TMO Background Mode Interview with Planetary Scientist Dr. Alan Stern

· · Background Mode Podcast

Dr. Alan Stern on Background Mode.

Dr. Alan Stern is a planetary scientist with the Southwest Research Institute. He’s also the co-founder and chief scientist of World View, working with high altitude balloon research. He is perhaps most famous as the principle investigator for NASA’s New Horizons mission to Pluto. Way back in grade school, Alan was interested in space exploration and wanted to be a part of the Star Trek future. He received his Ph.D. in planetary science from the University of Colorado, and that launched his life-long interest in Kuiper Belt Objects and the Oort Cloud. He’s a licensed pilot, was selected by NASA as a Payload Specialist, and has flown research missions in high performance jet aircraft. We talked about his career, the New Horizons mission design, Pluto discoveries (and planetary classification) and his latest research.

Artist Uses iPhone ARKit to Visualize Sound in 3D Space

· · Cool Stuff Found

Zach Lieberman is an artist who is exploring how to create art using iPhone ARKit. His latest creation? Recording audio in space. In the demo video, Zach makes sounds like “woosh, psh, ah, click.” After each sound, a white blob bursts into the air, and as Zach walks backward, each blob is linked to the other blobs like a audio timeline. When he walks forward again through the trail, you hear each sound playing in reverse. Zach, who helps run the School For Poetic Computation in New York City, built the demo using Simultaneous Localization And Mapping (SLAM). It uses the iPhone’s sensors and camera to create a low-res map of the room. The app records sound with the microphone, processes and visualizes it, and then maps each sound blob to a location within the room.
