...onto the spacecraft. There, an instrument will heat the soil in tiny ovens, checking the resulting vapors for water and carbon compounds. An on-board chemistry lab with dual microscopes will add water to the sample and analyze the spectral and electrochemical results to check acidity, salt levels, and ion concentrations...
...world scenarios are not new. Wagner filed a similar complaint in 1999 and 2000 to prevent the Relativistic Heavy Ion Collider at Brookhaven National Laboratory from going online. The collider, which has been functional since 2000, has yet to produce a black hole...
...addition to collecting particles for analysis in an ion and neutral mass spectrometer, and a cosmic dust analyzer, Cassini will photograph yet unseen parts near the moon's south pole. It will also use infrared technology to create a comprehensive map of surface temperatures at the south pole. Warmer temperatures increase the likelihood that there is water in liquid form on the small moon...
...come complete with a dedicated spa butler, treatment room, infrared sauna, rainforest shower and organic minibar. They're also the setting for the 14-day Ultimate Fitness Program for Two - a tailor-made overhaul that includes 26 yoga, pilates or fitness classes, four exfoliations, 18 sports massages, three silver-ion facials and daily herbal remedies. The package costs a total of $59,400 - a sum that might have given you a heart attack, were you not in such tip-top shape upon billing...
...matter what the ship eventually reveals about Vesta and Ceres, NASA believes a successful mission could help establish ion technology as the propulsion system of choice for any mission in which the need for fuel is high and the need for speed is low. "Because of ion propulsion," says Rayman, "Dawn can explore the last unexplored worlds in the solar system." Not bad on a single small tank...
