Spaceflight Now: Space Station/STS-98

STS-98 Entry Timeline
Updated: February 19, 2001

The deorbit timeline on any space shuttle mission begins four hours before the rocket firing that drops the ship out of orbit. This is known as "TIG (time of ignition) minus four hours." The actual start of the deorbit timeline, however, can vary by several minutes depending on the crew's schedule. The start of deorbit operations as listed in the chart below may by out of synch with NASA's official timeline by a few minutes either way.
