Around noon EST on Thursday, March 17th, the high bay doors of NASA’s vast Vehicle Assembly Building (VAB) opened, revealing the first fully assembled Space Launch System (SLS) rocket and Orion spacecraft.

About six hours later, the massive rocket departed the VAB for the first time ever and began a four-mile (6.4 km) journey to Pad 39B atop Crawler-Transporter 2. This is the first time a Moon rocket has rolled out of NASA’s Vehicle Assembly Building since Saturn V headed to Pad 39A for Apollo 17 in 1972.

Crawler-Transporter 2 is a building-sized vehicle responsible for carrying NASA rockets – and their even more massive ‘mobile launch platforms’ – from the assembly building to the launch pad. The 6.6-million-pound (~3000 ton) vehicle has a top speed of two miles per hour (~3.2 km/h) while unloaded and one mile per hour (~1.6 km/h) while loaded and is designed to carry a payload of up to 18 million pounds (~8100 tons). The crawler ultimately took about 11 hours to transport SLS, Orion, and MLP-1 to Launch Complex 39B (LC-39B/Pad 39B).

Once the rocket and MLP-1 are fully installed on Pad 39B and the crawler has moved a safe distance away, SLS will be put through its first series of fully integrated tests, culminating in a wet dress rehearsal (WDR) as few as two weeks from now. Once the wet-dress is complete, SLS will be rolled back to the VAB for final launch preparations, including final Orion spacecraft processing, flight software updates. the identification and the repair of any issues found or wear generated during testing.

SLS is comprised of a core stage (CS-1), upper stage (the Interim Cryogenic Propulsion Stage or ICPS), two solid rocket boosters (SRBs), an incomplete but spaceworthy Orion spacecraft, and a new mobile launch platform (MLP-1). This particular vehicle will be responsible for Artemis-1, an uncrewed test flight that will attempt to inject Orion into orbit around the Moon. While most of the spacecraft’s systems are in place, Artemis 1’s Orion will have no life support or environmental control hardware installed and also lacks a docking adapter.

NASA and its SLS/Orion contractors have subcontracted parts of the rocket and spacecraft’s development to more than 1,100 companies spread across the US, as well as every NASA center. SLS and Orion prime contractors include Boeing, Aerojet Rocketdyne, Northrup Grumman, and the United Launch Alliance. Once completed and qualified, all hardware was shipped to Kennedy Space Center, where the SLS rocket was then fully assembled inside the VAB. All Artemis 1 hardware arrived at KSC by the end of April 2021.

NASA says SLS’ launch debut is now expected to occur no earlier than (NET) May or June 2022. However, given the program’s history of delays, particularly surrounding major integrated testing, it’s likely that this stage of SLS testing will take longer than expected, so launch dates should only be treated as placeholders until the rocket has completed prelaunch testing and been inspected and recertified back inside the VAB.

Tesla has crossed another major charging milestone by officially installing its 75,000th Supercharger stall worldwide. The electric vehicle maker chose South Hobart, Tasmania, as the commemorative location of its 75,000th Supercharger. 

Tesla’s 75,000th Supercharger

Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, TAS 7004, as noted in a techAU report. The location features four next-generation V4 Superchargers, which are built with longer cables that should make it easy even for non-Teslas to use the rapid charger. The site also includes simplified payment options, aligning with Tesla’s push to make V4 stations more accessible to a broader set of drivers.

For Tasmanian EV owners, the installation fills an important regional gap, improving long-distance coverage around Hobart and strengthening the area’s appeal for mainland travelers traveling by electric vehicle. Similar to other commemorative Superchargers, the 70,000th stall is quite special as it is finished in Glacier Blue paint. Tesla’s 50,000th stall, which is in California, is painted a stunning red, and the 60,000th stall, which is in Japan, features unique origami-inspired graphics.

Accelerating Supercharger milestones

The Tesla Supercharger’s pace of expansion shows no signs of slowing. Tesla celebrated its 70,000th stall at a 12-stall site in Burleson, Texas late June 2025. Just eight months earlier, Tesla announced that it had celebrated the buildout of its 60,000th Supercharger, which was built in Enshu Morimachi, Shizuoka Prefecture, Japan.

Tesla’s Supercharger Network also recently received accolades in the United Kingdom, with the 2025 Zapmap survey naming the rapid charging system as the Best Large EV Charging Network for the second year in a row. Survey respondents praised the Supercharger Network for its ease of use, price, and reliability, which is best-in-class. The fact that the network has also been opened for non-Teslas is just icing on the cake.

Luminar-Volvo breakdown deepens as lidar maker warns of potential bankruptcy

The automaker stated that Luminar failed to meet contractual obligations.

Luminar’s largest customer, Volvo, has canceled a key five-year contract as the lidar supplier warned investors that it might be forced to file for bankruptcy. The automaker stated that Luminar failed to meet contractual obligations, escalating a dispute already unfolding as Luminar defaults on loans, undergoes layoffs, and works to sell portions of the business.

Volvo pulls back on Luminar

In a statement to TechCrunch, Volvo stated that Luminar’s failure to deliver its contractual obligations was a key driver of the cancellation of the contract. “Volvo Cars has made this decision to limit the company’s supply chain risk exposure and it is a direct result of Luminar’s failure to meet its contractual obligations to Volvo Cars,” Volvo noted in a statement.

The rift marked a notable turn for the two companies, whose relationship dates back several years. Volvo invested in Luminar early and helped push its sensors into production programs, while Luminar’s technology bolstered the credibility of Volvo’s safety-focused autonomous driving plans. Volvo’s partnership also supported Luminar’s 2020 SPAC listing, which briefly made founder Austin Russell one of the youngest self-made billionaires in the industry.

Damaged Volvo relations

The damaged Volvo partnership comes during a critical period for Luminar. The company has defaulted on several loans and warned investors that bankruptcy remains a possibility if restructuring discussions fall through. To conserve cash, Luminar has cut 25% of its workforce and is exploring strategic alternatives, including partial or full asset sales. 

One potential buyer is founder Austin Russell, who resigned as CEO in May amid a board-initiated ethics inquiry. The company is also the subject of an ongoing SEC investigation.

Luminar, for its part, also noted in a filing that it had “made a claim against Volvo for significant damages” and “suspended further commitments of Iris” for the carmaker. “The Company is in discussions with Volvo concerning the dispute; however, there can be no assurance that the dispute will be resolved favorably or at all,” the lidar maker stated.

Elon Musk says he’s willing to help Apple overhaul Siri by integrating xAI’s Grok 4.1, igniting widespread excitement and speculations about a potential collaboration between the two tech giants. 

Siri, one of the first intelligent AI assistants in the market, has become widely outdated and outperformed by rivals over the years.

Musk open to an Apple collaboration

Musk’s willingness to team up with Apple surfaced after an X user suggested replacing Siri with Grok 4.1 to modernize the AI assistant. The original post criticized Siri’s limitations and urged Apple to adopt a more advanced AI system. “It’s time for Apple to team up with xAI and actually fix Siri. Replace that outdated, painfully dumb assistant with Grok 4.1. Siri deserves to be Superintelligent,” the X user wrote.

Musk quoted the post, responding with, “I’m down.” Musk’s comment quickly attracted a lot of attention among X’s users, many of whom noted that a Grok update to Siri would be appreciated because Apple’s AI assistant has legitimately become terrible in recent years. Others also noted that Grok, together with Apple’s potential integration of Starlink connectivity, would make iPhones even more compelling.

Grok promises major Siri upgrades

The enthusiasm stems largely from Grok 4.1’s technical strengths, which include stronger reasoning and improved creative output. xAI also designed the model to reduce hallucinations, as noted in a Reality Tea report. Supporters believe these improvements could address Apple’s reported challenges developing its own advanced AI systems, giving Siri the upgrade many users have waited years for.

Reactions ranged from humorous to hopeful, with some users joking that Siri would finally “wake up with a personality” if paired with Grok. Siri, after all, was a trailblazer in voice assistants, but it is currently dominated by rivals in terms of features and capabilities. Grok could change that, provided that Apple is willing to collaborate with Elon Musk’s xAI.
