SpaceX has won a lucrative contract to provide the US military with a means of distributing space-based sensing and targeting data, forming the "backbone" of a rearchitected network after separate Pentagon initiatives stalled, officials announced Tuesday.

Space Systems Command, the Space Force's primary procurement and acquisition center, announced the $2.29 billion firm-fixed-price agreement, confirming long-simmering reports that the Pentagon was likely to tap SpaceX for a new communications network in low-Earth orbit. SpaceX's selection for the Space Data Network (SDN) Backbone contract "accelerates the delivery of a resilient, high-speed communications network in space," Space Systems Command said in a statement.

The network will be based on technology originally developed for SpaceX's Starlink global Internet constellation. SpaceX already builds and launches specially designed satellites, called Starshield, for military applications. The SDN Backbone network in low-Earth orbit (LEO) will presumably use the Starshield platform.

SpaceX launched the first test flight of its upgraded Starship rocket and Super Heavy booster Friday, with mostly positive results.

The powerful rocket, propelled by 33 methane-fueled main engines, climbed away from SpaceX's Starbase launch facility in South Texas at 5:30 pm CDT (6:30 pm EDT; 22:30 UTC) Friday. Within a few seconds, the 408-foot-tall (124-meter) rocket, the largest ever built, cleared the launch tower and turned onto an eastward heading over the Gulf of Mexico.

Starship splashed down on target in the Indian Ocean a little more than an hour later to conclude the first flight of the latest version of SpaceX's stainless-steel mega-rocket. Starship V3 fared better on its debut than the first flights of Starship V1 and V2 in 2023 and 2025. Both past versions of Starship broke apart during launch on their inaugural flights.

Paleontologists in Argentina have identified a previously unknown species of unenlagiid dinosaur that stalked freshwater wetlands during the Late Cretaceous epoch, adding to evidence that some dinosaurs specialized in catching fish.

Most of the Steam Deck imitators on the market right now use AMD silicon, specifically the Ryzen Z-series chips. These are the same chips AMD makes for regular laptops, but with different power settings better suited to a compact handheld system. There are handhelds based on Intel silicon (MSI’s Claw is the main one), but Intel hasn’t yet tried making silicon marketed specifically for that purpose.

Today, the company is throwing its hat in the ring with two Intel Arc G-series processors, which will allow gaming handhelds to leverage the company's genuinely quite good Arc B-series integrated GPUs. Intel says that several Arc G-series handhelds will arrive "starting in June 2026, with broader availability throughout the year." These systems will include a new MSI Claw model, a Predator Atlas 8 from Acer, and a device from OneXPlayer.

Intel normally uses its "Arc" branding for integrated and dedicated GPUs, but in this case, the "Arc" brand encompasses the entire chip, including the CPU, GPU, NPU, and other components.

Activists had sued in a bid to secure her the fundamental human right to bodily liberty. Zoo officials said she was well cared for and called the lawsuit frivolous.

Valve's Steam Deck handheld has been largely unavailable to buy since mid-February, a victim of the RAM and storage shortages that have been driving up prices for most consumer tech since the fall of 2025. The good news is that the Deck is back in stock on Valve's site and ready to ship in three to five days; the bad news is that it appears to have returned because somebody wished for it on a monkey's paw.

The 512GB version of the OLED Steam Deck now sells for a whopping $789, $240 more than its previous $549 price. The 1TB version (which also includes an anti-glare screen coating, a slightly nicer case, and an "exclusive startup movie and keyboard theme") will now run you $949, a $300 increase from its old $649 price. The old $399 base model with 256GB of storage and the older LCD screen has been discontinued, though this had been announced well before these price increases took effect.

These prices are particularly hard to swallow for a nearly 3-year-old revision of an over-4-year-old handheld PC. If there's a saving grace for Valve, it's that most competing handhelds from the likes of Asus and Lenovo are also pushing or exceeding that $1,000 mark. Of the Deck's major competitors, only the $600 Asus ROG Xbox Ally (and its AMD Ryzen Z2 A processor, which is very similar to the Deck's semi-custom AMD chip) is significantly cheaper than the Steam Deck.

The ways it set up its board and Mr. Musk’s pay appear to benefit him at the expense of other shareholders, corporate governance experts said.

Outrage as leaked documents reveal mining giant’s backsliding on commitments to slash emissions

• Adam Morton: Big Mining gets a $4bn tax break to use fossil fuel. It’s a strange way to tackle emissions

The independent senator David Pocock says leaked BHP documents show that the mining giant is “laughing” at Australia’s key climate policy while pocketing hundreds of millions of dollars through a generous diesel tax break.

An exclusive investigation based on documents leaked to by the Guardian and the ABC show BHP has scrapped a project to significantly reduce global emissions, delayed vast renewables projects in the Pilbara and war-gamed options to push the electrification of its polluting diesel truck and train fleets into the next two decades.

California truckers have expressed strong interest in the Tesla Semi because it costs much less and can travel further on a charge than electric trucks sold by established manufacturers.

Security researcher Brian Krebs brings us the news that America's Cybersecurity & Infrastructure Agency (CISA) has had a large store of plaintext passwords, SSH private keys, tokens, and "other sensitive CISA assets" exposed in a public GitHub repo since at least November 2025.

The now-offline public repo—named, somewhat aspirationally, "Private-CISA"—was brought to Krebs' attention by GitGuardian's Guillaume Valadon, who was alerted to the repo's presence by GitGuardian's public code scans. Krebs says that Valadon approached him after receiving no responses from the Private-CISA repo's owner.

In an email to Krebs, Valadon claimed that the repo's commit logs show that GitHub's default protections against committing secrets—protections designed to protect unwitting or unskilled developers against exactly this kind of stupidness—had been disabled by the repo's administrator.

Daemon Tools, a widely used app for mounting disk images, has been backdoored in a monthlong compromise that has pushed malicious updates from the servers of its developer, researchers said Tuesday.

Kaspersky, the security firm reporting the supply-chain attack, said it began on April 8 and remained active as of the time its post went live. Installers that are signed by the developer’s official digital certificate and downloaded from its website infect Daemon Tools executables, causing the malware to run at boot time. Kaspersky didn’t explicitly say so, but based on technical details, the infected versions appear to be only those that run on Windows. Versions 12.5.0.2421 through 12.5.0.2434 are affected. Neither Kaspersky nor developer AVB could be contacted immediately for additional details.

Hard to defend against

Infected versions contain an initial payload that collects MAC addresses, hostnames, DNS domain names, running processes, installed software, and system locales. The malware sends them to an attacker-controlled server. Thousands of machines in more than 100 countries were targeted. Out of the many machines infected, about 12 of them, belonging to retail, scientific, government, and manufacturing organizations, have received a follow-on payload—an indication that the supply-chain attack targets select groups.

Servers operated by Ubuntu and its parent company Canonical were knocked offline on Thursday morning and have remained down ever since, a situation that’s preventing the OS provider from communicating normally following the botched disclosure of a major vulnerability.

Attempts to connect to most Ubuntu and Canonical webpages and download OS updates from Ubuntu servers have consistently failed over the past 24 hours. Updates from mirror sites, however, have continued to work normally. A Canonical status page said: “Canonical’s web infrastructure is under a sustained, cross-border attack and we are working to address it.” Other than that, Ubuntu and Canonical officials have maintained radio silence since the outage began.

A decades-long scourge

A group sympathetic to the Iranian government has taken credit for the outage. According to posts on Telegram and other social media, the group is responsible for a DDoS attack using Beam, an operation that claims to test the ability of servers to operate under heavy loads but, like other “stressors,” are, in fact, fronts for services miscreants pay for to take down third-party sites. In recent days, the same pro-Iran group has taken credit for DDoSes on eBay.
