NASA has officially invited people from all over the world to register their names in the “Messages to Bennu” program. All those names will be recorded on a microchip that will travel aboard the OSIRIS-REx (Origins Spectral Interpretation Resource Identification Security Regolith Explorer) spacecraft, which is expected to start its mission in September 2016 for the asteroid 101955 Bennu to collect a sample to bring back to Earth.
