Team designing instrument to explore rare metal asteroid
A team of US-based researchers is designing a gamma-ray spectrometer to explore a rare, metal asteroid 'Psyche' between Mars and Jupiter. The asteroid's composition would be studied based on its gamma-ray signatures. Researchers are studying an iron-nickel meteorite believed to have similar compositions, that fell to Earth in 1922. NASA would be launching the instrument by 2022 to explore Psyche.
