Launch Highlights

 First launch attempt on Oct. 14 was scrubbed at the T-31 second mark due to a 
failed range safety computer. Second launch attempt on Oct. 15 scrubbed at the 
T-9 minute mark due to a failed S-band transponder on the orbiter. The launch 
was reset for Oct. 18. Countdown proceeded smoothly to liftoff, delayed only by 
several seconds because of an aircraft in launch zone. 

Mission Highlights

Second dedicated Spacelab Life Sciences mission (SLS- 2). Fourteen experiments 
conducted in four areas: regulatory physiology, cardiovascular/cardiopulmonary, 
musculoskeletal and neuroscience. Eight of the experiments focused on crew; six 
on 48 rodents. Crew collected more than 650 different samples from themselves 
and rodents, increasing statistical base for life sciences research. Combined 
data from SLS-1 and SLS-2 will help build comprehensive picture of how humans 
and animals adapt to weightlessness. 

Cardiovascular investigations: Inflight Study of Cardiovascular Deconditioning; 
Cardiovascular Adaptation to Zero Gravity; Pulmonary Function during 
Weightlessness. Regulatory physiology investigations: Fluid Electrolyte 
Regulation during Space flight; Regulation of Blood Volume during Space flight; 
Regulation of Erythropoiesis in Rats during Space flight; Influence of Space 
flight on Erythrokinetics in Man. Musculoskeletal investigations: Protein 
Metabolism during Space flight; Effects of Zero Gravity on the Functional and 
Biochemical Properties of Antigravity Skeletal Muscle; Effects of Microgravity 
on the Electron Microscopy, Histochemistry and Protease Activities of Rat 
Hindlimb Muscles; Pathophysiology of Mineral Loss during Space flight; Bone, 
Calcium and Spaceflight. Neuroscience investigations: Study of the Effects of 
Space Travel on Mammalian Gravity Receptors; Vestibular Experiments in Spacelab. 


For one of the neurovestibular experiments, the Rotating Dome Experiment, crew 
worked with first flight prototype of Astronaut Science Advisor (ASA), a laptop 
computer designed to assist astronauts conducting experiments; also called 
"principal investigator in a box" because it can increase efficiency of 
experiment activities. 

Six rodents were killed and dissected during mission, yielding first tissue 
samples collected in space and not altered by re-exposure to Earth's gravity. 

Other experiments: Orbital Acceleration Research Experiment (OARE); Shuttle 
Amateur Radio Experiment (SAREX). Also performed: Pilot Inflight Landing 
Operations Trainer (PILOT), portable laptop computer simulator to allow pilot 
and commander to maintain proficiency for approach and landing during longer 
missions. 

With completion of her fourth space flight, Lucid accumulated most flight time 
for a female astronaut on the shuttle, 838 hours.
