NASA announced May 26, it has selected nine science instruments for a mission to Jupiter’s moon Europa to investigate whether the icy moon has conditions suitable for life. The instruments, targeted for launch aboard a robotic probe in the 2020s, include cameras and spectrometers to collect high-resolution imagery; an ice penetrating radar to measure surface thickness and look for subsurface lakes; and a magnetometer to measure the strength and direction of the moon’s magnetic field, and allow scientists to determine the depth and salinity of the moon’s ocean.
