Developing a prototype ALHAT Human System Interface for landing

NASA's Autonomous Landing and Hazard Avoidance Technology (ALHAT) project is developing technologies for safe landing anytime/anywhere on planetary surfaces. Minimizing time, thus minimizing fuel consumption, is critical during landing, so ALHAT displays must convey information efficiently to operators. The ALHAT Human System Interface (HSI) team developed prototype displays, explored methods of providing situation awareness, and modeled the cognitive task and information requirement for landing site selection. Input from NASA astronauts and mission controllers was solicited to refine ALHAT display concepts in a series of evaluations. This paper discusses the evolution of ALHAT displays and future plans for ALHAT HSI.
