Division of the Hipparcos satellite observation time into two 1.25 yr periods separated by a 5 yr shutdown is proposed. The planned 2.5 yr continuous program gives proper motions comparable to ground based observations. A long-life program gives proper motions three to four times more accurately. Parallax effects could be better separated from proper motion effects, with much lower systematic errors. Tie-in of asteroid orbits, and of the planetary system, to the Hipparcos inertial system would be improved. Reliability of binary star orbits, and the possibility of detecting planetary systems would be much higher. Implementation is feasible, using a slightly modified design, since components are inactive for most of the time.
