NASA presented an optimistic progress report on Artemis III, its crewed lunar mission, but outside experts warn the ambitious timeline faces real obstacles. The agency has made engineering strides on the Space Launch System rocket and Orion spacecraft, yet significant hurdles remain, from heat shield testing to life-support systems. Officials project a landing in the late 2020s, though some analysts question whether that date can hold given past delays and budget pressures. The mission hinges on sustained political backing and funding, neither guaranteed as administrations change. Success would mark the first human lunar landing since 1972.
