One station observation system for Mars exploration

    Since entering the 21st century, with the progress and development of science and technology. Human exploration of the world is not limited to the earth. Remarkable achievements have also been made in the exploration and understanding of the planet. In the last century, the US completed the exploration of the internal structure of the moon by using seismological methods through the Apollo program. The successful launch of insight in 2018 marked the birth of Marsquake, and realized the preliminary exploration of the internal structure of Mars. Due to the limitation of aerospace capability, the scientific research equipment we can carry is limited. The NASA spent hundreds of millions of dollars to deploy a seismograph on Mars. However, the deployment of a single seismograph is usually difficult to accurately measure the internal structure of Mars. Because the imaging method based on the internal vibration signal of Mars requires the use of a single seismograph constraining the source information and the internal structure of Mars at the same time, Which will increase the risk of inversion multiplicity.

    The main function of placing seismometers on the planet is to monitor the internal activity law of the planet. However, if we can obtain more reliable planetary exploration data without increasing the detection cost by designing a reasonable observation system, it will play an important role in the future exploration of the internal structure of the planet.

    Thus, a single station observation system is designed, which lays a foundation for seismic imaging to obtain more controllable and reliable data through the combination of single station and moving source(Rover). In this way, we can obtain two-dimensional and three-dimensional planetary seismic profiles in the future.
