NASA's Ralph to explore Jupiter's Trojan asteroids in 2021
NASA's space explorer Ralph will explore Jupiter's Trojan asteroids aboard the Lucy spacecraft in 2021, the US space agency has said. The spacecraft will carry a near-twin of Ralph, called L'Ralph, to investigate Jupiter's Trojan asteroids, which are remnants from the early days of the solar system. Ralph was first launched aboard the New Horizons spacecraft in 2006.
