NASA's Ralph to Explore Jupiter’s Trojan Asteroids in 2021

Washington: NASA’s Ralph, one of the most well-traveled scientific instrument, is set to explore Jupiter’s Trojan asteroids aboard the Lucy spacecraft in 2021, the US space agency said. Ralph has made many discoveries since it first launched aboard the New Horizons spacecraft in 2006. Given a name and not an acronym, Ralph enables the study of the composition and atmospheres of celestial objects. In 2021, the Lucy spacecraft will carry a near-twin of Ralph, called L’Ralph (“Lucy Ralph”), to investigate Jupiter’s Trojan asteroids, which are remnants from the early days of the solar system, NASA said in a statement on Wednesday.
