- And then we move to our next and final talk for this first session, which will be given by Knicole Colon. And she has a slightly longer talk on JWST Exoplanet Science Update. I will give you two minute warning on your 15 minutes talk Knicole, thank you.

- There we go, I was still muted. Can you hear me now and see my slides okay?

- [Ilaria] Yes, I can hear and I can see the slide.

- Perfect, all right, great. So hello everyone. I want to first thank the organizers for the opportunity to give an update on Webb and some of its exoplanet science. First and foremost, I am just delighted and relieved and ecstatic to say that the James Webb Space Telescope is in fact now officially a space telescope. So you can see one of our last images of it here and as the background image. So it's just incredibly exciting. Okay, so over the next 16 slides or so I'm going to aim to summarize in less than 16 minutes what Webb has been through over the last 16 days since launch, I will also provide an overview of some of the activities and data that we have to look forward to in 2022. Okay, so if, just as like a recap of the last 16, well, a little longer than 16 days, if you hadn't seen them before, here are some beautiful images of Webb on earth that were some of the last ones we had when it was installed on the rocket and encapsulated in the fairing. You can see just, it's a beautiful telescope of course, I think we've all known that, but it was just incredibly exciting to get to this point. And then it was even more exciting of course, to get to launch. And so Webb successfully launched from Kourou on Christmas day, December 25th, 2021 about 16 days ago now. And there's been a lot going on. So right now we are currently at L+16 days, and I'm happy to report if you hadn't heard or been following that all major deployments have successfully completed actually as of this past Saturday. So this talk comes at a very good time, I think. And so I wanted to highlight on this slide here, some of the deployment activities that Webb has gone through, and this is just, a super quick rundown basically you can find a lot more information online about all of these activities that Webb has gone through, but they're basically all the deployments took place and successfully. So everything from initially right after launch and separation from the fairing, the Solar array was deployed we went to the deployable tower assembly had to be extended to move the telescope away from the sunshield. And we had the sunshield fully extended and deployed and tensioned with all five layers successfully separated and tensioned. And another big milestone was that the secondary mirror support structure unfolded and latched into place. And as well as the two primary wings, so primary mirror wings. And so the final wing was deployed and latched on Saturday. And that was the final major deployment. I will mention too, that in addition, there's been other activities going on again, you can see some of these online, but for example, one thing that wasn't a deployment necessarily, what was just equally important is that the MIRI instrument, the Mid-Infrared Instrument, its instrument control electronics were also powered on and the contamination control cover was unlocked and tested, opening and closing it successfully. So that was a big milestone for the MIRI instrument as well. Okay, so some of these milestones and steps you can follow along, there's a really cool website "Where is Webb" and you can click around and this is a screenshot from the website, as of about 11:00 AM Eastern this morning. So you can see at that time, Webb is almost 80% on its way to its orbit around L2. And you can see more information on this page about all the various deployments and both previous deployments and upcoming activities as well. So I just wanted to link it here because it's a really fun website. And I also wanted to point out that on its journey to L2, there's been a lot of really cool images and videos coming out. This is one example of an astronomy picture of the day that was put out on a new year's Eve. And you can see in the middle, hopefully you can see the middle there, a little gift here of Webb moving across the sky caught by this observer Malcolm Park. And I know that there have been other images and videos taken that are tracking Webb along this journey, including like I saw some on Twitter from Peter Platchy, and I think he's online today, so definitely, feel free to look at those and check those out. It's been really exciting to see the community following Webb, literally on its journey. Okay, so beyond its journey and deployments, we are here, we are at L+16, as I mentioned, and what's next, there's a lot left to do. So commissioning takes about six months in total. There is well, now that the deployments are done, there's still a period of time of course, Webb is traveling out to its final orbit around L2, it should reach there around L+29 days. And then there's a bunch of telescope commissioning that has to happen. And then all the science instruments get commissioned and approximately the last two of the six months of the commissioning period. So you can see some of these different time steps or milestones here. This kind of graph is credit to Jane Rigby. And there's a couple of things I wanted to point out here. One is that Webb is continuing the cool as it moves along its orbit and it's cooling passively right now. And we need the, well, we must wait for all the science instruments to get cold first to commission them, but also Webb, so this chart has a, just like a small gray period of cooling, but it actually continues to cool out to around L+100 days is when may expect that that's the final stabilization of the MIRI instrument. So I have a little note there on that. And then there's a lot of alignments in the mirrors. These are, that's the big things that has to happen next. There's 18 different hexagonal mirror segments that Webb has. And so we need to start aligning all of them and getting an in focus image and then doing final tweaks after stabilization. So there's a lot to do to commission the telescope itself, even though deployments have been successful. And then the science instruments, again, there's four of them, MIRI, NIRCam, NIRSpec and NIRISS and those all get commissioned heavily in the last two months of the period and then we start science. So I wanted to bring it back to of course, exoplanet science at the ExoPAG today, and just highlight that one of the commissioning activities, for example, that is going to be done to prepare us for Exoplanet science. And so this is commissioning the nearest SOSS mode, the Single Objects Slitless Spectroscopy mode, I think that's right, that is led by Nestor Espinoza. And it's going to be observing this giant, a hot Jupiter, HAT-P-14 b. And so there's a commissioning mode to commissioning observation to test the SOSS mode and make sure, it operates as expected basically to characterize the sensitivity and stability of the instrument in this mode for time-series observations. And this is one of many important commissioning activities that is designed to test the instruments, of course, so that we can get these time-series observations that are a big part of Webb's science portfolio. So this is just one example, and I just showed the transit light curve of the transit here just for reference. So that's only one example of commissioning activity. I don't have time to talk about others, but there are others happening both for time-series and direct imaging and after commissioning though, remember that six month period, there is the time when we start science right after. And the first science to be done is the Early Release Science programs. And there's some for time-series or transit observations and then there's some for direct imaging. And so I linked the Early Release Science transit program website here. So you can find a lot of great information they've had, the team has held it's really interesting data hackathons and webinars, and you can find a lot of information about these on their website. And they're also planning a data challenge for this spring so those details are to be announced soon. And this program is led by Natalie Bataliha and also Kevin Stevenson and Jacob Bean with lots of other active team members. And I just wanted to call out that one of their targets for the ERS program is a WASP-39b and a bunch of transit modes or transit observations in a bunch of different instrument modes, I should say, with multiple instruments. And this plot is showing the Hubble and Spitzer transmission spectrum of WASP-39b. And then I kind of just, cartooned the James Webb wavelength range in general over this, but this is a great target to observe it's well-characterized with Hubble and Spitzer but now we'll be able to characterize it with Webb and use it as a great benchmark to test all these different observing modes for future observations and especially prepare us for Cycle 2 as well. Okay. Also beyond time-series and transits, there is a lot of high contrast imaging to be done. And so there is Early Release Science Program for this as well. And this is led by Sasha Hinkley and Andrew Skemer and Beth Biller. And you can find some more information about this on the website, but also they recorded a webinar that's available YouTube. And so this is a screenshot of the webinar, from the webinar on the left. And you could just see how we have a lot of different representative data sets that are going to be collected just like for the time-series observations, but a lot of science enabling products as well. So there's going to be really from both of these ERS programs, going to be a lot of great products and training essentially that we're going to get out of this and testing of the instruments to enable great science. And I wanted to highlight on the ready two of the planned ERS targets to my knowledge, one is you can see a sphere discovery image and then some NIRCam and MIRI simulated images of this young planet. And then on the bottom is a disc system that is going to be observed as well. And this was, yeah, I believe it was a Hubble image here, but yeah, these are just two examples. And then there's a third target that they're observing as well, but lots of great things happening. So those data will all have no proprietary period, no exclusive access period and there'll be available, well they'll be scheduled, I should say, as early as possible after commissioning. Of course we know with transits, it depends on the oral period and the visibility window and all that for scheduling, but those will be available basically ASAP for the community to use. And then interspersed Cycle 1 normal observations will start. So these are guaranteed time observations and guest observer observations. And I just wanted to show this figure. I put together of a subset of these GTO/GO transiting exoplanet targets, just to highlight a lot of the small and cool ones that Webb will be observing either in transit or eclipse, when the planet goes behind the star, you can see basically a highlight is the whole track this one system will be observed, all seven planets in one way or another will be observed as well as a couple other or several other interesting ones. So this just gives you a flavor of the types of targets that Webb will be observing over the next year.

- [Ilaria] And Nicole, you have two minutes left.

- Okay, perfect. Okay, so that was a real quick rundown. Some things we can expect from, well really in the next six months with commissioning and then the Early Release Science, and then what we're going to start to get from Cycle 1 data. Thinking about the Astro2020 decadal report that came out, flying Webb, this is a great feat of engineering with the unfolding, deployable mirrors and the deployable sunshield, like all of these are literal feats of engineering and it's a great feat of technology now that we've demonstrated that this can be done in space, of course. And so that is really great progress thinking ahead to what future flagships might be developed. And so I just wanted to say on this point, beyond the engineering, I mean, Webb is really going to of course revolutionize our understanding of what exoplanets and discs are made of. It's got incredible infrared sensitivity but on the flip side it doesn't observe the optical and UV. So we know hopefully that Hubble's going to be continuing to operate as long as possible. We'll see how long that is. But, and in the meantime, there are programs that are supporting Webb science that really demonstrate the need for precision UV, an obstacle observations to continue for years to come. And so I just called out two examples here. Programs led by Alison Youngblood and then one by Hannah Diamond-Lowe who are looking at, for example, exoplanet host stars in the UV to assess atmosphere formation, retention, stability, and chemistry. And so it's really important to get this data, to feed back into understanding what the results are from Webb. And so we could flip it around and say whatever we learned from Webb might demonstrate even further how much more UV data we need right from a future flagship mission. So we have a lot to learn, but I think we have time to plan. So with that, that was just my one quick slide on that note. But otherwise I just wanted to call out recent and upcoming events. There's a lot of great resources. I mentioned the transit ERS webpage plus space telescope site also has J webinars that were recorded and have material including one on time series observations led by Nestor Espinoza and Sarah Kendrew. And then there's the James Webb Town Hall for, it's supposed to be part of WAS, that's been postponed to January 28th. So stay tuned for details on that. And I think with that, I'll just end by saying, well we had a nominal launch and midcourse correction burdens to get us out on our way to L2, and it's been reported unofficially that Webb's basically now fuel limited with likely over 20 years of fuel, but there is assessment coming out and there will be future information on this coming out. So definitely keep an eye on the blog posts, the websites on the lower right, so that you can get regular updates. They should be coming out at least weekly. Now that all the major deployments are done, we're still gonna have updates on all the things happening. And then I just wanted to say, thank you to the countless number of people who've worked on this project over the decades, as well as those who worked over the holidays and during a pandemic to make the launch and deployments such a success, So go Webb and I'm happy to take any questions if there's time. Thank you.

- Yeah, thank you very much. These are really exciting news and there are questions in fact. For the first one is, "When can we expect to hear about JWST cycle "to call for proposals?"

- Ah, yes. I don't think an official date has been announced, but it's supposed to normally be L+13 months. I can't remember if that's a deadline or the call coming out. Someone from Space Telescopes probably online can correct me, but I think we'll hear, hopefully see an update, but it's sometime this fall at the earliest. I'll just say that, yeah.

- Yeah, as far as I remember, L+13 months is the deadline, but maybe I don't know. So second question, "Will the JWST exoplanet "commissioning data be made publicly available "and if so, when?"

- Oh yeah, that's another great question. I believe the commissioning data will be public at some point, but I think the timeline for that is not a part of an official plan. So it's like the science data will be made public, basically ASAP if it doesn't have exclusive access period, the commission data, I don't know that there's an official plan for that, but I think the intention is that it will go public just at some point. Sorry, I don't have a better answer.

- Okay, thank you. And then, as you can all see, I think at this point that there is another question, "Will the community be able to find out which targets "will be Early Release observations "when will they occur and when they will be released?"

- Yeah, so I'll be honest. I don't even know what targets are part of the Early Release observations, but I know that there will be a press release basically after commissioning to release these first images, science images. It's still an open question as to whether there will be imaging data released before that, that's engineering data, like kind of like first light or when we're focusing stars and all that, that is TBD. But if nothing else, there's definitely going to be a release after the commissioning period. So like end of June, let's say early July, if the commissioning, stays on on track as it should.

- Okay, so thank you very much. And with this, I think we answered all the questions except the first one, which I think requires a bit more discussion and probably is better suited another session, any way they will be posted also on Slack so hopefully Gary Blackwood or Eric Mamajek will answer that question. With that, we finish the first session today. We will resume at 2:00 PM Eastern time, but before finishing, let me ask everyone to unmute and really thank and applaud all the speakers in this session, because these were really very important and exciting talks. Thank you.

- [Abi] Great job everyone. Thank you.

- [Andrew] Thank you Ilaria.
