I am Sara Rengifo. I am a Tribolgy and

3
00:00:13,940 --> 00:00:17,345
Metrology engineer. I have been working

4
00:00:17,380 --> 00:00:21,849
at MSFC for almost 3 years. I was born in

5
00:00:21,884 --> 00:00:24,609
Medellin. I love being a Colombian, I love

6
00:00:24,644 --> 00:00:27,561
my accent. I know so many times people

7
00:00:27,596 --> 00:00:29,929
don't even understand what I am saying

8
00:00:29,964 --> 00:00:32,481
but my accent is something I can not get

9
00:00:32,516 --> 00:00:36,001
rid of. Since I was very little, I always

10
00:00:36,036 --> 00:00:38,569
wanted to be a scientist. I was always

11
00:00:38,604 --> 00:00:41,657
mixing things food and all the jars were

12
00:00:41,692 --> 00:00:45,009
mine. My Mom had to save all the jars for

13
00:00:45,044 --> 00:00:47,625
me. So, when I graduated, I knew I

14
00:00:47,660 --> 00:00:50,257
wanted to be a mechanical engineer.

15
00:00:50,292 --> 00:00:53,096
Tribology is the study of lubrication,

16
00:00:53,131 --> 00:00:56,913
wear and friction. Metrology is

17
00:00:56,948 --> 00:00:59,161
connected to Trobology. So many

18
00:00:59,196 --> 00:01:02,169
times we run tribology testing and then

19
00:01:02,204 --> 00:01:05,369
we take the materials to the metrology

20
00:01:05,404 --> 00:01:07,761
side and we inspect what happened

21
00:01:07,796 --> 00:01:10,537
after the mechanical test. So we measure

22
00:01:10,572 --> 00:01:14,785
wear. We also can measure surface

23
00:01:14,820 --> 00:01:19,129
texture parameters and verify tolerances

24
00:01:19,164 --> 00:01:24,241
and see if maybe our customers have

25
00:01:24,276 --> 00:01:26,785
what they require, what they need.

26
00:01:26,820 --> 00:01:29,200
We have five different labs. These labs

27
00:01:29,235 --> 00:01:31,649
are environmental, particles control,

28
00:01:31,684 --> 00:01:33,649
humidity control and temperature

29
00:01:33,684 --> 00:01:37,553
control. I am always trying to make our

30
00:01:37,588 --> 00:01:40,713
labs better to help the labs to get the

31
00:01:40,748 --> 00:01:43,401
latest technology. I really want my

32
00:01:43,436 --> 00:01:46,616
labs to get the best data for the project

33
00:01:46,651 --> 00:01:49,233
and support them in the best way we

34
00:01:49,268 --> 00:01:51,689
can. Right now we support a variety

35
00:01:51,724 --> 00:01:55,113
of projects. We work a lot with  ECLSS,

36
00:01:55,148 --> 00:01:59,153
Orion, additive manufacturing, Europa

37
00:01:59,188 --> 00:02:03,825
lander, RS-25. Now that we plan to go

38
00:02:03,860 --> 00:02:07,689
to the moon in 2024, I'm working really

39
00:02:07,724 --> 00:02:09,481
hard trying to meet the project

40
00:02:09,516 --> 00:02:11,961
managers and trying to meet the

41
00:02:11,996 --> 00:02:15,097
people that is related to lunar landers.

42
00:02:15,132 --> 00:02:17,297
I want tribolgy and metrology to

43
00:02:17,332 --> 00:02:19,505
support these projects. Right now,

44
00:02:19,540 --> 00:02:22,840
our plan is to run some tribology testing

45
00:02:22,875 --> 00:02:26,441
and see the negative effect of the

46
00:02:26,476 --> 00:02:29,713
regolith on the mechanisims. Being

47
00:02:29,748 --> 00:02:33,233
Colombian to me means a lot because

48
00:02:33,268 --> 00:02:35,273
coming with a different background
