SpaceX’s fifth Falcon Heavy launch on track for Sunday liftoff

Published

on

Update: SpaceX’s fifth Falcon Heavy launch is on track to launch as early as 5:56 pm EST (22:56 UTC), Sunday, January 15th. Tune in below around 5:40 pm EST (22:40 UTC) to watch the potentially spectacular launch live.

If Falcon Heavy does launch shortly after sunset, it could put on a spectacular show, lighting up the twilight skies for hundreds of miles up and down the East Coast.

The fifth Falcon Heavy rolled out of SpaceX’s Kennedy Space Center Pad 39A integration hangar on January 9th and went vertical early on January 10th. 12 hours later, it was loaded with ~1500 tons (~3.3 million lbs) of liquid oxygen and kerosene propellant and ignited for about eight seconds. SpaceX uses static fire tests more liberally than most other launch providers to try to ensure that all systems – propulsion included – are cooperating before liftoff.

At full throttle, Falcon Heavy Block 5’s 27 Merlin 1D engines – nine per Falcon 9-derived booster – can produce 2326 tons (5.13 million lbf) of thrust at sea level, making it the most powerful privately-developed rocket in history. In terms of performance, Falcon Heavy is the fifth most capable rocket ever built and is second only to NASA’s Space Launch System (SLS) today. While the records of N1, Saturn V, and Energia still stand, all three were retired decades ago.

As is the norm for a rocket with as little experience as Falcon Heavy, SpaceX conducted the static fire test without the USSF-67 payload installed. Like USSF-44, a virtually identical Falcon Heavy launch with similar payloads that launched on November 1st, 2022, SpaceX needs to roll the USSF-67 rocket back to the hangar for fairing installation. During USSF-44, SpaceX took approximately 110 hours to go from static fire to liftoff.

USSF-67’s static fire occurred about 100-104 hours before its scheduled liftoff, meaning that SpaceX only needs to be about 5% more efficient to be ready to launch on Saturday, January 14th. Assuming Falcon Heavy returns to the hangar and rolls back to the pad about as quickly as USSF-44, the odds of a Saturday launch are decent.

SpaceX’s second direct GEO launch

Like USSF-44, Falcon Heavy will sacrifice one of its three boosters (the center core) to launch USSF-67 directly to a circular geosynchronous orbit ~35,800 kilometers (~22,250 mi) above Earth’s surface. A satellite operating at GSO will never stray from the same region of Earth, making it useful for communications and surveillance. Getting there, however, can be exceptionally difficult.

“To simplify the rocket’s job, most GEO-bound satellites are launched into an elliptical geosynchronous or geostationary transfer orbit (GTO) and use their own propulsion to circularize that ellipse.

On a direct-to-GEO launch, the rocket does almost all of the work. After reaching a parking orbit in Low Earth Orbit (LEO), Falcon Heavy’s upper stage will complete a second burn to reach GTO. Then, while conducting a complex ballet of thermal management and tank pressure maintenance to prevent all of its cryogenic liquid oxygen (LOx) from boiling into gas and its refined kerosene (RP-1) from freezing into an unusable slush, the upper stage must coast ‘uphill’ for around five or six hours.

During that journey from 300 kilometers to 35,800 kilometers, the upper stage must also survive passes through both of Earth’s Van Allen radiation belts. At apogee, Falcon S2 must reignite its Merlin Vacuum engine for a minute or two to reach a circular GSO. Payload deployment follows soon after and could last anywhere from a few minutes to hours. Finally, to be a dutiful space tenant, Falcon’s upper stage must complete at least one more burn to reach a graveyard orbit a few hundred kilometers above GEO.”

The USSF-67 payload is mostly a mystery. Like USSF-44, it will carry a Northrop Grumman LDPE (Long Duration Propulsive EELV) with several unspecified rideshare payloads. LPDE is a transfer vehicle capable of deploying small satellites into customized orbits and hosting payloads for months in space.

The US Space Systems Command says [PDF] that “LDPE provides critical data to inform future Space Force programs” and that “the unique experiments and prototype payloads hosted on LDPE-3A [will] advance warfighting capabilities in the areas of on-orbit threat assessment, space hazard detection, and space domain awareness.”

Stay tuned for updates on USSF-67’s launch schedule and SpaceX’s official webcast.

Tesla Robotaxi test units spotted in new region ahead of launch

These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.

Tesla Robotaxi test units are being spotted in various new regions ahead of their launch in new states. Tesla is aiming to launch in at least a few new states in the coming months as it is ramping up hiring for the Robotaxi program and aiming to expand its ride-hailing service.

Already active in Austin, Texas, and the California Bay Area, Tesla is looking to expand its Robotaxi operations to new states. It’s had its eyes set on Nevada, Florida, and Arizona, which have seemed to have the most movement of the three prospects over the past month or so.

That trend is continuing.

Earlier this month, we reported on two Robotaxi units spotted testing with LiDAR rigs for ground truth validation in Gilbert, Arizona. Noted Cybertruck owner and enthusiast Greggertruck spotted the two units traveling on a highway.

Tesla Robotaxi testing in Arizona is ramping up quickly

Now, those same two units, or at least they appear to be, were spotted in Scottsdale, which is also a suburb of Phoenix, like Gilbert is, with the same LiDAR rigs:

These validation units are used to gain additional data for Tesla’s internal use, or even potentially for regulatory purposes that the company can share with agencies that will eventually grant a license to operate Robotaxi in the state.

Tesla is not a company that utilizes LiDAR for its everyday self-driving efforts, as it has utilized only cameras for the past several years.

Tesla Vision, as the company calls it, is what CEO Elon Musk feels is needed to achieve a fully autonomous network of vehicles, which will eventually need zero supervision for passenger transportation.

LiDAR is utilized by other companies, like Waymo, but Tesla has maintained that it is not necessary for several years. Musk has called it a “crutch” for achieving the proper self-driving tech, and the company only uses it for an additional bit of data.

Tesla has been operating its Robotaxi service in Austin since late June, and it has expanded its service area in the city to nearly 300 square miles, with its most recent expansion occurring earlier this week.

Tesla’s popular side business is going to get bigger, Elon Musk says

It took several years to get the Diner developed, built, and opened. On July 21, Tesla launched the Diner to the public at 4:20 p.m. local time (of course), after years of development. Musk first offered the idea of a drive-in Supercharger Diner back in December 2018.

Tesla will open two new Diner locations in the United States after its first location in Los Angeles has been a raging success, as it is constantly packed and serving food for 24 hours a day, every day.

Tesla CEO Elon Musk said that the initial Diner location on Santa Monica Boulevard is “going well,” and based on reviews and its constant out-the-door lines, it is safe to say it has been a major outlet of interest for people in the area.

It features two massive movie screens, a menu that is locally sourced and has been created by a world-class chef, and Supercharging for EVs. It truly is the perfect stop for those who are hungry, need entertainment, or need a quick charge.

So far, Tesla has not released too many details on the success of the restaurant, but it did state in a graphic for its Q3 Supercharging stats that it sold roughly 50,000 burgers at the Diner in Q3, roughly 715 each day. Burgers are not the only thing on the menu, either.

With how well it has gone, Musk is now considering the possibility of new locations that are notable to Tesla, including Austin and Palo Alto.

On Friday, Musk revealed he believes it “probably makes sense to open one” near Gigafactory Texas and Engineering HQ in Palo Alto:”

By 2023, Tesla had secured building permits and broken ground on the site in September of that year.

Since its launch, it has been a popular hotspot for Tesla fans and others to visit, although it has attracted unwanted attention from protestors as well.

They look hungry. If they walked inside and ordered some food, maybe they’d stop yelling into microphones and threatening Musk.

Elon Musk’s AI empire grows as xAI leases Palo Alto space near Tesla

The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area.

Elon Musk’s artificial intelligence startup, xAI, is expanding its Silicon Valley footprint, leasing roughly 105,000 square feet of office space at Palo Alto’s Page Mill Center, just blocks away from Tesla’s engineering complex.

Musk’s deepening Silicon Valley footprint

People familiar with the matter have informed the San Francisco Business Times that xAI’s lease at Page Mill Center may already have been finalized, adding to the company’s existing headquarters at 1450 Page Mill Road. The two offices share a parking lot, reflecting Musk’s strategy of consolidating his ventures. Tesla’s engineering hub is also just a few blocks away.

The new offices form a growing cluster of Musk-led companies in the heart of the Valley and come as xAI has listed over 250 job openings. These include listings for engineers, designers, and technical staff, among others. 

xAI’s aggressive hiring push hints at rapid scaling, which makes quite a lot of sense considering the company’s ambitious projects. xAI oversees the large language model Grok and other AI initiatives such as the newly launched Grokipedia, and the startup has also acquired the social media platform X. Real estate owner Hudson Pacific Properties, the owners of Page Mill Center, have so far declined to comment.

AI demand and Silicon Valley’s office rebound

Silicon Valley’s office market, long subdued by remote work trends, is seeing renewed activity from AI firms. Hudson Pacific told investors this summer that tenant demand has reached a three-year high, with over half of new leases driven by artificial intelligence companies. Vacancy rates have now fallen for four straight quarters to 16.6% as well, CBRE reported.

The expanding footprint of Elon Musk’s companies in Palo Alto bodes well for the CEO’s plans in the area. Musk, after all, has previously butted heads with officials, resulting in his two biggest ventures, electric vehicle maker Tesla and private space company SpaceX, officially relocating their headquarters to Texas.
