Space Apps Challenge 2018

iET is a mixed reality immersive experience of known exoplanets with smart filtering for locating earth-like exoplanets. This app would provide context + presence of the exoplanets + star systems, giving an alternate way for scientists to look at the data – from scatterplots to immersive presence with the planets.

Describing exoplanets as worlds suggest that these are objects that can be not only perceived but also experienced. With enough information, one can imagine being on the surface of one of these worlds.– Lisa Messeri, Placing Outer Space, p. 113

iET was inspired by the work of Lisa Messeri – anthropologist at Yale University – who believes that the key to truly understanding all the newly discovered exoplanets is creating a sense of presence. Mixed reality/VR creates presence like no other technology. We chose this medium because it provides huge potential in giving scientists a way to literally be with the data of these unknown worlds – by literally bringing them into the presence of these planets. iET is meant to help scientists visualize what these new worlds might be like outside of scatterplots and data points – to make distant exoplanets “more like intimate, recognizable worlds” (Messeri).

One of the main goals of iET is to help visually identify data leading to habitable planets. Throughout iET development, we’ve prioritized showing data that expressed the potential of habitability for each exoplanets - such as a planet’s distance from the sun, it’s place in the habitable zone and what elements have been discovered.

DATA + RESOURCES: The data we used to create this app primarily came from NASA’s Exoplanet Archive. We also dipped into the Exoplanet Encyclopedia (exoplante.eu) to access elemental data for each of the planets. This collection of data was the foundation for what was used to program the creation of the planets and stars you see in the current iteration of the app from work done this weekend.

PROJECT CHALLENGES:

• COMPLEXITY OF DATA + UNDERSTANDING THE SCIENCE + MATH –
• MIXED REALITY TOOLKIT - After much discussion, we chose to use the new Mixed Reality Toolkit for the app build. This would allow us to create one build that can be experienced across various mixed reality + VR devices – a revolutionary potential in immersive technology. We received early access to this new tool before it’s official release, along with direct support from Microsoft to use it for this project. We were excited by the Mixed Reality Toolkit as it would allow our team – who were from 3 different cities with different devices in each location – to test the evolving app across multiple devices. Plus, we believed an app built with this technology would be more accessible to scientists globally who may all have access to various different headsets. In theory, by building it with the Mixed Reality toolkit, any scientist could experience the app on any headset – Hololens, Oculus Rift, Vive, etc. Unfortunately, the learning curve for integrating this toolkit – along with working out the bugs with Microsoft - was steep + the challenges working with this new technology slowed us down on Saturday as our team spent a lot of time in discussion with Mircrosoft. Unfortunately, this ate into our dev time resulting in not getting as far as we were hoping to by today’s end of challenge.
• MULTIPLE LOCATIONS + TIME ZONES - Another challenge we were faced with was that our team was scattered across 3 locations – Los Angeles, Canada + Hawaii. The advantage of this was that – due to differing timezones - the project going 24/7. The disadvantage of this, was that our team could not take advantage of sharing in moment-by-moment collaboration + inspiration as problems and solutions emerged.

REALIZING THE COMPLETE VISION

• BUILDING OUT THE STAR SYSTEMS INCLUDING OUR OWN WITH ACCURATE ORBITAL MECHANICS – We have currently been able to realize all the exoplanet’s stars and the next step would be to realize all the star systems w/ exoplanets.
• REFINE INTERFACE + UX WITH INPUT FROM SCIENTISTS – We would like to work with scientists to explore the interactivity + data to build a tool that will be most impactful for the community.
• CREATE EXOPLANET CATEGORIZATION + REFINE VISUALS WITH SCIENTISTS - With input from scientists, we’d like to determine the best exoplanet categorization and to more closely visually match the data/science we have for each individual planet + star. For example, we’d like to utilize what we know about geometric albedos to inform how each exoplanet may actually look (Madden & Kaltenegger, 2018).
• SHARED VIEWING EXPERIENCES FOR COLLABORATION – Ultimately, this app would have a view sharing component allowing scientists to collaborate with other scientists around the world.
