It's happening—we're about 2 hours away from the Artemis II mission splashdown! Here's a timeline of what to expect.

When you think about it, Artemis II is really the ultimate "just circling back!"

What is the quantum ‘Ghost Murmur’ purportedly used in Iran? Scientists question CIA’s claim of long-range heartbeat detection Ghost Murmur was described as a futuristic CIA tool that could detect a heartbeat from vast distances. Physicists say the public story clashes with the basic limits of magnetic sensing

I would like to gently suggest that ramping up the already sky-high level of anxiety on here, especially for posters with outsize platforms, is not a great use of anyone's time or energy today.

Trump Slashed Science Funding. Now the U.S. Could Face a Costly Brain Drain.

A study in September by the Information Technology and Innovation Foundation, a Washington think tank, warned that without a reversal, the cuts to science could shrink the U.S. economy by nearly $1 trillion over 10 years. www.nytimes.com/2026/04/04/b...

A tweet by DHS with a painting of Jesus on the crucifix 

Luke 23:46
On this solemn day, we reflect on the ultimate sacrifice our Savior made for all humanity.
Trust in God's plan.

The verse is printed over the painting, with a cross icon directly over Jesus’s crotch: 

“FATHER INTO THY
HANDS I COMMEND MY SPIRIT”

NASA’s moon mission day one—a toilet mishap and spacecraft maneuvers The first day of the Artemis II mission saw the crew enter Earth orbit and prepare for their journey around the moon

Lots happened overnight for Artemis II—tests of Orion's maneuverability, minor orbital adjustments to prep for a translunar injection burn later today, and even a bit of troubleshooting with the spacecraft's fancy toilet! @sciam.bsky.social has the details

NASA’s Artemis II launches on first crewed moon mission of the 21st century A daring 10-day voyage will take four astronauts on a loop around the moon and set the stage for future forays to the lunar surface

Now on @sciam.bsky.social: Artemis II is truly underway, with main engine cutoff & other launch milestones in the rearview. Soon, our planet will be in the rearview too, as tomorrow the mission embarks on its voyage to the moon. By @nadiadrake.bsky.social

NASA is now starting terminal countdown for Artemis II launch. This is really happening, folks. We are imminently sending astronauts beyond low-Earth orbit, bound for the moon, for the first time in nearly 54 years. A new era of human spaceflight starts *now*. Tune in and follow along!

Headline: NASA astronauts are counting down to the Artemis II moon launch. Displayed over a photo of four people in bright orange space suits.

At bottom, an image of the Artemis II rocket on the launch pad. Text above it reads:
NASA is targeting April 1 to launch Artemis II, sending four astronauts on a mission around the moon that will help shape its future lunar exploration plans.
If it proceeds, the flight would mark the first time humans travel beyond Earth orbit in more than 50 years, since Apollo 17 in 1972.
The mission will use the Space Launch System rocket and Orion crew capsule, though both have faced multiple delays this year due to issues discovered during testing.

Portraits of each of the Artemis II astronauts: NASA's Reid Wiseman, commander; NASA's Victor Glover, pilot; NASA's Christina Koch, mission specialist; and Canada's Jeremy Hansen, mission specialist.
Text above reads: Artemis II will carry three NASA astronauts and one Canadian astronaut on a 10-day mission that could take them farther into space than any humans have gone before.

At top, a diagram showing the Artemis II mission's flight path. Text reads:
The mission will test critical systems, conduct medical and scientific experiments, and enable observation of the moon's far side.
While satellites and some Apollo missions have captured parts of the far side, the crew may see areas of the lunar surface never before viewed by humans.
Artemis II will also help validate technology for future missions, including Artemis III and a planned moon landing during Artemis IV, and support NASA's long-term goal of establishing a sustained human presence on the moon.

The widespread belief that kids today are uniquely unwell is weird, because as Melinda Wenner Moyer shows, they're less narcissistic & more empathetic & tolerant than previous gens; IQs are up; drug use, violence, teen pregnancies are down. The list goes on
