On Launch Pad 17-B at Cape Canaveral Air Force Station in Florida, workers check the lines attached to the lower end of the United Launch Alliance Delta II rocket before it is lifted into the mobile service tower. 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.

RS-27ARS-27A je raketový motor střední velikosti vyvinutý společností Rocketdyne, jako pohon pro první stupeň raket Delta II a Delta III. Vývoj začal v roce 1987 a první let se konal roku 1989. Jako palivo slouží směs RP-1 a tekutého kyslíku. Využívá otevřeného cyklu, tzn. část paliva je spálena a takto vzniklá energie je využita pro pohon palivového čerpadla. .. pokračovat ve čtení
