 This is courtesy of the stuffily bureaucratic blimps—intelligent extraterrestrials living in the turbulence of Jupiter's upper atmosphere whose advanced gravity technology allows them to alter the orbital plane of the planet's moons and thereby avoid the type of cometary impact which, obliquely, precipitated their exodus from an unknown 'Firsthome' to Jupiter itself.Left with twelve years until impact and now convinced of the wheelers' authenticity, Earth's governmental authorities speed a mission to the Jovian satellites in hopes of contacting the as yet unseen alien lifeforms.Dunsmoore is selected to lead the group, with the assumption that his experience with decrypting anthropological artefacts on earth will aid in establishing communiqué with the Jovians.
