COLOR 20 JUNE - 7 JULY 1996 STS078-368-022 JOHNSON SPACE CENTER, HOUSTON, TEXAS STS-78 ONBOARD VIEW --- Astronauts Susan J. Helms, payload commander, and Terence T. (Tom) Henricks, mission commander, prepare a sample cartridge containing semiconductor crystals for Spacelab research. The crystals were later placed in the Advanced Gradient Heating Furnace (AGHF) in the Life and Microgravity Spacelab (LMS-1) Science Module. The AGHF is designed for directional solidification of the crystals in the sample cartridges. The microgravity of space allows the crystals to grow in a perfect state that can not be accomplished in Earths gravity.
