SpaceX nails first rocket landing by sea in half a year, sends exoplanet probe beyond the Moon
SpaceX has successfully completed the first drone ship recovery of a Falcon 9 booster in nearly six months, bringing to an end a what will likely be the final drought of by-sea rocket landings in the company’s history.
B1045’s landing was a particularly stunning example of just how far SpaceX has come. By all appearances, the recovery was easily the smoothest yet achieved by the company, with nary a hint of reentry heating visible in the near-flawless live coverage from a camera aboard the booster. Perhaps of even more interest, the landing itself appeared to be exceptionally luxurious, with the booster gently floating down to its final resting perch aboard the drone ship Of Course I Still Love You.
This return-to-landing, so to speak, is SpaceX’s 24th successful Falcon booster recovery in just over three years of true recovery efforts. The last several months have featured an unfamiliar number of intentionally expendable launches, in which SpaceX chose to preclude any attempt at recovery, instead typically gently landing the boosters in the ocean to gather additional flight-test data and to explore the envelope of Falcon 9’s recovery capabilities. In all cases but one (Hispasat 30W-6), these intentionally expended boosters were older, flight-proven versions of the rocket, versions that hadn’t been designed to economically fly more than once or twice.
B1045, however, has just one flight under its belt, and is already pegged for a second launch with CRS-15, giving the booster as few as 50 days to be refurbished and prepped for its second pre-launch static fire (likely the first week of June). This would be an exceptionally fitting case of foreshadowing for SpaceX’s upcoming Block 5 iteration of Falcon 9. If a Block 4 booster can be launched, landed, and refurbished in well under two months, one can only imagine what a Falcon 9 explicitly upgraded for ease of reuse will be capable of.

Over the past six months, SpaceX has aggressively expanded their program of orbital rocket reuse, leaping from just three operational reflights of Falcon 9 boosters in the process’ first half-year (Mar-Oct ’17) to seven operational reflights between the following months of December and April. Today, April 18, the successful launch of NASA’s Transiting Exoplanet Survey Satellite (TESS) marks the final launch of a new Block 4 Falcon 9 booster (B1045) – although we can expect as many as three additional reflights of recovery Block 4 boosters in 2018, all new Falcon 9 boosters from here on out will be Block 5s, a final upgrade to the rocket designed to significantly optimize reliability and reusability. The first Falcon 9 Block 5 is expected to debut sometime in May, currently No Earlier Than (NET) May 4.
Impressively, despite the fairly extensive modifications and upgrades – both for reliability and reusability – included in Falcon 9 Block 5, SpaceX’s Hans Koenigsmann stated that the lengthy test campaign in Texas went well and was in fact “faster than we’ve ever had on new Block upgrades [of Falcon 9].” SpaceX themselves have not yet given a specific date for the debut of Block 5, but Hans did partially confirm recent reports that it is now targeting a debut in “early May” with the launch of Bangabandhu-1. Put simply, so long as things go more or less according to plan, 2018 will in every conceivable way usher in the real future of orbital-class reusable rockets – perhaps enabling the sort of responsive, cheap, and reliable access to space long ago promised by CEO Elon Musk.

TESS will dramatically increase the number of known exoplanets. It will more than double the number found by Kepler. #NASA #TESS #SpaceX #Falcon9

Despite its diminutive size and 350 kg mass, TESS is expected to dramatically expand the number of detected exoplanets in the universe, and is tasked with surveying the remaining 95% of the sky left unscanned after Kepler’s famous mission. Ultimately, conservative estimates from astronomers expect TESS to add thousands of new exoplanets to humanity’s current catalog, with perhaps as many as 10% of those discovered likely to be Earth-sized, and thus potential candidates for the first habitable planets to be observed beyond the cozy bounds of our own Solar System.
To give a sense of just how far electronics and satellite technology have improved in the decade since the Kepler observatory was launched (2009), that 1050kg spacecraft was designed to stare specifically at one small segment of the sky (0.25%), scanning it ceaselessly for exoplanets. Despite complex technical difficulties, Kepler managed to discover nearly 1100 confirmed exoplanets, with more than 3000 additional candidates waiting to be confirmed by other spacecraft or telescopes.

On the other hand, the 350kg TESS, has been designed to sca the entire sky and may well double, triple, or quadruple the number of known exoplanets in the universe. Falcon 9 may undoubtedly be a bit like using a dump truck when a shovel would do, but the tiny size of the payload can be thanked for the exceptionally gentle booster recovery and the equally (relatively) easy refurbishment soon to follow.

Tesla starts preparing for Optimus in its smartphone app
Tesla is starting to prepare for the launch of the Optimus robot in its smartphone app, new coding strings show. Elon Musk has referred to Optimus as what will be the greatest-selling product of any kind of all time, and now, Tesla is getting ready for its launch.
Tesla’s smartphone app had several first-time mentions of the Optimus program, according to Tesla App Updates, who intially reported on the appearance. Here’s what they found:
A Dedicated “Robot” Phone Key Authentication
Tesla is working on a Bluetooth Low Energy, or BLE, authentication that is specifically for robots. This does not only apply to Optimus, though, as Robotaxi, which is Tesla’s autonomous ride-hailing platform, might also identify vehicles within the fleet as robots as well.
Tesla shows rapid teardown of Model S and X lines, paving the way for Optimus at Fremont
Essentially, pairing your phone as a key to anything Tesla identifies as a robot to a “whitelist” of authorized devices. Optimus, Robotaxi, or other products that fall into this category will only respond if the device trying to communicate with it is authorized.
This is a great security feature that will eliminate at least face-value and low-level threats.
Home Data Collection and System Alerts
This appears to be somewhat of a neural network for Optimus within your house. There will be a dedicated screen that asks for consent to collect both video and spatial data while Optimus performs in-home tasks. Everything from vacuuming, washing dishes, dusting, and other activities will be tracked.
There will also be a comprehensive alert system that will track everything from low battery to mechanical issues.
Other Changes
Most of the changes tracked in this particular app update are related to Tesla’s 2026 Summer Update, and include things such as image assets for new features, a preview of the new custom wraps feature, and other unique features.

Investor's Corner
Tesla Q2 Earnings: Here’s what to expect
Tesla (NASDAQ: TSLA) will report its earnings for the second quarter of 2026 this evening after market close, and investors and analysts are waiting anxiously to see what the company will report for the second three-month span of the year.
Analysts have already put out their expectations from a financial standpoint for the company’s second quarter, but what’s unknown is what Tesla plans to discuss during the call.
Financial Expectations
Wall Street consensus expectations put Tesla’s Earnings Per Share (EPS) at $0.53, while revenues are expected to come in around $26.4 billion.
This would compare to an EPS of $0.39 and $22.19 billion compared to Tesla’s Q2 2025. Last quarter, EPS came in at $0.41 on $22.387 billion of revenue. Additionally in Q1, Tesla beat analyst expectations, but shares dropped over 3 percent the following trading day.
What We Expect
In terms of discussions, Tesla earnings are pretty sporadic and depend on a handful of things, including current events, investor questions, and more.
Tesla uses a platform called Say to field questions from investors and analysts. These questions are what will be used during the call. Here are the top 5 from the Retail side and top 3 from the Institutional side:
Retail:
“Tesla has missed short-term guidance on robotaxi 3 earnings reports in a row, from 50% coverage of USA by end of 2025 to most recently 7 new cities in 1H26. What is keeping Tesla back from accomplishing these short term goals that they’ve set for themselves?”
“What are the main constraints to expanding robotaxi operations faster, and how do you see that lining up with Cybercab production?”
“What’s the current status of Optimus Gen 3 production ramp, initial deployment in factories, and external sales timeline/volume for 2027? What tasks can we expect the Optimus to perform by end of 2027?”
“To reward long-term Tesla retail shareholders for their loyalty, can you commit to achieving at least half of the goals outlined in your 2025 compensation plan before considering any offers to acquire or merge Tesla?”
“Why has growth of robotaxi vehicles stalled? When will we see cybercab start customer rides?”
Institutional
“Previously, you’ve said Tesla would lead the R&D while SpaceX would lead production for Terafab. Can you provide an update on how that division of responsibilities is evolving, and any additional clarity on the expected capital contributions from Tesla and SpaceX?”
“For autonomous driving, Tesla’s fleet created a huge data advantage by collecting billions of real-world miles. That advantage doesn’t yet exist for Optimus. How should we think about data availability and its impact on Optimus development?”
“Why is it necessary to limit robotaxi operations within specific zones within cities to start? Will every city have to be rolled out this way?”
Tesla will report earnings for Q2 this evening with the Shareholder Deck at 4 p.m. ET, with the call starting around 5:30 p.m. ET.

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.
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.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
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.
