of India (TRAI), and the Indian National Space Promotion and Authorization Center (IN-SPACe). These agencies are evaluating Starlink’s compliance with India’s technical, administrative, and national security standards.

Scindia emphasized Starlink’s need for domestic registration of user terminals and local gateways to address data sovereignty and internal security concerns.

“It’s not only related to DoT but also to internal security — gateways have to be in India, any user terminal has to be registered in India…the minute they check all the boxes, which I also hope will be soon, the license should be given,” he added.

The requirements reflect India’s cautious approach to integrating foreign satellite providers into its telecom ecosystem. The delay comes amid broader industry calls for enhanced connectivity. At Mobile World Congress 2025 in Barcelona, Bharti Airtel chairman Sunil Mittal urged regulators to support telecom operators in closing the global connectivity gap for 400 million people, particularly in rural India. He advocated for resource sharing between terrestrial and satellite operators to avoid duplicative investments.

Bharti Airtel and Jio Platforms signed agreements with SpaceX to help expand Starlink services in India. The agreements are contingent on the Indian government approving Starlink’s license.

Starlink’s potential entry into India could bolster rural connectivity, but regulatory hurdles remain a significant barrier. As the company works to meet India’s conditions, its progress is closely watched by telecom operators and regulators alike. The outcome could shape the role of satellite internet in addressing India’s digital divide, aligning with global efforts to expand access through collaborative infrastructure investments.

SpaceX investment fuels Alphabet’s $8 billion profit surge

Alphabet Inc.’s first-quarter profit soared, boosted by an $8 billion unrealized gain from its investment in SpaceX. Since 2015, Alphabet has been a key SpaceX investor, joining Fidelity Investments to inject $1 billion for a 10% stake in the space firm.

The tech giant reported a 46% surge in net income to $34.54 billion, driven by strong advertising revenues and the SpaceX windfall, Bloomberg reported Thursday, citing a person familiar with the matter. SpaceX’s valuation hit approximately $350 billion in December, cementing its status as one of the world’s most valuable private companies. The company thrives on NASA contracts and its Starlink satellite internet service, which provides direct-to-consumer connectivity.

Unlike Tesla, SpaceX has largely sidestepped public backlash tied to CEO Elon Musk despite growing scrutiny. The Tesla Takedown movement, emboldened by Tesla’s first-quarter 2025 earnings, plans to target Musk’s other ventures, including SpaceX and Starlink.

Starlink faces its own challenges abroad. For instance, Ukraine is exploring Starlink alternatives developed by the European Union. Ukraine and EU member states have become increasingly worried about Elon Musk, which is being reflected in SpaceX’s Starlink contracts on the continent. However, Starlink remains critical for Ukraine’s battlefield connectivity, with EU alternatives lagging behind SpaceX’s robust internet capabilities.

Alphabet’s financial windfall underscores SpaceX’s growing influence in the space and satellite internet sectors. The $8 billion gain from “non-marketable equity securities,” identified as SpaceX, highlights the strategic value of Alphabet’s early investment. While Tesla grapples with public and activist scrutiny, SpaceX’s government contracts and Starlink’s consumer reach provide a buffer, though not immunity, from Musk-related controversies.
