thank you thank you for coming to my talk I work on a project called opus it's a search interface that for that people use to find data and images from NASA space probe missions to the outer solar system it's built on Jango and I'm going to talk
a little bit about why we built it and some of the ways people are using it and I'll demo it as well so I work at SETI Institute in Mountain View California a study stands for search for extraterrestrial intelligence and it started in nineteen eighty-four
as a nasa project to use radio observatories to listen for signals from other star systems that might indicate signs of intelligent life and so today 30 years later study runs its own up it runs its own radio observatory and the SETI project is still going
strong but it's also a larger research center where it's the base of operations for over 60 scientists and their students and staff who study many areas of planetary science such as planetary geology asteroid research planetary dynamics exoplanets
so basically anything related to the study of life and habitability in the universe so a group at SETI is a nasa-funded data archive and our scientific leadership are experts in planetary ring moon systems so many people are aware that saturn has these epic
beautiful rings but a lot of people don't realize that Jupiter Neptune and Uranus actually have rails as well and these are some pictures of them and so we at the Rings node archive data from missions to these planets and we support researchers in this
field we built opus in fine NASA tradition we gave it an acronym opus stands for outer planets unified search and idea is that when you've I'm sorry when you've we brought seven missions into one civil interface so like we've unified them so
I'll jump right into demoing it for you so this is the landing page and ironically let's sort of my least favorite page of the interface because it's just a little bit complicated when we first land on it we serve primarily the scientific research
community and it has a lot of features and options and it has a lot of specialized features so it can be rather complicated my sort of bad joke is that it looks like a DMV form but the idea is this you start with a lot of results that you can access our entire
entire database so that blue bar at the top there's a number if you can see that that's telling you that there are 1.2 million results that you can access right now and that is a count of everything in the database so for this tool we archive the complete
set of remote sensing observations for several NASA missions both Voyager probes Cassini Galileo new horizons and there's some Hubble data in here as well and so the idea is that you want to narrow down your results can't to find the data that you're
looking for or what you want to learn about and the interface gives you feedback as you sort of drill down into the data and on the left side there's this monster list of parameters and if you click one of those it brings in a search widget there are now
two search widgets showing by default in the center so to bring in a search widget based on any number of parameters and you can use those to constrain your search so so i'll show you what i mean i'll go ahead and click Jupiter and the first thing
you might notice is that a list opens below where i clicked so that is actually a list of Jupiter's moons so when you click one of the planets you get a list of its targets or its moons or really features will open and it lets you sort of drill down further
and the other thing that happened is that the number in the top got a lot smaller because you're basically saying show me only results tagged Jupiter and so clicking browse results to see what we get and you get this gallery of space images that is forever
infinite scrolling so the default ordering of this interface is ascending time so what we're actually seeing here is are the earliest observations in our database and this is Voyager 1 as it first opens its camera shutter and images the planet Voyager
on its approach to Voyager so the Voyager mission is actually two spacecraft they're identical they were launched a few months apart in the late 70s and they both had an original mission of just going to Jupiter and Saturn but they've both extended
