1 00:00:00,870 --> 00:00:04,423 - [Michael] And let's go ahead with Gary, John and Eric. 2 00:00:05,620 --> 00:00:06,750 - [Gary] Thank you, Michael. 3 00:00:06,750 --> 00:00:08,150 Hi, I'm Gary Blackwood. 4 00:00:08,150 --> 00:00:11,640 I'm the program manager for Exoplanet Exploration, 5 00:00:11,640 --> 00:00:14,330 and John Callas, Eric Mamajek, and I 6 00:00:14,330 --> 00:00:15,960 would like to give you some program updates 7 00:00:15,960 --> 00:00:17,010 that will be of interest to you. 8 00:00:17,010 --> 00:00:17,843 Next. 9 00:00:22,020 --> 00:00:24,930 So ExEP is NASA search for habitable planets and life 10 00:00:24,930 --> 00:00:26,490 beyond our solar system. 11 00:00:26,490 --> 00:00:29,140 They're a part of the NASA astrophysics division 12 00:00:29,140 --> 00:00:30,970 and our purpose, 13 00:00:30,970 --> 00:00:32,180 as described in the charter 14 00:00:32,180 --> 00:00:34,030 from the astrophysics division, 15 00:00:34,030 --> 00:00:35,720 to discover planets around other stars, 16 00:00:35,720 --> 00:00:36,970 characterize their properties 17 00:00:36,970 --> 00:00:41,030 in terms of planets that can support and harbor life. 18 00:00:41,030 --> 00:00:44,670 So this program serves the science community and NASA 19 00:00:44,670 --> 00:00:45,813 through two functions. 20 00:00:48,240 --> 00:00:51,930 First as a focal point for exoplanet science and technology, 21 00:00:51,930 --> 00:00:55,820 and second, by integrating into a cohesive strategy 22 00:00:55,820 --> 00:00:57,163 for future discoveries. 23 00:00:58,170 --> 00:00:59,003 Next. 24 00:01:03,860 --> 00:01:07,000 This arc of mission describes a rich tapestry 25 00:01:07,000 --> 00:01:09,980 of past current and hopefully future missions 26 00:01:09,980 --> 00:01:10,813 for exoplanets, 27 00:01:10,813 --> 00:01:14,660 and most of you, have, are, or will be involved 28 00:01:14,660 --> 00:01:16,423 in these missions. 29 00:01:17,730 --> 00:01:19,430 While the missions are managed 30 00:01:19,430 --> 00:01:21,590 throughout the different programs 31 00:01:21,590 --> 00:01:23,870 in the astrophysics division, 32 00:01:23,870 --> 00:01:28,870 this program serves the function of a focal point 33 00:01:28,960 --> 00:01:33,650 for science technology through technology investments, 34 00:01:33,650 --> 00:01:36,710 technology gap list, 35 00:01:36,710 --> 00:01:38,470 you'll hear about the technology gap list 36 00:01:38,470 --> 00:01:40,280 and science gap list. 37 00:01:40,280 --> 00:01:43,580 We also serve the precursor and follow up songs 38 00:01:43,580 --> 00:01:44,420 for those missions. 39 00:01:44,420 --> 00:01:45,910 And some of the facilities for that 40 00:01:45,910 --> 00:01:47,573 are shown across the bottom. 41 00:01:48,440 --> 00:01:51,410 And importantly we serve the community 42 00:01:51,410 --> 00:01:54,880 through functions and events such as this ExoPAG. 43 00:01:54,880 --> 00:01:58,490 And I'm delighted by the number of participants 44 00:01:58,490 --> 00:02:00,680 that I see in his WebEx meeting. 45 00:02:00,680 --> 00:02:01,513 Next. 46 00:02:03,930 --> 00:02:08,930 Our legacy mission in the program is Kepler K2. 47 00:02:09,140 --> 00:02:12,800 And though the flight mission ended in 2018, 48 00:02:12,800 --> 00:02:14,070 when the fuel was exhausted, 49 00:02:14,070 --> 00:02:15,570 the project has continued 50 00:02:21,718 --> 00:02:23,250 to process the K2 data, 51 00:02:23,250 --> 00:02:25,890 through the latest pipeline version 52 00:02:25,890 --> 00:02:30,690 and to archive the data at MAST. 53 00:02:30,690 --> 00:02:35,460 NExScI serves the K2 candidates, through the archive. 54 00:02:35,460 --> 00:02:37,330 And we're delighted to report 55 00:02:37,330 --> 00:02:40,570 that the community has shared more than 5,200 observations 56 00:02:40,570 --> 00:02:43,510 and nearly 600,000 files, 57 00:02:43,510 --> 00:02:45,833 through the ExoFOP-K2 portal. 58 00:02:47,570 --> 00:02:49,688 This is a good time to reflect on the mission 59 00:02:49,688 --> 00:02:54,688 and thank everyone who worked on Kepler and K2, 60 00:02:55,690 --> 00:02:56,960 to make the mission succeed 61 00:02:56,960 --> 00:02:59,033 and transform the exoplanet field, 62 00:03:00,500 --> 00:03:04,410 including the world science community to support the mission 63 00:03:04,410 --> 00:03:05,770 with the follow up observations, 64 00:03:05,770 --> 00:03:08,660 open source software and amazing discoveries. 65 00:03:08,660 --> 00:03:12,823 A big thank you to everyone for transforming this field. 66 00:03:14,090 --> 00:03:14,923 Next. 67 00:03:16,570 --> 00:03:19,980 This graphic describes the breadth of the program 68 00:03:19,980 --> 00:03:22,860 that serves the functions I described earlier, 69 00:03:22,860 --> 00:03:25,210 as a focal point for science and technology 70 00:03:25,210 --> 00:03:28,060 and an integration for a cohesive strategy, 71 00:03:28,060 --> 00:03:29,670 for future discoveries. 72 00:03:29,670 --> 00:03:31,963 So beyond the missions and mission concepts, 73 00:03:35,920 --> 00:03:40,210 the program funds technology development and chronograph, 74 00:03:40,210 --> 00:03:43,220 and star shade for exoplanet direct imaging. 75 00:03:43,220 --> 00:03:46,940 And now through the EPRP initiative for the technology 76 00:03:48,550 --> 00:03:51,323 for precision rate of velocity. 77 00:03:52,550 --> 00:03:55,330 The program also has an exciting and productive 78 00:03:55,330 --> 00:03:57,063 exoplanet communications, 79 00:03:58,020 --> 00:03:59,960 that I'll have a slide or two on later. 80 00:03:59,960 --> 00:04:02,640 But next I'd like to describe a couple of slides, 81 00:04:02,640 --> 00:04:05,720 about the NASA Exoplanet Science Institute, NExScI, 82 00:04:07,890 --> 00:04:11,920 at the Caltech campus who are the public interface 83 00:04:11,920 --> 00:04:14,413 and professional interface of the program. 84 00:04:16,140 --> 00:04:19,170 So one on this slide, I wanna communicate four points, 85 00:04:19,170 --> 00:04:21,930 that the exoplanet archive is operational 86 00:04:21,930 --> 00:04:24,670 and actively ingesting new planets. 87 00:04:24,670 --> 00:04:26,930 And second that the archive had fared very well 88 00:04:26,930 --> 00:04:30,570 in the recent NASA archives review. 89 00:04:30,570 --> 00:04:31,480 And that one on the right 90 00:04:31,480 --> 00:04:34,223 shows the growth in the use of the NASA archive. 91 00:04:35,610 --> 00:04:40,140 The NASA archive is being upgraded 92 00:04:40,140 --> 00:04:43,450 based on the feedback from prior ExoPAG meetings. 93 00:04:43,450 --> 00:04:45,940 Here we highlight the planetary systems table, 94 00:04:45,940 --> 00:04:48,324 and the composite parameters table. 95 00:04:48,324 --> 00:04:51,220 And finally, the ExoFOP followup observing program 96 00:04:51,220 --> 00:04:53,440 continues to support the community, 97 00:04:53,440 --> 00:04:56,590 through a number of different facilities. 98 00:04:56,590 --> 00:04:59,100 What are these observing facilities? 99 00:04:59,100 --> 00:04:59,933 Next. 100 00:05:03,800 --> 00:05:08,310 So the observing resources are really exoplanets and more. 101 00:05:08,310 --> 00:05:10,691 The more part is the Keck strategic programs 102 00:05:10,691 --> 00:05:13,880 from all areas of astrophysics and planetary science. 103 00:05:13,880 --> 00:05:18,400 NExScI manages one sixth of the Keck single aperture time 104 00:05:18,400 --> 00:05:20,030 on (indistinct). 105 00:05:20,030 --> 00:05:21,603 The NN-Explore program, 106 00:05:23,410 --> 00:05:26,830 supports test follow up in a number of facilities 107 00:05:26,830 --> 00:05:29,170 on when there's the NEID instrument, 108 00:05:29,170 --> 00:05:32,053 for precision rate of velocity being commissioned soon. 109 00:05:32,980 --> 00:05:35,210 There's NESSI for high resolution imaging 110 00:05:35,210 --> 00:05:38,270 managed by Steve Howell at the Ames research center, 111 00:05:38,270 --> 00:05:41,580 along with instruments, Gemini North and South. 112 00:05:41,580 --> 00:05:43,140 And there's a number of Southern hemisphere 113 00:05:43,140 --> 00:05:45,640 radial velocity opportunities, 114 00:05:45,640 --> 00:05:48,660 that the program has responded to the community and funded 115 00:05:48,660 --> 00:05:51,260 in order to provide test followup and access 116 00:05:51,260 --> 00:05:53,432 for you as astronomers in the South. 117 00:05:53,432 --> 00:05:57,693 I'd like to call out an upcoming special call, 118 00:05:58,820 --> 00:06:03,060 for 285 hours available on Minerva-Australis. 119 00:06:03,060 --> 00:06:05,630 That call will go active immediately 120 00:06:05,630 --> 00:06:07,113 following this presentation. 121 00:06:08,420 --> 00:06:10,573 The due date is July 16th. 122 00:06:11,950 --> 00:06:12,783 Next. 123 00:06:14,680 --> 00:06:15,513 And finally, 124 00:06:15,513 --> 00:06:19,423 I'll mention that NExScI support community conferences, 125 00:06:20,610 --> 00:06:21,790 the second summer workshop, 126 00:06:21,790 --> 00:06:24,463 very timely and extreme precision radial velocity, 127 00:06:25,940 --> 00:06:28,940 calendar virtual exoplanet talks, 128 00:06:28,940 --> 00:06:32,060 and looking forward to an exoplanet demographics conference 129 00:06:32,060 --> 00:06:32,893 in November. 130 00:06:34,260 --> 00:06:35,093 Next. 131 00:06:37,790 --> 00:06:40,840 The program communications team has been very active 132 00:06:40,840 --> 00:06:42,620 through NASA at home. 133 00:06:42,620 --> 00:06:44,533 There's two of my favorite products, 134 00:06:47,290 --> 00:06:49,130 Exoplanet Scavenger Hunt 135 00:06:49,130 --> 00:06:53,300 and the Exoplanet travel Bureau coloring book. 136 00:06:53,300 --> 00:06:54,370 There's other links here. 137 00:06:54,370 --> 00:06:55,203 Next. 138 00:06:57,360 --> 00:07:00,360 Perhaps some of you have the Exoplanet travel Bureau posters 139 00:07:00,360 --> 00:07:04,170 at work or at home, or in some digital format, 140 00:07:04,170 --> 00:07:09,170 but do you have the Exoplanet galaxy of horror poster series 141 00:07:09,760 --> 00:07:12,020 that we released last October? 142 00:07:12,020 --> 00:07:13,480 These are the first two in the series. 143 00:07:13,480 --> 00:07:15,080 And yes, I'm dropping a big hint, 144 00:07:15,080 --> 00:07:17,090 there'll be another poster coming out very soon, 145 00:07:17,090 --> 00:07:18,440 I'm told on good authority. 146 00:07:19,610 --> 00:07:21,270 With that in the interest of time, 147 00:07:21,270 --> 00:07:26,030 I'd like to turn over the floor to John Callas, 148 00:07:26,030 --> 00:07:28,660 my colleague here in the Exoplanet Exploration program, 149 00:07:28,660 --> 00:07:31,703 and he's the NN-Explore manager. 150 00:07:33,330 --> 00:07:34,700 - [John] Thank you Gary. 151 00:07:34,700 --> 00:07:36,773 And next slide, Jennifer. 152 00:07:37,640 --> 00:07:40,450 So is there are three components to NN-Explore, 153 00:07:40,450 --> 00:07:41,283 and by the way, 154 00:07:41,283 --> 00:07:44,740 NN-Explore stands for the NASA NSF exoplanet 155 00:07:44,740 --> 00:07:46,453 observational research program. 156 00:07:47,740 --> 00:07:50,520 The first component is the NEID spectrograph 157 00:07:50,520 --> 00:07:54,070 at the WIYN telescope, and this is a brief update on that. 158 00:07:54,070 --> 00:07:56,080 The NEID instrument has been delivered 159 00:07:56,080 --> 00:07:58,130 along with the port adapter to the WIYN telescope. 160 00:07:58,130 --> 00:08:00,260 You can see a photograph in the upper right there, 161 00:08:00,260 --> 00:08:01,760 of the instrument rolling 162 00:08:01,760 --> 00:08:03,550 into the basement of the telescope. 163 00:08:03,550 --> 00:08:05,340 Commissioning was underway 164 00:08:05,340 --> 00:08:06,943 when the pandemic interrupted things. 165 00:08:06,943 --> 00:08:11,943 So we have to wait until Kitt Peak reopens 166 00:08:12,040 --> 00:08:15,300 before we can resume the commissioning effort. 167 00:08:15,300 --> 00:08:19,970 But as it stands right now we're hopeful (indistinct) 168 00:08:19,970 --> 00:08:24,260 for in late 2020B, and the 2020B selections 169 00:08:24,260 --> 00:08:26,013 will be announced shortly. 170 00:08:27,250 --> 00:08:29,800 And we expect to complete commissioning 171 00:08:29,800 --> 00:08:33,260 by the January, February, 2021 timeframe, 172 00:08:33,260 --> 00:08:38,070 in time for the start of semester 2021A, 173 00:08:38,070 --> 00:08:42,530 where we'll have the full GO and full GTO available. 174 00:08:42,530 --> 00:08:46,360 We will be releasing the newest standard stars 175 00:08:46,360 --> 00:08:48,790 that are observed every day, immediately, 176 00:08:48,790 --> 00:08:51,570 along with all the solar observations every day. 177 00:08:51,570 --> 00:08:52,950 So we have a solar telescope, 178 00:08:52,950 --> 00:08:56,280 you can see that down in the lower right of this frame. 179 00:08:56,280 --> 00:09:01,280 And we did complete a first light image of 51 peg, 180 00:09:01,720 --> 00:09:04,470 that was announced back at the winter AAS, 181 00:09:04,470 --> 00:09:06,670 you see that the lower left. 182 00:09:06,670 --> 00:09:09,000 So we're eager to resume the commissioning activities 183 00:09:09,000 --> 00:09:11,240 and begin our observations. 184 00:09:11,240 --> 00:09:14,070 You can find more about NN-Explorer at the website shown 185 00:09:14,070 --> 00:09:16,240 at the bottom of the frame. 186 00:09:16,240 --> 00:09:17,203 Next slide, please. 187 00:09:19,040 --> 00:09:20,340 Gary mentioned some of this. 188 00:09:20,340 --> 00:09:21,570 So I'll go through it quickly. 189 00:09:21,570 --> 00:09:24,740 We do have several aspects of this program 190 00:09:24,740 --> 00:09:27,740 that support test follow up. 191 00:09:27,740 --> 00:09:30,260 We have our Southern radial velocity effort, 192 00:09:30,260 --> 00:09:33,940 which has the three telescopes SMARTS-Chiron, ATT-Veloce, 193 00:09:33,940 --> 00:09:35,303 and now MINERVA-Australis. 194 00:09:36,477 --> 00:09:38,810 And we also support the high resolution imaging, 195 00:09:38,810 --> 00:09:41,480 the spectral imaging, both on WIYN, Gemini North 196 00:09:41,480 --> 00:09:42,860 and Gemini South. 197 00:09:42,860 --> 00:09:44,360 Again, you can go to that same length 198 00:09:44,360 --> 00:09:47,330 to find out more about all of these. 199 00:09:47,330 --> 00:09:49,630 But let me talk about the third aspect, 200 00:09:49,630 --> 00:09:53,690 which is the extreme precision radial velocity. 201 00:09:53,690 --> 00:09:56,150 I trust you all are aware that the National Academy's 202 00:09:56,150 --> 00:09:59,010 came out with the exoplanet science strategy. 203 00:09:59,010 --> 00:10:01,020 And in that they referenced 204 00:10:01,020 --> 00:10:04,420 that masses is the most important fundamental property 205 00:10:04,420 --> 00:10:05,710 of a planet. 206 00:10:05,710 --> 00:10:06,907 And radial velocity of course, 207 00:10:06,907 --> 00:10:09,010 is one of the ways to determine that. 208 00:10:09,010 --> 00:10:12,610 So the recommendation was that NASA and NSF 209 00:10:12,610 --> 00:10:14,550 should establish a strategic initiative 210 00:10:14,550 --> 00:10:17,530 in extreme precision radial velocity, 211 00:10:17,530 --> 00:10:19,040 to develop methods or facilities 212 00:10:19,040 --> 00:10:21,860 for measuring the masses of temperate terrestrial planets, 213 00:10:21,860 --> 00:10:23,750 orbiting sun-like stars. 214 00:10:23,750 --> 00:10:25,130 So in response to that, 215 00:10:25,130 --> 00:10:28,120 we formed a working group of about 36 experts 216 00:10:28,120 --> 00:10:30,160 from throughout the world. 217 00:10:30,160 --> 00:10:32,030 We had eight subgroups 218 00:10:32,030 --> 00:10:35,900 that made up of this collection of expertise, 219 00:10:35,900 --> 00:10:37,580 that focused on different aspects 220 00:10:37,580 --> 00:10:39,760 of extreme precision radial velocity. 221 00:10:39,760 --> 00:10:43,090 We held three face-to-face multi-day workshops, 222 00:10:43,090 --> 00:10:46,820 and plus a uncountable number of teleconferences 223 00:10:46,820 --> 00:10:51,120 to develop a plan, but you'll hear more about, 224 00:10:51,120 --> 00:10:53,860 that NExScI made that very exciting announcement 225 00:10:53,860 --> 00:10:56,010 that NASA is going forward with some funding. 226 00:10:56,010 --> 00:10:57,210 And you can see a photograph there 227 00:10:57,210 --> 00:10:59,890 of some of the participants in that workshop. 228 00:10:59,890 --> 00:11:01,300 Next slide. 229 00:11:01,300 --> 00:11:03,623 So by way of sort of summary, 230 00:11:05,260 --> 00:11:08,320 what limits our ability to use radial velocity 231 00:11:08,320 --> 00:11:11,710 to achieve the precision mass measurements 232 00:11:11,710 --> 00:11:15,610 of smaller planets, falls into three main areas. 233 00:11:15,610 --> 00:11:18,020 One is photon noise. 234 00:11:18,020 --> 00:11:19,860 The other is facility limitations, 235 00:11:19,860 --> 00:11:22,970 instrumentation limitations, atmospheric lyrics. 236 00:11:22,970 --> 00:11:25,320 And then the third is stellar activity 237 00:11:25,320 --> 00:11:28,690 or what the star is doing to complicate the signal. 238 00:11:28,690 --> 00:11:29,773 Next time step. 239 00:11:32,630 --> 00:11:36,430 So we know that we can address the photon noise 240 00:11:36,430 --> 00:11:37,720 or the photon counting issue 241 00:11:37,720 --> 00:11:40,640 by a telescope aperture and cadence. 242 00:11:40,640 --> 00:11:41,996 And this will get to the strategy 243 00:11:41,996 --> 00:11:44,120 of facilities that we'll use, 244 00:11:44,120 --> 00:11:45,710 and the size of the apertures, 245 00:11:45,710 --> 00:11:48,600 and the amount of access we have to those facilities 246 00:11:48,600 --> 00:11:49,700 over time. 247 00:11:49,700 --> 00:11:50,713 Next time step. 248 00:11:52,450 --> 00:11:54,510 And then of course facility limitations 249 00:11:54,510 --> 00:11:56,050 gets to instrumentation. 250 00:11:56,050 --> 00:11:59,150 And that brings up the question 251 00:11:59,150 --> 00:12:03,930 of investigating technology and also a telluric, 252 00:12:03,930 --> 00:12:04,950 atmospheric currents. 253 00:12:04,950 --> 00:12:06,530 Next time step, please. 254 00:12:06,530 --> 00:12:08,000 - [Michael] John there's three minutes left 255 00:12:08,000 --> 00:12:10,250 in your collective presentation. 256 00:12:10,250 --> 00:12:11,610 - [John] I want to wrap up. 257 00:12:11,610 --> 00:12:14,700 And then Stellar variability and data analytics 258 00:12:14,700 --> 00:12:15,533 is the third. 259 00:12:15,533 --> 00:12:18,150 So if I do the next step, please, 260 00:12:18,150 --> 00:12:21,420 you'll see that the first two items 261 00:12:21,420 --> 00:12:23,230 drive a set of proposed architectures 262 00:12:23,230 --> 00:12:24,850 that you'll hear about tomorrow, 263 00:12:24,850 --> 00:12:26,600 when we talk about the PRV. 264 00:12:26,600 --> 00:12:28,620 And then last next time step, 265 00:12:28,620 --> 00:12:31,580 is then there's a set of proposed research elements. 266 00:12:31,580 --> 00:12:33,900 And again, you'll hear more about that 267 00:12:34,770 --> 00:12:37,723 with the PRV discussion tomorrow. 268 00:12:38,650 --> 00:12:41,610 So with that I'll pass it off to Eric. 269 00:12:41,610 --> 00:12:42,593 Thanks very much. 270 00:12:46,400 --> 00:12:48,243 - [Eric] Wait for my slides to come up. 271 00:12:59,610 --> 00:13:00,443 - [Jennifer] I'm working on it Eric, 272 00:13:00,443 --> 00:13:01,792 give me a few seconds to download. 273 00:13:01,792 --> 00:13:03,730 - [Eric] No worries, I'll just introduce myself here. 274 00:13:03,730 --> 00:13:04,820 So my name is Eric Mamajek, 275 00:13:04,820 --> 00:13:06,260 I'm deputy program chief scientist 276 00:13:06,260 --> 00:13:09,200 to the NASA Exoplanet exploration program. 277 00:13:09,200 --> 00:13:12,560 I'm going to very briefly cover a few topics 278 00:13:12,560 --> 00:13:17,560 relevant to the science program of ExEP. 279 00:13:19,840 --> 00:13:23,970 Next slide. 280 00:13:23,970 --> 00:13:26,330 So the NASA exoplanet exploration program 281 00:13:26,330 --> 00:13:30,520 has a science plan that helps NASA, astrophysics, 282 00:13:30,520 --> 00:13:31,860 know where the advancement of science 283 00:13:31,860 --> 00:13:35,880 would most help advance NASA's program goals. 284 00:13:35,880 --> 00:13:38,920 Most important of these documents is a science gap list. 285 00:13:38,920 --> 00:13:41,850 There's three documents actually that we update, 286 00:13:41,850 --> 00:13:44,400 the science gap list is updated every year. 287 00:13:44,400 --> 00:13:45,490 What's a science gap? 288 00:13:45,490 --> 00:13:46,323 That's the difference between 289 00:13:46,323 --> 00:13:48,000 the knowledge needed to define requirements 290 00:13:48,000 --> 00:13:50,260 for specified future NASA planet missions, 291 00:13:50,260 --> 00:13:52,120 and the current state of the art or knowledge, 292 00:13:52,120 --> 00:13:54,090 which is needed to enhance the science return 293 00:13:54,090 --> 00:13:57,380 of current and future NASA Exoplanet missions. 294 00:13:57,380 --> 00:13:59,620 So this is a tactical document. 295 00:13:59,620 --> 00:14:00,810 We're not reinventing the wheel. 296 00:14:00,810 --> 00:14:02,410 This is not new strategy. 297 00:14:02,410 --> 00:14:03,640 We've incorporated inputs 298 00:14:03,640 --> 00:14:08,640 from the exoplanet science strategy NAS study, 299 00:14:08,960 --> 00:14:11,920 and factored in massive science plans. 300 00:14:11,920 --> 00:14:14,662 And so we're identifying the science areas 301 00:14:14,662 --> 00:14:16,313 that need more attention. 302 00:14:17,950 --> 00:14:20,890 So there's the link for the documents 303 00:14:20,890 --> 00:14:23,170 and the science plan documents, 304 00:14:23,170 --> 00:14:25,760 were mentioned in the 2020 XRP call. 305 00:14:25,760 --> 00:14:26,593 Next. 306 00:14:29,110 --> 00:14:32,370 So here's the three documents. 307 00:14:32,370 --> 00:14:33,450 And again, the most important one here 308 00:14:33,450 --> 00:14:34,307 is the science gap list. 309 00:14:34,307 --> 00:14:37,030 The science plan appendix is a much longer document 310 00:14:37,030 --> 00:14:38,960 that will be updated every few years. 311 00:14:38,960 --> 00:14:40,800 The next update will probably come after 312 00:14:40,800 --> 00:14:44,090 the 2020 (indistinct) comes out. 313 00:14:44,090 --> 00:14:44,923 Next. 314 00:14:46,300 --> 00:14:48,490 And I just have a list of the science gaps, 315 00:14:48,490 --> 00:14:49,520 but I won't go through them, 316 00:14:49,520 --> 00:14:50,800 but most of them will be topics 317 00:14:50,800 --> 00:14:53,793 near and dear to your hearts as exoplanet astronomers. 318 00:14:54,670 --> 00:14:55,503 Next. 319 00:14:59,280 --> 00:15:00,170 So over the last year, 320 00:15:00,170 --> 00:15:02,920 we solicited input from the community 321 00:15:02,920 --> 00:15:05,600 and incorporated that into revisions, the science gap lists, 322 00:15:05,600 --> 00:15:06,433 last fall. 323 00:15:06,433 --> 00:15:09,640 We just posted a new version of Gap list earlier this year. 324 00:15:09,640 --> 00:15:12,800 We're actually reopening the input window 325 00:15:12,800 --> 00:15:14,860 for community input now. 326 00:15:14,860 --> 00:15:17,640 So please send us any comments on the science gap list, 327 00:15:17,640 --> 00:15:18,497 through the end of September, 328 00:15:18,497 --> 00:15:21,410 and feel free to reach out to Karl Stapelfeld, 329 00:15:21,410 --> 00:15:23,190 the chief scientist, or myself. 330 00:15:23,190 --> 00:15:26,810 And we'll also be asking for the ExoPAG C members, 331 00:15:26,810 --> 00:15:28,370 also for input. 332 00:15:28,370 --> 00:15:29,203 Next. 333 00:15:30,530 --> 00:15:34,660 I wanted to briefly update you on results from LBTI. 334 00:15:34,660 --> 00:15:37,070 Knowing interferometer, this is a big experiment 335 00:15:37,070 --> 00:15:40,740 to measure the levels of exozodi around nearby stars. 336 00:15:40,740 --> 00:15:42,030 You've probably seen some of these results 337 00:15:42,030 --> 00:15:43,740 in previous ExoPAGs. 338 00:15:43,740 --> 00:15:46,513 The final report of the HOST study is out, 339 00:15:46,513 --> 00:15:50,270 it's a survey of a few dozen nearby stars. 340 00:15:50,270 --> 00:15:52,890 The statistical results seems to be that on average 341 00:15:52,890 --> 00:15:56,520 the Zodi levels of dust in the Hab zones of nearby stars 342 00:15:56,520 --> 00:15:58,173 is at the fuse Zodi level. 343 00:15:59,220 --> 00:16:03,850 And this is a key input for helping design missions 344 00:16:03,850 --> 00:16:07,150 for a direct imaging of planets. 345 00:16:07,150 --> 00:16:09,850 The HOST team is continuing to work on papers. 346 00:16:09,850 --> 00:16:10,683 Next. 347 00:16:11,770 --> 00:16:13,750 One of the key questions is, 348 00:16:13,750 --> 00:16:15,100 should NASA invest further 349 00:16:15,100 --> 00:16:17,420 to reduce exozodiacal uncertainties? 350 00:16:17,420 --> 00:16:21,520 So we've asked, university of Arizona LBTI team, 351 00:16:21,520 --> 00:16:24,120 to deliver report on the sensitivity of LBTI 352 00:16:24,120 --> 00:16:26,090 and what the prospects are. 353 00:16:26,090 --> 00:16:28,670 They have found a few sources of uncertainty 354 00:16:28,670 --> 00:16:31,080 that seem to dominate their air budget. 355 00:16:31,080 --> 00:16:32,600 There seems to be a feasible path 356 00:16:32,600 --> 00:16:36,060 to get factor of two or three improvement. 357 00:16:36,060 --> 00:16:40,563 They're also doing some work on testing a new detector. 358 00:16:41,760 --> 00:16:46,140 We'll need to see what the Decadal delivers 359 00:16:46,140 --> 00:16:50,068 in terms of whether a direct imaging mission 360 00:16:50,068 --> 00:16:51,793 is in the cards. 361 00:16:52,830 --> 00:16:55,040 But there's some big questions here on, you know, 362 00:16:55,040 --> 00:16:58,040 should the HOST survey be repeated with an upgraded LBTI, 363 00:16:58,040 --> 00:17:02,810 or are there other avenues for studying exozodiacal dust? 364 00:17:02,810 --> 00:17:05,520 There's a few of the options there. 365 00:17:05,520 --> 00:17:07,260 So input on that is helpful. 366 00:17:07,260 --> 00:17:08,093 Next. 367 00:17:10,360 --> 00:17:13,330 We track the suggestions from the ExoPAG. 368 00:17:13,330 --> 00:17:14,770 This is just one slide. 369 00:17:14,770 --> 00:17:16,460 So you'll see several more slides like this 370 00:17:16,460 --> 00:17:18,990 listing suggestions from ExoPAGs. 371 00:17:18,990 --> 00:17:20,460 You'll see more in the business meeting. 372 00:17:20,460 --> 00:17:22,260 This is just showing that some of the suggestions 373 00:17:22,260 --> 00:17:23,930 that percolate through the ExoPAGs 374 00:17:23,930 --> 00:17:25,640 actually turn into action. 375 00:17:25,640 --> 00:17:29,500 Some of them turn into new study groups and new reports. 376 00:17:29,500 --> 00:17:31,930 Some of them are much easier to close. 377 00:17:31,930 --> 00:17:33,380 We're tracking the suggestions. 378 00:17:33,380 --> 00:17:36,720 If you go into Slido, you can add new suggestions 379 00:17:36,720 --> 00:17:38,210 in the ideas section. 380 00:17:38,210 --> 00:17:40,500 So please use that to collect any input. 381 00:17:40,500 --> 00:17:42,100 We do take these very seriously. 382 00:17:43,010 --> 00:17:46,440 And there's been some positive results 383 00:17:46,440 --> 00:17:48,370 from suggestions at these meetings. 384 00:17:48,370 --> 00:17:49,203 Next. 385 00:17:50,820 --> 00:17:52,850 And I'll just close with some of the websites. 386 00:17:52,850 --> 00:17:54,980 I think you're all already on the ExoPAG email list, 387 00:17:54,980 --> 00:17:57,110 so I wont advertise that any further, 388 00:17:57,110 --> 00:17:59,503 and I'll go to questions, thank you. 389 00:18:00,993 --> 00:18:03,910 - [Michael] Thanks, Eric, for making up so much time. 390 00:18:03,910 --> 00:18:05,380 I have one question actually, 391 00:18:05,380 --> 00:18:07,390 I think I'll direct that at John, 392 00:18:07,390 --> 00:18:12,390 about the rumors of a light leak for the NEID, 393 00:18:13,050 --> 00:18:16,113 and whether that will impact the commissioning schedule? 394 00:18:18,140 --> 00:18:20,220 - [John] There's no light leak. 395 00:18:20,220 --> 00:18:23,760 We do have a concern about some contamination 396 00:18:23,760 --> 00:18:26,770 on the face of the detector, 397 00:18:26,770 --> 00:18:29,130 that we're taking mitigation steps against, 398 00:18:29,130 --> 00:18:32,630 but no light leaks in the instrument. 399 00:18:32,630 --> 00:18:35,420 We are challenged of course by the delay 400 00:18:35,420 --> 00:18:38,140 from the COVID-19 standout. 401 00:18:38,140 --> 00:18:40,480 So as I mentioned, we need to get back to, 402 00:18:40,480 --> 00:18:42,180 get the instrument up and running. 403 00:18:43,650 --> 00:18:45,250 - [Michael] Thank you very much.
