KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base, Calif., the Pegasus launch vehicle is moved toward its hangar. The Pegasus will carry the SciSat-1 spacecraft in a 400-mile-high polar orbit to investigate processes that control the distribution of ozone in the upper atmosphere. The scientific mission of SciSat-1 is to measure and understand the chemical processes that control the distribution of ozone in the Earth’s atmosphere, particularly at high altitudes. The data from the satellite will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policymakers assess existing environmental policy and develop protective measures for improving the health of our atmosphere, preventing further ozone depletion. The mission is designed to last two years.

KENNEDY SPACE CENTER, FLA. -- In the mobile service tower on Pad 17-B at Cape Canaveral Air Force Station, workers observe and help guide the second half of the fairing toward the THEMIS spacecraft. The first half has already been put in place. The fairing is a molded structure that fits flush with the outside surface of the Delta II upper stage booster and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch and ascent. THEMIS is an acronym for Time History of Events and Macroscale Interactions during Substorms. THEMIS consists of five identical probes that will track violent, colorful eruptions near the North Pole. This will be the largest number of scientific satellites NASA ever launched into orbit aboard a single rocket. The THEMIS mission aims to unravel the tantalizing mystery behind auroral substorms, an avalanche of magnetic energy powered by the solar wind that intensifies the northern and southern lights. The mission will investigate what causes auroras in the Earth’s atmosphere to dramatically change from slowly shimmering waves of light to wildly shifting streaks of bright color. Launch of THEMIS is scheduled for Feb. 15 aboard a Delta II rocket, with the launch service being conducted by the United Launch Alliance. Photo credit: NASA/George Shelton KSC-07pd0343

KENNEDY SPACE CENTER, FLA. -- The first stage of a United Launch Alliance Delta II rocket is on its way to Launch Pad 17-B on Cape Canaveral Air Force Station in Florida. The rocket is the launch vehicle for the THEMIS spacecraft, consisting of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. After the first stage is in the mobile service tower on the pad, nine solid rocket boosters will be placed around the base of the first stage and attached in sets of three. THEMIS is scheduled to launch aboard the Delta II at 6:07 p.m. EST on Feb. 15. Photo credit: NASA/George Shelton KSC-07pd0022
