00:05 In the space, the environment is quite different.
00:09 We have no air and the heat removal is much more difficult.
00:14 And we have reproduced such condition on Earth by this machine.
00:19 This chamber is a thermal vacuum chamber.
00:23 It means that inside we can generate the space-like environment.
00:28 There are several tests which are important for our data processing units.
00:33 We are preparing the functional testing.
00:35 It means just turning on and turning off.
00:38 But in sometimes demanding temperature condition.
00:43 For example, minus 40 and plus 65 and even higher or lower temperatures.
00:48 The second tests which we are performing are thermal cycling.
00:52 It means we are driving our devices from minus 40 to 65 in really high speed.
00:59 And then we are repeating such activities several times.
01:03 Because on the low Earth orbit where the satellite is cycling around the Earth,
01:09 the temperature change is really rapid.
01:12 And it's important to represent such condition, changing condition on the ground.
