Landing site positioning and descent trajectory reconstruction of Tianwen-1 on Mars

Mars Science Laboratory Entry, Descent and Landing Trajectory Reconstruction Uncertainty Assessment

On August 5, 2012 the Mars Science Laboratory (MSL) entry vehicle successfully entered and landed on the Mars surface. During Entry Descent and Landing (EDL), the Curiosity rover was carried by the entry vehicle and carefully lowered to the ground near Gale crater. After completion of the EDL mission, trajectory reconstruction analyses were performed in order to assess the performance of the en...

Mars Smart Lander Simulations for Entry, Descent, and Landing

Two primary simulations have been developed and are being updated for the Mars Smart Lander Entry, Descent, and Landing (EDL). The high fidelity engineering end-to-end EDL simulation that is based on NASA Langley’s Program to Optimize Simulated Trajectories (POST) and the end-to-end real-time, hardware-in-the-loop simulation test bed, which is based on NASA JPL’s Dynamics Simulator for Entry, D...

Minimum-Fuel Powered Descent for Mars Pinpoint Landing

Motivated by the requirement for pinpoint landing in futureMarsmissions, we consider the problemofminimumfuel powered terminal descent to a prescribed landing site. The first-order necessary conditions are derived and interpreted for a point-mass model with throttle and thrust angle control and for rigid-bodymodel with throttle and angular velocity control, clarifying the characteristics of the...
