SpaceX has completed its second successful launch of 2019, sending the first commercial Moon lander on the first leg of its journey to the lunar surface with a sooty Falcon 9 Block 5 rocket.

Built by Israeli aerospace company IAI for customer SpaceIL, the Moon lander – named Beresheet, Hebrew for “in the beginning” – is just one of three payloads present on this launch, gently perched with Air Force satellite S5 atop Indonesian communications satellite PSN-6. According to SpaceX, Falcon 9 B1048’s third successful launch and landing faced the Block 5 booster with “some of the most challenging reentry conditions to date”.

After separating from Falcon 9’s upper stage and payload at an altitude of 68 km (43 mi) and a velocity of nearly 2.4 km/s (1.5 mi/s, Mach 7+), B1048 continued on in the near-vacuum of suborbital space, likely peaking at 80-100 km before heading back down into the thicker parts of Earth’s atmosphere. Despite what one SpaceX engineer described as “the most challenging reentry conditions to date”, B1048 appeared to perform perfectly over the course of its third launch and landing.

According to SpaceX CEO Elon Musk, the booster could fly again as early as April in support of Crew Dragon’s in-flight abort mission, although his implication that that test will occur in April directly contradicts a recent NASA schedule update that pegged the test no earlier than (NET) June 2019.

Shortly before the main PSN-6 satellite was deployed from Falcon 9’s upper stage, one of SpaceX’s launch network operators verbally confirmed that SpaceIL’s Beresheet lander had established communications with the ground and successfully deployed its landing legs in orbit, one tangible step closer to the first attempted commercial Moon landing. Beresheet and PSN-6 will now take opposite paths forward, with the lunar lander raising its orbit quite literally to the Moon while PSN-6 drops its high end down and circularizes at approximately 35,800 km (22,250 mi) above Earth.

Combined with Musk’s apparent belief that B1048 – having just experienced what he described as the “highest reentry heating to date” – could be ready to launch again as few as 40-70 days from now, this successful launch and landing of a flight-proven Falcon 9 booster (the second time a SpaceX rocket as flown for the third time) suggests that the Block 5 upgrade continues to operate nominally. Designed to radically improve the ease and speed of Falcon 9 booster reuse, Block 5 debuted in May 2018 and has now launched 12 times, with half of those missions flying on flight-proven boosters. The proportion of flight-proven to new booster launches is likely to continue to grow in 2019, ultimately reaching a point where new boosters are limited to inaugural hardware debuts or specific contractual requests from conservative US government customers.

Up next for SpaceX is the imminent orbital launch debut of Crew Dragon, set to occur no earlier than March 2nd. While a slip of several days or more is not out of the question, the lack of date movement less than ten days out from the target launch date suggests that this particular date is far more confident than the several that preceded it. Regardless, we’ll find out tomorrow just how confident NASA and SpaceX are in DM-1’s March 2nd launch plan.

SpaceX Starship Flight 13 faces wrath of the Texas skies

SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.

Published

SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”

This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.

Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.

Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.

Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.

If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.

Google’s massive stake in SpaceX will shock you

In a striking revelation that underscores the lucrative crossover between Big Tech and space exploration, Alphabet Inc., Google’s parent company, disclosed a massive $94.1 billion equity stake in SpaceX following the rocket company’s blockbuster initial public offering earlier this year.

The disclosure came in Alphabet’s quarterly filing, marking the first time the long-held private investment has been publicly valued at market prices. Google was an early backer, investing alongside Fidelity in 2015 with roughly $500-900 million at a time when SpaceX was valued around $12 billion.

That bet has delivered extraordinary returns, roughly a hundredfold, transforming a strategic play on satellite internet and launch capabilities into one of Alphabet’s largest assets.

Of the total holding, approximately $80 billion remains subject to short-term post-IPO lockup restrictions, preventing near-term sales. An additional $14.1 billion faces longer-term restrictions, extending into the third quarter of 2027. This structure limits immediate liquidity but protects against market volatility as SpaceX transitions into public trading.

The SpaceX position contributed significantly to gains in Alphabet’s broader investment portfolio, which also includes a major stake in AI leader Anthropic. Combined, these holdings helped drive nearly $100 billion in investment gains during the second quarter, providing a substantial boost to net income amid ongoing AI spending pressures.

Elon Musk sends first warning to SpaceX short sellers

Analysts view the disclosure as validation of Alphabet’s venture strategy beyond its core search and cloud businesses. The investment aligns with deeper ties, including reported multi-billion-dollar deals for AI computing capacity on SpaceX infrastructure. As SpaceX advances Starship flights, Starlink expansion, and ambitious Mars goals under Elon Musk, Google’s stake positions it to benefit from the commercialization of space.

For Alphabet, the windfall highlights how patient, forward-looking bets in transformative sectors can yield outsized rewards. While lockups temper short-term impact, the holding cements SpaceX as a cornerstone of Alphabet’s diversified portfolio in an era where aerospace, AI, and connectivity increasingly intersect. Investors will watch closely as restrictions lift and SpaceX’s public performance unfolds.

Elon Musk handed Grok something no other AI company can get their hands on

Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.

Artistic concept rendering of SpaceX data being incorporated into a Grok AI model

Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.

The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.

Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.

Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.

Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
