What Does HA Stand For?

HA stands for Apogee Altitude

HA, or Apogee Altitude, refers to the highest point reached by an object in a ballistic trajectory or orbit during its ascent. This measurement is crucial in fields such as aerospace engineering and space exploration, as it determines the peak height of a spacecraft or missile relative to the Earth's surface. Understanding apogee altitude is essential for trajectory optimization, mission planning, and ensuring successful operations in both atmospheric and extraterrestrial environments.
