Shuttle Torque

CAPE CANAVERAL., Ha-The shuttle Columbia testing a fuel saving maneuver 186 miles above Earth, experienced "unexplained torque" yesterday that caused a series of harmless pitch and roll movements. The phenomenon went away as mysteriously as it began and officials were curious but not worried.

Otherwise Day Two of Flight Four was routine as astronauts Ken Mattingly and Henry Hartsfield went about their business, conducting commercial and military experiments and checking out Columbia's systems.

The crew's health is excellent the guys are really jubilant," said Flight Director Harold Draughon. "They are up and around with no problem at all and doing more than we ask of them."

On Earth NASA directed recovery ships to mark the spot in the Atlanta Ocean where the shuttle's twin rocket boosters sank after launch on Sunday.
