More 700,000 people have sent their name to NASA. Engineers will use an electron
to write them on a
silicon microchip. Each line of
is less than 1/1000th of the
of a human hair. NASA said: "The
and names will be like a
in a bottle as they make about 50 close flybys of [Europa's] ocean world." The Europa Clipper spacecraft will gather
on Europa's atmosphere, icy
and ocean. NASA said: "Europa is such a promising place to better understand the astro-
potential for
worlds beyond Earth."
