Using eyedrops in space—wearable patch offers a new approach

Applying eyedrops is difficult in space, where there is almost no gravity. A KAIST research team has developed a wearable patch that delivers eyedrops to the eye without relying on gravity. The research team was led by Professor ...

Lucy mission marks 5 years of discoveries

On Oct. 16, 2021, NASA's Lucy spacecraft began its journey to the never-before-explored Jupiter Trojan asteroids with an early morning launch. Now less than a year away from the first-ever close-up of a Trojan, the Southwest ...

Japan to launch historic round-trip mission to Mars moon

Japanese scientists are readying a mission to Mars' moons to retrieve samples that could help unlock the origins of the solar system and life on Earth, in what aims to be the first round trip to the Martian region.

NASA develops batteries to power humanity's return to moon

If you've ever had your car start sluggishly, or not at all, on a particularly frigid winter morning, you know standard batteries do not like extreme cold. That's why NASA researchers are working to develop a battery that ...
