The long-awaited launch of NASA's Artemis II mission dominated science news this week, with the excitement peaking Wednesday (April 1) as the space agency's first crewed mission to the moon in over 50 years blasted off from Cape Canaveral, Florida.
Millions tuned in around the world as the towering Space Launch System rocket and Orion capsule rose off the launchpad at Kennedy Space Center at 6:35 p.m. EDT. Live Science covered the launch live, with reporters following the action both remotely and directly from Florida's Space Coast.
The liftoff mostly went off without a hitch, though the launch team had to resolve one unusual range issue before takeoff. The four Artemis II crewmembers are now well into their 10-day journey around the moon, during which they'll run tests aimed at building NASA's capacity to execute its planned lunar surface missions. Live Science will be covering highlights from the mission, including its expected reentry on April 10, so stay tuned for updates.
In type 1 diabetes, the immune system has learned to attack islet cells in the pancreas and relentlessly destroy them. New research has found a way to eliminate this autoimmune attack without completely erasing the immune system.

In type 1 diabetes, the immune system attacks cells that make insulin, leaving the body with too little of the blood-sugar-controlling hormone. Those insulin-making cells can be replaced, but the procedure typically requires patients to undergo lifelong immune suppression, which comes with its own serious health complications.
Now, in a new study, scientists explored a way to transplant insulin-making cells without the need for immunosuppression. So far, the approach has shown promise in lab mice, though much more work is needed to show it works in humans. But in theory, it could pave the way to a cure, experts told Live Science.

A very long solar filament that had been snaking around the sun erupted with a flourish on Dec. 6, 2010.

Life on Earth literally revolves around the sun's light and energy — but what would happen if our companion star suddenly winked out of existence? Live Science contributor Jesse Steinmetz tackles the question of what a suddenly sunless Earth might be like and which organisms might survive in such a cold, dark place.
New research revealed China's actions to clean up its air pollution impacted other areas of the globe.

China launched an effort to clean up its air in 2013, and in the decade or so since, the country has lowered its sulfate aerosol emissions by about 75%. A new study took a look at the global impact of that impressive feat, showing that the loss of smog over China likely spared the Arctic from sea-ice-damaging cyclones. The smog previously detoured storms across the North Pacific, funneling them into the Arctic, where they would destroy ice in the Bering Sea.
However, it's not all good news: Aerosols cool the planet, so their disappearance can ultimately unmask greenhouse-gas-driven warming that was once offset by pollution's cooling effect. In short, it's a complicated picture that will take more research to fully understand.

NASA's Artemis II mission will not only help the space agency prepare for its future trips to the lunar surface but also offer a unique opportunity to study the impacts of deep space on human health. With the sun having recently passed its peak in activity, called solar maximum, could the four-person crew face even more risk from radiation than they would otherwise?
To unpack the effects of space weather on the human body, Live Science trending news writer Patrick Pester spoke with Patricia Reiff, a professor of physics and astronomy at Rice University in Houston. Counterintuitively, she explained that solar maximum may be a better time for the Artemis II mission than you might assume.
Something for the weekend
If you're looking for something a little longer to read over the weekend, here are some of the best analyses, crosswords and opinion pieces published this week.
The main sensory nerve of the clitoris, the dorsal nerve, is labeled in yellow. Veins and other tissues are shown in different colors.

Scientists recently unveiled the first 3D map of the clitoral nerves, which renders the tissues at micron-scale resolution. The effort involved CT scans stitched together from X-rays that used an extremely bright light source, called a synchrotron. Prior to this research, other scientists had studied the general structure of the clitoris using MRI and tallied up the 10,000 or so nerves in the organ. But the 3D map provides new insights into the nerves' structures that could be incredibly useful for surgeons to reference.
Mount Arkanu is a massif made up of concentric rocky rings topped with a large hat-like formation. The entire structure is over 15 miles wide.

A photo snapped in 2025 by an astronaut shows concentric mountain ridges in the Libyan desert. Known as Mount Arkanu (sometimes spelled Arkenu), the colossal structure was once thought to be an ancient impact crater. But recent research suggests it actually formed from magma repeatedly rising toward the surface and intruding into the surrounding rock. Mount Arkanu bears ancient artworks depicting human figures, along with cattle and other tethered animals, such as giraffes.

NASA's Artemis II crew launches to the moon
NASA's Artemis II Crew Launches To The Moon (Official Broadcast) - YouTube
If you couldn't watch the Artemis II launch live Wednesday, don't fret! NASA's coverage of the event can be found on the agency's YouTube channel. (And for detailed explanations of the science you're seeing, check out Live Science's live coverage.)
Besides witnessing the epic moment of liftoff, you can learn about NASA astronaut's wide array of prelaunch rituals, the menus the crew will tuck into on their venture, and the mission's official mascot, Rise, designed by 8-year-old Lucas Ye of California. The coverage also digs into all the details of how the Artemis II mission will proceed now that the astronauts have exited Earth's atmosphere.
