An Efficient High-Resolution Global-Local Network to Detect Lunar Features for Space Energy Discovery
Liu, Lei; Jia, Yutong; Peng, Siqing +2 more
Lunar craters and rilles are significant topographic features on the lunar surface that will play an essential role in future research on space energy resources and geological evolution. However, previous studies have shown low efficiency in detecting lunar impact craters and poor accuracy in detecting lunar rilles. There is no complete automated …
Subpixel-Scale Topography Retrieval of Mars Using Single-Image DTM Estimation and Super-Resolution Restoration
Tao, Yu; Michael, Greg; Muller, Jan-Peter +5 more
We propose using coupled deep learning based super-resolution restoration (SRR) and single-image digital terrain model (DTM) estimation (SDE) methods to produce subpixel-scale topography from single-view ESA Trace Gas Orbiter Colour and Stereo Surface Imaging System (CaSSIS) and NASA Mars Reconnaissance Orbiter High Resolution Imaging Science Expe…
A New Method for Retrieving Electron Density Profiles from the MARSIS Ionograms
Le, Huijun; Liu, Libo; Chen, Yiding +7 more
The Martian ionosphere was actively detected by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) aboard the Mars Express. The detected echo signal of the MARSIS at an epoch is presented as a function of frequency and time delay to form an ionogram. Some MARSIS ionograms have been processed to obtain the electron density profiles…
Development of Chaos Terrain as Subaqueous Slide Blocks in Galilaei Crater, Mars
Nizam, Nabila; Divola, Claire; Day, Mackenzie +2 more
Chaos terrain, expressed as enigmatic blocky landscapes on Mars, has poorly understood origins. Several hypotheses have been put forward to explain chaos terrain formation, but none fully account for the morphologies observed in Galilaei crater, the focus of this study. Previously inferred to be a paleolake, Galilaei crater hosts chaos terrain com…
Cold Atom Interferometry for Enhancing the Radio Science Gravity Experiment: A Phobos Case Study
Dirkx, Dominic; Plumaris, Michael; Siemes, Christian +1 more
Interplanetary missions have typically relied on Radio Science (RS) to recover gravity fields by detecting their signatures on the spacecraft trajectory. The weak gravitational fields of small bodies, coupled with the prominent influence of confounding accelerations, hinder the efficacy of this method. Meanwhile, quantum sensors based on Cold Atom…
