phase
Flight simulation test for operation on lunar surface
Flight simulation test for hibernation and awakening
Flight simulation test for all mission phases
Failure mode test
Basic status test
Self-test of lunar lander
simulation test was to verify flight events in all flight phases according to the flight
procedure, and to verify the reasonableness of flight procedure design. The purpose
of basic status test was to determine whether the lunar lander was in good status by
subsystem self-test.
On the basis of heritage of electrical testing methodology for previous deep space
probes, in order to verify new technology and new instrument function of the lunar
lander, new test methodology was designed for new tests. For example, there are
examples including flight simulation test for all mission phases, flight simulation test
for powered descent phase, communication function test between the lunar lander
and the lunar rover, function test for hibernation and awakening as follows.
