Swarm of Tiny Swimming Robots Could Look for Life on Distant Worlds

In the Sensing With Independent Micro-Swimmers (SWIM) concept, illustrated here, dozens of small robots would descend through the icy shell of a distant moon via a cryobot – depicted at left – to the ocean below.

A concept in development at NASA’s Jet Propulsion Laboratory would allow potential planetary missions to chase interesting clues in subsurface oceans.

PASADENA, Calif. (NASA PR) — Someday, a swarm of cellphone-size robots could whisk through the water beneath the miles-thick icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking for signs of alien life. Packed inside a narrow ice-melting probe that would tunnel through the frozen crust, the tiny robots would be released underwater, swimming far from their mothercraft to take the measure of a new world.

NASA Selects Futuristic Space Technology Concepts for Early Study

WASHINGTON (NASA PR) — An astronaut steps into a body scanner and, hours later, walks on Mars in a custom-made spacesuit, breathing oxygen that was extracted from Mars’ carbon dioxide-rich atmosphere. On Venus, an inflatable bird-like drone swoops through the sky, studying the planet’s atmosphere and weather patterns. Ideas like these are currently science fiction, but they could one day become reality, thanks to a new round of grants awarded by NASA.

Visionary Tech Concepts Could Pioneer the Future in Space

WASHINGTON (NASA PR) — NASA missions make it seem like the future is now – rovers exploring Mars with cutting-edge gadgets, a spacecraft venturing home with an asteroid sample, and a complex space telescope peering at the early universe. So, what’s the next big thing? What might space missions in 2050 and beyond set out to discover? 

One small NASA program aims to see what could be possible. The NASA Innovative Advanced Concepts (NIAC) program, part of the agency’s Space Technology Mission Directorate, funds early-stage research into sci-fi sounding, futuristic technology concepts. The goal is to find what might work,  what might not, and what exciting new ideas researchers may come up with along the way

SwRI Researcher Theorizes Worlds with Underground Oceans May be More Conducive to Life than Worlds with Surface Oceans like Earth

Interior water ocean worlds like Saturn’s moon, Enceladus, are prevalent throughout the universe. New research from Southwest Research Institute suggests that layers of rock and ice may shield life within such oceans, protecting it from impacts, radiation and other hazards and concealing it from detection. Layers of rock and ice may therefore shield and protect life residing in them, and also sequester them from threats and detection.

SAN ANTONIO, Texas, March 16, 2021 (Southwest Research Institute PR) — One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, like Europa, Titan and Enceladus, and distant planets like Pluto.
