A new study explores the potential of nuclear fission-powered propulsion for advanced deep space exploration. Specifically, it looks at the way this technology could enable exploration to the outer ...

Deep space travel has a biology problem. Human bodies are built for a narrow band of temperatures, gravity and radiation, yet any realistic journey to Mars or beyond would subject astronauts to months ...

When scientists first sent microscopic worms into orbit in 2018, they hoped to answer a question that has shaped every discussion about long missions. What really happens to your body when gravity no ...

KENNEDY SPACE CENTER, Fla. — The Artemis II mission will not only test the Orion spacecraft, but it will also evaluate how modern deep-space travel affects the human body. The mission is expected to ...

CAPE CANAVERAL, Fla. – Space travel is far from one-size-fits-all: Missions to different destinations—whether low Earth orbit, the Moon, or Mars—present unique challenges, especially when it comes to ...

The four astronauts who make up NASA’s Artemis II crew are the first to embark on a mission to the moon in over half a century. But once they complete their flyby, they’ll also earn the rare ...

AUSTIN (KXAN) — Deep beneath the surface in a quiet corner of the basement of the Physics, Math and Astronomy building of the University of Texas at Austin, lasers blast electronics with simulated ...

NASA's Artemis I mission takes a selfie of the Orion capsule on its way to the moon. Travel beyond the Earth's atmosphere and magnetic fields involves exposure to high levels of radiation from the sun ...

NASA’s Artemis II crew fired the Orion spacecraft’s main engine, committing the mission to a trajectory toward the moon just one day after launching into deep space. The translunar injection burn, ...
