Six weeks remain for you to add your name to a microchip that will ride aboard the spacecraft as it explores Jupiter\u2019s moon Europa.<\/em><\/p>\n It\u2019s not every day that members of the public have the chance to send their names into deep space beyond Mars, all the way to Jupiter and its moon Europa. But with NASA\u2019s Europa Clipper, you have that opportunity: Names will ride aboard the spacecraft as it journeys 1.8 billion miles (2.6 billion kilometers) to this icy moon, where an ocean hides beneath a frozen outer shell. The deadline to join the mission\u2019s \u201cMessage in a Bottle\u201d campaign is only six weeks away. The campaign closes at 11:59 p.m. EST, Dec. 31, 2023.<\/p>\n So far, about 700,000 names have been submitted. Once all the names have been gathered, technicians in the Microdevices Laboratory at NASA\u2019s Jet Propulsion Laboratory in Southern California will use an electron beam to stencil them onto a dime-size silicon microchip. Each line of text is smaller than 1\/1000th the width of a human hair (75 nanometers).<\/p>\n \n
