NASA has announced a significant shift in its lunar exploration strategy, cancelling plans for a lunar orbit space station known as Gateway. Instead, the agency will utilize the station's components to construct a $20bn base on the moon's surface over the next seven years.The decision was made by NASA's new chief, Jared Isaacman, who was sworn in at the agency in December. Isaacman outlined the changes to the agency's flagship moon program, Artemis, at an event at NASA's Washington headquarters."It should not really surprise anyone that we are pausing Gateway in its current form and focusing on infrastructure that supports sustained operations on the lunar surface," Isaacman told delegates at the event.The Lunar Gateway station, largely already built with contractors Northrop Grumman and Lanteris Space Systems, owned by Intuitive Machines, was meant to be a space station parked in a lunar orbit. Repurposing the craft for a lunar surface base is not simple, but Isaacman emphasized that the agency can repurpose equipment and international partner commitments to support surface and other program objectives.The changes imposed by Isaacman on the flagship US moon program in recent weeks are reshaping billions of dollars' worth of contracts under the Artemis effort, sending companies scrambling to accommodate the extra urgency as China makes progress toward its own 2030 moon landing.

NASA has initiated the process of returning its massive Space Launch System (SLS) rocket and Orion spacecraft to the launch pad at Kennedy Space Center in Florida. This move comes after completing necessary repairs, setting the stage for a potential launch on April 1.The operation, which can take up to 12 hours, began at 8pm local time. The rocket and spacecraft will be moved 4 miles (6.5km) to launch pad 39B. If all tests are satisfactory, the mission will proceed with a crew of three US astronauts and one Canadian set to fly around the moon.This mission, expected to last about 10 days, marks a significant step towards achieving the goal of returning humans to the lunar surface. The Artemis 2 mission had faced several delays, including issues with helium flow and a liquid hydrogen leak during a previous wet dress rehearsal.The Artemis 2 astronaut crew entered quarantine in Houston as they prepare for liftoff. With the April 1 launch window approaching, NASA remains hopeful that this mission will successfully launch in early April, paving the way for future lunar exploration.
