00:00:00,000 --> 00:00:03,600


2
00:00:03,600 --> 00:00:05,070
One of the things
we've been doing

3
00:00:05,070 --> 00:00:09,720
since we launched is calibrating
all the instruments on JWST,

4
00:00:09,720 --> 00:00:14,160
and that means figuring
out, from what we measure,

5
00:00:14,160 --> 00:00:16,290
you know, how fast is
the light coming in,

6
00:00:16,290 --> 00:00:18,480
to what's really going on.

7
00:00:18,480 --> 00:00:21,660
How bright is that star,
that galaxy way out there?

8
00:00:21,660 --> 00:00:24,750
The Mid-Infrared instrument
for Webb, the MIRI instrument,

9
00:00:24,750 --> 00:00:27,090
it's actually performing
amazingly well.

10
00:00:27,090 --> 00:00:30,120
It's surpassing expectations,
and really when you compare

11
00:00:30,120 --> 00:00:32,340
what we are seeing and the
quality of the data with

12
00:00:32,340 --> 00:00:34,110
previous missions, it's --

13
00:00:34,110 --> 00:00:35,100
it's mind blowing.

14
00:00:35,100 --> 00:00:37,500
This morning there was a
lot about the instruments,

15
00:00:37,500 --> 00:00:39,480
and so, for me, one of
the things I work on

16
00:00:39,480 --> 00:00:42,060
and I'm excited about is how
well we can calibrate them.

17
00:00:42,060 --> 00:00:45,810
Because, getting the absolute
flux calibration right means

18
00:00:45,810 --> 00:00:47,268
we've got all the
other bits right.

19
00:00:47,268 --> 00:00:47,768
Right?

20
00:00:47,768 --> 00:00:48,660
It's kind of the --

21
00:00:48,660 --> 00:00:50,430
I call it the canary
in the coal mine.

22
00:00:50,430 --> 00:00:53,910
If things are going wrong,
your flux doesn't work.

23
00:00:53,910 --> 00:00:56,760
And so, that was really nice to
see from all the instruments,

24
00:00:56,760 --> 00:01:00,500
that it is coming
together as we planned.
