SpaceX Unveils Sweeping Starship V3 Upgrades

SpaceX has detailed major Starship V3 upgrades ahead of a launch targeted as early as May 19. The changes are meant to move Starship closer to its core goals: rapid reuse, Starlink deployment, orbital refueling, and eventually Moon and Mars missions. Longtime Slashdot reader schwit1 shares a report from Teslarati: Here is an explicit, broken-down list of the key changes, first starting with the changes to Super Heavy V3: - Grid Fin Redesign: Reduced from four fins to three. Each fin is now 50% larger and stronger, repositioned for better catching and lifting performance. Fins are lowered on the booster to reduce heat exposure during hot staging, with hardware moved inside the fuel tank for protection. - Integrated Hot Staging: Eliminates the old disposable interstage shield. The booster dome is now directly exposed to upper-stage engine ignition, protected by tank pressure and steel shielding. Interstage actuators retract after separation. - New Fuel Transfer System: Massive redesign of the fuel transfer tube -- roughly the size of a Falcon 9 first stage -- enables simultaneous startup of all 33 Raptors for faster, more reliable flip maneuvers. - Engine Bay/Thermal Protection: Engine shrouds removed entirely; new shielding added between engines. Propulsion and avionics are more tightly integrated. CO? fire suppression system deleted for a simpler, lighter aft section. - Propellant Loading Improvements: Switched from one quick disconnect to two separate systems for added redundancy and reduced pad complexity. Next, we have the changes to Starship V3: - Completely Redesigned Propulsion System: Clean-sheet redesign supports new Raptor startup, larger propellant volume, and an improved reaction control system while reducing trapped or leaked propellant risk. - Aft Section Simplification: Fluid and electrical systems rerouted; engine shrouds and large aft cavity deleted. - Flap Actuation Upgrade: Changed from two actuators per flap to one actuator with three motors for better redundancy, mass efficiency, and lower cost. - Faster Starlink Deployment: Upgraded PEZ dispenser enables quicker satellite release. - Long-Duration Spaceflight Capability: New systems for long orbital coasts, orbital refueling, cryogenic fluid management, vacuum-insulated header tanks, and high-voltage cryogenic recirculation. - Ship-to-Ship Docking + Refueling: Four docking drogues and dedicated propellant transfer connections added to support in-space refueling architecture. - Avionics Upgrades: 60 custom avionics units with integrated batteries, inverters, and high-voltage systems (9 MW peak power). New multi-sensor navigation for precision autonomous flight. RF sensors measure propellant in microgravity. ~50 onboard camera views and 480 Mbps Starlink connectivity for low-latency communications. "Believe it or not, there's more," writes schwit1. "Two years ago, the biggest and most powerful rocket ever flown was Starship V1. Last year, it was Starship V2. V3 is about to become the biggest and most powerful rocket ever flown -- but don't worry, the company already has plans for V4."

Musk Accused of 'Selective Amnesia', Altman of Lying As OpenAI Trial Nears End

An anonymous reader quotes a report from Reuters: A lawyer for Elon Musk hammered at the credibility of OpenAI CEO Sam Altman on Thursday, near the end of a trial over whether to hold the ChatGPT maker and its leaders responsible for allegedly transforming the nonprofit into a vehicle to enrich themselves. OpenAI's lawyers fought back, claiming the world's richest person waited too long to claim OpenAI breached its founding agreement to build safe artificial intelligence to benefit humanity, and couldn't claim he was essential to its success. "Mr. Musk may have the Midas touch in some areas, but not in AI," said William Savitt, a lawyer for OpenAI. "To succeed in AI, as it turns out, all Mr. Musk can do is come to court." The claims were made during closing arguments of a trial in the Oakland, California, federal court. [...] In his closing argument, Musk's lawyer Steven Molo told jurors that five witnesses, including Musk, former OpenAI board members and former OpenAI Chief ScientistIlya Sutskever, testified that Altman was a liar. Molo also noted that during cross-examination on Tuesday, Altman did not say yes unequivocally when asked if he was completely trustworthy and did not mislead people in business. "Sam Altman's credibility is directly at issue in this case," Molo said. "If you don't believe him, they cannot win." Molo accused OpenAI of wrongfully trying to enrich investors and insiders at the nonprofit's expense, and failing to prioritize AI's safety. He also challenged Brockman's goals for the business, citing Brockman'sstatementthat his own OpenAI stake was worth nearly $30 billion. "The arrogance, the lack of sensitivity, the failure to account for just common decency is really, really abhorrent." Musk also accused Microsoft, which invested $1 billion in OpenAI in 2019 and $10 billion in 2023, of aiding and abetting OpenAI's wrongful conduct. "Microsoft was aware of what OpenAI was doing every step of the way," Molo said. Sarah Eddy, another lawyer for the OpenAI defendants, accused Musk and his legal team in her closing argument of resorting to "sound bites and irrelevant false accusations." Eddy said by 2017, everyone associated with OpenAI -- including Musk, then still on its board -- knew it needed more money to fulfill its mission than it could raise as a nonprofit. "Mr. Musk wanted to turn OpenAI into a for-profit company that he could control," she said. "But the other founders refused to turn the keys of AGI (artificial general intelligence) over to one person, let alone Elon Musk."She also said if Musk truly believed AI should serve humanity, he would not have pushed to fold OpenAI into his electric car company Tesla, or made his rival xAI a for-profit company. Musk had a three-year statute of limitations to sue, and OpenAI's lawyers said his August 2024 lawsuit came too late because he knew several years earlier about OpenAI's growth plans. Eddy expressed disbelief that Musk claimed he did not read a four-page term sheet in 2018 discussing OpenAI's plan to seek outside investments. "One of the most sophisticated businessmen in the history of the world" wouldn't have "stuck his head in the sand," Eddy said. Savitt accused Musk of having "selective amnesia." Microsoft's lawyer Russell Cohen said in his closing statement that Microsoft wasn't involved in the key events of the case, and was "a responsible partner at every step." On Monday, the nine-person jury is expected to begin deliberating. The judge and lawyers will also return to court to discuss possible remedies if Musk wins, including how OpenAI should be restructured and what damages might be awarded. If Musk loses, there will be no remedies to consider.

UK Antitrust Regulator Is Officially Investigating Microsoft Office

The UK's Competition and Markets Authority is opening a formal investigation into whether Microsoft's bundling of Windows, Office, Teams, Copilot, and related products harms competition. Engadget reports: "Our aim is to understand how these markets are developing, Microsoft's position within them and to consider what, if any, targeted action may be needed to ensure UK organizations can benefit from choice, innovation and competitive prices," CMA Chief Executive Sarah Cardell said in a statement published by Reuters. She also stressed the importance of the investigation by noting that hundreds of thousands of UK residents use business software and Microsoft products. The organization will take a look into the company's cloud licensing practices. The CMA has stated that the inquiry will conclude by February. At that point, Microsoft could get slapped with a strategic market label. Microsoft says it's "committed to working quickly and constructively with the CMA to facilitate its review of the business software market." A strategic market designation doesn't automatically assume wrongdoing, but will give the CMA more leeway when conducting further interventions.
