长五火箭最后一个贮箱完成下架​

近日，用于首飞的长征五号运载火箭二级氢箱下架，标志着该火箭所有5米级贮箱已完成生产。长五火箭向着成功首飞又迈进了一大步。

自今年年初起，长五火箭的一级氢箱、一级氧箱陆续完成生产。此次下架的二级氢箱是长五火箭上最后一个5米直径贮箱。该贮箱采用搅拌摩擦焊、悬空焊等先进的自动焊接技术，改进焊接工装，焊接质量比初样阶段得到大幅提升。（吴思）

Translation:

Recently with the roll out of the second stage hydrogen tank for the Long March 5 rocket intended for maiden flight, marks the end of the production stage of the five meter diameter tank, and a major step forward.

Since beginning of this year, LM-5 rocket first stage hydrogen and oxygen tank production has been continuously carried out. The roll out of this second stage hydrogen tank is the last of the 5 meter tanks. Production of the tanks utilize friction stir welding, suspended welding and other advanced automatic welding technology, with improved welding tooling, welding quality has improved substantially over the initial prototype stage.

DAMPE is a powerful space telescope for high energy gamma-ray, electron and cosmic rays detection. It consists of a double layer of plastic scintillator strips detector (PSD) that serves as anti-coincidence detetor, followed by silicon-tungsten tracker-converter (STK), which is made of 6 tracking double layers; each consists of two layers of single-sided silicon strip detectors measuring the two orthogonal views perpendicular to the pointing direction of the apparatus. Three layers of Tungsten plates with thickness of 1mm, 2mm and 2mm are inserted in front of tracking layer 2, 3 and 4 for photon conversion. The STK is followed by an imaging calorimeter of about 31 radiation lengths thickness, made up of 14 layers of BGO bars in a hodoscopic arrangement. A layer of neutron detectors is added to the bottom of the calorimeter. The total thickness of the BGO calorimeter and the STK correspond to about 33 radiation lengths, making it the deepest calorimeter ever used in space.

The main scientific objective of DAMPE is to measure electrons and photons with much higher energy resolution and energy reach than achievable with existing space experiments in order to identify possible Dark Matter signatures. It has also great potential in advancing the understanding of the origin and propagation mechanism of high energy cosmic rays, as well as in new discoveries in high energy gamma astronomy.
DAMPE will have unprecedented sensitivity and energy reach for electrons, photons and cosmic rays (proton and heavy ions). For electrons and photons, the detection range is 5 GeV – 10 TeV, with an energy resolution of about 1% at 800 GeV. For cosmic rays, the detection range is 100 GeV – 100 TeV, with an energy resolution better than 40% at 800 GeV. The geometrical factor is about 0.3 m 2 sr for electrons and photons, and about 0.2 m2 sr for cosmic rays. The angular resolution is 0.1° at 100 GeV.

IAU Named Land on Moon After Chinese Mythology
By Shen Chen (People's Daily Online) 11:11, November 13, 2015

International Astronomical Union (IAU) named 4000 square meters' land on moon as "Guang Han Gong". The land was circulated by the route China's moon rover "Yutu" had hiked.

In ancient Chinese mythology, "Guang Han Gong" (广寒宫）is the name of the palace on moon, where Chang'e （嫦娥), the Chinese goddess of the Moon, and her pet Jade Rabbit(Yutu, as in “玉兔”） reside.

China's first moon rover Yutu landed on the moon via China's Chang'e-3 lunar probe in 2013. The rover has been operating on the moon for two years, setting the record for the longest stay by a rover on the lunar surface.

Three craters near the "Guang Han Gong" area were also named by IAU as "Zi Wei", "Tai Shi", and "Tai Wei", which are the ancient names of Chinese constellations.
