NASA NAMES TEAM TO STUDY RETURN TRIP TO MARS
NASA Administrator Daniel S. Goldin today announced the
establishment of a study team at NASA's Jet Propulsion Laboratory
(JPL), Pasadena, Calif., to explore possibilities for a return
mission to Mars to recover some of the scientific objectives of
the Mars Observer mission, if communications with that spacecraft
cannot be reestablished.
The study team, led by Dr. Charles Elachi, Assistant Laboratory
Director at JPL, will look at a variety of low-cost spacecraft,
instrument and launch options, with the objective of returning to
Mars in 1994 or 1996.
The team will review available spacecraft and instrument options
from industry and government, including Mars Observer spares and
possible international contributions.  The team is expected to
present potential mission options to NASA within the next 2 months.
Members of the study team currently include:
Arden Albee     California Institute of Technology, Pasadena
Carl Sagan      Cornell University, Ithaca, N.Y.
Bruce Murray    California Institute of Technology, Pasadena
John Casani     JPL
