Officials also will provide details on the Phoenix landing site. The briefing will take place in the NASA Headquarters' James E. Webb Auditorium, 300 E St., S.W., Washington. It will be carried live on NASA Television and on the Web. Phoenix is expected to conduct a three-month mission studying a northern arctic site on the Red Planet. Phoenix will dig down to an ice-rich layer expected to lie within arm's reach of the surface of Mars. It will analyze the water and soil for evidence about climate cycles and investigate if the environment there has ever been favorable for microbial life.
