Mars Gravity Field Determination Using Tianwen-1 Orbiter Tracking Data
The Martian gravity field is a key data set for studying the internal structure of Mars. For this purpose, we processed all the two-way Doppler tracking data of the Tianwen-1 orbiter from 2021 June to 2024 October and determined a new degree and order 80

Thin regolith layer anticipated on the surface of the Tianwen-2 target asteroid (469219) Kamo‘oalewa
Astronomy & AstrophysicsContext. Near-Earth asteroid (469219) Kamo‘oalewa is the first target of the ongoing Tianwen-2 sample-return mission. Ground-based observations measured its rotation period at only about 28 minutes, while the low thermal inertia value (Γ = 150 or 181 J m−

ElectronicsSince Mars is far away from Earth, the propagation delay between Mars and Earth is very large. To ensure the effective use of the link transmission bandwidth, China’s first Mars exploration mission has put forward a demand for data compression for all scientific payloads. The on-board mature algorithms for data compression are mainly focused on optical
