Preparing for Artemis II astronaut safety at the SWPC’s Space Weather Prediction Testbed. We are exercising critical support to protect human spaceflight from solar hazards by active engagement between SWPC forecasters, science and research elements, space launch personnel, key operations support staff, and more from April 29th - May 8th. This is all being done at the SWPC Testbed with scenarios as though events of significance were happening in real time. Learn more by reading the SWPC Testbed Artemis II - Human Space Flight story.
