16 Scientific Instrument Technology of Lunar Lander
Table 16.2 (continued)
Engineering environment
Requirements
Measurement parameter or
data
Mechanical properties of
luna soil.
To study bearing capacity and
shearing strength of lunar soil
To study stress status at different
depth
To study hardness, strength,
friction of lunar soil
To optimize locomotion design of
future lunar rover
To optimize structural and
mechanism design of future
lander with landing impact
feature
bearing capacity, shearing
strength, stress at different
depth
Electrical property of
shallow lunar soil
To study permittivity of shallow
lunar soil
To study dielectric loss tangent of
shallow lunar soil
To optimize telecommunication
system design between probes for
future missions
Complex permittivity
Lunar meteoroid
environment
To study the flux of meteoroid
with time
To study velocity, mass of
meteoroid on lunar surface
To analyze and evaluate potential
effects of meteoroid on the lunar
lander.
Relationship of flux, velocity
and mass of meteoroid
Radiation environment on
lunar surface
To study optimized radiation
protection design for robotic and
manned lunar lander
Equivalent radiation dose with
protection
Long term environment
effect
To study performance change of
specific material in long term
space weathering
Specific test material
Above engineering and environment parameters on lunar surface, would be important basis for design of future robotic and manned lunar exploration missions in
China, which played an important role in sustainable development of China lunar
exploration.
The first priority of Chagn’E-3 lunar lander was successful landing. Then priority
should be given to the very important and lightweight engineering instruments. After
proposal and deliberately analyzing, it was determined that there would be three
monitoring cameras to monitor the status of the lunar rover, and one lunar dust
detector to investigate lunar dust accumulation on lunar surface.
