I’m Van Feng, I’m Manager of The International
Space Station Transportation Integration Office.

The International Space Station is a perfect
test bed for testing technologies before we

3
00:00:17,699 --> 00:00:21,929
go on to Mars. The Martian trip is several
years including a nine-month journey to and

4
00:00:21,929 --> 00:00:25,669
from Mars. The Space Station is basically
in our own backyard, only two-hundred and

5
00:00:25,669 --> 00:00:30,599
fifty miles up. We can test things in micro-gravity,
perfect them before we go off onto the much

6
00:00:30,599 --> 00:00:34,640
longer journey onto Mars.
Similarly, we’re testing a human system

7
00:00:34,640 --> 00:00:38,929
to be able to identify the things that degrade
when crew members are in micro-gravity or

8
00:00:38,929 --> 00:00:42,370
reduced gravity for long periods of time.
As well as developing counter measures to

00:00:42,370 --> 00:00:45,920
ensure that on our long journeys once they
arrive at the Martian surface, they are going
