2 THE BOOK THAT LAUNCHED A THOUSAND WHITE PAPERS

3 THE LUVOIR TEAM

4 WE RE HALFWAY DONE

5 THE STORY OF LIFE IN THE UNIVERSE

6 The most effective way to do it, is to do it. -AMELIA EARHART

7 LUVOIR It s Large. It s Powerful. It s Serviceable. It s Open.

8 LUVOIR It s Large. It s Powerful. It s Serviceable. It s Open.

9 HISTORICAL POINT NO MATTER WHAT YOU COME UP WITH, LYMAN SPITZER ALREADY THOUGHT OF IT Spitzer, 1946

10 IT S LARGE LUVOIR-A LUVOIR-A + SLS Block 2 Fairing

11 SLS BLOCK 2

12 NO, REALLY. IT S LARGE

13 THAT S A BIG SUNSHIELD

14 LUVOIR-B ~8 METER OFF-AXIS

15 LUVOIR IN A NUTSHELL It s Large. It s Powerful. It s Serviceable. It s Open.

16 IT S POWERFUL 4 instruments being studied for architecture A (15m) ECLIPS: High contrast (10-10 ) NUV/VIS/NIR coronagraph with imaging and integral field spectroscopy HDI: ~3 Gigapixel, Nyquist sampled simultaneous dual-channel (NUV/ VIS, NIR) 2 x3 imager reaching V=31 (10!) in 1 hour mas/pix UV, 8.25 mas/pix NIR) LUMOS: FUV/NUV FUV imager able to observe hundreds of objects simultaneously, reaching FUV mag=21 (10!) in <1 hour at R=30,000 and "=1300Å POLLUX: (European Instrument Study): High resolution (R~120,000) UV spectropolarimiter

17 IT S POWERFUL

18 LUVOIR IN A NUTSHELL It s Large. It s Powerful. It s Serviceable. It s Open.

19 IT S SERVICEABLE Observatory designed from the beginning to have swappable instruments and some telescope components

20 LUVOIR IN A NUTSHELL It s Large. It s Powerful. It s Serviceable. It s Open.

21 IT S OPEN LUVOIR will be a Guest Observer driven facility analogous to NASA s Great Observatories

22 BUT WHY?

34 TWO EXTREMES Either case demands a large survey

35 STARS & STAR FORMATION

36 FROM NURSERIES TO CRADLES Proto-Planetary Disks in the nearest Star Forming Regions with HST A 15.1 m LUVOIR can do this anywhere in the Milky Way

37 LIFE S BUILDING BLOCKS IN THE DISKS

38 THE RISE OF THE PERIODIC TABLE Figure 6.12: Comparison of distances for which LUVOIR abundances in metal-poor giants to examine the origins of the are best studied in the UV; many of these stars are so metal po too intrinsically weak, but stronger UV lines of Fe, Mg, challenging, expensive observations for Hubble since the stars LUMOS will push these limits to ~ 20 kpc, a significant frac halo.

48 FOUR BRIEF POINTS

49 POINT #1 JUST BECAUSE YOU CAN, DOESN T MEAN YOU WILL do the impossible both ways HST Cycles 17-23

50 POINT #2 WE HAVE ALWAYS HAD LARGER TELESCOPES ON THE GROUND. THAT S OK but what will the community landscape be in 2035?

51 Scientific Uses of the Large Space Telescope POINT #3 THE LUVOIR STDT MAY NOT KNOW WHAT THE MOST IMPORTANT SCIENCE OF 2035, 2045, AND 2055 IS Copyright National Academy of Sciences. All rights reserved. we must build powerful and flexible

52 POINT #4 WE CAN STAND ON THE SHOULDERS OF GIANTS we have significant heritage to leverage

53 WHAT S NEXT?
