More than 700,000 names have
been submitted to NASA. Engineers will use an
beam to
them onto a tiny silicon microchip. NASA said: "Each line of
is smaller than 1/1000th the
of a human hair (75 nanometres)." It added: "Riding on the exterior of the spacecraft, the poem and names will be like a message in a
as they make about 50 close
of [Europa's] ocean world." Europa is one of Jupiter's 95
recognized moons. The Europa Clipper will gather

worlds beyond Earth."
