The Canadian Space Agency’s Scientific Satellite
Atmospheric Chemistry Experiment (SCISAT-1) is scheduled to
launch on Tuesday, August 12, between 10:05 and
11:02 p.m. EDT.

An L-1011 jet aircraft departing from Vandenberg Air Force
Base (VAFB), Calif., will carry the Pegasus XL vehicle that
will launch SCISAT-1. The L-1011 will drop the Pegasus, and
its 330-pound spacecraft, over the Pacific Ocean at
approximately 10:10 p.m. EDT. The SCISAT-1 mission will
provide scientists with improved measurements of the chemical
processes that control the distribution of ozone in Earth’s

The pre-launch press conference is at the NASA Resident Office
