00:00:04,000 --> 00:00:07,980
The universe, for all have learned about it,

3
00:00:08,000 --> 00:00:11,980
we have only just begun to reveal its secrets.

4
00:00:12,000 --> 00:00:15,980
What are dark matter and dark energy? How common are

5
00:00:16,000 --> 00:00:19,980
planetary arrangements like our own? And how many planets

6
00:00:20,000 --> 00:00:23,980
in our galaxy have the potential to harbor life?

7
00:00:24,000 --> 00:00:27,980
The Nancy Grace Roman Space Telescope will help answer these fundamental

8
00:00:28,000 --> 00:00:31,980
questions. Formerly known as WFIRST, the Roman

9
00:00:32,000 --> 00:00:35,980
Space Telescope is similar to Hubble, but with the benefit of 30

10
00:00:36,000 --> 00:00:39,980
years of technological improvement. Each image from its

11
00:00:40,000 --> 00:00:43,980
Wide Field Instrument will have the depth and clarity of Hubble’s best,

12
00:00:44,000 --> 00:00:47,980
but capture a sky area 100 times larger.

13
00:00:48,000 --> 00:00:51,980
The Roman Space Telescope will take the lead in exploring

14
00:00:52,000 --> 00:00:55,980
dark energy and dark matter. We only know they exist

15
00:00:56,000 --> 00:00:59,980
by their effects on observable matter, yet these two mysterious 

16
00:01:00,000 --> 00:01:03,980
components make up 95% of the universe.

17
00:01:04,000 --> 00:01:07,980
The Roman Space Telescope’s powerful 2.4 meter

18
00:01:08,000 --> 00:01:11,980
mirror and enormous field of view will also help us in the search

19
00:01:12,000 --> 00:01:15,980
for planets beyond our solar system, or exoplanets.

20
00:01:16,000 --> 00:01:19,980
It will watch for gravitational microlensing events, caused when a

21
00:01:20,000 --> 00:01:23,980
planet and its host star pass in front of a background star.

22
00:01:24,000 --> 00:01:27,980
Such events are rare, so catching them requires watching large

23
00:01:28,000 --> 00:01:31,980
swaths of the sky. To deepen its study of

24
00:01:32,000 --> 00:01:35,980
exoplanets, the Roman Space Telescope will house a beyond state-of-the-art

25
00:01:36,000 --> 00:01:39,980
coronagraph that will directly image and analyze

26
00:01:40,000 --> 00:01:43,980
Neptune-size planets in orbits slightly larger than Earth’s —

27
00:01:44,000 --> 00:01:47,980
a dramatic improvement over current capabilities.

28
00:01:48,000 --> 00:01:51,980
The Nancy Grace Roman Space Telescope will help us answer

29
00:01:52,000 --> 00:01:55,980
many of the biggest cosmic questions. Its wide-field view and

30
00:01:56,000 --> 00:01:59,980
coronagraph will complement missions like NASA’s James Webb Space Telescope,

31
00:02:00,000 --> 00:02:03,980
and Transiting Exoplanet Survey Satellite, TESS.

32
00:02:04,000 --> 00:02:07,980
The Roman Space Telescope will be an indispensable 

33
00:02:08,000 --> 00:02:11,980
part of space science during the next decade and beyond.
