The Neurolab payload for STS-90, scheduled to launch aboard the Shuttle Columbia from Kennedy Space Center (KSC) on April 2, 1998, is moved to its workstand in the Operations and Checkout Building at KSC. Investigations during the Neurolab mission will focus on the effects of microgravity on the nervous system. Specifically, experiments will study the adaptation of the vestibular system, the central nervous system, and the pathways that control the ability to sense location in the absence of gravity, as well as the effect of microgravity on a developing nervous system. The crew of STS-90 will include Commander Richard Searfoss, Pilot Scott Altman, Mission Specialists Richard Linnehan, Dafydd (Dave) Williams, M.D., and Kathryn (Kay) Hire, and Payload Specialists Jay Buckey, M.D., and James Pawelczyk, Ph.D KSC-97PC1713

KENNEDY SPACE CENTER, FLA. -- An oyster toadfish (Opsanus tau), like those that are part of the Neurolab payload on Space Shuttle Mission STS-90, is shown in its holding tank in the Space Station Processing Facility. Each fish is between eight and 14 inches long. Toadfish live in an estuarine environment and are native to areas along the Northeast coast of the United States. Since they are bottom dwellers that live in cracks and crevices, a tube is provided in its tank to give it a place to retreat and hide. Investigations during the Neurolab mission will focus on the effects of microgravity on the nervous system. This fish is an excellent model for looking at vestibular function because the architecture of its inner and middle ear are similar to those of mammals with respect to the vestibular apparatus. The crew of STS-90, slated for launch April 16 at 2:19 p.m. EDT, includes Commander Richard Searfoss, Pilot Scott Altman, Mission Specialists Richard Linnehan, Dafydd (Dave) Williams, M.D., and Kathryn (Kay) Hire, and Payload Specialists Jay Buckey, M.D., and James Pawelczyk, Ph.D KSC-98pc418

Behind Altman are Mission Specialist Dafydd (Dave) Williams, M.D., (waving) with the Canadian Space Agency, and Mission Specialist Kathryn (Kay) Hire. Behind Hire is Mission Specialist Richard Linnehan, D.V.M., and next to Linnehan is Payload Specialist Jay Buckey, M.D. At the rear behind Linnehan is Payload Specialist James Pawelczyk, Ph.D. Their trip to the pad will take about 25 minutes aboard the Astrovan. Once there, they will take their positions in the crew cabin of the Space Shuttle Columbia to await a liftoff during a two-and-a-half hour window that will open at 2:19 p.m. EDT KSC-98pc495
