CEO Elon Musk says SpaceX has successfully expanded the envelope of orbital-class rocket recovery with its 50th booster landing, meaning that all Falcon boosters will have a better chance of safely returning to Earth from now on.

On March 6th, after a four-day delay, a flight-proven SpaceX Falcon 9 rocket, new second stage, and twice-flown Cargo Dragon spacecraft successfully lifted off on the company’s 20th NASA Commercial Resupply Services mission (CRS-20). Dragon capsule C112 and its expendable trunk section are heading up Earth’s orbital hill to rendezvous with the International Space Station (ISS) tomorrow morning, nominally delivering some two metric tons (~4500 lb) of cargo to the ISS and its crew of astronauts. Once the spacecraft returns to Earth, SpaceX’s Dragon 1 program will effectively be over, wrapping up almost a decade of launches with some 45 metric tons (100,000 lb) of cargo delivered to the ISS.

Back on the ground, SpaceX’s Falcon rocket family still has a long life ahead of it and is likely to support one or several hundred more launches between now and its retirement. Additionally, Elon Musk says that the specific Falcon 9 rocket that launched CRS-20 has now proven that SpaceX rocket boosters can successfully land back on Earth even when ground winds are exceptionally high, hopefully guaranteeing many more booster recoveries to come.

Teslarati photographer Richard Angle was on site to capture the spectacular launch and landing. The exceptionally detailed long-exposure image above includes the entirety of Falcon 9 B1059’s launch and landing, from main engine cut-off (MECO) and boostback burn to the booster’s reentry and landing burns.

Finally, B1059 ignited its engines for the fourth and final time for a landing burn, coming to a rest at Landing Zone 1 (LZ-1) approximately eight minutes after liftoff. (Richard Angle)

According to Musk, this particular landing was unique because it proved Falcon boosters can be successfully recovered – with a bulls-eye landing, no less – even when winds are high around the landing zone (or drone ship). SpaceX intentionally took this risk in part to expand Falcon 9’s safe envelope of operations, which now includes both winds during liftoffs and winds during landings.

While Cargo Dragon 1 may be on its way to the ISS for the last time, SpaceX won a second ‘Phase 2’ CRS contract from NASA that will see the company begin cargo launches to the space station with its Dragon 2 spacecraft – a lightly modified Crew Dragon – as early as Q4 2020, give or take a month. Prior to that mission, known as CRS-21, Crew Dragon is expected to launch at least once and possibly twice, first carrying two NASA astronauts to the ISS on its Demo-2 test flight and SpaceX’s inaugural crewed launch. There’s also a limited chance that SpaceX will flawlessly complete Demo-2 and be able to prepare a second Crew Dragon for its first operational astronaut launch (deemed ‘Crew-1’) before the end of 2020.

For now, SpaceX’s next Dragon launch will also be the company’s first astronaut launch ever. Crew Dragon’s Demo-2 mission is scheduled to lift off no earlier than late-April or May 2020.

xAI’s Grok approved for Pentagon classified systems: report

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations.

Elon Musk’s xAI has signed an agreement with the United States Department of Defense (DoD) to allow Grok to be used in classified military systems.

Previously, Anthropic’s Claude had been the only AI system approved for the most sensitive military work, but a dispute over usage safeguards has reportedly prompted the Pentagon to broaden its options, as noted in a report from Axios.

Under the agreement, Grok can be deployed in systems handling classified intelligence analysis, weapons development, and battlefield operations. 

The publication reported that xAI agreed to the Pentagon’s requirement that its technology be usable for “all lawful purposes,” a standard Anthropic has reportedly resisted due to alleged ethical restrictions tied to mass surveillance and autonomous weapons use.

Defense Secretary Pete Hegseth is scheduled to meet with Anthropic CEO Dario Amodei in what sources expect to be a tense meeting, with the publication hinting that the Pentagon could designate Anthropic a “supply chain risk” if the company does not lift its safeguards. 

Axios stated that replacing Claude fully might be technically challenging even if xAI or other alternative AI systems take its place. That being said, other AI systems are already in use by the DoD. 

Grok already operates in the Pentagon’s unclassified systems alongside Google’s Gemini and OpenAI’s ChatGPT. Google is reportedly close to an agreement that will result in Gemini being used for classified use, while OpenAI’s progress toward classified deployment is described as slower but still feasible. 

The publication noted that the Pentagon continues talks with several AI companies as it prepares for potential changes in classified AI sourcing.

Elon Musk denies Starlink’s price cuts are due to Amazon Kuiper

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X.

Elon Musk has pushed back on claims that Starlink’s recent price reductions are tied to Amazon’s Kuiper project.

In a post on X, Musk responded directly to a report suggesting that Starlink was cutting prices and offering free hardware to partners ahead of a planned IPO and increased competition from Kuiper.

“This has nothing to do with Kuiper, we’re just trying to make Starlink more affordable to a broader audience,” Musk wrote in a post on X. “The lower the cost, the more Starlink can be used by people who don’t have much money, especially in the developing world.”

The speculation originated from a post summarizing a report from The Information, which ran with the headline “SpaceX’s Starlink Makes Land Grab as Amazon Threat Looms.” The report stated that SpaceX is aggressively cutting prices and giving free hardware to distribution partners, which was interpreted as a reaction to Amazon’s Kuiper’s upcoming rollout and possible IPO.

In a way, Musk’s comments could be quite accurate considering Starlink’s current scale. The constellation currently has more than 9,700 satellites in operation today, making it by far the largest satellite broadband network in operation. It has also managed to grow its user base to 10 million active customers across more than 150 countries worldwide. 

Amazon’s Kuiper, by comparison, has launched approximately 211 satellites to date, as per data from SatelliteMap.Space, some of which were launched by SpaceX’s Falcon 9 rocket. Starlink surpassed that number in early January 2020, during the early buildout of its first-generation network.

Lower pricing also aligns with Starlink’s broader expansion strategy. SpaceX continues to deploy satellites at a rapid pace using Falcon 9, and future launches aboard Starship are expected to significantly accelerate the constellation’s growth. A larger network improves capacity and global coverage, which can support a broader customer base.

In that context, price reductions can be viewed as a way to match expanding supply with growing demand. Musk’s companies have historically used aggressive pricing strategies to drive adoption at scale, particularly when vertical integration allows costs to decline over time.

Tesla Giga Berlin is sending a strong message of solidarity amid its ongoing legal dispute with German union IG Metall.

In a post on social media platform X, Giga Berlin plant manager André Thierig shared an image of the facility’s lobby covered with a large banner that reads: “Progress. Innovation. Success.” He added that the slogan reflects what the facility has stood for since Day One.

“Our lobby at Giga Berlin covered in a huge banner these days. Progress. Innovation. Success – this is what we stand for since we started production in 2022 and how we will go into our future!” Thierig wrote in his post on X. 

The display comes as tensions between Tesla and IG Metall continue to escalate.

The dispute began after Tesla accused a union representative of secretly recording a works council meeting at Giga Berlin. Tesla stated that it filed a criminal complaint after the alleged incident. Police later confirmed they had seized a computer belonging to an IG Metall member as part of their investigation.

“What has happened today at Giga Berlin is truly beyond words! An external union representative from IG Metall attended a works council meeting. For unknown reasons he recorded the internal meeting and was caught in action! We obviously called police and filed a criminal complaint!” Thierig wrote on X at the time

IG Metall denied the accusation and characterized Tesla’s move as an election tactic ahead of upcoming works council elections. The union subsequently filed a defamation complaint against Thierig. Authorities later confirmed that an investigation had been opened in connection with the matter.

Giga Berlin began production in 2022 and has since become one of Tesla’s key European manufacturing hubs, producing the Model Y, the company’s best-selling vehicle. The facility has expanded capacity over the past years despite environmental protests, labor disputes, and regulatory scrutiny.
