My name is Florence Tan, I'm the SAM Electrical Lead Engineer, I work at Goddard Space Flight Center.

00:00:10.550 --> 00:00:16.680
SAM stands for Sample Analysis at Mars. It is an organic chemistry lab on the Curiosity rover,

4
00:00:16.700 --> 00:00:21.150
it is the most well-equipped chemistry lab that we've sent to Mars to date.

5
00:00:21.170 --> 00:00:30.260
Curiosity landed on Mars on August 5, 2012. It was born on Mars that day, and so we consider that day as its birthday.

6
00:00:30.280 --> 00:00:36.130
We're here at the test bed lab where SAM was built. It is an identical unit to the unit on Mars,

7
00:00:36.150 --> 00:00:41.500
and we use this unit to test our experiments before it is transmitted to Mars.

8
00:00:41.520 --> 00:00:47.980
SAM will be running some great science experiments on Mars, we will be analyzing some soil samples.

9
00:00:48.000 --> 00:00:53.430
To make the soil samples go down, we have to program it to vibrate at various frequencies.

10
00:00:53.450 --> 00:00:58.430
When we're introducing a sample into SAM, it will go through a resonance and it will sound like this.

00:00:58.450 --> 00:01:08.010
[ electronic tone ]

12
00:01:08.030 --> 00:01:13.730
To commemorate SAM's birthday and Curiosity's birthday on Mars, we decided to play a little song.

13
00:01:13.750 --> 00:01:19.930
If there's anyone listening on Mars on this special occasion, you will hear this.

14
00:01:19.950 --> 00:01:42.430
[ Happy Birthday to You ]

15
00:01:42.450 --> 00:01:50.060
It's really neat, and it's exciting! This is a first for NASA and for the world, and music brings us all together so this is fun!

16
00:01:50.080 --> 00:01:54.280
It's been a great year on Mars and I cannot wait to get to Mount Sharp next year.

17
00:01:54.300 --> 00:01:59.680
We've discovered so many new things, and there's still lots more discoveries to come.
