Mission Highlights

STS-42 Mission Patch The primary payload was the International Microgravity Laboratory-1 (IML-1), making its first flight and using the pressurized Spacelab module. The International crew was divided into two teams for around-the-clock research on the human nervous system's adaptation to low gravity and the effects of microgravity on other life forms such as shrimp eggs, lentil seedlings, fruit fly eggs, and bacteria. Materials processing experiments were also conducted, including crystal growth from variety of substances such as enzymes, mercury iodide and a virus. On flight day six, mission managers concluded enough onboard consumables remained to extend the mission one day to continue science experiments.

Secondary payloads were: 12 Get Away Special (GAS) canisters attached to a GAS Bridge Assembly in the cargo bay and containing a variety of U.S. and international experiments.

In middeck: Gelation of Sols: Applied Microgravity Research-1 (GOSAMR-1); IMAX camera; Investigations into Polymer Membrane Processing (IPMP); Radiation Monitoring Experiment III (RME III); and two Shuttle Student Involvement Program (SSIP) experiments.
