Here's what to expect from the fiery, 14-minute return of Artemis II

Here's what to expect from the fiery, 14-minute return of Artemis II

Death, taxes, and the gravitationally bound return of the Artemis II mission on Friday evening. These are the only certainties in life.

Even if the four astronauts on board the Orion spacecraft discovered a serious flaw in their spacecraft today—and to be clear, from recent images reviewed by NASA experts, everything looks just fine—there is no chance of significantly altering the Artemis II mission’s inexorable return through Earth’s atmosphere on Friday. They're coming back one way or another.

Splashdown is predicted to occur at 8:07 pm ET (00:07 UTC Saturday), a few hundred miles off the coast of Southern California. In large and important ways, this is the most critical phase of the lunar flight. Here, then, is what to expect later today.

Pro-Iran Explosive Media trolls Trump with AI-generated Lego cartoons

Pro-Iran Explosive Media trolls Trump with AI-generated Lego cartoons

Minutes after President Donald Trump announced that he would not wipe out “a whole civilization” on Tuesday evening, a team of self-described young Iranian activists jumped into action.

Members of the group known as Explosive Media were putting the finishing touches on their latest AI-generated, Lego-inspired Trump video. The video features a Trump mini-figure colluding with leaders from Gulf states, Iranian officials pressing a big red button labeled “back to the stone age,” and Trump throwing a chair at US generals.

This was the latest of more than a dozen videos the pro-Iran group has released since the beginning of the war in February, many of which have racked up millions of views on mainstream platforms. While Iranian government accounts have posted Lego-style videos in the past, Explosive Media’s content is more sophisticated and scripted. And it's produced by a team of young pro-Iranian creators who appear deeply knowledgeable about the Internet and American culture. Already some critics have alleged the group has ties to the Iranian government.

Dad stuck in support nightmare after teen lied about age on Discord

Dad stuck in support nightmare after teen lied about age on Discord

Brady Frey did not realize that his daughter lied about her age when she set up her Discord account. He only found out after her account got hacked and he got trapped in a spiraling support nightmare while trying to stop the hacker from targeting dozens of her young friends with financial extortion scams.

When Frey's daughter signed up for Discord, she was 12 and technically not old enough to have an account. But like many kids who, regulators have found, commonly lie about their age to access social media platforms, she didn't want to wait another year to join her friends on the messaging app. Hiding her age, she created an account that listed her as over 18 years old.

Now 13, the teen had been happily using the app for months when she suddenly got locked out of her account after clicking on a link from an attacker posing as Discord support. Since she didn't enable two-factor authentication, the attacker was able to commandeer the account. Frey only found out what was happening when the attacker asked the teen to share her parents' banking information if she wanted to get her account back.

Rocket Report: Chinese version of Falcon 9 fails; Artemis depends on rapid heavy lift

Rocket Report: Chinese version of Falcon 9 fails; Artemis depends on rapid heavy lift

Welcome to Edition 8.36 of the Rocket Report! Thank you for your indulgence of our missing the report last week, as we focused on the launch and progress of the Artemis II mission. And we are so thrilled it has been going smoothly, with brilliant imagery of the far side of the Moon. Of course, arguably the most difficult part of the flight remains ahead of the crew and Orion spacecraft: atmospheric reentry on Friday evening. We will, of course, have full and continuing coverage for you.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Alpha rocket may launch offshore. Seagate Space Corporation announced on Monday a "memorandum of understanding" with Firefly Aerospace to explore the development of an offshore launch platform that enables a sea-based launch capability for the Alpha rocket. Seagate Space said it will work closely with Firefly to mature the design of an integrated offshore launch system capable of supporting Alpha.

Orion helium leak no threat to Artemis II reentry but will require redesign

Orion helium leak no threat to Artemis II reentry but will require redesign

Apart from pesky issues with the spacecraft's toilet and waste disposal system, most of the Artemis II mission has proceeded like clockwork. NASA has made few changes to the flight plan since the launch of the lunar flyby mission on April 1.

But ground controllers revamped the timeline Wednesday as the Artemis II astronauts zoomed toward Earth after a close encounter with the Moon earlier this week. The four astronauts were supposed to take manual control of their Orion spacecraft, named Integrity, for a piloting demonstration Wednesday night.

Instead, mission managers canceled the demo to make time for an additional test of the ship's propulsion system. The goal was to gather data on a "small leak" of helium gas, which Orion uses to push propellant through a series of tanks and pipes to feed the spacecraft's rocket engines, said Jeff Radigan, NASA's lead flight director for the Artemis II mission.

RFK Jr. rewrites CDC panel's charter, opening door to anti-vaccine quacks

RFK Jr. rewrites CDC panel's charter, opening door to anti-vaccine quacks

As expected, anti-vaccine Health Secretary Robert F. Kennedy Jr. has significantly rewritten the charter for a federal vaccine advisory panel. The edits give him more power to appoint his like-minded allies as federal advisors, shift the panel's focus to alleged vaccine injuries and risks, and welcome fringe groups and anti-vaccine organizations to the Centers for Disease Control and Prevention.

On Monday, a notice in the Federal Register indicated Kennedy renewed the charter for the CDC's Advisory Committee on Immunization Practices (ACIP), which is done every two years, with the last term having ended April 1. But instead of the usual humdrum renewal process, the notice on Monday indicated big changes were coming to the defining document of the panel, which heavily influences federal vaccine policy that, in turn, influences state requirements and insurance coverage.

The new charter, published Thursday, reveals new responsibilities that redirect advisors toward topics and terms dear to anti-vaccine activists. For instance, ACIP members will now be responsible for "considering analysis of cumulative effects of vaccines and their constituent components." This wording echoes explicit goals of Kennedy's anti-vaccine allies, who aim to pin complex conditions—such as allergies, autism, and neurodevelopmental conditions—on combinations of vaccinations or common ingredients in those shots, such as aluminum adjuvants. This is a pivot from anti-vaccine activists' earlier attacks that focused on individual vaccines, such as the false, fraudulent claim that the measles vaccine is linked to autism—a claim that has been roundly debunked by dozens of high-quality studies.

AI on the couch: Anthropic gives Claude 20 hours of psychiatry

AI on the couch: Anthropic gives Claude 20 hours of psychiatry

The AI company Anthropic released a 244-page "system card" (PDF) this week describing its newest model, Claude Mythos. The model is "our most capable frontier model to date," the company says, and supposedly is so good that Anthropic has decided "not to make it generally available." (The company claims that Mythos is too good at finding unknown cybersecurity bugs, and so the model is only being released to select companies like Microsoft and Apple for now.)

Whatever the truth of this claim, the system card is a fascinating document. Anthropic is well-known as one of the more "AI might be conscious!" companies in the industry, and its new system card claims that as models become more powerful, "It becomes increasingly likely that they have some form of experience, interests, or welfare that matters intrinsically in the way that human experience and interests do."

The company isn't sure about this, it makes clear, but it says that "our concern is growing over time."
