Deployable boom for Mars Orbiter Magnetometer onboard Tianwen-1

JUSTC, 2022
A more than 3 m-long deployable boom is an essential component of the Mars Orbiter Magnetometer (MOMAG) onboard the orbiter of Tianwen-1. The boom was developed to place fluxgate magnetometer (FGM) sensors away from the satellite to reduce the influence of the satellite magnetic field.

Prossima al traguardo, Tianwen-1 fotografa Marte

2021
La sonda spaziale cinese Tianwen-1 è in rotta verso Marte dallo scorso 23 luglio 2020 e sta per giungere alla meta. Nel frattempo ha già operato varie correzioni orbitali e comincia a scattare fotografie a distanza ravvicinata, come questa in bianco e nero, realizzata a 2.2 milioni di km di distanza dalla superficie marziana.

The Development of Emergency Communication Device for Tianwen-1 Probe

Guidance, Navigation and Control, 2022
Mars is one of the most valuable planets for space exploration. After entering the entry descent and landing (EDL) phase, the spacecraft would carry out a series of procedural deceleration operations and achieve soft landing on the surface of Mars. In the process of EDL, the landing platform would encounter a series of irreversible incidents within ...

Cosa faranno Hope, Tianwen-1 e Perseverance

2021
Ora che sono giunti tutt’e tre a destinazione, gli “esploratori marziani“ partiti l’estate scorsa possono iniziare a lavorare. Facciamo dunque il punto sugli obiettivi scientifici delle missioni degli Emirati Arabi, della Cina e degli Stati Uniti, e vediamo quali possibilità lasceranno aperte per la futura esplorazione del programma europeo ...

In-flight calibration of the magnetometer on the Mars orbiter of Tianwen-1

Science China Technological Sciences, 2023
Mars orbiter magnetometer (MOMAG) is one of seven science payloads onboard Tianwen-1’s orbiter. Unlike most of the satellites, Tianwen-1’s orbiter is not magnetically cleaned, and the boom where placed the magnetometer’s sensors is not long enough. These

Dense Rocks With Smooth Surfaces in Martian Regolith Revealed by Polarimetric Analysis of GPR Data: A Case at Tianwen‐1 Landing Site, Mars

Journal of Geophysical Research: Planets
This article reports the results of full‐polarimetric Mars Rover Penetrating Radar (RoPeR) data acquired by the Zhurong rover of China's Tianwen‐1 (TW‐1) mission. A modified Freeman decomposition method is applied to the analysis of RoPeR data.
