NASA is building a satellite that will explore moon oceans. The technology will be able to survey planets and also send instruments, unlike current technology that can either do one or the other. The first destination may be Jupiter’s moon, which researchers speculate holds water. The satellite, which will be the size of a milk cartoon, will be able to dispense fingernail-sized chips into the atmosphere to explore. When the chips are released, they float down to gather measurements, then send the information back to the mothership. NASA will partner with Draper Laboratories to design and prototype the satellite.
