• NASA revealed a $20 billion fast-tracked initiative to establish a permanent moon base, with the rocket for astronaut lunar missions launching Wednesday. • The plan accelerates U.S. space exploration goals amid competition, building on Artemis program advancements for sustainable lunar presence. • This development matters for enabling long-term human spaceflight, resource utilization, and preparation for Mars missions.

Follow latest updates, including how to watch the launch, as four astronauts prepare to set off on a 685,000-mile journey with millions watchingA two-hour launch window for Artemis II opens at 6.24pm EST (11.24pm BST) after an almost four-hour fueling process. Nasa’s final weather briefing on Tuesday reported an 80% chance of favorable conditions for launch.Mission managers will be watching closely data from launchpad 39B at the Kennedy Space Center, as well as real-time and forecast weather information. Any last-minute technical issue or weather violation can cause a scrubbed launch attempt, or a delay, right up to T-0 (the moment the countdown clock reaches zero). Continue reading...

The discovery of a medieval Scottish ferry with a roll-on, roll-off feature for carts also provided some much-needed levityThe media ecosystem may have changed since the BBC’s spaghetti harvest report in 1957 or the Guardian’s 1977 travel supplement about the island of San Serriffe, but April fool stories are still with us.Indeed, if you picked up Wednesday’s edition of the Guardian, you may have been taken in by our report that evidence had been found of coffee being consumed in England a couple of centuries before the first known examples, thanks in part to an expert called Macky Arto.

Fully crewed rocket will head to moon from Florida – first time since 1972 that humans will have left lower Earth orbitA little more than an hour before sunset on Florida’s space coast, up to 400,000 people packed on beaches and causeways will look to the heavens on Wednesday to witness a fiery spectacle not seen in almost 54 years: a fully crewed Nasa rocket heading back to the moon.The launch of Artemis II, scheduled for 6.24pm ET if weather and any late technical gremlins grant their consent, marks the first time since the Apollo 17 mission of December 1972 that humans will have left lower Earth orbit.

• NASA's Artemis II mission, the first crewed flight test of the Space Launch System (SLS) rocket and Orion spacecraft, has cleared its final hurdle and remains on track for launch no earlier than April 1, 2026. • The mission will send four astronauts—Reid Wiseman, Victor Glover, Jeremy Hansen, and Christina Koch—on a 10-day orbital test around the Moon, validating systems for future lunar landings. • This milestone follows rigorous technical reviews, ensuring crew safety and vehicle performance after lessons from uncrewed Artemis I in 2022.

• NASA announced revisions to its lunar exploration plans, delaying the first crewed Artemis IV landing to early 2028 while pausing the Gateway lunar station to prioritize a surface base. • The International Space Station's retirement is postponed to the mid-2030s, with plans to add detachable modules for a future standalone station, facing pushback from private space firms. • NASA will launch Space Reactor-1 Freedom, a nuclear engine demonstration to Mars, scheduled for December 2028 to test advanced propulsion.

• NASA announced nuclear rocket development as part of this week's major science news, signaling advancement in propulsion technology for future space missions. • The announcement was featured in Live Science's weekly roundup of the latest scientific developments, alongside research on space reproduction challenges and insights into cannabis effects on appetite. • Nuclear propulsion systems represent a significant technological leap that could enable faster deep-space exploration and reduce mission duration for long-distance space travel.
