SpaceX set to launch its first previously-flown Block 5 rocket tonight

Published

on

At the same time as SpaceX is readying its first Falcon 9 Block 5 booster reuse, the company’s second flight-proven Block 5 launch is already fast approaching and could be a strong contender to beat the company’s record of 72 days between launches of the same rocket.

A critical milestone for Falcon 9 Block 5

Formerly known as Telkom 4, SpaceX’s 1:18 AM EDT August 7th launch of the Merah Putih (Red and White in Indonesian) communications satellite will place the 5800 kg (12,800 lb) craft into a high-energy geostationary transfer orbit and will become the second heaviest GTO launch completed by SpaceX while still recovering the Falcon 9 booster. More importantly, however, Telkom 4 will also mark a critical milestone for Falcon 9 as the first reuse of a Block 5 booster.

Designed to be many times more reusable and reliable than the already impressive Falcon 9 Full Thrust iterations preceding it, pathfinder booster B1046 could be capable of flying anywhere from 5, 10, or even 100 launches over the course of its flightworthy lifespan. It very well may require some considerable refinements to approach the true goal of orbital Falcon 9 launches with zero refurbishments between flights. CEO Elon Musk discussed those aspirations just before Block 5’s launch debut on May 11:

“We need to basically take the rocket from its landing pad, rotate it horizontal, stow the legs. Take it to the launch pad, attach an upper stage, attach a fairing with a payload. Then transport it out the launch pad, rotate it vertically, load propellant, and fly. And in principle, that is literally all that’s necessary.” – Elon Musk

This is understandably SpaceX’s goal, and it’s unlikely to happen just a few months after Block 5’s debut. Nevertheless, SpaceX appears to be already pushing the envelope of what they’ve previously accomplished with reusable Falcon 9s.

Breaking records four months after launch debut

While B1046 is tracking towards a booster turnaround of roughly 92 days, compared with the current Block 4 booster record of 72 days, it’s worth noting that more than a majority of that time was likely spent in a state of unique analysis for the inaugural Block 5 rocket, involving extensive disassembly. As stated by Musk, “we need to take [B1046] apart to confirm that it does not need to be taken apart.” He also expected that teardown analysis to be “very rigorous”, indicating that B1046 probably deserves the crown for booster turnaround so long as one only accounts for time spent in transport and undergoing refurbishment.

Still, winning by a technicality is never any fun. On that note, SpaceX appears to be tracking towards a true record-breaking rocket reuse, potentially as few as 40 days between launches. Not one to let its other launch facilities be left out, this record-breaking turnaround attempt will occur on the West Coast with Falcon 9 B1048, the recovery of which has been extensively documented by Teslarati photographer Pauline Acalin over the last two weeks. NASASpaceflight.com confirmed that SpaceX intends to reuse B1048 for this mission for the NET mid-September launch and the record ~50 days between flights could help explain an unusually extensive and lengthy analysis of the rocket after it was lifted off drone ship Just Read The Instructions and placed on its dockside recovery stand.

After 10 days of recovery operations and analysis, B1048 was transported to SpaceX’s Hawthorne factory on August 6th, where it will presumably undergo refurbishment in preparation for its next launch. If B1046 and B1048 are representative samples of SpaceX’s growing rocket fleet, their stunningly quick turnarounds (especially for a largely new rocket that debuted less than 3-4 months prior) are likely a sign of things to come as SpaceX gets a handle on the real-world capabilities of its robust Block 5 upgrade.

It’s entirely possible that every Block 5 reuse to come can and will break the previous launch turnaround record, at least up to the point that SpaceX demonstrates a true 24-hour turnaround sometime next year. Stay tuned…

ARK’s SpaceX IPO Guide makes a compelling case on why $1.75T may not be the ceiling

ARK Invest breaks down six reasons SpaceX’s $1.75 trillion IPO valuation may be justified.

Published

on

By

ARK Invest, which holds SpaceX as its largest Venture Fund position at 17% of net assets, has published a detailed investor guide to why a SpaceX IPO may be grounded in a $1.75 trillion target valuation.

The financial case starts with Starlink, SpaceX’s satellite internet constellation, which has surpassed 10 million active subscribers globally as of early 2026, with 2026 revenue projected to exceed $20 billion. ARK’s research puts the total satellite connectivity market opportunity at roughly $160 billion annually at scale, and Starlink is adding customers faster than any telecom network in history. That growth alone would justify a substantial valuation.

Additionally,  ARK notes that SpaceX has reduced the cost per kilogram to orbit from roughly $15,600 in 2008 to under $1,000 today through reusable Falcon 9 hardware. A fully operational Starship targeting sub-$100 per kilogram would represent a significant cost decline and open markets that do not currently exist. SpaceX executed a staggering 165 missions in 2025 and now accounts for approximately 85% of all global orbital launches. That infrastructure position took decades to build and would be nearly impossible to replicate at comparable cost.

The February 2026 merger with xAI added a layer to the valuation that straightforward financial models struggle to capture. ARK argues that at sub-$100 launch costs, orbital data centers could deliver compute roughly 25% cheaper than ground-based alternatives, without power grid delays, permitting friction, or land constraints. Musk has stated a goal of deploying 100 gigawatts of AI computing capacity per year from orbit.

The $1.75 trillion figure itself is not a conventional earnings multiple. At roughly 95x trailing revenue, it prices in Starlink’s adoption curve, Starship’s cost trajectory, and the orbital compute thesis together. The public S-1 prospectus, due at least 15 days before the June roadshow, will give investors their first complete look at the financials to test those assumptions. ARK’s position is that the track record earns the benefit of the doubt. Fully reusable rockets were considered unrealistic for years. Starlink was considered financially unviable. Both happened on timelines that surprised skeptics.

Ford CEO Farley says Tesla is not who to look at for EV expertise

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Ford CEO Jim Farley said in a recent podcast interview that Tesla is not who Americans should look at to beat Chinese carmakers.

The comments have sparked quite a bit of outrage from Tesla fans on X, the social media platform owned by Elon Musk.

Farley said that Chinese automakers are better examples of how to beat competitors. He said (via the Rapid Response Podcast):

“If you’re an American and you want us to beat the Chinese in the car business, you’re all going to want to pay attention, not necessarily to Tesla. Nothing against Tesla—they’ve been doing great—but they really don’t have an updated vehicle. The best in the business for us, cost-wise and competition-wise, supply chain, manufacturing expertise, and the I.P. in the vehicle, was really BYD. In this next cycle of EV customers in the U.S., they want pickups and utilities and all these different body styles. But they want them at $30,000, not $50,000. Like the first inning, they want them affordably.”

Despite Farley’s synopsis, it is worth mentioning that Tesla had the best-selling passenger vehicle in the world last year, and in China in March, as the Model Y continued its global dominance over other vehicles.

Musk responded to Farley’s comments by stating:

“This is before Supervised FSD is approved in China. Limiting factor is production output in Shanghai.”

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Instead, Ford is “doubling down on its affordable” EVs and said it would pivot from its previous plans.

Reaction from Tesla fans was pretty much how you would expect. Many said they have lost a lot of respect for Farley after his comments; others believe he is the last CEO anyone should be taking advice on EVs from.

Nevertheless, Farley’s plans are bold and brash; many consider Tesla the most ideal company to replicate EV efforts from. It will be interesting to see if Ford can rebound from this big adjustment, and hopefully, Farley’s plans to replicate efforts from BYD work out the way he hopes.

SpaceX wins its first MARS contract but it comes with a catch

NASA awarded SpaceX a $175 million Mars rover contract while the White House proposes cutting the mission.

Published

By

NASA just signed a $175.7 million contract with SpaceX to launch a Mars rover that the White House is simultaneously trying to defund. The contract, awarded on April 16, 2026, tasks SpaceX’s Falcon Heavy with launching the European Space Agency’s (ESA) Rosalind Franklin rover from Kennedy Space Center in Florida, no earlier than late 2028. It would mark the first time SpaceX has ever sent a payload to Mars.

Under NASA’s Rosalind Franklin Support and Augmentation project, known as ROSA, the agency is providing braking engines for the rover’s descent stage, radioisotope heater units that use decaying plutonium to keep the rover warm on the Martian surface, additional electronics, and a mass spectrometer instrument, as noted by SpaceNews.

Those nuclear heating units are the reason an American rocket was required at all. U.S. export controls on radioisotope technology mean any payload carrying them must launch on a domestic vehicle, which narrowed the field to SpaceX and United Launch Alliance. Falcon Heavy’s pricing made it the practical choice.

Falcon Heavy debuted in February 2018 and has 11 launches to its record. The rocket has not flown since October 2024, when it sent NASA’s Europa Clipper toward Jupiter. The three-core design, built from modified Falcon 9 first stages, gives it the lift capacity needed for deep space planetary missions that a single Falcon 9 cannot reach.

The Rosalind Franklin rover has been sitting in storage in Europe for years. It was originally due to launch in 2022 as a joint mission with Russia, but Russia’s invasion of Ukraine ended that partnership, leaving the rover built but stranded without a launch vehicle or landing hardware. NASA stepped back in through a 2024 agreement with ESA to rescue the mission. The rover is designed to drill up to two meters below the Martian surface in search of evidence of past life, a science objective no previous mission has attempted at that depth.

The contradiction at the center of this story is hard to ignore. The White House’s fiscal year 2027 budget proposal included no funding for ROSA and did not mention the mission at all in the detailed congressional justification document released April 3.

Musk has long argued that reaching Mars is not optional. “We don’t want to be one of those single planet species, we want to be a multi-planet species.” Whether this particular mission survives Washington’s budget fight, the Falcon Heavy contract means SpaceX is now formally on record as the rocket that could get humanity’s next Mars science mission off the ground.

The timing of this contract carries extra weight given that SpaceX filed confidentially with the SEC in early April and is targeting an IPO roadshow in the week of June 8. It would be the largest public offering in history.
