The founder of Amazon, Jeff Bezos, does not often post on the social media site owned by his rival Elon Musk. But on Monday, Bezos did, sharing a black-and-white image of a turtle emerging from the shadows on X.

The photo, which included no text, may have stumped some observers. Yet for anyone familiar with Bezos' privately owned space company, Blue Origin, the message was clear. The company’s coat of arms prominently features two turtles, a reference to one of Aesop’s Fables, "The Tortoise and the Hare," in which the slow and steady tortoise wins the race over a quicker but overconfident hare.

Bezos' foray into social media turtle trolling came about 12 hours after Musk made major waves in the space community by announcing that SpaceX was pivoting toward the Moon, rather than Mars, as a near-term destination. It represented a huge shift in Musk's thinking, as the SpaceX founder has long spoken of building a multi-planetary civilization on Mars.

Launch Complex 39A at NASA's Kennedy Space Center in Florida is accustomed to getting makeovers. It got another one Wednesday with the removal of the Crew Access Arm used by astronauts to board their rides to space.

Construction workers first carved the footprint for the launch pad from the Florida wetlands more than 60 years ago. NASA used the site to launch Saturn V rockets dispatching astronauts to the Moon, then converted the pad for the Space Shuttle program. The last shuttle flight lifted off from Pad 39A in 2011, and the agency leased the site to SpaceX for use as the departure point for the company's Falcon 9 and Falcon Heavy rockets.

SpaceX started launching from Pad 39A in 2017, then installed a new Crew Access Arm on the pad's tower the following year, replacing the aging shuttle-era arm that connected to the hatches of NASA's orbiters. SpaceX added the new arm ahead of the first test flight of the company's human-rated Crew Dragon spacecraft in 2019. Astronauts started using the pathway, suspended more than 200 feet above the pad surface, beginning with the first crew flight on a Dragon spacecraft in 2020.

The National Labor Relations Board abandoned a Biden-era complaint against SpaceX after a finding that the agency does not have jurisdiction over Elon Musk's space company. The US labor board said SpaceX should instead be regulated under the Railway Labor Act, which governs labor relations at railroad and airline companies.

The Railway Labor Act is enforced by a separate agency, the National Mediation Board, and has different rules than the National Labor Relations Act enforced by the NLRB. For example, the Railway Labor Act has an extensive dispute-resolution process that makes it difficult for railroad and airline employees to strike. Employers regulated under the Railway Labor Act are exempt from the National Labor Relations Act.

In January 2024, an NLRB regional director alleged in a complaint that SpaceX illegally fired eight employees who, in an open letter, criticized CEO Musk as a “frequent source of embarrassment." The complaint sought reinstatement of the employees, back pay, and letters of apology to the fired employees.

The upgraded Super Heavy booster slated to launch SpaceX's next Starship flight has completed cryogenic proof testing, clearing a hurdle that resulted in the destruction of the company's previous booster.

SpaceX announced the milestone in a social media post Tuesday: "Cryoproof operations complete for the first time with a Super Heavy V3 booster. This multi-day campaign tested the booster's redesigned propellant systems and its structural strength."

Ground teams at Starbase, Texas, rolled the 237-foot-tall (72.3-meter) stainless-steel booster out of its factory and transported it a few miles away to Massey's Test Site last week. The test crew first performed a pressure test on the rocket at ambient temperatures, then loaded super-cold liquid nitrogen into the rocket four times over six days, putting the booster through repeated thermal and pressurization cycles. The nitrogen is a stand-in for the cryogenic methane and liquid oxygen that will fill the booster's propellant tanks on launch day.

As more than 120 million people tuned in to the Super Bowl for kickoff on Sunday evening, SpaceX founder Elon Musk turned instead to his social network. There, he tapped out an extended message in which he revealed that SpaceX is pivoting from the settlement of Mars to building a "self-growing" city on the Moon.

"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," Musk wrote, in part.

This is simultaneously a jolting and practical decision coming from Musk.

Welcome to Edition 8.28 of the Rocket Report! The big news in rocketry this week was that NASA still hasn't solved the problem with hydrogen leaks on the Space Launch System. The problem caused months of delays before the first SLS launch in 2022, and the fuel leaks cropped up again Monday during a fueling test on NASA's second SLS rocket. It is a continuing problem, and NASA's sparse SLS launch rate makes every countdown an experiment, as my colleague Eric Berger wrote this week. NASA will conduct another fueling test in the coming weeks after troubleshooting the rocket's leaky fueling line, but the launch of the Artemis II mission is off until March.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

Blue Origin "pauses" New Shepard flights. Blue Origin has "paused" its New Shepard program for the next two years, a move that likely signals a permanent end to the suborbital space tourism initiative, Ars reports. The small rocket and capsule have been flying since April 2015 and have combined to make 38 launches, all but one of which were successful, and 36 landings. In its existence, the New Shepard program flew 98 people to space, however briefly, and launched more than 200 scientific and research payloads into the microgravity environment.

SpaceX has formally acquired another one of Elon Musk's companies, xAi, the space company announced on Monday afternoon.

"SpaceX has acquired xAI to form the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform," the company said. "This marks not just the next chapter, but the next book in SpaceX and xAI's mission: scaling to make a sentient sun to understand the Universe and extend the light of consciousness to the stars!"

The merging of what is arguably Musk's most successful company, SpaceX, with the more speculative xAI venture is a risk. Founded in 2023, xAI's main products are the generative AI chatbot Grok and the social media site X, formerly known as Twitter. The company aims to compete with OpenAI and other artificial intelligence firms. However, Grok has been controversial, including the sexualization of women and children through AI-generated images, as has Musk's management of Twitter.

Ukraine and SpaceX say they recently collaborated to stop strikes by Russian drones using Starlink and will soon block all unregistered use of Starlink terminals in an attempt to stop Russia's military from using the satellite broadband network over Ukraine territory.

Ukrainians will soon be required to register their Starlink terminals to get on a whitelist. After that, "only verified and registered terminals will be allowed to operate in the country. All others will be disconnected," the Ukraine Ministry of Defense said in a press release today.

Ukraine Minister of Defense Mykhailo Fedorov "emphasized that the only technical solution to counter this threat is to introduce a 'whitelist' and authorize all terminals," according to the ministry. "This is a necessary step by the Government to save Ukrainian lives and protect critical energy infrastructure," Fedorov said.

A consequential debate that has been simmering behind closed doors at NASA Headquarters in Washington, DC, must soon come to a head. It concerns the selection of the next spacecraft the agency will fly to Mars, and it could set the tone for the next decade of exploration of the red planet.

What everyone agrees on is that NASA needs a new spacecraft capable of relaying communications from Mars to Earth. This issue has become especially acute with the recent loss of NASA's MAVEN spacecraft. NASA's best communications relay remains the Mars Reconnaissance Orbiter, which has now been there for 20 years.

Congress cared enough about this issue to add $700 million in funding for a "Mars Telecommunications Orbiter" in the supplemental funding for NASA provided by the "One Big Beautiful Bill" passed by the US Congress last year.

SpaceX has made a new set of demands on state governments that would ensure Starlink receives federal grant money even when residents don't purchase Starlink broadband service.

SpaceX said it will provide "all necessary equipment" to receive broadband "at no cost to subscribers requesting service," which will apparently eliminate the up-front hardware fee for Starlink equipment. But SpaceX isn't promising lower-than-usual monthly prices to consumers in those subsidized areas. SpaceX pledged to make broadband available for $80 or less a month, plus taxes and fees, to people with low incomes in the subsidized areas. For comparison, the normal Starlink residential prices advertised on its website range from $50 to $120 a month.

SpaceX's demands would also guarantee that it gets paid by the government even if it doesn't reserve "large portions" of Starlink network capacity for homes in the areas that are supposed to receive government-subsidized Internet service. Moreover, SpaceX would not be responsible for ensuring that Starlink equipment is installed correctly at each customer location.
