See below

Explanation:

As mass being independent of 'g' is same on earth and moon.

Talking about weight,
By observing a very basic equation of weight :-
#W = mg#,
we can clearly see that weight is nothing but,
mass of object #* g#

So, this implies that weight of an astronaut is different on earth than that on moon.

Rather, it is found that the value of #'g'# is #(1/6)^(th)# times on moon than that on earth.
#i.e.,# #g_"e" = 1/6 * g_"m"#

So, mass of the astronaut is same but weight is weight becomes #(1/6)^(th)# on moon
