Floating in near-weightless conditions can be disorienting for even the most experienced astronauts. Male reproductive cells—sperm—also seem to get confused in simulated microgravity, which has implications for human reproduction in space, according to a study published March 26 in the journal Communications Biology.

NASA launched the Artemis II mission, which will carry humans to the moon for the first time since 1972.

Researchers put human sperm into a microgravity simulation chamber designed to mimic the female reproductive tract and tested the swimmers’ ability to navigate. Under microgravity conditions, the sperm saw “impaired directional navigation”—in other words, they got lost—more often than under typical gravity conditions on Earth.

Four astronauts have begun a ten-day mission in which they’ll loop around the moon, laying the groundwork to put humans on the lunar surface as early as 2028

Because there's more to extra-terrestrial life than humans with prosthetics stuck to their foreheads.

Going to space is harsh on the human body, and as a new study from our research team finds, the brain shifts upward and backward and deforms inside the skull after spaceflight. Vast has raised $500 million in new funding, which the California startup will put toward its goal of getting private space stations up and running in Earth orbit.

NASA's Artemis II mission is set to launch Wednesday, sending four astronauts on a 10-day journey around the moon and back to Earth. While the mission will not include a landing, it marks a major step forward in returning humans to deep space.

Having babies born in space could produce an interesting conundrum as shown by research with one particular creature.

In an astonishing twist of our technological progress, humans have inadvertently created a space barrier around Earth. This article delves into the nature of this barrier, its formation and its potential impacts on Earth and space exploration. The ...

NASA took a giant leap toward returning humans to the moon Wednesday evening with the successful launch of the Artemis II mission. From the Johnson Space Center campus in Houston, employees and
