Since the Lunar Trailblazer spacecraft launched in late February as a rideshare spacecraft along with a Falcon 9 launch, NASA has been providing a series of increasingly worrisome updates about the health of the small orbiter. Trailblazer appears to be spinning and out of contact with engineers back on Earth.

In an update published on Tuesday evening, the space agency acknowledged that a mission operations team at the California Institute of Technology is continuing its efforts to reestablish contact with the 200-kg spacecraft intended to orbit the Moon.

"Based on telemetry before the loss of signal last week and ground-based radar data collected March 2, the team believes the spacecraft is spinning slowly in a low-power state," the space agency said. "They will continue to monitor for signals should the spacecraft orientation change to where the solar panels receive more sunlight, increasing their output to support higher-power operations and communication."

Jeff Bezos has moved to introduce a tough Amazon-like approach to his rocket maker Blue Origin, as the world’s third-richest person seeks to revive a company that has lagged behind Elon Musk’s SpaceX.

The space company’s founder and sole shareholder has pushed to shift its internal culture with management hires from Amazon, while implementing policies akin to the ecommerce giant, including longer working hours and more aggressive targets.

Half a dozen current and former senior Blue Origin employees told the Financial Times that the billionaire had taken a prominent role in helping reset a company that has reached orbit only once, compared with SpaceX achieving the feat more than 450 times.

Apple’s first Mac Studio refresh in nearly two years is a welcome update, injecting fresh life into two computers that were still getting by with M2 chips. But the company took a bit of a strange approach to the update, giving an M4-series Max chip to the lower-end Studio but an M3 Ultra chip to the high-end model.

These processors are both performance upgrades from the M2 Max and M2 Ultra, and the M3 Ultra is so huge that it should have no trouble outrunning the M4 Max despite its slightly older CPU and GPU architecture. But it’s still a departure from past practice, where Apple would keep the Studio’s chip generation in lockstep.

When asked why the high-end Mac Studio was getting an M3 Ultra chip instead of an M4 Ultra, Apple told us that not every chip generation will get an “Ultra” tier. This is, as far as I can recall, the first time that Apple has said anything like this in public.

Apple announced its first Mac Studio updates in nearly two years today, a few months after bringing the M4 and M4 Pro chips to the Mac mini.

As before, Apple offers a lower-end and a higher-end configuration of the Mac Studio. The lower-end model is pretty much what you expect: It gives you the same M4 Max processor Apple introduced in the high-end MacBook Pro last year. It has up to 16 CPU cores (10 P-cores, 4 E-cores), up to 40 GPU cores, and a 16-core Neural Engine.

The $1,999 base model comes with 14 CPU cores (10 P-cores, 4 E-cores), 32 GPU cores, 36GB of RAM, and 512GB of storage. That model's RAM can't be upgraded until you step up to the fully-enabled M4 Max, which also gets you 48GB of RAM for $300. From there, the desktop can be upgraded with either 64GB or 128GB of RAM, same as the MacBook Pro.

As expected, Apple has officially refreshed its MacBook Air lineup with its M4 chip, the same silicon we've already seen in products like the MacBook Pro, the iMac, and the Mac mini. And in most ways, it's a straightforward update, with no major changes to the laptop's physical design, screen specs, keyboard, or ports.

The most important update is the price. The 13-inch M4 MacBook Air will start at $999, a $100 price cut compared to the M3 Air and the same price that Apple set for the M2 Air last year when the M3 models came out. The 15-inch model will also get a $100 cut, from $1,299 to $1,199. These baseline configurations still come with 16GB of RAM and 256GB of storage.

The M2 version will continue to be sold as a budget model in some countries, but the US isn't one of them. Apple will also continue to sell a cheaper version of the M1 MacBook Air through Walmart, which it has been doing since March 2024.
