The mission will not land on the moon, but it is intended to go into orbit around it. The robotic mission is to collect detailed information about the moon’s thin atmosphere. Sometimes thought to be nonexistent, the lunar atmosphere has been described as extremely tenuous and fragile, but present. According to the space agency, the launch will record many firsts. One will be the first launch beyond Earth orbit from the Virginia facility. Cool.
