SPECIAL NOTE FOR GRADE SCHOOL TEACHERS: THIS IS A GREAT TEACHING OPPORTUNITY TO GET YOUR STUDENTS INVOLVED WITH THE NASA SPACE PROGRAM. Five weeks remain for you to add your name to a microchip that will ride aboard the Europa Clipper spacecraft as it explores Jupiter’s moon Europa. It’s not every day that members of the public have the chance to send their names into deep space -- all the way to Jupiter and its moon Europa. But with NASA’s 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’s “Message in a Bottle” campaign is only five weeks away. The campaign closes at 11:59 PM EST, December 31, 2023.
