天問三號載荷

轨道器将搭载3台合作载荷，分别为：国际空间研究委员会探索工作组牵头研制的火星PEX光谱仪，用于开展火星生命痕迹探寻及表面矿物成分探测；澳门科技大学牵头研制的火星分子离子成分分析仪，用于开展火星大气逃逸过程探测；

香港中文大学牵头研制的激光外差光谱仪，用于开展火星大气水同位素廓线分布及火星风场探测。

服务器将搭载香港大学牵头研制的火星地物高光谱成像仪，用于开展生命痕迹、含水矿物及资源普查等探测。

着陆器将搭载意大利国家核物理研究院-弗拉斯卡蒂国家实验室牵头研制的激光角反射器阵列，用于在火星表面布设精确基准点。

据悉，中国行星探测工程天问三号任务，计划于2028年前后实施发射，2031年前后携带火星样品返回地球。

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

14 Oct 2020, being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station. The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station. previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
