Space Perspective could begin test flights of its privately owned capsule suspended under a high-altitude balloon within the next couple of months, the company's co-founder told Ars this week.

Florida-based Space Perspective released photos of its first completed test capsule Tuesday. The company will use this pressurized capsule, called Excelsior, for a series of test flights this year over the Atlantic Ocean just off the coast of Cape Canaveral. Taber MacCallum, Space Perspective's co-founder and chief technology officer, said employees have also finished fabricating the giant balloon that will lift the test capsule into the upper atmosphere for the first test flight.

The final piece of the puzzle is a ship, named Marine Spaceport Voyager, that Space Perspective will use to launch the balloon and capsule. This vessel is due to depart an outfitting facility in Louisiana in the next few weeks for a trip to Port Canaveral, Florida, where Space Perspective will load aboard the capsule and balloon. Then, perhaps in four to six weeks, ground teams will be ready for the system's first test flight, according to MacCallum.

iMessage is getting a major makeover that makes it among the two messaging apps most prepared to withstand the coming advent of quantum computing, largely at parity with Signal or arguably incrementally more hardened.

On Wednesday, Apple said messages sent through iMessage will now be protected by two forms of end-to-end encryption (E2EE), whereas before, it had only one. The encryption being added, known as PQ3, is an implementation of a new algorithm called Kyber that, unlike the algorithms iMessage has used until now, can’t be broken with quantum computing. Apple isn’t replacing the older quantum-vulnerable algorithm with PQ3—it's augmenting it. That means, for the encryption to be broken, an attacker will have to crack both.

Making E2EE future safe

The iMessage changes come five months after the Signal Foundation, maker of the Signal Protocol that encrypts messages sent by more than a billion people, updated the open standard so that it, too, is ready for post-quantum computing (PQC). Just like Apple, Signal added Kyber to X3DH, the algorithm it was using previously. Together, they’re known as PQXDH.

A sixth student at Florida's Manatee Bay Elementary School outside of Fort Lauderdale has a confirmed case of measles, health officials announced late Tuesday. However, health officials are not telling unvaccinated students who were potentially exposed to quarantine.

The school has a low vaccination rate, suggesting that the extremely contagious virus could spark a yet larger outbreak. But in a letter sent to parents late Tuesday, Florida Surgeon General Joseph Ladapo—known for spreading anti-vaccine rhetoric and vaccine misinformation—indicated that unvaccinated students can skip the normally recommended quarantine period.

The letter, signed by Ladapo, noted that people with measles can be contagious from four days before the rash develops through four days after the rash appears. And while symptoms often develop between 8 to 14 days after exposure, the disease can take 21 days to appear. As such, the normal quarantine period for exposed and unvaccinated people, who are highly susceptible to measles, is 21 days.

The University of Alabama at Birmingham (UAB) health system is halting in vitro fertilization treatment in the wake of a ruling by the state's Supreme Court on Friday that deemed frozen embryos to be "children," The ruling opens up anyone who destroys embryos to liability in a wrongful death lawsuit, according to multiple media reports.

The announcement—the first facility to report halting IVF services—is the much-feared outcome of Friday's ruling, which was widely decried by reproductive health advocates.

"We are saddened that this will impact our patients' attempt to have a baby through IVF, but we must evaluate the potential that our patients and our physicians could be prosecuted criminally or face punitive damages for following the standard of care for IVF treatments," UAB said a statement to media. The statement noted that egg retrieval would continue but that egg fertilization and embryo development are now paused.

The rocket company owned by Amazon founder Jeff Bezos, Blue Origin, has emerged as the sole finalist to buy United Launch Alliance.

The sale is not official, and nothing has been formally announced. The co-owners of United Launch Alliance (ULA), Lockheed Martin and Boeing, have yet to comment publicly on the sale of the company, which, until the rise of SpaceX, was the sole major launch provider in the United States. They declined again on Wednesday.

"Consistent with our corporate practice, Boeing doesn’t comment on potential market rumors or speculation," a Boeing spokesperson said.

Google went ahead with plans to launch Gemini for Workspace today. The big news is the pricing information, and you can see the Workspace pricing page is new, with every plan offering a "Gemini add-on." Google's old AI-for-Business plan, "Duet AI for Google Workspace," is dead, though it never really launched anyway.

Google has a blog post explaining the changes. Google Workspace starts at $6 per user per month for the "Starter" package, and the AI "Add-on," as Google is calling it, is an extra $20 monthly cost per user (all of these prices require an annual commitment). That is a massive price increase over the normal Workspace bill, but AI processing is expensive. Google says this business package will get you "Help me write in Docs and Gmail, Enhanced Smart Fill in Sheets and image generation in Slides." It also includes the "1.0 Ultra" model for the Gemini chatbot—there's a full feature list here. This $20 plan is subject to a usage limit for Gemini AI features of "1,000 times per month."

Gemini for Google Workspace represents a total rebrand of the AI business product and some amount of consistency across Google's hard-to-follow, constantly changing AI branding. Duet AI never really launched to the general public. The product, announced in August, only ever had a "Try" link that led to a survey, and after filling it out, Google would presumably contact some businesses and allow them to pay for Duet AI. Gemini Business now has a checkout page, and any Workspace business customer can buy the product today with just a few clicks.
