First light: Hera resolves two asteroids instead of one

The European Space Agency's Hera spacecraft for planetary defense has resolved its two target asteroids separately for the first time, revealing the binary nature of the Didymos system, currently some 197 million km (122 ...

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 ...
