International efforts in asteroid defense and lunar navigation continue to advance. China’s National Space Administration (CNSA) plans a 2027 launch to test kinetic impact deflection on asteroid 2015 XF261. Led by scientist Li Mingtao, the mission will use an impactor traveling at over 9 km/s—significantly faster than NASA’s 2022 DART mission—to attempt to alter the object's orbit. Regarding lunar operations, NASA is progressing with the CAPSTONE 02 mission, scheduled for 2027. The mission will deploy two 400-kg spacecraft, built by Terran Orbital Systems and Advanced Space, into a near-rectilinear halo orbit. These probes will alternate between “chaser” and “target” roles to validate autonomous navigation, docking, and formation-flying in complex three-body gravitational environments. Advanced Space, acting as prime contractor, is partnering with Utah State University’s Space Dynamics Laboratory (SDL) to provide flight-qualified Iris Radios for communications and precise timekeeping. These systems will support both direct-to-Earth and spacecraft-to-spacecraft crosslinks to demonstrate coordinated autonomy. This technology is essential for the Artemis program’s requirement to coordinate launches between NASA’s Orion, Blue Origin’s lander, and SpaceX’s lander. NASA Administrator Jared Isaacman noted that achieving a late 2028 Moon landing goal relies heavily on SpaceX’s engineering and financial capabilities, stating, “We can’t do it without them.” Preparations for Artemis III, planned for late 2027, remain focused on crew readiness. The four-person crew includes pilot Luca Parmitano, commander Randy Bresnik, and specialists Andre Douglas, Frank Rubio, and Robert Hines. Astronauts and geologists are undergoing underwater training at the Neutral Buoyancy Laboratory to simulate lunar south-pole conditions, including practicing sample collection in low-light environments. Meanwhile, academic interest in lunar orbits grows, with University of Cambridge researchers proposing the CosmoCube satellite to study the early universe from the Moon’s far side.
