受通信能力低、能源不足等限制,祝融号火星车有效载荷科学探测需提高探测效率,以有限资源获取尽可能多的有效探测数据。祝融号火星车的巡视探测科学任务着眼于火星局部地区,包括火星车行驶时载荷探测和火星车停止时定点就位载荷探测两个主要工况。统筹考虑祝融号火星车移动能力、通信能力、能源能力、热控能力等约束,合理划分工程活动和科学探测活动可用的资源,协调使用火星车的桅杆和移动系统,优化组合各载荷工作模式,设计了高效载荷探测模式。该探测模式与基于工作模式表的自主探测控制方式相结合,解决了资源受限情况下的多载荷协同探测难题。祝融号火星车有效载荷系统圆满完成了预期探测任务,设计的科学探测模式全部得到在轨验证。结果表明这些模式设计合理有效,满足安全、自主、高效开展科学探测的需求。 相似文献

Chang'E-1 and Chang'E-2 of China's Lunar Exploration Program (CLEP) have successfully achieved their mission. At the present time, only Chang'E-3 is still in operation, which was successfully launched on December 2, 2013. Chang'E-3 probe is the third robotic lunar mission of CLEP, which consists of a lander and a rover, with eight payloads on board the spacecraft. Up to December 21, 2015, more than 2.86TB raw data were received from these instruments onboard Chang'E-3 probe. A series of research results have been achieved. This paper gives a detailed introduction to the new scientific results obtained from Chang'E-3 missions. 相似文献

Chang'E-1 lunar Orbiter was launched by Long March 3A rocket from Xichang Satel-lite Launch Center at 18:05BT(Beijing Time) Oct.24,2007.It is the first step of its ambitious three-stage moon program,a new milestone in the Chinese space exploration history.The primary science objectives of Chang'E-1 lunar orbiter are to obtain three-Dimension(3D) stereo images of the lunar surface,to analyze the distribution and abundance of elements on the surface,to investigate the thickness of lunar soil,evaluate helium-3 resources and other characteristics,and to detect the space environment around the moon.To achieve the above four mission objectives,eight sets of scientific instruments are chosen as the payloads of the lunar orbiter,including a CCD stereo camera(CCD),a Sagnac-based interferometer spectrometer(ⅡM),a Laser Altimeter(LAM),a Microwave Radiometer(MRM),a Gamma-Ray Spectrometer(GRS),an X-ray spectrometer(XRS),a High-Energy Particle Detector(HPD),and two Solar Wind Ion Detectors(SWID).The detected data of the payloads show that all payloads work well.This paper introduces the status of payloads in the first phase and preliminary scientific results. 相似文献

China's Chang'E-4 probe successfully landed on 3 January 2019 in Von Kármán crater within the South Pole-Aitken (SPA) basin on the lunar far side. Based on the data acquired by the scientific payloads onboard the lander and the rover, the researchers obtained the related information such as the geologic and tectonic setting of the landing area, compositional characteristics of the landing surface materials, dielectric permittivity and density of the lunar soil. The experiments confirmed the existence of materials dominated by olivine and low-calcium pyroxene in the SPA basin on the lunar far side, which preliminary revealed the geological evolution history of the SPA basin and even that of the early time lunar crust, as well as the tectonic setting and formation mechanism of the materials in the lunar interior. The researchers also inves-tigated the particle radiation, Linear Energy Transaction (LET) spectrum, and so forth on the lunar surface. The low-frequency radio observations were carried out on the lunar far side for the first time as well. This article summarizes the latest scientific results in the past years, focusing on the Chang'E-4 mission.

Chang'E-1, the first lunar mission in China, was successfully launched on October 24,2007, which opened the prelude of China's Lunar Exploration Program. Later on, the Chang'E-2 and Chang'E-3 satellites were successfully launched in 2010 and 2013, respectively. In order to achieve the science objectives, various payloads boarded the spacecraft. The scientific data from these instruments were received by Beijing and Kunming ground stations simultaneously. Up to now, about 5.628 Terabytes of raw data were received totally. A series of research results has been achieved. This paper presents a brief introduction to the main scientific results and latest progress from Chang'E-3 mission. 相似文献
