Two expeditions, two spacewalks, 322 days in space.

NASA has teamed up with Eric Schmidt's Relativity Space for a 2028 Martian mission.

Underneath an Apennine massif, below the Jinping Mountains of Sichuan, and at the bottom of a South Dakota mine, there is a cosmic hunt afoot. Isolated deep beneath these rocky shields, massive detectors filled with liquid xenon aim to make the first direct detections of dark matter, the long-sought invisible substance whose gravity has sculpted…

Relativity Space—a rocket maker acquired by former Google executive chair Eric Schmidt last year after stumbling on the path to orbit—might just beat SpaceX to Mars.

The former Sequoia Capital leader is filling an "existing vacancy" on SpaceX's board, days after the company went public in the largest IPO ever.

"Space Launch Complex-6 represents six decades of American innovation."

The funny-sounding name offers new insights into galaxy formation.

SpaceX's valuation has increased by $1 trillion since its shares started trading on Friday.

TechCrunch has followed SpaceX's start, struggles, and successes from the early days. And we're here for what happens next too. This package of SpaceX IPO coverage includes who stands to win (and maybe some who won't), pre-IPO deals, and what's tucked inside its S-1 registration document.

SpaceX's valuation has increased by $1 trillion since its shares started trading on Friday.

The deal is supposed to help SpaceX's struggling AI division. The company told IPO investors it sees a $26 trillion addressable market in AI.

In sandbox runtimes, "isolation" is the core requirement. qwrap (based on bwrap user namespace) and Container (podman/docker) are two mainstream backends. They solve the same problem — running code in a restricted environment — but take completely different paths. This article uses extensive analogies to help you understand the similarities and differences. Building Intuition: Two Ways to "Lock the Door" Imagine you need to confine someone you don't fully trust in a room to do work: qwrap approach : In your existing house, you put up a partition to wall off a corner, leaving only a small window to pass materials through. The walls are still the original walls, the floor is still the original floor, but the person can only see what's inside the partition. Container approach : You build a shipping container with its own independent power, water, and ventilation systems. Put the person inside, close the door. They feel like they're in a complete little house, completely unaware of what's outside. This is the most fundamental difference: qwrap is lightweight view isolation, Container is complete environment encapsulation . What is qwrap (bwrap user namespace) qwrap uses bubblewrap (bwrap) under the hood, a sandboxing tool that leverages Linux user namespaces. How it Works Host filesystem ├── /usr/bin/python3 ← Host's Python ├── /home/user/project/ ← User project └── /tmp/secrets/ ← Sensitive files qwrap sandbox view (what the process sees) ├── /usr/bin/python3 ← bind-mounted in, read-only ├── /workspace/ ← Only the project directory is exposed └── (/tmp/secrets/ doesn't exist) ← Completely invisible Key mechanisms: User Namespace : The process thinks it's root, but actually maps to an unprivileged user on the host Mount Namespace : Only bind-mounts necessary directories in, everything else is invisible No images, no layers, no network namespace (unless explicitly configured) Analogy: VPN Split Tunneling qwrap is like split-tunneling rules on your phone — you're not wrap

Isar Aerospace is not hurting for money, but it is sorely lacking in the currency of flight experience.

The rocket's breakup likely generated 100 to 150 new pieces of space junk.

SpaceX's IPO underwriters maxed out their share purchases, adding to an already historic amount of money raised.

This has been a persistent, behind-the-scenes dispute between NASA and Roscosmos.

In April, for the first time ever, an Earth observation satellite found what it was looking for, all on its own.

Startups are trying to "ride that SpaceX IPO wave."
