space flight causes many changes in

human health understanding these changes

00:00:13,430 --> 00:00:11,440
is important when planning for human

exploration beyond low earth orbit and

00:00:22,390 --> 00:00:20,870
there are components of rodent biology

that are directly related to human

almost every gene found in humans so far

has been found in a closely related form

00:00:53,750 --> 00:00:46,630
we can use the rodent research model for

00:00:57,350 --> 00:00:55,430
because changes occur more quickly in

13
00:00:58,510 --> 00:00:57,360
rodents we can study these changes more

differences between humans and rodents

20
00:01:39,350 --> 00:01:36,079
to gain insight into changes brought

about by spaceflight

rodent space flight studies have already

00:01:58,290 --> 00:01:54,640
contributed to pharmaceutical
