SpaceX Starship V3 Successfully Launches and Splashes Down

SpaceX completed the first launch and splashdown recovery of Starship V3. Elon Musk congratulated the team, saying they “scored a goal for humanity.” The mission carried approximately 45 tons of Starlink mass simulators, making it one of the heaviest payloads sent into orbit since the Soviet Polyus. NASA’s administrator also tweeted congratulations, stating “one step closer to the Moon, one step closer to Mars.” SpaceX livestreamed the entire launch, space flight, and ocean splashdown, with Starlink satellites providing real-time communication and streaming support. Gwynne Shotwell called it “an incredible first flight of a brand-new vehicle configuration.”

Anthropic Cybersecurity Project Uncovers Over 10,000 Vulnerabilities; Nearly Trillion-Dollar Funding Rumored

Anthropic’s Project Glasswing cybersecurity initiative, in collaboration with about 50 partners over the past month, used Claude Mythos Preview to discover over 10,000 high-severity or critical vulnerabilities in key software. Mozilla fixed 271 vulnerabilities after testing Firefox with an early version, while Cloudflare scanned approximately 2,000 bugs, 400 of which were high-risk. Anthropic scanned over 1,000 open-source projects, with the model identifying 23,019 vulnerabilities (6,202 high/critical), achieving a true positive rate of 90.6% after verification. However, Anthropic stated that current security measures are insufficient to prevent misuse of such models, so it will not publicly release Mythos-level models. Meanwhile, according to Bloomberg, Anthropic is nearing completion of over $30 billion in funding, with a valuation exceeding $900 billion (surpassing OpenAI), and an annualized revenue run rate expected to exceed $50 billion next month.

Claude Code Feishu Bridge Open-Sourced: Control Claude Code from Your Phone

Zara Zhang open-sourced the feishu-claude-code-bridge project, enabling a bridge between Feishu messages and the local Claude Code CLI. Users can directly converse with Claude Code within the Feishu client, supporting setting Workspace directories, reading CLAUDE.md and Skills, and also allowing Claude Code to create and edit Feishu documents in reverse. Baoyu detailed the operation method and noted that the architecture can be extended to connect other tools like Codex and Cursor. Notably, starting June 15, 2026, Claude subscription plans will bill separately for the use of claude -p and Agent SDK, while API users remain unaffected.

X product lead Nikita Bier stated that over the past month, the platform has identified a group of large accounts programmatically re-uploading content from smaller accounts to manipulate the revenue sharing program and bypass attribution. X is now identifying these posts and fully allocating views to the original creators. He recommends using the “Share Video” or “Quote” features when making insightful comments to ensure proper attribution.
