SpaceX nails first rocket landing by sea in half a year, sends exoplanet probe beyond the Moon

Published

on

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.

Science galore

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 has expanded its Semi pilot program to a new region, as it has made it to Texas to be tested by logistics from Mone Transport. With the Semi entering production this year, Tesla is getting even more valuable data regarding the vehicle and its efficiency, which will help companies cut expenditures.

Mone Transport operates in Texas and on the Southern border, and it specializes in cross-border U.S.-Mexico freight operations. After completing some rigorous testing, Mone shared public results, which stand out when compared to efficiency metrics offered by diesel vehicles.

“Mone Transport recently had the opportunity to put the Tesla Semi to the test, and we’re thrilled with the results! Over 4,700 miles of operations at 1.64 kWh/mile in our Texas operation. We’re committed to providing zero-emission transportation to our customers!” the company said in a post on X.

Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.

Comparable Class 8 diesel semis, typically achieving 6-7 miles per gallon, consume roughly 5.5 kWh per mile in energy-equivalent terms, meaning the Semi uses three to four times less energy while also producing zero tailpipe emissions.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries

The performance of the Tesla Semi in Mone Transport’s testing aligns with data from other participants in the pilot program. ArcBest’s ABF Freight Division logged 4,494 miles over three weeks in 2025, averaging 1.55 kWh per mile across varied routes, including a grueling 7,200-foot Donner Pass climb. The truck “generally matched the performance of its diesel counterparts,” the carrier said.

PepsiCo, which operates the largest known Semi fleet, recorded 1.7 kWh per mile in North American Council for Freight Efficiency testing. Additional pilots showed similar gains: DHL hit 1.72 kWh per mile, and Saia achieved 1.73 kWh per mile.

These metrics underscore the Semi’s ability to slash operating costs through superior efficiency, lower maintenance, and zero-emission operation. As charging infrastructure scales and production ramps toward 2026 targets, participants like Mone Transport are proving electric semis can seamlessly integrate into freight networks, accelerating the industry’s shift to sustainable, high-performance trucking.

Tesla continues to prep for a more widespread presence of the Semi in the coming months as it recently launched the first public Semi Megacharger site in Los Angeles. It is working on building out infrastructure for regional runs on the West Coast initially, with plans to expand this to the other end of the country in the coming years.

Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history. 

As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.

According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.

Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.

One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.

Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.

Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.

If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.

Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.

Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.

According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.

According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.

The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.

The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.

Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.

The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.

The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026. 

As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.

CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.

The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.
