Weather and technical difficulties have led NASA and its partner, Katalyst, to delay an unprecedented mission aimed at repositioning an aging U.S. satellite using a robotic spacecraft. This mission, initially set to advance orbital technology key to U.S.-China space competition, was meant to tow the Neil Gehrels Swift Observatory to a safer orbit.The innovative mission, planned under a sharp nine-month schedule, faced logistical setbacks due to weather and launch vehicle issues. The LINK spacecraft, intended to rescue the satellite, remains grounded as authorities address these challenges, postponing what could be a vital demonstration of satellite maintenance capabilities.Katalyst's spacecraft, designed to…
