Braking and attitude control of lunar lander in active descent stage
Open Astronomy, 2023 China officially launched the lunar exploration project, named “Chang’e Project,” in 2004. Then, in 2013, Chang’e-3 completed the soft landing on the lunar surface, starting a series of studies on the soft landing of spacecraft.

Autonomous Drone Landing: Marked Landing Pads and Solidified Lava Flows [PDF]
arXiv, 2023 Landing is the most challenging and risky aspect of multirotor drone flight, and only simple landing methods exist for autonomous drones. We explore methods for autonomous drone landing in two scenarios. In the first scenario, we examine methods for landing on known landing pads using fiducial markers and a gimbal-mounted monocular camera.

Mars Exploration Using Sailplanes
Aerospace, 2022 We present the preliminary design of sailplanes, used for Mars exploration. The sailplanes mitigate the weight and energy storage limitations traditionally associated with powered flight by instead exploiting atmospheric wind gradients for dynamic ...

Color Properties at the Mars InSight Landing Site [PDF]
Earth and Space Science, 2021 AbstractThe color properties observed at the InSight landing site by the lander cameras are spectral mixtures of two source materials: gray‐black rocky material with chromaticity values of x = 0.32, y = 0.32 (standard deviations of σx = 0.02 and σy = 0.03) and yellowish‐brown dust with chromaticity values of x = 0.42, y = 0.36 (standard deviations of ...

Location and Setting of the Mars InSight Lander, Instruments, and Landing Site
Earth and Space Science, 2020 Knowing precisely where a spacecraft lands on Mars is important for understanding the regional and local context, setting, and the offset between the inertial and cartographic frames.
