NASA Ralph, one of the best-trained scientific instruments, is expected to explore the Jupiter Trojan horse's asteroids on an Lucy spacecraft in 2021, said the US Space Agency.
Ralph has made many discoveries since his first launch on the New Horizons spacecraft in 2006. Thanks to the name and not the acronym, Ralph makes it possible to study the composition and atmosphere of the sky.
NASA's Spacecraft Notice In 2021, the Lucas spacecraft will host Ralph's close-knit twin, called L & # 39; Ralph (Lucy Ralph), to investigate the Jupiter Trojan horse's asteroids, which are the remnants of the days of the solar system. On Wednesday
The L & # 39; Ralph tool kit will explore this diverse range of bodies. Lucia will fly with six Trojans and one major belt asteroid, more than any other previous asteroid mission.
L & # 39; Ralph will discover Trojan's asteroid chemical fingerprints, said in a statement. L & # 39; Ralph allows scientists to interpret the data provided by the reflected light of the sun, which is a fingerprint of various elements and compounds.
These data can give insight into how organic molecules are formed in primitive bodies, which could also lead to the emergence of life on Earth.
L & # 39; Ralpham must have many options for a small, lightweight body structure so that the spacecraft is efficient and the mission is productive.
Its suite of tools includes a multifunctional visible image camera (MVIC) and a Linear Etalon Imaging Spectral Array (LEISA), both powered by the same optics, which means that both visible and infrared wavelengths can be observed by Ralph.
These two options are what make Ralph and his cousin L & # 39; Ralph so special, according to L & # 39; Ralph instrumental researcher Dennis Reuter.
"Most instruments can display visible or infrared wavelengths, but L & # 39; Ralph can do both," Reuters said.
Lucia L & # 39; Ralph has improved technology compared to Ralph flying with New Horizons. It can detect a wider spectrum of electromagnetic radiation, it has a moving mirror that reflects the light of L & # 39; Ralph, rather than requiring the entire spacecraft to move.
Ralf Infrared Detectors are 2,000 pixels square compared to New Horizons Ralph 256 by 256, allowing images with more details.
