As the four astronauts of NASA’s Artemis II mission continue their record-setting journey farther into the cosmos than any human has gone before, a conspicuous silence from SpaceX and its CEO Elon Musk has become a story in itself. Four days after the historic April 1 launch from the Kennedy Space Center—which saw over 400,000 spectators gather in Cape Canaveral and more than 17 million views on YouTube—the space community is buzzing not just about the success of the lunar flyby, but about the notable absence of public praise from the head of America’s most prominent commercial rival . While the world watched NASA’s Space Launch System (SLS) rocket roar to life at 6:35 p.m. ET, carrying astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Jeremy Hansen toward the Moon, Musk’s social media platform X (formerly Twitter) remained devoid of the congratulatory messages that typically flow from the industry following a major achievement .
Theories regarding Musk’s muted response have coalesced around a specific point of tension: NASA’s controversial decision to terminate SpaceX’s $4.4 billion contract for the Artemis III mission in October 2025. Citing significant developmental delays with the Starship—the massive, fully reusable rocket designed for lunar landings and eventual Mars colonization—the space agency reopened the bidding for the critical landing system . This decision, which handed a major logistical role back to NASA’s internal systems and traditional contractors, represents a stunning reversal for a company that had become synonymous with routine, cost-effective access to space. Aerospace engineer Christopher David, whose social media posts have gone viral this week, offered a blunt assessment of the situation. “Yes. They’re jealous,” David wrote, responding to a query about the silence from the “Tesla/SpaceX Twittersphere” . He elaborated on a prediction he made five years ago, arguing that the fundamental engineering of the Starship poses insurmountable hurdles. “Starship will never make it into orbit. It’s too heavy. Both stages can’t be reusable and still be able to put an appreciable payload into LEO,” he stated, suggesting that watching NASA succeed with the traditional, heavy-lift SLS rocket—built by Boeing and Northrop Grumman—might be a bitter pill for the commercial innovator to swallow .
However, the situation is more nuanced than simple professional jealousy. Musk has always positioned SpaceX not just as a contractor, but as the vanguard of a new space age where rockets are as reusable as airplanes. In July 2024, he confidently claimed that Starship offers a path to far greater payload to the Moon than the Artemis program currently anticipates . With Artemis II proving that the Orion capsule and SLS can safely carry humans—a milestone SpaceX has yet to achieve with Starship—the silence may reflect a strategic recalibration rather than mere pique. Industry observers note that April 1 also marked the day SpaceX began its initial public offering (IPO) process, a massive financial event that demands strict compliance with “quiet period” regulations . Publicly disparaging or even over-praising a government client during a stock launch could invite legal scrutiny, though this does not entirely explain the absence of even a perfunctory “congratulations” from a user known for unfiltered commentary.
Meanwhile, the Artemis II crew continues to execute their mission flawlessly. Having successfully completed proximity operations in Earth orbit to test the Orion capsule’s maneuvering capabilities, the crew is scheduled to perform the critical translunar injection burn to slingshot toward the Moon . As of today, April 5, the astronauts are preparing for the closest phases of their lunar encounter. NASA’s schedule indicates that on April 6, the crew will surpass the record for the farthest distance from Earth, breaking the 248,655-mile record set by Apollo 13 in 1970 . The agency is providing 24/7 coverage of the event, though public reaction to the broadcast has been mixed, with some viewers comparing NASA’s production quality unfavorably to SpaceX’s highly polished, real-time data-rich streams .
The silence from SpaceX is amplified by broader political and scientific reactions to the mission. While President Donald Trump took time during a national address to praise the “brave astronauts” and call the launch “amazing,” other prominent voices in the scientific community have expressed restraint . Writing in Nature prior to the launch, some researchers articulated a disconnect between the engineering spectacle and the scientific yield of a crewed flyby. Planetary geochemist Marc Norman of Australian National University offered a tempered perspective on the mission’s scientific value. “A fly-by makes sense to demonstrate the systems before attempting a landing… I’m not especially excited at this stage,” he said . Similarly, Yarrow Axford, a paleoclimatologist, pointed to the difficult context of the mission, noting that cuts to NASA’s science budgets and internal layoffs have dampened morale. “Leading scientists have been leaving NASA, along with other federal science agencies, in droves,” she noted .
As the Orion spacecraft pushes toward the lunar sphere of influence, the silence from Elon Musk remains the most dramatic subtext of the mission. NASA Administrator Jared Isaacman has framed the launch as a definitive statement of American capability, stating, “NASA is back in the business of sending people to the Moon” . Yet, the absence of a nod from the industry’s most famous billionaire highlights the fragmented nature of modern space exploration—a field no longer dominated by a single national effort but by a competitive, and sometimes resentful, collection of public and private giants. With Artemis IV aiming for a lunar landing in 2028 and SpaceX’s Starship still in development, the race to determine who will carry the flag for humanity’s return to the surface is far from over .
