This is where the OWLS suite comes into play. The new device is designed to ingest liquid samples that are then analyzed by eight automated instruments that would require the work of several dozen people in a lab on Earth. The suite includes a front-end extractor that uses pressure and temperature to extract various solid and liquid samples.
The ELVIS subsystem then relies on machine learning algorithms to detect “lifelike” movement and objects illuminated by fluorescent molecules, whether this is naturally occurring or the result of dyes binding to certain parts of cells. Developed by scientists at NASA JPL and Portland State University, this system will be the first in space capable of imaging cells.

NASA seeks new rockets for hurricane satellite launches after Astra failuresElizabeth Howell, Ph.D., is a staff writer in the spaceflight channel since 2022. She was contributing writer for Space.com for 10 years before that, since 2012. As a proud Trekkie and Canadian, she also tackles topics like diversity, science fiction, astronomy and gaming to help others explore the universe. Elizabeth's on-site reporting includes two human spaceflight launches from Kazakhstan, three space shuttle missions in Florida, and embedded reporting from a simulated Mars mission in Utah. She holds a Ph.D. and M.Sc. in Space Studies from the University of North Dakota, and a Bachelor of Journalism from Canada's Carleton University. Elizabeth is also a post-secondary instructor in communications and science since 2015. Her latest book, Leadership Moments from NASA, is co-written with astronaut Dave Williams. Elizabeth first got interested in space after watching the movie Apollo 13 in 1996, and still wants to be an astronaut someday.
