SpaceX spotted hot-fire testing Falcon 9 Block 5 ahead of its first reflight on August 7

Published

on

Less than three months after SpaceX debuted its upgraded Falcon 9 Block 5 rocket, the company is set for an unexpectedly sudden inaugural reuse of the first highly reliable and reusable rocket to roll off of the Hawthorne, CA assembly line. Falcon 9 booster 1046 (B1046) is now targeting 1:18 AM EDT, August 7 for its second launch.

Confirmed by visual observation of a sooty Block 5 booster vertical on Cape Canaveral’s Pad 40, this reuse will be just two weeks away from beating SpaceX’s booster turnaround record of 72 days.

On the ground to visually confirm plans for the historic reuse, Teslarati photographer Tom Cross also managed to capture an intriguing propellant loading and abort test, where SpaceX appeared to intentionally abort a ‘launch’ attempt after rapidly loading a full complement of liquid oxygen (LOX) and rocket-grade kerosene (RP-1).

While not 100% clear why this testing was done today, an extensive understanding of Falcon 9 Block 5’s behavior during propellant late-load and launch abort scenarios are both critical for the reliable operation of the upgraded rockets and invaluable for the first Crew Dragon launches later this year and early next, the latter with astronauts on board. With humans atop the rocket, a deep understanding of the vehicle’s behavior during a wide range of off-nominal scenarios is more critical than ever, be it required by NASA or simply a side effect of due diligence on behalf of SpaceX.

A new era of reusable rockets

Regardless, the main focus of this mission is to launch a payload for Indonesian operator PT Telkom Indonesia, in this case a ~5800 kg (12800 lb) geostationary communications satellite known as Merah Putih (formerly Telkom 4). On the SpaceX side of things, this mission is absolutely critical for the company’s future – it will mark the (hopefully) successful inaugural reuse of a Falcon 9 Block 5 booster, the first of many dozens or even hundreds to come over the next several years if SpaceX’s can make good on its aspirations.

While not immensely impressive in the sense that B1046’s refurbishment took ~85 days to Block 4’s record 72-day turnaround, that cursory conclusion is far from accurate. The record turnaround with Block 4 booster B1045 was essentially the culmination of more than a year of experience with nearly a dozen Block 3 and Block 4 Falcon 9 reuses. While that experience definitely transferred in part to SpaceX’s first attempt at reusing Falcon 9 Block 5 (and especially so with the actual design of its reusability-focused upgrades), it’s worth noting that the first reuses of Falcon 9s averaged booster turnaround times of 180-250 days, nearly double or triple the time between Block 5’s first-ever launch and that same booster’s first reflight.

Even still, B1046’s debut launch, landing, and refurbishment were wholly unique considering that SpaceX – according to Elon Musk – conducted an extensive “teardown” analysis of the pathfinder rocket after it was transported from the drone ship back to one of the company’s Cape Canaveral refurbishment facilities. It’s very likely the case that that teardown was one of the most extensive SpaceX has done with a recovered rocket, couched on the fact that the company’s future is wholly balanced on Falcon 9 Block 5’s success and ease/efficiency of reusability.

That critical teardown process likely took anywhere from 30-60 days, if not simply as long as needed to do it right, after which the rocket was fully reassembled and transported to SpaceX’s Launch Complex 40 (LC-40). Roughly eight days after it arrived at LC-40, B1046 rolled out to the pad’s launch mount, went vertical, and completed a series of tests (including static fire) on Thursday (8/2) afternoon. The static fire was confirmed by a few observers, while Tom Cross captured the first unequivocal proof that the rocket is sooty (and thus B1046).

This moment may seem small on the scale of SpaceX’s many towering achievements, but it will very likely become a fundamental keystone in the future history of affordable access to space.

Tesla says it denied Musk CEO replacement report before it was published

Tesla says it responded to the WSJ’s request for comment, denying that it was in search of a new CEO to replace Elon Musk.

Tesla said that it denied seeking a replacement for CEO Elon Musk before a report was published claiming the company was considering a new frontman.

Last night, The Wall Street Journal reported that Tesla’s Board of Directors was looking for Musk’s replacement after he had devoted too much time to his role within the government. The publication revised its headline to the report no fewer than five times, initially stating the company was still seeking a replacement.

By the time the headline revisions were complete, it had outlined that Tesla had looked for a replacement a month ago, but had stopped its search following Musk’s commitment to Tesla during the company’s earnings call last month.

Shortly after the report surfaced, Board of Directors chairwoman Robyn Denholm officially issued a statement on behalf of Tesla:

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead.  – Robyn Denholm.”

Interestingly, Denholm’s statement indicates it had responded to a request for comment from the Wall Street Journal before the report was published. This is especially interesting because Tesla does not typically respond to media outreach, as it dissolved its media department several years ago.

Tesla typically makes its statements publicly on X.

Musk also responded to the report, indicating that the WSJ had committed an “extremely bad breach of ethics” by publishing a “deliberately false article” that did not include Tesla’s “unequivocal denial beforehand.”

Industry leaders such as Elon Musk have always maintained that autonomous robotaxis will make roads safer. A recent blog post from Waymo about the safety of its self-driving cars suggests that Musk’s sentiments are on point.

Way More Safety

Waymo Driver is already reducing severe crashes and enhancing the safety of vulnerable road users. As per a new research paper set for publication in the Traffic Injury Prevention Journal, Waymo Driver had outperformed human drivers in safety, particularly for vulnerable road users (VRUs).

Over 56.7 million miles, compared to human drivers, Waymo Driver achieved a 92% reduction in pedestrian injury crashes. It also saw 82% fewer crashes with injuries with cyclists and 82% fewer crashes with injuries with motorcyclists. Waymo Driver also slashed injury-involving intersection crashes by 96%, which are a leading cause of severe road harm for human drivers. Waymo Driver saw 85% fewer crashes with suspected serious or worse injuries as well.

What They Are Saying

Mauricio Peña, Waymo’s Chief Safety Officer, was optimistic about Waymo Driver’s results so far. “It’s exciting to see the real positive impact that Waymo is making on the streets of America as we continue to expand. This research reinforces the growing evidence that the Waymo Driver is playing a crucial role in reducing serious crashes and protecting all road users,” the Chief Safety Officer noted.

Jonathan Adkins, Chief Executive Officer at Governors Highway Safety Association, also noted that Waymo’s results are very encouraging. “It’s encouraging to see real-world data showing Waymo outperforming human drivers when it comes to safety. Fewer crashes and fewer injuries — especially for people walking and biking — is exactly the kind of progress we want to see from autonomous vehicles,” Adkins stated.

Tesla hints at June 1 launch of Robotaxi platform in Austin

Tesla has hinted at a potential launch date for the Robotaxi service in Austin, Texas.

Tesla just dropped its biggest hint yet about the potential launch date of its Robotaxi ride-hailing platform in Austin, Texas, shedding more light on when to expect it to take off.

In preparation for the ride-hailing service to launch, Tesla has been in talks with the City of Austin for months. It has also spent recent months bolstering its Full Self-Driving suite, aiming for it to handle initially supervised rides with the use of teleoperators to keep things safe and dependable, at least early on.

The company has also said that it expects the Robotaxi service, which will drive passengers in Tesla Model Y vehicles to start, to launch in Austin in June. However, Tesla has not given an exact date.

Now, Tesla is hinting that Robotaxi could launch on June 1, based on a very vague X post it published on May 1:

Of course, this is extremely speculative. However, it’s the first time Tesla has made any suggestions about a potential launch date, so it’s worth taking it seriously.

While the automaker has often missed timelines in the past, most notably the launch of a “feature-complete” Full Self-Driving platform, this is the first time we’ve seen Tesla be so adamant and truly reiterate a target date.

Tesla has not shied away from this June date for the Robotaxi launch yet, something that is worth noting as we move closer to June. All signs point toward Tesla being able to come through on this timeline, and it could be one of its biggest accomplishments yet on the grand scheme of things. The Robotaxi rollout will be controlled and small to start, the company noted on its most recent Earnings Call.

CEO Elon Musk said:

“The team and I are laser-focused on bringing robotaxi to Austin in June. Unsupervised autonomy will first be solved for the Model Y in Austin.”

At first, it also seems as if the first Robotaxi rides will be available to a select group, as Musk said the ability to order one will not be available to the general public until later in the month. He also said the initial fleet will be between 10 and 20 vehicles:

“Yeah. We’re still debating the exact number to start off on day one, but it’s, like, I don’t know, maybe 10 or 20 vehicles on day one. And watch it carefully. They scale it up rapidly after that. So, we want to make sure that you’re paying very close attention the first time this happens. But, yeah, you will be able to — end of end of June or July, just go to Austin and order a Tesla for autonomous drive.”

While the June 1st date of the Robotaxi launch is extremely speculative, Tesla seems convinced that its vehicles could already handle this task. It would be something to see them come through on this date, especially on the first day of the month.
