Day 2: STS-41-G crew begin experiments 1984
The second day of flight STS-41-G, the Challenger crew woke up to Irene Cara’s Flashdance…What a Feeling. Starting with Apollo 15, NASA started playing music to wake up the flight crew. Each song is chosen specifically by the astronauts’ families and typically has a special meaning to their family member or the crew. Or it can be applicable to their daily activities. I haven’t found which astronaut is connected to this song.
The crew lowered the Challenger’s orbit to an altitude of
151 miles, down from 218 miles the day before. Marc Garneau began the Canadian
experiments (CANEX), sponsored by the National Research Council (NRC) of Canada. His experiments included investigations into
medical, atmospheric, climatic, materials, and robotic sciences. One piece of equipment Garneau used was the
Sunphotometer, a handheld instrument which measures solar radiation at several
wavelengths. The Canadian Atmospheric Environment
Service used the readings to measure local atmospheric constituents and to
monitor acidic haze.
Paul Scully-Power (Australian-American astronaut) began
oceanographic observations, and successfully photographed spiral eddies in the
world’s oceans.
David Leestma completed tests on the Orbital Refueling
System remote-controlled hydrazine fuel transfer. The structure was designed to
develop and demonstrate equipment and techniques for refueling satellites in
orbit.
