 The crew is planning to work with a number of experiments that are associated with the United States microgravity payload, which is a platform of experiments in the payload bay overseen by NASA's Marshall Space Flight Center in Huntsville, Alabama. Those experiments are mounted on a support structure in the back end of Columbia's payload bay, which is also filled with that Spartan satellite so the extended duration orbiter pallet of cryogenics. There's a series of experiments. The one on the television now in the downlink from the orbiter is the isothermal dendritic growth experiment, which is an experiment that hopefully may improve manufacturing processes involved in the production of steel, aluminum, and various super alloys that are used in the production of automobiles and airplanes. The investigation is designed to unlock advanced processes that will create some new alloys that may be stronger and may even have better control and more reliable properties than are currently available here on Earth. Go ahead for Solci. I hold myself to begin to record the door opening. We copy, and you can start anytime and we have it on the downlink. Okay, great. This is Mission Control Houston. This television from Columbia's cargo bay showing the shuttle ozone limb experiment as the door opens. The instrument will begin its first observations of the mission. It observes the Earth's horizon from orbit and from ultraviolet light to reflect it off of the Earth's limb or horizon. Gages the amounts of ozone present in Earth's upper atmosphere. Also underway is an experiment on the lower deck of Columbia in a glove box unit that will be the focus of several different experiments during the flight. In that glove box at present is an experiment called the Wedding Characteristics of Emissibles. This video is from that glove box experiment. This experiment again being done in a glove box on the lower deck of Columbia studies metal alloys and mixing of those metal alloys and wedding effects that are caused as those alloys are melted and mixed and that can sometimes cause layering as those alloys are created looking at ways that that wedding could be alleviated. And Kevin, we're up there with you. Commander Kevin Kriegel peddling his way around the world on the bicycle ergometer down in the shuttle's crowded mid-deck area. This is Kriegel's third flight into space after two stints as a pilot aboard the shuttle Discovery on STS-70 in 1995 and again in 1996 on the STS-78 mission which was a two-week microgravity sciences mission aboard Columbia. Columbia, Houston, we know you're busy Kevin but if someone else is available we'd like to maneuver to that biased pitch attitude and we've got the numbers if you need them. Target two which you already have in and then body vector five. The pitch is nine five. Yaw and Omicron are zero. Standing behind Kriegel down in the mid-deck is Ukrainian payload specialist Leonid Kadenyuk. Japanese astronaut Takao Doi poked his head up through the mid-deck area. Actually the bicycle ergometer is set up on the aft flight deck of Columbia. Kadenyuk is standing near the passageway from the flight deck down to the mid-deck where Doi is currently located. At the aft flight deck mission specialists or mission specialist Kulna Chavla will be joined by pilot Steve Lindsay tomorrow for the operation of the shuttle's 50-foot-long robot arm in the deployment of the Spartan satellite which is scheduled at 3.03 p.m. central time tomorrow afternoon. Again Kriegel is peddling the bicycle ergometer on the aft flight deck of Columbia being watched by Leonid Kadenyuk who has been operating the Q experiment today, the collaborative Ukrainian experiment which investigates the progress of plant growth and the absence of gravity. Houston for TGDF deactivation if you could give us a status on that. Copy Steve. Columbia Houston, the orbit four-shift is now trading places with orbit two. It's been a great first day for us. We really enjoyed it. You're after a great start. And Jeff Bandle is here with his team and Ellen Ochoa will be talking to you and look forward to tomorrow working with you on the Spartan deploy. Working with all the animals. See you tomorrow.
