SpaceX competitor ULA readies for final launch of 30-year-old Delta II rocket

Published

on

Long-time SpaceX competitor United Launch Alliance (ULA) is nearly ready for the final launch of its Boeing subsidiary’s Delta II family of rockets, culminating a nearly 30-year history mostly dominated by routine success.

If completed without failure, the launch of NASA’s ICESat-2 satellite – built to track global ice-sheet variation with a huge space-based laser – will mark Delta II’s 100th consecutive success and the rocket’s 153rd fully successful launch overall, an immensely impressive and laudable achievement regardless of the vehicle’s lack of competitive advantage in the modern launch industry.

Shockingly tiny when compared with modern launch vehicles like Delta IV, Atlas V, and Falcon 9, Delta II measures roughly 39 meters (~128 ft) tall, 2.4 meters (8 ft) in diameter, and weighs 160 metric tons (~350,000 lb) when fully fueled, just over half as tall and significantly less than 30% as heavy as SpaceX’s Falcon 9.

Contracted by NASA in 2013, Delta II’s ICESat-2 launch cost the agency roughly $97 million (2013 USD), although the cost of launch has shrunk in relation to the satellite, which suffered at least $200 million of overruns and 12+ months of delays due to difficulties developing the spacecraft’s impressive space-based LIDAR system. For comparison, NASA contracted a Falcon 9 launch (for the TESS exoplanet observatory, launched in April 2018) from SpaceX for $87 million in 2016, while the USAF has secured several launch contracts with SpaceX for far more complex GPS satellite launches at a cost of almost exactly $97 million apiece.

Aging rockets, changing markets

Put simply, the contrast in capabilities offered for equivalent prices soundly demonstrates exactly why Delta II is being phased out. Although capable of better performance with a third upper stage and nine much larger solid rocket boosters (SRBs), that ‘Heavy’ variant of Delta II cost NASA an incredible $150 million per launch in 2009. For the versions of Delta II closer to $100 million per launch, the rocket is able to place 2500-3200 kg (5500-7000 lb) in low Earth orbit and not much at all to any higher energy destinations, which demand a third stage or a heavier rocket. At a comparable price (or much lower in SpaceX’s case), Atlas V and Falcon 9 are able to launch far larger payloads to far higher orbits.

This was by no means the case when Delta II debuted in 1989, and the McDonnell Douglas-built rocket readily earned its impressive reputation as a relatively reliable, capable, and (more or less) affordable launch vehicle compared alongside other rockets available in the ’90s. Delta II wound up as a ULA rocket (sort of) thanks to Boeing and McDonnell Douglas’ 1997 corporate merger, followed in 2006 by Lockheed Martin and Boeing’s cooperative formation of the United Launch Alliance. ULA thus operates Delta II, Delta IV, and Atlas V, all featuring multiple variants and very few distinguishing capabilities when compared amongst themselves.

The cost of maintaining all those highly duplicative rockets and unique factories and engineering expertise is fundamentally unnatural and reliant upon some sort of noncompetitive market forces (i.e. launch monopolies assured through “block buys” of multiple rockets from NASA and the US military), forces that have been mortally challenged by SpaceX’s reintroduction of competition to the American launch industry.

ICESat-2 is scheduled to launch on Delta II on Saturday, September 15th at 5:46 AM PDT/12:46 UTC. Stay tuned for more information on ICESat-2’s giant space LIDAR payload and mission goals, as well as Teslarati photographer Pauline Acalin’s photos of the fairly historic rocket launch.

Tesla reveals its Cybertruck light bar installation fix

Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.

Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.

Tesla recalls 6,197 Cybertrucks for light bar adhesive issue

The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”

Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.

Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:

The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.

However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”

The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.

This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.

Tesla is already expanding its Rental program aggressively

The program has already launched in a handful of locations, specifically, it has been confined to California for now. However, it does not seem like Tesla has any interest in keeping it restricted to the Golden State.

Tesla is looking to expand its Rental Program aggressively, just weeks after the program was first spotted on its Careers website.

Earlier this month, we reported on Tesla’s intention to launch a crazy new Rental program with cheap daily rates, which would give people in various locations the opportunity to borrow a vehicle in the company’s lineup with some outrageous perks.

Along with the cheap rates that start at about $60 per day, Tesla also provides free Full Self-Driving operation and free Supercharging for the duration of the rental. There are also no limits on mileage or charging, but the terms do not allow the renter to leave the state from which they are renting.

The program has already launched in a handful of locations, specifically, it has been confined to California for now. However, it does not seem like Tesla has any interest in keeping it restricted to the Golden State.

Job postings from Tesla now show it is planning to launch the Rental program in at least three new states: Texas, Tennessee, and Massachusetts.

The jobs specifically are listed as a Rental Readiness Specialist, which lists the following job description:

“The Tesla Rental Program is looking for a Rental Readiness Specialist to work on one of the most progressive vehicle brands in the world. The Rental Readiness Specialist is a key contributor to the Tesla experience by coordinating the receipt of incoming new and used vehicle inventory. This position is responsible for fleet/lot management, movement of vehicles, vehicle readiness, rental invoicing, and customer hand-off. Candidates must have a high level of accountability, and personal satisfaction in doing a great job.”

It also says that those who take the position will have to charge and clean the cars, work with clients on scheduling pickups and drop-offs, and prepare the paperwork necessary to initiate the rental.

The establishment of a Rental program is big for Tesla because it not only gives people the opportunity to experience the vehicles, but it is also a new way to rent a car.

Just as the Tesla purchasing process is more streamlined and more efficient than the traditional car-buying experience, it seems this could be less painful and a new way to borrow a car for a trip instead of using your own.

Elon Musk’s xAI gains first access to Saudi supercluster with 600k Nvidia GPUs

The facility will deploy roughly 600,000 Nvidia GPUs, making it one of the world’s most notable superclusters.

A Saudi-backed developer is moving forward with one of the world’s largest AI data centers, and Elon Musk’s xAI will be its first customer. The project, unveiled at the U.S.–Saudi Investment Forum in Washington, D.C., is being built by Humain, a company supported by Saudi Arabia’s Public Investment Fund. 

The facility will deploy roughly 600,000 Nvidia GPUs, making it one of the world’s most notable superclusters.

xAI secures priority access

Nvidia CEO Jensen Huang stated that the planned data center marks a major leap not just for the region but for the global AI ecosystem as a whole. Huang joked about the sheer capacity of the build, emphasizing how unusual it is for a startup to receive infrastructure of such magnitude. The facility is designed to deliver 500 megawatts of Nvidia GPU power, placing it among the world’s largest AI-focused installations, as noted in a Benzinga report.

“We worked together to get this company started and off the ground and just got an incredible customer with Elon. Could you imagine a startup company, approximately $0 billion in revenues, now going to build a data center for Elon? 500 megawatts is gigantic. This company is off the charts right away,” Huang said.

Global Chipmakers Join Multi-Vendor Buildout To Enhance Compute Diversity

While Nvidia GPUs serve as the backbone of the first phase, Humain is preparing a diversified hardware stack. AMD will supply its Instinct MI450 accelerators, which could draw up to 1 gigawatt of power by 2030 as deployments ramp. Qualcomm will also contribute AI200 and AI250 data center processors, accounting for an additional 200 megawatts of compute capacity. Cisco will support the networking and infrastructure layer, helping knit the multi-chip architecture together.

Apart from confirming that xAI will be the upcoming supercluster’s first customer, Musk also joked about the rapid scaling needed to train increasingly large AI models. He joked that a theoretical expansion one thousand times larger of the upcoming supercluster “would be 8 bazillion, trillion dollars,” highlighting the playful exaggeration he often brings to discussions around extreme compute demand.
